Separate table, not a user_id on the shared transcripts (ADR-021). ENABLE +
FORCE ROW LEVEL SECURITY with the migration-003 policy, user_id NOT NULL
ON DELETE CASCADE, typed error_kind, per-row serving endpoint, JSONB segments.
CHECK constraints: done => content, failed => error_kind.
Up and down are one commit: golang-migrate pairs them.
Mutation-checked: dropping FORCE, the policy, or the cascade each turn a test
red. FORCE is only observable structurally -- the app role is not the table
owner, so no behavioural test can see it.
