# Complete - m-node-provider-execution-liveness-recovery/13+10_recovery_observability

## Completion Time

2026-08-06

## Summary

Completed six artifact-pair iterations, including three official rework reviews, with a final PASS. The final test-only packet anchors the exact liveness metric contract and compares every bounded safe-log lifecycle row.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G08_0.log` | `code_review_cloud_G08_0.log` | N/A | Initial preparation pair; superseded before implementation or official review. |
| `plan_cloud_G08_1.log` | `code_review_cloud_G08_1.log` | N/A | Replanned preparation pair; superseded before implementation or official review. |
| `plan_cloud_G08_2.log` | `code_review_cloud_G08_2.log` | FAIL | Required explicit same-type sink coverage and a complete production-handler outcome matrix. |
| `plan_cloud_G04_3.log` | `code_review_cloud_G04_3.log` | FAIL | Required restoration of confirmed-only admission and exact HTTP, metric-schema, and safe-log assertions. |
| `plan_cloud_G05_4.log` | `code_review_cloud_G05_4.log` | FAIL | Required literal metric-family expectations and exact ordered safe-log row comparisons. |
| `plan_cloud_G04_5.log` | `code_review_cloud_G04_5.log` | PASS | Literal family-set and exact six-field lifecycle oracles close all remaining findings. |

## Implementation and Cleanup

- Added test-owned literal expectations for `iop_edge_liveness_recovery_eligibility_total` and `iop_edge_liveness_recovery_results_total`.
- Required the complete gathered family set, exact label keys and values, one series per positive family, exact count values, and zero families for the negative unconfirmed row.
- Added exact ordered six-field safe-log sequences for terminal, plan-rejected, redispatched, and dispatch-failed outcomes while retaining unsafe-key, sentinel, type, and generic-log suppression guards.
- Preserved the confirmed-only production recovery boundary and the test-only write scope of the final packet.

## Final Verification

- `test -f agent-task/archive/2026/08/m-node-provider-execution-liveness-recovery/10+09_stall_recovery/complete.log` - PASS; predecessor completion evidence exists.
- `gofmt -d apps/edge/internal/openai/liveness_recovery_observability_test.go` - PASS; exited 0 with no output.
- `go test -count=20 ./apps/edge/internal/openai -run '^TestOpenAILivenessObservationSink$'` - PASS; `ok iop/apps/edge/internal/openai 0.149s`.
- `go test -count=10 ./apps/edge/internal/openai -run '^TestOpenAILivenessRecoveryObservability$'` - PASS; `ok iop/apps/edge/internal/openai 0.203s`.
- `go test -count=1 ./packages/go/streamgate ./apps/edge/internal/openai ./apps/edge/internal/service ./apps/edge/internal/controlplane` - PASS; all four selected packages passed.
- `go test -race -count=3 ./packages/go/streamgate ./apps/edge/internal/openai -run 'LivenessObservation|LivenessRecovery|Observation'` - PASS; both packages passed with no race report.
- `go vet ./packages/go/streamgate ./apps/edge/internal/openai ./apps/edge/internal/service ./apps/edge/internal/controlplane` - PASS; exited 0 with no diagnostics.
- `IOP_VLLM_MODE=fake ./scripts/e2e-openai-vllm.sh` - PASS; credential-free OpenAI-compatible vLLM smoke passed.
- `IOP_DEV_RECONNECT_BIND_TIMEOUT=45 ./scripts/dev/edge-node-reconnect-diagnostic.sh` - PASS; three mock-provider runs verified registration, ordered payload equality, exactly-once terminal ordering, commands, and reconnect.
- `git diff --check` - PASS; exited 0 with no whitespace errors.

## Remaining Nits

- None.

## Follow-up Work
