# BRIEFING — 2026-10-01T03:00:00Z

## Mission
Adversarially challenge and empirically stress-test multilingual lexicon (143 keys across 9 languages) and 14 Diátaxis wiki articles (VI, EN, ZH)

## 🔒 My Identity
- Archetype: empirical challenger
- Roles: critic, specialist
- Working directory: c:\Projects\FreeExile\.agents\teamwork\challenger_streamline_2
- Original parent: a8122c75-321a-4be0-bc44-2ff49f028481
- Milestone: milestone_streamlining_lexicon_wiki
- Instance: 2 of 2

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code
- Write and execute verification tests empirically; do not trust claims
- Strictly adhere to 5-component handoff report

## Review Scope
- **Files to review**: client/webapp/js/data/i18n_catalog.js, client/webapp/js/data/i18n.js, wiki/vi/, wiki/en/, wiki/zh/, wiki/README.md
- **Interface contracts**: c:\Projects\FreeExile\.agents\teamwork\orchestrator_3_gen2\PROJECT.md
- **Review criteria**: 143 keys parity across 9 languages, technical spec format (<=100 chars, 0 newlines), 1,000 rapid cycles, wiki articles & link resolution, unit/e2e/hygiene tests

## Attack Surface
- **Hypotheses tested**:
  - Key parity across 9 languages (all 143 keys): CONFIRMED PASS (143 keys across all 9 languages, 0 missing, 0 extra, 0 empty, 0 duplicate declarations).
  - 1,000 rapid language switching stress: CONFIRMED PASS (33ms total, 0 failures, 0 corrupted DOM elements, zero heap growth).
  - Description single-sentence technical spec format (23 keys across 9 languages = 207 strings): CONFIRMED PASS (max length 61 <= 100 chars, 0 newlines, 100% single sentences).
  - Interpolation & unicode escaping (\u007b, \u007d, {name}, {service}, {count}): CONFIRMED PASS.
  - Wiki article existence & markdown/anchor link resolution: CONFIRMED PASS (42 articles across VI, EN, ZH, 167 links verified, 0 broken).
- **Vulnerabilities found**: None that break specification. Nuance noted regarding decimal point normalization in non-Western languages (`0.25` in `zh`, `ja`, `th`).
- **Untested angles**: None within scope.

## Loaded Skills
- (None loaded)

## Key Decisions Made
- Constructed dedicated adversarial test harness `adversarial_i18n_wiki_test.py` (260 lines, <= 350 soft cap).
- Executed all 5 empirical tiers, E2E suite (60/60), Unit suite (16/16), and Hygiene gate (0 violations).
- Issued verdict: `APPROVE`.
