# BRIEFING — 2026-10-02T03:04:00Z

## Mission
Milestone 4 Full-Suite Verification & System Certification across FreeExile reactive i18n and chat UI architecture.

- Milestone: Milestone 4 Full-Suite Verification & System Certification
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Actively check for integrity violations (hardcoded test results, facade implementations, shortcuts, fabricated verification, self-certifying work)
- If any integrity violations detected, verdict MUST be REQUEST_CHANGES with Critical finding tagged as INTEGRITY VIOLATION. Do NOT approve work that cheats.

## Review Scope
- **Files to review**:
  - `client/webapp/js/ui/chat_ui.js`
  - `client/webapp/js/data/i18n.js`
  - `client/webapp/index.html`
  - `docs/standards/ENGINEERING_STANDARDS_2026.md`
  - `AGENTS.md`
  - `GEMINI.md`
  - Worker handoffs: `worker_m1_1/handoff.md`, `worker_m2_1/handoff.md`, `worker_m3_1/handoff.md`
  - Test suites and linters
- **Interface contracts**:
  - `c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md` (section `## 2026-10-02T01:42:06Z`)
  - `c:\Projects\FreeExile\.agents\teamwork\orchestrator_13\PROJECT.md`

## Review Checklist
- **Items reviewed**:
  - Static linters: `check_code_and_doc_hygiene.py`, `check_i18n_hygiene.py` (both passed with code 0)
  - Unit & E2E batteries: 105 tests across 6 test suites + 80 regression tests (100% green)
  - Line caps: all code and doc files compliant with soft caps; `index.html` compliant with hard cap (252 <= 400)
  - Production code: `i18n.js`, `chat_ui.js`, `chat_i18n_catalog.js` (genuine implementation, zero hardcoded VI)
- **Verdict**: APPROVE
- **Unverified claims**: 0 remaining (all claims independently verified)

## Attack Surface
- **Hypotheses tested**:
  - Rapid sub-second language cycling (1,000 switches in Node, live burst switching in browser): PASS
  - Multi-byte non-Latin script veracity (ZH, JA, KO, TH, DE, RU): PASS
  - Static linter negative baselines (fault injection of VI strings, deleted keys, dangling tags): PASS
- **Vulnerabilities found**: 0 functional vulnerabilities. 1 minor note on `index.html` exceeding 200 lines soft cap due to concurrent tasks.
- **Untested angles**: None.

## Key Decisions Made
- Confirmed zero integrity violations across all deliverables.
- Verified live reactive browser switching with zero page reloads via Playwright.
- Certified system and issued APPROVE verdict.
