- oak-cli: new engine.rs assembly layer maps every facade call to module Rust APIs (oaknode graph/serializer, oaktimeline commands, oakrender ticket arena, oaktask ExportTask, oakcommon config); the ffi/optional/host layers and build.rs link config are gone - oak-worker: the worker session + POSIX shm transport moved into the crate (oakrender backend + serde_json control plane); no dylib - both binaries carry zero liboakengine references (otool verified); tests green (30 cli / 41 worker)

//! oak-worker: headless render worker process (Rust).
|
|
//!
|
|
//! The whole runtime lives in this binary (M14 R2): render backend
|
|
//! selection (dynamic -> OpenGL fallback through the oakrender crate's
|
|
//! direct Rust API), the startup handshake and the NDJSON control loop
|
|
//! ([`worker`], the port of `engine/src/capi/worker.cpp`), plus the
|
|
//! shared-memory frame-slot transport ([`ipc`], the port of
|
|
//! `engine/render/ipc/`). No `liboakengine` dylib is linked; the facade
|
|
//! keeps its own copies of both modules for the frozen
|
|
//! `oakengine_worker_*` / `oakengine_ipc_*` C ABI (external consumers).
|
|
//!
|
|
//! See README.md for the full status.
