# Complete - m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding

## Completion Time

2026-08-03

## Summary

Completed the workspace binding compiler/codec child after five review loops; final verdict PASS with the root-workspace containment defect closed.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_local_G06_1.log` | `code_review_cloud_G06_1.log` | FAIL | Required exact configured tool binding, deterministic safe payloads, concrete containment, exact receipts, and archive-aware dependency checks. |
| `plan_cloud_G07_2.log` | `code_review_cloud_G07_2.log` | FAIL | Required native Anthropic tool admission, explicit error rejection, the full operation/mutation matrix, and clean integrated verification. |
| `plan_cloud_G07_3.log` | `code_review_cloud_G07_3.log` | FAIL | Required parent-capable containment, direct native tool-slice support, and mandatory command content mapping. |
| `plan_cloud_G07_4.log` | `code_review_cloud_G07_4.log` | FAIL | Required correct containment when the canonical workspace root is `/` plus permanent root-workspace regressions. |
| `plan_cloud_G03_5.log` | `code_review_cloud_G03_5.log` | PASS | Root-aware containment and its existing-target/non-parent-capable regressions passed the full verification packet. |

## Implemented and Closed

- Made the generated containment comparison root-aware so canonical workspace `/` admits contained descendants without weakening non-root boundaries or symlink escape rejection.
- Added permanent coverage for an existing relative target and a non-parent-capable target with an existing immediate parent under root workspace `/`.
- Retained fresh nested-parent admission, missing-immediate-parent rejection, final/ancestor symlink escape rejection, and payload-correlation protection.
