     5→# Anchor Engine Overview
     6→
     7→Anchor is a 2D game engine for solo indie developers. It combines a C core with YueScript (a language that compiles to Lua) for game logic. The engine handles rendering, physics, audio, and input while the framework provides high-level abstractions for building games quickly.
     8→
     9→---
    10→
    11→## Core Philosophy
    12→
    13→**Locality** — Everything about a game object lives in one place. No scattered configuration files, no registering components in separate systems. A class definition contains its properties, behaviors, children, and cleanup logic together.
    14→
    15→**No bureaucracy** — No imports, no dependency injection, no boilerplate. Resources are registered once and accessed globally. Things work without setup.
    16→
    17→**YueScript** — A clean syntax that compiles to Lua. Classes, `@` for self-reference, significant whitespace, operator overloading. Pleasant to read and write.

    "text": "Perfect! Now I have a comprehensive view. Let me compile my findings into a thorough report.\n\n## COMPREHENSIVE EMOJI-BALL-BATTLES GAME ARCHITECTURE ANALYSIS\n\n### 1. MAIN GAME LOOP & FRAME STRUCTURE\n\n**Location:** `E:\\a327ex\\emoji-ball-battles\\main.yue` (3300 lines total)\n\nThe game loop is orchestrated by the Anchor framework's global `update()` function (defined in `anchor/init.yue` lines 1486-1521):\n\n- **Update Flow (144Hz physics tick):**\n  1. **Early Phase** (line 1511): `_early_update(dt)` - input handling, pre-update logic\n  2. **Main Phase** (line 1513): `_update(dt)` - game logic, movement, collisions\n  3. **Late Phase** (line 1515): `_late_update(dt)` - drawing, post-update cleanup\n  4. **Cleanup** (line 1516): Removes dead objects and finished actions\n\n**Draw Function** (lines 244-308 in main.yue):\n- Renders multiple layers in specific order: bg \u2192 back \u2192 game \u2192 front \u2192 cover \u2192 weapons \u2192 effects \u2192 ui\n- Applies shader post-processing (recolor, outline, shadow) between layer renders\n- Uses compositing and stencil masks for visual effects\n\n**Arena Class** (lines 313-1158):\n- Root container for the entire battle (extends `object`)\n- Contains: `early_update()`, `update()`, and various helper methods\n- Manages collision energy systems, plant spawning, and effects\n\n---\n\n### 2. BATTLE/ARENA INITIALIZATION\n\n**Arena Creation** (lines 313-443):\n```\nnew: =>\n  - Creates 4 walls (top, bottom/floor, left, right)\n  - Floor dimensions: arena 200x200, centered at (40, 35) on 480x270 screen\n  - Creates two balls: player_ball and enemy_ball\n  - Initializes plants container with 2-3 random plant groups\n  - Sets up cloud background using Poisson disk sampling\n```\n\n**Ball Creation** (lines 335-339):\n```\n@player_ball = ball(x:120, y:135, team:'player', weapon:'bow')\n@enemy_ball = ball(x:360, y:135, team:'enemy', weapon:'sword')\n```\n\n**Ball Class** (lines 1162-1911):\n- **Constructor** (lines 1163-1350): Initializes physics collider, weapon-specific properties, HP/UI\n- **Max HP**: 50 (line 1313)\n- **Weapons Supported**: dagger, sword, gun, bow (lines 1176-1243)\n- **Physics Setup**: Circle collider (radius 10), restitution=1, friction=0, no damping (lines 1262-1267)\n- **Weapon Hitbox**: Box shape attached to ball as non-physical sensor (lines 1268-1276)\n\n**Plant Spawning** (lines 1024-1100):\n- Spawns 2-3 random plant groups on arena floor\n- 8 predefined group configurations with specific plant arrangements\n- Validates no overlap between groups; fills gaps if needed\n- Plant types: seedling, sheaf, tulip, blossom, four_leaf_clover\n\n---\n\n### 3. RANDOMNESS & SEEDING\n\n**Global RNG Instance** (anchor/init.yue, line 87):\n```\nan\\add random!\n```\n\nThis creates a global `an.random` object accessible throughout the game. **Important: NO seed is provided in main.yue**, so it uses `os.time()` by default (unseeded).\n\n**Random Class** (anchor/random.yue, lines 26-200):\n- Constructor: `new(seed)` - creates random generator with optional seed\n- Methods: `float()`, `int()`, `angle()`, `sign()`, `bool()`, `normal()`, `choice()`, `choices()`, `weighted()`\n- `get_seed()`, `set_seed()` for deterministic control\n\n**Random Usage in Game**:\n- Cloud generation (lines 384-387): `an.random\\float()`, `an.random\\angle()`, `an.random\\int()`\n- Energy redistribution in collisions (line 571): `an.random\\normal(0.5, stddev)`\n- Collision system bypass chance (line 545): `an.random\\bool()`\n- Plant spawning (line 1033): `an.random\\int()`\n- All sound pitch variations: `an.random\\float(0.95, 1.05)`\n\n**Deterministic Replay Capability**: To implement replay, would need to seed arena's random on creation (currently not done).\n\n---\n\n### 4. VICTORY/DEFEAT CONDITION & GAME END\n\n**No explicit victory system currently exists.** Game runs indefinitely until manually stopped.\n\n**Damage System** (lines 1640-1669):\n```yue\ntake_damage: (amount, source) =>\n  return unless @parent  -- Guard against pre-init events\n  @hp -= amount\n  @spring\\pull 'hit', 0.3, 3, 0.7\n  @\\flash_ball!\n  an\\sound_play 'dagger_ball', 0.88\n  @parent\\add damage_number @x, @y - @radius - 10, amount\n  @hp_bar\\activate!\n  @hp_ui\\refresh @hp\n  @weapon_ui\\hit!\n  if @team == 'player'\n    an.camera.shake\\shake 4, 0.15\n  \n  if @hp <= 0\n    an\\sound_play 'player_death', 0.44\n    @\\kill!\n```\n\n**Line 1667**: When HP \u2264 0, death sound plays and `kill()` is called (via inherited `object` class)\n- Death triggers: damage_number popup, HP bar activation, UI refresh, weapon feedback, camera shake\n- **After death**: Object is marked for cleanup but no victory/game-over state is triggered\n\n**HP Tracking UI** (lines 1981-2064):\n- `hp_ui` class: displays heart icon with health-fill stencil mask\n- Updates on `refresh()` call (line 2031-2045)\n- Spawns particle effects on damage\n\n**Cooldown Bar UI** (lines 1947-1977):\n- Displays weapon cooldown progress below weapon icon\n- Tracks `@cooldown_bar.progress` (0-1)\n\n**No Victory Screen/Logic**: The game does not detect when a ball dies or implement any end-game state. Both balls can theoretically die without affecting gameplay.\n\n---\n\n### 5. EVENT/LOGGING SYSTEM FOR BATTLE EVENTS\n\n**Collision Events** (anchor/init.yue):\n- `an\\collision_begin_events(tag_a, tag_b)` (lines 747-779)\n- `an\\collision_end_events(tag_a, tag_b)` (lines 791-815)\n- `an\\sensor_begin_events(tag_a, tag_b)` (lines 828-852)\n- `an\\sensor_end_events(tag_a, tag_b)` (lines 864-888)\n- `an\\hit_events(tag_a, tag_b)` (lines 903-937)\n\n**Damage Event Logging** (main.yue, arena early_update):\n- **Projectile-Ball Hit** (lines 851-881): Increments `owner.hits_landed` on successful projectile hit\n- **Melee-Ball Hit** (lines 882-923): Increments `attacker.hits_landed`, may increase sword thrust damage\n- **Weapon-Weapon Collision** (lines 640-727): Triggers weapon flash, spring effects, particle spawning\n\n**Tracking Stats**:\n```yue\n@hits_landed = 0           -- incremented per successful hit (lines 868, 899)\n@arrows_per_shot = 1       -- incremented on arrow hits for bow scaling (line 873)\n@high_speed_hit_count = 0  -- tracks consecutive high-speed collisions (line 539)\n@low_horizontal_hit_count = 0 -- tracks stalling prevention (line 614)\n@system_energy = 250       -- sum of both ball speeds for energy management (line 523)\n```\n\n**No Built-in Event Log**: Events are processed each frame via collision system but not permanently logged. Events exist only as transient collision events in the `an\\collision_begin_events` query.\n\n---\n\n### 6. COLLISION ENERGY SYSTEM\n\n**Purpose**: Compensate for Box2D energy loss while maintaining gameplay pacing.\n\n**Six Subsystems** (lines 444-492 explain the design):\n\n1. **Energy Redistribution** (lines 556-596): At high speeds, redistribute energy between balls toward 50/50 split\n   - Stddev shrinks from 0.3\u21920.1 as speed increases (line 570)\n   - Blends physics result toward random distribution (line 576)\n\n2. **High Speed Bypass** (lines 536-554): Create rhythm/pacing by occasionally losing energy\n   - S-curve: 0% at 0 hits, 100% at 9+ consecutive high-speed hits (line 543-544)\n   - When triggered: energy drops to 70% (line 550), counter resets\n\n3. **Low Horizontal Velocity Prevention** (lines 611-624): Prevent stalling\n   - Triggers when combined horizontal velocity < 0.25*max_speed (line 612)\n   - Linear: 25% chance per hit, guaranteed at 4 hits (line 617)\n   - Applies random horizontal impulse (100-200) to both balls (line 621-622)\n\n4. **Wall Fallback** (lines 728-759): Probabilistic boost on ball-wall collisions\n   - Boost chance: quad_out curve from 100% (energy\u2264100) to 0% (energy\u2265600)\n   - Boost value: sine_out from 1.11x (energy\u2264250) to 1.0x (energy\u2265400)\n\n5. **Stuck Ball Detection** (lines 1489-1507): Hop impulse if sliding on floor\n   - Triggers when vertical velocity stays <5 and horizontal >5 for >0.5s\n   - Applies upward impulse + horizontal sign\n\n6. **Weapon Energy Boost** (lines 640-727): Compensate for weapon collision losses\n   - Apply 1.14x boost on weapon-weapon collisions (line 653-656)\n   - Apply weapon weight factor (heavier = slower post-collision)\n\n**Speed Cap** (lines 598-609): Max speed clamped at 448 px/s (lines 600-609)\n\n---\n\n### 7. TEST/SIMULATION INFRASTRUCTURE\n\n**Current State**: NO test or simulation infrastructure exists in the codebase.\n\n**No files matching**:\n- `*test*`, `*sim*`, `*spec*` patterns\n- No dedicated testing framework\n- No battle replay system\n- No deterministic seed system for battles\n\n**To Implement Replays**:\n1. Seed the arena's random on creation: `@\\add random(seed)`\n2. Log all player inputs/weapon selection\n3. Replay by re-running with same seed + logged inputs\n4. Currently impossible because: no input logging, RNG unseeded, no end condition\n\n---\n\n### 8.

    "text": "Good. `_update` returns immediately if `@dead` is true (line 400). And `cleanup` removes dead children. So the flow is safe:\n\n1. `a\\kill!` marks arena dead\n2. `an\\cleanup!` removes dead arena and destroys colliders\n3. Create new arena for next battle\n\nWe don't need an extra `engine_headless_step` call -- just call `an\\cleanup!` directly since it's a method on the `an` object.\n\n**Step 4.1: Timeout handling**\n\nBattles need a maximum step count to prevent infinite loops. 5 minutes at 120Hz = 36,000 steps is reasonable. If timeout occurs, record winner as the ball with more HP, or \"timeout\" if tied.\n\n**Step 4.2: Battle step function**\n\nRather than exposing the complexity to the simulation loop, wrap single-step logic:\n\n```yuescript\n-- Returns true if battle is still running\nstep_battle = (arena_obj, step_count) ->\n    engine_headless_step!\n    not arena_obj.battle_over and step_count < 36000\n```\n\n---\n\n### Phase 5: Output & Analysis\n\n**Step 5.1: CSV output**\n\nAs shown in `write_results` above, write a CSV file with one row per battle. Fields:\n- `weapon_a`, `weapon_b`, `seed`, `winner`, `steps`, `time_seconds`\n- `player_hp`, `enemy_hp` (remaining HP at end)\n- `player_hits`, `enemy_hits` (total hits landed)\n\n**Step 5.2: Summary statistics**\n\nPrint a summary to stdout during/after simulation:\n\n```\ndagger vs dagger: 52-48 (0 timeouts), avg 28.3s\ndagger vs sword: 35-65 (0 timeouts), avg 31.2s\n...\n```\n\n**Step 5.3: Detailed event log (optional)**\n\nFor deep analysis, write per-battle event logs as JSON. This is optional and could be gated behind a `--verbose` flag:\n\n```yuescript\nwrite_events = (results) ->\n    -- One JSON file per matchup\n    for matchup in *results\n        filename = \"events_#{matchup.weapon_a}_vs_#{matchup.weapon_b}.json\"\n        -- Simple JSON serialization\n```\n\nLua doesn't have built-in JSON, but we can write a simple serializer or just format the event tables as Lua tables in the output.\n\n---\n\n### Implementation Order\n\n1. **C engine: headless flag + no-ops** (Steps 1.1-1.5) -- Can test immediately with existing game code\n2. **C engine: headless step function** (Step 1.6) -- Enables Lua-driven simulation\n3. **C engine: command-line args** (Steps 1.7-1.8) -- Quality of life\n4. **Framework: headless state** (Step 2.1) -- Quick, enables game-level checks\n5. **Game: victory detection** (Step 3.1) -- Essential for simulation to work\n6. **Game: arena config (seed, weapons)** (Step 3.2) -- Essential for parameterized simulations\n7. **Game: auto-start in headless** (Step 3.4) -- Required for battles to begin\n8. **Game: event logging** (Step 3.3) -- Captures balance data\n9. **Game: cosmetic skips** (Steps 3.5-3.6) -- Performance optimization\n10. **Game: simulation runner** (Phase 4) -- Ties everything together\n11. **Output** (Phase 5) -- Results\n\nSteps 1-4 can be done and tested incrementally. Step 5 (victory detection) is the first thing that makes headless useful. Steps 6-8 add configurability. Step 9 is performance. Steps 10-11 complete the system.\n\n---\n\n### Potential Challenges & Risks\n\n**1. Physics world state between battles**: After killing all objects, the Box2D world should be clean. But if there are any lingering constraints or contacts, the next battle could behave oddly. Mitigation: verify that `physics_destroy_body` properly removes all associated shapes, contacts, and joints. Alternatively, add a `physics_reset` function that destroys and reinitializes the world.\n\n**2. RNG determinism**: The global `an.random` is shared between gameplay and cosmetic code. If headless skips cosmetic code that consumes random values, the RNG state diverges from a headed run. This is fine -- we don't need headless results to match headed results. What matters is that headless results with the same seed are identical across runs. As long as the same code path runs with the same seed, this holds.\n\n**3. Timer/action accumulation in `an`**: The `an` object has early_actions for crossfade, playlist, hit_stop_countdown. These persist across battles. Hit_stop_countdown is fine (resets when hitstop ends). Crossfade and playlist are irrelevant in headless. No issues expected.\n\n**4. Layer memory in headless**: With `commands = NULL`, no memory is wasted on command buffers. The Layer structs themselves are small. 20 layers * ~100 bytes = trivial.\n\n**5. Draw calls in update()**: The ball's `update()` method (line 1351) interleaves drawing with logic. For example, lines 1509-1551 draw the ball, and lines 1553-1620 draw the weapon. In headless, these draw calls go through the layer methods which call C functions that try to add commands -- but `layer_add_command` returns NULL (capacity 0), so the C functions return immediately. The Lua overhead is: method dispatch + C function call + capacity check + return. This is ~200ns per draw call. With ~50 draw calls per step per ball (push, image, pop, line, etc.), that's maybe 20us per step. Over 36,000 steps, that's 720ms -- noticeable but not terrible. The `an.headless` guards on visual effects (Step 3.6) avoid most particle/effect draw calls, which are the bulk.\n\n**6. Font metrics**: Some code might call `font_get_text_width` or `font_get_height` during updates. With the dummy font (height = size, no atlas), these would return approximate values. In headless, text is never visible, so this only matters if text metrics affect game logic (they don't in this codebase -- text is purely display).\n\n---\n\n### Performance Estimate\n\nWith all optimizations:\n- Physics step: ~0.2ms per step (Box2D with ~6 bodies: 2 balls, 4 walls, plus projectiles)\n- Lua update: ~0.5ms per step (all game logic, no draw overhead)\n- Total: ~0.7ms per step\n- 36,000 steps (5 min battle): ~25 seconds\n- 100 battles per matchup: ~42 minutes per matchup\n- 10 matchups * 100 battles: ~7 hours\n\nThat's slow. To speed up:\n- Remove the 120Hz constraint: step physics multiple times per `engine_headless_step` call, or make the step function take N steps\n- Use a batch step function that runs N steps in C without Lua callback overhead\n\nBetter: modify `engine_headless_step` to accept a count parameter and run N steps internally:\n\n```c\nstatic int l_engine_headless_step(lua_State* L) {\n    int count = (int)luaL_optinteger(L, 1, 1);\n    for (int n = 0; n < count; n++) {\n        // ... step logic ...\n    }\n    return 1;\n}\n```\n\nBut this won't help because the Lua update() callback is the main cost. The update function collects all objects and runs their methods. This is inherently O(objects * methods).\n\nActually, the real bottleneck might be the object system overhead. Each step, `update()` collects ALL descendants into a flat array (`an\\all!`), then iterates three times (early, main, late). With cosmetic objects skipped, the object count is: an, arena, 2 balls, 4 walls, ~0-10 projectiles, 2 cooldown_bars, 2 timers (on balls), 1 timer (on arena), 1 effects container, 1 projectiles container, springs on balls. That's ~20-30 objects. Three passes * 30 objects * 3 method calls = ~270 Lua function calls per step. This is fast -- maybe 0.1ms per step.\n\nRevised estimate: ~0.3ms per step total, or ~11 seconds per 36,000-step battle. 1,000 battles in ~3 hours. That's more reasonable, but could be improved by stepping more aggressively (e.g., fewer sub-steps in Box2D, or larger physics timestep for faster battles).\n\nActually wait -- most battles probably last 30-60 seconds (3,600-7,200 steps), not 5 minutes. So ~1-2 seconds per battle, 1000 battles in 20-30 minutes. Quite workable.\n\n---\n\n### Summary of Changes by File\n\n| File | Changes |\n|------|---------|\n| `Anchor/engine/src/anchor.c` | Add `headless_mode` flag, `engine_set_headless`, `engine_get_headless`, `engine_headless_step`. Modify `engine_init` to skip window/GL in headless. Make `texture_load`, `font_load`, `sound_load`, `shader_load_*` return dummies in headless. Make `layer_create` skip FBO allocation. Make `layer_push/pop` no-op. Make `layer_render`, `layer_clear`, `layer_draw`, `layer_draw_from`, `layer_apply_shader` return early. Skip audio init. Add `--headless` and `--script` CLI args. Skip main loop in headless. |\n| `Anchor/framework/anchor/init.yue` | Add `an.headless = engine_get_headless!` after engine_init. |\n| `emoji-ball-battles/main.yue` | Modify arena constructor to accept `{seed, player_weapon, enemy_weapon}`. Add victory detection in arena update. Add event logging. Add auto-start in headless. Skip plants, clouds, UI objects in headless (with noop stubs). Skip visual effect spawning in headless. Add `simulate()` function and headless entry point at bottom. |\n| `emoji-ball-battles/anchor/init.yue` | Same change as framework init.yue (this is a copy). |\n\n### Critical Files for Implementation\n\n- **`E:\\a327ex\\Anchor\\engine\\src\\anchor.c`** - Core engine file requiring the most changes: headless flag, dummy resource loading, no-op draw functions, headless step function, CLI args, main loop skip. All changes are gated behind `if (headless_mode)` checks, keeping existing behavior untouched.\n- **`E:\\a327ex\\emoji-ball-battles\\main.yue`** - Game code requiring victory detection, arena parameterization, event logging, cosmetic object skipping, and the simulation runner function. Most changes are in the arena class and at the file's bottom.\n- **`E:\\a327ex\\Anchor\\framework\\anchor\\init.yue`** - Framework init needs `an.headless` exposure. One-line change, but this file controls the entire init flow and must be understood for the headless path.\n- **`E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue`** - Game's copy of the framework init (same change needed here since this is what the game actually uses at runtime).\n- **`E:\\a327ex\\Anchor\\engine\\build.bat`** - Build system for the engine; no changes needed but critical for rebuilding after C changes."

User has approved your plan. You can now start coding. Start with updating your todo list if applicable

Your plan has been saved to: C:\Users\adn\.claude\plans\warm-conjuring-bumblebee.md
You can refer back to it if needed during implementation.

## Approved Plan:
# Headless Playthrough System — Implementation Plan

## Context

Emoji Ball Battles needs a way to test weapon balance by running many simulated battles without graphics, as fast as possible. Currently the game has no victory condition, no event logging, no deterministic seeding, and the engine requires a window + OpenGL context. This plan adds headless simulation capability across three layers: C engine, framework, and game code.

**Decisions made:**

- Invocation: command-line args (`--headless`, `--battles`, `--matchup`)
- Event detail: hit-level (every damage event)
- Output: HTML report + raw Lua data file

---

## Files to Modify

| File | Changes |
|------|---------|
| `Anchor/engine/src/anchor.c` | Headless flag, skip GL init, no-op layers, dummy resources, fast loop, CLI args, `engine_quit()` |
| `emoji-ball-battles/anchor/init.yue` | Expose `an.headless` + pass CLI args |
| `emoji-ball-battles/main.yue` | Victory condition, arena config, event logging, simulation runner, HTML report |
| `emoji-ball-battles/simulate.bat` | New file — convenience wrapper |

   117→
   118→### 2.1 Expose headless flag
   119→
   120→In `emoji-ball-battles/anchor/init.yue` (~line 62), after `engine_init!`:
   121→
   122→```yuescript
   123→an.headless = engine_get_headless!
   124→an.args = engine_get_args!  -- table of CLI --key=value pairs
   125→```
   126→
   127→### 2.2 Skip audio init
   128→
   129→In init.yue, gate `music_play`/`sound_play` wrappers: if `an.headless`, return immediately. (Or rely on C-level no-ops from Phase 1.4 — either works, C-level is cleaner.)
   130→
   131→---
   132→
   133→## Phase 3: Game-Level Changes
   134→
   135→All in `emoji-ball-battles/main.yue`.
   136→
   137→**Naming convention:** All headless-specific variables use `headless_` prefix (e.g., `headless_events`, `headless_step_count`). All headless guards use `-- headless:` comment prefix on the line or block. This makes headless code easy to find and distinguish from core gameplay logic.
   138→
   139→### 3.1 Victory condition
   140→
   141→In `arena` class, add battle-end detection. In `early_update` or `update`, after processing collisions:

    "text": "Perfect. Now I have a complete picture. Let me compile my findings:\n\n## Comprehensive State Leakage Analysis for Multi-Battle Headless Simulations\n\nBased on thorough analysis of the framework and game code, here's what accumulates across battles:\n\n### CRITICAL LEAK: `collider_next_id` (Yue Global Counter)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\collider.yue:19`\n\n```yuescript\ncollider_next_id = 1\n```\n\n**Problem:** This is a Lua global variable that increments every time a collider is created (line 44: `collider_next_id += 1`). It **NEVER resets** between battles.\n\n**Impact:**\n- Battle 1: collider IDs are 1, 2, 3, 4, 5...\n- Battle 2: collider IDs are 100+, 101+, 102+... (depending on battle 1 count)\n- The numeric IDs are used as keys in `an.colliders` table to map body handles to collider objects\n- While `an.colliders` itself is rebuilt fresh each battle (bodies destroyed via `b2DestroyWorld`), the ID counter causes a mismatch: old IDs in destroyed Box2D world won't match where IDs would naturally be allocated\n\n**Why it matters:** If any code walks `an.colliders` by ID or relies on consistent ID ranges across battles, this creates non-deterministic behavior and potential ID conflicts in the lookup table.\n\n---\n\n### CRITICAL LEAK: `an.colliders` (Orphaned Entry Cleanup)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue:640`\n\n```yuescript\nan.colliders = {}        -- body_handle -> collider (internal registry)\n```\n\n**Problem:** When `physics_reset()` is called:\n1. `b2DestroyWorld(physics_world)` destroys the Box2D world and all body handles\n2. A new world is created with `b2CreateWorld()`\n3. **`an.colliders` is NOT cleared** between battles in the cleanup code\n\n**Current cleanup code (main.yue:3539-3541):**\n```yuescript\nphysics_reset!\nan.collision_pairs = {}\nan.sensor_pairs = {}\nan.hit_pairs = {}\n```\n\n**Missing:** `an.colliders = {}`\n\n**Impact:** \n- Battle 1 creates colliders with IDs 1, 2, 3 and registers them in `an.colliders[1]`, `an.colliders[2]`, etc.\n- Their `destroy()` methods are called when arena is killed (object.yue:496): `child\\destroy! if child.destroy`, which removes them via `an.colliders[@id] = nil`\n- **BUT** if cleanup is incomplete (e.g., an arena object outlives physics_reset, or there's an exception), orphaned entries remain\n- More importantly: collider_next_id keeps incrementing, so battle 2's IDs (100, 101...) are never registered with the expected numeric keys\n\n---\n\n### CRITICAL LEAK: `an.colliders` Synchronization with Physics World\n\n**Root cause:** The collider ID counter and the physics world are misaligned:\n- Box2D body handles are opaque userdata; they're invalidated when `b2DestroyWorld()` is called\n- The new world has a fresh set of body handles starting from Box2D internals (likely new pointers)\n- `collider_next_id` is a linear counter that keeps incrementing globally\n\n**Scenario:** \n- Battle 1: Create 50 colliders \u2192 IDs 1-50, each body has a handle, all registered in `an.colliders`\n- Battle 2 cleanup: `physics_reset()` destroys world and all 50 body handles\n- Battle 2 creates new bodies with new handles but they're assigned IDs 51-100\n- If any code queries `an.colliders[1]` expecting a collider from battle 2, it gets the destroyed collider object from battle 1\n\n---\n\n### MAJOR LEAK: Timer State (`an.timer`)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\timer.yue:32-33`\n\n```yuescript\n@entries = {}\n@next_id = 1\n```\n\n**Instances:** `an.timer` is a global timer added to `an` at init (init.yue:88)\n\n**Problem:** \n- `@entries` stores all active timers, tweens, and watchers\n- `@next_id` generates unique IDs for anonymous timers and increments monotonically\n- While `@entries` is cleaned up frame-by-frame when timers complete, any **running timers at battle end** will leak into the next battle\n\n**Scenario:** If a timer with duration > battle lifetime is created and not explicitly cancelled, it persists:\n```yuescript\n@timer\\tween 100, @, {x: 0}  -- 100-second tween\n-- battle ends after 3 seconds\n-- tween is still in @entries with 97 seconds remaining\n-- next battle starts with the tween still updating an.x on old objects\n```\n\n**What's cleaned up:** `an\\cleanup()` marks dead objects for removal, but `an.timer` (the object) doesn't die, so `an.timer.entries` persists\n\n**What's NOT cleaned up:** \n- Any tweens targeting the old arena or its children (now dead but objects still in tweens)\n- Named timers that reference callbacks to dead objects\n- Internal state like `@next_id` (now at 50+ after battle 1)\n\n---\n\n### MAJOR LEAK: Random State (`an.random`)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\random.yue:41`\n\n```yuescript\n@rng = random_create seed or os.time!\n```\n\n**Instances:** `an.random` is a global RNG added to `an` at init (init.yue:87)\n\n**Problem:**\n- The PCG32 RNG state (@rng) is internal C state that persists\n- If battle 1 uses `an.random` without reseeding, it generates sequence A\n- Battle 2 with the same seed initializes a fresh RNG, but **only if `an.random\\set_seed()` is called**\n\n**Current behavior:** In main.yue:322, the arena sets RNG seed for **its own** determinism:\n```yuescript\nif args.seed\n  an.random\\set_seed args.seed\n```\n\n**But:** This only happens if `args.seed` is passed. If headless mode uses different seeds per battle, each new arena() call resets the global RNG.\n\n**Risk:** If code anywhere reads `an.random` before the arena constructor runs, it reads stale state.\n\n---\n\n### MAJOR LEAK: Shake/Camera State\n\n**Files:** \n- `E:\\a327ex\\emoji-ball-battles\\anchor\\camera.yue:45-56`\n- `E:\\a327ex\\emoji-ball-battles\\anchor\\shake.yue:27-42`\n\n**Camera State:**\n```yuescript\n@x = @w / 2\n@y = @h / 2\n@rotation = 0\n@zoom = 1\n@mouse = {x: 0, y: 0}\n@follow_target = nil\n@follow_lerp = 0.9\n@follow_lerp_time = 0.5\n@follow_lead = 0\n@bounds = nil\n```\n\n**Shake State:**\n```yuescript\n@trauma_instances = {}\n@trauma_amplitude = {x: 24, y: 24, rotation: 0.2, zoom: 0.2}\n@trauma_time = 0\n@handcam_enabled = false\n@handcam_amplitude = {x: 5, y: 5, rotation: 0.02, zoom: 0.02}\n@handcam_frequency = 0.5\n@handcam_time = 0\n@shake_instances = {}\n@sine_instances = {}\n@square_instances = {}\n```\n\n**Problem:**\n- Camera and Shake are children of `an` (added globally)\n- They persist across battles\n- **At battle end, `@follow_target` still points to the dead arena's player_ball**\n- **`@trauma_instances`, `@shake_instances` arrays may contain active effects not yet expired**\n- **`@handcam_time` and `@trauma_time` keep accumulating** even between battles\n\n**Current cleanup:** None. The game doesn't reset camera/shake state between headless battles.\n\n**Impact on visual mode:** Probably fine (camera just follows nothing, shake decays).\n**Impact on determinism:** Shake state leaks \u2192 different visual output between runs.\n\n---\n\n### MODERATE LEAK: Playlist State (`an.playlist*`)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue:385-392`\n\n```yuescript\nan.playlist = {}           -- array of track names\nan.playlist_index = 1      -- current index\nan.playlist_shuffled = {}  -- shuffled order (when shuffle enabled)\nan.playlist_shuffle_enabled = false\nan.playlist_crossfade_duration = 0\nan.playlist_channel = 0\nan.playlist_just_advanced = false\n```\n\n**Problem:**\n- If music is playing when a battle ends, `playlist_index` and `playlist_shuffled` persist\n- `an.music_stop()` (init.yue:318) resets `@playlist_channel = 0` only when stopping all channels\n\n**Risk:** Low in headless mode (no audio), but `playlist_index` could be stale when next battle starts.\n\n---\n\n### MODERATE LEAK: Hitstop State (`an.hit_stop_*`)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue:98-102, 591-610`\n\n```yuescript\nan.hit_stop_active = false\nan.hit_stop_excluded_tags = {}\nan.hit_stop_remaining = 0\nan.pre_hitstop_time_scale = 1.0  -- (set during hitstop)\n```\n\n**Cleanup (main.yue:3543-3545):**\n```yuescript\nan.hit_stop_active = false\nan.hit_stop_remaining = 0\nan.hit_stop_excluded_tags = {}\n```\n\n**Status:** PROPERLY CLEANED UP between battles. Good.\n\n---\n\n### MODERATE LEAK: Time Scale State (`an.time_scale`)\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue:99`\n\n```yuescript\nan.time_scale = 1.0\n```\n\n**Cleanup (main.yue:3542):**\n```yuescript\nan.time_scale = 1.0\n```\n\n**Status:** PROPERLY CLEANED UP between battles.\n\n---\n\n### MODERATE LEAK: Collision Pair Registrations\n\n**File:** `E:\\a327ex\\emoji-ball-battles\\anchor\\init.yue:640-642`\n\n```yuescript\nan.collision_pairs = {}  -- tracks enabled pairs for queries\nan.sensor_pairs = {}\nan.hit_pairs = {}\n```\n\n**Cleanup (main.yue:3539-3541):**\n```yuescript\nan.collision_pairs = {}\nan.sensor_pairs = {}\nan.hit_pairs = {}\n```\n\n**Status:** PROPERLY CLEANED UP between battles. These are just metadata tables listing which tag pairs have collisions enabled; they're cleared and re-registered in `physics_setup()`.\n\n---\n\n### MINOR LEAK: Layer Transform Stack\n\n**Potential issue:** Layers store a stack of transforms via `layer\\push()` and `layer\\pop()`. Between battles, if a pop is missed, the stack isn't cleared. However, the camera attachment/detachment logic in update() (init.yue:1500-1502, 1521-1523) should keep this balanced.\n\n**Status:** Unlikely to leak in practice, but no explicit reset.\n\n---\n\n### C-SIDE GLOBALS That Persist\n\n**File:** `E:\\a327ex\\Anchor\\engine\\src\\anchor.c`\n\nThese globals survive `physics_reset()`:\n\n1. **`global_rng`** (line 577): The PCG32 RNG state for `random_*` C functions\n   - Persists across world resets\n   - Only reset if Lua explicitly calls `random_seed()`\n   \n2. **`music_channels[2]`** (line 1384): Music playback state\n   - Audio buffers and volume persist\n   - Not reset by `physics_reset()`\n   - Only affects audio playback, not physics/game state\n\n3. **Input state arrays** (lines 2271-2288): Keyboard, mouse, gamepad states\n   - Persists across world resets\n   - No impact on determinism (input is per-frame)\n\n4. **`physics_world`, `physics_initialized`** (lines 444-445): **PROPERLY RESET** by `physics_reset()`\n\n---\n\n## Summary Table\n\n| State | Location | Accumulates? | Cleaned Between Battles? | Impact |\n|-------|----------|--------------|--------------------------|--------|\n| `collider_next_id` | collider.yue:19 | YES (global counter) | NO | **CRITICAL**: ID misalignment between worlds |\n| `an.colliders` table | init.yue:640 | NO (entries removed) | **INCOMPLETE**: not explicitly cleared | **CRITICAL**: orphaned entries if cleanup fails |\n| `an.timer.entries` | timer.yue:32 | PARTIALLY (auto-removes on completion) | NO | **CRITICAL**: long-duration tweens leak |\n| `an.timer.next_id` | timer.yue:33 | YES | NO | MAJOR: counter starts at 50+ in battle 2 |\n| `an.random.rng` | random.yue:41 | NO (reset via `set_seed()`) | YES (arena ctor) | MINOR: works if seeded each battle |\n| Camera position/state | camera.yue:45-56 | PARTIALLY (`@follow_target` stale) | NO | MAJOR: stale references |\n| Shake instances | shake.yue:29-42 | PARTIALLY (expire naturally) | NO | MAJOR: `@trauma_time`, `@handcam_time` accumulate |\n| `an.time_scale` | init.yue:99 | NO | YES | CLEAN: properly reset |\n| `an.hit_stop_*` | init.yue:98-102 | NO | YES | CLEAN: properly reset |\n| Collision/sensor/hit pairs | init.yue:640-642 | NO | YES | CLEAN: properly reset |\n\n---\n\n## Recommendations\n\nTo fix leaks for deterministic multi-battle runs:\n\n1. **Reset `collider_next_id`** between battles:\n   ```yuescript\n   collider_next_id = 1  -- in the cleanup section\n   ```\n\n2. **Explicitly clear `an.colliders`**:\n   ```yuescript\n   an.colliders = {}  -- in main.yue:3539+\n   ```\n\n3. **Clear timer state completely**:\n   ```yuescript\n   an.timer.entries = {}\n   an.timer.next_id = 1\n   ```\n\n4. **Reset camera state**:\n   ```yuescript\n   an.camera.x = an.camera.w / 2\n   an.camera.y = an.camera.h / 2\n   an.camera.rotation = 0\n   an.camera.zoom = 1\n   an.camera.follow_target = nil\n   an.camera.bounds = nil\n   ```\n\n5. **Clear all shake instances**:\n   ```yuescript\n   an.camera.shake.trauma_instances = {}\n   an.camera.shake.shake_instances = {}\n   an.camera.shake.sine_instances = {}\n   an.camera.shake.square_instances = {}\n   an.camera.shake.trauma_time = 0\n   an.camera.shake.handcam_time = 0\n   ```\n\nAll of these should be added to the cleanup block in `main.yue:3536-3546` after `physics_reset()` is called."

Entered plan mode. You should now focus on exploring the codebase and designing an implementation approach.

In plan mode, you should:

1. Thoroughly explore the codebase to understand existing patterns
2. Identify similar features and architectural approaches
3. Consider multiple approaches and their trade-offs
4. Use AskUserQuestion if you need to clarify the approach
5. Design a concrete implementation strategy
6. When ready, use ExitPlanMode to present your plan for approval

Remember: DO NOT write or edit any files yet. This is a read-only exploration and planning phase.

     5→Emoji Ball Battles needs a way to test weapon balance by running many simulated battles without graphics, as fast as possible. Currently the game has no victory condition, no event logging, no deterministic seeding, and the engine requires a window + OpenGL context. This plan adds headless simulation capability across three layers: C engine, framework, and game code.

The file C:\Users\adn\.claude\plans\warm-conjuring-bumblebee.md has been updated. Here's the result of running `cat -n` on a snippet of the edited file:

User has approved your plan. You can now start coding. Start with updating your todo list if applicable

Your plan has been saved to: C:\Users\adn\.claude\plans\warm-conjuring-bumblebee.md
You can refer back to it if needed during implementation.

## Approved Plan:
# Balance Report System — Implementation Plan

## Context

The headless simulation system is working: each battle runs as a separate process, results are deterministic and match visual runs. Now we need a comprehensive balance report that runs every weapon against every other weapon and generates a single unified HTML report.

**Weapons:** `dagger`, `sword`, `bow`, `gun` (4 weapons)
**Matchups:** 10 unique pairs (4 mirrors + 6 non-mirrors)
**Initial test:** 5 battles per matchup = 50 battles total
