enricobuehler	ddb93c533c	fix(core,android): networking-audit small follow-ups — bounds, oversized AUs, probe flag ... Networking-audit deferred plan §6: - 6.1 client reassembler ceiling derived from the negotiated rate: Welcome::session_config (client role) now sets max_frame_bytes to clamp(4 × bitrate_kbps×125 / refresh_hz, 8 MiB, 64 MiB) instead of the blanket 64 MiB p1_defaults bound — the hostile-header memory ceiling was ~10× larger than any real access unit. Local only (the host never reassembles video; the wire is self-describing); a bitrate-0 (older) host keeps the old bound. Unit-tested floor/derived/host/old-host cases. - 6.2 ProbeState.active is cleared when the host's ProbeResult lands, so the pump stops mirroring receive counters once the burst is over. - 6.3 Android: an AU larger than the codec input buffer is DROPPED with a recovery-keyframe request and a counter, on both the sync (feed) and async (feed_ready) paths — a truncated AU is corrupt input the decoder chews on silently, poisoning the reference chain until the next IDR. The async path recycles the never-queued input slot; the sync path returns the dequeued slot with zero valid bytes. - 6.4 bounded uplink channels: mic_tx at 64 (~320 ms of 5 ms frames; overflow sheds the fresh frame with a debug log — a tokio mpsc can't shed from the head, and past 320 ms of backlog the mic is broken either way; the bound is about memory) and ctrl_tx at 32 (sparse requests; a full queue means a wedged control task, reported as Closed). input_tx stays unbounded per the plan: keyboard/mouse events must never silently drop, and gamepad state is snapshot-healed. - 6.5 (wire version byte says P1 while streaming Gf16): record-only, resolves with the P2 packet revision. include/punktfunk_core.h: cbindgen re-emitted in the new module order after the quic/ split (item 3) — no semantic change beyond the reorder. cargo ndk check (arm64-v8a), workspace clippy, core+host tests green.

enricobuehler	d4467a44e2	feat(core): mid-stream clock re-sync — live offset survives wall-clock steps and drift ... Networking-audit deferred plan §2. The host↔client offset was measured once at connect; an NTP step or slow drift silently corrupted the clock-based jump-to-live signal, the ABR one-way-delay signal, and every latency stat — 4a3b1ae2's disarm backstop stopped the IDR storm but lost the detector for the session. Now the client re-estimates mid-stream and recovers it. - quic: ClockResync — the connect-time 8-round probe/echo estimate as a select!-driven state machine (rounds matched by echoed t1, stale batches ignored), plus accept_resync (batch min-RTT ≤ max(2 ms, 1.5× connect RTT) so a congested window can never bias the offset). No wire change: the host has always answered ClockProbe at any time on the control stream. - client: the offset lives in an Arc<AtomicI64> seeded at connect; the control task re-probes every 60 s and immediately after the pump's FIRST no-op clock flush (the "clock stepped under me" signal, sent on the next report tick). On apply: store, reset stale_frames/noop_clock_flushes, re-arm the clock detector if a step had disarmed it. The disarm heuristic stays as the final backstop. Public NativeClient::clock_offset_ns keeps the connect-time value (ABI untouched); new clock_offset_now_ns() / clock_offset_shared() expose the live value. - consumers migrated to the live offset: pf-client-core session stats, the pf-presenter e2e stamp, Windows session/render, Android feeder/drain/ DisplayTracker (the tracker holds the shared handle, not the client, so the leaked render-callback refcount can't pin the session). - probe: --clock-resync runs a second full handshake mid-connection and asserts a sane, consistent estimate. Live against the local canary host: offsets 8646/2139 ns, disagreement 6 µs, 8/8 rounds — OK. Unit tests cover the round collection, stale-echo rejection, batch restart, min-RTT selection, and the acceptance guard. cargo ndk check green. Remaining manual validation: `sudo date -s "+2 sec"` on a live streaming client → expect one no-op flush, a re-sync, re-armed detector, no IDR pulse.

enricobuehler	f5e5297a2a	style: cargo fmt — settle comment/assert layout the last two fixes left unformatted ... `cargo fmt --all --check` on main flags decode.rs (android dlsym fix), probe/main.rs (0600 key fix), and session.rs (anti-replay tests). The probe one is restructured rather than machine-formatted: rustfmt wanted the key- permissions comment gutter-aligned to the trailing `// the certificate is public` comment, so fold both into one block comment above the write instead.

enricobuehler	8fa12167af	fix(android): client loads again on Android < 13 — dlsym the API-33 render callback ... 0.9.0's HUD display stage hard-linked AMediaCodec_setOnFrameRenderedCallback via ndk-sys believing it API 26; the symbol is API 33 ("Available since Android T"). A cdylib links fine with the dangling import, so it only exploded at System.loadLibrary on every pre-13 device: UnsatisfiedLinkError, then every NativeBridge touch throws NoClassDefFoundError — surfacing as "Identity unavailable: io.unom.punktfunk.kit.NativeBridge", a dead pair button, and no discovery (reported on a Y700 / Android 12; 13+ devices unaffected). - decode::install_render_callback now dlsym-resolves the entry point from libmediandk.so, mirroring try_set_frame_rate; on API < 33 the HUD simply has no display stage (the pre-0.9.0 behaviour) and the .so loads. - New scripts/ci/check-android-jni-imports.sh, wired as checkJniImports* gradle tasks the APK build depends on: fails the build if libpunktfunk_android.so imports any symbol absent from the NDK's API-28 stubs — `--platform 28` never enforced this (cdylib links permit undefined symbols), despite the old comment's claim. Verified: 3 ABIs clean at the 28 floor, and the check flags the known API-28 symbols when pointed at a 27 floor. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 10:06:31 +02:00
enricobuehler	13d1aa5738	feat(clients/android): OnFrameRendered display stage — HUD headline becomes capture→displayed ... The long-deferred Android display stage (design/stats-unification.md; plan 4.1 of design/client-parity-and-network-resilience.md): AMediaCodec_setOnFrameRenderedCallback (API 26, under the minSdk-28 floor ⇒ hard-linked via ndk-sys) reports SurfaceFlinger's per-frame render timestamp, giving the HUD the spec's `display` = decoded→displayed term and the directly-measured capture→displayed end-to-end headline on both decode loops. Falls back per spec to the v1 capture→decoded endpoint on any window without render callbacks (the platform may drop them under load), and to it permanently if registration is refused. - The render timestamp arrives on CLOCK_MONOTONIC; it's re-based onto CLOCK_REALTIME against monotonic-now at callback time, which also cancels the (batchable) callback delivery lag. - The `ndk` crate exposes neither the callback nor the codec pointer needed to bind it raw, so the workspace pins `ndk` 0.9.0 to a vendored copy (clients/android/native/ vendor/ndk) whose ONLY change makes MediaCodec::as_ptr public — the "as_ptr patch". Workspace-excluded so host builds never compile it; drop when upstream exposes either. - nativeVideoStats grows to 26 doubles (22–25: dispValid, displayP50, e2eDispP50/P95; 0–21 unchanged for older readers); StatsOverlay moves headline endpoint + equation together so the equation always tiles the headline interval. Verified: host cargo check/test/clippy, aarch64-linux-android check/clippy, Kotlin app+kit+tests compile, roborazzi HUD render shows the full 4-term equation. Device verification rides plan 4.2's phone A/B. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-09 11:35:16 +02:00
enricobuehler	4c9c7e606e	feat(android): tiered stats HUD + windowed lost/skipped/FEC counters ... Stats overlay verbosity tiers (Off/Compact/Normal/Detailed, 3-finger tap cycles live, old Boolean pref migrated) and the unified-spec line-4 reliability counters: lost/FEC windowed from the connector's cumulative totals, skipped from the client's own newest-wins drops. Adds the fec_recovered_shards accessor to NativeClient, mirrored from the data-plane pump like frames_dropped. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-08 12:29:56 +02:00
enricobuehler	04302075b5	feat(android): promote the low-latency pipeline to default ... The async decode loop (burst-feed + present-newest-per-vsync, the Apple client's discipline) plus the per-SoC tuning was gated behind an experimental, default-off toggle after the 5dc24a0 overhaul regressed on some phones. That regression was the receive-side latency ratchet the async loop fed — a standing queue that only grew — now fixed in the shared core (FrameChannel jumps to live instead of accumulating it), so the fast pipeline is the default again. Default the master toggle on via a fresh pref key (low_latency_mode_v2), mirroring the migration da376b31 used to flip it off: a new key re-defaults every install — including ones persisted off under the old key — to on, so the promotion reaches users who had saved settings, not just fresh installs. Both stale keys are abandoned unread. Toggle-off still restores the original synchronous decode pipeline byte-for-byte as a per-device escape hatch. Drop "(experimental)" from the settings labels and fix the now-stale default-off wording in the native + Kotlin docs. No decode-path routing change — run_async is reached simply because the toggle now defaults on. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-07 16:18:40 +00:00
enricobuehler	da376b3122	fix(android): gate the latency overhaul behind an experimental toggle, default off ... The 5dc24a0 low-latency overhaul regressed badly on some phones. Every piece of it — decoder ranking, per-SoC vendor keys, the async decode loop, pipeline thread boosts, the ADPF max-performance bias, game-tagged AAudio, DSCP marking, the Wi-Fi low-latency lock, HDMI ALLM and the forced TV mode switch — now rides the "Low-latency mode (experimental)" toggle, default OFF. Off restores the pre-overhaul pipeline byte-for-byte: the sync poll loop, the platform-default decoder, and the original format keys (standard low-latency + blind Qualcomm twin + priority=0 + operating-rate=MAX together). - New pref key (low_latency_mode_experimental): the old key shipped default-ON, so any install that ever saved settings persisted true — flipping the default under the old key would leave exactly the regressed devices stuck on. - DSCP is applied at socket creation, so the toggle reaches the transport via NativeBridge.nativeSetLowLatencyMode → transport::set_dscp_default, called in the connect choke point before nativeConnect; the core DSCP default reverts to off everywhere. - nativeStartAudio(handle, lowLatencyMode) gates AAudio usage=Game. - VideoDecoders.pickDecoder now skips `.secure` decoder twins and decoders that require FEATURE_SecurePlayback: they need a secure surface, and a secure twin could out-score its plain sibling (only it advertising FEATURE_LowLatency), which black-screens a clear stream.

enricobuehler	5dc24a069f	perf(android): low-latency decode overhaul — vendor keys, async loop, system tuning ... Close the latency gap on the Android client with per-SoC decoder tuning, an event-driven decode loop, and full system integration. - Decoder selection: rank MediaCodecList decoders in Kotlin (hardware/vendor preferred, software avoided, FEATURE_LowLatency probed) and create the chosen one by name. Per-SoC low-latency keys gated on the codec-name prefix: Qualcomm picture-order + low-latency, Exynos (also Google Tensor), Amlogic, HiSilicon; MediaTek vdec-lowlatency set unconditionally. operating-rate = MAX (Qualcomm) vs priority = 0 (else) are mutually exclusive. NVIDIA/Rockchip/Realtek have no vendor key — covered by ranking + the standard low-latency key. - Async decode loop: AMediaCodec async-notify replaces the poll loop, presenting a decoded frame the instant it is ready instead of waiting out a poll interval. Behind USE_ASYNC_DECODE with the synchronous loop kept for A/B during bring-up. - System integration: Wi-Fi FULL_LOW_LATENCY lock and HDMI ALLM (setPreferMinimalPostProcessing) for the stream's lifetime; game_mode_config.xml opting out of OEM downscaling / FPS overrides. - Pipeline: boost the data-plane pump + audio thread priorities, AAudio usage=Game, DSCP marking on by default on Android, ADPF setPreferPowerEfficiency(false), and setFrameRateWithChangeStrategy(ALWAYS) to force the HDMI mode switch on TV. - lowLatencyMode master toggle (default on) as the escape hatch; the stats HUD now shows the resolved decoder name.

enricobuehler	3775a39e70	feat(android): console UI, wake-on-LAN wait-until-up, host edit + TV/tablet polish ... Bring the Android client to parity with Apple's gamepad experience and finish Wake-on-LAN. - Console/gamepad home: host carousel, aurora chrome, mTLS game-library coverflow, and an input-aware legend that switches between gamepad face buttons and a TV-remote select-ring + arrows based on the last-used input. - Wake-on-LAN: the fire-and-forget send is upgraded to wait-until-up (WakeController/WakeOverlay: resend + mDNS poll, 90s timeout, cancel/retry, fingerprint-matched so a host that cold-boots onto a new DHCP IP still connects), plus host edit (touch dialog + console form) with an auto-filled MAC. - Android TV: brand banner (android:banner), density-aware console scaling, D-pad/ remote nav (Up = Settings, Down or the pad Select button = host Options), emergency stream-exit chord, and 120Hz console refresh. - Touch UI: settings split into subpages with a tablet NavigationRail, axis-aware tab animation (horizontal on phones, vertical on the tablet rail), animated settings navigation, and a licenses screen with a back button + the real workspace version (read from Cargo.toml). - Vector Lock/controller icons (no emoji); bundled Geist font.

enricobuehler	d6dbce1dcc	feat(clients): host/network split in every stats HUD (stats phase 2, client side) ... Consumes the 0xCF host-timing plane (99cb8dd) on all four GUI clients: each keeps a bounded pending ring of receipt samples keyed by pts, matches the host's per-AU capture→sent reports against it, and the HUD equation becomes = host 3.1 + network 6.7 + decode 2.1 + display 2.3 falling back to the combined `= host+network …` term whenever no timing matched the window (old host / datagram loss) — same total, one split fewer, never a misleading zero. Apple additionally gains the split as the only equation line under the stage-1 fallback presenter (receipt is presenter-independent), a `nextHostTiming` wrapper with its own plane lock, and a unit-tested `HostNetworkSplitter`; Android extends the JNI stats array 16→18 doubles (0–15 unchanged); Windows/Linux thread the split through `Stats` into the HUD and the headless/debug logs. Docs updated: design/stats-unification.md Phase 2 → implemented (wire format, fallback semantics), and the docs-site matrix's Sunshine "Host processing latency" row is now a direct match (ours includes the paced send; avg vs p50). Verified here: linux client clippy -D warnings green on the live tree, windows stub check + hand-verified diff, android cargo-ndk arm64 check green, apple loopback test extended (needs the rebuilt xcframework + swift test on the mac). On-glass: pending on all platforms. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-03 21:31:49 +00:00
enricobuehler	83460cd2c0	feat(clients): unified stats vocabulary across every client + Moonlight comparison docs ... One stat model everywhere (design/stats-unification.md): four measurement points (capture/received/decoded/displayed), three stages that tile the interval exactly, and a HUD that shows the addition explicitly — end-to-end 14.2 ms p50 · 19.8 p95 · capture→on-glass = host+network 9.8 + decode 2.1 + display 2.3 replacing each client's ad-hoc mix of overlapping absolutes (the Apple HUD's three arrow lines that looked sequential but weren't), mean-vs-median decode times (Windows/Linux), missing same-host-clock flags (Windows/Linux), and three different names for the same capture→received measurement (probe's "reassembled", Apple/Android's "client", Windows/Linux's post-decode "lat"). Per client: Apple threads receivedNs through the VT decode via the frame refcon bit pattern so the decode stage exists at all (stage-1 fallback honestly degrades to a capture→received headline); Windows carries FrameTimes through the existing frame channel to the render thread and adds e2e p50/p95 post-Present; Linux stamps received at AU pop and rides decoded_ns on DecodedFrame to the paintable-set site; Android pairs receipt stamps with MediaCodec output buffers via the codec's pts round-trip (JNI stats array 14→16 doubles, indexes 0-13 unchanged). fps now uniformly counts received AUs; lost/(received+lost) per window, hidden at zero. docs-site gains "Understanding the Stats Overlay": what each line means, why the equation only approximately sums (percentiles), and a line-by-line Moonlight/Sunshine matrix — including that Moonlight has no end-to-end number and its "network latency" is an ENet control RTT, so punktfunk's headline must not be compared against any single Moonlight line. Verified here: linux client + probe + core check/clippy/fmt green, android native cargo-ndk arm64 check green. Pending: Windows CI + on-glass, swift test on the mac, on-device Android.

enricobuehler	495646b676	feat(client/android): Snapdragon latency tuning — ADPF pipeline hints, game mode, max-clock decode ... Three levers to lower and steady decode latency on Snapdragon (Adreno) devices: - ADPF (Adaptive Performance Framework): a new dlsym-resolved hint session (native/src/adpf.rs; API-33+, resolved at runtime so there's no build-time link dependency and libpunktfunk_android.so still loads on API 31/32) tells the CPU governor the video pipeline runs a per-frame real-time workload, so it keeps those threads on fast cores at high clocks. It now covers all three latency-critical threads — the pf-decode feed/drain/present loop, the core data-plane pump (UDP receive + FEC reassembly), and the audio thread — via a new generic hot-thread registry on NativeClient (register_hot_thread / hot_thread_ids; the pump self-registers). The session is built lazily on the first presented frame, since ADPF createSession rejects a set containing any not-yet-live tid. - operating-rate -> Short.MAX ("as fast as possible"): pushes the Qualcomm decoder to run each frame at max clocks instead of merely sustaining the display rate at a power-saving clock that adds per-frame decode latency. - appCategory="game": makes the app eligible for OEM Game Mode / Game Dashboard performance profiles. The core registry is cross-platform (gettid on Linux/Android, a no-op elsewhere) — no Android-specific pollution of the shared core. Host workspace + 64 core tests green; Android arm64-v8a + x86_64 (platform 31) build + clippy clean. On-device Snapdragon validation pending.

enricobuehler	c890de49c9	refactor(android): split session JNI into modules, HUD-gated stats, AAudio open retry ... - native: the 756-line session.rs becomes session/{mod,connect,input,planes}.rs around a SessionHandle (connect lifecycle + trust, input plane shims, plane start/stop + stats drain). - Decode-stats sampling is HUD-gated (nativeSetVideoStatsEnabled): with the overlay hidden the decode thread skips the per-AU clock read + lock; enabling resets the measurement window. - audio: the AAudio open path is a per-sharing-mode try_open closure — the realtime callback state (ring, prime, free-list) is rebuilt per attempt, so a failed exclusive-mode try can't leak state into the shared-mode retry. - Kotlin: ConnectScreen/StreamScreen slimmed by extracting ConnectDialogs, StatsOverlay and TouchInput.

enricobuehler	b357934cb1	feat(clients): codec preference on Windows/Apple/Android clients (Phase 2b) ... Rounds out codec negotiation across the last three clients — each advertises what it can decode, builds its decoder from the resolved Welcome.codec, and exposes a "Video codec" preference picker. **Windows** (Rust, mirrors Linux): `decodable_codecs()` + `ffmpeg_codec_id()`; the D3D11VA and software FFmpeg decoders (and the mid-session D3D11VA→software demotion) open the negotiated codec instead of hardcoding HEVC; settings gain a `codec` field + reactor ComboBox; `--codec` CLI flag. **Apple** (Swift/C-ABI): AnnexB is now codec-aware — a `VideoCodec` enum drives H.264 vs HEVC NAL parsing / parameter-set extraction (`CMVideoFormatDescriptionCreateFromH264ParameterSets` for H.264, no VPS) and AVCC repacking; `PunktfunkConnection` advertises H264|HEVC via `punktfunk_connect_ex7`, reads `resolvedCodec` (`punktfunk_connection_codec`), and threads `videoCodec` into the stage-1/2 pipelines + `VideoDecoder`; SettingsView "Video codec" Picker (auto/HEVC/H.264). AV1 is left out (hosts don't emit it on the native path, and it's not an AnnexB codec). Test call sites updated. **Android** (Kotlin + Rust JNI): the JNI `nativeConnect` gains `preferredCodec`; the native decode loop picks the AMediaCodec MIME (`video/hevc`|`video/avc`) from `connector.codec` and advertises H264|HEVC; Settings `codec` field + Compose dropdown. Core/host/probe/Linux clippy + tests green (unchanged from 2a). Windows/Apple/Android compile on their platform CI (this Linux box can't build them — Windows toolchain / Xcode / the Android NDK's opus-cmake toolchain). All follow the Linux client's validated pattern. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-02 00:29:38 +00:00
enricobuehler	4ddd65d732	feat(clients): HDR Steps 2-3 — apply mastering metadata + display capability-gate ... Continues docs/hdr-pipeline-plan.md. Steps 0/1 + Step 2 (Windows/Android) already landed in ffae2a3; this is Step 2 (Apple) + Step 3 (all clients). Client-only — no core/host/ABI change (the 0xCE/next_hdr_meta/color_info surfaces shipped in Step 0). Step 2 — clients APPLY the host's HDR metadata (each remaps from the wire form: ST.2086 G,B,R order, mastering luminance in 0.0001 cd/m2): - Apple: connect via punktfunk_connect_ex5 (resurrects the previously-dead HDR pipeline); nextHdrMeta/colorInfo wrappers + HdrMeta SEI-blob builders; the pump drains nextHdrMeta -> VideoDecoder.setHdrMeta -> CVBufferSetAttachment of MasteringDisplayColorVolume (24B BE) + ContentLightLevelInfo (4B BE) on each HDR pixel buffer (correct for the itur_2100_PQ layer; CAEDRMetadata avoided as ambiguous there). Step 3 — capability-gate: advertise HDR caps ONLY when the display can present it, so an SDR display gets a proper BT.709 stream instead of PQ it would mis-tone-map; an HDR display self-tone-maps from the Step-1/2 mastering metadata. - Windows: present::display_supports_hdr() (DXGI any IDXGIOutput6 colour space == G2084), ANDed with the user HDR setting in session.rs; logs the SDR drop. - Apple: NSScreen.maximumExtendedDynamicRangeColorComponentValue>1 (macOS) / UIScreen.main.potentialEDRHeadroom>1 (iOS) in SessionModel. - Android: Settings.displaySupportsHdr (Display.getHdrCapabilities HDR10/HDR10+) passed through a new hdr_enabled jboolean on nativeConnect; session.rs gates the caps. Validation: Android native (incl. the jboolean gate) builds + clippy clean via cargo-ndk; fmt clean. Windows (MSVC), Apple (Swift) and the Kotlin side are CI/on-glass validated — not compilable on the Linux dev box. Deferred to the RTX box: mid-session Reconfigure SDR-downgrade on monitor move, and confirming the host emits SDR for an SDR client off an HDR desktop.

enricobuehler	ffae2a31e4	feat: HDR Step-0 colour-metadata transport + security-audit hardening ... Two strands, entangled in punktfunk1.rs, committed together (one builds-green tree). HDR pipeline Step 0 — glass-to-glass colour-metadata transport (docs/hdr-pipeline-plan.md): - Protocol/ABI: ColorInfo on the Welcome + a 0xCE HdrMeta datagram carry the source colour space + HDR10 static mastering metadata (quic.rs, abi.rs connect_ex5 fixing caps=0). - New platform-independent, unit-tested HDR static-metadata helpers (hdr.rs): chromaticities (1/50000), mastering luminance (0.0001 cd/m2), MaxCLL/MaxFALL in HDR10/ST.2086 units. - Capture/encode hooks (capture.rs, encode.rs set_hdr_meta) + Linux client / probe plumbing. Security-audit hardening — top 3 from docs/security-review.md, each adversarially verified: - #1 [HIGH] Secret file permissions. The host key.pem/cert.pem and both trust stores are now written owner-only: 0600 + dir 0700 on Unix (mirrors mgmt_token), best-effort SYSTEM/Administrators/OWNER-only icacls DACL on Windows (%ProgramData% is Users-readable). Closes a local key-disclosure -> host-impersonation gap. New gamestream::{create_private_dir, write_secret_file} + a 0600 regression test. - #2 [HIGH] Native SPAKE2 PIN is single-use. The PIN is consumed the moment the host sends its key-confirmation (which lets the client test its one guess), before reading the proof, so any completed attempt -- right OR wrong -- disarms the window. A wrong PIN isn't observable host-side (the client aborts before sending its proof), so consuming on first attempt is what delivers the documented "one online guess" instead of an unbounded brute-force of the static 4-digit PIN. Test verifies single-use. - #3 [MEDIUM] RTSP packetSize is bounded ([64,2048] in stream_config) and VideoPacketizer::new uses saturating .max(1), killing a PRE-AUTH div-by-zero/underflow panic of the video thread. Tests for {0,15,16,17} + out-of-range rejection. fmt + clippy -D warnings clean; full workspace test suite green (93 host tests).

enricobuehler	1d78c29129	fix(android): DataSpace impls Display not Debug — use {ds} in HDR logs ... ndk's DataSpace derives Copy/PartialEq/Eq and impls Display (no Debug), so the {ds:?} in the HDR dataspace log statements wouldn't compile under cargo-ndk.

enricobuehler	8da8037b35	feat(android): HDR (Main10 / BT.2020 PQ) + fix ndk feature gating ... Mirrors the Apple client's HDR path so the Android client can display HDR from a Windows HDR host: - nativeConnect now advertises VIDEO_CAP_10BIT | VIDEO_CAP_HDR (was 0), so the host upgrades to a Main10 / BT.2020 PQ encode. - decode.rs detects HDR reactively from the decoder's reported output colour (color-transfer ST2084=6 / HLG=7, color-range) -- the AMediaCodec analogue of VideoToolbox's format description on Apple -- and signals the Surface dataspace (Bt2020[Itu]Pq / Bt2020[Itu]Hlg) so the compositor/display switch to HDR. AMediaCodec decodes Main10 from the in-band SPS; no profile override needed. Also fixes the Android build: set_frame_rate (added in e9de730) is gated on the ndk `nativewindow` + `api-level-30` features, which weren't enabled -- so that commit could not compile under cargo-ndk. Enable features = ["media","audio","nativewindow","api-level-31"] (minSdk 31): covers set_frame_rate (api-30), set_buffers_data_space + the DataSpace module (api-28), and ANativeWindow (nativewindow). Verified host-side: fmt --all + clippy --workspace (the caps advertise + JNI surface). The android-gated decode + NDK gating verified against the ndk 0.9 sources; android.yml (cargo-ndk) is the compile gate, and real HDR display needs an HDR device + Windows HDR host.

enricobuehler	e9de730377	feat(android): live stats HUD + low-latency decode tuning ... Stats HUD (mirrors the Apple client): the decode thread accumulates FPS, receive throughput, and capture->client latency (p50/p95, skew-corrected) in Rust (clients/android/native/src/stats.rs); nativeVideoStats drains a snapshot ~1 Hz over JNI as a DoubleArray. StreamScreen renders a Compose overlay (W*H@Hz / fps / Mb/s / latency, + dropped-under-loss), toggled by a Settings switch (persisted, default on) or a 3-finger tap. Performance (decode.rs): - ANativeWindow_setFrameRate(refresh_hz): align display vsync to the stream rate (no 60-in-120 judder); safe since minSdk 31 >= API 30. - Raise the decode thread toward URGENT_DISPLAY (best-effort setpriority) so background work can't preempt it under load. - Codec low-latency hints KEY_PRIORITY=0 (realtime) + KEY_OPERATING_RATE. Verified host-side: cargo build/clippy/fmt --workspace (the ungated stats + JNI accessor). The android-gated decode.rs (NDK) and the Kotlin build only in CI (android.yml: gradle + cargo-ndk) -- APIs verified against crate sources.

enricobuehler	2f2147b093	refactor: drop milestone names + consolidate clients; loss-recovery & rumble fixes ... Two bodies of work in one commit (the rename moved files the fixes also touched). Naming/structure cleanup (pre-launch): - Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host, m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source-> Punktfunk1Options/Punktfunk1Source. - Clients consolidated out of crates/ into clients/: punktfunk-client-rs-> clients/probe (crate punktfunk-probe), client-linux->clients/linux, client-windows->clients/windows, punktfunk-android->clients/android/native (crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI contract is unchanged). crates/ now holds only core + host. - Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site, kept only in docs/implementation-plan.md. docs/m2-plan.md-> docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated. Client loss-recovery (video froze and never recovered after a brief drop): - Export punktfunk_connection_frames_dropped through the C ABI (the core already tracked it for the client keyframe-recovery loop; it was never reachable from the ABI clients). Regenerated punktfunk_core.h. - Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll frames_dropped and request a keyframe when it climbs -- the same loss-driven recovery Linux/Windows already had. Under infinite GOP the decoder silently conceals reference-missing frames, so the decode-error trigger rarely fires. Apple rumble robustness (worked then went spotty -- DualSense + Xbox): - Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio interruption / server reset) and drop the permanent `broken` latch on a transient drive failure; latch only when the controller truly has no haptics. - Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging. Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift. Not runnable on this box (verify in CI): Gitea workflows, gradle/Android, flatpak, Swift/decky.
