Overview

This PR fixes pause_match so it records the ledger sequence at which a match is paused, and uses that timestamp to enforce MAX_PAUSE_DURATION in resume_match and admin_resolve_stalled_match. Previously the Paused state carried no start time, so the max-pause-duration constant could not be applied.

Changes

⏸️ Pause Timestamp Tracking

• [MODIFY] contracts/escrow/src/types.rs

  • Added a paused_at_ledger: u32 field to the match data so the pause start ledger is persisted alongside the Paused state.

• [MODIFY] contracts/escrow/src/state_machine.rs

  • Set paused_at_ledger when transitioning a match to Paused.
  • Clear/reset the field on resume so stale timestamps are not reused.

• [MODIFY] contracts/escrow/src/lib.rs

  • pause_match now stores the current ledger sequence in paused_at_ledger.
  • resume_match and admin_resolve_stalled_match read paused_at_ledger and enforce MAX_PAUSE_DURATION.

• [MODIFY] contracts/escrow/src/tests/admin_stall_resolution.rs

  • Added a test covering the pause timestamp being recorded and the max-pause-duration enforcement path.

Verification Results

cargo test -p escrow admin_stall_resolution
✅ pause timestamp recorded and max-pause-duration enforcement covered

Acceptance Criteria	Status
Pause start ledger is recorded on transition to Paused	✅ paused_at_ledger set in pause_match
MAX_PAUSE_DURATION is enforced using the recorded timestamp	✅ Checked in resume_match and admin_resolve_stalled_match
Test added for the new behavior	✅ Added in admin_stall_resolution.rs

Closes #1792
