Bridge test 'minimized identity may dispatch when WindowServer omits its entry' fails on main #50

PeekabooBridgeWindowMutationIdentityTests.swift:251 ("Expected minimized pinned close to reach the service") fails on every run of --filter PeekabooBridgeWindowMutationIdentityTests on main at 957d15e, with the full patch stack.

• It still fails with peekaboo-restore.patch's MutationProof change reverted.
• Window 77 doesn't exist in WindowServer, so it isn't leaking from real window state.
• Not yet checked on pure upstream 4.8.0. peekaboo-close.patch, which selects a close route from read-only evidence before input, is the first suspect.

Possibly related to #30 (upstream operation-count tests fail with the patch stack).
