The delegation tool carries its own CREATE TABLE for async_delegations
(tools/async_delegation.py _initialize_schema) plus a lazy ALTER TABLE
ADD COLUMN for the tables it finds already existing. Its column list
had drifted ahead of the canonical SCHEMA_SQL: origin_session_id
(raw api_server session id of the originating request, the wake
self-post target) existed only through the tool's lazy path, so two
databases at the same schema_version had different
async_delegations shapes depending solely on whether the delegation
tool had ever run. Rebuild/replay pipelines that reconstruct state.db
from the canonical schema then hit the column with no version gate to
explain it (#94691).
Declare the column in SCHEMA_SQL with the same TEXT NOT NULL DEFAULT ''
shape the tool uses. Fresh installs now carry it canonically; the
declarative _reconcile_columns backfills it into legacy databases on
the next writable open (same pattern as earlier additive columns); the
tool's lazy ALTER keeps serving pre-reconciliation databases. The two
schema authorities now agree, pinned by a test that runs the tool's
initializer over a canonical database and asserts the shape is
unchanged.
