# pi-crew v0.2.20 — Round 4 Test Results
**Date:** 2026-05-19
**Session:** After Bug #10 (API key filtering) and Bug #11 (spawn pi ENOENT) fixes applied
**Environment:** linux/x64, Node v22.22.0, Pi CLI v0.75.3, pi-crew v0.2.20

## Tests Performed

### Test 1: Foreground fast-fix team — VERIFY ✅
**Command:** `team action='run', team='fast-fix'`
**Goal:** Quick verification test after fixes

**Result:** ✅ PASS — 3/3 phases completed
- Phase 1 (explore): completed
- Phase 2 (execute): completed  
- Phase 3 (verify): completed
- Final status: `run.completed`

**Duration:** ~4 minutes

**Observation:** Foreground fast-fix team works correctly after Bug #10 and #11 fixes. The fixes did NOT break foreground execution.

---

### Test 2: Foreground default/implementation team — BLOCKED ⚠️
**Command:** `team action='run', team='default', workflow='implementation'`
**Goal:** Full comprehensive test with adaptive planning

**Result:** ⚠️ BLOCKED — `adaptive.plan_repair_failed`, `run.blocked`
- Planner (01_assess) completed successfully
- Planner produced a work item plan
- Adaptive plan repair failed → `run.blocked`
- Final events: `run.blocked`, `live_agent.terminated`

**Root cause of block:** The adaptive planning system tried to repair a missing/invalid plan but couldn't. This is a **workflow design issue**, not a code bug in the fixes applied. The implementation workflow expects the planner to produce a valid JSON plan in a specific format, and when that format is slightly off, the repair mechanism fails.

**Not a regression:** This same workflow has been blocking in previous rounds. It's related to how the planner agent generates plans for the implementation workflow.

## Bug Fix Verification Summary

### Bug #10 (MINIMAX_API_KEY filtered) — ✅ Fix Applied
- **File changed:** `src/runtime/child-pi.ts`
- **Fix:** Added allow-list to `sanitizeEnvSecrets()` to preserve model provider API keys
- **Verification:** Foreground works (uses parent env with API key intact). Background async cannot be fully verified until Pi restart due to Bug #11.

### Bug #11 (spawn pi ENOENT) — ✅ Fix Applied  
- **File changed:** `src/runtime/pi-spawn.ts`
- **Fix:** Added `resolvePiCliScript()` call for non-Windows platforms in `getPiSpawnCommand()`
- **Verification:** Foreground teams work because they don't need `getPiSpawnCommand()` (live-session uses same session). Background async cannot be fully verified until Pi restart.

## What Needs Pi Restart to Verify

1. **Bug #10 fix (API key):** The fix is applied to `child-pi.ts` but Pi must restart to reload the extension. Before restart, background workers fail with `spawn pi ENOENT` (Bug #11) which masks whether Bug #10 is fixed.

2. **Bug #11 fix (pi binary path):** The fix is applied to `pi-spawn.ts` but Pi must restart to reload. Before restart, background async runs fail with `spawn pi ENOENT` immediately.

**After restart:** Run `team action='run', async=true, goal="test background worker"` and verify workers produce output within 60 seconds (not 300s timeout).

## Key Findings This Round

1. **Bug #10 root cause identified:** `sanitizeEnvSecrets()` uses deny-list that filters `*_API_KEY*` vars. `MINIMAX_API_KEY` matches `api_key` pattern → filtered out → child Pi has no API key → hangs silently.

2. **Bug #11 root cause identified:** `getPiSpawnCommand()` returns bare `"pi"` on Linux/macOS (no PATH resolution), but Windows path resolution only. Detached background runner has minimal PATH → `pi` not found.

3. **Foreground execution is solid:** Fast-fix team (3 phases) completed successfully. Management features (doctor, validate, list, get, plan, settings) all verified working.

4. **Two separate failure modes for background workers:**
   - OLD (Bug #10): Workers spawn, run 5 min, timeout → This is the API key issue
   - NEW (Bug #11, current session only): Background runner can't find `pi` → `spawn pi ENOENT` immediately

**Next step:** Restart Pi to reload fixes, then run background async test.
