"""Add 'awaiting_pr_review' to the postgres taskstatus enum.
|
||
|
|
|
||
|
|
The in-path PR-review gate (``Status.AWAITING_PR_REVIEW`` in
|
||
|
|
foundation/policy/lifecycle and ``TaskStatus`` in models/base) inserts a
|
||
|
|
reviewer sign-off between the assembled-PR submit and the PM merge. Persisting
|
||
|
|
a task in that state requires the postgres ``taskstatus`` enum to carry the
|
||
|
|
value. Mirrors migration 037's pattern (forward-only enum ADD VALUE).
|
||
|
|
|
||
|
|
Revision ID: 040_awaiting_pr_review
|
||
|
|
Revises: 039_seed_grok_provider
|
||
|
|
Create Date: 2026-06-20
|
||
|
|
|
||
|
|
NOTE: the revision id is kept well under 32 chars — alembic's
|
||
|
|
``alembic_version.version_num`` column is ``VARCHAR(32)`` and a longer id raises
|
||
|
|
``value too long for type character varying(32)`` when alembic records it.
