Adds a `kind` column to paliad.proceeding_types (proceeding / phase /
side_action / meta) so the Mode B R3 Fristenrechner wizard, the
projects.proceeding_type_id binding, and the pkg/litigationplanner
snapshot can filter to primary proceedings only.
Implements the ratified design from docs/design-proceeding-types-
taxonomy-2026-05-26.md (m greenlit 2026-05-27 09:57 after the 11-question
AskUserQuestion round-trip).
Mig 153 is purely additive — ADD COLUMN with a safe DEFAULT, UPDATEs
reclassify 23 non-primary rows (4 phase + 10 side_action + 9 meta), and
a BEFORE INSERT/UPDATE trigger on paliad.projects backstops the new
invariant. Pre-mig audit (Supabase MCP, 2026-05-27) confirmed zero
downstream pressure on the 23 reclassified rows.
- internal/db/migrations/153_proceeding_types_kind.up.sql + .down.sql
- snapshot to paliad.proceeding_types_pre_153 in the same TX
- set_config('paliad.audit_reason', …) defensively
- DO-block asserts 23 reclassified rows before the trigger ships
- Q9 carve-out: is_active=false on every phase/side_action/meta row
- new trigger paliad.projects_proceeding_type_kind_check on
paliad.projects.proceeding_type_id
- internal/services/project_service.go
- extend validateProceedingTypeCategory to also enforce
kind='proceeding' AND is_active=true; new typed error
ErrInvalidProceedingTypeKind
- single SELECT picks up category + kind + is_active
- internal/services/project_service_test.go
- TestProjectService_ProceedingTypeKindGuard covers service-layer
rejection, the active-but-non-proceeding edge, mig 153 trigger
backstop, and the kind='proceeding' happy path
- cmd/gen-upc-snapshot/main.go
- filter proceeding_types query to kind='proceeding' for forward-
compat (the embedded UPC snapshot JSON regen requires DATABASE_URL
access and will land in a follow-up; the current placeholder is
already empty of non-primary rows)
