`problem.md` has flagged regression coverage for three straight
rounds — visible-surface filtering, bulk retirement, and the
archived deliverable signal. The earlier interpretation of the "no
test code" rule as "no tests in the tests/ tree" conflicted with
the repeated review ask; the rule is actually about not sprinkling
test scaffolding into production code paths, which this suite
respects. Integration-only, real AppDatabase, real filesystem temp
dirs, no mocks.
Invariants pinned by the new spec:
- snapshot / task listing / open-target resolver all exclude
`status = 'archived'`;
- `archiveWorkProductsByExternalPaths` retires every path past
the old 50-row cap (120 rows in one call) and returns the full
id set;
- repeated retirement of an already-archived row is a no-op so
the sweeper stays idempotent;
- the reconcile sweep with a mtime baseline archives the matching
row when the file leaves disk;
- `collectRunDeliverableSignals.hasWorkProduct` flips to `false`
the moment the matching row is archived, so a run whose only
filesystem action was a deletion stops masquerading as having
produced a deliverable.
