DS-X-009 already existed and covers the property-side RESTRICT-vs- CASCADE sweep completely (discovered during implementation -- it predates this plan and was missed during planning since only the catalog file was grepped for this ID, not the test file). Adds the missing unit-side piece: units(unit_id) has no RESTRICT references at all, only CASCADE (rent_config/payment_records/unit_occupants/ documents) and SET NULL (tasks/invites), so purgeUnit should never be blocked by an FK violation, unlike purgeProperty.
…og (NONE) DS-X-009 (property-side RESTRICT-vs-CASCADE sweep) already existed and passes live -- discovered during implementation, not written as part of this work. Adds DS-X-009b to the catalog for the newly-added unit-side sweep test, and reframes Finding #6 from speculative to confirmed with the observed outcome.

Summary
properties/unitsFKON DELETEbehavior with live, observed evidence.DS-X-009(the property-sideRESTRICT-vs-CASCADEsweep) already existed inCrossDatastoreIntegrationTest.ktand already passes — it predates this session's work and was missed during planning (only the catalog file was searched for this ID, not the test file). The plan's originally-proposed property-side tests were correctly dropped as redundant.DS-X-009b, confirmingunits(unit_id)has noRESTRICTreferences at all (unlikeproperties) — onlyCASCADE(e.g.rent_config) andSET NULL(e.g.tasks) — sopurgeUnitcan never be blocked by an FK violation, unlikepurgeProperty.DS-X-009/DS-X-009brows from speculative to confirmed.Demo
