The auto-resolver cannot handle rename/rename conflicts (it expects the file at work/1_upcoming/ which no longer exists).

-# Story 256: Bot must verify other users' cross-signing identity before checking device verification
-
-## User Story
-
-As a Matrix user messaging the bot, I want the bot to correctly recognize my cross-signing-verified devices, so that my messages are not rejected when I have a valid verified identity.
-
-## Acceptance Criteria
-
-- [ ] The bot's `check_sender_verified` function (or equivalent) verifies the sender's identity trust status, not just individual device verification
-- [ ] When @yossarian:crashlabs.io (who has valid cross-signing keys) sends a message in an encrypted room, the bot accepts it instead of rejecting with 'no cross-signing-verified device found'
-- [ ] The bot still rejects messages from users who genuinely have no cross-signing setup
-- [ ] Existing tests (if any) continue to pass after the change
