enricobuehler	de7b8ac282	feat(android): video decode pipeline — NDK AMediaCodec → SurfaceView ... M4 Android stage 1 (video). Pull HEVC access units from the connector and render them to the SurfaceView entirely in Rust (NDK AMediaCodec → ANativeWindow) — no per-frame JNI, honoring the native-thread hot-path invariant. - crates/punktfunk-android: decode.rs (one-in/one-out AMediaCodec loop; in-band VPS/SPS/PPS so no out-of-band csd; dims from NativeClient::mode). SessionHandle now holds an Arc<NativeClient> + the decode thread; nativeStartVideo/nativeStopVideo. - clients/android: connect screen (host/port) + full-screen SurfaceView stream screen — surfaceCreated -> nativeStartVideo, leaving -> stop + close. Verified live (Android emulator -> m3-host on the LAN box, ABI v2): QUIC handshake, 8-round clock-skew sync, HEVC decoder configured at 1280x720, and the data plane delivered + fed all 299 access units (the punktfunk/1 NAT hole-punch worked through the emulator's SLIRP). Real-pixel render is pending a non-synthetic source: `m3-host --source synthetic` emits dummy transport payloads (not HEVC), so the decoder correctly produces nothing; `--source virtual` (a compositor on the host) is needed to verify decode-to-screen.

enricobuehler	79217eb93d	feat(android): scaffold the native Android client (Rust-heavy JNI bridge) ... Rust-heavy client model (like punktfunk-client-linux): a new cdylib crate crates/punktfunk-android links punktfunk-core and exposes the JNI seam; Kotlin (clients/android) owns only the Android-framework surface. Kotlin can't import the C header the way Swift can, so the bridge is written in Rust to reuse the Linux client's orchestration rather than re-port it. - crates/punktfunk-android: JNI bridge — abiVersion/coreVersion native-link proof + session connect/close handle; plane pumps stubbed for M4 stage 1. - clients/android: Gradle project — :app (Compose) + :kit (Android library with a cargo-ndk Exec task -> jniLibs). AGP 9.2 / Gradle 9.4.1 / Kotlin 2.3.21 / Compose BOM 2026.05.01 / compileSdk 37 / targetSdk 36 / minSdk 31, shipping arm64-v8a + x86_64. Phone + TV (leanback) installable. README rewritten. - .gitea/workflows/android.yml: CI mirroring apple.yml on a Linux runner. - punktfunk-core: switch rcgen to the ring backend so the whole quic tree is aws-lc-free (smaller client .so, cmake-free cross-compile; a win for all targets). Validated on this box: :app:assembleDebug -> APK with both ABIs; emulator first-light renders the bridge linked (core ABI v2) with logcat confirmation; clippy -D warnings + cargo fmt clean; core tests green on the ring backend.

enricobuehler	bfd64ce871	rename: lumen → punktfunk, everywhere ... Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git.

enricobuehler	a913042367	feat: M1 lumen-core (FEC/crypto/packet/session + C ABI) and workspace scaffold ... 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.
