## Overview

date=2026-08-03
task=m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding, plan=2, tag=REVIEW_API

## Archive Evidence Snapshot

- Prior plan: `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/plan_local_G06_1.log`.
- Prior review: `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/code_review_cloud_G06_1.log`.
- Verdict: FAIL with 5 Required, 0 Suggested, and 0 Nit findings; `review_rework_count=1`, `evidence_integrity_failure=true`.
- Required scope: consume ordered `ExecutionPreset.WorkspaceTools` alternatives; normalize actual OpenAI Chat and Anthropic tool definitions; preserve typed structured values; make command mapping deterministic; carry public/provider identities; emit executable canonical-workdir and realpath containment guards; evaluate configured result matchers for exact receipts; and accept exact active-or-archived predecessor evidence.
- Affected files: `apps/edge/internal/openai/workspace_tool_binding.go`, `apps/edge/internal/openai/workspace_tool_codec.go`, and `apps/edge/internal/openai/workspace_tool_binding_test.go`.
- Fresh evidence: the existing focused suite, race suites, executable-`TMPDIR` Edge suite, vet, formatting, and diff checks pass, but a transient reviewer matrix failed actual nested OpenAI shape, unrelated `get_weather`, raw structured content preservation, and arbitrary successful JSON rejection.
- Roadmap carryover: Milestone task `artifact-pair`, approved SDD scenario S06, and its canonical mapping, parent preparation, no-escape, exact receipt, reversed-order, missing-tool, and extra-tool Evidence Map rows remain unsatisfied until this repair 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-G07.md` → `code_review_cloud_G07_2.log` and `PLAN-cloud-G07.md` → `plan_cloud_G07_2.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS, preserve first-line `milestone-task=artifact-pair` metadata 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_API-1 Compile the preset-declared ordered binding | [x] |
| REVIEW_API-2 Encode deterministic calls and exact receipts | [x] |
| REVIEW_API-3 Close the regression and integration evidence gaps | [ ] — shared Edge regressions block the required race and Edge-wide commands |

## Implementation Checklist

- [x] Compile only preset-configured ordered workspace alternatives against normalized actual OpenAI Chat and Anthropic tool definitions, preserving the full immutable binding contract.
- [x] Encode structured and command calls without content corruption, map public/provider identities, enforce executable no-escape guards, and match configured exact receipts.
- [ ] Add the reviewer regression/variant matrix and run archived-dependency, focused, race, Edge-wide, vet, formatting, and diff verification exactly as written. Required race and Edge-wide commands ran but fail on unrelated shared Edge regressions listed below.
- [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-cloud-G07.md` to `code_review_cloud_G07_2.log`.
- [x] Archive active `PLAN-cloud-G07.md` to `plan_cloud_G07_2.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`.
- [ ] If PASS, write `complete.log` based on `agent-ops/skills/common/code-review/templates/complete-log-template.md` and leave no active `.md` files.
- [ ] If PASS, move active task directory `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/` to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/` and update this checklist at the final archive path.
- [ ] If PASS, preserve and report `milestone-task=artifact-pair` for runtime aggregation without modifying roadmap or directly calling `update-roadmap`.
- [ ] If PASS for split work, remove the empty active parent or verify it was kept due to remaining siblings/files.
- [x] If WARN/FAIL, write the next filesystem state matching the verdict and do not write `complete.log`.

## Deviations from Plan

No command or scope deviation was made. The required race and Edge-wide commands
were run exactly as planned, but cannot pass until the shared OpenAI/Anthropic
Hot Path regressions are repaired. Resume by rerunning those two commands after
the following failures no longer reproduce:

- `TestAnthropicNativeVirtualPresetPreservesPublicModelIdentity`:
  `fragmented_SSE`, `END_before_response_start_returns_provider_error`, and
  `BODY_before_response_start_preserves_raw_baseline`.
- `TestVirtualPresetModelHandlersPreservePublicIdentity/chat_completions`:
  provider response is missing required creation time.

## Key Design Decisions

- The compiler selects only the first complete preset-declared alternative by
  exact tool name and recursive schema matching; actual OpenAI Chat function
  wrappers and Anthropic `input_schema` shapes normalize to the same contract.
- Compiled operation schemas are deep-copied so subsequent mutation of decoded
  request tools cannot alter a request-local binding or its fingerprint.
- Structured arguments keep their original values and types. Command arguments
  use only the configured fixed argv template. The guard resolves the canonical
  workspace cwd and the existing target (or existing parent for a new target)
  through `realpath -e`, preventing final-component symlink escape before the
  caller executes an operation.
- A receipt must correlate an issued public or provider call id and satisfy the
  configured `{status,result}` matcher; opaque, error, arbitrary, and
  mismatched receipts remain unmatched.

## Reviewer Checkpoints

- The compiler consumes only configured ordered alternatives and normalizes actual OpenAI Chat and Anthropic tool definitions without lexical role inference.
- The selected immutable binding carries exact tool/schema, argument, result, parent-capability, and public/provider identity contracts in its fingerprint.
- Structured payloads preserve typed values; command payloads and executable canonical-workdir/realpath guards are deterministic and reject traversal/symlink escape.
- Exact receipts require the configured result matcher and issued identity/operation/path/payload/guard correlation; opaque or error-shaped results do not match.
- Tests do not inspect a workspace or execute a caller tool.

## Code Review Result

### Overall Verdict

FAIL

### Dimension Assessment

| Dimension | Assessment | Evidence |
|-----------|------------|----------|
| Correctness | Fail | The native Anthropic decoded tool type cannot be compiled, and an error-shaped result can satisfy the configured receipt matcher. |
| Completeness | Fail | The required S06 variant matrix and clean integrated verification are incomplete. |
| Test coverage | Fail | The permanent tests use a synthetic Anthropic map, cover only prepare/write operations, and omit the reviewer reproductions and required read/delete/result variants. |
| API contract | Fail | The compiler does not accept the actual native Anthropic `tools[]` representation used by the Messages ingress contract. |
| Code quality | Fail | Receipt normalization treats a positive subset match as exact even when the same result contains an explicit error. |
| Implementation deviation | Fail | The plan required actual decoded endpoint shapes, error-shaped receipt rejection, the full regression matrix, and every verification command to pass. |
| Verification trust | Fail | Fresh race and Edge-wide output still fails, and the Chat failure now reports `unhealthy_route` rather than the submitted `missing required creation time` evidence. |
| Spec conformance | Fail | SDD S06 requires canonical mapping for both protocols and deterministic exact receipt evidence before the artifact pair can advance. |

### Findings

- **Required** — `apps/edge/internal/openai/workspace_tool_binding.go:145`: `extractToolSchema` accepts only `map[string]any`, while native Messages decodes request tools as `[]anthropicTool` with `json.RawMessage` `InputSchema`. A reviewer test using the actual decoded type failed with `tool "write_file" is not present`. Accept both actual endpoint representations, decode/copy the typed Anthropic schema, and add a regression that passes the native decoded slice rather than a hand-built map.
- **Required** — `apps/edge/internal/openai/workspace_tool_codec.go:371`: `matchResultReceipt` applies only a recursive subset matcher, so `status=success` with `{"written":true,"error":"permission denied"}` is accepted as exact. Normalize explicit error signals before matching, reject trailing/invalid result data, and bind the receipt to a deterministic issued-payload correlation covering operation, path, arguments, and containment guard.
- **Required** — `apps/edge/internal/openai/workspace_tool_binding_test.go:11`: the promised S06 regression/variant matrix is incomplete. It uses a synthetic Anthropic map and exercises only prepare/write; it does not cover the actual native decoded type, read/delete, a reversed complete alternative selection, embedded error-shaped success, or issued path/payload/guard mismatch. Add permanent table-driven cases for the full configured operation and negative matrix without executing a workspace tool.
- **Required** — `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/CODE_REVIEW-cloud-G07.md:50`: the required race and Edge-wide commands still fail, so REVIEW_API-3 and the integrated S06 evidence remain incomplete. Repair or wait for the active shared Hot Path regressions, rerun every exact command on one checkout, and record verbatim output; the current Chat failure is `400 unhealthy_route`, not the submitted creation-time failure.

### Reviewer Verification Evidence

- Dependency probes: PASS with no output.
- `go test -count=1 ./apps/edge/internal/openai -run 'TestWorkspace(Tool|Command|Binding)'`: PASS.
- Reviewer reproducer using `anthropicTool{Name: "write_file", InputSchema: ...}`: FAIL; the configured tool is reported absent.
- Reviewer reproducer using `status=success` and `{"written":true,"error":"permission denied"}`: FAIL; the result is incorrectly marked matched.
- `go test -race -count=1 ./apps/edge/internal/openai ./apps/edge/internal/service`: FAIL in the three Anthropic native identity variants and Chat `unhealthy_route`; service passes.
- Executable-`TMPDIR` `go test -count=1 ./apps/edge/...`: FAIL in the same OpenAI package cases; all other Edge packages pass.
- `go vet ./apps/edge/...`, `gofmt -d` on the three workspace-binding files, and `git diff --check`: PASS with no output.

### Routing Signals

`review_rework_count=2`

`evidence_integrity_failure=true`

### Next Step

FAIL: invoke plan skill in prepare-follow-up mode; archive the current pair and materialize the freshly routed follow-up pair.
