+- [x] 2.1 Verify no regression to existing reconciliation behavior across the scheduler test suite
   - Confirm the full scheduler test suite passes with no new failures beyond any already-documented pre-existing ones, and that the pre-existing eager-capture tests in test_sim_reconcile_unaccounted.c and the JOBS_PUSH resync-merge tests in test_core_events.c continue to pass unmodified
   - Observable: full test suite result showing no regression, with the pre-existing eager-capture and resync-merge test names explicitly confirmed still passing
   - _Requirements: 1.2_
