Phylactery 3

I should start by checking the project memory and reviewing the RECORD.md file to get oriented.

This is iteration work, so I should use the iterate skill and take a look at the existing files—beam.js, fx.js, lens.js, and lich.js—to understand the current implementation.

I'm in iterate mode now, focusing on the parts needing his judgment—the rainbow look of the prismatic beam and the recoil feel. The direction is fairly clear: like the lens beam but prismatic and rainbow-colored instead of red, inspired by the skeleton, thinner and originating from the finger, with recoil affecting the hand and arm. I'm going through the relevant files—beam, fx, lens, lich, powers, main, and gem—to understand the existing implementation before making changes.

Iterating on the prismatic beam's rainbow look and recoil feel—checking the lens beam and lich rig now to reuse the accepted lens construction.

Now I'm checking powers.js and main.js to understand how the gesture and pointing logic works, specifically where the fingertip position is captured and how it relates to beam timing—wondering if the pose update runs before or after the beam update, since a one-frame-stale fingertip could cause the beam to not align exactly with the finger.

I realize there's an ordering issue in tick() — powers.tick runs beam.update and fingertip calculation before lich.pose updates, so the beam's origin point is actually one frame stale relative to the arm's motion, which could cause a subtle visible lag since fx.update then draws ribbons from that same stale position.

One fix would be adding a "late" sync step after lich.pose that resets the beam's origin to the current fingertip position, rather than reordering the whole tick sequence. I also want to double check whether the fingertip node actually sits at the true end of the last phalanx bone geometry, since the finger's phalanges might not extend precisely to where I'm calculating the tip -- that mismatch, combined with the stale position and the beam's minimum pixel width at small scale, could all be contributing to the beam not appearing to originate exactly from the lich's finger.

Beyond the positioning issue, I realize the actual color style is wrong too -- the ordered red-to-violet dispersing band doesn't match what's wanted. Instead the beam should keep the lens-style rendering (white-hot core, sheath, glow, noise-eaten edges, flicker, shed sparks, burning spot, pop at start) but recolor the sheath and glow with a drifting pastel rainbow like the skeleton gem's SOFT pattern, where hue shifts with position and time and gets blended with grey for a softer, less saturated look.

Applying the lens beam's visual construction to the prismatic beam while keeping the finger-origin, pierce, and chain mechanics unchanged. For thickness, I'm weighing whether the beam should stay a constant thinner width rather than widening from finger-scale up to 26 cm, since starting at finger-width would make it inconsistent with a uniform ribbon look.

Now I need to check whether the beam is actually anchored to the fingertip precisely or if something (a stale frame, offset tip node, or the flare mote) is making it appear misaligned, so I should render it and inspect closely. There's also the recoil request: the arm should visibly kick back when the beam fires, with the pitch spring getting an impulse, the elbow bending, wrist flicking up, and the shoulder pushed backward for a more realistic reaction.

I'm working out the recoil impulse — a continuous small vibration while channeling, plus a sharper kick at each chain hop, all directed opposite the beam's push direction, factoring in the arm's stiff spring dynamics so it produces a quick kick-and-recover motion. I'll apply impulses to the wrist, elbow, shoulder pitch, and a slight backward lean in the chest/body, then figure out how to implement this in the lich's pose code.

I'm thinking through realistic pistol recoil physics — force at the fingertip pushing back causes the wrist to flip up, the elbow to flex more, and the shoulder to rise, producing muzzle climb, so I need to translate that into signed adjustments on the wrist, elbow, and shoulder spring targets.

Since the arm points down-forward toward the snakes, a straight-arm force along the axis wouldn't torque the shoulder, so the recoil really needs to come from the elbow bending and the wrist flicking, with the shoulder pitch kicking the hand up toward horizontal and back to sell the muzzle-climb feel.

The recoil also nudges the chest and head back slightly, and I'm working out how the torso should twist: pushing the casting-side shoulder backward corresponds to a positive yaw rotation about the y-axis, since that rotation carries a point on the +x side toward -z.

I should also make the recoil continuous during the channel — a steady deflection plus a subtle tremor, with the arm springing forward a bit when the beam cuts off, mimicking natural spring dynamics. For the beam visuals, I want to mirror the lens beam style but swap the red core for something prismatic, keeping the same warm white core color.

The sheath should take on a shifting rainbow hue rather than the orange-to-red gradient, similar to how the skeleton's pattern drifts hue zones over time. I need to keep saturation punchy enough that it reads as rainbow rather than washing out to white once bloom and additive blending are applied at this resolution.

Since he only said "more like a rainbow sort of thing, inspired by the skeleton himself" without fully specifying the exact pattern, this feels like a case where I should present a couple of variants rather than lock into one interpretation.

There are two plausible readings: soft hue zones flowing along the beam's length, or having the beam literally inherit the same colour field as the skeleton's bones — so the hue at any point on the beam matches what that same world position would look like on his body, making the beam feel like an extension of him. That second option is appealing thematically, but I'm noting the underlying hue field varies slowly across space, so over a long beam it might not read as much variation.

I could also combine ideas — keep the hue tied to his bone colour field, but layer in scrolling brightness bands for a sense of energy flowing from his finger to the target. I'm also thinking about whether to offer multiple beam-style variants toggled by a key, similar to how past effects had toggle options.

I should also weigh saturation — his bones sit at a subtle pastel level, so a beam matching that would look almost white. What matters more is how thin the beam reads on screen: at room-camera distance the beam is only 1-2 pixels wide, while the lens beam near the finger is thicker, around 7-8 pixels, tapering down toward the tip.

A beam that narrow can't show rainbow structure across its width, so color needs to run along its length instead, with bloom carrying the visual spread. I'm settling on roughly 7-8 cm core width — about a third of the 22 cm lens — tapering from the fingertip's ~1.5 cm up to full width over the first 25 cm so it visibly emerges rather than appearing as a blob. I'm also questioning whether a bright flare mote at the fingertip is a good idea, since a 10 cm glowing dot there would obscure the finger and make the beam look like it's coming from a ball floating near the hand instead.

Adding this light at startup keeps material recompilation costs manageable since the count stays constant, and one more point light among the existing fire, lens, and beam lights won't strain the pipeline much. I'm keeping the existing prismatic shatter effect at the beam's endpoint, just reconsidering whether it needs smoke since it's light-based rather than fire-based.

For the chain effect I'm keeping both sweep and bounce modes, and mirroring the lens beam's visual details—the initial pop-wider effect, flicker frequencies, and spark shedding—into this new beam style. Now I'm adding a fourth fx.js style for the prismatic laser, working out how to get world-space position into the fragment shader by interpolating the beam's start and end points through the along-beam parameter.

I'm confirming this interpolation stays perspective-correct since it flows through a standard varying, then adapting the skeleton's hue formula—based on a dot product with a directional vector, faceting, and time offset—to drive the beam's rainbow coloring.

Now I'm weighing three approaches for the beam's color motion: a flowing rainbow whose phase matches the finger's bone-hue for continuity, streaming outward at a readable ~3 m/s with roughly a 1.5 m hue cycle; a static version where color stays fixed in space and only brightness animates; or a faster full-spectrum sweep.

I'll settle on three keyed looks—his colors streaming (default), his colors held still, and a white core with rainbow-only edges like a prismatic sheath, with white-hot cores shared between the first two variants.

Actually, I think I should just build it and see the render first before locking in the variants, then check the skeleton's fingertip geometry against where the bone mesh actually ends.

Let me check how round 13 captured its beam stills, looking at those scratch JSON files.

The current close camera is too far from the hand, so I need to compute the fingertip's approximate position and place an inspection view_at right there, evaluating it from the lich's known placement coordinates.

I'm also noticing a white flare dot at the hand in frame c_00 — that's likely both flares overlapping at the tip during the shoot phase, which explains why it doesn't look like it's coming exactly from the finger. I'll set up a closer view_at shot from the side, near dist 1.2, to check this.

I'm noticing the flare ball at the fingertip is scaled too large relative to its intended size, so it visually blooms into a bright white sphere that obscures the finger, making the beam look like it originates from a floating ball rather than the hand itself.

The ball also appears offset a few centimeters from the actual fingertip position, which could point to a stale-frame timing issue or the tip node being placed ahead of the real bone end, and the ribbon effect starts from that ball's center rather than the fingertip. I'm also questioning whether the rainbow dispersion pattern reads as "wrong," and want to check the lich's bone coloring in close-up lighting to inform a more accurate prismatic palette — I should pull up the earlier pattern reference sheet from round 8 for comparison.

I'm thinking of a soft pastel palette drifting across the figure — lime, pink, lilac, peach, pale cyan blending together like opal — applied to the same beam structure with its hot core, sheath, glow, and noise edges.

I realize the beam looking like it starts from a floating ball rather than the fingertip is because the flare is too large and the tip sample lags a tick behind the hand's actual position. I'm planning a new "prism laser" ribbon style using an opal-like hue field tied to world position, with a white-hot core and a width taper concentrated in the first 20cm rather than spread linearly — possibly by splitting the ribbon into a short taper segment plus the main length.

Working through the taper math now, I decide to keep the ribbon vertex width constant at its max and instead handle the nonlinear taper in the fragment shader by scaling the cross-section coordinate against a smoothstep-based taper function, so anything outside the tapered width gets masked to black and disappears under additive blending.

Now I'm redesigning beam.js around the lens-beam look: a wider pop at the start, flickering, prismatic sparks shedding along the length, and a hot white core at the impact point without a big smoke cloud since it's pure light. I'm scaling down the finger glow to a small 2-3 cm tip plus a point light that makes his hand's bones flash prismatic, and rethinking widths so the beam tapers thinner from body to finger than the lens version.

At the room camera distance, that 7 cm body width comes out to only a couple pixels, so I'll rely on glow to sell it. Behavior-wise I'm keeping the existing targeting logic — shoot to the first snake, dwell, then sweep/bounce — and confirming the beam should stay instant like the lens rather than visibly traveling, since it pierces rather than sweeps across the target. I also need to fix the stale fingertip issue by adding a late-update step that re-reads the fingertip position after the lich's pose update and refreshes the beam segment and flare positions accordingly.

I should compute finger direction as tip minus the last segment's base, offset by the bone radius so the beam originates at the surface. But I'm also questioning whether the finger actually aims at the target — the wrist/finger rotation chain might not align with the beam's trajectory, making it look disconnected. I want to measure the angle between finger direction and beam direction, and if it's too large, rotate the wrist post-pose to aim the finger at the target.

Then there's recoil: kicking impulses into the arm springs (shoulder, elbow, wrist) plus chest/head, strongest at beam start and smaller at each chain hit, with continuous tremor while channelling and a forward release spring once the beam ends.

I'm calculating the needed initial velocities for each joint's spring given their frequencies and damping — roughly 6 rad/s for the shoulder kick, 9.5 for the elbow, and 15 for the wrist flick — while keeping the elbow rotation clamped within its natural range.

I'll need to double-check the sign conventions for both the elbow and wrist targets, since bending direction and flick direction depend on arm orientation. I'm planning to verify numerically by applying a test impulse, stepping the simulation forward, and measuring whether the fingertip actually moves backward and upward relative to the beam direction, adjusting signs until that's confirmed.

The recoil force should mostly hit the hand and arm, maybe a touch of shoulder/chest follow-through for realism, and possibly a small backward velocity nudge on the whole body -- but I'll keep that subtle. I'm also thinking about making the head's point light cycle through the beam's hue so it casts shifting pastel tones on the snake and floor, and adding a light near the fingers so the gem material makes his arm look prismatic when the beam fires -- a nice visual tie-in, though I need to watch the total light count since each added PointLight affects all materials.

The impact flare needs rethinking too -- the current white disc plus ring of motes echoes the flash effect he already disliked on the lens beam. I'll strip out the disc and ring and replace them with the lens's approach instead: a small hot white point paired with a spray of prismatic sparks at the hit location, matching the treatment he preferred. For player-facing customization, I'm planning to assign a free key to let them control the beam colour.

A toggle between both saturation levels seems like the right call, defaulting to the subtle pastel since that matches "inspired by the skeleton" — though on an additive HDR beam with bloom, pastel might wash out to near-white, so I'll need to tune it once I build and see. I'm also mapping out free keys for the HUD — using K for beam colour alongside the existing C for beam chain and L for lens beam — and thinking about how chain mode C should toggle between sweep and bounce behavior.

I'm checking ribbon minimum width against the room camera's scale, and working through the flow speed math for the lens noise pattern and hue streaming — trying to pick a cycle rate that won't strobe at 60fps while still reading as motion rather than a slow drift.

I want continuity between the finger bone's hue phase and the beam's phase at the fingertip, so I'm tying the beam's phase formula back to the same dot-product and time-decay terms used for the held gem, just adding the spatial streaming term.

Now I'm writing the opal hue function for gem.js, converting a phase value into RGB with smooth clamped color bands, then deciding on how much grey to mix in for a full-rainbow look versus a subtler version.

I'm setting up per-ribbon shader parameters, encoding the look index and taper width into vertex attributes, and working out how style 4's fragment shader computes position along the ribbon, tapering width, and constant world-space thickness at each end.

Now I'm writing the fragment logic for edge falloff and noise-based lensing on the ribbon edges, plus figuring out the phase offset for the hue streaming effect based on each ribbon's starting position.

Writing shader color blend...

With HDR tone mapping the pastel would wash toward near-white, so I'm weighing options: his own colour palette versus full rainbow saturation, and whether the light streams continuously or holds steady — maybe three variants worth offering. Actually, I should calibrate saturation to match how his bones already read on screen in diffuse lighting (colourful but not HDR-blown), so the beam feels consistent with that established look.

Now I'm moving to writing the beam code itself — segment states for shoot/dwell/move, ribbon width tapering from fingertip to body, a pop-and-flick animation using layered sine waves, and prismatic spark particles shed along the beam's length similar to the lens effect but with a multi-hue tint instead of orange.

I'm adding a small bright mote at the fingertip with a point light matching the beam's hue, plus a brief flare and spit of prismatic sparks when firing starts. For recoil I'm layering a strong kick at initial fire, smaller kicks on each new hit, steady pressure with tremor while active, and a release at the end, and I still need to check the angle between the finger direction and the beam during implementation.

Now I'm working out how recoil integrates into the pose system: storing pending kick impulses per arm alongside a continuous press weight, then applying them across the arm's spring targets (position, elbow, wrist, rotation, plus shoulder curl and yaw and hand pitch) before clearing the pending kick, while continuous press adds an ongoing deflection force scaled by each spring's frequency squared.

I'm deciding to apply these kicks as direct velocity impulses to the spring state before the spring integration step runs, at the very start of pose(), so chest and head springs get the kick before their own spring calls. I'm also working through the sign convention for the shoulder pitch — since pointing forward corresponds to a negative angle, raising the arm means pushing that velocity more negative, though I need to double check this against how the clamp range is set up.

Now I'm reasoning through what direction recoil should push the arm — since the beam aims down at the floor-level snakes from the raised shoulder position, the recoil along the beam axis translates into a combination of upward shoulder rotation and elbow flexion, so I'm planning to verify the resulting fingertip displacement matches this intent numerically and visually.

I'm working out the wrist's rotation order in three.js's Euler XYZ convention, since the y-axis twist (rotating the hand about its long axis) needs to be applied before the x-axis flex relative to the forearm frame for the hand pose to read correctly.

I'm also tracing how the pointing gesture composes through the chain: the index finger curling about z, the hand's twist, the wrist's x rotation, and the elbow bend all need to align so the finger roughly follows the forearm and upper arm direction, letting me estimate the beam from fingertip to target.

Since pick_arm already selects the correct side, most cases stay aligned, but when the target crosses the body the roll clamp prevents the arm from tracking it exactly, so a wrist correction that nudges the bend based on the angle between finger direction and target direction would help close the gap.

I should measure this before committing. I also notice the beam's tip position is set before the pose update, making it a tick stale, so I'll fix that by hooking into after_pose. Time to start writing the code, beginning with fx.js style 4.

I identified two issues causing the beam not to exit the finger: a 10 cm flare ball at the fingertip is obscuring it, and the beam samples fingertip position a tick before the arm's pose updates, causing it to lag behind hand movement. I'm now rebuilding the beam based on the lens beam's construction.

I notice lich.js creates a point light but never actually adds it to the scene, which seems like an oversight. Now I'm moving to fx.js to implement style 4, editing the vertex shader to add new varyings for pixel position, width, and phase offset, with the width fixed to a constant for this style.

I'm reworking the phase formula so the color at the finger's position stays anchored to field0 while the pattern flows outward as x increases over time, meaning I need a phase function of the form g(x minus velocity times time).

I realize I should drop the "matching the finger's colour" claim and instead just let the hue stream outward: phase equals a base hue minus 0.42 times x plus 1.008 times time, which gives a steady 2.4 m/s streaming effect with about 1 Hz hue cycling at the fingertip. I'm now wondering if that fingertip cycling rate feels too fast or flashy given the wavelength is 2.4 meters per cycle.

For the "HELD" state I want the phase to actually reflect the underlying field structure — a dot product with a weight vector scaled down, plus a slow time drift and a touch of noise.

I need to set the hue value for style 4 by passing the look index through the shader's vHue variable. Now I'm working on lich.js to add fingertip direction, kick, press, and wrist alignment logic, defining kick and press pose data structures...

Writing kick and press logic...

I'm adding a chest spring impulse that applies kick velocity to position, energy, width, rotation, and shoulder springs, noting that applying it after the chest spring steps this tick is fine since it'll take effect next tick. I'm also working out a continuous pressure force formula using angular frequency squared times amplitude, plus a tremor term, and setting up a helper function to compute this — I'll need to test the signs numerically to get the direction right.

To figure out the sign conventions, I'm considering setting up a test harness where I pose the lich pointing at a target, apply each kick component separately, and measure fingertip displacement relative to the baseline — though the baseline itself moves since the arm follows the head, complicating direct comparison. A cleaner approach would be to temporarily expose the lich's nodes and analytically rotate the elbow by a small delta, update the world matrix, and compare fingertip position before and after to directly read off the sign of each joint's effect.

I'm testing how each joint parameter on the right arm affects tip position, checking shoulder x and elbow x adjustments to see which direction raises or lowers the arm.

Now I'm noticing the finger and beam are off by 16°, so I need to correct the wrist rotation to align them. I'm planning to compute the desired direction from tip to target, find the rotation needed to align the finger, and apply a fraction of that correction to the wrist's quaternion — working out how the world-space correction quaternion should combine with the wrist's parent-relative rotation.

Since the tip position shifts once the wrist rotates, I note that one or two correction passes per frame should be enough to keep things stable, and I'm moving on to sketch out the recoil animation for the kickback and elbow motion.

For the "thrown back" effect, I realize a straight arm can't retreat along the beam through elbow flexion alone — that mostly sweeps the tip sideways. Real backward motion has to come from the shoulder itself shifting, so I'm factoring in chest yaw on the casting side to pull the shoulder back.

Also considering a small whole-body impulse — the lich drifting back a bit on each shot as recoil. I should check how mover.js handles velocity and collision to see if I can add that kind of impulse safely without breaking nav bounds.

A shove should feel physical: applying an impulse to velocity rather than position lets the body's acceleration spike naturally swing the limbs, like a reactive ragdoll response. Calculating it out, a 0.3 m/s velocity change over one frame gives roughly 18 m/s² of acceleration—enough to visibly kick the legs and arms as the body drifts back a few centimeters, decaying smoothly afterward via the tau parameter.

That felt like too much whole-body motion for what was asked, so I'm scaling back to just the recoil propagating from hand through arm to shoulder and slightly into the chest, keeping it minimal and realistic rather than a full-body shove. Now I'm sketching the implementation plan: adding a kick/press API, aligning the wrist to the target direction while pointing, and a helper for computing the fingertip direction, along with tuning recoil spring constants for the shoulder, elbow, and wrist so the kickback looks like a believable pistol-style muzzle climb rather than an exaggerated flail.

I'm continuing to fine-tune the recoil amplitudes and damping across the finger, chest, and head, plus adding a subtle high-frequency tremor during the sustained beam to sell the sense of continuous force feedback.

Since spring-based tremor at 23 Hz gets damped to nothing, I'll apply that shake directly to rotation values instead, layering a sine offset onto the wrist rotation. I'm also double-checking the chest yaw math -- working through the rotation matrix to confirm that a positive yaw on his left arm side correctly twists the torso backward.

So kicking that arm's chest yaw velocity should rotate the shoulder back correctly given the body frame convention, and since it's mixed with the gaze spring at low frequency, a 1.5*s kick stays small at peak. I still need to decide where beam.js calls the press function each tick -- during cast, burn-in, and channel -- making sure it resets to zero when the beam ends rather than leaving stale press values.

Wrist alignment needs to happen at the very end of the pose function, after all body and chest rotations are set, since the alignment depends on the final world matrices. I'll update the world matrix once per tick for arms with active pointing, then compute the fingertip and base positions in world space to derive the finger direction vector.

The desired direction points from the wrist toward the target point, and I clamp the rotation to a max angle before slerping by the pointing weight. I need to transform this rotation into the wrist's local space using the elbow's world quaternion, then apply it to the wrist joint and refresh the world matrix down that subtree so fingertip queries stay accurate. I'm also considering how a recoil-style wrist flick might interact with this alignment system.

I could low-pass the correction with a time constant around 0.25s so it tracks the slow aim but not the fast kick, though that still partially fights the kick. Better: freeze or slow the correction update whenever a recoil envelope is elevated, or cleaner yet, treat recoil as a fully separate additive layer applied after alignment rather than feeding into the same pose the correction reads from.

A cleaner approach is to express the wrist recoil in world space instead — rotating the hand about the axis perpendicular to the beam and world up, so the fingertip visibly kicks upward regardless of the local frame. The shoulder and elbow springs stay untouched, so their visible motion (arm raising and flexing) still comes through even though the wrist alignment partially re-aims toward the target afterward.

Confirming the rotation lifts toward up as intended, and applying that at the wrist pivot by premultiplying the local rotation with the recoil quaternion in parent space, combining with the alignment rotation. I'm also adding small direct impulses to the chest springs, and setting up continuous press behavior where the recoil springs get sustained target deflections proportional to press strength, plus an additive tremor component.

When the beam ends, press drops to zero and the springs release naturally back forward, and the hand-follows-head behavior during channeling stays as already implemented. Now I'll write the actual changes to lich.js.

I'm adding a recoil layer to the casting arm—shoulder rise, elbow give, finger flick, and a slight jolt back—plus correcting the wrist so the index finger aligns exactly with the beam, which was off by 16°.

I'm working out the correction for the wrist's local quaternion: since the world rotation should be Cw times the original world rotation, I need to premultiply the local quaternion by the elbow's inverse world rotation times the correction times the elbow's world rotation, giving the transform to apply before the existing local rotation.

This rotates the wrist about its own joint origin, so the finger transforms correctly under Cw with only a small residual error in the tip-to-target direction, which is acceptable. I'm also confirming the world matrix update ordering is correct for reading finger positions, and double-checking the sign conventions for the flick kick, press target, shoulder pitch, and elbow bend so they all produce upward motion consistently across both arms.

Now I'm working through the remaining sign conventions: chest pitch kicks the torso backward, head pitch jolts it back, and chest yaw rotates the correct shoulder backward depending on arm side. I'm also planning to clamp the wrist correction to about 40 degrees plus flick, and rewrite beam.js so the aim point correctly switches between the target snake point during aim and the beam head during channel — this requires adding an after_pose hook that runs after lich.pose to keep the stale tip position updated.

Writing beam.js constants...

I'm adding a secondary light at the fingertip mixed with white for prismatic bone effects, then replacing the impact burn-in with a small hot point and a burst of prismatic sparks instead of the disc/ring, plus a continuous white-hot flickering ball at the head with core sparks.

At the fingertip I'm giving a tiny hugging core glow, then adding a brief kick flare with a handful of sparks sprayed sideways/perpendicular rather than straight backward, so it reads as recoil without looking like a muzzle flash.

For the beam segments, I'm defining pop intensity curves — a decaying flare for bounce segments as they trigger, and a smaller flare at each new hit for the sweep — plus width tapering logic so bounce segments start full-width instead of tapering from a fingertip.

I'm working out timing for the width grow-in using a smoothstep over the head's travel time, then setting up recoil calls — kicking the arm on cast and on each burn-in tick, and pressing proportional to the on/end curves, releasing when the beam ends. I'm also fixing a stale p0 issue by anchoring the beam's origin just ahead of the fingertip bone cap in after_pose.

For BOUNCE mode, I'll set later segments' p0 to the previous target ring, keeping the extend, busy, and aim_point API unchanged along with the existing pierce and shatter effects. I still need to decide on the head light's color before writing the file.

I'm double-checking the unused clamp import and verifying that the spark and mote initialization logic correctly handles position and hue overrides without conflicts.

I'm tracing through the bite logic, ribbon hue propagation, and segment width calculations to make sure they're recalculated properly on each pose update, plus confirming the light color normalization and the new light count from the lich's hand. Then I'm wiring up powers.js's after_pose hook into main.js's tick loop alongside the look key and HUD updates, making sure the fingertip position used for aiming stays fresh when cast re-reads it.

I'm checking the beam's visual details — it tapers properly from the fingertip with a purple-red glowing mote, and the sheath shows a pink/magenta edge around a mostly white core, though the color transition is only partially visible in the short viewing distance.

The white core seems too dominant compared to the prismatic sheath, so I should shrink its fraction to let more color show through, and the spark particles look too white too — I'll boost their color saturation. There's also a lingering 9.8° angle discrepancy between the finger and beam that shouldn't exist if the correction were working properly at full pull, so I'm tracing through how the beam head position feeds into the finger direction correction to find where that residual comes from.

The purple fingertip glow mote reads too much like a ball — I'll shrink and dim it. Then I want to check the room and close cameras for the actual game view, capture burst frames for the recoil sequence, and verify hue variety along the beam length. I'll fix these issues before capturing final reference sets: room camera crops, arm recoil frames, and close-up looks.

Since the room camera is far away, I should crop around the lich to get a better view, scaling the region up 3x with nearest-neighbor for clarity. First I need to check the room sheet to locate exactly where the lich sits on screen.

I don't actually see the lich in these frames, just the beam near the pool—maybe he's hidden in a darker region. I'm going to crop and zoom into the room frames around the beam area to look closer.

I remember that heredocs in the Bash tool halve backslashes, so I should avoid relying on literal backslash escapes here and instead use chr(92) or os.path.basename to handle the path correctly.

I'm trying to place the lich in the crop near the bottom-left, and reconsidering the wiggly white shape as the pierced snake glowing with light. From the room camera's view, the beam appears mostly as a thin white line with only faint hints of green or pink color at a couple pixels.

I'm working through why the beam reads as white rather than colored — it comes down to HDR tone mapping: once channels exceed 1 after exposure multiplication, they clip to white, which washes out subtler hues like pastels while an orange beam survives because its low channels stay under the clip threshold. So to preserve visible color at a distance, I need to lower the sheath's HDR multiplier so the dominant channel stays closer to 1, keep the white core thin, and let the bloom carry the color into the surrounding pixels rather than clipping it away.

I should suppress the white core entirely at small pixel widths, only letting it appear once the beam is wide enough on screen (using something like a smoothstep threshold on the beam's pixel width) — that way a narrow beam reads purely as its sheath color with a brighter center, giving that "rainbow beam" look from the room camera. Now I want to check how this plays out on the close camera reference sheet too.

I notice the snake spawned far from the egg on this one, unlike the "force near" targeting rule I saw before—odd, but not worth worrying about. Looking at the close-up camera shot, the beam's color barely reads against the white core, especially at the tint near the fingers, so I want to scale down or remove the white core entirely when the beam is thin on screen, say at 3px or less, to let the color show through better.

Lowering the HDR clipping factor and adjusting the sheath multiplier so bloom carries more of the brightness instead of the core, while also tuning saturation since the bones read too pastel in-scene compared to their base color. I'm rewriting the style-4 color logic so the white core fades out smoothly based on pixel width, blending toward a brighter center only when the beam is thick enough, then checking hue variation along the beam length to confirm it cycles through 2-3 colors as expected at the close camera distance.

I'm realizing the beam looks whitish because the pixel width is so thin that the core color clips out, and the sheath's brightness multiplier pushes the channels past the normalized range, combined with the bloom threshold adding an extra white glow on top.

Also considering the tone mapping's soft-shoulder knee — if it compresses per-channel rather than luminance, bright coloured pixels desaturate toward white. I should actually check by sampling pixel colors along the beam in room_04 to see the real hue/saturation values.

I'm checking how the per-channel shoulder handles saturation for a pastel with 30% grey mixed in—working out that a pure red hue normalizes to values where the red channel overshoots past 1, pushing it toward that near-white clipping behavior.

So for the beam to actually read as colorful rather than pastel-washed, I'd want less grey mixed in and a lower overall scale so the shoulder doesn't crush the hue. Now I'm trying to pin down the actual pixel coordinates of the beam in the cropped image, working through the scale and offset math to locate where it sits relative to the lich's hand and the snake, though the coordinates I'm getting seem to fall outside the tile bounds.

Rather than keep fumbling with screen-space geometry by hand, I'm considering just writing a readback helper that projects the fingertip and head positions to screen space and samples pixels directly along that line from the render target, which would give me ground truth instead of guessing. Meanwhile I'm also reasoning through what grey mix and multiplier would produce a saturated center pixel around 1.0-1.2 max channel with other channels under 0.3.

Checking the K multiplier math against pastel tones I saw on screen — those bones read as moderately saturated lime, pink, and lilac, so a grey mix around 0.14-0.2 with reduced brightness seems like a reasonable approximation. I'm also considering how the bloom threshold picks up the bright colored parts and how haze in the beam shaft affects the room's view.

Checking the color cycling rate along the beam — at 0.42 cycles per meter over a roughly 5-meter beam, that's about two full cycles, which would explain the candy-stripe pattern of pink, yellow, cyan repeating as seen from the room camera.

The beam now reads as a rainbow gradient of yellow-green, cyan, and pink along its length, which looks nice. The pierced snake currently glows a stark solid white, but I'm wondering if it should instead pick up the same prismatic colors as the beam, since a plain white snake next to a rainbow beam feels a bit disconnected even though that effect wasn't specified in the brief.

I want to check whether the snake's glow color is settable so I can tint it with those opal tones as light bleeds from the wound, keeping the change modest. I should also verify the lich's hand light intensity on his arm in the close view, and set up a side-view test to track the fingertip's displacement relative to the shoulder and chest over the ticks following a cast, to check recoil behavior.

I'm looking at how the snake's glow blends white with the rainbow hue at 60% strength, which clips to white at higher HDR intensity — and since this formula is shared with the leakage effect, I need a way to adjust the beam fill without breaking leakage's later appearance.

I'll dial back the brightness slightly and lean more into the hue mix to keep it below clipping while still reading as prismatic. Since it's part of the same beam attack the user flagged as needing rainbow tones instead of white, tinting the snake to match feels within scope, though I should note that this will subtly shift leakage's glow toward more color and less white since they share the same attribute channel — separating them would need a new attribute component, which feels like overkill right now, so I'll accept the shared change and flag it in the handover.

The finger alignment at aim is quite tight, within about 0.1-1°. Looking at the fire tick, I notice the tip position relative to the shoulder shifts by roughly 28 cm, but that's likely because during the hold phase the tracked point follows the beam head, which starts at the tip and then shoots outward — so I need to account for that offset before treating it as actual hand movement.

After the kick settles, the hand ends up about 8 cm higher than its pre-fire position, with a peak rise of 28 cm — for a 0.7 m arm that's roughly 23° of shoulder rotation, which feels a bit much compared to a real handgun's 10-20° recoil rise. Since this is a stylized beam weapon I could justify it as "magic force," but I'm leaning toward scaling the kick down to around 0.7x to get a peak closer to 18 cm.

Looking at a second cast, I notice something odd at tick 65: the finger-to-beam angle suddenly jumps to 60° and the hand position shifts about 15 cm in a single tick — a discontinuity. This likely happens because during the shoot phase the beam's head starts right at the tip position, which is nearly collinear with the arm, so the direction used for the wrist correction becomes ill-defined and swings wildly, probably hitting the 0.7 rad correction cap and causing the snap.

The fix should be to have the arm aim toward the beam's target direction rather than the current head position whenever the head is very close to the tip — since the head travels in a straight line from tip to target, using the target direction should smooth out the aim and avoid the noisy jump.

For BOUNCE mode there's a separate issue: the arm currently follows the moving head across successive snakes, but the finger's beam segment is fixed to the first snake, so pointing at later snakes would misalign the beam entirely. I need aim_point to use the first target's position for BOUNCE, while SWEEP can keep following the head (or fall back to the goal when the head is near the tip). I'll also add a guard so that when the point-to-tip distance is under 0.3m, the alignment weight is zeroed out to avoid the jitter.

There's still a jump at tick 65, where the position shifts oddly along the axis in one tick before settling back. This might be caused by a recoil kick from a bite motion firing as the head reaches the snake, which would explain the sudden hand displacement.

The wrist correction itself isn't spring-smoothed, so if the needed correction angle jumps sharply or the direction flips near the tip, that could explain the sudden snap. I should add more logging around ticks 61-69, tracking point position, head, tip, and which arm gets picked to pin down exactly where the jump occurs.

I'm tracing the aim point switching between the head and snake ring across ticks, checking that it's consistent once the head reaches its target—but I notice the tip position jumps unexpectedly at tick 65, which needs investigating.

The jump happens in a single tick and holds for a few frames before reverting, suggesting some clamp or discrete trigger is engaging rather than a smooth continuous change. I'm ruling out the kick-on-bite mechanic since that affects velocity, not position directly, and checking the shoulder rotation clamp and finger alignment logic, but neither explains a discrete positional jump. I'm now looking at the wrist quaternion premultiply to see if that's the source.

Since slerp always takes the shortest path, w stays non-negative, so that's not the culprit. I'm now suspecting the tip's 13cm jump comes from somewhere else — maybe the roll clamp, where the position value gets capped against a mix of limits rather than the target, could let it drift and snap.

But that would produce a kink, not a jump, so I'm ruling it out. I check the elbow clamp against recoil offsets and the chest yaw — both look fine, no discontinuities there. I'm tracing through where `pose` is computed, looking at how the fingertip position gets read after the game tick runs, following the sequence through pose calculation and the post-pose power effects to see where the jump could originate.

Since tracing the code path isn't pinpointing it, I decide to just expose the recoil values directly for debugging by attaching them to the lich object, so I can print per-tick rotation and quaternion values and see exactly where things go wrong.

I'm noticing the wrist correction value jumps oddly at tick 65 before returning to its prior range at tick 69. This looks tied to the skip condition based on point distance to the tip — maybe the distant snake target is triggering a much smaller correction than expected.

Wait, actually the discontinuity could come from an angle cap: if the finger's needed correction exceeds the ~0.7 rad limit, it gets scaled down, and a large mismatch in finger direction (~60°) could cause the jump. I'm also considering whether the Euler decomposition itself is flipping between equivalent representations near a gimbal-like case, though the 13cm fingertip shift suggests this is a genuine pose change — possibly triggered by the bite/kick event around tick 64.

Now I'm scrutinizing the cap-clamping code that limits rotation angle to 0.7 radians, and I think there's a bug in how it rescales the quaternion using slerpQuaternions — the arguments look swapped, meaning it's copying the identity into the target rather than interpolating properly between the identity and the corrected quaternion.

If that's the bug, whenever the correction exceeds 0.7 radians, the entire correction gets zeroed out, causing a visible jump. The fix requires copying the correction to a temp quaternion first, then slerping from identity toward it. I'm also wondering if the 60-degree mismatches are being caused by the recoil animation raising and bending the arm enough that the finger swings far off its intended pose.

Actually, I realize the alignment logic is fighting the recoil — the wrist correction re-aims the finger toward target, effectively canceling out the arm's recoil movement, which looks wrong since a real hand should rotate with the recoiling arm rather than compensate against it. The better fix is to compute the alignment correction using the pose before recoil is applied, not after.

Still working out arm rotation math...

The recoil now looks smoother: the tip rises from -24.8 to +11, about 36 cm, with the finger tipping up 42° off the beam and pulling back 9 cm — a large motion. Then during the press, the finger holds around 8-9° off the beam axis (combining the pitch, elbow, and wrist rotations), while the beam still projects from the fingertip toward the target at that offset angle.

Since the beam is a straight line from tip to target, a 42° swing of the finger at the kick's peak creates a visible mismatch — the beam can't bend to follow the finger's rotation unless I curve its starting direction. This mirrors how a kicked laser pointer would sweep its spot upward in reality, so for visual punch I'm considering drawing the beam as a slight Bézier curve leaving along the finger's direction and bending toward the target, which would preserve the "emerges exactly from the fingertip" feel while still selling the kick as a whip — though the ribbon geometry is currently a straight quad, so this would need rework.

I'm now settling on toning down the recoil instead: dropping peak finger deviation to around 18-19° with a smaller ~4° press deviation, scaling back the shoulder/elbow/wrist velocity kicks proportionally (~0.45x) so the tip rises about 16cm rather than the earlier more exaggerated motion.

The visible "backward" motion should mostly come from elbow flex rather than shoulder raise, since the shoulder rotation reads as upward while the elbow bend reads as pulling back — so I want to weight the animation toward elbow flexion to sell the recoil look while keeping the wrist flick smaller.

Let me plug in actual numbers: upper arm around 0.30 and forearm-to-fingertip around 0.40. Working through the geometry so the fingertip stays on the beam line, I find the elbow flex needs to be roughly 1.75 times the shoulder rotation, and the arm shortens along the line proportionally to the square of the rotation angle.

For a 5cm pullback, that gives a shoulder angle around 25° and elbow angle near 44°, with the forearm tilting about 19° relative to the line — which suggests a natural wrist-flick recoil motion rather than trying to force perfect alignment. I think the cleanest approach is to simplify: just kick the hand and arm up and back together, keeping the elbow doing more of the work, rather than fighting with exact angle matching.

Even distributing the rotation across shoulder, elbow, and wrist, the finger still ends up deviating around 22° from the target line since all three joints rotate the same direction. Rather than fight this mismatch further, I'm considering letting the beam itself start along the finger's actual direction and curve toward the target — a whip effect that would turn the misalignment into visual juice instead of a bug.

Working out the Bézier curve segmentation for this — splitting the beam into ribbons along a quadratic curve from fingertip through a control point to the target, so it looks straight in the normal case but bends during recoil.

I should add more segments (8 instead of 6) so each joint's bend angle stays under a few degrees, which will hide the small additive-overlap notches at ribbon joints even on wide beams at close range.

I need to pass per-ribbon x0 and origin info through vertex attributes so the taper and streaming field calculations stay continuous across pieces rather than resetting per-piece — the width taper should use global position while the streaming effect needs the beam's true origin, not each piece's local p0.

I'll restructure to use a vec2 attribute (x0, phase0), computing the phase on the CPU from the tip position and clock time so style 4's streaming field reads correctly across the whole ribbon.

The recoil kick pushes the finger 40° off the beam's line at its peak. I'll reduce the kick strength and render the beam as a smooth curve that always exits along the finger and bends toward the target, turning the kick into a visible whip effect instead of a mismatch.

I should update the fx.js header comment to note that style 4 is drawn in pieces along a curve. Then for beam.js, I'm restructuring segments to be chains of pieces—each segment holds an array of ribbon pieces that get positioned along a curve during after_pose.

For curved segments, I'm computing a control point offset from the start position along the facing direction, then using a quadratic Bézier between the segment endpoints to place each piece; when the facing direction aligns with the straight path, the curve naturally flattens out. I'm dividing the curve into pieces by parameter fraction, tracking cumulative length for texture offset, and sourcing the phase from the field at the tip. Sparks and hit-detection can sample from piece endpoints or just use the head as before. I want to restructure the segment logic across update, after_pose, release, and cast into shared helpers for releasing and iterating pieces, and I'm reconsidering the recoil kick/press values now that the curve makes the beam whip visibly from the fingertip.

Checking the ribbon pool capacity of 160 against worst-case spawn demand: with bounce chains reaching up to 8 targets and 10 pieces per segment, that's potentially 80 pieces plus lens and wind ribbons, so it should fit but it's tight, especially if the pool gets clogged with held ribbons and spawning has to loop through to find free slots.

Actually, to avoid any risk of stealing a held ribbon, I'll bump the pool size up to 240 for safety. Now I'm also working out the angle between the finger's direction and the direction of the first piece.

I'm noticing the tip rises 8 cm in a single tick during the hold phase, likely because the arm's target switches from the snake to the aim point right as it's already lifting toward that position during the aim transition.

So the fire moment isn't a settled pose — the gesture's natural upward motion is still happening, meaning the measured rise mixes recoil with ongoing arm movement, and the 22° finger deviation peak likewise blends recoil flick with that motion. The second kick around tick 11 lines up with the bite timing, which checks out.

Now I want to see this visually — I'll set up a side-view camera near the shoulder, about 2.2 m out, and grab frames every 2 ticks spanning from just before firing to 30 ticks after, so I can inspect the sequence directly.

I'm looking at the side view of the lich across frames k_00 through k_03, noticing the pose shifts — the arm moves from pointing down-left to horizontal, with the beam curving from the finger up toward the glowing ball near the head.

Continuing on, I'm tracking how the arm stays horizontal from k_04 through k_11 while the beam bends downward-left toward the snake target, and reconsidering whether the shift is recoil-driven or tied to how the aim point switches once the head travels far enough from the tip during the shoot animation.

That's actually consistent given the pitched perspective view — the arm angle isn't wrong, it's just the natural gesture as it rises from the aim. The recoil isn't clearly visible since frames are spaced 2 ticks apart and the arm keeps rising anyway; the curved beam at k_03 looks like a whip-crack where the finger flicks up horizontally while the head stays down-left. The beam colors across k_04-k_11 look good — thick, bright, cycling cyan/green/purple.

To really isolate the recoil effect, I want a debug toggle for recoil gain so I can compare enabled vs disabled runs side-by-side across the same post-fire frames, which would also make a clean evidence sheet. I should also fix the camera to a perpendicular side view centered on the arm.

The two runs on the same page aren't really comparable since the world state shifts between them, so I should instead run two separate page loads with identical scripts except for the gain setting, relying on the simulation being deterministic with a seeded rng.

Now I can compare the two clearly: with recoil on, the arm rises to horizontal and the beam bends along the finger like a whip before returning to a lowered position, while with recoil off the arm just points down steadily. The recoil looks decent but somewhat limited—mostly an arm raise with a slight elbow bend and hand flick, without much of a backward torso reaction.

Since the amount of force is subjective, I think a strength toggle would help him dial in the feel—LIGHT/MEDIUM/HEAVY plus OFF for comparison, bound to a key like X.

I'm also looking at the glowing point at the head, a combination of a small white mote and a larger tinted outer glow that appears when the head is moving fast, similar to a lens flare effect where it lands.

Next I want to check the CLOSE and ROOM views with the curve applied, review the K look variants, run the regression sweep, and then compile everything into the round page and stills—the burn spot only triggers past a certain threshold, which seems fine. Now let me set up the recoil presets.

Comparing recoil on vs off at the same moment shows the arm thrown to horizontal with the beam whipping along the finger before settling back. I'll add a recoil-strength key to gauge the amount, then check the three colour readings.

I'm noticing in the close camera view the beam forms a strong curved arc from the finger down to the snake near the egg, since the snake is close and the finger's upward recoil angle exaggerates the Bézier curve's bulge relative to the short travel distance.

This bothers me because beams should stay physically straight, so I'm weighing options: either limit the curve's deviation to a small angle by blending the control direction toward the straight path, or shorten the control-point distance so the bend concentrates near the finger as a subtle kink rather than a sweeping arc across the whole beam. The second approach seems better — a short 20-40 cm curve near the origin that then goes straight to the target keeps the beam anchored to the finger while reading as mostly straight.

Looking at the side-view comparisons across the streaming, held, and full color variants, the differences are subtle — the full variant just reads slightly more saturated and rainbow-like, but overall they're similar enough not to worry much. I also notice small dark tick marks along the beam's top edge at regular intervals, which I think are gaps at the joints between adjacent quad segments — since the curve changes direction, the edges of neighboring quads don't perfectly align, leaving little notches where the additive light doesn't fully cover, showing background through.

To fix these joint gaps I'm considering a proper miter join approach — passing each ribbon segment its previous and next points so the vertex shader can average adjacent directions and compute a blended screen-space normal at each joint, rather than leaving a visible seam.

I'm also checking whether the dark ticks I spotted in the rendered crop actually correspond to these segment joints, trying to line up pixel positions with the beam's segment spacing to confirm.

Now let's move forward and implement the miter join and the shortened control arm.

I'll fix the beam's rainbow-bow bending near the finger and eliminate the dark notches where curve segments join.

I'm tracing through the neighbor-pointer logic to confirm each piece's prev/next links are being set correctly relative to its neighbors, checking that the ordering of assignments doesn't clobber a value before it's used.

I'm checking the side view and confirming the beam bends slightly near the finger before going straight, with no notches, then verifying the close-camera row shows a short hook near the finger and the white core color near the beam's origin.

Now I'm planning a reduced verification sweep—beam alone and all-six cases at near/far distances in both chain modes, about 7 cases total—to run in the background while I catch any page errors and continue building the round page.

Since only one capture can run at a time, I'll hold off starting another render and instead use this time to update the fx.js header comments for style 4's pieces/joins, check the round 13 page bundling tool, and write the RECORD.md entry for round 18. I'm also planning the stills layout — the firing close sequence with recoil and beam, the three-colour side view, the room camera crop, and the recoil on/off comparison.

That last comparison is outdated since the curve/miter changes, so I'll need to redo it — first checking bundle.mjs usage and an earlier round's index.html to see how the game gets bundled into a page.

While the sweep runs, I'll check the fx.js header comment for style-4 and update it accordingly.

Editing fx.js is safe since the page's modules are already loaded and the server only serves files at load time. While waiting on the sweep, I'm drafting the RECORD.md round 18 entry and planning the handover stills — a sequence.png showing a close side view with recoil on versus off for comparison, plus a colours.png.

I also need a room.png with three crops of a fire sequence from the game view, and then I'll bundle the round page at rounds/18-prism-beam/index.html with those images. I'll hold off rendering until the sweep finishes, but I can start writing the RECORD entry now.

I still need to verify whether his hand actually turns prismatic from that light effect, something I'll check against a closer image later. While waiting for the sweep to finish, I'm keeping the pending items in mind: the prismatic beam in round 18 with its K colour and X recoil, plus the unresolved question of whether a C chain applies.

While waiting on the notification, I'm sketching out capture scripts for the stills — a recoil comparison image cropping and tiling frames from off/medium/heavy loads with labels, and a colours image capturing side close shots across the different K settings.

I can see the MEDIUM and HEAVY lift settings raise the arm and cause the beam to whip and bend at the finger, with frame 00 showing a glowing yellow burning-point ball at the head like a lens flare. Now I want to build a labelled recoil.png comparing OFF, MEDIUM, and HEAVY rows.

I'll write a small script using PIL to overlay text labels and a header caption on the frame stills, since my crop tool's filename-based labeling isn't quite clean enough — the default PIL font should be fine for this purpose. First let me look at the colors and hand captures.

Looking at the hand view in row 3, I'm checking whether the beam curve from finger to snake matches the expected bend magnitude given the distance — the formula for control point offset scales with beam length, so for a ~1.5m beam the bend should be fairly subtle, but the image seems to show a more pronounced curve than that calculation suggests.

I'm also comparing HELD vs STREAMING columns: held beams show a narrower hue range since the light field varies slowly, while streaming shows the full spectrum, which does distinguish them clearly. Then I'm questioning whether the hand should appear brightly lit given the point light's intensity and proximity — the physics suggests it should be quite bright, but the hand in the image looks fairly normal, so something (a distance cutoff or material property) might be limiting that effect.

I want to verify this directly rather than guess, so I'm planning to expose the light objects from the beam power so I can toggle the hand light's intensity to zero, re-render, and compare pixel brightness against the normal render to confirm whether the light is actually affecting the hand.

I'm comparing the hand with and without the beam's light — the lit version looks washed near-white rather than prismatic. That's because the arrival intensity is so massive at close range that it overwhelms the subtle hue-based recoloring, pushing the gem's effect toward pure brightness instead of showing distinct prism colors.

I need a softer falloff so the hand sits in a moderate range, not saturated: placing the light source out in front of the fingertip within the beam, slightly elevated, with a lower base intensity so the hand gets a visible gradient rather than blowing out, while the forearm further away dims naturally. I'm settling on positioning the light near the tip offset along the forward direction with a small intensity value, plus a colour tint blended from the beam's hue.

The beam was overpowering his hand instead of revealing the prismatic bone effect since it was too close and intense—I'll reposition it 15 cm out and dim it so the hand falls in the right light range.

I notice the lit hand has a subtle pinkish/lilac tint on the knuckles compared to unlit, matching the intended subtlety of the gem's glow. I'm also checking the beam detail near the fingertip, where it starts as a small white glow mote before extending outward.

Since the unlit and lit sparks share identical positions across frames, that consistency checks out. Now I need to prepare the final deliverable sheets for the prism-beam round — assembling index.html plus the recoil, colours, and room images, and re-rendering the recoil and colour captures since the hand light slightly altered their brightness (about seven quick renders total: three recoil, three colours, one room).

I'm setting up a script to generate the labeled sprite sheets, starting with the recoil sheet organized into OFF/MEDIUM/HEAVY rows with frame timing based on a 2-tick interval per frame.

I need to work out the crop and scale sizing so the frames fit legibly, then plan the colours.png sheet by camera angle and room.png as a 3x crop showing the game's room view at 0.05s intervals.

I notice the second row of tiles is missing time labels, so I want each tile to carry its own label rather than relying on a single row header, since stacking all ten frames in one row would be too wide. I'll restructure the grid to support per-tile labels instead of per-row ones.

Also double-checking the room crop math: at 180x160 cropped and scaled 1.5x, that's 270x240, so calling it "3x" is inaccurate — I should relabel it "1.5x crop." The lich sprite is barely visible in the dark corner but that's acceptable.

The title replace failed since grep found nothing, and the room.png width is wrong because the column list is empty, so I need to compute the width from the max row length instead. I also realize the escaped apostrophe in the title string needs to match exactly how it appears in the source file.

The heredoc is halving my backslashes, so `\\'` becomes `\'` and then Python strips it down to just `'`, which explains why my replace pattern never matched. I should switch to using the Edit tool directly instead of fighting with heredoc escaping.

I'm checking the frame timing math for the recoil animation and confirming it lines up correctly, then verifying the pierced snake's rainbow-fill-then-shatter effect works as intended.

I want to soften the caption wording about the beam light on his hand to be more accurate — something like "his hand and arm catch its light" rather than a stronger claim. Then I need to bundle the round with node's bundler and verify it loads properly through the headless screenshot tool, checking that it serves the directory correctly despite the extra PNG files present.

Let me check the page_room shot to make sure the bundled page renders correctly, verifying the HUD lines don't overlap at their respective positions.

The bundled page and HUD are working fine, so I'll hold off on committing since that happens at session end per the project convention. I just need to update the RECORD entry with the playable page path and the associated image assets.

I should add the verification result to RECORD round 18 (8 cases x 90s: 0 reached, 38 none), then update project_lich_dream_game.md with the session 3 round 18 line, and add the corresponding entry to the MEMORY.md index.

I'm drafting a concise handover message summarizing what changed and what needs judgment, making sure links use workspace-relative paths as required by the CLAUDE.md convention.

The round 18 link probably failed because it was relative to lich-survivors rather than workspace-relative like CLAUDE.md specifies — it should be `lich-survivors/rounds/18-prism-beam/index.html`. I should verify the files actually exist there.

I realize my links were relative to the wrong working directory since the workspace is actually Desktop/a327ex, so they pointed to a path that doesn't exist. I need to fix them with workspace-relative links, and double-check whether the colours.png was regenerated before or after I sent it, since the timestamps suggest it was created after the rebuild.

I'm locking in the defaults for recoil (heavy) and color (his colors, held), then working through a timing fix: he needs to point, pause, then attack, but the cast currently fires as soon as the head reaches the target or hits max aim time — I need to sync that with the arm's pointing weight ramp and its spring settling time.

Since the pointing logic lives in shared gesture code, this fix should really apply to all gestured powers (fire, lift, wind), not just the beam, though the beam is the only one reviewed so far — I'll lean toward applying it broadly for consistency.

For urgent cases I still want a beat, just shorter (like 0.1s), to preserve the sequence guarantee while keeping the response quick.

His second note: he doesn't want target-switching while a beam is live — the finger should stay locked on the first snake rather than sweeping to the next. So I'm dropping SWEEP mode entirely and keeping only BOUNCE for multi-target kills, where the chain hops snake to snake while the aim stays fixed on the first target, including how this interacts with the shatter timing after a snake is pierced.

Since the snake gets hidden and respawns elsewhere after being pierced, I need to make sure bounce segments don't follow the live spine position — otherwise the beam segment would jump to the snake's new spawn point. I'm fixing this by capturing the hit points as static Vector3 copies at burn-in time instead of referencing the live spine array.

With multiple targets it's still just one segment when there's only one. For the recoil kick during bounces, only the first bite (at the finger) should really push his hand since later hops happen away from him—so I'll keep the kick at 0.45 for the first hit only and skip or minimize kicks on subsequent hops.

For heavy recoil, I'm bumping the gain to 1.7 so the finger deviates more and the whip motion reads bigger, which fits the pose he chose. The point-wait-attack rhythm matters too: the recoil throws the arm off, and after the beat it settles so the kick reads cleanly against a stable pose.

I'm reworking the aim phase logic so the arm must actually finish arriving at its target before firing—checking the angle between the finger direction and the line from fingertip to target, plus requiring low angular speed, rather than just using the existing yaw-threshold and timer approach.

Since wrist correction keeps the finger nearly aligned with the target throughout the swing, finger-angle alone is a weak signal for "arrived." A better criterion is watching the arm spring's velocity components and confirming the spring is actually near its rest target, not just that the visible finger direction looks correct.

I'm considering tracking the fingertip's position relative to the lich's own root frame across ticks, since the caster might be moving while casting — so I'd want relative tip speed under some threshold (like 0.15 m/s) combined with pw >= 1 to call it "arrived," then trigger the beat. I'm planning to expose a helper like `lich.arm_settled(k)` that checks combined spring velocities against a threshold and confirms the spring's progress is essentially complete.

Working through the numbers for a 2.3 Hz, ζ 0.75 spring moving ~1.2 rad from rest, I estimate peak velocity around 7 rad/s and settling to under 0.3 rad/s taking roughly 0.4-0.5s, which combined with the 0.2s beat pushes total cast time to about 0.7-0.8s versus the current 0.3-0.55s — that's a meaningful slowdown that could break timing guarantees, so I'm thinking through a quicker "urgent" cast variant with a faster pw ramp, looser settle threshold, and shorter beat. I also need to account for moving targets like crawling snakes, since the arm has to continuously track rather than settle to a fixed point.

I should measure actual values in the harness, keep the existing head-turn criterion, and decide whether the target should freeze once targeted. I'm also reconsidering the AIM_MAX threshold for normal versus quick casts, and I'll need to re-verify the guarantee across all the combination cases since the new timing affects everything.

Given ~20 cases at roughly 90 seconds each, that's about 12 minutes total, which is acceptable to run in the background. I'm now planning to strip out the sweep mode entirely, keeping only bounce mode fixed, removing the sweep-related key, HUD line, and code branches since it's been ruled out, with bounce shooting each target sequentially from the previous hit point.

Now I need to check what happens when a snake finishes — I should look at how snakes.js handles taking, freeing, and completing a snake.

I realize the spine positions stay frozen during the respawn delay and only get rebuilt once it ends, so I should just store fixed hit points to avoid relying on that stale spine data.

Now I'm planning to simplify beam.js: dropping the SWEEP mode and just keeping BOUNCE, removing the C key toggle and its HUD line, and cleaning out the beam_mode references from GAME. I also want to change the default beam look to HELD and reorder the recoil and look option lists so HEAVY and HELD come first, while deciding whether to still let players cycle through the other rejected options as toggles.

For bites, I'm making the kick trigger only on the first hit, and for powers.js pointing logic, I want arrival to require both reaching the target and hitting the beat. I'm working out how to compute arm speed from the lich's spring state and building new aim arrival logic that checks point weight, arm speed thresholds, and time-on-target before declaring the arm has "arrived."

I'm reasoning through the timing constants—raising AIM_MAX to 1.3 and setting QUICK_MAX to 0.5—and confirming these same beat/arrival rules should govern the fire power's gesture too, since all cast actions share the point-wait-attack pattern. Now I want to instrument the code to log arm speed per tick during aim tracking so I can actually measure real values instead of guessing at thresholds.

I've locked in HEAVY recoil and HIS COLOURS, HELD as defaults, dropping sweep so the beam always bounces. Next I'll measure how long his arm takes to settle when pointing, so the beam fires only after that plus a beat.

Confirming the timing: at cast the arm is mid-swing at 3.3 rad/s, reaching arrival around tick 24-26 when speed drops below the threshold — so arrival lands roughly 0.4s after aim start, and adding a 0.2s beat puts the cast at about 0.6s.

For tracking a crawling snake, arm speed during hold sits around 0.25-0.3 from natural drift, so I want thresholds set at 0.7 for normal pointing and 1.5 for quick reactions. The normal beat is 0.2s versus 0.08s for the quick/urgent case (like a snake about to reach an egg), with corresponding max aim times of 1.2s and 0.45s — even urgent cases still get the full point-then-brief-beat sequence before attacking.

I'm now planning the implementation: adding an arm_speed function to lich.js that sums the velocity magnitudes of pitch, roll, and elevation, then updating the aim phase transition logic in powers.js to use these new thresholds.

Now I'm working on beam.js: bounce-only mechanics with fixed hit points, and kicking only on the first bite. I'm reordering the beam looks so HELD is the default, mapping each look index to its corresponding shader hue code (streaming, held, full rainbow).

Actually simpler: I'll keep the existing shader codes as-is and just default the look variable to held, cycling through the other states with the K key while the HUD reads from the BEAM_LOOKS array. I'm removing the sweep mechanic entirely, stripping out CHAIN_MODES and the mode variable, and restructuring the chain into simple shoot-dwell-shoot phases where each segment either curves from the tip or connects from the previous hit point. I'm also updating the aim and pose logic to follow the current target or fall back to the spine, and cleaning up main.js to drop the now-unused C key, HUD entry, and beam_mode import.

I'll apply the edits for the bounce-only rework, first checking the exact text around lines 100-180 and 205-300 before making the replacements.

I'm double-checking the edge case where extending during a fade-out mid-transition should still restart cleanly, and handling the case where resetting position pops the beam back. I'm also adding logic to track a "hold still" position, storing it on the point and initializing it during burn-in to match the goal.

I'm trying to figure out why the heredoc failed—checking whether an unmatched quote or a stray line is breaking the shell script's EOF terminator.

Since the python never actually ran due to the bash parse error, I should just switch to using the Write tool to create the file directly and then confirm nothing was accidentally modified by checking for MOVE_V in the source.

The `big` parameter still applies correctly since bounce mode makes all bites large now, and `N` remains valid in pierce_fx. I'm planning to test gesture capture timing between aim start and cast, then verify the bounce chain works when isolating a single high-power beam target before running the guarantee sweep.

I'm checking exactly when the arrival threshold of 0.7 gets crossed — tick 23 gives a sum around 0.83, already past it, while tick 24 drops to 0.56, so I need to pin down the precise crossing point rather than assume it's clean.

For the chain test, I want to verify the beam can hit multiple targets when several threats cluster near the egg, but I realize the internal chain data isn't exposed for testing. I'll add a way to expose the chain target count so I can capture evidence — timing frames from aim to fire, a bounce chain from a close camera angle, plus a broader sweep of guarantee test cases.

Firing now happens 0.62s after pointing starts, with the arm settling and holding still for 0.2s before firing at a much slower 0.17 rad/s (down from ~5). Next I'll capture a multi-snake bounce along with the point → beat → fire sequence.

I need to capture the camera direction before the arm arrives, since the aim point is known at aim start. I'll compute the view from the lich's shoulder to the target point once motion begins, then hold that direction fixed for the sequence, capturing frames every 3 ticks across 60 ticks for 20 total frames.

Actually, spanning from aim start through 0.3s after firing gives roughly 55 ticks total, so I'll switch to sampling every 4 ticks for 14 frames instead, and label each frame with its phase (aim or hold) pulled from the eval results into the sheet labels.

I'm timing the arm's rise, arrival, pause, and firing kick with the whipping beam. Then I'm mapping the bounce path: finger to the first snake, then to a second, then a long third hop crossing far across the room toward the bottom right.

Now I'm setting up a background sweep of 20 test cases covering each power alone or combined, near and far, since the previous batch of 8 took several minutes and this larger run will take longer.

Both approaches work correctly—the arm raises, holds, then fires with a heavy kick, and finger tracking stays on the first snake during bounces. Since pointing now takes ~0.3s longer, affecting all pointed power timings, I'm re-running the full 20-case guarantee sweep to verify.

While that runs, I'll update RECORD.md with the round 18 verdict and start the round 19 entry, plus update memory.

While waiting I'm drafting the round 19 sheet layout: 15 frames labeled with elapsed time and phase, computing each shot's tick as 1+4k giving t=(1+4k)/60, distinguishing the ten aim frames from the five hold frames, and marking the first hold frame as "POINTING"/"FIRES" along with the beat arrival frames.

For chain.png I'm laying out 10 frames from camera 2, spaced 4 ticks apart, with the beam alone taking 3 frames.

Since the r19c/r19d captures already match the current code behavior, they're solid evidence, so I can go ahead and build the bundle now since that's just reading files rather than rendering.

I'm noticing a slight timing mismatch — the cast registers at tick 37 (+0.62s) but the visual beam doesn't actually appear until the next frame at +0.68s, so the beat marker and the fired effect are off by about one tick.

The chain sequence itself looks right: the lich aims down-left at the first snake, with a pink segment from his hand to the target and shorter pink/white segments following for subsequent hops. I need to wait for the sweep to finish before I can capture or render anything else, since only one capture can run at a time.

I need to lower the beat to 0.15s for beam/default gestures, and also address the balance issue where lens gets used far more than beams when both are active — I should think about a fairness mechanism, like tracking usage counts per power and favoring whichever has been used least, so all powers stay roughly equally utilized while still keeping the snakes at bay.

Right now gestured powers rotate via "least recently used," but the lens runs independently on its own cooldown timer, so it fires whenever ready regardless of what the gestured power is doing — I need a unified scheduler that treats all powers together. The tricky part is leakage, which is passive and continuous rather than a discrete cast, so I'll need to measure it by kills instead of cast count, while measuring the other powers by casts, and see if I can get them into a comparable range before tuning further.

For fire, the aim delay stays quick at its usual short beat. For lift, multiple nearby snakes should get grouped and lifted together, with his arm tracking upward as they rise and only dropping once they're killed off in the burst. The lift explosion needs to feel more gory and detailed than it currently does — better meat chunks with visible flesh and maybe bone fragments, blood streaks and splatter decals on the ground, trailing gibs, and a lingering blood pool — though since "gory" is a bit of a new visual direction, I should probably gather some reference points before committing to the exact look.

Given he's given a clear enough direction and doesn't have strong prior decisions ranking specific gore styles, I think the right move is to build a couple of intensity variants as a toggle, similar to how other rounds handle style options, rather than committing to one single realistic-vs-stylized choice outright.

I'm thinking through snake anatomy references for realism — scales on the outside, red muscle and pink flesh inside, ribs and vertebrae exposed, entrails, blood spray and pooling — and mapping that onto a three.js implementation using instanced meshes for skin chunks, bone pieces, and gib shapes with scale texturing.

I'll add physics-driven gibs with bounce and rotation, blood droplet trails while airborne, and splatter decals where they land, plus a fading blood pool decal at the burst center — combining point sprites for droplets, velocity-aligned streaks, and projected splat quads on the floor.

For entrails I'm weighing verlet-chain rope pieces versus simpler elongated strand gibs, and considering how wetness/specular highlights will help blood read properly against the dark cave lighting. Before diving in, I want to check lift.js and the snake's existing scale materials, then plan the director fairness system so power usage rotates evenly based on least-used ready powers.

Leakage happens automatically and its kill count depends heavily on proximity to the lich, so I should track it separately from the discrete powers rather than force it into the same fairness measurement. Now I want to give each power its own beat value, defaulting to 0.15 but overriding fire to 0.05, by adding a per-power beat property that falls back to the default. Next I'll look at the lift group code to understand how the arm follows the aim point during a hold.

I'm thinking about how to measure usage—tracking casts per power and attributing kills to whichever effect actually took down the snake, whether that's lift, pierce, cut, fire, or dissolve via leakage. I'll set up a simple counts map in powers.js to tally casts per power alongside lens casts, and figure out how to count leakage-caused snake deaths.

Leakage is continuous and ambient rather than a discrete cast, so I'll treat fire, lift, wind, beam, and lens as the rotating powers while still tracking leakage kills separately. I want to add a per-power usage counter that tracks both explicit casts and snakes consumed.

I'm planning to add counters for uses and takes, plus track a dissolved count for leaked snakes, then run measurement combos across different tool pairings at near and far ranges for 90 seconds each to establish baseline usage before making any fairness adjustments.

I notice `uses` tracks snakes.dissolved which isn't reset by reset_uses, so I need to record dissolved at start and diff it myself. I'll set up the measurement script to compute `took` and `uses` diffs across several 90-second test cases (near and far lich, combinations of beam/fire/lift/lens/wind, plus all six together) to isolate resource leakage per configuration.

While that render runs, I can plan the fairness scheduler and lift/gore implementation in parallel since coding doesn't require rendering. I'm designing a unified scheduler over the discrete powers—fire, lift, wind, beam, lens—each keeping its own scaled cooldown, with leakage treated as a continuous ambient effect and special handling triggered whenever a threat is present.

I'm working through candidate selection among ready powers, picking whichever has the lowest recent usage score to keep things balanced, with an urgent backstop that overrides fairness when threats pile up and the gesture channel is tied up. I'm now leaning toward a decayed "usage debt" model where each power accrues a score that decays over time, and a power can only act on non-urgent threats if its debt isn't meaningfully ahead of the others.

I'm reasoning through why the lens tends to see more usage than gestured powers — since it runs in parallel and doesn't have to wait for the shared gesture channel, its effective cycle time ends up shorter, giving it more opportunities per unit time even with a similar cooldown value.

With the "not ahead by more than one" fairness rule, usage should equalize across casts as long as each power can keep pace, treating a single cast as one "use" regardless of how many targets it hits. I'm also thinking through the edge case where fairness holds back a ready lens while the gesture channel is occupied, letting a threat creep into urgent range and forcing the soonest-ready gestured power to fire instead.

For the tiebreaker mechanics, I'm defining a sliding usage-count score over the last 40 seconds, where a power is allowed to act if its use-count is at or below the minimum among the others, effectively forcing strict round-robin alternation between two powers, but adding an escape hatch so any ready power can override fairness when an urgent, unclaimed threat exists and the gesture channel is tied up.

I'm now checking whether strict alternation is too rigid — if a power has a long cooldown, threats could stack up waiting for it, but the urgent-threat override should resolve that. I'm considering loosening the rule with a slack of 1, letting a power get one use ahead before the strict cap kicks back in, and walking through short sequences to confirm this still preserves rough fairness without starving either power.

I'll simplify by tracking counts cumulatively since the last time the power set changed, resetting whenever a power is toggled or reassigned, so the fairness comparison stays bounded and stable.

Among eligible candidates, I'll pick by fewest fair count, then least recently used. The lens gets priority whenever its count is lowest, firing in parallel with the gesture channel when possible; but when the gesture channel is busy and it's actually a gestured power's turn, the lens has to wait, making the gestured cycle the throughput bottleneck.

I also need an urgent backstop: threats within 2.6 m and unengaged should trigger a quick gestured response if the channel is idle, or wait if the channel is mid-aim. I'm considering letting the lens break fairness entirely for urgent threats, firing normally (not the instant "quick" variant) even out of turn, though that adds complexity around timing.

A normal lens cut takes about 1.2-1.5 seconds, but an urgent threat 2.6 m out closes the distance to the target radius in roughly 1.25 seconds, so a normal lens is too slow — this confirms I need the quick-fire variant specifically for urgent cases when the gesture channel is occupied. Urgent casts should still count toward the fairness balance so the system self-corrects over time.

I'm also setting different beat timings per power type, with fire notably faster than the rest, and thinking through how to group multiple nearby snakes so they get lifted together in a single cast.

For the lift mechanic, I want the arm to track the lifted snakes' center as they rise until bursting, then lower afterward — so I'm defining how the lift stays "busy" and computes its aim point as the average midpoint of the currently lifted snakes, feeding into the generic hold logic.

I'm worried though: during the full lift sequence (rise, hold, swell — about 1.34s total), any urgent snakes that show up can't be channeled since the lift isn't extendable, which risks breaking the guarantee that urgent threats always get handled in time. I should consider adding an extend option to the lift so it can accommodate multiple snakes entering the danger zone during that window.

Now I'm sketching the burst implementation itself: the pre-burst swell with trembling and stretched skin, then the actual explosion producing varied flesh chunks — two-tone skin pieces, glossy dark red meat, and off-white bone fragments like ribs.

Each chunk type gets its own instanced mesh with a distinct shape (curved skin shards, distorted meat lumps, thin bone cylinders, knobbly vertebrae) plus per-instance color variation. As chunks fly out they'll spin, bounce, trail blood droplets, and leave splat decals on landing, while a few entrail strands get thrown out as verlet-simulated ribbons for extra gore.

Ribbons turn out to use additive blending though, which would make blood glow instead of look dark and wet -- so I need a non-additive alternative, maybe a chain of small instanced meat-bead spheres following verlet constraints to read as intestines. For blood spray itself I'm thinking cone bursts of dark red alpha sprites with a slight bright core to help them read against dark cave backgrounds, though orienting sprites along velocity to get streak shapes is tricky without screen-space velocity computation.

I want to pass a screen-space direction per particle so the fragment shader can rotate and stretch gl_PointCoord into an elongated streak -- that means a new streak pool with an added velocity attribute. I also want floor decals: a pool of flat rotated quads with a procedurally generated splatter texture (canvas-drawn splat variants), dark red, using normal blending and polygon offset so they sit correctly on the ground.

Since the floor is uneven and rocky, I'll keep the decal quads small and placed slightly above center to avoid clipping into bumps -- that seems acceptable. I'm reconsidering using MeshStandardMaterial with the splat as an alpha map so the decals are properly lit and read wet, fading over 6-8 seconds before drying darker or vanishing.

I'm dropping the idea of a pale flash accompanying the burst since it reads as a cheap effect, and there's no sound involved. For the snake's head, I want it to survive as a recognizable chunk that detaches intact rather than disintegrating.

Rather than trying to gib the head separately, I'm thinking the better approach is to split the whole snake tube mesh into several segments along its length -- including the head and tail ends -- and turn each segment into its own rigid body with capped, reddened open ends using the snake's actual skin texture. That would read as genuine torn snake pieces rather than generic gore lumps, supplemented with meat bits, bone fragments, and blood.

I'm sketching the implementation: I'd copy the vertex positions, normals, UVs, and custom shader attributes (like aBurn) for a given ring range into a new buffer geometry, pool a set of preallocated gib meshes sized for the max segment span, transform each rigidly per tick, and cap the torn ends with a red fan of triangles to suggest exposed flesh.

I'm also thinking about varying shred size along the body — smaller bits near the midsection where it swelled, bigger chunks at the head and tail. Since the current gore looks too cheap, I want to lean into detail here, and I'm treating this as legitimate fictional violent game content.

I'll proceed with building a richer attempt rather than pausing to gather references first, maybe offering a gore-intensity toggle to compare levels. My plan: implement fairness for usage results, adjust beat timing and fire rate, add the lift group with arm-follow and extension, build the gore burst, then verify guarantees and present a usage sweep table as evidence.

Let me check the usage run to confirm the sequencing before finalizing.

Once the usage measurement finishes, I'll implement fair-use turn rotation for attacks (with priority for snakes near the egg), set timing to 0.15s beats and 0.05s for fire, add lift behavior that follows targets up, and build the burst effect with torn body pieces, meat, bone, and blood spray/pooling.

I'm seeing the imbalance clearly now — lens dominates with 31 kills while beam gets 0, because lens engages much earlier at 6m and picks off targets before beam's 3.4m range even comes into play. The fix is the unified fair scheduler I planned, and I need to reconsider the engage distances too.

For the tick() logic in powers.js, I'm tracking usage counts per power and giving priority to whichever is least recently used, with the lens taking its turn at 6m and gestured powers taking theirs at 3.4m. I'm working through edge cases: if it's a gestured power's turn but the lens has no ready option, urgency should let gestured powers act early — but I need to check what happens when it's specifically the lens's turn and its own cooldown isn't ready yet.

I want "ready" to mean cooldown-cleared rather than truly idle, since a power occupied by a channeled action (like the beam) shouldn't block others from taking their turn just because it's technically busy.

Simpler rule: a fires when its fairness value is the minimum among active discretes, but I should treat powers with cooldown remaining beyond 1.5s as non-blocking since they're too far from ready. With strict lens/beam alternation, the beam's channel time effectively blocks the lens from acting in parallel, so throughput ends up mostly serial rather than truly concurrent.

I want urgent unclaimed threats to bypass fairness entirely so nothing waits unnecessarily, while continuous leakage stays untouched since it's passive and always-on rather than something to balance via turns. Now I'm writing the tick logic that filters active powers excluding the leak source...

Writing turn logic...

For urgent lens handling, I'm reasoning through when the gesture already covers the threatening snake versus when lens should act independently — filtering out urgent snakes already claimed as gesture targets so lens only rushes the ones the gesture won't reach.

Now I'm working through supporting details: fair counts should reset whenever the active power set changes, lens capacity treats multiple casts as one use, and each power has its own beat timing (fire fastest at 0.05, default at 0.15, quick variant even tighter). I'm moving into the lift power's cast logic, starting with how it gathers neighboring targets around each selected one.

Clamping the arm pitch so it stays pointing forward-up rather than overextending. After burst, the hold continues briefly before lowering, matching the "only go back down once killed" rule; the fire beat still uses the look-then-catch pattern from before. Now I want to check the snake mesh construction code to figure out how to build segment gibs for the gore effect.

The lens dominates casts because it engages at 6 m versus 3.4 m for pointed powers, which otherwise share turns evenly. I'll build a shared rotation to fix this imbalance.

Let me check the mesh geometry generation code, particularly how UV coordinates and index buffers are constructed.

I'm designing a gore module that splits the snake's tube geometry at the burst point into separate body pieces, with rings near the impact center destroyed into meat while outer rings form remaining fragments extending outward from the head.

For each torn piece, I'm planning realistic cross-section caps—vertex-colored flesh circles with a white spine dot and dark cavity center—using a wet MeshStandardMaterial, plus jittered ragged edges to make the torn ends look shredded.

Given the piece meshes are only a handful of pixels wide on screen, I decide to skip most of the raggedness detail and focus instead on physics: pooling 12 rigid-body pieces with gravity, ground collision at the cave floor, bounce-friction settling, and small random impulses to simulate brief twitching before they fade and sink into the ground like other corpses over a few seconds. I'm also sketching out an instanced mesh of scattered meat chunks using noisy dark-red glossy dodecahedra with per-instance color variation.

I'm planning the bone fragments as instanced torus arcs for ribs and small cubes for vertebrae, plus entrails made from verlet chains rendered with my own lightweight tube-builder like I used for the snakes.

For blood I'm designing a streak-sprite pool where each particle's world velocity gets projected into screen space in the vertex shader, stretching the point size along its motion direction to create realistic spray trails.

I'm also planning floor decals: a pool of splat quads using a procedurally generated texture atlas of blood pool variants, set up with proper depth and polygon offset so they render as wet-looking stains that fade out over several seconds, spawned via a landing callback when streak particles hit the ground.

I'm considering extra touches like blood dripping from the snake's mouth before it bursts, but deciding to skip that and the belly-swell glow for now. No sound effects planned, the pop flash is confirmed removed, and I'm weighing whether a subtle camera shake fits the game's fixed RE-style camera setup.

Since he wants the effect to look less cheap, I'm thinking about whether a toggle to compare against the old burst would help, but decide against adding a gore toggle since the previous rounds are already preserved for comparison. Performance-wise, headless WebGL should still run fine, and I'm sizing up how the debris will read at actual scale on screen -- small chunks, tiny meat bits, and blood decal size from the room camera's perspective.

Now I'm starting to sketch out the gore module, setting up a create_gore function that takes the scene, cave, and snake material to build the burst effect, with a burst function to trigger the explosion and an update loop to animate it over time.

I'm working out how to slice the snake's tube geometry into pieces using its existing ring/side vertex layout, then cap each severed end with a fan mesh whose center is pulled slightly inward to fake a concave wound.

For the cap coloring, I'll keep it simple: dark red at the center, red toward the rim, and one vertex tinted white near the back to hint at the spine, since detail beyond that won't read clearly at typical camera distance.

I'm working out how to fold cap triangles into the same geometry as a second material group, so the tube uses the snake shader while caps get a separate flesh material with vertex colors — the snake material will just ignore that color attribute. Now I'm sizing the vertex buffer to accommodate the maximum ring count plus the cap geometry (center plus inner and rim rings).

Caps need their own vertices rather than reusing the tube's rim, since cap normals point along the axis instead of radially, so I'm allocating separate rim, inner, and center verts per cap. I'm preallocating a Uint16Array for indices covering both the tube quads and the cap fan/quad triangles, then setting geometry groups to point at the right index ranges — and for motion, I plan to store local positions relative to the centroid once and just update the mesh's position and quaternion each tick.

For physics, I'll approximate ground collision by sampling a few points on each piece, checking penetration against ground height, and applying a bounce with damped velocity plus friction and angular damping — simplified but should read fine visually. Pieces will rest for a few seconds, then sink and fade out over roughly 6 seconds total lifetime, and I'm planning meat bits as an instanced icosahedron mesh with baked vertex noise and per-instance coloring.

Now I'm sizing out the debris pools — meat, bones, pieces, strands, decals — and designing bone shapes like thin torus ribs and small dodecahedron vertebrae with an ivory material, reusing the same instanced debris physics class. For entrails I'm setting up a verlet-simulated chain of nodes to get a soft, draping strand effect.

For entrails I'm deciding to permanently attach node 0 to a torn piece's cap so the guts drag along with the flying body part, which reads as more realistic. Now I'm planning a separate streak pool inside gore.js for blood that lands and spawns decals on the floor.

For decals, I'm working out whether to use instanced planes with an atlas texture and per-instance UV offsets, or simplify by using four separate instanced meshes for four splat variants, each with per-instance fading via instance color.

For fading, since blood shouldn't visibly shrink, I'll instead sink the decal beneath the floor over its lifespan so it gets hidden by depth testing—looking like it's soaking into uneven ground rather than disappearing abruptly.

I'm also sketching the splat texture itself: a 128x128 canvas with a noisy main blob, scattered satellite droplets, soft alpha edges, and a dark red base color with slight variation, paired with low roughness for a wet sheen.

Now I'm working out the burst effect: a quick radial splash of streaks plus a downward rain of droplets falling from the snake's burst point to the floor below, creating a secondary splatter pattern. I'm planning how this hooks into the lift's burst trigger, referencing the snake's tube geometry and material so the gore system can spawn from the right source.

I'm figuring out which ring segments turn into gore pieces versus shredded material, computing arc lengths along the swollen tube to decide cut points — the middle region near the impact shreds entirely while the head and tail sides break into irregular chunks roughly 0.35 to 0.7 meters long, each capped at a maximum ring count.

Since ring spacing is much denser near the head, the first piece there ends up spanning too many rings, so I'm bumping the max ring cap up to accommodate it. Now I need to work out how fast each piece gets thrown outward from the center of the blast.

Meat fragments get radial velocities outward from the spine, speeds around 2-5. I'm also tweaking the burst swell timing to feel more like a pressure buildup before the pop, stretching it slightly with a tremble effect. Next I'll write out the fairness, beat, and lift logic in powers.js before tackling the gore effects.

I notice lift.update() isn't being called in tick since lift has an empty update method, but I'll call it anyway just to be safe. Now let me write the edits to powers.js.

I'm checking whether the busy-hand quick lens logic breaks fairness elsewhere—it only fires on urgent cases, so it stays balanced with other powers getting turns. I'm also confirming the lens-turn requirement works correctly under low-computation conditions before checking edge cases.

Now I'm rewriting lift.js from scratch, handling grouping, following, extending, and gore effects.

I'm checking the lift_fx delay logic — confirming the snake stays still during the brief delay window, which is fine since it's only 0.08s, and now I'm looking at whether the held list gets properly reset when a previous lift's snakes are still active at cast time.

I need to call lift.update() in the tick loop before the busy check to prune burst snakes. Now I'm starting on gore.js, setting up the module that turns a burst snake into gore — importing THREE and the smoothstep utility, and defining materials for snake skin, flesh, and meat bits with vertex colors and dynamic GI.

I'm working out materials for bone, guts, and blood decals, and now I'm checking whether gi_dynamic — which samples lighting by world position — properly accounts for instance transforms when applied to instanced meshes, since it likely needs to factor in the instance matrix rather than just the model matrix.

I'm noting that instancing works and each material needs its own onBeforeCompile call since uniforms mutate per material. For the snake skin material, I need the geometry to include a custom aBurn attribute so the vertex shader can read it for the burn effect.

Now I'm planning gore.js: a pool of 16 piece meshes, each with geometry buffers for position, normal, uv, aBurn, and color, paired with skin/flesh materials assigned via groups. I'm working out how to build each piece by copying vertex data from the source snake mesh, closing torn ends with flesh caps versus natural snout/tail tips with skin material, and computing centroids from the source position and normal attributes.

Writing torn-end cap geometry...

Now I'm working out the rigid body physics for each severed piece: tracking position, velocity, and rotation via angular velocity, with sample points at each ring for ground collision, applying gravity and checking against the terrain height function with a radius offset.

On collision, I bounce with damping on velocity and angular velocity, settling into a rest state once slow enough, and after ~4.5s of lifetime the piece sinks and vanishes over 1.5s. I'm also adding dripping blood particles from the torn ends while airborne, a splat decal on first ground impact, and a decaying twitch effect using small random angular kicks for about 1.6s after landing to sell the gruesome detail.

Now I'm designing the debris system with instanced meshes for meat chunks (jittered icosahedrons for a lumpy look), bone ribs (torus geometry), and vertebrae (dodecahedrons), each pooled with per-instance position, velocity, rotation, scale, life, and color data, reusing similar physics to the chunk pool but with occasional blood droplet spawning for the meat pieces.

For guts, I'm setting up a pool of strands using verlet-integrated node chains built into tube meshes, with gravity, damping, ground collision, and a limited lifespan before sinking, plus a streak-based particle system for blood oriented along velocity vectors.

For the particles landing, I'm having them spawn ground decals on a probability chance before dying off, then setting up four decal texture variants pooled into instanced meshes that fade by sinking slightly below the ground surface over their lifetime.

Pool decals grow from 0.3 to 1.0 scale over 1.5 seconds to simulate blood pooling, updating instance matrices each tick for active ones. For the splat texture itself, I'm generating a canvas with a red-alpha main blob made of overlapping circles plus noise, with smaller satellite circles and an elongated splash variant that rotates to match velocity direction for directional splats.

Now I'm setting up the mist puff effect and starting to define the burst sequence logic, computing arc positions and choosing a shred zone around the midpoint.

Still working out piece velocities and spawn logic...

Now I'm sketching guts strands anchored to torn caps, blood jets combining streak droplets, spherical spray, and falling rain droplets that splat below, plus a growing floor pool decal and mist puffs, while considering whether to reuse existing floor dust.

Then I trace the build order in snakes.js: the fx tick runs before the mesh build each frame, so burst positions come from the prior frame's geometry, and once the burst fires the original mesh gets hidden so the exploded pieces take over visually.

Since all the pieces share the snake material, rendering the extra meshes stays cheap. I also note the cave module exposes ground_y(x, z) for terrain height lookups, then move on to start writing gore.js.

I spot a bug in the scrap material setup — I referenced a nonsensical fallback instead of properly creating a lit material beforehand. I should fix this by building a proper two-toned scrap material, maybe dark olive scales outside with a contrasting inner color.

Considering reusing the snake's own material for scraps since it already handles scale texture and instancing, but that material is front-side only, which would cause flickering when scraps tumble and show their backs — so I'll stick with a dedicated double-sided olive material. I also need to double check that the spine placement logic correctly identifies the back side of the ring, and that the ring-closing function correctly maps local ring indices and tip vertices back to their source geometry.

Fixing the winding order for the snout and tail cap triangles, then reconciling my triangle indices with the source's tube quad winding to make sure normals face outward consistently.

I'm also double-checking the tip vertex indexing and normals, the piece variable naming in the guts update logic, and the verlet integration step where gravity is applied via GRAV*dt*dt.

Checking the burst function's local end positions, the droplet pool size of 900, and thinking through whether the blood sprite's unlit dark-red color will render correctly against the HDR linear world target.

Checking the decal texture's alpha channel setup and plane geometry orientation, then verifying instanced mesh rendering order and inactive decal handling default to zero scale correctly. I'm also confirming the debris pool's instance color update logic is wired properly.

Now I'm cleaning up that ugly comma-expression code and verifying the snake material export gets added to the module's return object. I'm also double-checking the index and vertex buffer sizing math for tube pieces with closes and wounds, confirming a piece can't have both simultaneously, and reviewing ground contact sampling radius.

For throw_piece, I'm clamping the launch height and normalizing so distant tail pieces still get consistent speed. The head piece won't carry the eye meshes since those are separate — deciding that's a minor omission worth skipping for now, while confirming the lift arc's mid-air starting positions work correctly for the burst animation. I still need to make sure the gore instance gets created and wired into the lift function through the context object in main.js.

I confirmed the snake material setup in create_snakes looks correct. Now I want to test a lift burst close-up: enable only the lift ability, position the lich near an egg, wait for the lift cast to trigger, then zoom the view in on the lifted snake to watch the burst frame by frame, starting by grabbing the snake's mid-position as the view target.

The effect works overall, with torn red-capped pieces flying and blood streaks trailing, but the red caps look too bright and cartoonish — I should dial back the saturation on the wound discs and darken the muscle tone underneath for a more glossy, realistic look.

The blood streaks also read as thin, artificial vertical "rain" lines rather than natural droplets, so I'm shortening the motion-blur streak duration and sizing the drops bigger so they read as small blobs instead of needles. I also want to check whether meat bits and gut strands are actually visible at this scale, and pull up a closer, higher-res frame of the burst moment to judge it properly.

The wound caps look too much like flat, cartoonish red discs with a bright mushroom-cap highlight. I want to fix this by making the flesh bulge outward convexly, like it's being pushed out by internal pressure, with a jagged, torn, irregular rim instead of a perfect circle.

I'm also rethinking the layered ring structure — rim, mid, and center — with darker, more varied muscle tones and a shredded, tattered look rather than a flat fan shape, and lowering the overall cap size since it's currently oversized relative to the wound.

For the blood streaks, they're too many, too bright, and way too long — my math shows they're stretching to over 20 pixels when they should look like short 1-2cm droplets, so I need to shorten the falling-motion factor to bring them down to a more realistic 6-pixel length.

The gut strand looks too stiff and stick-like, so I want to make it shorter, thicker, and lumpier with more slack and wobble, plus a darker pink-grey tone instead of the current straight, pink stretched line — and I'm satisfied the small meat blobs already look fine.

The rib arcs read too bright and bone-like, so I'll warm them toward a darker grey-ivory tone; the floor blood spots and red mist look okay as-is, and the snake-scale pieces already look convincing. Now I'm adjusting the wound caps — nudging the jittered rim ring and pushing the mid ring outward along the axis to sell the burst better.

Now I'm working out the index buffer sizing between the rim, flesh, inner, and center rings, confirming it fits within the allocated space, and updating the total vertex count to account for the extra cap ring.

This works end to end, but three details read cheap: the wounds look like flat red discs, the blood reads as straight needles, and the gut strand is a plain stick. I'm fixing these now.

The pieces flying toward the camera now look big and close, with wounds reading as torn red flesh and blood as small spray-like dots—an improvement. But the camera placement makes it hard to judge properly, so I need to check the room camera and a closer view instead.

I also spot b_08 with a vertical red stick hanging off a piece, reading like a dangling gut strand, which works. Now I want to run proper evidence captures: the room camera, a closer camera, and a mid-distance inspection shot, while also checking the lift group and arm follow with the lich near the egg.

I'm noticing the arm briefly holds at frame 00, then drops through 01-03 before pointing again in 04-09, with a faintly lifted snake visible behind the egg. That pattern suggests the first hold ended quickly because the held list was empty, so the logic moved on to a lift/take action instead.

Since the snake being targeted might already be claimed elsewhere, I wonder if the take fails when the target isn't free. Looking closer, the lifted snake seems to sit at the back-right behind the egg, and by frame 05+ the arm points toward it. It's hard to be certain at this resolution though, so I should zoom into a larger crop around the lich for frames 0-9 to see what's really happening.

This log is from the room run since the second run overwrote log.json. The phase stays at 'hold' for all 98 ticks, which is 1.6 seconds, matching the lift channel's 1.4 second duration plus the hold period.

The arm correctly tracks the lifted snake rising into the dark, with the egg staying visible behind it. Since only one snake is lifted here with no neighbors, I want to test a scenario with multiple snakes close together to see how group lifting behaves, though manipulating the trail-based snake structures directly is tricky, so I'll try running lift-only for longer to find a natural case instead.

I'm tracking the two snakes rising together near the right edge before their burst at frame 11, plus keeping the gore consistent—leftover pieces and blood near the egg, red wound caps visible on the fallen pieces, and blood smears in the dark area on the left.

Now I'm shifting focus to setting up the room camera shot.

From the room camera, the lifted snake behind the egg is obscured in the dark, so the burst just reads as a red spray, which is fine since it happened on the dark far side. Now I need to run fairness verification and the guarantee sweep — rerunning the 12-case usage script across near/far combos, then the 20-case guarantee sweep.

Both are needed since the usage script covers pairs, five-combos, and all six, while the 20-case sweep covers singles; I'll run them sequentially in the background, starting with the usage script (~7 min then ~12 min).

Confirmed the group lift works as intended—neighboring snakes rise together, stay attached to his arm, and burst together, while earlier bursts' debris remains on the floor around the egg. Now re-measuring usage with the shared rotation and the guarantee.

While I wait, I'm sketching out the evidence sheets for round 20: a usage table for chat, a gore.png sequence with the inspection camera repositioned for better framing of the aftermath, and a lift.png showing the group lift.

For timing I should measure the actual fire cast time and beam cast time after the usage run rather than guess, and I'm noting that the `powers()` call resets fairness correctly each case since `set()` refreshes it when values change.

There's a big improvement in pair balance, but lens still runs about twice as high as the others in the five/six configurations. I'm realizing that's because gestured powers all funnel through one hand, making that channel the bottleneck, and my `low` computation may be miscounting busy-hand cases where a gestured power's next timing falls under the threshold anyway.

I think the real mechanism is that whenever the hand is tied up, urgent threats get resolved through the lens's quick path since it's the only thing free to act, which naturally inflates its usage. To balance things properly I need to think in terms of throughput: with several gestured powers sharing one hand at roughly a 2-second cycle each, the lens being parallel means it needs a cap tied to the hand's overall cast rate divided among the gestured powers, not just a simple use-count comparison.

One fix would be to enforce strict rotation on the lens too, so it only fires when it's genuinely the lowest-count option even during urgent situations, and instead let other channeled powers extend to absorb urgent snakes when the hand is occupied rather than defaulting to the lens.

A better approach might be speeding up the hand cycle itself when several powers are active — chaining gestures so the arm moves directly from one aim to the next without fully resetting, and shortening hold times when other targets are waiting. This raises throughput naturally without breaking the "equal usage" balance.

Looking at the actual cadence: near the egg it's about one cast every two seconds, but the gesture cycle for a lift power alone runs close to 1.4 seconds just for the rise-hold-swell sequence, plus lowering time — so the timing math needs to account for how long each gesture type actually takes to complete.

With 26 casts logged in 90 seconds, the hand was clearly sitting idle between turns while cooldowns (roughly 4-5 seconds per power) weren't the bottleneck — something else, likely the rotation rule giving the lens priority, was eating into the hand's available casting windows.

I'm working out a way to shorten the hold time when a threat is waiting, so the hand can skip straight into the next gesture instead of fully lowering first — chaining directly from the current pointing position into the new aim.

I'm also reconsidering when the quick lens rescue is actually needed: since beam/lift channels can extend on their own, rescue should only trigger if the hand is locked into aim on a different target and the urgent threat is very close (under 2.0m), otherwise the hand naturally frees up between gestures.

I should count lens casts as normal versus quick to double-check the measurements, and compare lift versus lens coverage (18 vs 26) — since the lift channel is long, the lens can pick up the slack once things chain together better. Time to implement this and re-measure.

Pairs are nearly balanced now, though with five or six powers lens usage still doubles beam usage since all pointed powers share one overworked hand, forcing emergency lens fills. I'm fixing this by pointing directly from one snake to the next without lowering the arm between casts, and reserving the emergency lens for snakes truly about to reach the egg.

I'm planning to extract the gesture-picking logic from the idle branch into a reusable `next_gesture(allow_quick)` function, then reuse it across idle, hold (post-HOLD_MIN, non-channel), and lower cases to avoid duplication.

I'm working through how `start_gesture` interacts with arm switching — since the target point's arm can change, the old arm's weight drops immediately while springs smooth the transition, though stiffness might briefly jump when the arm switches sides.

For the rescue lens, I'm restricting it to lone targets or ones close to the egg during the aim phase that aren't already in the target list, reasoning that other phases (hold, lower, channel) already naturally resolve through idle/quick gestures, so rescue logic is really only needed when busy aiming elsewhere. I'll also add a separate counter to track quick lens usage for testing.

I'm checking the gesture state transitions—making sure the hold phase during FIRE properly chains after 0.2s, and that the lower phase keeps retrying try_gesture on each tick since the hold-to-lower transition only fires when no gesture is available.

Now I need to update the usage script to track quick_lens, so I'll patch the r20_usage eval JSON to include the diff for G.powers.quick_lens.

While the run continues, I'm planning the gore evidence capture: widening the inspection camera and setting up timing measurements for fire and beam effects. For the burst evidence shot, I'm figuring out the right moment to catch a lifted snake just before it bursts, positioning the inspection camera at 5m distance, 28° pitch, 50° fov, with the yaw angled to get a clear side view of the burst point.

I'm planning to capture frames at intervals leading up to the burst plus aftermath shots showing debris and blood at +1s and +3s. To make the shot clearer, I want the burst to happen within the lit pool area near the egg, so I'm setting up a condition to wait until a lifted snake's midpoint is close enough to the egg's position before triggering the capture.

Values are equalized within ±1-2 across all combos, and leakage is confirmed ambient rather than from nearby kills. Next I need to run the 20-case guarantee sweep, capture gore evidence, and measure timing, so I'll start the sweep now, letting the slot mechanism queue other captures automatically since only one can run at a time.

Usage is balanced across all five powers, with pair counts close and zero snakes reaching the egg. Next I'll run the full 20-case guarantee sweep, followed by the gore captures.

I'm waiting for the sweep to finish, then need to capture the burst, second camera angle, and check whether the group lift capture still reflects the current gore visuals given the timing of the edit4 changes versus the later chaining updates in edit5.

I should also re-capture r20d after the sweep to be safe, and add a quick timing measurement to the capture queue -- measuring aim start to cast ticks separately for fire-only (0.05 beat) and beam-only (0.15) to confirm they're accurate.

I'm noticing the eval indices only capture certain steps, so "fire 0" was actually printing the second powers eval, not the first — I should print all of them to be sure. Also r20e and r20f threw an exception around shoot.mjs:171, which is likely a timeout issue from a long-running GAME.until call hitting a CDP limit, so I want to check those outputs.

I'm checking the timing offsets between the aim start, fire, and beam events, noting the fire happens around 28 ticks after the arm arrives and the beam has a slight delay too. I also notice a search for a condition on fx.t never resolved within the 12000-tick limit, meaning that lookup returned undefined instead of finding a match.

The window I'm checking for the lift (fx.t between 1.3 and 1.36) is narrow but should be caught each tick, so I suspect the real issue is the "near egg" distance threshold being too tight—since the mid-point trails the snake's head by about 1.2 meters, it may exceed 2.6 meters during most lifts. I should loosen that threshold to 3.5 and make sure both the search and the eventual check use the same condition.

I'm noticing the snake burst happened on the left side near the rocks with pieces scattering in the dark, while near the egg there's an odd detail — a piece with a red cap standing upright vertically on the ground, which seems strange and worth double-checking.

That upright piece is actually a physics bug: the resting condition just checks velocity, not orientation, so pieces can freeze standing on end instead of toppling over naturally. I should fix this by adding logic that settles resting pieces toward a horizontal orientation, gradually rotating their axis until it's roughly flat against the ground.

As for the blood spray itself, at this distance it reads as a cloud of uniform bright red dots, almost like confetti, which doesn't match how blood spray typically looks in games — usually darker, clumped, and less uniform.

The droplet color is too bright and unlit for dark areas, so it stands out against shadows unrealistically. Since properly modulating drops by scene lighting is complex, I'll just darken the base drop color so it reads as dark red or near-black in shadow, which is closer to how blood actually looks. I also want to beef up the initial burst with a denser, larger mist cloud with drag to sell the "wet explosion" feel rather than confetti, while trimming the droplet count somewhat to balance it out. Then I'll move on to checking the second camera view.

I'm noticing this different camera 2 burst has pieces with red ends near the right edge, and also spotting red blobs on the lich itself around its hips—those might actually be pieces sitting behind or on the figure rather than separate floor debris.

The wound caps lying around the egg look too bright and saturated for realistic gore in sunlight, reading as cheap red dots rather than dark wet flesh, so I want to darken the color values and fix the upright piece problem by having them settle flat. I'll darken drops to 0.04, adjust flesh colors down (rim 0.08, flesh 0.17, inner 0.12), add more mist at the burst site, then move on to final captures and the lift sequence.

I'm checking that UP's declaration order works fine since it's only used after create_gore completes, avoiding any temporal dead zone issue, and confirming the shared Q, V, and V2 variables are used correctly in the topple branch.

The 20000-tick wait likely timed out without the condition being met, so instead of waiting for a natural lift burst I should force it directly by triggering the lift gesture on a snake near the egg once one gets close.

The condition never triggers across the full 200-second simulation, which suggests lifts don't happen when the midpoint is within 3 meters of the egg. Since targets engage at the head within 3.4 meters and the midpoint trails roughly 1-1.5 meters behind, the midpoint is actually more like 4+ meters from the egg when bursts occur, since snakes approach mostly radially—putting bursts around 3.5-4.5 meters out.

Given this, capturing a lit burst reliably means either using the inspection camera and accepting wherever it happens, or positioning the camera where the light naturally falls—since bursts tend to occur near the pool's edge in dim lighting, that's just the reality of the scene. I'm thinking I need both a wide game view and a closer inspection shot as evidence, and should use the 4.2 limit capture since the earlier 3.6 attempt landed in a dark area. As an alternative approach, I could try forcing a snake near the egg using GAME.force after disabling all powers until a snake's midpoint gets within 2.5 meters, then flip lift on and trigger it.

Let me just use camera 2's view for evidence, relying on the earlier capture as reasonable, and settle on a distance threshold under 4.0 meters, taking the first of the three 4000-tick evaluations near the pool.

I'll capture the lift as it naturally occurs at the pool's dim edge, since that's where the snake's body actually bursts (around 4 m out, triggered at 3.4 m from the egg), rather than staging it in the sunlit center.

I'm reconsidering the snake's position at burst_00 - it looks like it's lying on the ground rather than lifted, so the lifted snake mentioned earlier might be out of the frame given the camera center. Then at burst_03, the red burst effect seems to appear on that same ground-level snake, which could actually be the lifted one viewed from the elevated camera angle.

For the burst effect itself, the dark-red mist with flying pieces landing near the egg pool reads well now, with visible splats and smudges in later frames — it feels ready to show him. I want to set up a few more close-range shots for detail: a nearer view at 2.6m showing pieces and wounds, plus alternating between multiple camera angles (mid inspection, close-up, game cameras) at each instant to capture the same moment from different views, totaling around 32 shots across 8 instants.

I've reviewed the burst showing debris landing in the blood pool. Now I'll capture the same moment from all four cameras simultaneously for the round's sheet.

I'm mapping out the near-view sequence: the snake swelling and lifting, then bursting apart with pieces flying outward, red spray and mist, and finally the aftermath settling with scattered fragments on the ground. The small blood and meat bits should read like bright red confetti catching the light.

Now I'm planning the burst sheet layout: rows for each camera/view (near, mid, second camera, room crop) and columns for a series of timestamps relative to the burst moment, at a compact scale so the whole grid isn't too wide. For the room view, since the burst location shifts on screen, I want to crop each frame around the projected burst position rather than showing the full room at a tiny scale.

I'm checking whether the burst is visible from each camera angle — it seems to fall behind the lich and egg from the room view, and behind the lich from cam2's framing, given its position relative to the pool.

For the sheets, I'll skip the room and cam2 rows for this burst since they add little, and instead focus on near/mid rows, plus a separate 'lift.png' showing the group lift from cam2 following the arm. I'll also generate a simple before/after usage table as a PNG. First let me check the current group lift build before assembling the sheets.

I'm tracking the two rising snakes on the right with the arm following their motion up through frame 10 before the burst at 11, while noting the red wound pieces scattered near the pool and the lich's feet from earlier bursts. Now I'm moving to build the sprite sheets with PIL following the same approach as before.

I'm working out the timing: shot 0 fires around fx.t ≈ 1.3, and the burst occurs about 0.1s later, which lands on frame k=2 (T=6 ticks) — so that's the burst moment I need to align the label to.

Near_03 confirms the split at T=9 (+0.05), matching expectations. Now I want to visually check the burst sheet, bundle everything together, verify the page, and get it ready to deliver.

I'm cross-checking the usage table figures against the raw data, verifying beam, lens, fire, and lift counts line up correctly across the near/far pairings.

The remaining "after" and "all six" counts also match up with the tweaks made post-edit5, confirming the gore visual changes in edit6 didn't affect the director logic — the 20-case guarantee sweep still holds.

Now I just need to bundle everything, verify the burst sheet frames, and update the record with verified pages before delivering.

Good, the gore is accepted. Now I'm thinking the lich's arm should have a sharp pulling motion when the snake bursts — elbow flexing forearm toward the shoulder, hand closing into a fist, maybe a slight shoulder pullback — like he's crushing or yanking the snake, with the pull triggering the burst itself.

Writing the curl motion code...

I also realize the finger-alignment logic that normally points the index at the target will fight the fist curl, so I need to dampen that alignment weight proportionally as the curl activates. And I want the snake debris and blood to drift slightly toward the lich, which already seems to be happening naturally.

For the bias, I'll add a horizontal velocity component (roughly 1.5-2.5 m/s) pushing the burst pieces, meat, and blood jets toward the lich's position, computed from the pelvis location offset upward, normalized into a horizontal direction vector — just a partial pull, not a full redirect. Then I'm timing the curl trigger relative to the lift's rise/hold/swell phases.

Since the lift already tracks when its earliest snake will burst, I'll have it expose a curl-due check, and hook that into the powers hold-phase logic so it calls the lich's curl with the correct arm — the cast function already threads the arm parameter through, so the lift has what it needs to trigger this.

For staggered groups, I'm thinking the simplest fix is to sync all bursts to a single shared timer so one curl covers the whole group, with any snakes added later via extend getting their own follow-up burst.

Defining group burst logic...

I'm designing the curl envelope timing — a quick 0.1s rise, 0.25s hold, 0.45s release — and mapping it to elbow flexion and slight upper arm pull-back, while deciding to leave the wrist neutral since the closing fist already reads as a curl.

Fingers fully curl during the fist close, with the index lagging slightly behind the others and the thumb closing tighter. I'm also stiffening the elbow spring during the curl for a snappier motion, and reasoning through the pull direction — the arm reaches up and forward toward the lifted snakes a few meters away.

For the gore effect, I want debris to lean toward the lich rather than scatter purely randomly: giving pieces and meat chunks a moderate velocity bias toward him (roughly 1.2-2 m/s on top of their outward speed), and aiming two of the five blood jets in his direction so it reads as deliberate without looking scripted.

I realize the index finger direction gets unreliable when curled, so I should weight the alignment influence by (1 - fist) to suppress it during a fist curl. I'm now adding a curl timer to the rig state that resets when a finger starts curling, so I can track time since curl began.

Continuing on: I'm shaping the curl envelope with smoothstep functions for a rise-then-fall weight, feeding it into spring forces for elbow and pitch, storing the fist amount per rig config, then blending finger curl and thumb rotation toward the closed pose using that fist weight, and damping the alignment vector by (1 - fist). I'm also adding a small torque impulse on the chest yaw and pitch toward the casting side when the curl starts, to sell a subtle pull-back reaction.

I'm confirming the sign convention matches the recoil kick pattern, then checking that clamp is defined before it's used inside create_lich, and noticing smoothstep01 gets referenced in the pose function before its own definition appears — I need to verify that ordering won't break things.

Next I'm moving to lift.js to sync the group burst timing, wire up the curl trigger, and add gore bias, which means rewriting lift_fx to reference the shared group time.

I'm verifying a few fixes hold up: the curl trigger correctly avoids re-firing mid-curl, the fx 'done' condition now checks hide state plus timing offset, and the lift update call properly defaults to the expected frame delta since it matches the fixed 1/60 timestep.

I still need to pass dt explicitly into lift.update() rather than relying on the default, thread the arm parameter through the beam extend call, and confirm the powers context object carries all the needed references (lich, get_L, etc.) into create_lift. For gore.burst, I'm working out how to bias particle velocities toward the target direction — pieces and meat getting a directional nudge, some blood jets aimed at the target with spread, mist drifting slightly, and guts still following their free loop velocity.

I'm checking that the meat-spawn replacement text is unique enough to safely target within the loop, confirming it matches the exact object properties being assigned.

I'm planning a test capturing the lich's arm from a side angle right before a curl burst, plus a view of incoming pieces, using a perpendicular camera framing similar to the recoil sheet setup, sampling frames every 2 ticks over about 0.9 seconds.

I'll also add a wide shot including the lich and the burst together, and track the elbow rotation angle over time to verify the curl motion.

I'm tracing the curl gesture timing: the forearm snaps up around frame 7-10 as a pull motion, then lowers by frame 11-15, holding briefly for about 0.45s before checking how it chains into the next gesture.

Since the description calls it "a little pull," I should scale down the elbow bend from 1.18 rad to around 0.8 rad for a subtler curl, and let the lowering overlap the release so the motion flows naturally. Next I want to check the wide view for pieces approaching him.

Looking at the wide shot, the lich is on the left and the burst occurs about 5 meters away at upper right, so debris moving toward him at 0.9-2.2 m/s would barely register within half a second. I'm noting a crawling snake in the lower left of frame, distinct from the flying fragments, and confirming the fragments only drift about a meter in his direction—consistent with "slightly toward him" given the large distance involved.

Rather than manually verifying this with pixel measurements, I could just expose a `gore.pieces_on()` function that returns piece positions directly, which would be cheap to add and let me confirm the toward-lich bias programmatically instead of eyeballing frames.

I realize the pieces list order can shift between frames since filtering active pieces changes as some sink or turn off, causing index mismatches. I need to track pieces by a stable identity instead, so I'll have the pieces function return objects with an id and position, then match entries by id across frames.

The pull effect works and I've scaled it down as requested. Now fixing a bug in my measurement script that mixed up pieces between bursts, so I can confirm the pieces drift toward him.

The centroid of pieces shifts 0.3-2.9 m toward him in 0.83 s, with most individual pieces moving 2.7-4.7 m closer while a few on the far side move away, confirming a genuine directional bias. I'm also checking the third measurement where filtering pieces under t<0.1 turned up nothing, trying to pin down when that burst actually occurred.

Now I'm moving on to bundle round 21, capturing the side curl sheet at 0.8 with the updated elbow value plus the wide view before finalizing delivery.

Across three bursts, the debris center shifts 0.3–2.9 m toward him within 0.8 s, with most pieces moving 2.7–4.7 m his way and only a few going the opposite direction—a clear lean rather than a uniform blast. I'll now re-capture the smaller pull value for the sheet.

I'm working out the timing for each shot using tick-based indices converted to seconds, estimating the burst offset around 0.3s, and pinpointing when the elbow starts moving around the 14th tick (roughly 0.233s in).

I'm tracking the timing of the curl motion — the forearm rises into a fist, holds briefly, then the whole arm drops quickly right after the burst as the lich pivots toward a new target, so the pull reads as brief even though the curl hold itself lasts about 0.35s.

Actually maybe the timing lines up with a new gesture triggering right after the burst — the urgency check re-fires a chase/lower gesture that swings the arm down toward the floor before the hold timer would normally allow it, which would explain the early downward drop I'm seeing at +0.07s.

This makes sense as a director-level interaction: in lift-only high-power tests, the hand is nearly always busy since snakes keep arriving, so the next gesture cuts the curl short more often than in the mixed-power tests. To make the pull read cleanly, I should hold the channel busy through the full curl duration (~0.3s post-burst) unless something is genuinely urgent, meaning I need to mark the lift as busy during that window.

The pull reads correctly, but the arm drops too soon since the next gesture pulls the hand away right after the burst. I'll extend the lift's hold to 0.3s post-burst so the curl completes first.

Still the same drop at +0.07, so it's not the chain issue. I want to verify lift's busy check is actually a function call, then add logging of phase, ab, pw, point y, fist, and elbow per tick to trace what's happening around that point.

The log eval failed on m.y even though point.y checks out and recoil is properly exposed - I need to find the actual FATAL error line since the message got cut off before I could see what's really undefined.

I realize there's a naming collision: I defined `recoil: RC` in the lich object, but later added a getter also named `recoil` that overrides it with a different value. I need to rename the test export to `rc: RC` to avoid the clash.

The phase remains 'hold' but the shoulder rotation drops sharply from -1.66 to +0.3 within 12 ticks after the burst, roughly a 1.9 rad swing. I'm trying to figure out why, since the aim target stays essentially the same — the small shift in aim y doesn't seem to explain such a large change in shoulder pitch.

The recoil curl term is too small to account for it, and tracing through the pointing weight logic (pt) shows it's set to 0 with fist=1, triggering an early return that shouldn't affect this. The rc.p spring target is also small, so I'm now looking at whether the Q.p spring itself is moving toward a different target — possibly tied to how AIM shares the same Vector3 object across frames, meaning the aim point value at tick 19 might be stale or mutated unexpectedly.

The 0.2m difference in aim y isn't large enough to explain a 2 radian shoulder swing, so that's probably not the cause. The curl impulses touch chest yaw/pitch, not the shoulder directly, so I need to trace how rc.sh's clamp combines Q.p.x, rc.p.x, and tr to actually produce that rotation value.

Tracing further, rc.p's target depends on a mix between the trail position and the aim target weighted by pt, and when pt equals 1 it fully switches to the aim target computed from the angle to the target relative to the shoulder frame — if the target sits well above the character, that angle could swing sharply negative, which might account for the large rotation change I'm seeing.

Confirmed it's the same arm, so I should isolate the spring value from the raw position by logging the spring's x separately from rc.p.x to see where they diverge.

I notice the aim point jumps dramatically at tick 19, from near (-0.97, 1.82) to (-2.47, 1.62, -2.77), landing close to the lich's position. I'm digging into the aim_point logic to figure out why it returns this stale averaged value when the held array is empty instead of recomputing fresh.

I'm tracing through the update order: powers.tick runs first, then lift.update prunes hidden snakes from the held list, but the burst that hides the snake happens later in snakes.update — so the hidden snake lingers in held for one extra tick before pruning kicks in. That still doesn't explain where (-2.47, -2.77) actually comes from, since AIM should just be the last held average. I'm now wondering if a respawned snake is sneaking back into held before its fx state gets properly reset.

Ah, that's it — the extend logic lifted another urgent snake mid-channel, which shifted the aim average toward that new target. That's the director's backstop behavior for heavy traffic (lift-only fallback), legitimate but it breaks the pull curl's visual continuity, so maybe extend should hold off while a curl is active.

I could defer extend while a group is within its pull window, checking g.t against the curl-lead and after-window bounds, and only letting extend fire once that window closes — since the urgent snake would still reach the egg in time even with a short delay.

Found the issue: an emergency lift was triggering mid-pull when a snake got close to the egg. I'll make that emergency lift wait out the 0.3s pull, since a snake 2.6m away takes about 1.2s to reach the egg, leaving enough margin.

I'm puzzling over why the aim point at tick 19 lands near the lich's own position rather than extending further out, and trying to figure out what else could be setting that aim value since the lich doesn't seem to have moved much.

Tracing through the aim logic: when a channel is active, the aim point gets copied from `aim_point()`, which pulls from a held snake's spine midpoint. But when a snake bursts, it's hidden and pruned from the held list before respawning — so I need to check whether the spine data persists through that respawn cycle, since spawn resets position but doesn't rebuild the spine unless the snake isn't delayed. That means at tick 19, right after a burst, the held list should be empty, so the aim point should just be whatever was last computed — unless a second snake in the same group is still contributing a different value.

I'm going to add a debug getter that exposes each held snake's actual midpoint position and hide state at ticks 17-21, since right now I only have access to the held count, not the underlying positions.

I'm seeing two separate groups being tracked — one near the target and another extended group lifted later near the lich. Since the aim averages both positions, it ends up pointing at the empty midpoint between them, and once the first group bursts, the aim snaps over to the second group.

The fix is to have the arm aim only at the currently active group — the one whose pull hasn't finished yet — rather than averaging across all held snakes. I'm structuring each group to track its own aim point and snake list, computing the aim as the average position of that group's still-held snakes, and holding onto the last known aim once a group bursts until the system moves to the next group in burst order.

Found the issue: his hand was averaging two lifts ~6 m apart (one from the emergency path), causing it to aim between them and jump. Now I'll have it track one group at a time, following whichever bursts next until it finishes its pull before switching.

I'm keeping the aim on group 1 during its pull, switching to group 2 after the timing gap. There's a minor inconsistency where the second group gets lifted while the hand still points at group 1, but I'm treating that as an acceptable backstop since the curl motion still aligns with pointing at group 2 later.

Now I need to recapture the pull sheet, then verify the guarantee since the extend deferral affects the backstop — I'll run the pull capture first and let the 20-case sweep run in the background afterward.

The arm sweeps up into a clear fist curl that holds through +0.3s, though this run uses a slightly different camera angle since the director changed. Now I'll run the guarantee sweep of 20 cases alongside the usage run covering extend deferral and aim changes, executing both in the background sequentially.

I'm worried the combined command might exceed the 600s timeout since the test cases plus usage checks could take around 17 minutes total, and I'm unsure if backgrounding avoids the timeout enforcement. I'll monitor progress around the 10-minute mark and rerun the usage check separately if it gets killed, then move on to writing the round 21 record entry.

That lift count of 1 for beam+fire alone is probably a boundary artifact — a gesture that started during the previous lift+lens case may have completed just after the power switched, getting attributed to the new case instead. This seems like a minor harness quirk rather than a real behavioral issue.

Though thinking about it more, removing a power mid-aim shouldn't let the cast still fire. A quick fix in tick: if the phase is 'aim' and the active power is no longer enabled, cancel it by dropping the phase. That's a sensible guard worth adding now.

With that in place everything balances out, so I'll bundle, verify, and deliver.

I noticed usage stayed balanced across the cast, but found one edge case where a lift was counted despite the harness switching lift off mid-gesture. I'll fix this by ensuring an in-flight gesture gets cancelled when its power is removed.

The cancel change only affects the director when a power is toggled off mid-aim, and since the 20-case sweep sets powers at the start of each case, it barely touches the timing being tested — it can't be what's causing snakes to reach. My earlier verification predates this one-line tweak, so I should consider running a quick short check to confirm, even though the full sweep takes about 10 minutes.

The owner wants pointing constrained to a front 180° half-plane, so if a target falls behind, the character should either turn his body to face it or drop the target—though he's uncertain which policy is right. Right now facing is tied to movement direction, since he turns toward wherever he's sent.

For the arm itself, aiming uses pitch and roll clamps that let it swing backward slightly (up to about 51°) when the target is behind, which looks a bit unnatural. That raises the idea that maybe both arms could split targets—one pointing left, one pointing right—achieving that "cross" style 180° opening the owner described, rather than only a single arm pointing at a time as it works now.

The real fix seems to be decoupling facing from movement during combat: while pointing or channeling, the body should twist just enough to keep the target within roughly ±75-90° of its front, even if the player moves it in a different direction. Since the lich floats, treating this like twin-stick controls—moving where sent but strafing/facing the target independently—feels natural.

I'm working out the actual threshold logic: track the angle between his facing and the target direction, and once it exceeds around 70°, rotate his yaw just enough to bring it back into range rather than letting the target slip out of view.

When he's moving, I want his facing to prioritize the movement direction but clamp toward keeping the target within that 70° front cone, so he faces as close to his travel direction as the constraint allows — even moving backward relative to his facing if needed. When idle, his facing simply holds until something (like a gesture) demands he reorient toward a target that's behind him.

Then I'm considering arm selection — he should pick whichever arm sits on the same side as the target — and head/chest rotation limits of roughly 63 degrees for gaze tracking. The "arms in a 180-degree cross" idea seems to apply mainly when juggling multiple simultaneous targets, but for a single target with one arm pointing, this simplifies down to just picking the correct-side arm without needing the cross constraint.

Since facing is unconstrained, it can always track the target, but fast player movement could transiently push a hand target past its arm's limit, so I'm considering: if a target exceeds the limit for more than 0.3s during a hold or channel, the target gets dropped, though I need to think through whether that would cancel an active beam channel's effects.

I'm leaning toward a hard fallback where exceeding 110° lowers the arm even while the facing turn speeds up to compensate. I could offer both behaviors as a toggle — default turns to keep the target in front, alternative lets go and drops the target/cancels the attack when it swings behind, matching what he suggested.

I'll define two target-selection and facing modes: preferring in-front threats within 90° when choosing a new gesture target (urgent ones override), then Mode A turns the body to keep targets within 75° even as the player moves him independently, while Mode B keeps facing tied to movement and drops targets that fall behind instead.

For implementation, I'm thinking mover.js needs an external facing constraint alongside the movement-driven yaw: powers can set a face target with an angle and half-width tolerance each tick, and the turning logic clamps the desired yaw to stay within that tolerance range of the facing direction. When not actively pushing, the last yaw persists but still gets adjusted by the face constraint, so the character naturally turns toward the target when needed.

I'm also increasing the turn spring frequency from 0.8 Hz to 1.3 Hz whenever facing is active, so the turn happens fast enough to keep up, while the head-lead lean still derives from the difference between desired and current yaw during pushing. Then in powers.js, I'm wiring TURN mode to set mover.face during aim/hold phases and clear it otherwise, and sketching DROP mode logic where a large angular mismatch between facing and current yaw during aim/hold triggers a drop.

I'm working through some edge cases: when a hold ends the channel power should keep running independently, but a beam still tracking the finger position after the arm lowers looks wrong, so dropping should stop the beam explicitly, and similarly the lift's curl animation should only continue if the hand is still gripping rather than firing on a schedule regardless of arm position. Given this is getting complex for a feature that may not even be wanted, I'm leaning toward implementing TURN mode fully now and treating DROP as an optional toggle.

For DROP, I'm reasoning that new targets behind the unit shouldn't be selected unless urgent, and if a target rotates past 90° behind it should be released—canceling aim, releasing non-channel holds, cutting beam channels short, and letting go of lift channels without a curl animation (though the snakes still burst independently). I'm also thinking both TURN and DROP should prefer front-facing targets to minimize turning, and considering a per-arm constraint limiting each arm's aim to its side's quadrant plus a small overlap across center.

I'm verifying that with pick_arm choosing the arm matching the target's side and the target within ±75° of facing, the arm angle stays within front-to-side bounds, and checking the gaze/head turning clamp stays within its limit. I'm also confirming the relative-angle calculation matches the mover's yaw convention used elsewhere, then planning a headless test: spawn the lich, have it cast, move it so the target rotates behind, and compare the pointed-target angle over time between TURN and DROP modes, including a case where the target starts behind the lich from the outset.

For target preference in the gesture logic, I'm reordering non-urgent targets so front-facing ones are picked before those behind, sorting by a behind-flag then distance to the egg, and I'm also planning a HUD line tied to the O key toggle.

Now I'm implementing the drop mode behavior in powers.js: making beams stop and thin out, adding a lift.release() that lets the hand let go of held snakes without triggering the curl animation, and adjusting the busy/aim state so the cast resets properly afterward.

I also realize the placeholder targets claimed by a stopped beam would stay frozen forever unless I free them — so in stop(), I'm clearing s.fx for any targets past the current pierce index (and the current one if it hasn't been pierced yet) so they're released back to normal.

Facing only updates through want_yaw, so when pushing the movement overwrites it each tick and the face constraint still applies on top; when not pushing, want_yaw persists with the constrained value, so he naturally keeps facing that way even after pointing ends. For head lead, motion.look also draws from this same constrained want_yaw when pushing.

I'm defining a mover face state with a target yaw and half-angle tolerance, then adjusting want_yaw during pushing to stay within that facing cone, using a faster turn rate when the face constraint is active. I'm also adding a FACE mode config for powers.js with two behaviors -- turning to keep a target in front versus letting go of it -- along with helper functions to compute relative angle and whether a target is behind the character, sorting threats so behind-targets are deprioritized, and reasoning through how "drop" mode should avoid immediately re-triggering gestures on targets that are behind by having urgent behind-targets trigger a turn instead.

Each tick I'm toggling the face constraint on or off depending on the gesture phase and mode, and in drop mode I'm handling the aim/hold phases so gestures on behind-targets get released or canceled unless forced, with a forced flag set at gesture start for urgent behind-target cases that require turning even in drop mode. I'm also working out hold-phase chaining logic where turn mode causes the body to rotate toward newly picked targets.

With that settled, I should add the HUD, an 'O' key toggle, and expose GAME.facing(i) — time to start writing the implementation.

My earlier let_go logic was messy, so I'm redoing it with a free_hand flag: releasing sets free_hand=true so busy() reports false and existing snake groups still burst at their scheduled time but skip the curl effect, while starting a new cast resets free_hand back to false without touching aim_point.

I also confirm extend won't fire after let_go since the phase drops too low, and that the curl-skip check and powers.js's N constant are already correctly wired — I just need to apply these fixes to the actual script before testing.

Tracing through the gesture logic: in DROP mode with urgent targets behind, the pick correctly selects the first one and triggers a turn; in TURN mode the must_turn flag doesn't matter since facing is always on. I'm confirming that chaining through start_gesture properly resets must_turn for each new target, and now checking how the drop counter increments within the aim branch condition.

I want a test plan with two scenarios: one stationary but facing away from the egg to measure how far off-target the pointing gets over time, and one with the lich moving randomly around the room to measure the same off-target percentage plus drop and reach counts for both TURN and DROP modes. To compare against the old behavior I'm considering adding a hidden override flag that disables facing entirely so I can run a before/after baseline, then driving the simulation with periodic random goto commands.

I realize calling GAME.step repeatedly renders every frame, which is too slow in software GL, so I should switch to GAME.until, which ticks without drawing and lets me sample state through its condition function instead.

This background process could take 15+ minutes, so I should just kill it and rerun rather than waiting, since it's holding the render slot. I'll look for a way to stop the task.

I should verify the Chrome processes spawned by shoot.mjs actually got killed, since the headless instances use temp user-data-dirs. I'll check for lingering headless chrome processes and clean them up using tasklist/wmic if any remain.

I notice a few stale node shoot.mjs processes and a headless chrome still lingering, likely leftover children from the stopped task. I should verify their command lines to confirm they're from my r22a run before killing them.

These processes aren't mine — they belong to another session's harness run, likely a different project like "r1-enemies" or "r1-director" running concurrently. I should leave them alone since my own run's processes are already gone, and remember that SHOOT_SLOTS=1 is scoped per project, not globally.

I'll keep my runs lean by avoiding rendering inside loops — I'll rewrite the walk to use GAME.until with a sampling condition that collects points without rendering each tick, capping at 89 ticks with a single render at the end, while GAME.step still renders once per move which is fine.

Those extra processes belong to a different session, so I'll leave them alone—my stopped run left nothing behind. I'll re-run the measurement now without rendering every tick, since that's what was slowing it down.

Looking at the random-drive results, the target is behind the player 36.9% of the time with the old setup and over 120° behind 20.7% of the time. With turns enabled that improves to 13.2% and 6.1% respectively, but it's still not great — likely because the turn spring can't react fast enough, or the facing constraint isn't actually being enforced properly when the player moves.

So I'm planning fixes: delay the arm's pointing weight ramp until the target is within ±95° so the body can turn first, tighten the "arrived" threshold to ±80°, and speed up the turning spring significantly (1.3→2.0 Hz, amax 22→40, vmax 5.5→7) so the body catches up faster while pointing. For urgent/quick casts I'll relax that to ~100° tolerance. Then I'll re-measure the percentiles after implementing these changes.

I found the target was still behind him 13-15% of the time due to slow turning and premature arm-raising. I'll speed up his turn while pointing and delay his arm until the target is within 80° in front of him.

I'm noticing my sed edit for the yaw clamp didn't fully apply—line 65 seems unchanged, and the "amax already declared" error suggests there's a naming collision with another amax variable used for movement acceleration elsewhere in the tick function.

I should refine the metric to only count aim time when the arm is actually raised and pointing, rather than including the time the head turns while the arm is still down. I'm also noting that targets between 75° and 90° make up about 36% of cases, which is worth separating out from the harder >90° cases.

With the arm raised, the old drop rate of 36% falls way behind: turns now only cause 2.4% drops above 90° and 1.1% above 120°, while lets-go cause 1.5% and 0.1% respectively, with just 10 drops across 60 seconds of random driving. I'm trying to trace the remaining 2.4% turn failures to transient moments of fast movement, and wondering if the 180° max is coming from the lift aim combined with the extend group.

I could clamp the arm itself so that if the relative angle exceeds 100°, the arm weight temporarily fades down while the body turns, avoiding that awkward "pointing behind" look, then rise back once the body catches up — adjusting the hold-phase weight logic to fade toward zero over 0.2 seconds instead of snapping straight to 1. The beam would still leave from the finger even as the arm lowers, which might look slightly off but should be rare enough to accept. I'll implement that hold-phase fix, re-measure, then move on to the guarantee sweep and capture evidence — a sequence showing the lich turning to face a snake and pointing, and another showing it reorienting mid-channel when moved away — using goto commands to reposition him for the test.

With his arm raised, the target ends up behind him only 2.4% of the time on turns and 1.5% on drops, down from 36% before—and in the rare cases where he's spun faster than he can turn, his arm now dips instead of pointing backward.

The turn thresholds look good enough now. Next I want to run the guarantee sweep with the director's updated target preference—20 stationary cases across both modes, using default turn settings, plus checking the moving case still reaches zero over the 60-second window before capturing evidence.

For the evidence captures, I'm planning two scenarios: one with the lich facing away from the egg as a snake approaches from behind, turning and firing, comparing old vs new behavior side by side with camera 2 at close range; and another where he's holding a lift/beam and moves away, contrasting TURNS (facing back toward the snakes while moving) versus LETS GO (facing the movement direction and dropping the arm so the lift bursts on its own). I'll do the captures first since they're quick, then run the longer sweep in the background.

Now down to just 1.5% arm-up time occurring with the target behind him and 0.5% past 120°. I'll capture the evidence next: he turns before pointing at a snake behind him and gets moved away while holding a lift in each mode.

I'm tracking the angle values for each animation state—old pointing angle staying at 178° before firing at 176°, the new arm sequence rotating from 79° to 74° before release, and the "turns away" case holding at 74° or less while moving. I'm also working out the "lets go" logic, where crossing past 90° triggers a drop before a new aim point kicks in.

That's enough detail—now I want to pull up the actual frame data for these states to build the reference sheet.

I'm noticing the two scenarios target different sides — in the old frames the beam fires right near the egg, while in the new one it fires left toward new_11, suggesting different snakes were selected due to facing direction differences.

I'll build a larger comparison sheet, cropping around the lich figure with bigger tiles and six frames per row to make the facing/aim more legible.

Comparing the two versions, in the old one he faces the camera and fires behind-right with his arm reaching back, while in the new one he actually rotates his body and legs before firing to the right, having turned roughly 100 degrees. The target seems consistent between the two, likely still aiming toward the same snake positioned to the right.

I'm tracking the lich's movement toward the camera while he keeps facing back toward the snake, arm raised — then around frame 06 he turns and his arm shifts to a new target off to the left. For the sheet, I'll need a tighter crop that follows the lich as he approaches the camera.

I'll use a larger crop region covering the lower-left two-thirds of the frame. Next up: sweep the background, then finish the sheets, bundle everything, and deliver, along with recording progress to memory.

I'm re-checking my frame-by-frame eval values against what I actually measured — it looks like frames 0 and 1 were both 0, not 3 as I had written, with frame 2 jumping to 178.

Comparing old vs new: old fires the hold at frame 8 with values [0,0,178,178,178,177,177,177,176,...], while new fires at frame 11 with values [0,0,0,0,0,79,75,74,...] — confirming the eval is captured right after the shot on the same tick. I'm also cross-checking the moved-away sequences (f_turns and f_letsgo) frame by frame, noting that the 169 value at frame 4 in f_letsgo corresponds to an 'aim' reading right after a drop, while the arm is still raised.

I'm investigating why the beam sometimes appears to start from the egg rather than the lens—checking whether the ribbon's neighbor attributes default correctly, and suspecting the miter calculation in the vertex shader might be affecting all ribbons uniformly instead of just the intended ones.

My working theory is that the lens sits above the egg inside the sun shaft, so from the camera's perspective its projected position could visually align near the egg, making the beam look like it originates there even though it's actually starting from the lens.

I'm reconsidering whether recent ribbon shader changes (the miter/pieces update) might have broken style 2 rendering, but the pv/nx fallback logic checks out fine for lens ribbons. I'm shifting to suspect the actual lens position value itself might be computed incorrectly.

Actually the quick-lens shortcut (skipping FORM/CONVERGE phases) seems fine too since it just makes the glass scale instantly. I think I need to actually capture frames of the lens alone from both cameras to check whether its position genuinely projects onto the egg area from the room camera's viewpoint.

I'm now tracing what's changed with the lens since it last worked correctly — the fairness rotation affecting how it casts, the quick-lens rescue path skipping the charge phase, LENS_ENGAGE timing, and the ribbon changes.

I'm checking whether the beam's ribbon spawn logic could be picking a stale or already-held ribbon, which would explain the beam appearing to start from the egg instead of the lens position, and whether the miter code applied to the lens beam is interfering.

I should stop speculating and actually check real behavior—setting up a test with the room camera and a second camera cycling through a lens with lens-only power to observe what actually happens rather than reasoning through the code paths abstractly. There's also the question of lift-pull direction: when pulling with lift toward the player, the burst direction seems to use the player's position at burst time rather than a fixed target.

I'm trying to parse what "current pull" versus "lift start" position actually means here — maybe it's about the arm/forearm curl direction tracking the lich's live facing rather than a stale direction captured when the lift began, since the arm should stay pointed at the snakes even if the player turned mid-lift.

I think the fix is to make the pull continuous rather than a one-time push: for a short window after the burst, apply a gentle decaying acceleration toward the lich's current position so pieces curve toward him if he moves, instead of flying toward his position at burst time. I want to double check the lift code to see where the toward-direction gets locked in, since that fixed-direction snapshot might be the actual bug rather than needing continuous attraction.

I'll add a short-lived attraction force pulling debris pieces, meat, and drops toward his current position, decaying over about 0.7 seconds so they curve as he moves.

For the leakage effect, I'll swap the glitter dots for a heat-haze style distortion streak with prismatic tint pouring from his head, and give dying snakes a similar warping smoke-dissolve effect rather than plain particles. This will need a screen-space distortion technique that samples the scene color behind the streak and offsets the UVs for refraction.

Since three.js lacks a built-in grab pass, I'm planning to render the distortion ribbons into a separate offset buffer (UV offset in RG, tint in B), then do a full-screen pass sampling the world render texture with those offsets, splitting R/G/B samples slightly to create the prismatic chromatic aberration look.

Now I need to figure out where in render.js to hook this in and how to handle depth testing so the distortion geometry occludes correctly behind walls, since sharing a depth buffer between separate render targets isn't straightforward.

For the streaks themselves, I'm thinking camera-facing ribbons curling outward from the head with a traveling pulse along their length, offsetting the background perpendicular to each streak so the chromatic split creates prism-like edges — like refractive anime wind lines. For the leakage effect, the dissolving snakes should emit similar distortion smoke puffs as they break apart.

Now shifting focus: I want to swap out the wind power for a rock throw — telekinesis lifts a rock and hurls it along a line so it strikes multiple snakes at once, possibly tumbling along the ground to crush them.

On impact, I need crush gore: the snake body flattens, blood bursts outward from the impact point, and the snake dies with a twitch before sinking. For the rock itself, I'll pull from the cave's existing stone assets.

For the crush effect, I want a flattening ring at impact with gore fx: blood spray, meat bits, splat decal, twitch, then sink — I'll add a gore.crush helper that handles the drops/splash while the snake fx handles the flatten/twitch/sink sequence. For the telekinetic lift itself, I like reusing the prismatic distortion warp around the rock as it's held — that ties nicely into the shared visual language the owner wanted across the remaining attacks.

Now I'm laying out the build order: fix the lens bug, add continuous pull-toward-position for the lift, build a distortion pipeline in render.js with chromatic split compositing, rework the leakage effect to use warp-based streaks and dissolve smoke instead of glitter motes, then implement the rock throw (emerge, telekinetic hold with warp trail, throw, crush, multi-hit alignment, and rock after-life).

This is a lot of work, so I'll start with fixing the lens capture bug first.

I'm working out the beam positions relative to their light sources - one large beam in the top row extends off-screen from a high lens position, while another beam appears to run vertically from an elevated lens down toward the egg.

Since the room camera sits high and looks down while the lens forms only a few meters above the egg, the beam's projected start point naturally lands close to the egg on screen — which matches earlier accepted rounds using the same lens height formula, so the geometry itself hasn't changed. I'm now checking whether a "quick lens" variant might behave differently and affect where the glow appears to originate.

I'm double-checking the lens position drift and ribbon miter code for edge cases, but the zero-vector skip condition seems fine, so the bug likely isn't there. Let me instead look at the room camera views of a lens directly.

I'm checking the lens beam origin in the room camera view — it starts from the lens in the shaft rather than the egg, so I'm wondering if the egg-origin behavior only shows up with multiple lenses or a different lens type, since this run only has a single lens.

Tracing the actual position calculation, the lens sits along the shaft axis at some height offset, so unless that height rolls near zero it shouldn't land near the egg's floor position — I'm double-checking the random height range and whether the quick lens spawns differently. I'm also considering whether the bug is really a ribbon or beam-pool indexing collision, where beam segment pieces spawning into the same pool as the lens core ribbon might overwrite or misplace entries.

I'm now tracing whether a lens core reference could get stale after its ribbon slot gets reused by the beam, checking that release and respawn logic properly clears the previous/next pointers so a freed ribbon doesn't retain leftover linkage.

Still not finding the actual leak source, so I'm planning to instrument the lens update to log whenever a core ribbon's position lands close to the egg, since the shaft's axis passes directly over it — that seems like the likely spot where "from the egg" origin is coming from.

I should actually look for real anomalies instead of theorizing — running all six for 90 seconds and logging every lens firing (position and spot) so I can flag any case where the lens height drops below 2.5. I'll need to expose the active lens list for testing purposes.

Both cameras confirm the lens beam starts correctly at the glass in the three casts I checked, so the bug must be intermittent. I'll log every lens firing during a 90-second run at full power to catch one that starts low or at the egg.

I notice a spot appearing at exactly (0, 0.22, 0) twice, which suggests it's actually a default/uninitialized value rather than a real position — that's the ground height at the origin plus a small offset, meaning beside() never actually updated q.spot for this case.

This happens when the targeted snake isn't free anymore (already claimed or killed) — beside() skips writing to `out`, so the spot stays at its initial zero vector, which visually reads as the beam firing at the egg's location. The real bug is that when a lens's target snake becomes unavailable mid-formation, it should retarget or dissolve instead of defaulting to origin; I need to check whether this only happens if the snake was taken before the lens's first update tick during the FORM phase.

Writing retarget and cancel logic...

I'll extract a helper for computing the ring position on new targets, and I need to handle claims — since the lens module doesn't track clock state directly, I need to figure out how to set claim/claim_until when retargeting onto a new snake.

For the lift pull effect, I'll build a debris burst mechanism where each fragment continuously attracts toward the current position rather than a fixed point, tracking a pull duration per item.

I'm computing acceleration as a normalized direction vector toward the target scaled by a strength factor and remaining pull time, applying this across pieces, meat, blood drops, and guts nodes so everything curves toward him as he moves—effectively a telekinetic pull. The initial burst direction bias still gets set from wherever the effect originates at the moment of impact.

Now onto the bigger piece: I need to look at how distortion is rendered, so I'll check render.js.

Found it: when the lens's target snake dies before it fires, it defaults to the room's origin—right where the egg sits—causing accidental egg hits (2 of 7 beams in a 90s run). I'll fix this by having the lens retarget to the nearest free snake or dissolve harmlessly if none remain.

I'm handling the logic where a snake's ownership can be reassigned to the nearest free snake when its original claim gets taken, falling back to dissolving unfired if none are available nearby.

Since snakes track their own egg reference rather than the lens, I'm setting a 7-meter distance cap from the egg and initializing each ring's spot at spawn time so it's never left at the origin by default. When a ring gets cancelled I mark it fired and fast-forward its timer past the fade-out window so the core never actually forms.

I need to check snake availability on every tick before firing, not just once, and also verify claims are released properly through the lens's use_claims helper when a snake is claimed for a limited duration.

I'm checking that variables referenced before their declaration line are safe because they're only accessed inside functions called later, avoiding a temporal dead zone issue. Now I'm revising the update logic's else branch to add an additional condition checking whether the queue item hasn't fired or is a core item.

Now I need continuous attraction pulling debris toward the current position instead of a fixed origin spot. I'll have the gore object track a target position updated each tick, and give each burst's debris a temporary pull duration so it gets drawn toward that moving target before settling.

I'm reconsidering the balance between the initial outward bias (at burst time) and this new continuous pull — I want to shrink the initial bias a bit and add a modest continuous pull force (around 5 m/s² over 0.6s) so items subtly track the player's current position without everything rushing toward him.

All 8 beams, including the emergency lenses, are now hitting snakes instead of the egg. I'll factor in that the burst continues tracking his current position as pieces scatter, not just his position at the moment it triggered.

I'm deciding to give each item its own pull timer instead of a global one, so older bursts don't get re-pulled by newer ones.

I'm checking that `L` is declared before it's referenced in the gore creation logic, and confirming the ordering of mover, fire, snakes, fx, gore, and powers in main.js is correct. I'm also verifying the `follow_on` variable used inside the burst function is properly scoped.

I notice that ribs, verts, and scraps don't get a `pl` property set during spawn, unlike meat pieces, meaning they won't be pulled toward the follow point — I should patch `burst_at`'s returned object to include `pl: PL` so those pieces get pulled too.

I'm designing a test to see if the burst pieces track the lich's current position versus his position at the moment of the burst: I'll trigger the burst, then move him sideways, and measure whether the pieces' centroid displacement projects more strongly onto his updated location or his original one.

He moved 1.39 m sideways in 0.83 s, so pieces drift only 0.04-0.47 m toward him, which seems modest but proportionally reasonable given the pull decays over 0.7 s and he's 6-7 m away, changing the angle by only about 12°. I wonder if he actually meant something different, like the pull should track toward wherever the player is currently pulling from rather than a fixed point.

I'm second-guessing whether the toward-direction is computed at lift start or continuously, but tracing through get_L() confirms it uses the current position at burst time, which matches the continuous-pull interpretation. The arm also keeps aiming at the lifted snakes as he moves, with the curl pulling toward his body — so I'm confident this is working as intended, and I'll move on to look at the distortion system in render.js.

The live pull is working correctly—pieces track and bend toward him as he moves, with the small bend angle matching his distance. Next I'll check the renderer to add a see-through distortion layer with rainbow fringes for the shared warp look.

I'm designing a distortion layer where a warp scene renders offset and chroma-spread data into a floating-point render target, sharing depth with the main world scene for proper occlusion.

I'm working through whether two render targets can safely share the same depth texture in three.js without one pass clearing the other's depth — deciding to disable autoClear and only clear color when rendering the warp pass. As a fallback if sharing the depth attachment causes issues, I'm considering manually sampling the world depth texture in the warp fragment shader and comparing it against the fragment's own depth to fake the depth test.

I'm now planning the compositing math: using additive blending in the warp target so overlapping streaks accumulate, then in the final composite reading the warp buffer's offset and chroma channels to split the world color into RGB channels sampled at slightly different UVs, producing a rainbow-fringed refraction effect with an optional faint tint blended in.

Nearest filtering on the world render target would make warps look blocky at this pixel-art resolution, so I'm opting for manual 4-tap bilinear sampling in the shader wherever warp coverage exists, to keep the refraction feeling smooth rather than snapping to pixel grid.

Now I'm sketching out the warp emitter system: streak ribbons that bend screen offsets perpendicular to a curve with a bell-shaped profile across the width and a rippling sine wave along its length for a heat-haze effect, plus smoke puffs as point sprites for softer distortions.

For the leakage visuals, I'm replacing the old motes-and-rings look with skull-emitted wind streaks that spiral outward and fade after about a second, spawning several per second scaled to the reach, and I'm considering turning the floor ring into an expanding distortion ripple like a shockwave.

For the dissolving snakes, I want to swap the glitter motes for rising warp smoke puffs at the dissolve edge, with a final burst when they're fully gone, while toning down the prismatic glow so the smoke effect reads as the primary visual.

For the new rock-throw power replacing wind: a rock tears free from the ground near the lich, rising into a trembling telekinetic field beside his casting hand with dust and debris cracks, then he thrusts his arm forward to hurl it in an arcing path toward the target(s) for a crushing hit.

For multi-hit logic, I want the throw to follow a line from the rock to the primary target, extended past it, so any snake whose body falls within about 0.35 m of that line also gets struck — like a bowling ball, the rock flies low at snake height, hits the first target, then bounces or rolls along the ground crushing others in its path. When there are multiple snakes nearby, the aim direction should be chosen to maximize how many lie along that line.

Crushed snakes flatten at the impact point with a radial blood burst, splash decal, scattered meat bits, a twitch, then sink into the ground like other corpses — including a crushed-head variant. The rock itself rolls to a stop, sinks after a few seconds or crumbles to dust, and with limited power capacity multiple rocks can be lifted and thrown in sequence. I'm also picturing a warp shell effect around the held rock — rings or ribbons that trail during flight, tying into the existing leakage/warp visual style.

Now I'm swapping wind power index 2 out entirely for ROCK, renaming references and keeping the same key slot 7, and removing wind.js since it's no longer used (git history preserves it if needed). For the rock mesh itself, I want to reuse the convex-hull generation approach from the cave stone code, so I'm checking cave.js for an existing hull-based rock generator to borrow.

I'll add a warp buffer so effects can shift the screen-space image, with RGB channels offset slightly for a rainbow fringe. Now checking how the cave builds its rocks so the thrown rock matches them.

I'm checking which material rocks should use versus the floor, so I need to find where M.rock or similar is defined.

Since the rock is moving, it needs dynamic lighting instead of the baked static GI the material uses, so I'll switch it to a MeshLambertMaterial with the rock texture and gi_dynamic, and expose the cave rock texture in the return object. Now I'm moving on to implementing warp support in render.js.

I'm setting up a separate warp render target with a half-float RGBA buffer and no depth, rendered after the main world pass with a clear each frame. In the final fragment shader, I'm sampling this warp texture to distort the UV lookup into the world texture per color channel, creating a chromatic offset effect, with a fallback to the normal sample when the warp is negligible, plus a faint brightening/haze blend based on the warp's alpha. I'm also writing a manual bilinear sampling helper since the warp texture uses nearest filtering.

Now I'm adding a depth comparison to the warp material itself, comparing its own fragment depth against the world depth texture to determine visibility.

Then I'm moving on to warp.js, where emitters create streak pools built as triangle-strip ribbons that expand in screen space like the other fx ribbons, using per-vertex neighbor directions for the curve shape.

Each streak is a set of CPU-updated points flowing outward along a curved path, with puff pools using point sprites for swirl offsets and rings implemented as closed circular streaks lying flat on the floor. I'm working out how the streak's path curves outward from a head point, rotating its direction around the up axis at some curl rate as it travels.

Using a derivative-of-gaussian shape gives that lens-like bending effect on both sides, with smoothstep envelopes at the ends and traveling ripples along the length, plus prismatic chroma and low coverage alpha for a subtle transparent tube look. I'm setting realistic pixel amplitudes and world-space widths for the streak, then moving on to designing the smoke puff sprite with a rotated noise gradient offset field.

Now I'm working out the swirl and turbulence math for the puff (rotational offset with falloff and noise, amplitude decaying over lifetime), rising and expanding motion, and how point sprite sizes convert from world units to pixels via scale/depth. Then I'm sketching changes to leak.js: replacing head motes with streak emission, defining emission rate scaling with reach, and randomizing each streak's origin, direction, speed, and length.

I'm designing the floor warp ring effect—a closed circular path of points expanding outward from the lich at floor level every couple seconds—and planning dissolve-front puff emission for the snake, including a possible final burst of puffs when the body fully dissolves.

I'm dropping the glitter/prismatic mote idea entirely since the visual should read more like wind, keeping just the dim glow ring at the dissolve front as the body shrinks tail-first with rising warp smoke. Now I'm starting to plan the sequencing for a new ROCK power, thinking through a cast gesture flow of aim, beat, then release.

For the rock power, the sequence is: he points at the target, a beat passes, then the rock rips from the ground and rises near his hand over 0.35s, hovers trembling in a warp field for 0.25s while he holds the pointing gesture (channel stays busy, aim tracks the target), then launches fast toward the target at 14 m/s with a small recoil kick animation on release. I'm settling on the ordering — point, beat, rock rises via telekinesis, then throw — since the attack effectively begins with the rock lifting off.

The rock itself needs to be a physical object: a rigid body mesh built from a randomly-generated convex rock shape (0.28-0.4m), lit and shadow-casting. During the rip phase it starts embedded in the floor about 1.2m in front of the lich toward the target, then rises to hover near his hand at roughly 1.5m height, kicking up a puff of dust and debris with a warp ring marking where it emerged from the ground. Then during the hold phase it hovers in place, trembling and slowly rotating, wrapped in orbiting warp effects.

For the throw, I need to calculate the launch velocity so the rock arrives at the target's body height following a straight path with a slight gravity arc -- computing flight time from distance and speed, then solving for the vertical launch velocity needed to counteract gravity over that time, while the rock spins and leaves a trail of warp puffs behind it. On impact, each tick checks for snakes within a crush radius near the rock's position and destroys them, with the rock losing some speed and continuing to bowl through more targets until it eventually bounces off the ground.

It continues crushing snakes along its skidding path with dust puffs at each ground contact until it slows down, rests for a few seconds, then sinks into the ground. For aiming, when the rock is cast I want to choose the throw direction by evaluating candidate rays toward the primary target and other nearby free snakes, picking whichever direction maximizes the number of snake bodies passing close to the ray within range, defaulting to the primary target on ties, and allowing multiple throws if capacity permits.

Now I'm working out the crush effect applied to a hit snake — flattening its body near the impact point with a falloff curve, pushing segments outward along the impact direction with decaying displacement and a twitch afterward, and sagging the head down.

For gore, I'm defining `gore.crush` to spawn blood drops in a fan pattern, meat bits, splash decals at the impact site, and mist particles, with the effect fading and sinking after about 3-4 seconds, including a variant for a crushed head. Given how much code this involves, I plan to write it in order: warp.js first, then the render hooks, then leak, then rock, then the crush function itself.

Now I'm planning warp.js, structuring streaks as a pooled mesh with paired vertices per point to form ribbon geometry, using rings as closed-loop streaks and puffs as point sprites, with attributes encoding neighbor positions, side offset, width, amplitude, chroma, and alpha envelope.

For the shaders, I'm computing screen-space width from meters via projection, expanding the ribbon outward along the perpendicular by half the pixel width; the fragment shader discards pixels behind existing depth, applies a gaussian-derivative displacement profile across the ribbon width, tapers intensity at head/tail with smoothstep, adds a sinusoidal ripple over time and phase, and layers a secondary tangential shift to simulate wind dragging the background, outputting displacement and chroma/alpha for additive blending into the render target.

Now I'm designing the puff particles: point sprites with size, amplitude, rotation, alpha, and seed attributes, where the fragment shader builds a radial falloff and a turbulent swirl-plus-push displacement driven by noise, producing a refractive blob effect with coverage based on falloff, alpha, and a fixed chroma value.

I'm working out uniform values like resolution, projection scale, time, and depth texture, making sure screen-space warp offsets align with the y-up UV convention, then sketching a simple API where a warp object exposes streak allocation for managing point arrays with width, amplitude, and other properties.

I'm designing the puff and ring systems next — puffs as internally-managed particles with position, velocity, life, and rotation, while rings reuse the streak mechanism with closed circular paths, settling on a shared point count of 24 for smoothness and pool sizes of 48 streaks and 400 puffs.

For material blending, I need custom blend factors (all "one") rather than standard additive so the alpha channel represents coverage without scaling offsets incorrectly, plus transparency with depth writes and testing disabled since I'll handle depth manually. Now I'm moving on to rewriting leak.js for the head streaks and flow.

For streak leakage, I want each trail to emanate from the skull and drift independently once emitted, computing its path by integrating a direction vector with rotational and vertical wave components over arc length, then precomputing a table of path points at fixed spacing so each frame can just interpolate the visible segment near the head.

I'm tuning parameters: streak speed, lifespan, and length scaled by reach, plus width, amplitude, chroma, and fade timing, along with an emission rate that scales with reach, and periodic floor rings spawning at the lich's position.

Now I'm working out dissolve smoke puffs spawning along the dissolving snake's front, with randomized position, velocity, size, and swirl, then adding a hook in snakes.js to trigger a respawn callback once the leak threshold is crossed.

I'm removing the old glitter motes at the dissolve front since warp puffs replace them, and reconsidering the glow ring shader for leakage — dialing it back so only the dissolve front glows rather than the whole body, tuning the intensity down for a smokier look.

Next I'll move on to rock.js, then gore.crush, then integrate the powers system to replace wind, and finally write warp.js.

Point sprite size limits depend on hardware but 96 should work fine. I'm verifying the streak vertex shader's pixel-space normal offset flows correctly into the warp composite, with x pointing right and y pointing up consistently through the coordinate transforms. Now I'm moving on to rewriting leak.js.

I need to make sure the leak context includes both warp and cave, since powers already carries those through. Before building the rock, I should verify the leakage effect is actually visible—checking camera frames of the dissolving snake and the head streaks for the subtle distortion.

I don't see any warp effect showing up here, and the leak detection is inconsistent — the until condition triggered once but later captures show none despite the snake presumably still being present. I should debug by reading back the rt_warp buffer directly after rendering to check for non-zero values, and also check the rt_world target.

I'll read the rt_warp pixels using the renderer's readRenderTargetPixels method, treating it as a HalfFloat target read via Uint16Array like the gem probe approach, then check the max absolute value to confirm the warp pass is actually writing anything.

Only 17 pixels show small offsets, barely any streaks written. I'm wondering if the depth test is discarding most fragments — maybe the depth texture's precision, given its format, is causing the comparison against gl_FragCoord.z to fail incorrectly.

Checking the streak vertex positions in world space and the fade amplitude calculation, those look fine, and warp.update is being called correctly in the tick loop. Maybe most streak fragments end up behind the lich geometry rather than in front, so they're getting occluded — I want to add a debug method exposing streak count, average alpha, and sample points to verify what's actually alive and visible.

I'm puzzling over why only 16 pixels are being written despite 25 active streaks—the vertex counts and index buffer sizes check out fine, so I suspect the issue lies elsewhere, maybe in how the ShaderMaterial is configured.

I trace through the matrix transforms and confirm the mesh sits at identity so that's not it. I verify the camera setup gets called properly in the render pipeline, and walk through the ripple/amplitude offset math to confirm the pixel offsets look reasonable. I keep circling back to the width calculation and the resolution uniform, checking that everything lines up with how the fx ribbons handle it.

Now I'm questioning whether the render timing between the warp update and the warp scene draw could be the culprit, but that seems fine since tick happens before render. I double check frustum culling is disabled and verify the vertex indexing for the quad triangles is correct, then start wondering if the issue is actually in when the render target gets read back after the final pass.

I also rule out the pixel count and streak thinness as causes since amplitude values look reasonable, and I verify the vertex attributes for position, side interpolation, and along-length coordinate are all set up correctly. I check whether the depth handling could be at fault, but the no-depth case gives identical results, so that's not it. Now I'm considering whether additive blending is actually working properly with the half-float render target.

Tracing through the streak allocation and update path, I confirm the point buffers are being written correctly from the streak's own array into the shared buffer at the right offset, so that's not the bug either. I'm now wondering if the issue is something more fundamental about how the shader material declares its built-in position attribute.

I want to manually place a streak with known geometry directly in front of the camera and verify its projected screen coordinates by hand, checking whether the points actually land within the visible frustum near the lich's position. That math checks out — the points should be on screen for camera 2 — so the geometry itself seems fine, which makes me suspect the strip expansion logic in the vertex shader, particularly how the w component is handled.

Rather than guessing further, I should just read back the framebuffer's alpha channel and count how many pixels have any nonzero value across channels, to confirm whether coverage exists at all even if it's faint or offset.

Only 18 pixels actually got touched even though the streak should span roughly 90 pixels on screen given the computed strip width and length. That suggests most fragments are being discarded somewhere, likely by a conditional check in the shader that's culling pixels rather than an actual rasterization limitation.

I'm tracing through the fade array and attribute update logic to see if vA (the alpha value) is coming out zero more often than expected, checking the position buffer writes and the per-streak parameter assignment for off-by-index errors that might be zeroing out coverage for most fragments.

Now I'm verifying the vertex shader's screen-space direction calculation, the width scaling, and the index buffer sizing against the vertex count to rule out a geometry issue before turning to whether the depth test setting is the actual cause.

I check that transparency and render targets aren't the culprit, then start wondering if the visible strip is degenerate because each vertex pair might be sharing the same side value instead of alternating, which would collapse the quad into a thin line.

Double-checking the varyings and attributes match between vertex and fragment shaders, everything lines up correctly. To actually diagnose empirically, I decide to add a debug uniform that bypasses the discard and outputs a solid bright color, so I can count how many pixels render and determine if this is a rasterization problem rather than a shader logic issue.

Only 18 pixels got rasterized, which points to degenerate geometry somewhere in the strip generation. I'm checking whether the points along each streak are collapsing to the same location, but the debug output confirms the head and tail points do differ after 120 ticks, so the issue must lie elsewhere.

I'm tracing through the buffer setup, index generation, and vertex shader logic — confirming the position attribute matches the updated array, the normal calculation for strip width looks correct, and the projection/view matrices should be available by default in three.js. Now I'm double-checking the width calculation to see if the pixel size threshold is somehow causing the strip to collapse to zero area.

I'm checking the render order between the warp scene and world scene, confirming the render target has no depth buffer and depth testing is disabled. I'm also verifying that autoClear and buffer persistence aren't causing the issue, and wondering if those stray 18 pixels are actually a streak visible on the floor ring.

Now I want to trace whether the vertex positions could be NaN — checking the path interpolation logic for out-of-range indices or negative tail values, and planning to dump the first streak's vertex buffer to inspect the actual position and param values directly.

The drawRange count serializes fine as Infinity turns into null in JSON, so the data itself checks out. That means the issue must be in the vertex shader's pixel-width calculation—I'm tracing through the math to see if the expansion logic is computing the right pixel size.

Testing with a fill mode that colors fragments red reveals only 18 pixels are rasterized, suggesting the triangles are staying nearly degenerate rather than expanding outward—so the side offset attribute likely isn't reaching the shader correctly. I'm checking whether the attribute name matches between the geometry and shader declaration, and verifying the uniforms object is set up properly across the shared materials.

Actually, I suspect the real culprit is backface culling: the material defaults to FrontSide, and depending on the winding order of the strip triangles relative to the perpendicular offset direction, some triangles may be facing away from the screen and getting culled.

The warp now writes 23k pixels with a max shift of 6.6px, and in still frames the effect is subtle—just slight distortion near rock edges around (560,290) and the egg region at (1000,340). Since stills can't fully convey motion, I'm considering a debug visualization that tints the warp buffer to show shift magnitude as proof of the effect.

The strength seems right at 6.6px max with mostly 1-3px shifts, and at the room camera the streaks will be thinner with ~2-3px shifts. Since stills don't capture it well, I'm thinking of rendering 60 frames at 640x360 and assembling them into a video with ffmpeg to show the leakage in motion, plus a debug visualization mode using a params flag to overlay shift magnitude as cyan. Now I'm moving on to write the rock throw logic in rock.js.

I'm working out the rock geometry — using a convex hull from random points in an ellipsoid shape, box-projected UVs sampling the cave rock texture, flat shading with a Lambert material, and defining the trajectory: a rise point in front of the caster toward the target, a hold point near the casting hand with lateral offsets per rock so multiple rocks don't overlap.

For the animation, I'm defining a "rip" phase (0.35s) where the rock bursts from underground, rising with an ease-out curve toward the hold point while spinning, triggering dust particles, pebble debris (reusing the dark chunk pool at smaller size), and an expanding warp ring on the ground. Then a "hold" phase where the rock hovers and trembles before presumably launching toward the target.

For the throw itself, I'm working out the aim logic: predicting the target snake's future position based on its movement speed and the rock's flight time, then checking for multi-hit opportunities by testing whether other snakes' spine points fall close enough to the throw trajectory within range.

I'll simulate the rock's flight with gravity and spin, leaving a warped wake of puffs behind it as it moves. Each tick I'll check for the nearest snake spine point to the rock and crush any snake within range, slowing the rock slightly on impact, and handle what happens when it touches the ground.

Rather than freezing snakes in place for the throw, I'll lead the target since the body is long enough that aiming with lead should reliably connect; I'll also widen the hit radius somewhat to guarantee a hit and prevent the snake from reaching the egg if the throw would otherwise miss.

To make this robust I'll add slight homing — the rock steers its velocity toward the target's current position during flight, like he's guiding it telekinetically, so the strike nearly always lands even with a moving target. For the crush/gore effect, I'm designing a blood-splatter system with fanned droplets and impact decals scattered around the hit point.

Adding meat scraps, mist puffs, and a crush effect that flattens the snake's body near the impact ring, kinks it along the strike direction, sags the head, and settles it over a couple seconds. I considered darkening the crushed flesh with a char effect but decided the color reads wrong, so I'm skipping that and moving on to the throwing gesture itself — the rise, hold, and release motion for the rock.

For the throw motion, I'm working out how the arm should behave: it holds steady until the release moment, then needs a forward snapping motion to sell the throw, so I'm settling on a small kick-based flick rather than a pull or full extension to keep it simple.

Now I'm figuring out rocks-per-cast using the same capacity formula wind used, positioning the aim ring at mid-body for the gesture, and swapping wind references for rock throughout powers.js—updating imports, the ALL array, HUD labels, and deleting the old wind file. Then I'll move on to writing rock.js and the crush logic.

The warp now shifts about 23,000 pixels, moving the world up to 6.6 px with visible wobble in the rock and floor edges around his head — I'll include a short clip since a still doesn't capture motion well. Moving on to the rock throw next.

Good, ffmpeg is available. Now I'll write the rock.js script.

I'm checking the offset calculation used for positioning, verifying it produces sensible alternating values, then looking at the aim logic during the hold phase and the crush behavior.

The rock's velocity homes toward the target by lerping toward a direct line while gravity still applies, so it curves into the target and then continues ballistically once it hits — stopping only when bounced and slowed. Now I'm sketching out the crush function in gore.js, which spawns blood and debris bursting outward along the rock's path with randomized speed and direction.

Adding splashes and mist puffs...

I'm also double-checking that MEAT_C is defined before the burst function uses it, and planning to swap the wind power for a rock power, updating the key label to "7 ROCK" and removing wind.js.

The cave's GI bake doesn't need updating since the return change doesn't touch geometry. I should also fix the outdated "wind" comments in the powers header to say "rock" instead. Then I'll test with rock only, capturing a couple frames through a throw and checking hit counts per throw while watching for errors.

The rock rises to 1.78m, holds, flies and hits its target, then the next cast can start with two rocks while the first is still in flight, since it's only busy until thrown. I want to check the frames to confirm this timing works.

The rock near the lich is too small to see clearly, so I'm setting up a closer inspection camera positioned between the lich and the rock's trajectory to get a better view of the throw.

I'm tracking the rock's motion, rising near his hand with a reddish-orange tint, then flying toward the snake by the egg and landing with what looks like a blood smear at the left. It seems the snake gets hit.

With that confirmed, I'm thinking through the throughput and guarantee logic — the rock replaces wind as the deterrent, since wind just pushed the snake away temporarily while the rock actually kills it by crushing. I want to run the full 20-case sweep and check the usage script pulls names correctly before doing a final leakage check and building a debug visualization mode for still frames, adding a warp-view toggle in render.js that blends in a cyan tint based on warp distance for debugging purposes.

The rock throw is working as intended, tearing from the floor, hovering, then flying to crush the snake. Now I'll add a debug view that tints the warped regions so the effect is visible in still frames, since a moving warp is hard to see in a single shot.

Looking at the warp view, the streaks curl out from the head and floor ring, while the dissolving snake's smoke puffs show up as small donut-shaped rings since the swirl offset is zero near the center — they're a bit small and sparse though.

I should make the dissolve smoke bigger and more billowing: larger sizes, longer life, faster rise, higher spawn rate, and stronger amplitude so the refraction actually reads. Since stills can't capture the warp motion well, I'm planning to render a short animated clip by stepping the game and capturing frames to show the effect properly.

Then I'll finalize the puff tweaks, run the full sweep and usage tests with the rock, gather evidence including stills, a leakage clip, and a rock-throw clip, and bundle everything up to deliver.

The warp effect works, but the dissolve smoke is too thin and sparse. I'll make it a bigger, billowing column and rerun the guarantee and usage checks with rock replacing wind.

I notice the r13c sweep mislabels the third power as "WIND" when it's actually ROCK—just a labeling mismatch, not a functional issue. While that runs, I'm sketching out clip plans: one for the leakage footage from camera 2, sampling every other frame for about 4 seconds, and another for the rock throw sequence from the inspection side view, covering the arc from aim to impact.

I'll skip a lens-fixed clip since it's not needed, but I want still frames showing warp view pairs too. I'm putting together an ffmpeg command to stitch the numbered frame sequence into an mp4 with h264 encoding, then upscaling 2x with nearest-neighbor scaling to make the details more visible at 1280x720.

I'm working through the timing math for the rock-alone-far scenario: distance of 11 meters, rise and flight phases, gesture time, arriving at roughly 2.1 seconds total before accounting for homing behavior — trying to reconcile this against the three known outcome counts (3 reached near, 29 reached far, 1 reached with all six).

Now I'm considering why far throws might fail at 29: possible latency from the rise/hold/flight sequence adding up to under a second, possible homing misses if the target keeps moving out of the hit radius, or possible early ground collision interrupting the flight before it reaches the target — since the homing steers in a straight line toward a low point near the ground, gravity could cause it to hit terrain prematurely and skid to a stop rather than completing its path.

The fix is to decouple homing so it only adjusts horizontal direction while recalculating vertical velocity each tick based on remaining distance and time, ensuring the rock always arrives precisely at the target height. I'm also double-checking rock capacity math and throughput timing look fine, and noting that wind previously just displaced targets while rocks now actually eliminate them — before investigating the "near all six" case further, I want to fix this trajectory issue first and rerun the sweep.

The rock alone let 29 snakes reach the egg because the throws were aiming straight and gravity pulled it short before impact. I'll fix the rock's flight path so it reliably connects, then re-measure hit/miss rates.

I'm still seeing failures in the near and far counts—hits plus misses don't add up to the total thrown, which suggests some rocks' targets got taken by other rocks before they could register a hit or miss.

For the far case specifically: the throw latency (rise, hold, and gesture time) plus travel time means the rock often arrives after the snake has already reached the egg zone. I'm thinking about speeding things up—cutting the rise and hold durations and boosting throw speed—plus engaging targets earlier so the rock has more time to intercept before the snake closes the distance.

For near-target misses, I suspect the issue is target collision: when one rock kills a target, another rock already thrown at that same target has nothing left to hit, so it just travels through and rests without ever registering a hit.

I want to fix this so best_line avoids re-targeting a snake another live rock is already committed to, and so a rock whose target dies mid-flight gets a fresh nearest-target reassignment at the moment it throws rather than locking in early.

The rock is still missing too often—near hits only 33/51, far hits 24/63, letting 15 snakes through—due to slow travel time, multiple rocks targeting the same snake, and rocks chasing already-dead snakes. I'll speed up the throw, launch earlier to account for travel time, and have each rock re-target a live, unclaimed snake right when it's thrown.

The fairness computation in the turn logic checks out, and the hold phase's aim point correctly returns the target's midpoint.

I'm checking the near/far results: near throws landed perfectly with no misses, while far throws still had one that reached the backstop. I want to trace that reached case through the reach_log to see why it slipped through, factoring in the gesture, rise, hold, and flight timing that adds up to the total latency for far throws.

Results improved: near the egg it's 33 throws, 36 hits, zero misses or breaches, while far away it's 40 throws, 39 hits, but 1 breach in the toughest case (11 m out, only ~1.25 s available vs. the rock's ~1.6 s flight time). I'll shorten the rise and hold phase for those emergency long-range throws.

Only 1 far snake reached, with 3 missed - I want to check the reach_log to see what was happening at that moment, like the claim state, and compare it against the director's state.

The "waiting for a render slot" message suggests a stale process from my earlier timed-out run is still holding onto Chrome/node resources. I should check running processes and kill any leftover ones tied to my project path.

I'm checking the render-slots directory and see slot0 is locked by pid 19216, but that pid isn't in my current node list, so I need to verify whether it's still alive or if Windows has reused that PID for a different process.

Those processes are all gone now — likely that earlier "waiting" state was just the prior killed run still shutting down. I'll rerun now that it's cleared.

I'm still puzzling over whether the pid check is giving a false positive since the process might not actually exist anymore, which would explain why it waited so long without ever getting a slot. Since these are just my project's scratch files with stale pids, I'm going to just delete the slot files directly.

So slot0 actually got claimed by that last run's PID, but it must have been killed mid-execution by the 580-second timeout before finishing — the probe is slow since it runs 18 evaluations of 300 ticks each with per-tick rendering.

I need to redesign the probe so it runs the logging logic inside a single `until` condition instead of triggering a render on every tick.

I found the bug: pooled rocks aren't resetting their `hits` and `torn` flags when reused, so hit counts carry over and torn rocks never dust again on their second life. I need to reset both `hits: 0` and `torn: false` when a rock is raised from the pool.

Now I'm looking at the timing gap at t=56.42 — the snake closed to 1.6m while the aim gesture was still pointing at it, and by the time the full sequence (aim → arrive → beat → flight) finished, the snake had already reached it. From 11m out, the gestured throw takes over 1.2s total, which is too slow once a threat gets urgent around 2.6m — I'm considering either pushing the rock's engagement range out to 5.5m or having urgent throws skip the arm gesture entirely and yank a rock straight from the ground near the target.

I'm ruling out the idea of a rock erupting from beneath the target since a proper throw needs visible flight, so instead I'm bumping the quick-throw speed to around 22-24 m/s and tightening the aim phase to 0.45s max for urgent cases. I'm also checking the cooldown math (0.83s per rock) and tracing through the state logic for what happens when the hand is mid-channel holding a rock but there's no extend action available — making sure urgent snakes don't get stuck waiting on a busy channel with nowhere to go.

I found the issue: the throw was triggered too late since the rock only engaged at 11 m, plus a bug where reused rocks kept stale hit counts and skipped tear-out dust. I'm fixing this by dropping the engage range to 5.6 m, speeding up emergency throws, and adding an instant extra throw when a snake is about to reach the egg while a rock is held.

Rock alone shows solid results with both near and far throws, just a couple missed reaches on far. Now I'm setting up the full 20-case sweep plus usage runs together, planning to run them sequentially in the background since the combined command held up earlier.

Rock's performance so far: 36/40 hits near the egg with no misses or reaches, and 40/41 hits far away with 2 misses. Now running the full 20-case sweep and usage check with rock included.

While this runs, I'll draft the RECORD entry for round 23 and prep the clip scripts, then update ANCHOR_PORT.md to note that Anchor lacks a grab-pass equivalent for the warp buffer's distortion effect — it'll need a float render target with signed additive blending plus depth texture sampling in a custom pass.

The sweep shows the 'far all six' case reached 1 while usage stayed even at 0, so I want to figure out which power triggered that. I'll rerun the far-all case with logging enabled for 90 seconds to inspect the reach_log and director state directly.

From a fresh page load with the same setup, this run showed 0 reached and no near events, unlike the earlier sweep where the far-all case came after 10 prior near cases with carried-over state (snake positions, gore, etc.). This suggests the failure is state-dependent and possibly rare, so I want to replicate the exact sweep sequence starting with the near cases to see if it reproduces.

I notice the reach event at t=900.33 lines up right at the boundary between test cases — that's just as the "far-all" case begins (case 11, starting at t=900). It looks like a harness artifact: a snake that was already 1.3 m from the egg carried over from the previous "near none" case, so when powers switch on at t=900 it immediately reaches the egg at 900.33 rather than reflecting genuine behavior under the new condition.

Now planning the evidence package: a lens comparison (before/after numbers, no image needed), live lift-pull numbers, a leakage clip (camera 2, 4 s) plus warp-view stills, and a rock clip (side inspection + camera 2) plus stills. For rendering, I'll generate frames for the leak clip (120 frames) and rock clip (84 frames each from side and camera 2 angles), each at 640×360, then assemble into mp4 via ffmpeg at 30fps with 2x nearest-neighbor upscaling — estimating a couple minutes per clip. I'm also considering whether the leak clip needs a warp-view version or just stills alongside the normal footage.

The one reach happened in the first 0.3s of a case where a snake starting 1.3m from the egg arrived before any power activated — an artifact of the sweep switching cases, not a real guarantee gap, since every other case shows 0. Now I'll render short clips demonstrating the leakage and the rock throw.

I should check a few frames from the rock side and leak clips to verify their content, sampling roughly every 10th frame in a tiled view.

Tracking the rock clip, I see it rise, get held, then thrown flying left before disappearing from frame — the crush itself isn't visible since the target seems out of view. There's another rock visible near him later, but this angle isn't great, so I should check the second camera's rock frames for a better view.

Looking at camera 2's footage, I notice the rocks land near the front but the actual crush moments happen off-frame in the dark. To capture a crush clearly, I'd need to position a target snake in view between the lich and the camera, maybe using a tracking camera that follows the rock through its full flight and impact.

I'm planning a fixed side camera centered on the midpoint between the rock's launch point and the target, positioned by waiting for the rock's "hold" phase, computing the target and hold positions, then capturing frames through flight, impact, and one second after. Since the debug output only shows phase, hits, and coordinates, I need to expose the target midpoint position in the debug info too.

Neither clip captures the actual crush moment—it's off-frame or too dark. I'll re-shoot with the camera positioned at throw time, side-on to the rock's flight path and centered between the rock and snake.

I'm puzzled why the until condition only returned a single value instead of the expected array, and suspect the evaluation errored partway through - possibly something in how the game object's debug function gets called within the generated function context.

I see the crash is because the setc watcher never found a held rock within range before timing out, leaving that value undefined when cam reads it. Since the rock actually engages around 5.6 m, I should loosen the distance threshold to under 5.0 and add a guard in cam to handle the undefined case safely.

I'm picturing the sequence playing out: the lich at left, the rock crushing the snake at center with a small dust and blood splash, dark but visible in motion. I'll plan to deliver a few clips—leak.mp4, a side-on crush shot, and a second camera angle.

I'll swap the old rock.mp4 for this new rock3 clip by encoding it and replacing the undelivered previous version, and also prepare still warp-view images for the leakage sequence.

I also notice those console "toNonIndexed" warnings — since ConvexGeometry is already non-indexed, I should just remove that redundant call in rock.js to keep things clean, then rebundle.

The sed command failed because the replacement text had a slash in it, so I'll switch to using the Edit tool instead.

I'm thinking the hand should visually track the rock like it's controlling it, and the rock's motion should feel more organic — drifting, wobbling, overshooting slightly, with imprecise starts and stops instead of rigid kinematic phases. I want to replace the current lerp-based rise, fixed hold, and instant-velocity throw with something driven by physics-like forces.

For the rip, I'm picturing an initial upward impulse pulled toward the hold point by an underdamped spring-damper, with added low-frequency noise so it wobbles a bit before settling into a bob after about 0.4 seconds. During the hold, the target drifts slowly so the rock floats and bobs naturally rather than sitting static. For the throw, instead of snapping to a launch velocity, I want the "mind" to accelerate the rock along a pursuit path toward the snake with a ramping acceleration limit and sideways noise for aim imprecision, plus a slight windup where the rock drifts backward before launch.

On impact I don't want it to stop instantly — it should continue with bowling-style bounce physics, and the mind only releases control after the hit, after which it goes ballistic. I also want to fix the flat trajectory by adding an arc (rising slightly after launch then diving down onto the snake, height proportional to distance), and make the tumble's angular velocity increase gradually instead of staying constant. The hand should keep tracking the rock as busy all the way until it hits or lands, not just until it's thrown, and when there are multiple rocks it should follow whichever one is still in flight.

For timing, I'm working out acceleration curves — with roughly 55 m/s² reaching 17 m/s in about 0.31s over 2.6m, a 5m throw takes around 0.45s versus the current instant 0.3s, which is slower but adds the needed arc; urgent casts should get higher acceleration. I'm also noting the hand being occupied longer will eat into throughput for other gesture-triggered powers, adding about 0.4s per rock cast, so I need to verify this doesn't cause fairness issues through sweep testing. Now I'm sketching the rewrite of the rock update logic, tracking position, velocity, target point, and phase per rock, with a controller force pulling toward the target.

Defining phase-based physics constants...

Shaping the arc trajectory with horizontal velocity ramping under acceleration limits and vertical motion following a parabolic path toward the target, blended with a lookahead PD controller and added lateral noise for imprecision.

Once a rock hits, control ends and it becomes ballistic, letting gravity, ground bounce, skid, and rest take over. I still need to handle retargeting if the intended target dies mid-flight, and add rotation dynamics — slow tumble during rip/hold, ramping to fast spin during flight — plus logic for the hand to track and follow whichever rock is currently active.

I'm reworking the rip/hold/fly update phases to route through a mind-controller helper that drives values with spring-like overshoot and eased acceleration, so the motion feels intentional rather than instant.

Rip breaks upward with a quick initial velocity boost then eases toward the hold position, with a faster "quick" variant that transitions sooner and pushes harder. Hold adds subtle wobble drift and a windup pullback just before release, while fly computes the throw velocity the mind imparts to launch the object outward.

Actually velocity control seems simpler: accelerate toward a desired velocity combining horizontal speed and a lookahead vertical target on the arc, with some added lateral and vertical wander for imprecision. Once it hits, control turns off and it goes ballistic; if it hasn't hit within 1.2s, release it too, retargeting mid-flight if the original target dies.

For rotation I'm setting random-axis spin that ramps up during flight, with aura puffs during the rip/hold phase and a wake trail once flying. The launch gesture should be a smaller flick rather than a big kick, with the hand tracking whichever controlled rock is active and timing budgeted across the rip, hold, and accelerating fly phases to total roughly under a second.

Now I'll write the actual code implementing this.

I'm double-checking that the replaced block in the fly branch still flows correctly into the wake puffs, hits, floor, and rest-phase checks that follow in the original code.

I'm also verifying the floor-collision logic applies correctly while under control (bouncing near ground level and damping velocity), the spin convergence function, the phase-based axis vector, and the ra-related hold logic in the rip branch.

I'm tracing through the hold-to-fly transition, the y-position formula that blends toward the target arc, the kick timing during throw, and confirming the hand consistently follows the rock's position as the aim target, with hit detection only active during the fly phase.

I'm checking that the wander function's shared vector is reused safely in sequence across hold_on and spin without conflicting writes, since it's called with the same buffer in both places.

Now I need to confirm the body's facing rotates toward the rock so it stays in view, then run stats and a test clip to validate the near/far behavior.

The rock-only stats look solid — near-range 36/33 hits with zero misses, far-range 40/38 with just one miss. I want to check motion quality too, examining trajectory smoothness and jerk/acceleration per tick, plus reviewing a side-on clip and second camera angle from the r23_clip_rock3 scenario, tracking the rip-hold-fly phases with debug target info.

Hit rate stays strong with the new motion—near-egg throws landed 33/36 and far throws 38/40 with 1 miss, none reaching the egg. Now checking the path itself for abrupt starts/stops and re-shooting the side-on clip.

I notice the positions are rounded to 0.01m, which makes the derived accelerations quite noisy from quantization alone. Looking at the speed profile, the rip motion shows a smooth rise from 4.8 to 7.5 before decelerating down to 0.6, then a slow hold, followed by the fly motion accelerating smoothly from 0.6 to 18 over about 0.4 seconds.

Now I want to re-shoot the side-on clip using the camera position computed at hold time, triggering it through the rock3 script that fires when the hold condition and target proximity within 5.2 are both met.

The speed profile now looks smooth: breakout at ~5 m/s, deceleration into the hold, a float, then gradual acceleration from 0.6 to 18 m/s over ~0.4 s rather than an instant jump (the noisy acceleration numbers are just an artifact of 1 cm position rounding). Now re-shooting the clips to check how it looks visually.

I'm mapping out the rock's motion frame by frame — tearing free, rising by his hand, then arcing down to crush the snake, followed by two new rocks rising for the next throw. Now I need to encode these clips into the round page along with the guarantee and usage details.

The rock tears out, floats beside his hand, then tracks down to crush the snake, with the next throw lifting two rocks at once. I'll encode the clips and run the guarantee and usage checks, since his hand stays occupied longer per throw now.

I'm not sure if running that command with & backgrounded it properly, since Git Bash's handling of background jobs after shell exit is uncertain. I should check whether it's actually still running.

While that runs, I'll write RECORD round 24, then after the sweep finishes run usage, bundle everything, and deliver it.

I'm noticing the ROCK measurements in the sweep don't match my standalone reading of zero, which makes me suspect these are transition artifacts carrying over from whatever case preceded them rather than true readings for rock itself.

The sweep shows the rock alone is still marginal, with results inconsistent with my fresh single runs, likely the same case-switch quirk as before. I'll replay the sweep with logging on the rock-alone case to investigate.

I'm noticing a conflict: an urgent snake is close to the egg, but the hand is occupied with the rock channel, so I'd normally handle it via a quick extend action. However, the extend gets blocked because that snake is already claimed by the current gesture's targets — meaning this urgent snake is actually one of the rocks currently being cast.

The fix is to make individual rocks speed up when their assigned target becomes urgent mid-channel, rather than only checking urgency once at gesture start. I want to check at raise and on each tick whether the target's distance to the egg has dropped below the urgent threshold, and if so, flip that rock into a faster rip/hold/fly sequence dynamically.

Running the timing math, the accelerated quick path (~0.6 s from the urgency trigger) is marginally faster than the snake's remaining approach time (~0.85 s), so it should just barely work — though I should double check whether "reached" is measured against the snake's head or the mid-body point the rock is actually aiming at, since that offset affects the margin.

Let me actually implement this and rerun the sweep-order trace for the near-rock case alongside the standalone test.

Found the issue: a rock keeps its slow, unhurried timing even when its target snake reaches the 2.2 m danger zone while it's still rising. I'll make rocks switch to emergency timing mid-flight—shorter hold, harder push, faster—whenever their snake gets close.

I'll run the full sweep in the background and check the usage afterward, watching for that "far all" transition artifact again—I'll accept it if it lines up with the timing around t≈900.x.

The clips were rendered before the hurry change, and since hurry only affects urgent cases, the normal throws shown are fine to keep. I'm also considering a harness fix for the sweep's transition artifact—maybe adding a warm-up step before recording each case, or resetting the snakes at case start—though I need to make sure it doesn't break comparability.

I'm reconsidering the rock: maybe it shouldn't need the hand to point or follow at all, since it moves by telekinesis from the mind alone. That would put it in a different category than gestured objects like the lens, potentially running on its own parallel schedule rather than sharing the hand's rotation.

For the snake reaction to the rock hit, I'm thinking the crush effect currently just kinks and flattens it in place, but a truly physical response would have the impact impart momentum — the body should get knocked and thrown along the rock's direction rather than just twitching where it is.

I'm working out a verlet rope simulation for the snake's spine: 72 nodes preserving segment lengths, with a few constraint iterations for stiffness, ground collision, and friction, so it tumbles, coils, and settles naturally. The impact would inject velocity into the nodes near the hit ring, falling off over a range of neighboring rings, with the existing flattening/blood effects layered on top. Now I need to figure out how to feed these simulated rope positions back into the snake's rendering pipeline, since the spine is normally built from trail and lift/shift data.

I'm adding a hook in the build function so the fx system can directly override each computed spine position with the rope's simulated position, letting the physics take full control of the body placement while the tube normals still derive automatically from neighboring points.

When multiple snakes get hit by the same rock, each spawns its own independent rope simulation, and the rock continues losing 22% of its speed per hit as before. After death, the rope physics runs until it settles (~2 seconds), then the fx handles sinking by gradually lowering the positions before marking the snake done around 3.5 seconds.

Now I'm working out the rope node details: storing current and previous positions per node, rest lengths from the spine distances at impact, gravity, air damping, ground contact and friction handling, plus a bending stiffness term.

I'm adding a weaker secondary constraint linking every other node so the dead body keeps a bit of natural curve instead of going completely limp, applying an impulse near the impact point that fades outward and gives an upward kick, running a few solver iterations per tick since the node count is cheap, adding small decaying random twitches to mimic nerve spasms, and starting the sink effect after about 2.2 seconds.

Now I'm reconsidering the dissolve direction, since the current tail-to-head fade looks wrong and needs reversing so it reads as dissolving from the outer extremities inward instead.

Actually maybe it's about proximity to the lich: the tail is typically the far end from him, so dissolving tail-first means outward-to-inward toward him. Reversing that would mean the end nearest him dissolves first, spreading outward along the body — which makes more physical sense since the leakage originates from his position.

I should also make the dissolve visually striking, keeping with the established prismatic-warp, color-coded language — maybe having the body break into flakes or fragments right at the dissolving edge.

The skin could peel into shards that float upward, turning from the snake's natural color into shimmering prismatic warp-smoke as they rise, like ash but iridescent. Ahead of the dissolve, a band of opal-colored glow could spread through the flesh — the body briefly crystallizing into the lich's gem-like bone material before crumbling into flakes, giving a "crystallize then shatter" progression.

Implementing this means a new instanced flake pool of tiny quads that start olive-colored like the snake, then lerp toward opal/prismatic tones as they rise and swirl away.

For the flakes' motion: curling drift, tumbling rotation, and a shrink/fade before they vanish into a small warp puff, roughly 10 per second per dissolving snake.

For the head streaks, I want to make them a touch more visible and prismatic — boosting amplitude and chroma split by about 1.3x, widening slightly, and adding a faint coverage-based haze brightening so the overall effect reads as brighter and more shimmering without going overboard.

Now I'm reconsidering the haze intensity and thinking about tinting the streaks with a subtle hue based on screen position, though the warp buffer doesn't carry hue data directly, so I'll settle for stronger chroma splitting plus a slightly higher coverage brightening just for the streaks. I also need to make sure the rock element stays non-gestured but still participates in rotation, and I'm sketching out the power logic for it — checking active threats, excluding already-claimed ones, and capping the engagement count similar to how the lens logic works.

For urgency handling, I'm giving rock the same quick-fire treatment as the lens for urgent threats when hands are busy or the player is alone, but adding claim tags like 'ROCK-QUICK' so the lens and rock don't both target the same urgent snake — each rush filter needs to exclude targets already claimed by the other's quick-fire claim.

I'm also working out positioning without a hand: the rock should rise centered in front of the character rather than beside a hand, using the target's side to determine offset, and I'm adding a LOOK glance so the head tracks toward the rising rock similar to the lens behavior. The facing constraint stays loose since pointing alone shouldn't force a turn.

Now I'm moving to crush_fx and rope physics, then writing the placement hook in snakes.js — after setting each position in build(), I'll call `fx.place(i, P[i], s)` if it exists, so I need to check the build code near where P gets populated.

I'm reworking the leak dissolve logic so rings vanish outward from whichever ring point is closest to the lich, instead of from a fixed end, which means I need to track and fix an origin ring index per snake once its leak begins.

This splits the snake visually into a gap that spreads from the middle, since the piece nearest the lich dissolves first while both head and tail ends persist longer — I'm now second-guessing whether this actually matches what he meant by "outwards to inwards," since the viewer's sense of "outward" might really refer to the tail end receding from the lich rather than the literal spatial middle.

For the visual effect, I want a prismatic crystallization band ahead of the dissolving front, turning the flesh into shimmering opal-like light, and having the body break into small instanced flakes that lift, swirl, and dissolve into warp puffs. I'm setting up an instanced flake pool using a flat circular/diamond plate geometry with emissive material...

I'll go with unlit flakes using MeshBasicMaterial, transitioning instance color from a dark skin tone to a bright opal glow as they rise, then shrinking away with a small warp puff, generating roughly 20 flakes per second per dissolving snake while adjusting streak amplitude, chroma, and coverage for the effect.

Now I'm working through the rope physics for rock impacts, wiring a `place` call into the snake build step so each rope node writes back into the spine array, then checking the update loop ordering to make sure the rope integrates via `fx.tick` before `build` reads the updated node positions.

Sketching the crush effect: I'm setting up spine point clones as a Verlet particle system, precomputing rest-length distances between neighboring and next-nearest nodes, then applying a directional/upward impulse weighted by proximity to the impact index to kick off the initial displacement before the tick loop integrates velocities each frame.

I want to pass the rock's velocity vector into the crush effect on impact. Checking eye and radius placement look correct, and with 72 densely-packed verlet nodes (as small as 1.4 cm near the head) and 4 iterations, the simulation should stay stable. Crushed snakes are excluded from further hit checks, all touched snakes get fully crushed rather than just pushed, and the gore/blood effect stays as is.

Now I'll write out all the edits.

I'll flip the dissolve direction so it starts at the point nearest him and spreads outward, with flesh going glassy before flaking into rainbow shimmer at the edge—let me know if that's not what you meant. Starting the code now with the rock-hit physics.

I'm checking the lens logic for `lone` and verifying that both the rock rescue condition and the cast function signature are correct, then moving to inspect the raise function's argument handling.

Now I'm planning the leakage effect changes: tracking where a leak originates on the snake, having it spread flakes bidirectionally toward both ends, and adjusting the streak/haze rendering intensity. I'm working out the math for computing distance from the leak origin ring to drive the crystallization gradient and glow intensity along the snake's body.

Writing leak front logic...

I'm bumping up streak coverage and haze density in warp.js, and confirming the chroma clamp keeps values within a sane range.

Checking the leak context includes R and that powers context is correct — looks good. Confirming the snake alias names line up properly, and verifying that flake matrices get scaled to zero exactly once when their life expires rather than repeatedly.

I made sure update_flakes runs alongside update_streaks and update_rings before the early return check, so it always executes regardless of state. Now I'll run through the edits and do a syntax check.

I should visually check the rock hit physics with a side-on clip and the leakage dissolve close-up, plus gather numbers for rock-alone tests near and far before doing a full sweep. The condition check for the rock3 clip script still looks valid, so I'll run the side-clip test and review the resulting frames.

The rock side clip framing is poor—the impact area isn't visible and it's too dark to judge the physics well, so I really need a better test with numeric tracking of the struck snake's displacement, peak height, and rest position, plus a clearer close-up of the impact itself. Meanwhile the leak dissolve close-up shows the dark snake with a bright rainbow glassy band across its body and some flaking detail.

The bright glowing flakes are reading too much like the glitter dots he explicitly moved away from, so this is drifting back into the aesthetic he wanted to avoid. I think I should make the flakes darker with just a subtle prismatic sheen rather than glow, and have each one dissolve into a small warp puff instead—applying that to all the flakes, not just a portion—while also toning down the brightness and glow intensity of the rainbow band so it doesn't overwhelm the effect.

For the rock physics, I need to check the struck snake's hit ring position before and after impact, measure node height and whole-body movement, and add debug exposure for the last crushed snake's spine data.

I found two issues: the side clip missed the rock hit, and the dissolve flakes/glassy band look too glittery and neon. I'll film the knocked snake's motion directly, tone the flakes to dark skin with faint sheen and warped air, and shift the band closer to the bones' pastel with more warp smoke.

The struck part of the snake likely jumps up to around 1.0-1.26 m within 0.4 seconds before settling, while some other point along it stays essentially fixed at zero displacement since the rope constraint anchors that end.

Now I want to re-render the close-up clips — one for the dissolve and one for the rock impact — with the camera tracking the struck snake. I'll trigger the camera at the moment the rock enters its flight phase, positioning it near the rock's target with a fixed yaw and pitch so the throw is visible as it happens.

The numbers match a physical knock: the struck part launches 0.4–0.5 m high and 1.0–1.3 m along before settling in about 0.4 s, while the far end stays nearly still like a limp body. I'll film it close up with the camera fixed on the target as the rock is thrown.

That hit clip attempt failed since the wait condition couldn't find a 'fly' rock with a target within 4.5 meters, and the distance limit was too strict given rocks can target up to 5.6 meters away—I should drop the distance constraint and just look for any fly with a target.

I'm checking the rock-hit clip against the snake — it's a subtle collision but the motion reads okay in the dark scene. Looking at the leak dissolve now, the glassy band still looks too neon and bright, and I'm trying to figure out what those small colored dots scattered through later frames actually represent.

I'm checking whether the flake colors will actually read as bright given my current exposure and opacity settings, since the low exposure value combined with the additive blending math might wash them out too dark.

Thinking about the owner's feedback though — the glitter-dot look isn't what they want, they'd rather this feel like wind. So I should dial the flakes down to a subtler skin-toned sheen rather than colorful specks, and let the warp puffs carry the sense of movement instead. I'm also noticing the rainbow tail band spans a huge chunk of the body — roughly 30% — which is way more vivid and extensive than intended.

I'll shrink that band significantly and tone down its intensity so it reads as a subtle glassy sheen rather than a neon strip. Given the skeleton's pastel, understated bone tones, a saturated rainbow feels off-brand — I'll aim for a softer pastel glassiness near the edges instead, adjusting just the glow parameter rather than touching the core shader logic.

The flakes and glassy band are overexposed, making them look like a neon rainbow tail rather than a subtle sheen. I'll darken the flakes to a skin tone with just a hint of color and shrink the band to a short, subtler edge highlight.

I'm refining the tail's edge to a subtler prismatic glassy look, with the flakes reading pale grey-white and chromatic fringes from the warp effect splitting light around them—giving an overall sense of prismatic, wind-like air distortion around the dissolving debris.

This composition works: debris swirling upward into rainbow-fringed, warped air. Now I need to encode the clips, run the sweep and usage check since the rock's rotation has changed without a gesture applied, then bundle everything up for delivery.

I'll refine the effect with a subtler glassy edge and rainbow-fringed flakes instead of glowing confetti, then encode the clips and run the guarantee and usage checks to account for the rock no longer using his hand.

I'm redesigning the prismatic beam kill effect: instead of the snake shattering into prismatic shards and glitter, I want it to burst into violent, chaotic streaks of transparent prismatic warp radiating outward with warp smoke puffs, plus a touch of gore like scattered blood drops and small meat bits.

Now I'm working out the parameters for the burst—count, speed, curl, lifespan, and amplitude for the streaks and puffs, alongside a light gore layer of blood, meat bits, and mist using the existing gore module functions.

The bite sparks stay separate from the glitter explosion since they're part of the accepted beam behavior, like the lens beam sparks. For gore.js, I'll add a spatter function that generates drops radiating from hit points, plus meat chunks, scraps, a splash at the body center, and mist particles.

I'm checking that create_beam properly destructures the context object, including the warp, gore, and cave properties. Now I'm planning the warp.fling function, adding an internal flings list that gets updated during warp.update with a precomputed path.

I'm worried about the streak pool size — with the beam chain killing up to 8 snakes and each kill spawning 26 fling streaks, that's 208 streaks needed but the pool only holds 110, meaning later flings would get dropped once the pool is exhausted.

I want to capture a beam kill closeup too: hold on the beam alone until a pierce triggers, detected by a snake showing fresh glow fx with a small elapsed time, then snap the camera near that snake and sample frames every 2 ticks over 1.2 seconds for the clip and still frames, positioning the camera near the snake at a 3m distance and 25-degree pitch.

I'm tracing the beam and snake sequence frame by frame — the snake glows white then lifts as the beam bites in, sparks scatter at the burst but the warp effect barely reads in stills, and afterward the snake disappears with faint dark red blood drops on the floor through frames 24-36.

Let me check the warp-view frames to confirm the flings actually show up.

Looking at f_011 in warp view, I can see the burst producing a cluster of teal tangled streaks around the snake, but they're fairly compact at 0.5-1m when they should fly further given the speed and lifetime parameters — closer to 1.5-6m based on the math.

In normal view the effect is subtler in stills but should show in motion. To make it "more aggressive and messy" as requested, I'll bump the amplitude to 7-10px and chroma to 1.3-1.6 — it's only a brief 0.5s burst so a bit garish is fine. I'm also checking the pre-burst glowing white snake fill stage and the glittery spark motes tied to the beam's bite during the fill phase (f_003-009).

The sparks were already accepted in earlier rounds, so I'll keep them as-is. Now I'll re-render with the increased amplitude at both normal 30fps and a slower half-speed version covering the 40-frame window from fill through burst.

The warp view confirms the burst effect works, but I'll push the bend and colour split further for more aggression, and add a half-speed clip since the burst only lasts half a second.

I should check a few frames of the slow clip in normal view to spot the burst, since the warp might show up as distortion around it. Let me look at frames 16-28 at full resolution, cropped in.

I can see the background bending near the burst point in f_008, with the beam warping into a rainbow-tearing distortion, and the ground looks subtly warped in f_012-016 with blood splatter appearing by f_020. The effect looks confirmed, so I should move on to the guarantee sweep, keeping the beam mechanics unchanged since only the death visual is affected.

Since there's no director change, I can skip the full sweep — a quick 60s all-six run should be enough as a smoke test just to catch any errors, not a behavior check.

The half-speed frames confirm the beam and floor now show rainbow tearing at the burst with a blood splash left behind, while kill mechanics remain unchanged. Now running a quick all-powers smoke test for errors before bundling.

I'm noticing the usage counts aren't evenly distributed—FIRE, LIFT, and ROCK show only 2 each while BEAM is at 15, suggesting the counter carries over rather than resetting, and that the low cast frequency in the first 30 seconds makes sense given fewer snakes were nearby early on.

Reached zero, so time to record the result and deliver it.

I want to amp up the gore on the beam burst significantly—more spatter drops, meat chunks, body pieces, and a bigger splash effect. I'm also rethinking the ricochet mechanic: instead of the beam bouncing, I'll have multiple beams fire simultaneously from the same fingertip toward separate nearby snake targets.

For implementation, I'm setting up each target to get its own curved beam segment from the fingertip that bends toward its hit point, staggered slightly so they fan out visually, with a cone limit (~±40°) restricting which targets qualify—anything outside gets excluded and released for another gesture to handle. I'm also planning the firing recoil kick that happens at the moment each beam launches.

Now I'm working through how urgent extensions mid-channel should behave: a new beam can be added to an urgent target only if it falls within a wider cone (±55°), otherwise the extend call fails and the hold continues without it, risking the urgent threat going unaddressed. I'm deciding that a failed extend should be tracked as a refusal flag, and treating a channel that's busy refusing an extend the same as a busy hand for purposes of triggering the lens/rock rescue mechanic.

I'm running timing calculations: solo beam at power 6 gets roughly 8 beams per cast with a 0.9 second cooldown, and I'm estimating the total wait an urgent snake would face if it's outside the cone -- channel duration around 0.5s plus chaining into the next gesture -- landing close to but under 1 second, which is borderline against how long a snake at 2.6m would take to become dangerous.

If urgency refuses the extend, I want the channel to end early by skipping the dwell phase so the hand frees up sooner. I'm also confirming the aim point during hold locks to the primary target, and noting the design intent: the lich should only split a beam across multiple snakes when multiple threats actually require it, which the director's target list already enforces.

Restructuring the beam logic to fire parallel beams instead of chaining them sequentially...

Still writing beam state logic...

I'm restructuring the ring-hit logic to support multiple beams, replacing the old section with new helper functions for bite damage, kickback, and target resolution.

Now I'm setting up per-beam state so each snake fires one beam from its fingertip, with fan spread angles and a wait/shoot/burn phase cycle, and handling edge cases like a beam fading if its source snake gets taken before it lands.

Adding burn sparks and cast logic...

Adding chain-extension logic to let new targets join mid-cast if they're close enough to the primary angle, plus a release function that frees unburned beams and fades others, and exposing busy/aim/chain helpers so the hand tracks the primary beam.

I'm now working out an edge case in powers.js: when extend() is refused for a solo beam (no rescue via lens or rock available), figuring out whether the hold should force an early hurry() on the beam or let it complete its short burn cycle before releasing the channel.

Timing-wise it looks tight but workable — the beam finishes its kill before the hand needs to disengage. But I'm also realizing since beams are drawn live from the fingertip each frame, moving the arm mid-burn would visually drag the beam toward the new target, since the kill point is already fixed while the source keeps moving.

Better approach: instead of releasing the hand early, fade all beams immediately on refuse (~0.22s), letting already-pierced snakes shatter on their own while unhit ones are freed. That frees the hand fast enough to fit the quick gesture and urgent snake within the ~1s budget. I'm starting to sketch out the power-change logic for handling urgent snakes.

I'm bumping up the gore values across categories — drops, meat, scraps, splashes, and mist — to intensify the effect.

I need to write the tail file first, since the script failed before writing—the read failed before the write happened, so the file remains unchanged as expected.

I need to add get_L to the destructured context variables in create_beam, and clean up remaining references to the old chain/targets pattern elsewhere in the file. I should also update the header comment mentioning BOUNCE to reflect the current round's changes.

I should test the beam alone at power 6 with capacity 8, checking how many beams get cast within the fan and capturing a multi-beam fan visually from a second camera. I also want to sweep the guarantee to see how beam changes affect the director.

Most casts end up being single-target beams since the fan restriction near the egg limits multi-target hits when snakes surround him from all sides. With aim, channel, and hold time combined, each cast takes about 1.5 seconds, giving roughly 40 casts per minute.

I could shorten the channel time — instead of holding the beam until it fully fades, I could let it detach from the finger once it's burned into the snake, cutting the dwell down to about 0.4 seconds total. I'm also considering widening the fan angle during urgent moments to catch more targets at once.

Still, 3 snakes are getting through, likely because urgent threats appear from another side while the beam is holding — I want to apply these two changes and re-measure.

With the beam-only approach, 3 snakes got past the egg (up from 0). I'll fix this by having beams hold briefly on their target before the snake bursts on its own, and by widening the fan to about 50°, without reintroducing ricochet.

Now I need to catch a multi-beam fan cast — waiting until at least two beams occur so I can grab shots from camera 2 plus a side angle, along with a close-up burst of the gore effect. Then I'll kick off the full sweep and usage check in the background.

I'm not confident this view captures both beams clearly since they seem to overlap in direction. I'll switch to a steeper overhead-ish angle, pitch 60° at distance 6, centered near the lich, and keep trying casts until I find one with at least 3 beams for a clearer fan visualization.

Something seems off with the overhead camera framing — the lich doesn't appear centered, and the pool with the egg looks like it's positioned off to one side with the beam. I'm noticing what might be two separate beams running from near the pool edge toward the right side of the view.

Given the effort I'm putting into these visuals, I should switch to a cleaner setup: track camera 2 (the in-game view) during a moment when the lich casts three beams at once, positioning the lich further away so all three beams are visible together.

From far away, camera 2 would show the three beams overlapping into what looks like one thick beam since the targets are roughly in the same direction — the fan effect only becomes visible when targets are spread apart. The demonstration footage isn't ideal proof on its own, so it's probably better to focus effort on giving concrete numbers plus a clip showing two beams diverging clearly, rather than staging something more elaborate.

Running the full guarantee sweep and usage check now.

I could also render a close-up burst clip to emphasize the gore increase using the existing burst asset, but since the render slot is already occupied by the sweep job, I'll queue it and wait rather than compete for the resource. In the meantime, I'll write up the RECORD entry for round 27.

That's likely just a case-transition artifact again, so I want to fix the harness seam properly this time: I'm modifying the sweep so each case gets a 3-second settle period with the new power values before measurements start counting, resetting the reference state after the settle to eliminate the artifact for good.

I found the guarantee holds at 0 everywhere except the all-six-far case, which sits on the same edge as the no-powers scenario. I'm adding a 3s settle time before counting starts in each case and rerunning the sweep to confirm.

With the sweep settled at zero, I'll now render the gore burst close-up clip and the two-beam fan from camera 2 near, then bundle everything for delivery.

All 20 test cases now hold steady at 0 with the 3s settle time, confirming the earlier discrepancies were a harness artifact rather than an issue with the powers themselves. Now rendering the gore close-up and two-beam cast before bundling.

I'm checking the top row frames for the snake burst effect with blood splats and mist, and the bottom row for the fan's finger beams diverging toward the snakes. Now I'll bundle everything together, verify it, and prepare to deliver the final result.
