## Summary

Closed the provider-only canonical promotion boundary after three review loops with final verdict PASS.

## Loop History

| Plan | Review | Verdict | Notes |
|------|--------|---------|-------|
| `plan_cloud_G10_0.log` | `code_review_cloud_G10_0.log` | FAIL | Canonical promotion and its required verification matrix were not yet complete. |
| `plan_cloud_G10_1.log` | `code_review_cloud_G10_1.log` | FAIL | Canonical promotion passed, but three active descriptions retained standalone Agent or terminal-session ownership wording. |
| `plan_cloud_G08_2.log` | `code_review_cloud_G08_2.log` | PASS | Provider-only wording, focused regression, equivalent corrective commits, mirrored receipt, recovery evidence, and disabled-lock preservation were independently verified. |

## Implementation and Cleanup

- Replaced residual standalone Agent and terminal-session ownership descriptions with provider-only, run-scoped wording in both staging and canonical checkouts.
- Added `TestRootCmdUsesProviderOnlyDescription` and recorded equivalent four-path corrective commits with stable patch id `2e89dc0ed8a45542531af2e16efaf397dd3b2602`.
- Added both corrective commit identities and verification time to byte-identical staging and canonical `HANDOFF.md` receipts while preserving promotion, recovery, protected roadmap/UI, and lock evidence.

## Final Verification

- `TMPDIR="$PWD/.tmp" GOTMPDIR="$PWD/.tmp" go test -count=1 ./packages/go/execution ./apps/node/cmd/node` in both checkouts — PASS; fresh package and focused CLI tests succeeded.
- `go run ./apps/node/cmd/node --help` in both checkouts — PASS; the actual CLI entrypoint displayed the provider-only description and no Agent or terminal-session wording.
- `TMPDIR="$PWD/.tmp" GOTMPDIR="$PWD/.tmp" go test -count=1 ./packages/go/execution ./apps/node/...` in both checkouts — PASS; all Node packages succeeded.
- `TMPDIR="$PWD/.tmp" GOTMPDIR="$PWD/.tmp" go test -count=1 ./packages/go/execution ./packages/go/streamgate ./packages/go/config` in both checkouts — PASS; platform-common profile succeeded.
- `TMPDIR="$PWD/.tmp" GOTMPDIR="$PWD/.tmp" go test -race -count=1 ./packages/go/execution` and `go vet ./packages/go/execution` in both checkouts — PASS.
- Deterministic source and history closure checks — PASS; no forbidden ownership phrase remained, commit parents and four-path sets matched, stable patch ids were equal, indexes and unmerged sets were empty, and canonical-only credential support was preserved.
- Receipt and protected-state checks — PASS; `HANDOFF.md` and Agent UI mirrors matched, recovery commit objects and promotion ancestry remained available, `origin/dev` stayed at `c3a24ec5febab9fc978fd62392efcb6c96e12ec9`, and the Chronos dependency lock remained `disable`.
