Discovery: replace the flaky per-OEM NsdManager with the same mdns-sd browse
the Linux/Windows clients use, in the Rust core over JNI and polled by Kotlin
(discovery.rs + nativeDiscovery{Start,Poll,Stop}); Kotlin keeps only the Wi-Fi
MulticastLock + permission UX. IPv4-only (the core can't dial a bare/scoped v6
literal); daemon + fold-thread cleanup on every failure path; field
sanitization so a rogue advert can't corrupt the picker snapshot. Discovery
now starts regardless of NEARBY_WIFI_DEVICES (raw multicast only needs the
MulticastLock) — a denial no longer kills it forever. ParseTxtTest replaced by
ParseRecordTest.
Hosts: hide already-saved hosts from the "Discovered" section (match by
fingerprint, else address:port — mirrors the Apple client); add an optional
Name field to the Add-host sheet and a Rename action on saved cards.
Input: touch -> absolute mouse "direct pointing" like the Apple client — the
host cursor follows the finger (new nativeSendPointerAbs -> MouseMoveAbs). Tap
= left click, two-finger tap = right click, two-finger drag = scroll,
tap-then-drag = left-drag, three-finger tap = HUD toggle.
Settings: revert the dropdowns to the stock ExposedDropdownMenuBox look (a
controller-focus UI will come separately); even out the Add-host field gaps.
Docs updated (CLAUDE.md, client READMEs, docs-site status).

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.

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.

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.
