-- An embedding profile's *contract* is immutable: representation, dimensions,

-- `lifecycle` is different in kind -- it records whether that fixed contract is
-- currently serving -- so it is the one column an update may touch, and only
-- along a legal transition.
--
-- The contract comparison neutralizes `lifecycle` in both row images and then
-- compares the rows as text. Comparing whole rows rather than listing protected
-- columns means a column added later is protected by default; comparing text
-- rather than jsonb also catches changes jsonb normalizes away, such as an
-- array rewritten with different dimension bounds.
--
-- The transition table is duplicated from `context-core::ProfileLifecycle` on
-- purpose: the Rust table governs the SQL-facing API, and this one governs
-- direct catalog writes, so the invariant survives a superuser bypassing the
-- API.

-- Drift self-healing writes. Retrieval functions run SECURITY INVOKER so that
-- source-table SELECT/RLS is enforced against the caller, which means a
-- non-superuser collection member holds no direct privilege on the private
-- catalog tables. When a dump/restore or table rewrite changes a source
-- table's oid, the query path detects the drift and refreshes the stored
-- metadata through these SECURITY DEFINER helpers so the write succeeds as the
-- extension owner.
--
-- Security: these helpers accept only identifying keys, never a caller-supplied
-- oid or attnum. Each re-derives the authoritative oid/attnum from pg_catalog
-- using the schema, table, and column names already stored in the private
-- catalog, so a call can only ever set the true current binding of the
-- already-registered source table. This is deliberate: accepting an oid would
-- let a collection member repoint _collections.source_table_oid at an unrelated
-- table they control, and the SECURITY DEFINER payload/backfill paths check
-- privileges by that oid while mutating the real table by name -- a
-- confused-deputy escalation. Each helper also re-checks owner-role membership
-- on SESSION_USER (defence in depth for direct calls) and pins search_path.
