+-- Migration 017: uploaded_transcripts — PRIVATE transcripts of audio a user
+-- uploaded themselves (ADR-033, tapir#33).
+--
+-- This is deliberately NOT the shared `transcripts` table (migration 015,
+-- ADR-021). That table is non-RLS on the explicit grounds that it holds only
+-- public caption content and nothing user-identifying. A recorded meeting is the
+-- opposite: private third-party content owned by exactly one user. Reusing
+-- `transcripts` — or adding a user_id to it with a partial policy — would put a
+-- private row in the one table the isolation test asserts is shared, and would
+-- pass CI green. A separate table keeps ADR-021's exception singular.
+--
+-- Row-level security follows migration 003 exactly: ENABLE + FORCE (the app
+-- connects as the table owner, which bypasses RLS unless forced), and a policy
+-- keyed off the per-request GUC tapir.current_user_id. With no GUC set the
+-- predicate is NULL and the table is deny-all.
+--
+-- The original audio is never stored (ADR-033): this row is all that is kept.
+-- segments holds the timestamped cues; re-transcribing 90 minutes costs ~7
+-- minutes, so discarding the timestamps would be irreversible.
