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 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.

enricobuehler 70536b464a fix(host/windows): NVENC capture on real GPU + HOME-less config dir
Validated live on an RTX 4090 (Windows 11) host streaming to the Rust
reference client over the LAN: SudoVDA virtual display → DXGI Desktop
Duplication (D3D11 zero-copy) → NVENC HEVC → punktfunk/1. 720p60 and
1080p60 both clean (181 / 177 frames, 0 mismatched, p50 1.6 / 3.45 ms
cross-machine), coexisting with Apollo. Two real-hardware bugs the
GPU-less VM couldn't surface:

- DXGI capturer: the SudoVDA virtual monitor's DXGI output is enumerated
  under the GPU that *renders* it (the 4090, LUID 0x15df6), NOT under the
  SudoVDA "adapter" LUID SudoVDA reports (0x23276). Restricting the output
  search to that LUID found nothing → "adapter has no output named
  \\.\DISPLAYn". Now search ALL adapters for the GDI name, bind the D3D11
  device to whichever adapter exposes it (NVENC then shares that device),
  with a settle-retry (the output appears a beat after display creation)
  and topology logging.

- native_pairing / apps: keyed config paths off raw $HOME, which a Windows
  service/scheduled-task context doesn't set → "HOME unset" hard-fail at
  m3-host startup. Route both through gamestream::config_dir(), which falls
  back to %APPDATA% on Windows (cert/paired/apps now under AppData\Roaming).

clippy -D warnings + build green on x86_64-pc-windows-msvc (default and
--features nvenc) and Linux (78/78 tests).

enricobuehler 73b33d4129 feat(pairing): delegated approval (§8b-1) — approve an unpaired device from the console
An identified-but-unpaired device that knocks on a pairing-required host is now
held as a pending request the operator approves from the web console — pairing it
with no PIN fetched out of band — instead of a flat reject.

- core: Hello gains an optional trailing device name (len u8 || UTF-8, ≤64,
  same trailing-back-compat pattern as compositor/gamepad/bitrate). client-rs
  --name sends it; the connector sends None (fingerprint-derived label).
- native_pairing: in-memory pending queue (note_pending dedups by fingerprint,
  evicts the least-recently-active past a 32 cap, 10-min TTL); approve_pending
  pins the fingerprint, deny drops it. Names are sanitized (strip control/ANSI/
  bidi — untrusted wire input); add()/remove() roll back in-memory on a persist
  failure; pairing clears any stale pending knock.
- m3: the require_pairing gate records the knock (sanitized label) before
  rejecting; anonymous (certless) clients record nothing.
- mgmt: GET /native/pending, POST /native/pending/{id}/approve (optional {name})
  and /deny; OpenAPI + tests; docs/api/openapi.json regenerated.
- web: a "Waiting for approval" section on the Pairing page (live-poll, Approve/
  Deny, error-surfaced via QueryState); en+de strings.
- Also completes an in-progress NativeClient Sync refactor (receivers behind
  per-plane mutexes) that was left half-applied in the tree.

Adversarially reviewed (4 lenses + 3-vote verify); the confirmed findings are
fixed here. Validated live on the GNOME box: knock (with a wire name, and a
malicious ANSI/bidi name that got neutralized) → pending → approve → the same
identity streams real video. Full workspace tests + clippy + fmt green; web tsc
clean. Roadmap §8b-1 marked done; §8b-2 (peer-push approval) is the client
follow-up. See docs-site pairing page.

enricobuehler d1c9f68b6b refactor(native-pairing): extract shared on-demand arming state
Groundwork for web-UI-driven native (punktfunk/1) pairing. Replaces m3's fixed
startup PIN + local paired store with a shared `NativePairing` (new module):
arm-on-demand with a fresh, time-limited PIN (`arm(ttl)`), `current_pin()` read
per ceremony so a lapsed window stops pairing, plus the trust store (list/add/
remove/is_paired) and a `status()` snapshot. The management API (next commit) and
the QUIC accept loop share one handle. CLI `--allow-pairing`/`--require-pairing`
still arm at startup (no expiry, PIN logged) — back-compat. m3 pairing ceremony +
gate and the C-ABI roundtrip stay green; new unit tests for arm/expire/pair.
