- 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-cli (Rust)
Headless command-line consumer of the oak editor module crates — the Rust
rewrite of cli/main.cpp (which stays in the tree until cutover). Same
subcommands, same output format, same exit codes:
| exit | meaning |
|---|---|
| 0 | success |
| 1 | general error (bad project/media file, no sequence, I/O failure) |
| 2 | rendering unavailable or failed (e.g. no render backend) |
| 64 | usage error |
Build and test
cargo build --release # binary: target/release/oak-cli
cargo test # unit + integration tests
The crate is self-contained (M14 R2): it links the oak* module rlibs
directly (oaknode, oaktimeline, oakcodec, oakrender, oaktask,
oakcommon) — no liboakengine dylib, no C ABI, no build.rs link step.
cargo test -p oak-cli stands alone.
Subcommands
Every subcommand of the C++ original is implemented:
oak-cli info <project.ove> <start> <end> <out_dir> project name/sequences/footage
oak-cli render <project.ove> <start_seconds> <end_seconds> <out_dir>
oak-cli probe <mediafile>
oak-cli transcode <input_media> <out> [width] [--format ppm|mp4]
Argument validation is faithful to the C++ (invalid start seconds,
invalid width, unknown --format … all exit 64). The output formatters
(src/fmt.rs) reproduce the C++ printf output byte for byte and are
golden-tested against the output captured from the C++ binary on the test
fixtures (tests/project_with_footage.ove, tests/demo.mp4); the PPM and
WAV writers (src/ppm.rs, src/wav.rs) are the exact ports of the C++
write_ppm/write_wav and are unit-tested.
Layout
src/
main.rs clap surface, --help/-h + unknown-command handling, dispatch
engine.rs module-native assembly layer (M14 R2): project load/create,
footage probe, sequence + clip assembly, montage resolution,
ticket rendering, synchronous export
fmt.rs golden output formatters (info/probe)
ppm.rs P6 PPM writer (f32/u8 frames)
wav.rs PCM s16 WAV writer (interleaved float samples)
cmd/ per-subcommand validation + module-crate calls
tests/cli.rs binary-level tests (exit codes, messages, usage errors)
