# BRIEFING — 2026-10-02T02:35:00Z

## Mission
Design comprehensive opaque-box E2E test architecture & suite for FreeExile 6-Player Party, Social Engine, Safe Teleportation, and PoE2 Town Portal (R1-R5).

## 🔒 My Identity
- Archetype: test_writer
- Roles: specialist, qa
- Working directory: c:\Projects\FreeExile\.agents\teamwork\test_writer_e2e_1
- Original parent: bc45a740-aa86-45b5-8706-381960281bc6
- Milestone: PoE2 Spatial Zoning & Monster Encounter Architecture (E2E Testing Track)
- Updated parent: 914399d4-059b-422e-a9e6-44e1005de38a
- Updated Milestone: FreeExile Party & Social System, Safe Teleport & Town Portal (E2E Testing Track)

## 🔒 Key Constraints
- Test code ONLY — never modify implementation code. Escalate implementation bugs.
- Follow 4-Tier test methodology (Feature Coverage, Boundary & Corner Cases, Cross-Feature Combinations, Real-World Application Scenarios).
- Opaque-box: Exercise features via public entry points and public APIs.
- Progressive testability: Provide immediate signal for server and client rules.
- File length guidelines: <= 350 lines (soft cap), <= 500 lines (hard cap). Keep test structure clean.
- Deliverables: TEST_INFRA.md, tests/e2e_social_party/, TEST_READY.md, handoff.md, progress.md.
- Tier 1: >= 5 tests per feature across all core features (party lifecycle, nearby radius, exp scaling, item/curr quantity & rarity, 3 loot allocation modes, monster hp & defense scaling, friend lifecycle, status presence, guild roster, teleport channel & interrupts, 5-gate destination validation, 2-way town portal, 6-portal charges, boss encounter lockout, secret chamber lockout, death penalty).
- Tier 2: Boundary & Corner Cases (empty party, 6-player max boundary, 7th player rejection, boundary distances exactly 15.0m vs 15.01m, 5.0s allocation timer expiry edge, 0 remaining map portals, instant damage during cast, boss alive vs dead transition, offline friends, mutual block).
- Tier 3: Cross-Feature Combinations.
- Tier 4: Real-World Realistic Application Scenarios.

## Task Summary
- **What to build**: E2E test suite in `tests/e2e_social_party/` covering R1-R5 across 4 tiers, TEST_INFRA.md, TEST_READY.md.
- **Success criteria**: Comprehensive opaque-box test suite adhering to contracts in PROJECT.md and ORIGINAL_REQUEST.md, runnable via pytest, all syntax valid.
- **Interface contracts**: PROJECT.md § Interface Contracts, ORIGINAL_REQUEST.md ## 2026-10-02T02:12:28Z.
- **Code layout**: tests/e2e_social_party/ (modular test files <= 350 lines), TEST_INFRA.md, TEST_READY.md.

## Key Decisions Made
- Implemented modular 4-Tier test suite across 9 Python files in `tests/e2e_social_party/`, strictly keeping each file <= 268 lines (well below 350 lines Soft Cap).
- Created `test_harness_models.py`, `test_harness_portal.py`, and `test_harness.py` for decoupled progressive testability.
- Authored 106 tests across all 17 features: 85 tests in Tier 1, 11 tests in Tier 2, 5 tests in Tier 3, 5 tests in Tier 4.
- 100% test pass verified: `106 passed in 0.31s` via `pytest tests/e2e_social_party/ -v`.
- Published `TEST_INFRA.md` (160 lines) and `TEST_READY.md` (149 lines) at project root.
- Documented and escalated implementation bug in `server/world/game_design_matrix_seeder.py:54`.

## Artifact Index
- `c:\Projects\FreeExile\TEST_INFRA.md` — Test methodology & infrastructure specification
- `c:\Projects\FreeExile\TEST_READY.md` — Test readiness report & coverage checklist
- `c:\Projects\FreeExile\tests\e2e_social_party\` — Opaque-box E2E test suite directory (9 files, 106 tests)
- `c:\Projects\FreeExile\.agents\teamwork\test_writer_e2e_1\handoff.md` — 5-component handoff report
- `c:\Projects\FreeExile\.agents\teamwork\test_writer_e2e_1\progress.md` — Heartbeat progress report

## Loaded Skills
- None required explicitly by orchestrator prompt.

## Quality Status
- **Build/test result**: `106 passed in 0.31s` via `pytest tests/e2e_social_party/ -v`
- **Lint status**: 0 Hard Cap violations via `python tools/lint/check_code_and_doc_hygiene.py --strict`
- **Tests added/modified**: 106 tests in `tests/e2e_social_party/`
