Status: Completed — Verdict APPROVE

## Steps
- [x] Step 1: Record dispatch to `DISPATCH.md` and initialize `BRIEFING.md`
- [x] Step 2: Formulate concrete empirical test plan
- [x] Step 3: Run unit tests and challenger edge cases (`test_hud_orbs_and_skill_bar.py`, `test_challenger_m1_edge_cases.py` -> 25/25 PASSED)
- [x] Step 4: Write independent empirical stress verification scripts verifying each previously reported bug (`test_challenger_gen3_empirical.py` -> 5/5 PASSED):
  - NaN/Infinity inputs into `HudOrbs.update` (PASSED)
  - Cooldown duration <= 0 and Infinity behavior (PASSED)
  - Charged skills (Dodge) 0 -> 1 recharge visual reset and flash (PASSED)
  - Key 'W' hotkey vs WASD collision (PASSED)
  - Rapid clicking / spamming (1000 spam calls) and concurrency (PASSED)
- [x] Step 5: Run full E2E test suite (`test_poe2_ui_animation_vfx_e2e.py` -> 33 passed, 9 xpassed)
- [x] Step 6: Run code and doc hygiene audit (`check_code_and_doc_hygiene.py --strict` -> PASS, exit code 0) and verify line caps (index.html 197, hud_orbs.js 335, skill_bar_controller.js 351, combat_skills.js 473, TEST_INFRA.md 123)
- [x] Step 7: Synthesize findings, update BRIEFING and write `handoff.md` with final verdict (APPROVE)
- [x] Step 8: Send completion message to parent
