"""Guards for /outcome's stale sweep branch (Step 2c).

Pins the invariants for batch-resolving quiet applications:
- Step 0 documents `stale` / `sweep` and `stale <N>` / `sweep <N>`.
- Step 1.3 offers stale sweep when open rows exceed 60 days quiet.
- Step 2c defines the Stale Sweep Branch.
- Drafted applications are strictly excluded (never submitted).
- The default threshold is 60 days quiet.
- User confirmation (all, select, skip) is strictly required before writing.
- Status is resolved to canonical 'no_response' spelling.
