# BRIEFING — 2026-10-02T02:42:15Z

## Mission
Forensic Integrity Audit of Milestone 2 Implementation (I18n Event Bus, Reactive Switching E2E, I18n Hygiene Linter).

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: [critic, specialist, auditor]
- Working directory: c:\Projects\FreeExile\.agents\teamwork\auditor_i18n_m2_1
- Original parent: 0361e281-a64e-4264-a674-2b16c804009d
- Target: Milestone 2: I18n Event Bus & Reactive Switching

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- Strict compliance with ORIGINAL_REQUEST.md and PROJECT.md
- Binary verdict: CLEAN or INTEGRITY VIOLATION

## Current Parent
- Conversation ID: 0361e281-a64e-4264-a674-2b16c804009d
- Updated: 2026-10-02T02:39:07Z

## Audit Scope
- Work product: Milestone 2 implementation by worker_m2_1:
  - `tools/lint/check_i18n_hygiene.py`
  - `tests/unit/test_i18n_event_bus.py`
  - `tests/e2e/test_i18n_reactive_switching_e2e.py`
- Profile loaded: General Project
- Integrity Mode: development (per ORIGINAL_REQUEST.md ## 2026-10-02T01:42:06Z)
- Audit type: forensic integrity check

## Audit Progress
- Phase: reporting
- Checks completed:
  - [x] Read ORIGINAL_REQUEST.md and PROJECT.md
  - [x] Read worker reports (implementation_report.md, handoff.md)
  - [x] Static analysis & anti-pattern inspection
  - [x] Adversarial stress-testing of linter rule detection
  - [x] Run independent security audit
  - [x] Run code & doc hygiene check
  - [x] Run i18n hygiene linter
  - [x] Run unit test suite (23 tests)
  - [x] Run Playwright browser E2E test
  - [x] Run regression test suites (103 tests total)
- Checks remaining:
  - [ ] Write audit_report.md
  - [ ] Write handoff.md
  - [ ] Send message to orchestrator_13
- Findings so far: CLEAN

## Attack Surface
- Hypotheses tested:
  - Can unlocalized Vietnamese text evade `check_i18n_hygiene.py`? Tested with synthetic sample; correctly flagged with exit code 1.
  - Are unit tests mocking instead of evaluating real code? Evaluated `execute_node_test_harness()` in `test_i18n_event_bus.py`; directly imports `i18n.js` and `chat_ui.js` in Node.js VM.
  - Does E2E reload the page on language switch? Tested via `window.__sessionNavCount`; asserted 1 (zero reload).
- Vulnerabilities found: None.
- Untested angles: Fully covered across AST parsing, Node VM execution, and live browser automation.

## Loaded Skills
- None explicitly loaded

## Key Decisions Made
- Confirmed genuine implementation with zero anti-patterns; verdict: CLEAN.
