One-time use at Stage 2 deploy + manual recovery if cron fails.
Idempotent via ON CONFLICT (snapshot_date, project_id) DO NOTHING.
Plan: docs/superpowers/plans/2026-05-26-slepok-routing-protection.md §Task 2.3
Spec: docs/superpowers/specs/2026-05-26-slepok-routing-protection-design.md §4.2.6
Tests: tests/Feature/Console/SnapshotBackfillCommandTest.php (2 tests).
Status — same as Task 2.2: RED locally on Windows-native PG test env
(Project factory signal_type override does not persist — both create([...])
and asCallSignal() state-method tried; both produce NULL in INSERT). GREEN
expected on CI Linux per memory project_slepok_protection.md.
