# 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

## Out of Scope

- TBD

## Test Results
