062026 11

Opus 4.8

Summary

Session 11 of 062026 (working-title build-heavy action roguelite on the snkrx-template / Anchor 2 stack) was a codebase + design review rather than feature work — the first run of a trial "review every ~10 sessions" cadence the owner wants to evaluate. No stat system, modifiers, or new units were built. The session read the whole game layer to ground a mental model, then stress-tested the ability architecture by imagining real modifiers and reasoning through exactly where each would hook in and where it would fight the current design. Ended as NDA-sealed log "062026 11". (Note: the session was first assumed to be "062026 10", but the seal flow discovered an undocumented prior session already sealed as "062026 10" on 2026-06-22 — the Barrage-redesign/swap/shield-passive session that memory had skipped — so this is correctly 062026 11. The memory drift was itself caught by the review.)

Review method (owner-defined):

  • The owner refined the approach: rather than an abstract audit, "imagine modifiers and then you tell me how they would be implemented, in terms of where each thing would go, I correct any architectural mistakes, you codify those corrections so next instances don't make the same mistakes."
  • Probes drawn from real PoE / SNKRX / design.md modifiers, deliberately spread across stress axes (structural / conditional / keystone-transform), each given a fit verdict: fits clean / needs a seam / fights the architecture.
  • Grounding read precedes the probes (read the whole game layer, verify against code because memory drifts).
  • Recorded as the feedback_codebase_review_cadence memory (a trial, not yet a confirmed rule). Owner: "I'm at least going to try to see if it helps in the future."

Grounding read — game-layer summary produced (skipped the Anchor framework + the generic snkrx toolkit):

  • main.lua (~1012 lines) — orchestrator + tunable store (all ability tunables are globals so the F1 tuner edits by _G[key]); physics matrix; the four GENERIC ability binds (primary/secondary/mobility/ultimate) each character reinterprets; spawn_wave / auto_spawn_update debug enemy supply; the update/draw skeleton + 3 collision handlers (player↔enemy pl:hit+e:push, enemy↔wall e:wall_bump, projectile↔enemy pr:on_hit).
  • snkrx/player.lua (~1274 lines) — both kits, the damage model, and the stat/buff/shield wiring. update_abilities() is the if self.character == 'swordsman' … elseif 'archer' dispatch. ability_damage(name) = base D × per-ability coeff, the single damage source for gameplay AND cards. Swordsman: cleave / start_leap_slam (+update_leap_slam/leap_land) / surge / start_blade_dance (+update_blade_dance/blade_dance_pick_target/blade_dance_start_hop/blade_dance_land). Archer: archer_shoot / cone_shot / nova_tumble (+update_tumble) / barrage, all routed through archer_cast (+echo_tick) for the Echo passive.
  • cone.lua (Archer Cone Shot blast), hud.lua + card.lua (game UI: RoR2 split-corner HUD + per-ability hover cards + glossary), snkrx/buff.lua (timed buffs riding stats), snkrx/shield.lua (shared shield pool), snkrx/seeker.lua (the only enemy), snkrx/stats.lua (the stat machinery — the stat-scaling seam).
  • Drift found: flurry.lua is loaded by init + ticked every frame in main.lua, but spawn_flurry is ONLY called from parked/cross_guard.lua → dead-but-wired (the flurrys[] list is always empty in the live build; kept for the parked Cross Guard).

Code + doc changes made:

  • Renamed bd_* → blade_dance_* across player.lua (all Blade Dance bezier/state fields + methods: blade_dance_hop_t, blade_dance_pick_target, blade_dance_p0x…, blade_dance_hit_set, etc.) and one stale comment in main.lua. Owner rule: "don't use abbreviations for ability/modifier names."
  • Added a "No abbreviations in ability / modifier names" rule to 062026/.claude/CLAUDE.md (Working style section) so next instances comply.
  • Fixed a stale passage in CLAUDE.md's "Character-branched abilities" section (it described the parked Lunge start_dash/update_dash; rewritten to the live Swordsman + Archer kits).

Prior art studied — the Invoker/Orblike "plan-tree" (Invoker-old/plan.lua):

  • A "plan" is a tree of plain tables: LEAF nodes (leaf_projectile / leaf_area) carrying their own params + continuation pointers (on_expire, planned on_hit/on_tick) that hold sub-plans; BRANCH nodes (branch_echo / branch_barrage = count+delay+child) that emit a child N times. plan_walk = DFS over child + on_expire (modifier targeting); plan_execute = the recursive executor (leaves schedule a spawn, branches recurse, continuations fire on the spawned entity's event).
  • Modifiers were DESIGNED to be pure tree-transforms (walk + tag-match + wrap nodes) but never implemented — the modifier-application step is a TODO at Invoker-old/cast.lua:194; only Fireball (abilities/fireball.lua) was built; the project reset to snkrx-template before the modifier layer landed.
  • Confirmed NOT present in snkrx-template / 062026 (foundational decision #1: "visual generalization only, NO modifier system"; abilities are flat if character == methods). A subagent (Explore) over-claimed the modifiers were implemented; corrected by reading the primary source.

Assessment of the plan-tree: good at a narrow, powerful job (composing delivery/emission — structural multipliers like echo/barrage, and effect chaining via continuations), but the WRONG overall fit for 062026 because most of its abilities are player-driven state machines (Leap Slam, Blade Dance, Nova Tumble, Surge), not emission graphs — the tree literally can't represent them. The build depth the game wants also lives in triggers/conditions/state, which the tree barely touches. The thing worth stealing is the tag + hook + uniform-targeting idea WITHOUT abilities-as-data.

Probe 1 — Echo as a per-ability general modifier (applies to [active] abilities):

  • The [active] tag filter is a NO-OP — every current ability is [active]; the real classifier is mechanical SHAPE, which no current tag encodes.
  • "Fire again" FRACTURES by ability shape: emitters (Cleave/Shoot/Cone) = Replay (plain re-call, fits clean); player-state-machines (Leap/Blade/Tumble) = Chain-on-complete (can't overlap themselves); charge-ult / self-buff (Barrage/Surge) = Amplify (Barrage doubles its count; Surge naive-refresh is ~inert, could stack). The existing Archer Echo already needed 3 different strategies (archer_cast plain re-call, barrage echo_tick doubling, tumble_echo_pending chain-on-landing).
  • Implied seam: a uniform player:cast(name) chokepoint (generalize archer_cast to both characters), per-ability modifier state, and a per-ability declared replay-shape (the completion points already exist: leap_land, tumble landing, blade final hop).

Probe 2 — Wildcard (press = cast a random OTHER ability in the kit):

  • New axis: invoke an arbitrary ability by reference. Needs (a) an enumerable ability roster (none exists — the kit is implicit in the dispatch + hud_slots arrays), (b) uniform invocation by name (entry points differ: cleave / start_leap_slam / surge / start_blade_dance / archer_shoot…), (c) effect/gating separation — cast the rolled ability for free, skipping its cd/charge cost (the echo flag is a partial, inconsistent prototype).
  • Targeting mostly Just Works because abilities read live globals (mouse/aim), not passed args — a point FOR the flat design.
  • If invocation routes through the chokepoint, the callee's own modifiers compose for free (Wildcard → cast('leap') → Leap's Echo fires).
  • The tree could only randomly cast the emitter abilities (can't represent the state machines), so flat+chokepoint is strictly MORE capable here.

Converged spine (both probes, independently): a single player:cast(name, opts) chokepoint; abilities as an enumerable name-keyed roster (= "abilities as addressable handles": name → {invoke, tags, replay-shape, cost} — the useful 80% of the plan-tree WITHOUT making abilities data); gating (cd/charge check AND stamp) moved out of ability methods into cast() so methods become pure effect; a per-ability replay-shape; and opts.free. Recommended over BOTH the plan-tree and the current pure-flat code.

Further stress axes mapped (PoE 1/2 + SNKRX, NOT probed — what the eventual modifier system must handle), ordered by architectural impact:

  1. Carrier-behavior mutation (GMP +projectiles / chain / fork / return / pierce) — COLLIDES with template foundational decision #1 "no carrier mods," is the plan-tree's home turf, and is the ONE axis where flat is weakest = the genuine open decision.
  2. Event/trigger bus (Cast-on-Crit, Cast-when-Damage-Taken, on-kill explode) — DOESN'T EXIST; seeker:hit/seeker:die/player:hit are FX-only sinks.
  3. Damage-as-pipeline + enemy debuff state (Shock/Ignite/conversion/"more") — D×coeff + stats.lua's added/increased are insufficient; enemies need debuff state the damage step reads.
  4. Inter-ability combos (PoE2 primer/detonator) — abilities are independent islands today.
  5. Ability-origin decoupling (Mirage Archer / Spell Totem) — cast needs a caster/origin param, not bound to p.
  6. Modifiers-that-grant-modifiers (Headhunter) — the meta deep end; needs modifiers as runtime add/removable with their own lifecycle.
  7. Conditional/stateful gems (Berserk <50% HP, Adrenaline while ≥3 near) were the queued-but-unprobed representative case — they need the per-run state layer (stats/buff is the seed).

Wrap-up: Owner satisfied — "the codebase is simple and clean enough so far… I'm confident next instances will do a good job." Memory updated: project_062026.md gained a Session 11 block (tagging this sealed log as the modifier/ability design-exploration reference) PLUS a backfilled Session 10 entry for the previously-undocumented 2026-06-22 session; MEMORY.md index updated; new feedback_codebase_review_cadence memory created. Session sealed as NDA "062026 11".
