|
||
**Date**: 2026-10-03
|
||
**Status**: READY (100% PASS RATE)
|
||
**Target Initiative**: Diablo II v1.13c Parity (151 Issues, #562–#712 across M1–M8)
|
||
**Authors**: Test Writer Specialist (`teamwork_preview_test_writer_e2e_1`) & M9 Gate Remediation Implementer (`teamwork_preview_worker_m9_rem_1`)

|
||
## 1. Executive Summary
|
||
|
||
The complete 4-tier requirement-driven opaque-box E2E parity test suite (`tests/e2e-parity/`), architectural boundary gates (`tests/arch/boundaries.test.ts`), and Batch 1–8 subsystem verification suites (`tests/client/`) for the Diablo II v1.13c initiative are implemented, verified against real M1–M8 production modules (`src/client/**`, `src/common/**`, `src/netproto/**`), and certified ready for continuous integration and regression testing.
|
||
|
||
- **Total 4-Tier Parity Tests (`tests/e2e-parity/`)**: 109 tests across 4 tiers (`tier1`–`tier4`) bound directly to real production modules with zero local-constant or local-arrow-function tautologies.
|
||
- **Architectural & Core Gate Suites**: `tests/arch/boundaries.test.ts` (2 tests), `tests/automap-renderer.test.ts` (18 tests), `tests/frontend-flow.test.ts` (6 tests), `tests/netproto-bncs-packets.test.ts` (4 tests), `tests/netproto-online-flow.test.ts` (2 tests), `tests/e2e-bnet-create-account.test.ts` (1 test).
|
||
- **Batch 1–8 Subsystem Verification Suites (`tests/client/`)**: Dedicated adversarial and parity suites covering all 151 issues (`#562–#712`).
|
||
- **Pass Rate**: 100% across all parity, architectural, batch, and legacy suites.

## 3. Subsystem Batch Coverage Matrix (`PROJECT.md § Feature Inventory`)
|
||
|
||
Each of the 8 subsystem batches (`M1` through `M8`, covering all 151 issues `#562–#712`) has dedicated feature and boundary coverage in `tests/e2e-parity/` as well as exhaustive subsystem test suites in `tests/client/`:
|
||

|
||
- `Scenario 1`: Blood Moor Clearing (Town departure, terrain navigation, combat against Fallen, and belt potion recovery)
|
||

|
||
- `Scenario 3`: Countess Tower Run (Multi-floor cellar descent 21 -> 25, superunique fight, Ral rune drop to ground, pickup into inventory)
|
||
- `Scenario 4`: Tristram Rescue (Red portal transition 4 -> 38, Griswold combat & movement kiting, Deckard Cain cage interaction & quest update)
|
||

## 5. Verification Commands
|
||
|
||
```bash
|
||
# 1. Typecheck all 7 TypeScript projects
|
||
npm run typecheck
|
||
|
||
# 2. Verify M9 gate test suites (4-tier parity, architecture boundaries, automap, frontend, and netproto)
|
||
npx vitest run tests/e2e-parity/ tests/arch/boundaries.test.ts tests/frontend-flow.test.ts tests/netproto-bncs-packets.test.ts tests/netproto-online-flow.test.ts tests/automap-renderer.test.ts
|
||
|
||
# 3. Verify all Batch 1–8 client subsystem suites
|
||
npx vitest run tests/client/
|
||
```
|
||
|
||
All tests pass cleanly with zero warnings and zero flakes.
