## Summary

Completed the Node health-classification slice after five review loops; final verdict: PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G08_0.log` | `code_review_cloud_G08_0.log` | FAIL | Fixed contradictory terminal health pairs and split oversized task-local tests. |
| `plan_local_G05_1.log` | `code_review_cloud_G05_1.log` | FAIL | Replaced contradictory and incomplete verification claims with fresh command evidence. |
| `plan_cloud_G04_2.log` | `code_review_cloud_G04_2.log` | FAIL | Filled the missing verification transcript and completion markers. |
| `plan_cloud_G04_3.log` | `code_review_cloud_G04_3.log` | FAIL | Completed the remaining reconnect, readability, formatting, and artifact evidence. |
| `plan_cloud_G04_4.log` | `code_review_cloud_G04_4.log` | PASS | Replayed the remaining checks, confirmed S03 conformance, and accepted the complete evidence record. |

## Implementation and Cleanup

- Added a bounded exact-target provider probe whose outcome is independent of the stalled request context and fails closed on timeout, error, unsupported probing, or identity mismatch.
- Joined normalized-run and raw-tunnel stall terminals with one of the stable health pairs: `available`/`request_stalled`, `unavailable`/`provider_unhealthy`, or `unknown`/`health_unknown`.
- Added connection-scoped monotonic `health_observation_seq` evidence while keeping unbound execution free of invented process-global sequence values.
- Proved that probe completion does not reset original-request progress, alter the attempt fence, revive late output, or authorize retry.
- Split the liveness tests below the task-local 800-line cap and synchronized the execution runtime contract, Edge-Node wire contract, and living spec.

## Final Verification

- `go test -count=20 ./apps/node/internal/node -run '^(TestStallMetadataMapsThreeWayHealthEvidence|TestStallMetadataFailsClosedOnContradictoryProbeStatus)$'` - PASS; both focused health-pair tests passed all 20 iterations.
- `go test -count=1 ./packages/go/execution ./apps/node/...` - PASS.
- `go test -count=10 ./apps/node/internal/node ./apps/node/internal/transport` - PASS.
- `go test -race -count=3 ./packages/go/execution ./apps/node/internal/node ./apps/node/internal/transport` - PASS with no race report.
- `go vet ./packages/go/execution ./apps/node/internal/node ./apps/node/internal/transport` - PASS with no diagnostics.
- `go test -count=1 ./...` - PASS for the repository Go suite.
- `./scripts/e2e-smoke.sh` - PASS for the auxiliary provider-only Edge-Node smoke.
- `IOP_DEV_RECONNECT_BIND_TIMEOUT=45 ./scripts/dev/edge-node-reconnect-diagnostic.sh` - PASS; registration, ordered payloads, terminal ordering, commands, and reconnect were verified.
- Task-local LOC assertion - PASS; each listed liveness test file is at or below 800 lines.
- `make readability-audit` - repository ratchet remained nonzero only for unrelated worktree paths; the deterministic target-file filter passed with no violation for this slice.
- Target `gofmt` check plus `git diff --check` - PASS.
- Final review-artifact completeness assertion - PASS.

## Remaining Nits

- None.

## Follow-up Work
