## GET /api/function-files

List function files.

**Query parameters**

- `limit` (optional): Page size (1–100, default 100).
- `after` (optional): Keyset cursor — return the page after this row (next page).
- `before` (optional): Keyset cursor — return the page before this row (prev page).
- `ids` (optional): Comma-separated list of IDs. Narrows results to these IDs within the caller's accessible scope (does not bypass access checks).
- `filter` (optional): Nested filter expression (`<Entity>Filter`): AND/OR/NOT + per-field comparison operators + relation traversal. JSON-encoded on the query string.
- `orderBy` (optional): Multi-key sort (`<Entity>OrderBy[]`): array of `{ field: direction }` applied in order. Directions: asc/desc plus the four explicit nulls variants. JSON-encoded on the query string.
- `version_id` (optional): Optional version narrower. Admins see every file when omitted; non-admin callers must scope by version.
