## Summary

Completed the Node-only S06 observability evidence contribution after three rework verdicts; final verdict PASS with no Required, Suggested, or Nit findings.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G05_4.log` | `code_review_cloud_G05_4.log` | FAIL | Required the complete four-fixture oracle, traversed hostile values, panic-safe terminal delivery, and numeric duration evidence. |
| `plan_cloud_G05_5.log` | `code_review_cloud_G05_5.log` | FAIL | Required complete hostile-value injection, post-handler duplicate-terminal rejection, and non-reconstructed verification evidence. |
| `plan_cloud_G06_6.log` | `code_review_cloud_G06_6.log` | FAIL | Required both tunnel response sentinels to traverse the request seam and removal of synthesized long-command result lines. |
| `plan_cloud_G06_7.log` | `code_review_cloud_G06_7.log` | PASS | Every tunnel sentinel traverses the captured runtime request, evidence is raw or an exact transcript reference, and all fresh reviewer verification passed. |

## Implementation and Cleanup

- Injected each tunnel `responseVal` through `ProviderTunnelRequest.Metadata` and asserted every hostile run, tunnel, adapter, target, session, header, body, metadata, request, and credential value at the captured runtime request boundary before leakage checks.
- Preserved the complete metric label and dedicated structured-log rejection scan, the four-fixture observability matrix, numeric duration evidence, panic isolation, exactly-once terminal checks, and repeated Node construction coverage.
- Replaced synthesized long-command summaries with exact transcript references and raw transcript integrity output.

## Final Verification

- `go version && go env GOMOD` - PASS; Go `1.26.2` and `/config/workspace/iop-s1/go.mod`.
- `gofmt -w apps/node/internal/node/liveness_observability_test.go && test -z "$(gofmt -d apps/node/internal/node/liveness_observability_test.go)"` - PASS; no formatting diff.
- `go test -count=20 -v ./apps/node/internal/node -run '^TestNodeLivenessObservability$'` - PASS; 402-line exact transcript at `/tmp/iop-node-liveness-observability-focused.log`, reviewer SHA-256 `6fb15a011a2c3049ad0136a5a0584e9552ddf459bd905b736a647bc25eb61b7e`.
- `go test -count=1 ./packages/go/execution ./apps/node/...` - PASS; all Node packages passed.
- `go test -race -count=3 ./apps/node/internal/node -run 'LivenessObservability|Watchdog|HealthEvidence'` - PASS; no race report.
- `go vet ./packages/go/execution ./apps/node/...` - PASS; no diagnostics.
- `IOP_DEV_RECONNECT_BIND_TIMEOUT=45 ./scripts/dev/edge-node-reconnect-diagnostic.sh` - PASS; 125-line exact transcript at `/tmp/iop-node-liveness-observability-reconnect.log`, reviewer SHA-256 `0d4ec880bed884a1cd3749072912e8ca40658aa3d4763b4f53676b395cc944ac`.
- `test -s ... && wc -l ... && sha256sum ...` - PASS; both transcripts are non-empty with 402 and 125 lines.
- `git diff --check` - PASS; no whitespace errors.

## Remaining Nits

- None.

## Follow-up Work

- None.
