📝 WalkthroughWalkthroughThe rate limit service now separates usage refresh from the request repository session. ChangesRate limit usage refresh
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR changes refresh sessions to run independently of the request scope. A localized test assertion does not definitively verify that the owned session closes before refresh, creating bounded risk of false confidence in session-lifetime coverage; the change is otherwise mergeable with explicit follow-up to correct that assertion.

The test no longer proves that the owned refresh runs without an open inner session.

One option: make the background doubles record enter/exit of a fake scope and assert the scope is closed while_refresh_account_if_staleruns.Also applies to: 196-203

136-139: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winThe
inner_session_closedevent does not prove the session closed.
InnerAccountsRepository.get_by_idsetsinner_session_closedwhen the account lookup runs. The lookup happens while the owned session is still open. Line 197 and thesession_was_open_during_refreshassertion therefore only prove that the lookup ran before the refresh finished. They do not prove that the owned session closed before_refresh_account_if_staleexecuted.Signal the event from the session teardown path instead, or rename the event to describe what it observes.

Problem
Client-cancellable rate-limit refreshes used caller-bound repositories while running singleflight work, and joined owned refreshes could leave account state stale.
