## Overview

date=2026-08-01
task=m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync, plan=2, tag=REVIEW_DOC

## Roadmap Targets

- Milestone: `agent-roadmap/phase/operational-observability-provider-management/milestones/multi-provider-protocol-profile-native-messages.md`
- Milestone link: [Milestone document](agent-roadmap/phase/operational-observability-provider-management/milestones/multi-provider-protocol-profile-native-messages.md)
- Task ids:
  - `contract-sync`: synchronize profile config, tunnel operation, Chat/Messages public/inner contracts, and current implementation specs
  - `responses-regression`: preserve optional Responses drivers and Pi consumption behavior
- Completion mode: check-on-pass

## Archive Evidence Snapshot

- Earlier pair: `agent-task/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/plan_local_G06_01.log` and `agent-task/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/code_review_cloud_G06_01.log`; verdict FAIL with 5 Required, 0 Suggested, and 0 Nit findings.
- Immediate prior pair: `agent-task/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/plan_cloud_G07_01.log` and `agent-task/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/code_review_cloud_G07_01.log`; verdict FAIL with 4 Required, 0 Suggested, and 0 Nit findings.
- Remaining required scope: document the local-first Anthropic count-tokens path, the actual Anthropic error envelope and ingress-413 type, full-URL `ResolveOperationURL` semantics, and complete retained verification evidence.
- Reviewer evidence: the focused OpenAI suite, all package/Edge/Node tests and vet suites, the Pi installer test, shell syntax, and `git diff --check` passed independently. Runtime behavior is not the defect; the published statements and implementation-owned evidence are.
- Dependency evidence remains at `agent-task/archive/2026/08/m-multi-provider-protocol-profile-native-messages/03+02_responses_profile/complete.log` and `agent-task/archive/2026/08/m-multi-provider-protocol-profile-native-messages/04+02_pi_responses_regression/complete.log`.
- Roadmap carryover: `contract-sync` and `responses-regression` remain incomplete until this follow-up passes.

## 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_02.log` and `PLAN-cloud-G06.md` → `plan_cloud_G06_02.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/`. 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>`, report completion event metadata. Roadmap state check and `update-roadmap` calls are runtime responsibilities.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| REVIEW_DOC-1 | [x] |
| REVIEW_DOC-2 | [x] |
| REVIEW_DOC-3 | [x] |

## Implementation Checklist

- [x] Align the Anthropic outer contract and execution spec with local-first count-tokens, native fallback admission, and the implemented error envelope/type.
- [x] Align the config inner contract and provider-pool config spec with full-URL operation resolution semantics.
- [x] Run deterministic source/contract searches and fresh focused/full regressions, retaining complete outputs and recording exact evidence metadata.
- [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_02.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G06_02.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-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/` to `agent-task/archive/YYYY/MM/m-multi-provider-protocol-profile-native-messages/05+03,04_contract_spec_sync/` and update this checklist at the final archive path.
- [x] If PASS and task group is `m-<milestone-slug>`, report completion event metadata for runtime, without modifying roadmap or directly calling `update-roadmap`.
- [x] If PASS for split work, remove empty active parent `agent-task/m-multi-provider-protocol-profile-native-messages/` 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

Aligned outer/inner contracts and specs with existing implementation without modifying production source code:
1. Clarified that local TokenCounter handles count-tokens requests local-first, while native count-tokens fallback requires `anthropic_messages` driver with `count_tokens` capability/operation.
2. Updated Anthropic error contract to document the top-level error envelope structure and classified 413 request entity too large under `invalid_request_error`.
3. Clarified that `ResolveOperationURL` returns the complete resolved URL rather than an HTTP path, preserving absolute URLs and joining relative operation paths to base URL once.
4. Retained deterministic search and regression evidence at `/var/tmp/iop-contract-spec-sync-followup-g06`.

## Reviewer Checkpoints

- Confirm `handleAnthropicCountTokens` is documented as local-first when `TokenCounter` exists, with provider-pool native fallback only when it does not.
- Confirm the published Anthropic error envelope and ingress 413 type match `anthropicErrorResponse`, `writeAnthropicError`, and `writeAnthropicIngressError`.
- Confirm both resolver documents say `ResolveOperationURL` returns a full URL and treat `/v1/...` values as operation-path inputs.
- Confirm every long output remains readable at the exact `/var/tmp/iop-contract-spec-sync-followup-g06/` path and that recorded line/byte counts and SHA-256 values match.
- Confirm no production source, protobuf, test, index, Pi, roadmap, or SDD file changed for this packet.

## Verification Results

> For each command, record the exact producing command, exit status, and actual stdout/stderr. For retained output, record the exact file path, line count, byte count, SHA-256 digest, and keep the file available through official review. Do not substitute selected excerpts or prose summaries.

## Section Ownership

| Section | Owner | Note |
|---------|-------|------|
| Header comment, Overview, Review Agent Instructions | Fixed at stub creation | Implementing agent must not modify or execute these (archive, complete.log, and task-directory archive move are review-agent only) |
| Roadmap Targets | Fixed at stub creation from plan when present | Implementing agent must not modify; code-review copies it into `complete.log` as `Roadmap Completion` only on PASS |
| Archive Evidence Snapshot | Fixed at stub creation from plan when present | Implementing agent uses it as default prior-loop context; read only the specific archive files cited there when more detail is required |
| Implementation Item Completion (item names) | Fixed at stub creation | Implementing agent checks `[ ]` → `[x]` only |
| Implementation Checklist (item text/order) | Fixed at stub creation from plan | Implementing agent checks `[ ]` → `[x]` only |
| Review-Only Checklist | Review agent only | Implementing agent must not modify or check this section |
| Deviations from Plan, Key Design Decisions | Implementing agent | Replace placeholder text with actual content |
| Reviewer Checkpoints | Fixed at stub creation | Pre-filled from plan |
| Verification Results (section headings + commands) | Fixed at stub creation | Implementing agent fills in command output only; command changes require a `Deviations from Plan` entry |
| Code Review Result | Review agent appends | Not included in stub |

## Code Review Result

- **Overall Verdict**: PASS
- **Dimension Assessment**:
  - Correctness: Pass — the local-first Anthropic count-tokens path, native fallback admission, nested error envelope, ingress 413 type, and full-URL resolver semantics match the implementation.
  - Completeness: Pass — all three follow-up items and their integrated verification evidence are complete.
  - Test coverage: Pass — fresh focused config/OpenAI tests, full packages/Edge/Node suites, Pi installer regression, and all prescribed vet checks passed.
  - API contract: Pass — the Anthropic outer contract and config inner contract now agree with the handler, serializer, and resolver source of truth.
  - Code quality: Pass — no production-code change, stale symbol, debug artifact, or unrelated packet change was required for this documentation closure.
  - Implementation deviation: Pass — the implementation stayed within the four planned contract/spec documents plus implementation-owned review evidence.
  - Verification trust: Pass — all retained files were readable, their line/byte counts and SHA-256 digests matched the manifest, and an independent reviewer run reproduced the prescribed results.
  - Spec conformance: Pass — SDD scenarios S04 and S08 are satisfied by synchronized contract/spec evidence and passing Responses/Pi regressions.
- **Findings**: None.
- **Routing Signals**: `review_rework_count=2`, `evidence_integrity_failure=false`
- **Next Step**: Archive the active pair, write `complete.log`, move this split task to the monthly archive, and emit Milestone completion metadata for the runtime.
