# `NebulaAPI.CompilerCheck`
[🔗](https://github.com/podCloud/nebula_api/blob/v0.7.1/lib/nebula_api/compiler_check.ex#L1)

Pure decision logic for the `:nebula` Mix compiler (`Mix.Tasks.Compile.Nebula`).

Kept separate from the compiler so it can be unit-tested without touching Mix or
`.beam` files: it works on already-extracted module attributes.

# `verify`

Verifies an app's modules. `modules_attrs` is a list of `{module, attributes}` where
`attributes` is the persisted attribute keyword list (as returned by
`module.__info__(:attributes)` or the `:attributes` beam chunk).

Returns one of:

  * `{:error, local_modules}` — modules with local methods on this build exist, but no module
    wired a server via `nebula_api_server/0` (those RPC workers would never start).
  * `{:warn, :server_without_methods}` — a server is wired but the app defines **no** `defapi`
    methods at all, so it can never serve anything (likely a leftover `nebula_api_server()`).
    Node-independent: an app whose methods are all *remote* on this build still has `defapi`,
    so it does NOT warn.
  * `:ok` — otherwise.

The caller formats the human message; this stays pure decision logic.
