# Phase 14 Plan 02: Unraid API Connectivity Verification Summary

**Production-verified Unraid GraphQL API documentation with container ID format, myunraid.net network access pattern, and schema corrections**

## Performance

- **Duration:** 71 seconds (1 min 11 sec)
- **Started:** 2026-02-08T17:59:25Z
- **Completed:** 2026-02-08T18:01:16Z
- **Tasks:** 2 (1 complete in 14-01, 1 continuation task)
- **Files modified:** 1

## Accomplishments

- Documented container ID format: `{server_hash}:{container_hash}` (two 64-char SHA256 hashes joined by colon)
- Verified network access pattern: myunraid.net cloud relay URL is the working solution (direct LAN IP fails)
- Corrected schema documentation: `isUpdateAvailable` does not exist, `state` is UPPERCASE, `names` prefixed with `/`
- Documented n8n container configuration: UNRAID_HOST and UNRAID_API_KEY environment variables required
- Updated authentication pattern: environment variables instead of n8n Header Auth credentials (more reliable)
- Replaced all TBD placeholders in ARCHITECTURE.md with production-verified information

## Task Commits

Each task was committed atomically:

1. **Task 1: Document Unraid GraphQL API contract in ARCHITECTURE.md** - `1670e10` (docs) - *Completed in Plan 14-01*
2. **Task 2: Verify Unraid API connectivity end-to-end** - `d259b39` (docs)

## Files Created/Modified

- `ARCHITECTURE.md` - Added complete Unraid GraphQL API section with:
  - Container ID format specification (no longer TBD)
  - Network access findings (myunraid.net cloud relay)
  - Authentication pattern (environment variables)
  - n8n container configuration requirements
  - Container query with actual response structure
  - Schema corrections (state/names/isUpdateAvailable)

## Decisions Made

**1. Use myunraid.net cloud relay URL instead of direct LAN IP**
- **Rationale:** Direct HTTP (http://192.168.90.103) causes nginx redirect to HTTPS, which strips auth headers on redirect. Direct HTTPS (https://192.168.90.103:8443) does not have /graphql endpoint. The myunraid.net cloud relay URL properly handles GraphQL endpoint routing and preserves auth headers.
- **Impact:** Requires UNRAID_HOST to be set to myunraid.net URL format. The `host.docker.internal` approach documented in Plan 14-01 research did not work in production.

**2. Environment variables instead of n8n Header Auth credentials**
- **Rationale:** n8n Header Auth credential system was unreliable for GraphQL queries during testing. Direct environment variable reference in HTTP Request node header provides stable, testable configuration.
- **Impact:** n8n container requires UNRAID_HOST and UNRAID_API_KEY environment variables. HTTP Request node uses `genericCredentialType: "none"` and manual header with `$env.UNRAID_API_KEY`.

**3. Document schema discrepancies between research and actual API**
- **Rationale:** Phase 14 research incorrectly documented `isUpdateAvailable` field on DockerContainer type. Actual production testing revealed this field does not exist in Unraid 7.2 schema.
- **Impact:** Phase 15 will need to discover correct field for update status tracking via schema introspection. Documentation now clearly states schema differences from research.

## Deviations from Plan

None - plan executed exactly as written. User verification checkpoint resolved with comprehensive findings, all of which were documented in ARCHITECTURE.md as specified by the plan.

## Issues Encountered

None - verification checkpoint provided clear, complete information that was directly integrated into ARCHITECTURE.md.

## User Setup Required

**From Plan 14-01 (still applies):**
1. Create Unraid API key with DOCKER:UPDATE_ANY permission
2. Set UNRAID_HOST environment variable on n8n container (myunraid.net URL format)
3. Set UNRAID_API_KEY environment variable on n8n container
4. Update HTTP Request node configuration (genericCredentialType: none, allowUnauthorizedCerts: true)

**Note:** The credential creation approach changed from n8n Header Auth to environment variables, but the API key creation step itself remains the same.

## Next Phase Readiness

**Phase 14 Complete:**
- All INFRA requirements validated (INFRA-01: connectivity, INFRA-02: authentication, INFRA-03: container ID format)
- Container ID format documented and ready for Phase 15 mutation usage
- Network access pattern verified and documented
- Schema corrections provide accurate baseline for Phase 15 development

**Phase 15 Blockers:**
- None - all prerequisites met
- Phase 15 will need to discover correct update status field (isUpdateAvailable does not exist)

**Key Artifacts for Phase 15:**
- ARCHITECTURE.md Unraid GraphQL API section (complete contract documentation)
- Container ID format: `{server_hash}:{container_hash}`
- Working query: `query { docker { containers { id names state } } }`

## Self-Check: PASSED

**Modified files verification:**
```bash
✓ ARCHITECTURE.md exists
✓ Container ID format documented (server_hash:container_hash)
✓ myunraid.net cloud relay documentation present
```

**Commits verification:**
```bash
✓ 1670e10: Task 1 commit (from Plan 14-01)
✓ d259b39: Task 2 commit (document connectivity findings)
```

All artifacts documented in SUMMARY.md exist and contain expected content.
