Session 2's PersonProvisioner picked CrowdType::oldest() for the org —
silently wrong for multi-crowd_type orgs (Volunteer + Crew + Press are
three distinct crowd_types in one org). Schemas now declare their
target crowd_type explicitly via form_schemas.default_crowd_type_id.
RequiresDefaultCrowdType publish guard prevents misconfigured
event_registration schemas from publishing.
PersonProvisioner: oldest() fallback removed entirely. Misconfiguration
throws no_default_crowd_type at runtime; publish guard prevents it at
config time.
Migration uses a plain ulid() column without DB-level FK because
SQLite's table-rebuild on ALTER ADD FOREIGN KEY cascade-deletes
form_fields rows (form_fields.form_schema_id has cascadeOnDelete on
form_schemas). Application-level integrity via FormSchema::defaultCrowdType()
belongsTo + the publish guard + the runtime failsafe — three load-bearing
checks, none of which require the DB-level constraint.
Three pre-existing migration backfill tests bumped step counts +1 to
account for the new migration sitting between WS-5c and WS-5d:
FormFieldBindingMigrationTest (16→17, 14→15), FormFieldConfigBackfillAndDropTest
(11→12), FormFieldValidationRuleBackfillTest (14→15),
ConditionalLogicBackfillTest (5→6).
Six event_registration test fixtures updated to set default_crowd_type_id
to satisfy the new publish guard.
FormBuilderDevSeeder.resolveDefaultCrowdTypeId() — VOLUNTEER → first-active
→ create-as-needed fallback chain; documented contract for future seeders.
SCHEMA.md updated to v2.7.

Orchestrates per-purpose subject resolution + binding conflict
resolution + per-binding writes per RFC Q4/Q7/Q9. Per-binding failures
captured in BindingPassResult, not thrown — partial failures are
expected and recoverable. Catastrophic failures (no transaction,
unknown purpose, missing schema) throw FormBindingApplicatorException
and bubble.
Per-strategy null-winner matrix implemented via a NO_OP sentinel:
overwrite=write null, append=noop, replace=conditional, first_write_wins=
write only into null target. Append is collection-only with set-merge
semantics (deduplicated array_merge).
Identity-key bindings are skipped during apply — the subject resolver
already used them for lookup/provisioning; re-writing is a no-op or a
clobber.
Activity log hierarchical: one bindings_pass_completed parent +
N binding_applied children with parent_activity_id linkage (RFC Q12).
Failed bindings get error_class/error_message in their activity entry
in addition to their FormSubmissionActionFailure row (deliberate
dual source of truth).
