Subject: [PATCH 01/39] feat: harden map validation with bounds checking and
 playability gate

- Add grid size bounds (5-30), tile dimension checks, terrain type validation,
  spawn/exit coordinate and count validation to validateMapJson
- Add validateMapPlayability method for pre-game checks (spawn/exit presence,
  no overlap, dimensions)
- Add pre-game validation in map-select before navigating to /play
- Add defensive checks in map-bridge convertToGameBoard (null guard, gridSize
  clamping, tiles validation)
- 33 new tests covering all validation edge cases (1689 total, all passing)

Subject: [PATCH 04/39] refactor: extract GameSetupComponent and
 TowerInfoPanelComponent from game-board
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move setup panel (difficulty, modifiers, endless mode) and tower info panel
(stats, upgrade/sell, specialization, targeting) into standalone child
components. Parent retains all business logic; children only emit events.

1730 tests passing (was 1656 — +20 new component tests, +54 from prior step).

Subject: [PATCH 05/39] feat: add WebGL init resilience to editor component

Mirror the game-board error handling pattern: try/catch around
ngAfterViewInit init chain, WebGL detection before renderer creation,
animate() guard against null renderer, ngOnDestroy guards for partial
init, and error overlay UI with fallback navigation.

Subject: [PATCH 06/39] refactor: extract TowerSelectionBarComponent and
 GameControlsComponent; cache tower costs

Move tower selection bar (buttons, tooltips, affordability) and game
controls (wave start, pause, speed, range/path toggles) into standalone
child components with their own templates, SCSS, and specs. Pre-compute
effective tower costs into a Map to eliminate template function calls.

Subject: [PATCH 08/39] fix: deduplicate interaction handlers, cache raycasting
 arrays, fix range rings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Extract handleInteraction() — eliminates 56 lines of duplicated click/tap logic
- Extract recordGameEndIfNeeded() — consolidates duplicated game-end recording
- Cache tileMeshArray and towerChildrenArray for raycasting performance
- Refresh range rings after tower upgrade when showAllRanges is active
- Add spawn retry safety net (SPAWN_MAX_RETRIES=300) in wave.service

Subject: [PATCH 09/39] fix: harden localStorage error handling, clean unused
 CSS properties

- Map storage: explicit QuotaExceededError detection with warning logs
- Settings service: log warnings on save failures instead of silent swallow
- Player profile: pre-computed unlockedSet avoids Set allocation per getProfile()
- Remove 18 unused CSS custom properties (verified grep-clean)

Subject: [PATCH 10/39] fix: scope editor services to EditorModule instead of
 root

- EditHistoryService, CameraControlService, EditorStateService: @Injectable()
- Added all three to EditorModule providers array
- Updated spec files to provide services explicitly in TestBed
- Services now destroyed on route away from /edit (no stale state)

Subject: [PATCH 12/39] feat: loading spinner during Three.js initialization

- Game and editor show spinner overlay while renderer initializes
- Spinner hidden on success or error (error fallback takes over)
- Respects prefers-reduced-motion (animation disabled)
- 2 new tests for isLoading state

Subject: [PATCH 14/39] =?UTF-8?q?perf:=20mobile=20GPU=20optimizations=20?=
 =?UTF-8?q?=E2=80=94=20cap=20pixel=20ratio,=20shadows,=20particles,=20bloo?=
 =?UTF-8?q?m?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Cap devicePixelRatio to 1.5 on mobile (prevents 9x overdraw on 3x screens)
- Cap shadow map to 1024px on mobile (from 2048)
- Halve particle count on mobile
- Skip bloom pass on phones (≤480px) — expensive GPU effect
- Centralized MOBILE_CONFIG constants
- Same optimizations applied to editor renderer

- Wave service: endless generation scaling, getMaxWaves, spawn retry skip, reward formula (11 tests)
- Tower combat: targeting strategies (nearest/first/strongest), cycle wrap, chain dedup (8 tests)
- Enemy service: shield absorption edge cases, MIN_ENEMY_SPEED floor, SPEED_DEMONS selective, flying SLOW immunity (13 tests → trimmed to fit)

+## Red Team Critique — feat/hardening-iv (2026-03-07)
+
+### Finding 1: Silent Enemy Skip on Spawn Retry Limit (HIGH — FIXED)
+**Location:** `wave.service.ts:154`
+**Risk:** When enemy spawn fails 300 consecutive times, the enemy is silently discarded. If a map becomes unplayable mid-wave, enemies vanish from the queue without any signal to the player or logs for debugging.
+**Fix:** Added `console.warn` when skipping an enemy after max retries.
+
+### Finding 2: Misplaced JSDoc Comment (LOW — FIXED)
+**Location:** `game-board.component.ts:194-195`
+**Risk:** `recordGameEndIfNeeded()` JSDoc was orphaned above `rebuildTowerChildrenCache()`. Misleading for maintainers.
+**Fix:** Moved JSDoc to the correct method.
+
+### Finding 3: Misleading Template Comment (LOW — FIXED)
+**Location:** `game-board.component.html:53`
+**Risk:** Comment said "shown during SETUP and INTERMISSION" but template only shows during INTERMISSION. Intentional design (wave preview makes no sense before game starts) but comment contradicts behavior.
+**Fix:** Updated comment to match actual behavior.
+
+### Verified NOT bugs:
+- ReadonlySet<string> for unlockedSet: correct TS pattern (prevents external mutation, internal reassignment is fine)
+- BFS on mousemove: preview cache key gates the check — BFS only runs on tile change, not every move
+- Mobile shadow cap + 3-point lighting: correctly applied to keyLight after merge resolution
+- Raycasting cache invalidation: tileMeshArray rebuilt in renderGameBoard, towerChildrenArray rebuilt after place/sell
+
+## Deployment Checklist — feat/hardening-iv

Subject: [PATCH 18/39] fix: extract visual-overhaul magic numbers into
 constants
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add SKYBOX_CONFIG.timeScale for ms→seconds conversion (replaces `* 0.001`)
- Add sinNormalized() utility for [-1,1]→[0,1] mapping (replaces `* 0.5 + 0.5`)
- Document GLSL shader magic numbers inline per CLAUDE.md convention

- saveMap() returns null on storage failure; callers show appropriate alerts
- File import rejects files > 10 MB (prevents browser tab crash)
- Achievements array capped to defined count on localStorage load
- testCanvas WebGL context released after feature detection (both components)
- migrateOldFormat() preserves source data when save fails
- importMapFromJson() simplified with null-propagation from saveMap()
- +4 tests: save failure/success alerts, file size limit, achievements cap

Red team pass 2 + 3: 5 findings, all fixed. STRATEGIC_AUDIT.md updated.

+## Red Team Critique — feat/hardening-iv Pass 2 (2026-03-08)
+
+### Finding 1: saveMap() silently returns success on quota failure (MEDIUM)
+**Location:** `map-storage.service.ts:62-71`
+**Risk:** When localStorage quota is exceeded, `saveMap()` catches the error, logs a warning, but still returns a mapId and updates the metadata index. The caller (editor auto-save, manual save) sees a valid mapId and believes the save succeeded. The metadata entry points to a non-existent map — next load fails silently. The `importMap()` path was patched with verify-after-write (line 280), but direct saves were not.
+**Fix:** Return `null` on save failure so callers can detect and handle the error (e.g., show a toast).
+
+### Finding 2: testCanvas WebGL context not released (LOW)
+**Location:** `game-board.component.ts:813-814`, `novarise.component.ts:245-246`
+**Risk:** Both `initializeRenderer()` methods create a temporary canvas + WebGL context for feature detection but never release the context. The canvas is a local variable (eligible for GC) but the WebGL context may persist until GC runs, consuming one of the browser's limited WebGL context slots (typically 8-16).
+**Fix:** Call `WEBGL_lose_context` extension after the check to explicitly release the context.
+
+### Finding 3: Visual-overhaul magic numbers extracted (LOW — FIXED in prior commit)
+**Location:** `game-board.component.ts:1595,1778,1801,1824,1834,1836`
+**Risk:** Three `time * 0.001` patterns and three `* 0.5 + 0.5` patterns were bare numeric operations without named constants. Already fixed in commit 83c69c4 via `SKYBOX_CONFIG.timeScale` and `sinNormalized()`.
+
+### Verified NOT bugs:
+- Trail disposal: `removeProjectileMesh()` properly disposes trail geometry + material; `cleanup()` calls it for all active projectiles
+- Impact flash disposal: shared geometry disposed in `cleanup()`, per-flash materials disposed on expiry
+- Chain arc zigzag `Math.random()`: non-deterministic but purely visual — does not affect game state or fixed timestep determinism
+- Particle service: all new numeric literals (`emissiveIntensity`, `roughness`, `metalness`, `sizeVariation`, `scaleEnd`) sourced from `DEATH_BURST_CONFIG`
+- Child components: all 6 are pure presentational (inputs + EventEmitters), no subscriptions to leak
+- `updateStatusVisuals()` `return` in forEach: correctly exits callback for current enemy, does not skip reset for other enemies
+
+---
+
+## Red Team Critique — feat/hardening-iv Pass 3 (2026-03-08)
+
+### Finding 1: File import has no size limit (MEDIUM — FIXED)
+**Location:** `map-storage.service.ts:promptFileImport()`
+**Risk:** `file.text()` loads entire file into memory with no size check. A user accidentally selecting a multi-GB file crashes the browser tab.
+**Fix:** Added `MAX_IMPORT_FILE_SIZE` (10 MB) check before `file.text()`.
+
+### Finding 2: Achievements array unbounded on localStorage load (LOW — FIXED)
+**Location:** `player-profile.service.ts:load()`
+**Risk:** Parsed `achievements` array from localStorage is spread without length validation. Crafted data could contain thousands of entries.
+**Fix:** `parsed.achievements.slice(0, ACHIEVEMENTS.length)` caps to defined achievement count.
+
+### Verified NOT bugs (Pass 3):
+- Material casts (`as THREE.MeshStandardMaterial`) in animation loops: materials structurally guaranteed by creation code in GameBoardService — no code path creates mesh without MeshStandardMaterial
+- `getEditorMapState()!` in restartGame: guarded by `hasEditorMap()` check on line before
+- Spatial grid rebuild: correctly called after tower place/remove
+- `startWave()` double-call: guarded by phase check in GameStateService
+- restartGame() state reset: covers all fields including new ones from this branch
+- `totalInvested` tracking: uses actual modifier-adjusted cost, not base config cost

Subject: [PATCH 22/39] fix: raycasting breaks after zoom, minimap overlaps
 tower bar on mobile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add camera.updateMatrixWorld() before all raycaster.setFromCamera() calls
  in both game and editor — OrbitControls.update() changes camera position
  without refreshing matrixWorld, causing stale rays after zoom
- Disable left-click orbit (reserved for tower placement), move orbit to
  right-click; WASD still pans, scroll still zooms
- Shrink minimap from 150px to 80px on phones (≤480px) and reposition from
  bottom-left to top-left to avoid overlapping the tower selection bar
- Derive minimap mobileBreakpoint from MOBILE_CONFIG.phoneBreakpoint
  (single source of truth)
- Add MOUSE_ACTION_DISABLED constant to camera.constants.ts

+**Risk:** `mobileBreakpoint: 480` duplicates `MOBILE_CONFIG.phoneBreakpoint` from `mobile.constants.ts`. If the phone breakpoint is ever changed, the minimap won't follow — two sources of truth for the same threshold.
+**Fix:** Import and reference `MOBILE_CONFIG.phoneBreakpoint` instead of hardcoding `480`.
+
+### Finding 2: OrbitControls mouseButtons.LEFT = -1 type cast (LOW)
+**Location:** `game-board.component.ts:1088`
+**Risk:** `-1 as THREE.MOUSE` lies to the type system. The runtime behavior is correct (OrbitControls' switch falls to `default: state = NONE`), but a future Three.js update could change how unknown values are handled. The cast is fragile.
+**Fix:** Use a named constant (`MOUSE_DISABLED = -1 as THREE.MOUSE`) in camera.constants.ts so the intent is documented and the cast is centralized.
+
+### Finding 3: Minimap size/position not responsive to orientation change (LOW)
+**Location:** `minimap.service.ts:36`
+**Risk:** `isMobile` is evaluated once at `init()` time. Device rotation (portrait→landscape) won't trigger recalculation. The minimap stays small and top-left even when landscape has room for the full desktop layout.
+**Fix:** Not critical — restartGame() re-inits the minimap which picks up the new orientation. True fix would require a resize listener in the service, which is overengineering for this scope.
+
+### Verified NOT bugs:
+- `updateMatrixWorld()` in editor touchstart/touchmove: defensive but harmless since editor disables orbit/pan on OrbitControls. No runtime cost concern (single matrix multiply per event).
+- `updateMatrixWorld()` frequency in mousemove handler: negligible cost vs. the renderer's own per-frame matrix updates.

Subject: [PATCH 25/39] fix: minimap mobile detection uses container width, not
 window

window.innerWidth doesn't reflect the actual layout width when using
DevTools device simulation or when the game is embedded in a narrower
container. Use container.clientWidth instead for reliable mobile
detection at minimap init time.

Subject: [PATCH 26/39] fix: use matchMedia for minimap mobile detection

window.innerWidth and container.clientWidth both fail to reflect the
CSS viewport in DevTools device simulation. matchMedia queries the same
viewport that CSS media queries use, so it works reliably everywhere.

Subject: [PATCH 27/39] fix: minimap mobile positioning via CSS media queries
 instead of JS detection

JS-based viewport detection (window.innerWidth, clientWidth, matchMedia)
failed to reliably detect mobile in DevTools responsive mode and on
deployed previews. Moved all minimap positioning to CSS class
(.minimap-canvas in styles.css) with @media (max-width: 480px) query.
Desktop: bottom-left 150px. Mobile: top-left 80px.

Subject: [PATCH 29/39] fix: hide FPS counter and help button on mobile to
 declutter top-right
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

FPS counter and keyboard shortcut help (?) are not useful on phones.
Hiding them at ≤480px so the audio toggle has room and doesn't crowd
into the HUD bar.

Tower selection on mobile (≤480px) now renders as a narrow column on the
left side below the minimap (icon + cost only, no name/hotkey/tooltip).
This frees the entire bottom of the screen that the 3×2 grid was eating.
Speed controls move to bottom-right with no offset needed.

Sprint 1: Add GameBoardTile spec (41 tests) — factory methods, edge cases
Sprint 2: Add three-utils spec (11 tests) — disposeMaterial with all input types
Sprint 3: Fix stale enemy leak reference — updateEnemies() now returns
LeakedEnemyInfo { id, leakDamage } instead of bare IDs, eliminating
fragile post-lookup pattern

1898 → 1950 tests, all passing.

Sprint 4: Explicit statusEffectService.removeAllEffects() on enemy kill/leak
  before removeEnemy(), preventing stale effect entries (+4 tests)
Sprint 5: Reset minimap visible flag in cleanup() to prevent state leak
  across restart cycles (+3 tests)
Sprint 6: Extract 4 magic numbers from game-board.component.ts into
  GAME_TIMING_CONFIG, TOWER_VISUAL_CONFIG, ENEMY_VISUAL_CONFIG

1950 → 1957 tests, all passing.

Sprint 7: WebGL context loss recovery — shows overlay on GPU context
  loss, auto-resumes on restoration, guards animate loop (+2 tests)
Sprint 8: Restart state consistency integration tests — 20 tests
  verifying all services reset to initial state after restartGame()
Sprint 9: Keyboard shortcut test coverage — M/m (minimap), H/h (help),
  V/v (path), Space, plus VICTORY/DEFEAT blocking for all keys (+18 tests)
Sprint 10: Mobile touch hardening — multi-touch guard prevents tower
  placement during pinch-to-zoom, phase guard in handleInteraction
  blocks raycasting during VICTORY/DEFEAT (+7 tests)

1957 → 2005 tests, all passing.

Sprint 11: Guard WebGL context restore — check renderer.getContext()
  before resuming animate loop after context restoration
Sprint 12: Verified tower cache rebuild — no fix needed, cache already
  rebuilt on add/remove, upgrades only modify existing mesh properties
Sprint 13: Fix tower cost desync — tryPlaceTower() now uses
  getEffectiveTowerCost() instead of inline calculation
Sprint 14: Wave preview overflow-x: hidden, recordGameEnd idempotence
  test, contextLost flag test (+2 tests)

2005 → 2007 tests, all passing.

Sprint 15: Dedicated context-lost-overlay CSS class with shared SCSS
  placeholder — separates recoverable vs init error overlay semantics
Sprint 16: Minimap init() guard — auto-cleanup if canvas exists,
  prevents orphaned canvases on double-init (+1 test)
Sprint 17: Editor mobile audit — no changes needed, already has proper
  touch targets (44px), bottom sheet, and 768px breakpoints
Sprint 18: Skybox shader magic numbers fully documented inline,
  5 enemy service edge case tests (remove nonexistent, empty map,
  no spawn points, damage dead enemy, no exit points)

2007 → 2013 tests, all passing.

Sprint 19: Map storage resilience — guard loadMap against missing data
  field, guard getAllMaps against non-array parsed result (+2 tests)
Sprint 20: GameStateService edge case tests — 13 new tests covering
  setPhase idempotency, startWave DEFEAT guard, loseLife(0), exhaustive
  reset verification, endless highestWave tracking, rapid startWave
  double-call guard, reward accumulation, defensive copies (+13 tests)

2013 → 2028 tests, all passing.

+## Red Team Critique — 2026-03-08 (Hardening IV Final Gate)
+
+### Finding 1: Dead MINIMAP_CONFIG mobile constants (MEDIUM)
+**Location:** `constants/minimap.constants.ts:5-9`
+**Risk:** `mobileCanvasSize`, `mobileBreakpoint`, `mobilePaddingTop`, `mobilePaddingLeft` are defined but never consumed. CSS media queries in `styles.css` now handle mobile sizing. Dead config implies mobile minimap is JS-driven when it isn't — misleads future devs.
+**Fix:** Remove dead constants. CSS is the single source of truth for mobile minimap layout.
+
+### Finding 2: Dead MINI_SWARM_MESH_SEGMENTS import (LOW)
+**Location:** `services/enemy.service.ts:3`
+**Risk:** Imported from `enemy.model.ts` but never referenced in the service body. Suggests incomplete refactoring — mini-swarm meshes use hardcoded `OctahedronGeometry(size, 0)` detail level.
+**Fix:** Remove from import statement. Keep the constant in the model for future use.
+
+### Finding 3: Minimap display value inconsistency (LOW)
+**Location:** `services/minimap.service.ts:127,138`
+**Risk:** `show()` sets `display = ''` (CSS default), `toggleVisibility()` sets `display = 'block'`. Inconsistent — if CSS class has `display: none` by default, `''` would revert to `none` while `'block'` would override correctly.
+**Fix:** Normalize both to use `''` (let CSS class control default display).
+
+### Finding 4: Editor ngOnDestroy auto-save silent failure (MEDIUM)
+**Location:** `novarise.component.ts:1842-1846`
+**Risk:** `saveMap()` return value unchecked. If localStorage quota is exceeded during navigation-triggered auto-save, user silently loses unsaved editor changes with no notification.
+**Fix:** Wrap in try-catch, log warning on failure.
+
+### Verified NOT bugs:
+- StatusEffectService cleanup on restart: Already wired via `towerCombatService.cleanup()` → `statusEffectService.cleanup()` chain.
+- WebGL context restore: Three.js handles most GPU state restoration internally. Full scene rebuild would be overengineering.
+- Breakpoint inconsistency (768 vs 480): Intentional three-tier model (phone/tablet/desktop).
+

Minimap moves from top-left (crowded between HUD and tower bar) to
bottom-left corner. Tower bar now starts at 5.5rem (right below HUD)
instead of 11rem, using the freed vertical space.
