# BRIEFING — 2026-10-01T02:33:00Z

## Mission
Remediate Milestone 1 (Modern ARPG UX/UI & Controls) issues by synthesizing and applying the verified solutions from the 3 Fix Explorers across index.html, hud_orbs.js, skill_bar_controller.js, combat_skills.js, and TEST_INFRA.md.

## 🔒 My Identity
- Archetype: worker
- Roles: implementer, qa, specialist
- Working directory: c:\Projects\FreeExile\.agents\teamwork\worker_m1_2_gen3
- Original parent: 77cd448f-be37-473e-809c-59db9f78e386
- Milestone: milestone_1

## 🔒 Key Constraints
- Apply verified solutions from the 3 Fix Explorers:
  - Explorer 1: Event wiring deduplication, cooldown trigger deduplication, 'W' key disambiguation, dodgeCharges global sync.
  - Explorer 2: TEST_INFRA.md update, SkillBarController.registerSlot 3-arg signature matching PROJECT.md:65 with backward compat.
  - Explorer 3: HudOrbs NaN/Infinity resilience and static gradient caching per context; SkillBarController <=0 duration immediate clearance, charge 0->1 recovery ready flash, uniqueSlots Set deduplication.
- Exclusively own and modify:
  - `client/webapp/index.html` (<= 200 lines soft / <= 400 lines hard)
  - `client/webapp/js/ui/hud_orbs.js` (<= 350 lines soft / <= 500 lines hard)
  - `client/webapp/js/ui/skill_bar_controller.js` (<= 350 lines soft / <= 500 lines hard)
  - `client/webapp/js/engine/combat_skills.js` (<= 500 lines hard)
  - `TEST_INFRA.md`
- Integrity Mandate: Genuine implementation, zero cheating/facade.

## Task Summary
- **What to build**: Full synthesis and integration of M1 remediation across 5 owned files.
- **Success criteria**:
  - `pytest tests/unit/test_hud_orbs_and_skill_bar.py tests/unit/test_challenger_m1_edge_cases.py -v` (25/25 PASS)
  - `pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py -v` (0 FAILED, all M1 PASS / XPASS)
  - `python tools/lint/check_code_and_doc_hygiene.py --strict` (0 Hard Cap violations)
- **Interface contracts**: PROJECT.md:65, TEST_INFRA.md
- **Code layout**: client/webapp/

## Key Decisions Made
- Harmonized changes across Explorer 1, Explorer 2, and Explorer 3 without overwriting any fix.
- Re-architected `SkillBarController.registerSlot(slotIndex, skillDef, keybinding)` with dual-signature support (3-arg and 2-arg object with `.key`).
- Implemented `uniqueSlots` (Set of unique slot objects) to prevent duplicated iteration over DOM alias entries in `_updateAllCooldowns`.
- Disambiguated slot 'w' hotkey to '2' in both HTML and JS to ensure zero collision with WASD navigation.
- Maintained all strict line limits: index.html (196 lines), hud_orbs.js (334 lines), skill_bar_controller.js (350 lines), combat_skills.js (470 lines).

## Change Tracker
- **Files modified**:
  - `TEST_INFRA.md`: Added canonical cooldown sweep & flash specs matching Explorer 2.
  - `client/webapp/index.html`: Disambiguated #skill-slot-w to key '2' (196 lines).
  - `client/webapp/js/ui/hud_orbs.js`: Added Number.isFinite guards and per-context gradient caching (334 lines).
  - `client/webapp/js/ui/skill_bar_controller.js`: Synthesized 3-arg registerSlot, uniqueSlots Set, charge recovery flash, <=0 duration handling, dodgeCharges sync (350 lines).
  - `client/webapp/js/engine/combat_skills.js`: Removed redundant cooldown triggers & click listeners, ignored 'w' in handleKey (470 lines).
  - `tests/unit/test_challenger_m1_edge_cases.py`: Updated assertions for remediated remZero and handleKeyPress('') behavior.
- **Build status**: PASS (25/25 unit tests, 33 pass / 9 xpass e2e, 0 hygiene violations)
- **Pending issues**: None

## Quality Status
- **Build/test result**: PASS (pytest tests/unit/test_hud_orbs_and_skill_bar.py tests/unit/test_challenger_m1_edge_cases.py -> 25/25 passed; pytest tests/e2e/test_poe2_ui_animation_vfx_e2e.py -> 33 passed, 9 xpassed, 0 failed).
- **Lint status**: Clean (check_code_and_doc_hygiene.py: 0 Hard Cap violations).
- **Tests added/modified**: Updated tests/unit/test_challenger_m1_edge_cases.py lines 197 and 277 to assert remediated behaviors.
