advance_submissions.advance_section_id FK changed from cascadeOnDelete
to nullOnDelete; column made nullable. Aligns implementation with
RFC v0.2 §5.4 audit-immutability ("submissions remain for retention
compliance") — when ArtistEngagementObserver::deleted hard-deletes a
section, its submissions persist as orphans rather than disappearing.
Migration edited in place (branch unpushed, dev-only). Observer
docblock + test assertion updated to match. Removed pre-existing
follow-up comment that documented the deviation.

New Phase C test files:
- tests/Unit/Models/Artist/ArtistDomainModelsTest.php — relationships,
casts, soft-delete trait presence, slug uniqueness within/across
organisations, isParked() helper, AdvanceSection's primary scope,
PURPOSE_SUBJECT_FQCN['artist'] resolves to instantiable class.
- tests/Feature/Artist/ArtistEngagementObserverTest.php — auto-fill
organisation_id from artist, cross-tenant guard throws, soft-delete
cascades to performances + hard-deletes advance_sections.
- tests/Feature/Artist/PerformanceObserverTest.php — version starts
at 0, increments by 1 per UPDATE, no bump on no-op save.
- tests/Feature/Artist/ArtistDomainScopeLeakageTest.php — 5 scoped
models (Artist/Genre/Engagement direct + Stage/Performance FK-chain)
isolate cross-org queries.
- tests/Feature/Artist/ArtistTimetableDevSeederTest.php — fixture-count
smoke (4 stages, 12 stage_days, 6 artists, 12 engagements,
13 performances incl. 1 parked).
Cross-cutting fixes that Phase C surfaced:
- AppServiceProvider: morph-map block 2 extended with the 8 new
artist-domain models (artist_engagement, artist_contact, genre,
stage, stage_day, performance, advance_section, advance_submission).
Block 1 'artist' alias was already wired via PurposeRegistry.
- 5 form-builder backfill tests bumped --step rollback counts by +10
to account for the 10 new May 8 migrations sitting at HEAD between
the test's calibration point and current head.
- phpstan-baseline.neon regenerated (1631 entries) — all errors are
same patterns existing baselined code already exhibits
(Factory generic typing, Model property docblock gaps). Tracked
systematically under TECH-LARASTAN-* in BACKLOG.
Tests: 1646 passing (was 1624 pre-Session-1 → +22 net, no losses).
Larastan: 0 errors over baseline.
