Status: Ready for integration

Integrate source commit b26001e039eaee51a3588f06194e0db9d8c72457 from task 20260902-account-permission-ui-6c9e21ad into the latest origin/main baseline.
Keep the source task record intact on its source branch, merge the account-permission UI correction and regression coverage, and record the integrated commit in canonical current state.
Run the required project-document and full repository verification, then advance origin/main with normal non-force pushes and verify its final commit.

The user explicitly authorized merging the completed account-permission UI fix into main and pushing it to the repository.
Preserve AUTH-001, all three roles, all 18 route-grant semantics, account ownership, APIs, and runtime behavior; this integration changes only the task-permission editor presentation, cache token, and regression coverage.
Keep every operation inside the exclusively owned integration worktree because the main checkout remains owned and contains another task's record.
Do not read .env, deploy, restart services, access ERP, or mutate real accounts, tasks, channels, database state, or other external runtime state.
Use a normal non-force push only after confirming origin/main has not advanced beyond the recorded base.

Verified that source commit b26001e is the sole commit above origin/main and that origin/main is its direct ancestor; the six-file source diff passed git diff --check.
Merged the source branch without conflict through merge commit 336ca6e7de9aba1123451a066902a520a3963563, keeping the source task record on its source branch as required by the Integration Gate.
Added the source and merge facts to canonical current state without changing AUTH-001 or business rules because the source task has no promotion candidate and preserves authorization semantics.
The fully merged tree passed repository hygiene, type checking, control-plane and legacy regressions, and production build.
Pushed integration tip 7c30676a1294077289bc59ce18bf39cae7b3b42a to origin/main without force and verified the remote branch returned the exact same commit.

Source task verification: focused account authorization 11/11, control plane 159/159, legacy 265/265, repository/type/build checks, and desktop/narrow browser geometry and pointer-interaction checks passed.
Integration source audit: origin/main was a618d3dd9fd8aa4e6f9a22e81b9b65452185b86a, source was b26001e039eaee51a3588f06194e0db9d8c72457, and git merge-base --is-ancestor origin/main <source> passed.
node --run check:repo: 10 passed, 0 failed.
node --run check: passed.
node --run test:control-plane: 159 passed, 0 failed.
node --run test:legacy: 265 passed, 0 failed.
node --run build: passed.
check_project_docs.py: passed.
check_doc_drift.py --task-id 20260902-integrate-account-permission-ui-e4c8a17b: passed after retaining the source task record only on its source branch.
git diff --check passed, and conflict-marker scanning returned no matches.
Fresh fetch before push confirmed origin/main remained at a618d3dd9fd8aa4e6f9a22e81b9b65452185b86a, with divergence 0 3 and remote as an ancestor of the integration tip.
The normal push advanced origin/main from a618d3d to 7c30676; git ls-remote --heads origin main, local HEAD, and the local origin/main tracking ref all returned 7c30676a1294077289bc59ce18bf39cae7b3b42a.

No runtime rollout is included; a service restart or deployment remains separately authorized work if needed.
