# Errors

## v0.0.5 Build Verification

**Date:** 2026-05-12  
**Error:** Docker Compose client version too old  
**Details:** `Error response from daemon: client version 1.42 is too old. Minimum supported API version is 1.44`  
**Resolution:** Docker client upgrade required on host. For now, used `python3 -m py_compile` to verify all Python files compile cleanly.

# Corrections & Insights

## Version Bump Strategy

**Context:** Task asked for version bump from 0.0.4 to 0.0.5 for 7 new monitoring summary endpoints.

**Decision:** Minor version bump (0.0.4 → 0.0.5) is correct per versioning rules in VERSION.md:
- New feature/page = minor bump
- Perf/refactor/fix = patch bump

All 7 summary endpoints are new features, so minor bump is appropriate.

## Endpoint Verification

**Status:** All 7 monitoring summary endpoints implemented by Neo:
1. `/api/v1/monitoring/cost-summary` ✅
2. `/api/v1/monitoring/cost-breakdown` ✅
3. `/api/v1/monitoring/health-summary` ✅
4. `/api/v1/monitoring/cron-summary` ✅
5. `/api/v1/monitoring/sessions-summary` ✅
6. `/api/v1/monitoring/sub-agents-summary` ✅
7. `/api/v1/monitoring/trends` ✅

**Verification Method:** Read `monitoring.py` API router to confirm all endpoints present with correct signatures and schemas.

## Python Compilation Check

**Command:** `find src/backend/app -name "*.py" | xargs python3 -m py_compile`

**Result:** No errors. All 50+ Python files compile cleanly.

**Note:** This is the most reliable verification when Docker Compose is unavailable due to client version incompatibility.

## Documentation Updates

**Files Modified:**
- `src/backend/app/core/version.py` — version changed from 0.1.0 to 0.0.5
- `VERSION.md` — added v0.0.5 entry documenting 7 summary endpoints
- `README.md` — API reference table updated to show all 12 endpoints as Live, status section updated to reflect v0.0.5
- `HISTORY.md` — added v0.0.5 changelog with all additions
- `FUTURE.md` — marked all 7 summary endpoints as DONE with completion dates and implementer (Neo)

## Build Workarounds

When Docker Compose is unavailable due to version mismatch:
1. Use `python3 -m py_compile` to verify all Python files compile
2. Check for import errors manually if needed
3. Document the issue and workaround for future reference
4. Note in version history that build verification was partial due to environment constraints
