**Status**: Investigation and empirical verification complete; writing handoff.md

## Completed Steps
- [x] Initialized DISPATCH.md and recorded dispatch message.
- [x] Created BRIEFING.md with mission, identity, constraints.
- [x] Created progress.md heartbeat.
- [x] Read reference handoffs: auditor_18_1, challenger_18_1, challenger_18_2, reviewer_18_2, ORIGINAL_REQUEST.md, PROJECT.md.
- [x] Inspected source files: `client/web_pc/index.html`, `client/web_pc/js/pc_main.js`, `client/webapp/js/engine/canvas_renderer.js`, `client/webapp/js/engine/combat_skills.js`, `client/webapp/js/audio/sfx_engine.js`, `client/web_pc/js/pc_input_controller.js`.
- [x] Empirically reproduced and verified both runtime exceptions via live test scripts:
  - `test_do_primary.py` -> `TypeError: sfxEngine.playWeaponSlash is not a function`
  - `test_targeted_findings.py` -> `["Cannot read properties of null (reading 'classList')"]`
- [x] Formulated exact DOM remediation for `#badge-iframe`.

- [x] Documented auxiliary fix for Spacebar dodge charge double-decrement in `pc_input_controller.js`.
- [x] Updated BRIEFING.md.

## Current Step
- Writing 5-component `handoff.md` with exact code diffs and step-by-step instructions.
