Stop waiting if begin exits before CAS.
If the spawned begin returns before its first CAS, cas_calls never increases and this loop yields indefinitely. The test then times out instead of reporting the earlier failure. Wait for either the CAS checkpoint or task completion, with a timeout.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Validate the approval that begin returns.
If replace_scope revokes a tool grant without changing policy_ref, a repeated begin can return the existing Approved row at Line 490 before this check runs. consume_inner then denies that row because the grant no longer holds. Validate the returned row’s live authority on both the existing-row and newly published paths. Checking only the automatic value calculated for the new attempt does not cover an older row.

Preserve the scope if retirement is cancelled.
If the caller drops retire_scope while release_scope(...).await is pending, the removed entry never reaches the reinstatement branch. A later retirement returns Denied, so the subject cannot be released through a retry. Make the remove-and-release transition cancellation-safe, or retain a retryable retirement state until release completes.

There was a problem hiding this comment.
When a grant or automatic posture is replaced while persist awaits, the approved row has already been stored before this check rejects the racing call. A subsequent identical begin finds that row in existing_begin and returns early at lines 486–490 without calling automatic_stands, so an idempotent audit backend can still return the revoked row as Approved rather than creating a pending human request. Revalidate existing automatic rows against the live scope as well, or retire/replace the stale durable row before returning the race error. This contradicts the documented behavior that automatic approvals are revalidated before publication and that replacement revokes unsupported approvals.

tinysweeper found nothing blocking, but could not review everything, so this is not an approval: crates/tinysecurity-approval/src/engine.rs, crates/tinysecurity-approval/src/engine_scopes_tests.rs, crates/tinysecurity-bus/src/approval_scopes.rs.
