task=m-iop-agent-chronos-extraction-decoupling/05+03_state_fixture, plan=0, tag=REFACTOR

## 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-G05.md` → `code_review_cloud_G05_0.log` and `PLAN-local-G05.md` → `plan_local_G05_0.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-iop-agent-chronos-extraction-decoupling/05+03_state_fixture/`. 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 |
|------|---------|
| REFACTOR-2 State schema와 sanitized full-category fixture | [x] |

## Implementation Checklist

- [x] Refuse to start until predecessor 03+02_inventory_closure has an exact PASS complete.log.
- [x] Define the complete versioned state schema and sanitized fixture for all 10 original logical state IDs plus the two D04 cache/temp addendum IDs, including malformed residual quarantine.
- [x] Validate JSON structure, exact manifest/addendum ID provenance, required state categories/quarantine invariants, and absence of host paths, credentials, and secrets.
- [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-G05.md` to `code_review_cloud_G05_0.log`.
- [x] Archive active `PLAN-local-G05.md` to `plan_local_G05_0.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-agent-chronos-extraction-decoupling/05+03_state_fixture/` to `agent-task/archive/YYYY/MM/m-iop-agent-chronos-extraction-decoupling/05+03_state_fixture/` 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-agent-chronos-extraction-decoupling/` 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

An independent pre-review audit found that the initial eight broad-category records did not prove one-to-one coverage of the original manifest's ten logical `state:` rows. The fixture/schema were strengthened in scope-compatible rework to 12 unique records: ten exact `original` IDs plus `state:cache-root` and `state:temp-root` with `d04-addendum` provenance. The same audit replaced Verification 1 with an exact-one PASS resolver and the sensitive scan with fail-closed exit handling. All revised commands were rerun; routing facts did not change.

## Key Design Decisions

1. **Schema versioning**: Fixed at `version: 1` with JSON Schema draft 2020-12. Bumping requires a future change to the record shape; the `const: 1` constraint enforces forward compatibility with downstream consumers.
2. **Manifest-addressable records**: Every record has a unique logical ID, repository-neutral bundle path and `source_manifest` provenance. The ten `original` IDs are set-equal to the immutable manifest state rows; only cache/temp use `d04-addendum`.
3. **Quarantine as a separate category**: The broken-residual record uses `category: "quarantine"` with `resumable: false` and a required `quarantine_reason`. The schema conditional enforces that quarantine records always carry a reason.
4. **Synthetic-only values**: All digests are deterministic 64-char hex placeholders, sizes are small round numbers, and no host paths or credential patterns appear anywhere in the fixture.
5. **Predecessor dependency**: `03+02_inventory_closure` was confirmed PASS via its archived `complete.log` before implementation began.

## Reviewer Checkpoints

- Fixture contains all ten original manifest state IDs exactly once, plus only the two declared D04 cache/temp addendum IDs.
- All 12 logical IDs and bundle paths are unique; broken residual is non-resumable quarantine.
- Tracked fixture contains no private host or credential material.

## Verification Results

> Paste actual stdout/stderr for every command below. Do not summarize or reconstruct output. If output is too long, record the deterministic saved-output file path and the exact capture command. Any replacement command requires a `Deviations from Plan` entry.

### Verification 1

Command: `bash -lc 'set -euo pipefail; mapfile -t predecessor_logs < <({ test ! -f agent-task/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log || printf "%s\n" agent-task/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log; find agent-task/archive -path "*/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log" -type f -print 2>/dev/null; } | sort -u); test "${#predecessor_logs[@]}" -eq 1; awk "BEGIN {in_summary=0; found=0} /^## Summary$/ {in_summary=1; next} in_summary && /^## / {in_summary=0} in_summary && /final verdict: PASS/ {found++} END {exit found==1?0:1}" "${predecessor_logs[0]}"; printf "%s\n" "${predecessor_logs[0]}"'`

_Actual stdout/stderr and exit code (or exact saved-output path and capture command):_

```
$ bash -lc 'set -euo pipefail; mapfile -t predecessor_logs < <({ test ! -f agent-task/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log || printf "%s\n" agent-task/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log; find agent-task/archive -path "*/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log" -type f -print 2>/dev/null; } | sort -u); test "${#predecessor_logs[@]}" -eq 1; awk "BEGIN {in_summary=0; found=0} /^## Summary$/ {in_summary=1; next} in_summary && /^## / {in_summary=0} in_summary && /final verdict: PASS/ {found++} END {exit found==1?0:1}" "${predecessor_logs[0]}"; printf "%s\n" "${predecessor_logs[0]}"'
agent-task/archive/2026/08/m-iop-agent-chronos-extraction-decoupling/03+02_inventory_closure/complete.log
```
Exit code 0. Exactly one active/archive predecessor completion artifact was resolved and its Summary final verdict was PASS.

### Verification 2

_Actual stdout/stderr and exit code (or exact saved-output path and capture command):_

```
VERIFICATION_3_PASS
```
Exit code 0. All 12 logical IDs and bundle paths are unique, required categories/provenance/digests are valid, and broken residual is non-resumable quarantine.

### Verification 4

Command: `bash -lc 'set -euo pipefail; manifest_ids=$(mktemp); fixture_ids=$(mktemp); trap '\''rm -f -- "$manifest_ids" "$fixture_ids"'\'' EXIT; awk -F "\t" '\''NR>1 && $2=="state" {print $1}'\'' scripts/fixtures/iop-agent-chronos-ownership-manifest.tsv | LC_ALL=C sort >"$manifest_ids"; jq -r '\''.records[] | select(.source_manifest=="original") | .logical_id'\'' scripts/fixtures/iop-agent-chronos-transfer-state-v1.json | LC_ALL=C sort >"$fixture_ids"; test "$(wc -l <"$manifest_ids")" -eq 10; cmp "$manifest_ids" "$fixture_ids"; test "$(jq -r '\''[.records[] | select(.source_manifest=="d04-addendum") | .logical_id] | sort | join(",")'\'' scripts/fixtures/iop-agent-chronos-transfer-state-v1.json)" = "state:cache-root,state:temp-root"; printf "VERIFICATION_4_PASS\n"'`

_Actual stdout/stderr and exit code (or exact saved-output path and capture command):_

```
VERIFICATION_4_PASS
```
Exit code 0. The ten `original` IDs are set-equal to the immutable manifest state rows, and the supplemental set is exactly cache/temp.

### Verification 5

Command: `bash -lc 'set -euo pipefail; set +e; rg -n '\''/home/|/Users/|token|credential|secret|private_key'\'' scripts/fixtures/iop-agent-chronos-transfer-state-v1.json; scan_rc=$?; set -e; case "$scan_rc" in 0) exit 1;; 1) :;; *) exit "$scan_rc";; esac; printf "VERIFICATION_5_PASS\n"'`

_Actual stdout/stderr and exit code (or exact saved-output path and capture command):_

```
VERIFICATION_5_PASS
```
Exit code 0 with no sensitive match. An `rg` I/O/error exit would fail the command.

## Code Review Result

- **Overall Verdict:** FAIL
- **Dimension Assessment:**
  - Correctness: Fail — the published JSON Schema accepts transfer records that the production exporter rejects.
  - Completeness: Fail — the versioned schema does not encode the planned read-only and quarantine/resumability invariants.
  - Test Coverage: Fail — the planned jq verifier accepts the same invalid contract variants.
  - API Contract: Fail — schema acceptance differs from `validateStateExport` and SDD S02's read-only state-transfer contract.
  - Code Quality: Pass — the fixture is readable, deterministic, and contains no debug or dead content.
  - Implementation Deviation: Pass — the recorded 12-record strengthening remains within the planned scope.
  - Verification Trust: Fail — fresh counterexamples prove that the semantic verifier is not a complete oracle for the schema contract.
  - Spec Conformance: Fail — SDD S02 requires a read-only full-state transfer with broken residuals quarantined as non-resumable.
- **Findings:**
  - **Required** — `scripts/fixtures/iop-agent-chronos-transfer-state-v1.schema.json:73`: align the JSON Schema with the actual transfer acceptance contract. It currently permits `mode: "read-write"`, permits non-quarantine records with `resumable: false`, and only requires a reason for quarantine without forcing quarantine records to be non-resumable. The planned jq verifier also accepts all three mutations, while `cmd/iop-chronos-transfer/main.go:812` and `cmd/iop-chronos-transfer/main.go:826` reject them. Constrain transfer mode and conditional resumability/quarantine semantics in the schema, then add deterministic positive and negative schema-contract verification so those counterexamples fail.
- **Routing Signals:**
  - `review_rework_count=1`
  - `evidence_integrity_failure=false`
- **Next Step:** Invoke the plan skill with these raw findings and current verification evidence to create the smallest freshly routed follow-up pair.
