# BRIEFING — 2026-10-02T02:44:00Z

## Mission
Review and adversarially challenge Milestone 2 Static Linter & Unit Test Implementation for i18n event bus & hygiene.

## 🔒 My Identity
- Archetype: reviewer-critic
- Roles: reviewer, critic
- Working directory: c:\Projects\FreeExile\.agents\teamwork\reviewer_i18n_m2_1
- Original parent: 0361e281-a64e-4264-a674-2b16c804009d
- Milestone: Milestone 2 Review
- 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)
- Issue clear verdict: APPROVE or REQUEST_CHANGES
- Send report and coordination message to orchestrator_13

## Review Scope
- **Files to review**: tools/lint/check_i18n_hygiene.py, tests/unit/test_i18n_event_bus.py, tests/e2e/test_i18n_reactive_switching_e2e.py
- **Interface contracts**: c:\Projects\FreeExile\.agents\teamwork\orchestrator_13\PROJECT.md, c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md
- **Worker reports**: c:\Projects\FreeExile\.agents\teamwork\worker_m2_1\implementation_report.md, c:\Projects\FreeExile\.agents\teamwork\worker_m2_1\handoff.md
- **Review criteria**: correctness, line count caps, style, conformance, adversarial robustness, integrity

## Review Checklist
- **Items reviewed**:
  - `tools/lint/check_i18n_hygiene.py` (337 lines) — Rule 1, 2, 3 + CLI flags
  - `tests/unit/test_i18n_event_bus.py` (328 lines) — 23 unit tests across 5 groups
  - `tests/e2e/test_i18n_reactive_switching_e2e.py` (193 lines) — E2E zero-reload browser verification
- **Verdict**: APPROVE
- **Unverified claims**: None (all claims independently reproduced and verified)

## Attack Surface
- **Hypotheses tested**:
  - Linter fails when hardcoded Vietnamese text is present (Passed: caught and exited code 1)
  - Linter allows Vietnamese in comments and fallback params (Passed: exited code 0)
  - Linter catches missing/extra keys in 9-language catalogs (Passed: caught parity violations)
  - Linter catches dangling markup/template keys (Passed: caught 95 keys when catalog was empty)
  - Unit tests evaluate genuine ES modules and Node.js VM (Passed: no facade/dummy logic)
  - Backward regressions on existing test suites (Passed: 20/20 chat tests, 60/60 typography tests)
- **Vulnerabilities found**:
  - 3 Minor linter robustness findings (external paths in Path.relative_to, parameter comma parsing in fallback regex, multiline template literals)
- **Untested angles**: None

## Key Decisions Made
- Confirmed zero integrity violations across all deliverables.
- Issued verdict APPROVE with 3 minor non-blocking findings documented in review report.
- Prepared handoff.md and review_report.md.
