enricobuehlerandClaude Fable 5 c767a904d2 feat(android): the decode stage answers where its time goes, HUD on or off
P3 decode science: every AU is stamped as its last piece enters the codec, so
the decode stage splits into feed (received→queued: hand-off + input-slot wait)
and codec (queued→decoded: the decoder alone — a slice head start would show
here). The split + an always-on capture→decoded e2e ride the 1 Hz pf-present
line, so a wireless HUD-off A/B reads everything from logcat; the HUD equation
gains the split (indices 30/31), the skipped counter tells benign newest-wins
pacing from parked-AU overflow (32), and a −2-refresh Apple-HUD-equivalent twin
makes iPhone comparisons honest (Apple shaves its OS floor; Android shows raw).

Connect now logs the per-mime decoder picks + FEATURE_PartialFrame verdicts
(tag pf.caps) — on the NP3 all three c2.qti low-latency decoders say no, so
parts delivery never arms and P2d is inert there; a debug.punktfunk.force_parts
sysprop overrides the probe for the on-glass question the API cannot answer.
Forced on glass: c2.qti accepts PARTIAL_FRAME pieces without erroring but only
assembles them — codec time unchanged, so the overlap is dead on SM8735 either
way.

enricobuehlerandClaude Fable 5 253e0bbe7c feat(android): the mic has an off switch you can reach mid-stream
Wave 1 gave the Android client a mic worth using. It gave it no way to stop
talking: leaving the stream, or digging through Settings to turn the whole
feature off, were the only ways to stop the room being heard. Now a tap (or
Select + Y on a pad) mutes it, and the screen says so while it lasts.

How muting gates the capture, and why that way. The AAudio input stream is
never stopped: a stop/start would re-run the input-preset fallback ladder and
re-prime the buffers on every toggle — hundreds of milliseconds, and possibly
a landing on a different rung, silently losing the HAL echo canceller wave 1
went to some trouble to get. Instead the encode loop reads an AtomicBool per
10 ms frame and, while it is set, drains the frame out of its ring and drops
it there — the last point before it would have become an Opus packet. Nothing
is encoded, nothing is sent, and the realtime capture callback is untouched,
so its allocation-free discipline and the queue policy stay exactly as wave 1
verified them. A toggle costs one atomic store and takes effect on the next
10 ms boundary.

The frame counter keeps advancing across a mute, because it numbers the
captured 10 ms TIMELINE rather than the datagrams. The gap the host then sees
is exactly the audio that never came: its de-jitter conceals at most a few
frames of it before the pump's 600 ms stale-gap flush resets the chain
outright, which is the right reading of a mute. Encoding silence instead
would have kept a pointless uplink and a host-side ring alive for its whole
duration.

Mute is per session and nothing is persisted — a new stream always starts
unmuted, and no new setting exists. The flag lives on the session handle
rather than on the capture, so the mic stop/start a surface recreate performs
brings the user's choice back with it, with no window in which the fresh
capture could send an unmuted frame.

The control is offered on the evidence that a capture is actually running
(nativeMicActive), not on the setting: with the mic disabled, RECORD_AUDIO
denied, or every AAudio input rung refused, there is nothing on screen to
lie about. On touch it is a pill in the corner the stats HUD doesn't use —
the one in-stream control, so it sits above the gesture layer to take its own
taps — dim while live, a red "Muted" badge while it isn't. On TV that badge
is the indicator alone: Select + Y is the control there, and a focusable
button would fight the game for the D-pad. Y is deliberately not one of the
exit chord's buttons, so neither chord can be reached through the other.

One honest consequence of keeping the stream open: the platform's recording
indicator stays lit while muted, because the mic really is still open. What
stops is the encode and the send.

enricobuehlerandClaude Fable 5 a681de7e5c feat(android): the mic goes through the echo canceller, and the host stops hearing itself
The capture stream opened under AAudio's default VoiceRecognition input
preset, which deliberately bypasses the HAL's acoustic echo canceller —
so a phone playing the game audio out of its own speaker fed that audio
straight back to the host. Two layers fix it, both behind a new "Echo
cancellation" setting (default ON, next to the Microphone toggle in the
touch and console settings, per-profile like every tier-P setting):

- Native: the mic opens under the VoiceCommunication preset (HAL AEC/NS
  on the capture path) and allocates an audio session id. The open
  ladder is Exclusive+voice → Shared+voice → Exclusive → Shared — some
  HALs refuse the preset or a session id outright, and a mic without
  echo cancellation still beats no mic; the last rungs are exactly the
  preset-less open this always did.

- Kotlin backstop: nativeStartMic now returns the allocated session id
  (0 = none), and StreamScreen hangs the Java AcousticEchoCanceler +
  NoiseSuppressor off it (guarded by isAvailable), releasing them on
  every mic-stop path — the surface teardown and the final dispose — so
  a surface recreate re-attaches instead of leaking effect engines.

The playback stream is untouched: retagging it voice/communication
would route it through the phone-call chain and regress quality.

enricobuehlerandClaude Fable 5 984f7be896 fix(android): the presenter paces to the panel's real grid, not the app's down-rated vsync
On-glass (A024, 120 Hz panel, 120 fps session) the first presenter build
released only 60/s and the HUD display term hit 40 ms. Root cause, in two
layers: Android down-rates a game-category uid's choreographer stream to
60 Hz (frame-rate categories / game default frame rate), and under that
override Display.getRefreshRate REPORTS THE OVERRIDE — so the presenter's
panel grid read 16.67 ms on an 8.33 ms panel and the subdivision became a
no-op, pacing the video at half rate and dropping every other frame.

Three-part fix, verified live on the same device:
- Kotlin passes the panel rate from the supported-modes TABLE
  (MainActivity.streamPanelFps — the mode list is not override-filtered)
  instead of display.refreshRate, and votes the app's render rate up via
  View.requestedFrameRate = streamHz (API 35+) while streaming.
- The native vsync clock LEARNS the panel period from observed timeline
  spacing (downward-only: the finest spacing SurfaceFlinger ever reports is
  the true grid) and next_target subdivides the reported timeline onto it —
  full-rate on down-rated devices, a no-op where callbacks match the panel.
- OnFrameRendered display/latch samples get the e2e clamp (0..10 s): a
  vendor's first callbacks can carry a garbage system_nano (observed: an
  epoch-sized latch max) that would poison every max it lands in.

pf.present gained panelMs next to vsyncMs, and a one-shot cadence
diagnostic logs Δ/timelines/spacing/panel on the third tick.

After: released=120 displays=120 paced=0, pace p50 <1 ms, latch p50 ~16 ms
idle / ~22 ms under game load (2 refresh intervals at 8.33 — the same
composited-pipeline law the Apple client measured), HUD display ~17-26 ms
vs 40 before.

enricobuehlerandClaude Fable 5 e08fd91cd1 feat(android): a timeline presenter — frames reach glass on the panel's schedule, not decode's
The Android port of the Apple client's stage-4 deadline discipline, closing
the side-by-side feel gap (both clients 120 Hz; Android released decoded
buffers the instant they appeared, with zero vsync awareness — the latch
phase inherited every network+decode jitter and bursts queued behind the
display).

The presenter (async loop only; the sync loop stays the untouched escape
hatch behind the Low-latency toggle):

- decode/vsync.rs: an AChoreographer thread (dlsym'd like the other
  above-floor symbols) publishing the panel's vsync grid + frame timelines
  (postVsyncCallback, API 33; postFrameCallback64 fallback on 31/32) and
  ticking the decode loop's event channel. Started lazily on the first
  decoded frame.
- decode/presenter.rs: a newest-wins slot (Lowest latency, default) or a
  1-3 frame smoothing FIFO with preroll/underflow re-arm (Smoothness) between
  decode and release; a glass budget of exactly ONE undisplayed release in
  flight, reopened at the target timeline's DEADLINE (SurfaceFlinger's latch
  — reopening at present time would halve the sustainable rate) with a 100 ms
  stale force-open backstop; the release itself via
  releaseOutputBufferAtTime(expectedPresent) so the latch phase is
  deterministic. debug.punktfunk.presenter=arrival sysprop restores the
  legacy path for a rebuild-free on-device A/B.
- Metrics: DisplayTracker is now always-on and carries the release stamp, so
  the display stage splits into pace (decoded→release) + latch
  (release→displayed); a 1 Hz pf.present logcat line (released/displays/
  paced/noBudget/forced/qDry + pace/latch p50/max + measured vsync) makes a
  HUD-off wireless A/B readable; nativeVideoStats grows to 30 doubles
  (26=paceP50, 27=latchP50, 28=presents, 29=presenterActive; 0-25 frozen)
  and the DETAILED HUD prints the split + presents.
- Intent parity: present_priority/smooth_buffer — the Apple client's
  stored values and labels — as globals, profile-overlay fields (round-trip
  + scope markers), and Settings pickers under Decoding; threaded through
  nativeStartVideo into the presenter config.

Verified: cargo ndk check/clippy clean for arm64 (the two type_complexity
warnings are pre-existing audio/mic ones), armv7 via the kit gradle task,
host cargo check clean, rustfmt clean, gradle :app/:kit unit tests all pass.
On-device before/after on the Nothing Phone 3 still owed.

enricobuehlerandClaude Fable 5 87b6fa8813 feat(android): the panel is pinned to the stream's refresh, and touch skips the vsync batch
Three quick latency wins for phones, ahead of the presenter rebuild:

- setStreamDisplayMode: the window-level preferredDisplayModeId is pinned to
  the stream's refresh (exact rate, else the smallest integer multiple, else
  the highest available) for the session. The surface-level frame-rate hint
  alone is advisory and some OEM refresh governors (Nothing OS's LTPO logic
  among them) ignore it for third-party apps — leaving a 120 Hz session
  presenting on a 60/90 Hz panel. nativeVideoSize gained a trailing
  refreshHz element for this (old readers index only 0/1). TV keeps the
  native HDMI mode switch instead.
- The surface hint itself now passes compatibility = FIXED_SOURCE on every
  form factor: the stream is fixed-rate video the client cannot re-pace;
  DEFAULT invited governors to not switch.
- requestUnbufferedDispatch(SOURCE_CLASS_POINTER) on the hosting view while
  streaming: touch/pointer events were vsync-batched — up to a frame of
  input latency the stream shouldn't pay.
- The HUD polls the panel's live refresh each second and flags '⚠ panel N Hz'
  when it sits below the stream rate, so an unpinned panel is visible instead
  of reading as inexplicable judder. Stale nativeStartVideo kdoc (low-latency
  'off, the default') corrected — it defaults ON under low_latency_mode_v2.

MediaCodec scales whatever it decodes to fill the Surface it renders into,
and the Surface filled the screen — so a stream whose resolution didn't
match the panel's aspect came out stretched. Nothing downstream of the
Surface can correct that; the Surface itself has to carry the aspect.

Size the video to the negotiated mode's ratio, centred, with the remainder
black. The mode is known from the handshake before the first frame arrives,
via a new `nativeVideoSize` (the same `client.mode()` the HUD already
reports as `w×h@hz`); an older native lib returning nothing falls back to
filling, exactly as before.

Input follows the picture. Direct-pointer touch, multi-touch passthrough
and the pen lane all map positions against the size of the node they sit
on, so the gesture layer moves onto the same rect as the video and all
three stay correct by construction instead of each needing an offset
threaded through it. The physical-mouse path can't work that way — its
events arrive from the activity in WINDOW coordinates — so it now measures
against the SurfaceView's rect on screen, subtracting the letterbox origin
and clamping into the picture: a pointer out on a bar has no host position
of its own, and the edge is the honest answer for it.

One deliberate consequence: trackpad swipes that START inside a letterbox
bar no longer register. Trackpad input is relative and could have kept the
whole panel, but one rule — input lands on the picture — beats a mode-
dependent input surface, and the pen lane rides inside trackpad mode too.

enricobuehlerandClaude Fable 5 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.

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.

enricobuehlerandClaude Opus 4.8 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.

enricobuehlerandClaude Fable 5 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.

enricobuehlerandClaude Fable 5 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.

enricobuehlerandClaude Fable 5 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.
