CI's "Apply database migrations" failed with asyncpg UnsafeNewEnumValueUsageError: alembic runs the whole upgrade in a single transaction, so migration 039's INSERT used 'grok' in the same transaction that 038 added it — which Postgres forbids. Splitting into two migration files did not help (one transaction spans both). Wrap the ALTER TYPE ADD VALUE in op.get_context().autocommit_block() so the value commits before 039 (and any later migration) uses it. Still renders in offline --sql, so the enum-migration-parity test is unaffected.

"""Add 'grok' to the postgres modelprovider enum.
|
|
|
|
Grok (``ModelProvider.GROK`` — xAI's OpenAI-compatible grok-build-0.1) is a new
|
|
agent backend. Seeding its provider row (migration 039) and routing agents to it
|
|
requires the postgres ``modelprovider`` enum to carry the value. Mirrors the
|
|
enum-add pattern of migration 037; the row seed is split into 039 because a
|
|
newly added enum value cannot be used in the same transaction that adds it.
