# BRIEFING — 2026-10-02T02:55:00Z

## Mission
Implement Milestone 3 — Project Directives & Engineering Standards Documentation (R4) covering Cross-Platform Reactive i18n Protocol, Zero-Hardcoded UI strings, 9-language parity, and updating AGENTS.md, GEMINI.md, ENGINEERING_STANDARDS_2026.md, and GLOBAL_LOCALIZATION_DICTIONARY.md.

## 🔒 My Identity
- Archetype: worker_m3_1

- Milestone: Milestone 3

## 🔒 Key Constraints
- Exclusive write ownership files: docs/standards/ENGINEERING_STANDARDS_2026.md, AGENTS.md, GEMINI.md, docs/standards/GLOBAL_LOCALIZATION_DICTIONARY.md.
- DO NOT CHEAT. All implementations genuine.
- Document line limit: soft cap <= 400 lines, hard cap <= 600 lines.
- Clickable markdown links (`file:///c:/Projects/FreeExile/...`).

## Task Summary
- **What to build**: Engineering standards and project directives update for Cross-Platform Reactive i18n Protocol, 9-language parity, zero hardcoded strings, dictionary synchronization across 77 terms, pre-commit/CI tooling integration.
- **Success criteria**: All 4 files updated with required sections, line limits respected, hygiene checks pass 100%, handoff written, message sent to parent.
- **Interface contracts**: PROJECT.md, ORIGINAL_REQUEST.md
- **Code layout**: Root & docs/standards

## Change Tracker
- **Files modified**:
  - `docs/standards/ENGINEERING_STANDARDS_2026.md`: Added Section 3.6 (Event bus, zero hardcoded strings, 9-language parity, anti-regression gate, developer checklist) and updated Section 6.2. Length: 390 lines (<= 400 soft cap).
  - `AGENTS.md`: Added Protocol 14 in Section 3 and Core Rule 5 in Section 4.
  - `GEMINI.md`: Added Directive 5 in Section 1, Section 2.13 in Elite Code Standards, and updated Section 6.
  - `docs/standards/GLOBAL_LOCALIZATION_DICTIONARY.md`: Added Section 13 with all 77 keys synchronized across 9 languages in 5 categories.
- **Build status**: PASS (Exit Code 0)
- **Pending issues**: None

## Quality Status
- **Build/test result**: PASS — `check_code_and_doc_hygiene.py --strict` (0 errors), `check_i18n_hygiene.py --strict` (0 errors), 23/23 unit tests pass, 24/24 challenger tests pass.
- **Lint status**: 100% compliant, 0 violations.
- **Tests added/modified**: Validated against `tests/unit/test_i18n_event_bus.py`, `tests/unit/test_challenger_i18n_m1_parity.py`, `tests/unit/test_challenger_i18n_hygiene_adversarial.py`.

## Loaded Skills
- None explicitly assigned in dispatch

## Key Decisions Made
- Maintained `docs/standards/ENGINEERING_STANDARDS_2026.md` at 390 lines ($\le 400$ soft cap) by streamlining whitespace around dividers, completely eliminating doc hygiene warnings.
- Grouped 77 dictionary keys into 5 logical categories in `GLOBAL_LOCALIZATION_DICTIONARY.md` for maximum readability and accessibility across 9 languages.
