schema-column guard cannot see a migration in a module-level helper called from _post_init - false violation blocking #2048, and latent for every store whose _post_init delegates - #2993
Conversation
_post_init_added_columns now also resolves plain-name calls that a _post_init method makes to module-level FunctionDef/AsyncFunctionDef nodes in the same file, and collects their SQL literals too. A visited set keyed by function name prevents recursion (a helper that calls itself, or a cycle between two helpers). This fixes the false violation on agent_registry_store.py where the ALTER TABLE migration for sponsor_contact_id lives in _migration_v7_add_sponsor_contact_id, a module-level coroutine called from _post_init. The walker previously never descended into it because _post_init contains no SQL literals of its own -- it is eight await _migration_vN_*(self._db) calls. The fix: message now names both accepted shapes: the ALTER inline in _post_init, or in a module-level helper that _post_init calls. RED-FIRST proof for tsk-kwtvfq: Case (c) on BASE (before fix): ``` FAILED tests/scripts/test_check_schema_column_migrations.py::TestPostInitFollowsModuleHelpers::test_case_c_called_helper_goes_green ``` After fix, all three cases pass: ``` 5 passed in 0.37s ``` Cases (a) and (b) remain red on the fixed tree (verified by their individual test assertions), and case (c) now goes green.

Do not collect calls from nested bodies.
Line 469 traverses nested def, class, and lambda bodies. An uncalled nested function in _post_init can call a module-level migration helper. The checker then collects that helper's ALTER TABLE and accepts a migration that _post_init never executes.
Make _called_names use the same lexical boundary as _method_sql_literals. Add a regression case with an uncalled nested function that calls a module-level helper.
Proposed fix

WARNING: module_functions only captures top-level module functions directly in Module.body. Functions defined inside if/try/with/for blocks at module scope are missed, even though _post_init may legitimately call them. A helper defined inside a conditional block would not be followed, causing a false violation.
Reply with @kilocode-bot fix it to have Kilo Code address this issue.
Lead review — BOUNCED (1 blocking finding, measured)The deliverable itself is proven. I ran both guard versions over PR #2048's tree So the false violation is genuinely gone and no other store regressed.

fix-forward #2993 (tsk-kwtvfq): _called_names uses ast.walk, so an ALTER reached only from a never-executed nested def now silences the schema-column gate

CARD TITLE (intent, not commit subject): schema-column guard cannot see a migration in a module-level helper called from _post_init - false violation blocking #2048, and latent for every store whose _post_init delegates
Autonomous build of board card tsk-kwtvfq.
_post_init_added_columns now also resolves plain-name calls that a _post_init
method makes to module-level FunctionDef/AsyncFunctionDef nodes in the same
file, and collects their SQL literals too. A visited set keyed by function name
prevents recursion (a helper that calls itself, or a cycle between two helpers).
This fixes the false violation on agent_registry_store.py where the ALTER
TABLE migration for sponsor_contact_id lives in _migration_v7_add_sponsor_contact_id,
a module-level coroutine called from _post_init. The walker previously never
descended into it because _post_init contains no SQL literals of its own -- it
is eight await migration_vN*(self._db) calls.
The fix: message now names both accepted shapes: the ALTER inline in
_post_init, or in a module-level helper that _post_init calls.
RED-FIRST proof for tsk-kwtvfq:
Case (c) on BASE (before fix):
After fix, all three cases pass:
Cases (a) and (b) remain red on the fixed tree (verified by their individual
test assertions), and case (c) now goes green.
