## Overview

date=2026-07-30
task=m-openai-compatible-output-validation-filters/03_repeat_guard_s07_remote_evidence, plan=0, tag=OFR-S07-REMOTE-AUTH-0

## Roadmap Targets

- Milestone: `agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md`
- Milestone link: [Milestone document](agent-roadmap/phase/knowledge-tool-optimization-extension/milestones/openai-compatible-output-validation-filters.md)
- Task ids:
  - `repeat-guard`: rolling content/history/action repetition detection and safe continuation
- Completion mode: check-on-pass

## Archive Evidence Snapshot

- Task `02+01_repeat_guard` is preserved at `agent-task/archive/2026/07/m-openai-compatible-output-validation-filters/02+01_repeat_guard/` as `SUPERSEDED_INCOMPLETE`, without `complete.log` or roadmap completion.
- Its old live invocation is consumed. It sent no `IOP_OPENAI_API_KEY`, returned five HTTP 401 responses, produced no summary, and completed cleanup with providers idle and source unchanged.
- Do not reopen or recount task 02 logs. This task starts a clean plan/review history at plan 0.

## For the Review Agent

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

Compare each implementation item against the plan and verify that recorded output is sanitized and trustworthy.

1. Append one verdict and the task-03-only `review_rework_count` / `evidence_integrity_failure` signals.
2. Archive this review and plan to their `_0.log` destinations.
3. If PASS, write `complete.log`, move task 03 to the monthly archive, and report the `repeat-guard` completion event for runtime.
4. If required auth/live execution could not proceed without a user-controlled credential or renewed authorization, create the `external-execution` `USER_REVIEW.md` stop. Do not create another equivalent plan.
5. If a started live invocation failed, preserve the consumed invocation evidence and require explicit new authorization before any future invocation.

## Implementation Item Completion

| Item | Status |
|------|---------|
| [OFR-S07-REMOTE-AUTH-0-1] Prove the remote runner and authenticated caller path | [x] |
| [OFR-S07-REMOTE-AUTH-0-2] Capture one authenticated S07 invocation and cleanup | [ ] |

## Implementation Checklist

- [x] [OFR-S07-REMOTE-AUTH-0-1] Run the read-only remote source/runtime/provider/authentication preflight. Prove the credential matches an active principal-token hash and `/v1/models` returns HTTP 200 without printing credential material. If unavailable or rejected, record invocation count 0 and stop.
- [ ] [OFR-S07-REMOTE-AUTH-0-2] After every preflight assertion passes, start exactly one fresh 5-concurrent × 3 live invocation, validate the sanitized S07 summary and cleanup, and record only raw-free evidence.
- [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 task-03-only `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
- [x] Verify verdict, dimension assessment, and Required/Suggested/Nit classifications match.
- [x] Archive active review to `code_review_cloud_G08_0.log`.
- [x] Archive active plan to `plan_cloud_G08_0.log`.
- [x] Verify the Agent-Ops managed `.gitignore` block.
- [ ] If PASS, write `complete.log`, leave no active `.md` files, and move task 03 to `agent-task/archive/YYYY/MM/m-openai-compatible-output-validation-filters/03_repeat_guard_s07_remote_evidence/`.
- [ ] If PASS, report the `repeat-guard` completion event for runtime without directly changing roadmap state.
- [x] If external credential/authorization remains unavailable, create `USER_REVIEW.md` with `reason=external-execution` and do not create an equivalent follow-up.
- [ ] If WARN/FAIL for another reason, write the exact next filesystem state required by the code-review skill.

## Deviations from Plan

The first client-side shell construction transmitted an escaped remote variable expression and ended without a valid preflight result. It did not start the Go live test and is not used as evidence. The preflight was then executed with the exact plan variable semantics and returned the recorded `auth_source=missing` blocker. No source, configuration, runtime, provider, prompt, credential, or archived-task state was changed.

## Key Design Decisions

Stopped immediately after the declared credential source was unavailable. The blocked preflight counts as zero live invocations; no `/v1/models` authentication success, provider call, or live harness launch was inferred. A future attempt must first have an operator-provisioned remote credential available through the plan's approved environment or mode-0600-file source, then rerun the full preflight before starting exactly one fresh invocation.

## Reviewer Checkpoints

- Verify no raw token, token hash, prompt, response, SSE body, or private endpoint material appears in this artifact or tracked diff.
- Verify authentication was proven with the non-provider `/v1/models` probe before the live test started.
- Verify the live invocation count is exactly 1 on success, or 0 when preflight was blocked.
- Verify a started invocation was never retried.
- Verify the summary cardinality/uniqueness/capacity/result assertions and provider/process/source cleanup all passed.
- Verify task 02 remained archived incomplete and was not used to inflate task 03 routing or review history.

## Verification Results

### Remote source/runtime/provider/authentication preflight

Command:

```bash
# Executed the exact OFR-S07-REMOTE-AUTH-0-1 command in PLAN-cloud-G08.md.
# The credential-bearing remote command is referenced rather than duplicated here
# to avoid repeating private runner and credential-handling details in evidence.
```

Implementation evidence:

Exit status: `42`.

Sanitized stdout: `remote_preflight=BLOCKED auth_source=missing invocation_count=0`

Auth source class: `missing`. The preflight did not reach a successful authenticated `/v1/models` assertion. No credential material, credential path, hash, prompt, response, SSE body, or provider output was recorded. Live invocation count: `0`.

### Single authorized remote live invocation

Command:

```bash
# Not run: OFR-S07-REMOTE-AUTH-0-2 is gated by a passing authenticated preflight.
```

Implementation evidence:

Not started. The valid preflight returned `auth_source=missing` with exit status `42`, so the authorized live Go test was not launched. Invocation count remains `0`; there is no live test output to record. Resume only after the approved remote credential source is available and a new full preflight passes.

### Sanitized summary and cleanup

Command:

```bash
# Not run: summary and cleanup validation requires one successful authorized invocation.
```

Implementation evidence:

Blocked before invocation: `auth_source=missing`, `invocation_count=0`. No summary was read or printed, and no cleanup PASS line can be asserted. Resume condition: an operator-provisioned credential must be available through the plan's approved remote source; rerun the complete preflight, then perform one fresh live invocation and its sanitized cleanup validation.

### Tracked secret/raw evidence check

Command:

```bash
git diff --check
git status --short
```

Implementation evidence:

`git diff --check` completed without whitespace errors. The evidence file also passed a no-index whitespace check, and a filename-only raw-evidence pattern check returned `tracked_secret_raw_check=PASS`. No raw credential or live artifact was written to the task evidence. The working tree retains pre-existing task-02 archival moves and the reviewed source-test modification; they were not changed by this task.

## Code Review Result

- Overall Verdict: FAIL
- Dimension Assessment:
  - Correctness: Pass — the implementation stopped before provider execution when the approved credential source was unavailable, and the reviewer reproduced the same safe preflight outcome.
  - Completeness: Fail — the required authenticated S07 invocation, sanitized summary, and cleanup evidence are absent.
  - Test Coverage: Fail — deterministic local evidence tests pass, but the required live 5-concurrent by 3-run S07 verification was not executed.
  - API Contract: Pass — the attempted preflight preserves principal-token authentication and does not expose credential material.
  - Code Quality: Pass — the reviewed evidence harness and artifact contain no blocking code-quality issue.
  - Implementation Deviation: Pass — the discarded client-side shell construction did not start the live harness, and the valid retry followed the plan's zero-invocation blocker path.
  - Verification Trust: Pass — fresh reviewer checks reproduced exit status 42 with `auth_source=missing` and `invocation_count=0`; focused and package tests passed, and no claimed live success is present.
  - Spec Conformance: Fail — SDD S07 requires three capacity+1 live runs and sanitized repeat-or-not-reproduced evidence, which this task could not produce.
- Findings:
  - Required — `agent-task/m-openai-compatible-output-validation-filters/03_repeat_guard_s07_remote_evidence/CODE_REVIEW-cloud-G08.md:56`: OFR-S07-REMOTE-AUTH-0-2 is incomplete, so the PLAN final verification and SDD S07 Evidence Map are unsatisfied. Securely provision an active matching principal credential through the declared remote environment or approved mode-0600 file source, rerun the full authenticated preflight, then start exactly one fresh 5-concurrent by 3-run invocation and record only the sanitized summary and cleanup evidence.
- Routing Signals:
  - `review_rework_count=1`
  - `evidence_integrity_failure=false`
- Next Step: Archive the current pair and create an `external-execution` `USER_REVIEW.md` stop. Do not create an equivalent follow-up plan until the approved credential source is available.
