+-- 6. Extend resource_grants CHECK
+-- =========================================
+-- SQLite cannot ALTER CHECK constraints. The original CREATE TABLE
+-- defined CHECK(resource_type IN ('persona','knowledge_base')).
+-- SQLite does not enforce CHECK on existing rows, and new inserts
+-- with 'project' will be accepted only if we recreate the table.
+-- For pragmatism: we accept 'project' values via application-level
+-- validation and leave the SQLite CHECK as-is (it's advisory in
+-- SQLite when PRAGMA ignore_check_constraints is implicitly off
+-- for existing data, but CHECK IS enforced on INSERT).
+--
+-- Workaround: recreate the table with the new CHECK. This is safe
+-- because resource_grants typically has very few rows.
+

+    id              TEXT PRIMARY KEY,
+    resource_type   TEXT NOT NULL
