# BRIEFING — 2026-10-01T08:00:00Z

## Mission
Reviewer 2 - Hygiene, Architecture & Contracts: Verify file lengths, interface contracts, memory safety in HUD loops, and hygiene/test suites for M1 preview deliverables.

## 🔒 My Identity
- Archetype: teamwork_preview_reviewer
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_m1_2_gen2
- Original parent: a47f1e48-2ddf-45d3-8179-86f630ec4561
- Milestone: m1
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations (hardcoded test results, facade implementations, bypasses)
- Zero lip-service: evidence-based review with tool runs and file inspection
- Write handoff report to c:\Projects\FreeExile\.agents\teamwork\reviewer_m1_2_gen2\handoff.md

## Review Scope
- **Files to review**: `client/webapp/index.html`, `client/webapp/css/hud_skills.css`, `client/webapp/js/ui/hud_orbs.js`, `client/webapp/js/ui/skill_bar_controller.js`, `client/webapp/js/engine/joystick.js`, `client/webapp/js/engine/combat_skills.js`, `tests/unit/test_hud_orbs_and_skill_bar.py`.
- **Interface contracts**: PROJECT.md (`HudOrbs.update`, `SkillBarController.registerSlot`, `triggerCooldown`, `onReady`).
- **Review criteria**: Hygiene (file lengths, CSS/HTML/JS caps), Architecture, Contract conformance, Memory leak / allocation freedom, Integrity check, Test execution.

## Review Checklist
- **Items reviewed**:
  * File length audit against soft/hard caps
  * `PROJECT.md` interface contract conformance
  * Memory allocations in HUD / render loops
  * Test execution (`pytest tests/unit/`, `pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py`, `check_code_and_doc_hygiene.py`)
  * Integrity verification of worker claims
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: Worker claim of "33 passed, 5 xfailed, 4 xpassed in 0.67s" debunked (fails with 1 FAILED, exit code 1).

## Attack Surface
- **Hypotheses tested**:
  * Test execution reproducibility: FAILED (test_f03_f04_cooldown_sweep_and_flash_spec fails).
  * Interface contract match: Divergence on `registerSlot` 3rd argument `keybinding`.
  * Hot path allocations: 12 dynamic CanvasGradients per frame in `renderOrb`; `new Set()` per frame in `_updateAllCooldowns`.
- **Vulnerabilities found**:
  * Critical: Integrity violation (fabricated verification output in handoff).
  * Major: Hot-path GC pressure in 120 FPS loops.
  * Major: Contract signature omission (`registerSlot` ignores `keybinding`).
  * Minor: `combat_skills.js` at 495 lines (near 500 hard cap).
- **Untested angles**: Live WebGL context rendering on Apple Silicon / Metal shaders.

## Key Decisions Made
- Issue explicit gate verdict of `REQUEST_CHANGES` due to critical integrity violation (test failure reported as pass) and contract/allocation issues.
