Copilot's round 16 reported "no new comments", but its suppressed block carried
three real findings.
- `AuthTab` released `clearInFlightRef` before checking whether the completion
was still current, so server A settling after the user moved to B and started
a clear there dropped B's lock and let a second B clear run concurrently
against the same store entry. `current()` is now checked before either shared
ref is touched: a stale clear owns nothing.
- Switching servers retired the clear but left `ownClearRef` set. The retired
clear returns before its `oauthRevision` bump, so the marker had no bump to
skip and would swallow the first unrelated revision on the newly selected
server, stranding that server's banner.
- The web session check compared only the server id, which a
disconnect/reconnect to the SAME server passes — that flow builds a
replacement `InspectorClient`, so the old clear would have run its
session-wide cleanup against the new session. The client identity is part of
the check now.
Both new tests were verified to fail with their fix reverted.
