Ground-up low-latency streaming stack per docs/implementation-plan.md. M1 is
complete and tested; Linux host backends are cfg-gated stubs to be filled in on
real hardware (M0/M2).
lumen-core (built + tested on macOS/aarch64 — 21 tests):
- fec: ErasureCoder over GF(2^8) (reed-solomon-erasure, Moonlight-compatible)
and GF(2^16) Leopard-RS (reed-solomon-simd, the >1 Gbps wall-breaker); proptested
- packet: zero-copy #[repr(C)] framing, multi-block, FEC-aware reassembly
- crypto: AES-128-GCM with per-direction nonce salts + sequence-as-AAD
- session: host submit / client poll hot paths + input; loopback & UDP transports
- abi: opaque handles, versioned LumenConfig, panic guards; cbindgen-generated header
- acceptance: Rust loopback+proptest and a C harness that links the staticlib
Scaffold (compiles green on all platforms): lumen-host (vdisplay/capture/encode/
inject/web/pipeline seams under cfg(linux)), lumen-client-rs, tools/{loss-harness,
latency-probe}, Apple/Android client stubs, Gitea CI, docs.
Hardened against a multi-agent adversarial review (13 verified findings fixed,
regression-tested): reassembler memory-DoS bounds + block-consistency validation,
GCM nonce-reuse direction separation, ABI struct_size guard + range checks, FEC
shard-length guards, shard_payload datagram bound, key zeroization + Debug redaction.

# lumen Android client (later)
|
|
|
|
Kotlin UI + MediaCodec (decode) + a thin JNI layer over the `lumen-core` C ABI.
|
|
|
|
## Wiring
|
|
|
|
1. Build the core as a shared library per Android ABI:
|
|
```sh
|
|
rustup target add aarch64-linux-android armv7-linux-androideabi x86_64-linux-android
|
|
cargo build -p lumen-core --release --target aarch64-linux-android # liblumen_core.so
|
|
```
|
|
(Use `cargo-ndk` to handle the NDK toolchain/linker.)
|
|
2. JNI shim: small C/Rust glue mapping `lumen_*` to Kotlin `external fun`s, bundling
|
|
`liblumen_core.so` into the APK's `jniLibs/`.
|
|
3. Kotlin: client `LumenSession` → `lumen_client_poll_frame` on a decode thread → feed
|
|
`MediaCodec` → render to a `SurfaceView` aligned to the display refresh.
|
|
|
|
## Status
|
|
|
|
Placeholder — scheduled after the Apple client (M5).
