"""Backend semantics tests for the scheduled-tasks fix.
Covers:
- DST-safe wall-clock math (spring forward + fall back) via zoneinfo
- End conditions (ends_at + max_runs) auto-disable the schedule
- Cost cap skips fires with a clear error
- Freeze-default on for new scheduled non-source-session creates
- Audit log captures field diffs
- /workflows/active surfaces in-process running runs
- Legacy timezone="local" coerced in memory at load
- Storage paused flag round-trips
- Month math no longer clamps to day 28
- Server-side escalation kicks tasks (and ack cancels them)
Run:
pip install -r backend/requirements.txt -r backend/requirements-dev.txt
cd backend && python -m pytest tests/test_workflows_semantics.py -v
