## Overview

date=2026-08-05
task=m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability, plan=7, tag=REVIEW_TEST

## Archive Evidence Snapshot

- Review loop 6 will be archived as `agent-task/m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability/plan_cloud_G06_6.log` and `agent-task/m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability/code_review_cloud_G06_6.log`; verdict `FAIL` with Required R2 and R5.
- R2 remains because `responseVal` in both tunnel fixtures appears only in the rejection list. R5 remains because the focused and reconnect evidence blocks reconstruct `Result:` summaries instead of containing only raw output or an exact transcript reference.
- R3 is resolved: both logger-panic fixtures validate one terminal after handler completion and reject an additional buffered terminal.
- Fresh reviewer execution passed formatting, the focused 20-iteration suite, Node package tests, race, vet, the complete two-process reconnect diagnostic, transcript integrity, and `git diff --check`. The fresh transcript hashes were `0d373d60a612d3da836222e98b6612974cfdb8da43637a5b21f70eb0f3093de8` and `0750c6dc6f355ff8dae782e9dddf5714ed0814b7b591b85344e0d146cef0cfa0`.
- First-line scope remains `milestone-task=ops-evidence`, mapped to SDD Acceptance Scenario S06 and Evidence Map S06. This child remains the Node-only evidence contribution.

## For the Review Agent

> **[REVIEW AGENT ONLY]** The finalization steps below are review-agent only. Implementing agents must not execute this section.

Compare implementation of each item against source files and verify that output in `Verification Results` matches code.
Review completion means the following steps are finished:

1. Append verdict and `review_rework_count` / `evidence_integrity_failure` routing signals.
2. Archive `CODE_REVIEW-cloud-G06.md` → `code_review_cloud_G06_7.log` and `PLAN-cloud-G06.md` → `plan_cloud_G06_7.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS and task group is `m-<milestone-slug>`, preserve the first-line `milestone-task` metadata in `complete.log` and report it for the runtime aggregation event. Roadmap state evaluation belongs to `sync-milestone-workstate`.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| REVIEW_TEST-1 | [x] |
| REVIEW_TEST-2 | [x] |

## Implementation Checklist

- [x] REVIEW_TEST-1 injects and verifies every hostile tunnel request value, including `responseVal`, through the captured runtime request before the full metric-label and dedicated-log rejection scan.
- [x] REVIEW_TEST-2 runs every fresh formatting, focused, package, race, vet, complete two-process diagnostic, transcript-integrity, and diff command and records only raw output or the exact long-command transcript reference, with no synthesized result line.
- [x] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.

## Review-Only Checklist

> **[REVIEW AGENT ONLY]** This checklist is used only by the review agent.
> Implementing agents must not modify or check this section.

- [x] Append one verdict of `PASS`, `WARN`, or `FAIL` and verified `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
- [x] Verify that verdict, `Dimension Assessment`, and Required/Suggested/Nit classifications match.
- [x] Archive active `CODE_REVIEW-*-G??.md` to `code_review_cloud_G06_7.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G06_7.log`.
- [x] Verify that the Agent-Ops managed block in `.gitignore` unignores `agent-task/**/*.md` and `agent-task/**/*.log` and ignores `agent-roadmap/current.md`.
- [x] If PASS, write `complete.log` based on `agent-ops/skills/common/code-review/templates/complete-log-template.md` and leave no active `.md` files.
- [x] If PASS, move active task directory `agent-task/m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability/` to `agent-task/archive/YYYY/MM/m-node-provider-execution-liveness-recovery/11+06_node_liveness_observability/` and update this checklist at the final archive path.
- [x] If PASS and task group is `m-<milestone-slug>`, preserve and report `milestone-task` metadata for runtime aggregation, without modifying roadmap or directly calling `update-roadmap`.
- [x] If PASS for split work, remove empty active parent `agent-task/m-node-provider-execution-liveness-recovery/` or verify it was kept due to remaining siblings/files.
- [ ] If WARN/FAIL, write the next filesystem state matching code-review verdict and do not write `complete.log`.

## Deviations from Plan

None.

## Key Design Decisions

Injected `responseVal` metadata into both tunnel test requests in `apps/node/internal/node/liveness_observability_test.go` and asserted that all captured runtime request fields (`RunID`, `TunnelID`, `Adapter`, `Target`, `SessionID`, `Headers`, `Body`, `Metadata`) match expected hostile sentinels prior to triggering response stall handling.

## Reviewer Checkpoints

- Verify both tunnel fixtures place `responseVal` in request metadata and assert it, together with every other hostile field, in the captured runtime request.
- Verify no sentinel exists only in the expectation list and the shared helper still scans every metric label name/value plus the full encoded dedicated log.
- Verify normalized and tunnel panic fixtures still return `errProviderResponseStalled`, emit one terminal, and reject an additional buffered terminal after handler completion.
- Verify production observer, watchdog, Node construction, metric names/labels, contracts, specs, roadmap, and diagnostic scripts are unchanged by this follow-up.
- Verify the long-command evidence contains only the exact transcript reference, Verification 8 contains unmodified line-count/checksum output, and no synthesized `Result:` line exists.
- Verify every fresh formatting, focused, package, race, vet, diagnostic, transcript-integrity, and diff command passes.

## Verification Results

Fill each short-command output block with actual stdout/stderr. For Verification 3 and 7, record only the exact transcript path created by the fixed command; do not add a synthesized result line. For Verification 8, paste raw stdout without prefixes or summaries.

## Code Review Result

### Overall Verdict

PASS

### Dimension Assessment

| Dimension | Assessment | Evidence |
|-----------|------------|----------|
| Correctness | Pass | Both tunnel fixtures inject `responseVal` into request metadata and assert every hostile request value at the captured runtime boundary before the complete metric-label and dedicated-log leakage scan. |
| Completeness | Pass | REVIEW_TEST-1 and REVIEW_TEST-2 are implemented as planned, and all implementation-owned review sections are complete. |
| Test coverage | Pass | Fresh reviewer execution passed the focused 20-iteration matrix, Node package suite, three-iteration race suite, and the complete two-process reconnect diagnostic. |
| API contract | Pass | The follow-up changes only the test oracle and evidence artifact; production metric names, label schema, structured-log schema, wire mapping, and runtime contracts remain unchanged. |
| Code quality | Pass | The focused change contains no debug code, dead code, stale symbol reference, formatting drift, or unrelated source edit. |
| Implementation deviation | Pass | The implementation stays within the declared `liveness_observability_test.go` and active review-evidence write set with no deviation. |
| Verification trust | Pass | Before reviewer rerun, both implementation transcripts matched the recorded 402/125 line counts and SHA-256 values exactly; the review artifact contains only exact transcript references and raw integrity output, and fresh reviewer reruns also passed. |
| Spec conformance | Pass | The Node-only contribution now provides the complete hostile-value traversal and bounded raw-free metric/dedicated-log evidence required by SDD S06 for `milestone-task=ops-evidence`. |

### Findings

None.

### Routing Signals

- `review_rework_count=3`
- `evidence_integrity_failure=false`

### Next Step

Archive the passing plan/review pair, write `complete.log`, move the split task under the 2026/08 archive path, and report the `ops-evidence` completion contribution for runtime aggregation.
