 ## Status
 
-- Status: active
-- Current phase: final verified product ready for independent review.
-- Next safe action: pin the clean committed diff, run independent standards/specification reviews, then integrate only through the approved safe source-checkout gate.
+- Status: complete
+- Current phase: verified, independently approved product fast-forwarded to local main.
+- Next safe action: after this record-only closure commit, run final sanity/reachability checks, remove the owned clean worktree/branch, and restore the unrelated file's Git visibility. Final housekeeping evidence is written to `/tmp/pi-present/fast-browser-performance-cleanup.json`.

 ## Review
 
-Review fixed point: final verified product commits against the fetched source base. Specification is the approved committed record. Standards sources are repository/global AGENTS.md plus fast-browser contracts.

-Two new read-only Git-capable `claim-verifier` sessions independently review standards and specification. All authors, parent, and worker identities are excluded. Parent pins base, product HEAD, clean status, tree, commit list and SHA-256 of `git diff --binary --full-index --find-renames <base>...<product-head> --`. Reviewers reproduce the digest. Accepted fixes go back to an implementer, followed by verification and fresh independent review.
+- Review base: `773c628512fdfdf5a139ae1b27833bea97d74255`; product HEAD: `54303e0b5d8d99dbd3556a7a97453157e7ed09fd`; product tree: `08de591daedd2b32a64d3e054097d9cdd040089d`.

+- Excluded mutators: parent and all worker sessions (`browser-hotpath`, `runtime-hotpath`, `performance-benchmark`). Stable worker session IDs were not exposed, so the worker profile was excluded.
+- Standards reviewer: `performance-standards-review`, read-only claim-verifier, session `01a0c515-7d1a-7680-9e5b-d16aa4202b6b`. Confirmed exact digest and APPROVED with zero findings.
+- Specification reviewer: `performance-specification-review`, independent read-only claim-verifier; stable session ID not exposed. Confirmed exact digest and APPROVED with zero findings.
+- Both reviewers and parent confirmed unchanged clean HEAD/tree/status before and after review. No remediation cycle was required. Specifications were this approved record and development contracts; standards were repository/global AGENTS.md and established fast-browser patterns.
+- Full brief and separate axis results are retained at `/tmp/pi-present/fast-browser-performance-review-brief.md` and `/tmp/pi-present/fast-browser-performance-review-results.md`. Closure changes only this record, outside the approved product fingerprint.
 
 ## Integration and rollback
 
-Commit checked slices locally, fetch source again and rebase only if needed, reverify any changed tree, then review. Fast-forward integration only. Existing untracked source material stays untouched; if the source checkout is still dirty, pause integration rather than moving or deleting it. Approval of omission does not authorize removing the unrelated file.
+Source was fetched again and remained at the pinned base; no rebase was needed. Both review approvals and the exact digest were rechecked before `git merge --ff-only feature/fast-browser-performance`, which succeeded on local main. Source main now contains the exact reviewed product.
 
-After safe integration, make one record-only closure commit, prove reachability, and remove only the clean owned worktree/branch. No push or publish. Rollback is a normal revert of focused optimization commits; retain benchmark tooling if useful. If batching fails acceptance, drop only its uncommitted owned changes through a reviewed non-destructive patch, preserving other slices and benchmark evidence.
+The user explicitly approved `temporary_local_exclude` through ask_user for the unrelated untracked `docs/local-decision-model-feasibility.md`: temporarily exclude that exact path, require a clean source checkout, fast-forward, close and clean up, then restore its original untracked visibility. No contents or tracked state may change. The initial and post-fast-forward SHA-256 are both `5bb4fbf4c77742d41a230d25d87c4e4fd607a5bd38851bf61c7eaf022ebfd86c`. Approval evidence is `/tmp/pi-present/fast-browser-integration-approval.md`.
+
+Product commit is the pinned HEAD above. The next commit touching only this record is the metadata-only closure commit; its ID is discoverable with `git log -1 -- docs/plans/fast-browser-performance.md`. Final sanity checks prove product/closure reachability and clean owned worktree state before normal `git worktree remove` and `git branch -d`. The final cleanup evidence file records actual results after this commit, including restored visibility and unchanged document hash. Only the explicitly owned worktree/branch and temporary local exclude entries are removed. No push, publication, installed-package change or Pi reload occurred.
+
+Rollback is a normal revert of focused optimization commits, retaining benchmark tooling if useful.

 - Browser-hotpath correction assignment: 15 minutes, same Python worker/test paths; before HEAD 12a6bb6, only owned red tests dirty plus parent doc. Implement single-dispatch close followed by bounded inventory reads under existing ACTION_TIMEOUT_SECONDS. Replace pinned helper's 300ms readiness sleep with <=25ms bounded monotonic polling for the exact same document.readyState == complete predicate and existing timeout, retaining error propagation. Add readiness regression tests before the fix. This changes private polling cadence, not API, security posture, postconditions or budgets. Before patch `/tmp/pi-present/performance-close-red.patch`.
