## Summary

The repository-neutral Chronos bundle exporter passed after four verdict-bearing review loops; the final verdict is PASS with exact manager-attempt ownership enforced for resumable route decisions.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G10_2.log` | `code_review_cloud_G10_2.log` | FAIL | Split owner state into exact disjoint logical payloads and replace workspace-boundary heuristics. |
| `plan_cloud_G10_3.log` | `code_review_cloud_G10_3.log` | FAIL | Enforce strict durable key and payload validation for every supported integration-record family. |
| `plan_cloud_G10_4.log` | `code_review_cloud_G10_4.log` | FAIL | Bind resumable route records to exact manager-owned attempt identities. |
| `plan_cloud_G10_5.log` | `code_review_cloud_G10_5.log` | PASS | Exact route ownership, integrity validation, quarantine behavior, and required regressions passed fresh review. |

## Implementation and Cleanup

- Retained the strictly decoded manager checkpoint long enough to derive the exact admissible `taskloop-route` keys from project, workspace, work-unit, and attempt identities.
- Required exact manager ownership and strict decision-envelope integrity before classifying a route record as resumable.
- Preserved orphaned, rebound, incomplete, and otherwise unmatched route records byte-for-byte only in `state:broken-residual-records` with `resumable=false`.
- Added end-to-end owned/orphan route regressions and representative invalid lifecycle-state coverage while preserving existing family validation and exact/disjoint payload behavior.

## Final Verification

- `go version && go env GOMOD` - PASS; `go1.26.2 linux/arm64` and `/config/workspace/iop-s1/go.mod`.

- Predecessor completion PASS assertion from plan Verification 2 - PASS with no stdout/stderr.
