"""Per-project sandbox extensions/modules opt-in column.

The parameterized sandbox (docs/internal/specs/2026-07-13-sandbox-extensions-
on-the-fly.md) lets a venture declare the extensions/modules its sandboxed dev
DB should activate (e.g. ``{"postgres": ["vector", "postgis"], "redis":
["search"]}``). The provisioner activates them post-ready via ``docker exec``.
Additive and nullable: an unset service gets no extensions (bare), so existing
opted-in projects stay byte-for-byte unchanged on the bare path. Feature names
are allowlist-validated by the Project pydantic model before reaching here
(``SANDBOX_ENGINE_FEATURES``), so a ``plpython3u`` can never be persisted.
