## Overview

date=2026-08-03
task=m-iop-hot-path-one-shot-execution/07+02,04,06_route_selector_direct, plan=1, tag=REVIEW_API

## Archive Evidence Snapshot

- Prior plan: `agent-task/m-iop-hot-path-one-shot-execution/07+02,04,06_route_selector_direct/plan_local_G07_0.log`.
- Prior review: `agent-task/m-iop-hot-path-one-shot-execution/07+02,04,06_route_selector_direct/code_review_cloud_G08_0.log`.
- Verdict: FAIL with 3 Required, 0 Suggested, and 0 Nit findings.
- Required closure: connect real Chat/Messages preset output to the selector/direct runner; use pinned capability/health evidence and exact canonical control shapes; preserve actual provider response identity/usage instead of synthetic values.
- Affected files: the preset Chat/Messages handler branches, hot-path selector/dispatch/direct implementation, and their focused tests.
- Verification evidence: static reference search found `dispatchPresetTurn` called only by its direct unit test; fresh focused test/race/vet commands were additionally blocked by an out-of-scope concurrent compile error in `apps/edge/internal/openai/workspace_tool_codec.go` and must be rerun after the shared package compiles.
- Roadmap carryover: `route-selector,direct-flow`; SDD S03 requires deterministic no-prose structural routing and S07 requires real direct text/high-thinking/tool completion with no reserved artifact path.

## 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-G10.md` → `code_review_cloud_G10_1.log` and `PLAN-cloud-G10.md` → `plan_cloud_G10_1.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/07+02,04,06_route_selector_direct/`. 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_API-1 Wire production structural selection | [x] |
| REVIEW_API-2 Preserve direct wire metadata and coordinator state | [x] |

## Implementation Checklist

- [x] Connect real preset Chat/Messages provider results to structural selection using pinned capability/health evidence and exact canonical control shapes.
- [x] Complete direct text/reasoning/tool continuation and terminal responses with actual response identity/usage, stable public model identity, and no reserved artifact path.
- [x] Add handler-level regressions and run fresh focused, race, full Edge, vet, formatting, deterministic reference, and diff verification after the shared package compiles.
- [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_G10_1.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G10_1.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/07+02,04,06_route_selector_direct/` to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/07+02,04,06_route_selector_direct/` and update this checklist at the final archive path.
- [ ] 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`.
- [ ] If PASS for split work, remove empty active parent `agent-task/m-iop-hot-path-one-shot-execution/` or verify it was kept due to remaining siblings/files.
- [x] If WARN/FAIL, write the next filesystem state matching code-review verdict and do not write `complete.log`.

## Deviations from Plan

- The structural hot path is activated only when a preset has a selector and at least one canonical `WorkspaceTools` alternative. Selector-only legacy virtual presets retain their existing relay behavior because no canonical prepare/write operation contract exists to classify; inventing control roles for those presets would violate the exact-shape requirement.
- The command runner rejected the planned `rm -rf "$route_selector_tmp_dir"` cleanup before execution under its destructive-command guard. The Full Edge verification was rerun with the same validated `mktemp` target and `rmdir "$route_selector_tmp_dir"`; Go left the temporary directory empty, `rmdir` succeeded, and the test command exited 0.

## Key Design Decisions

- `collectPresetSelectorResult` is the single production collection boundary for normalized `RunEvent` output and tunnel OpenAI Chat / Anthropic Messages JSON or SSE. It consumes the selected handle before any caller bytes are committed and derives an immutable selector gate from the same `ProviderPoolDispatchResult.DispatchInfo`.
- Preset dispatch uses the canonical selector model-group binding rather than the public virtual model. The gate requires the selected run, node, provider, model group, execution path, profile driver, and protocol capability to match the admitted result.
- Reserved-control classification examines every structured argument and raw JSON path occurrence, then accepts only the configured `prepare` or `write` tool and its configured `ArgumentMap["path"]`. Arbitrary roles, conflicting sources, wrong issued paths, duplicate controls, mixed calls, and partial pairs fail before direct output.
- Direct responses carry the actual provider response ID, creation timestamp when reported, terminal reason, raw usage object, and Anthropic thinking signature. Only the model field is replaced with the stable public virtual model; no response IDs, timestamps, token counts, or issued-call hashes are synthesized.
- A direct tool response fingerprints the exact public assistant message and installs the public/provider ID mapping plus the sole continuation frontier before emitting the response. A final response transitions to terminal only after a successful write, and a second terminal transition is rejected.
- Handler regressions cover Chat tunnel and normalized results, Anthropic native and Chat-bridge results, JSON and SSE, text/reasoning/tool output, provider metadata, virtual-model echo, frontier/terminal state, and malformed reserved-control rejection.

## Reviewer Checkpoints

- Real preset Chat and Messages handler branches normalize the selected provider result and invoke structural selection; no helper-only path remains.
- The classifier consumes pinned capability/health evidence, validates canonical control roles and all path sources, and never parses prose.
- Direct tool output leaves exactly one coordinator frontier; direct final output creates exactly one terminal outcome.
- OpenAI/Anthropic IDs, terminal reason, and provider-reported usage are preserved; no synthetic token counts remain.
- Public model identity remains the requested virtual preset and no direct call or output contains `.iop/job/`.

## Code Review Result

- Overall Verdict: FAIL
- Dimension Assessment:
  - Correctness: Fail
  - Completeness: Fail
  - Test coverage: Fail
  - API contract: Fail
  - Code quality: Pass
  - Implementation deviation: Fail
  - Verification trust: Fail
  - Spec conformance: Fail
- Findings:
  - Required — `apps/edge/internal/openai/hot_path_dispatch.go:31`: `presetHotPathEnabled` requires at least one `WorkspaceTools` alternative, although `packages/go/config/execution_preset_config_test.go:19` establishes that a valid direct-only preset has no workspace tools. Both handlers join every preset ingress before this check, so this valid shape relays through the ordinary provider path and leaves the logical request `active` instead of entering `runDirectTurn` and reaching exactly one terminal. A fresh handler probe returned HTTP 200 with coordinator state `active`. Enable the structural/direct path for every admitted preset with a selector, reserve workspace-tool requirements for light candidates, and add Chat and Messages direct-only/no-workspace handler regressions that assert terminal state.
  - Required — `apps/edge/internal/openai/hot_path_selector.go:242`: `mappedControlPath` extracts the first `.iop/job` substring from the mapped path value instead of comparing the entire normalized argument with the issued path. Consequently, a pair whose plan argument is `prefix/.iop/job/<request_id>/plan.md` and whose review argument is exact is accepted as `light_exact_pair`; the reviewer probe reproduced that result. Compare the complete mapped path value with the exact issued job/plan/review path, retain all-argument reserved-path conflict scanning, and add prefixed, absolute, suffixed, and multiple-source rejection cases.
  - Required — `apps/edge/internal/openai/hot_path_dispatch.go:251`: when a tunnel response omits its provider response ID, collection substitutes the IOP-generated `RunID` and emits it as the public OpenAI response ID; the adjacent fallback also promotes a tunnel-frame timestamp to public `created`. A fresh handler probe accepted the missing-ID provider body and returned HTTP 200 with `"id":"run-pool-tunnel"`, contradicting the plan's actual-provider-identity/no-synthetic-metadata requirement. Keep transport/run correlation and frame timing separate from provider response metadata, fail the direct collection through the endpoint-standard error path when required public identity is absent, and add tunnel JSON/SSE regressions that distinguish provider IDs/timestamps from IOP run/frame metadata.
- Routing Signals:
  - review_rework_count=2
  - evidence_integrity_failure=true
- Next Step: Invoke the plan skill in `prepare-follow-up` mode with these raw findings, rerun isolated task routing, archive this pair, and materialize the routed follow-up pair. Do not write `complete.log`.
