The engine handlers already enforce _IDENT_RE on output_var / var_binding / fixed values[].name via validate_payload, wired into every create/update/import through _validate_payload_for_type (returns 400 on ValueError). Existing tests cover leading-digit / dunder / too-long / empty cases; add the explicit comma scenario the user reported so the exact "no settle-delimiter in a var name" contract is regression-proof for all three module types. No production change — server gate already existed; this characterizes + locks it.

"""Payload validation coverage for every module kind.
|
|
|
|
Pins the contract that the API enforces ``handler.validate_payload`` at
|
|
every write boundary — POST /wp/api/modules, PUT /wp/api/modules/<id>,
|
|
POST /wp/api/modules/import-from-workflow, and the bundle endpoints when
|
|
a ``children[]`` array is part of the body.
|
|
|
|
The shape used per kind is intentionally minimal-but-valid for the
|
|
"happy path" and intentionally malformed in one specific way for each
|
|
rejection test so failure messages stay diagnostic.
