Ar9av Parallel QA Orchestra — Concurrent Validation
Orchestrates 4 independent QA checks that run simultaneously, each on its own dev-server port. The refiner gets a single merged failure report with every issue in one pass, cutting the number of refine-iterate cycles needed.
When to use
Replace the sequential playtester → gap-checker calls in the main pipeline with a single call to this skill. Use after codesmith and the manifest-auditor + mobile-compat-checker linting passes.
The 4 workers
| Worker | Browser? | What it catches |
|---|---|---|
| static | No | BFS reachability, border holes, jump-arc gaps, spawn collision |
| golden-path | Yes (port A) | Boot, walk, jump, attack scenarios; win-condition reachability |
| fuzzer | Yes (port B) | Stuck state, spawn-trap, no-progress, out-of-bounds, NaN state |
| physics-debug | Yes (port C) | Hitbox misalignment, body offset bugs |
All 4 run concurrently. Total wall-clock time ≈ max(individual times) ≈ 30–45s.

Written to qa/orchestra-report.json. Also appended to state.qa[] (keeping last 5).
Exit code 0 if ok, else 5.
Port allocation
Each browser worker gets its own vite dev-server port. The script finds 3 free ports automatically using Node's net module before launching workers.
Integration with the pipeline
Replace steps 7–8 in the gameforge orchestrator:
// Before:
playtester → refiner (loop) → playtester (loop)
// After:
manifest-auditor → mobile-compat-checker → parallel-qa-orchestra → refiner (loop) → parallel-qa-orchestra (loop)
Max 3 refiner iterations, same as before.
Process
- Run
scripts/orchestrate_qa.mjs <project-dir> - Script allocates 3 free ports.
- Spawns 4 workers concurrently via
Promise.all+child_process.spawn. - Collects stdout JSON from each worker as it finishes.
- Merges into
orchestra-report.json. - Exits with combined pass/fail.
Scripts
scripts/orchestrate_qa.mjs <project-dir> [--no-physics]— run all 4 workers.--no-physicsskips the physics-debug worker (faster, loses hitbox checks).
