enricobuehler bae8742e48 fix(apple): the library's unreachable message pointed at the wrong layer
It led with `--mgmt-bind 127.0.0.1`, a rare cause, and never mentioned the one
fact that actually explains the symptom: the library rides the management API on
a different port (47990) than the QUIC stream plane (9777), so it can fail while
streaming to the same host works. Field triage of exactly that case spent hours
on the stream path before anyone questioned the port.

Leads with that now, and names browser-testing the port as the fast split between
"unreachable" and anything client-side.

enricobuehler 78a02bc994 fix(apple): ATS blocked the library on every non-RFC1918 host
The game library rides the management REST API over HTTPS (TCP 47990) through
URLSession, authenticated by mTLS and pinned by SHA-256 fingerprint. The app
declared no App Transport Security policy at all, so it ran under default ATS --
which exempts only "local" destinations (.local, unqualified names, RFC1918 and
link-local literals) and applies the full policy everywhere else. The host
certificate is self-signed (and carries no SubjectAltName), so it cannot satisfy
that policy: the library loaded at 192.168.x and failed at the TLS layer on any
other address.

Field-reported against a Tailscale host. 100.64.0.0/10 is CGNAT, not RFC1918, so
the library failed there while streaming to the very same address worked -- the
QUIC stream plane is raw UDP and never enters the URL loading system. A WireGuard
peer or a public-IP host breaks identically.

Declares NSAllowsArbitraryLoads, which must stay the dict's only key: iOS 10+ and
macOS 10.12+ ignore it whenever a more granular ATS key sits alongside it. Trust
is unchanged -- LibraryTLSDelegate still pins the host by fingerprint and hands
every other origin (cover-art CDNs) to full system trust evaluation.

The Apple half of the A/V sync overhaul; the Rust half is 12a53183 and this
mirrors its policy rather than re-deriving one.

The host stamps `pts_ns` on every audio datagram and the client decoded it into
`AudioPCM` — and then never read it. Video's `pts_ns` is used end to end (the
end-to-end meter computes a true glass-to-glass `displayed + clockOffset − pts`
per presented frame), so audio free-ran at whatever depth its jitter ring
happened to reach, video was presented on an independent path, and nothing ever
compared them. The A/V offset was an accident of buffer depths: it moved
whenever the ring ratcheted under underrun pressure, and it got WORSE every time
video got faster, because a quicker decoder lowers the video leg and leaves
audio's exactly where it was.

Video is the master:

  audio_e2e = (now + buffered_ahead + clock_offset) − pts_ns
  av_offset = audio_e2e − video_e2e        (> 0 ⇒ audio behind the picture)

`AvSync` smooths that with an EWMA, ignores what sits inside a deadband no
listener can detect, refuses the implausible outright rather than clamping it (a
wall-clock step must not steer the ring), and proposes a depth. Swift refuses
one thing Rust does not have to: the arithmetic itself. The Rust controller
works in i128, while Swift has no Int128 at this tools version, so the terms are
combined with overflow-REPORTING arithmetic instead of the `&-` the latency
meters use. That is not defensive padding — `ptsNs = 1 << 63` reads as
`Int64.min`, the difference lands on exactly `Int64.min`, and `abs()` of that
has no representable result, so checking the overflow flags AFTER the sanity
limit does not mis-measure the stream, it aborts the process from the audio
drain thread. The guard's short-circuit ordering is what makes the sanity check
safe to run at all.

Continuity outranks sync, always. `AudioRing.setSyncTarget` only ever takes a
REQUEST, clamped between the existing underrun-driven floor and the hard cap. A
link whose jitter genuinely needs more buffer than the picture is away keeps its
buffer and the residual is reported. `nil` is the default and reproduces the
previous behaviour exactly. The clamp raises its ceiling to the floor rather
than using it as-is: a device whose callback quantum alone exceeds the hard cap
makes floor > cap, and a plain `min(max(s, floor), cap)` would then hand back
the CAP — quietly below the continuity floor, inverting the exact ordering this
exists to guarantee, on the awkward hardware it exists to survive. (Rust's
`Ord::clamp` announces that condition by panicking; Swift would just get it
wrong, which is worse.)

The reference is the other half, and without it the loop is inert — which is why
this was split out rather than shipped alongside the Rust side. `LatencyMeter`
now publishes its most recent sample as a LEVEL, so the end-to-end meter the
presenter already writes per presented frame becomes the video figure the audio
plane reads. Both present paths (arrival and deadline) feed it without either
knowing audio exists, and the stage-1 fallback presenter — which stamps no
present at all — offers nothing, so the loop correctly declines to correct. The
level EXPIRES, unlike the Rust atomic: this client has a backgrounded keep-alive
that keeps audio playing and drops video decode entirely, and a reference with
no expiry would go on steering the ring against a figure minutes old and frozen.

And the reason none of this was visible: `bufferedMS`/`targetMS` existed only in
a periodic log line, absent from anything a surface could render. The HUD's
detailed tier now carries `audio buffer N ms · a/v ±N ms` and the 1 Hz stats log
gains the same pair, appended last so existing parsers are unaffected — both
numbers, because a deep ring on a jittery link is correct and only the offset
separates that from audio held late.

`PUNKTFUNK_NO_AV_SYNC=1` disarms the loop without a rebuild, as on the Rust
clients.

Verified: swift build + 225 tests (5 skipped) green. Every new gate was proven
non-vacuous by planting its own defect and confirming the gate caught it — the
continuity invariant, the clamp inversion, the deadband, both refusal paths, the
evidence threshold, the sync-pressure relax, the reference's staleness and its
survival of a drain, and `setSyncTarget` being live at all rather than dead
code, which is how the previous pass in this area shipped a correction that was
structurally unreachable with a green test. Two gates came back VACUOUS on the
first sweep and are the reason their inputs look so specific: the overflow test
was being caught by the sanity limit instead of the overflow guard, and the
refused-reference test was being caught by `latestSample`'s own `> 0` check
rather than by where the publish sits.

enricobuehler 74270109dd ci(android): lint the Android target, which nothing had ever done
`ci.yml` runs `cargo clippy --workspace` on the HOST, where
`clients/android/native` and every `#[cfg(target_os = "android")]` module
elsewhere compile out, and `android.yml` only ever built. So the Android target
was never linted at all — not once. Five lints were sitting in
clients/android/native when this was noticed, in code no gate had ever read.

The gate is a Gradle task rather than a YAML step because cargo-ndk needs a
specific discovery environment (NDK sysroot, SDK cmake 3.22.1 for libopus,
`LIBOPUS_STATIC`, Ninja) and duplicating it into the workflow would let the lint
drift from the build — a lint that ran against a different toolchain is a lint
about a different program. `registerCargoNdkClippy` reuses the build task's
environment verbatim via the extracted `cargoNdkEnvironment`, so local and CI
runs are the same invocation.

It lints BOTH pointer widths, and that is load-bearing rather than thorough:
arm64-v8a is 64-bit and armeabi-v7a is 32-bit, so a cast that is redundant on
one can be required on the other. Linting only the primary ABI would license
"fixes" that break the 32-bit build — the shipping ABI for the many 32-bit
Google TV / Android TV boxes this client targets. x86_64 is skipped: it is
emulator-only and shares its width with arm64, so it costs lint time for no
signal the other two do not already carry.

The five resident lints:

* `audio.rs` / `mic.rs` `type_complexity` — the open-attempt closures now return
  named `OpenedPlayback` / `OpenedCapture` aliases. The two tuples are mirror
  images of each other (playback sends, capture receives), which the aliases now
  say out loud.
* `vsync.rs` ×2 `unnecessary_cast` — **not** taken. `timespec`'s fields are
  32-bit on armv7 and 64-bit on arm64, so the casts are REQUIRED on one shipping
  ABI and redundant on the other; following the suggestion would break the
  32-bit build. `i64::from`/`.into()` do not escape it either, they trade
  `unnecessary_cast` for `useless_conversion` on the 64-bit side. Answered with
  a documented `#[allow]` at the expression instead of in whichever build breaks
  first.
* `pad_audio.rs` `needless_range_loop` — iterator form, preserving the
  `channels < 2` no-op the range had.

Verified: `:kit:cargoNdkClippy` green on both ABIs, host-lane clippy for the
crate still clean, `cargo fmt --all --check` clean. The gate was proven
non-vacuous by planting `1i32 as i32` in an android-only module and confirming
it fails the task, then reverting.

enricobuehler 70e6b80200 fix(client/android): place audio with the picture on Android too
The core, Linux, Windows and host halves of the audio latency overhaul landed
with Android deliberately left inert: `JitterPolicy`'s sync target defaults to
`None`, so this ring kept behaving exactly as it always had. What was missing
was not the loop but its REFERENCE — nothing here published where a frame
actually reached glass, and a controller with no reference is the mechanism you
can prove is present but that cannot act. This wires both halves.

The decode thread now reads the host capture `pts_ns` that every `AudioPacket`
has always carried and that this client, like every other, dropped on the floor.
Against the ring depth (published by the AAudio callback through the shared
`AudioSyncCell`) and the video plane's end-to-end figure it computes

  audio_e2e = (now + buffered_ahead + clock_offset) − pts_ns
  av_offset = audio_e2e − video_e2e        (> 0 ⇒ audio behind the picture)

and asks the ring for a depth that closes it. Only ASKS: `set_sync_target` is
clamped between the underrun-driven adaptive floor and the hard cap, so a link
whose jitter genuinely needs more buffer than the picture is away keeps its
buffer and the residual is reported instead of being taken out of the listener's
stream. Continuity outranks sync, on this ring as on the others.

The reference comes from `DisplayTracker`'s `OnFrameRendered` callback — the one
place in the client that knows a frame truly latched — and it is computed ABOVE
the HUD gate now. A sync loop that only ran while the overlay was up would be
off on exactly the devices that report latency; the stats LOCK stays gated,
which is what that early-return was really protecting. Both decode loops feed
it, so sync works with "Low-latency mode" off as well.

Two deliberate refusals:

* The figure is published RAW. The HUD shaves the OS present floor off its shown
  display/end-to-end numbers — metrics report what Punktfunk controls — but sound
  has to reach the ear when the light reaches the eye, and a floor-shaved
  reference would place audio a whole latch period early on every device.
* Below API 33 there is no render callback, so there is no confirmed present and
  the loop stays inert (target `None` ⇒ today's behaviour exactly). The release
  instant is NOT substituted for it: a release targets a FUTURE vsync and runs a
  whole latch period (8-21 ms measured) ahead of glass, well outside the loop's
  deadband — it would place audio early on every frame while looking like it was
  working.

The plane is also no longer invisible. Ring depth and the smoothed offset ride
the stats array at 33/34 and the Detailed HUD carries `audio buffer N ms · a/v
±N ms`, the same wording the desktop HUD uses — both numbers, because a deep ring
on a jittery link is correct behaviour and only the offset separates that from
audio simply held late. The 1 Hz logcat line gains `av_ms` beside its depth, and
the depth itself now has ONE publisher: the counter copy is gone in favour of the
sync cell both readers already share.

The escape hatch is two levers. `PUNKTFUNK_NO_AV_SYNC=1` keeps the contract the
desktop clients document, but an app launched from the launcher inherits no
environment, so the one a field tester can actually reach is
`adb shell setprop debug.punktfunk.no_av_sync 1` — no rebuild, exactly like
`debug.punktfunk.presenter`. A loop that steers playback has to be bisectable on
the device that reports the regression.

Verified: `cargo ndk -t arm64-v8a check` clean; `cargo clippy -p
punktfunk-client-android --all-targets -- -D warnings` clean on the host lane CI
lints, and the Android target introduces no new findings (5 pre-existing lints in
audio/mic/pad_audio/vsync are unchanged — the android-gated modules are never
linted by the host workspace); `cargo fmt --all --check` clean;
`./gradlew :app:testDebugUnitTest` green. The new HUD test was proven
non-vacuous by planting the defect first — dropping the render call fails its
three positive assertions and leaves the three absence assertions passing, which
is the shape a test that "passes for the wrong reason" would not have.

Reverts half of 1eab4b66 and closes G10's open frame question, both settled by the same
measurement.

1eab4b66 made two corrections to the Apple phone-gyro mirror. The negation was right and
stays: Apple reports the gravity VECTOR, pointing down, while an accelerometer measures
proper acceleration, pointing up at rest, and the wire carries the latter. The frame
change was wrong, and this removes it.

The mistake was a name collision. Two different frames are both called "the controller
frame". GCMotion reports a CONTROLLER in (Right, Forward, Up) — measured on a real
DualSense — which is not the wire's frame, which is why `GamepadCapture.forwardMotion`
converts. The mirror's orientation remap resolves THIS DEVICE into the frame its header
describes, x right, y up, z out of the screen. For the pose that mirror exists to serve —
a phone clipped upright with the screen facing the player — "out of the screen" points at
the player, so that frame is (Right, Up, Backward), which IS the wire's. It was already
correct. Applying the controller path's conversion on top rotated it out of true: a phone
sitting still would have reported gravity as −1 g on the roll axis rather than +1 g up,
i.e. claimed to be lying on its edge.

Reasoning by analogy is what produced it — "the mirror says controller frame, the capture
path says controller frame, so the same fix applies". Both files say it; they mean
different things.

What caught it was measuring the Android twin, which does the same thing straight through.
On glass: a DualSense on Bluetooth to a phone, streaming to a Linux host, reads +1 g on the
up axis end to end. Had the Apple mirror needed a conversion, the Android one would have
needed the same one and would have been visibly wrong. It is not.

The same run settles G10's frame, which shipped straight-through and explicitly unverified
because nobody had put a Bluetooth pad in front of the platform sensor framework. Now
somebody has. `PadSensors`' own first-sample log read `accel 0, 10000, 0` — exactly 1 g on
slot 1 — and at the far end hid-playstation published gravity as +0.991 g on ABS_Y, with
every rotation driving its correctly-named axis and the signs agreeing with gravity's
independent witness on 95 of 100 rotating samples. Android hands a controller's sensors
over in the pad's own frame, as documented. No remap, and the comment now says measured
instead of assumed.

Worth recording why the earlier suspicion was wrong, since it is the same trap in the other
direction: Android's DEVICE sensor frame really does put +z out of the screen, so a flat
phone puts gravity on z — but a CONTROLLER's sensors are reported in the controller's
frame, not the phone's. One platform, two conventions, chosen by what the sensor is
attached to.

Gate: Apple macOS `swift build` + full suite (215 tests, 5 skipped, 0 failures) and the
iOS-triple typecheck, which is what actually compiles `DeviceGyro.swift`; Android
`:kit:compileDebugKotlin`, `:kit:testDebugUnitTest`, `:app:compileDebugKotlin`. Green.

Still owed: `DeviceGyroRemap`'s four orientation matrices remain derived — this run used a
controller's own sensors, not the mirror, so it says nothing about them. They need a
gyro-less pad on wire index 0 and a phone turned through all four orientations.

Follow-up to the G10 merge. The new sensor path was written against main, which does not
carry this branch's G8 work, so it forwarded motion unconditionally — the one thing G8
exists to stop.

`deviceMotion` checked `forwarding` and nothing else. A Bluetooth DualSense in a session
that resolved to an X-Box backend would stream ~200 Hz of samples the host parses and
discards, for the whole session, exactly as the USB capture path did before G8. Not a
regression against shipped behaviour — the path is new — but it would have shipped the
defect back into a client that had just been taught not to have it.

`Slot` now carries `motionReaches`, asked once at open off the kind that pad DECLARED, in
the same shape `ExternalPad` already used. Per pad, not per session: under Automatic the
handshake carries the active pad's kind, so a couch with an X-Box pad on slot 0 and a
DualSense on slot 1 must not have slot 1's working gyro suppressed by slot 0's answer.

The notice moved to where the truth is known. `openSlot` knows only what kind a pad
declared, not whether it physically has a gyro — that is discovered later, when
`PadSensors` finds a gyroscope and calls `setDeviceHasSensorMotion`. Raising it there is
the only placement that both tells a player whose gyro is being dropped and stays silent
for the pads that never had one.

Also unified the last duplicate scale in the module. G10 hoisted the wire units into
`Gamepad` and pointed `DeviceGyro` at them, but `DsDevice` kept its own `20L` / `10000L`
— and `Gamepad`'s new comment claims every sender goes through one place, which was not
yet true. Two copies of a unit constant in one module is precisely the defect this program
opened with (a DualShock 4 blob 40× hot because a second copy had drifted), so the claim
and the code now agree. `val` rather than `const val` only because widening to Long is not
a constant expression; Long is deliberate, since the calibration arithmetic overflows an
Int before it divides.

Proven non-vacuous rather than assumed: changing `Gamepad.MOTION_GYRO_LSB_PER_DEG_S` from
20 to 16 now fails four named cases across three classes —
`DsDeviceTest.calibrationRescalesRawCountsOntoTheWireUnits`,
`.theHostsOwnBlobIsAPassthrough`, `.parseStateAppliesTheCalibration` and
`DeviceGyroTest.wireUnitConstants`. Before this change `DsDevice` would not have noticed.

The gate itself has no test, for the reason the surrounding code already documents:
`GamepadRouter` needs Android plus a live JNI handle, there is no Robolectric in this
module, and a mock would test the mock. It is argued at the call sites instead.

Gate: `:kit:compileDebugKotlin`, `:kit:testDebugUnitTest`, `:app:compileDebugKotlin`,
`:app:testDebugUnitTest` — kit 75 / app 67, 0 failures, counts read out of the JUnit XML.
The merge reconciles: 62 on this branch, plus 6 from main's DeviceGyroTest, plus G10's 7.

enricobuehler 8f1081719f feat(client/android): a Bluetooth controller's gyro stops going nowhere
Android had two motion sources and both of them are USB claims. DsCapture
takes a Sony pad's HID interface away from the kernel; Sc2Capture does the
same for a Steam Controller 2. Everything else — a DualSense, a DualShock 4,
a Switch Pro, an 8BitDo, paired over Bluetooth — arrives as an ordinary
InputDevice. Its buttons worked, its sticks worked, and its gyro was dead,
silently, with no log line and nothing in the UI to suggest the pad had a
sensor at all. That is not one controller, it is the whole class of
controllers people actually pair to a phone.

The platform has had the answer since Android 12: InputDevice.getSensorManager
hands back a SensorManager scoped to that one controller, carrying its
TYPE_GYROSCOPE and TYPE_ACCELEROMETER. PadSensors registers a listener per
forwarded pad that has a gyroscope and sends the samples on that pad's wire
index. Below API 31 it registers nothing and the pads behave exactly as they
did.

It is built on DeviceGyro's shape, because the phone mirror had already paid
for these lessons. One dedicated HandlerThread, never the main one. Batching
off (maxReportLatencyUs = 0) — batching would trade away precisely the latency
gyro aim exists to avoid. 200 Hz requested, which is also the ceiling the
framework grants an app without HIGH_SAMPLING_RATE_SENSORS, so asking for more
would only be capped. And a feed that lets go of a pad still alive parks its
rotation at zero first: the host holds motion as state and re-emits it in every
virtual-pad report, so an angular velocity left behind is a pad that rotates
forever.

Two writers on one pad's motion is the failure this program has spent the day
unpicking, so the coordination is explicit in three places. A USB capture wins:
DsCapture.startUsb already calls releaseDevice at claim time, that closes the
slot, and the close now also takes the sensor listeners off — the claim makes
the InputDevice vanish anyway, but going through the explicit teardown is what
makes the ordering deterministic instead of a race against the platform's own
removal callback. The phone-gyro mirror stands down: registering flips a bit
the router reports through padHasOwnMotion, which DeviceGyro re-reads on every
sample and answers with its own zero park. And a pad with an accelerometer but
no gyroscope is deliberately NOT taken — it could only send gravity while
pinning rotation at zero, on a pad the mirror is otherwise entitled to speak
for, which is the same fight in a quieter costume.

The wire units are measured fact (punktfunk_core::input::gamepad: 20 LSB/deg·s,
10000 LSB/g), and they now live in exactly one place on this client:
Gamepad.motionGyroWire / motionAccelWire, which DeviceGyro was hand-inlining a
second copy of. The gyro program's first finding was a client sending 40x hot
because a second copy of a number had drifted, and the merge that followed
found a sender nobody remembered to correct. One function, both callers.

THE AXIS FRAME ON THIS PATH IS NOT VERIFIED, and the mapping is deliberately
straight through rather than guessed at. What is known: the wire is a unit
passthrough into a virtual DualSense report, and that report's frame was
measured over raw HID on 2026-08-07 as (Right, Up, Backward-toward-the-player)
carrying (pitch, yaw, roll), right-handed — which is why the USB path forwards
the pad's own order un-remapped and is correct to. Android documents its sensor
frame for a handheld device as +x right, +y up, +z out of the face, the same
frame once "the face" is read as the one the player looks at. So straight
through is what the documentation implies. What nobody has done is put a
Bluetooth DualSense in front of the platform sensor framework and compare —
those numbers come through a HID driver and InputFlinger's sensor mapper,
either of which could permute or negate without saying so. A plausible-looking
wrong remap is exactly the bug this program keeps finding, so the code says
unverified and names the measurement that settles it, and each feed logs its
first converted sample so the cheapest half of that measurement — which slot
gravity lands on with the pad flat and still — costs a logcat line.

PadSensorsTest pins the scale, the clamp, the rounding and the straight-through
order, mutation-checked four ways: 20 to 16 fails gyroScaleFromRadiansPerSecond
and straightThroughFrame, reversing the axis order fails straightThroughFrame,
truncating instead of rounding fails roundsToNearestNotTowardZero, and negating
the accel fails restingPadIsTheHostNeutral. Its frame expectations are written
to change together with any remap that lands, not to be edited around one.
GamepadRouter needs Android and a live JNI handle and there is no Robolectric
here, so its half is argued in comments beside the code, as DsCapture's claim
ordering already is.

Gates: kit 65 tests (58 before, plus 7), app 67 unchanged, 0 failures, read out
of the JUnit XML rather than off a green build.

enricobuehler 979ed8f426 docs(clients/pads): say that an X-Box virtual pad has nowhere to put motion
G17's motion half. The docs described what the CLIENT sends and stopped there, which
made a promise the host does not always keep.

The support matrix said a desktop client forwards motion from any pad SDL exposes a gyro
on "and the host injects it into the matching virtual pad". The first clause is true; the
second is only true when the virtual pad has a motion plane. The X-Box 360 and One
backends do not — no gyro in their HID contract — so the host parses every sample and
discards it. That is where *Automatic* lands anything it does not recognise as Sony or
Valve, an 8BitDo with a perfectly good gyro included, and where a Switch Pro lands on a
Windows host with no `hid-nintendo` backend to fold it into.

A reader following the old text would conclude their gyro was broken. The failure has no
other symptom: motion just does nothing.

So both pages now say what to do about it — pick a DualSense-class type — and the
client-settings page says it where the choice is actually made, next to the degrade
paragraph that explains why a session ends up on an X-Box pad in the first place.

The Deck's Steam-Input requirement moves out of Decky's settings blurb, which is the one
place a Deck user streaming FROM the Deck would never look. With Steam Input on, Steam
hands the app its own virtual X-Box pad, so no controller-type choice can help: there is
no gyro on the pad the client can see.

The picker help text now mentions motion on GTK and Android, which is where it was
missing — Windows already said it and Apple says it in its own words. One sentence, the
same sentence, so the four clients answer the question the same way.

This is the doc side of the on-screen notice that shipped earlier in this branch. The two
exist for the same reason and now agree: the client says it when it detects the case, the
docs say it when someone goes looking.

Not covered: the preset COUNTS in note 1 ("Android and the console home offer six …
Windows and Apple offer five") are still unverified against the four pickers, and the
Apple picker's missing Steam Deck entry is a code gap rather than a doc one. Both are
noted in the plan and left for their own change rather than guessed at here.

Gate: Linux CI image fmt + `clippy --locked --all-targets -D warnings` on
punktfunk-client-linux (the GTK string is compiled) plus the core crates and their tests;
Android `:app:compileDebugKotlin` + `:app:testDebugUnitTest`. Green.

Surfaced by the merge. `DeviceGyro`'s header states the contract plainly — "units and
axis semantics match `GamepadCapture.forwardMotion` exactly … the same convention, so a
future sign/scale correction lands in one place for both sources" — and this branch made
two such corrections in only one of the two places. That is a promise the code stopped
keeping the moment the controller path was fixed.

Both were true parity when #88 was written; both broke here.

**The negation.** `GamepadCapture` sends `-(gravity + userAcceleration)` because Apple
reports the gravity VECTOR, pointing down, while an accelerometer measures proper
acceleration, pointing up at rest — and the wire carries the latter. The mirror sent it
un-negated, so a phone lying still told the host it was accelerating downward at 1 g.
The comment above that line even claimed the convention matched.

**The frame.** The mirror's remap targets the controller frame its own header describes —
x right, y up, z out of the screen — which is exactly GameController's frame, and that is
not the DualSense report frame the wire is defined in. So the same change of basis the
controller path now takes applies here, after the orientation remap rather than instead
of it: the remap resolves which way the phone is being held, and the basis change
translates the result into the pad's language. Two different jobs that happen to compose.

Order matters for the closing sample too. `stop` replays `lastAccel` beside a zero gyro
so "rotation stopped" does not also read as free fall; `lastAccel` is recorded after both
conversions, so what gets parked is what was actually sent.

Left alone deliberately: `DeviceGyroRemap` itself and `DeviceGyroRemapTests`. The
orientation matrices answer a different question — which way is the phone being held —
and nothing measured this evening bears on them. They remain derived-not-verified, as
their own doc says, and the on-glass pass that owes the controller path a check owes them
one too, in all four orientations.

Gate: macOS `swift build` + full suite (215 tests, 5 skipped, 0 failures) and the
iOS-triple typecheck green — the latter is what actually compiles this file, since the
whole thing is `#if os(iOS)`.
2026-08-07 19:34:51 +02:00
enricobuehler 5a4305c072 merge: bring current main into the gyro correctness branch
main moved ~60 commits while this branch was in progress, and one of them matters
here: PR #88 (the phone-gyro mirror) landed, touching the same motion path.

One conflicted file, `GamepadCapture.swift`, in three places — all of them the two
changes meeting rather than disagreeing:

- **Slot fields.** #88 added `motionSent` + `lastAccel` for its flush-parks-motion fix;
  this branch removed `lastMotionNs` with the 4 ms drop-throttle. Kept both decisions:
  the parking state stays, the throttle field goes.
- **forwardMotion's head.** #88 added the mirror stand-down (`pad 0` yields while the
  phone speaks for it); this branch deleted the throttle guard. Kept the stand-down,
  dropped the guard.
- **The send.** This branch converts into the DualSense report frame; #88 records what
  went out so `flush` can replay it beside a zero gyro. Both, with the recording placed
  AFTER the conversion — `flush` replays `lastAccel`, so it has to be the vector that
  actually went on the wire, or a still pad's gravity gets parked in the wrong axis.

The two features compose exactly, which is worth stating because it is not luck: this
branch gates motion capture on `hasRotationRate`, and #88 engages the phone mirror when
`hasRotationRate != true`. They are complements — a pad either drives its own gyro or the
phone mirrors for it, never both and never neither.

Everything else auto-merged. Note `DeviceGyroRemapTests` is `#if os(iOS)`, so the macOS
suite reports the same 215 as before the merge rather than gaining #88's six — checked,
not assumed.

Gates re-run against the merged tree rather than trusting either side's: Linux fmt +
build + `clippy --locked --all-targets -D warnings` + punktfunk-core and pf-inject
suites; Apple 215 tests and the iOS-triple typecheck; Android kit + app compile and
tests. All green.

G13 — the three capture-fidelity findings from the gyro sweep, two fixed and one
argued.

**The 4 ms floor was a DROP, and it was shedding real rotation.** A sample arriving
3.9 ms after the last one was discarded outright. That is the wrong shape for this
signal: buttons and sticks are absolute state, so a dropped frame costs nothing — the
next one says everything it would have. Angular velocity is a RATE, and a consumer
integrates it into an angle, so a dropped sample is rotation that happened and can never
be recovered. GameController's delivery jitters around the pad's own ~250 Hz, so a floor
set AT that rate does not shed a rare extra sample; it sheds a steady fraction of every
turn. And the error is one-signed, so it accumulates — aim drifting short, which reads
as bad sensitivity rather than as a bug.

Nothing needed the ceiling. GC delivers at the sensor's rate rather than faster, the SDL
client has always forwarded every sample, and the host's idle watchdog is a 100 ms
timeout this cannot outpace. The throttle's two fields went with it: `lastMotionNs` was
left set-but-never-read once the guard was gone, and `motionIntervalNs` had no other
consumer. (Notes elsewhere say `flush` parks motion and reads it — that is PR #88's
branch, not this one. Checked rather than assumed.)

**An X-Box pad was streaming gyro it does not have.** Capture attached to any `GCMotion`,
and an X-Box controller exposes one that reports gravity and NOTHING else. So the client
sent a permanently-zero `rotationRate` to the host as authoritative gyro, under a
declaration saying this pad has one. That is worse than having no motion plane at all: a
game sees a controller being held perfectly still forever, and there is nothing to fall
back to and nothing to notice. Now gated on `hasRotationRate`, which is GameController's
own answer to the question we actually mean.

The settings badge had the same bug from the same cause — `hasMotion` was
`motion != nil`, so an X-Box pad got a gyroscope icon. It now reads `hasRotationRate`
too. One wrong predicate was driving both the UI promise and the wire behaviour, which is
why they were wrong together.

That also simplifies G8's "your gyro can't reach this session" notice, which had to test
`hasRotationRate` itself to avoid nagging about a gyro the pad never had. With the attach
gated on it, the notice is just the else-branch.

**Motion stays on the main queue, and this is the argument for why.** GameController's
`handlerQueue` is a property of the CONTROLLER, not of an element, so moving motion off
main moves buttons, sticks, the touchpad and the escape chord with it. This class is
`@MainActor` throughout — eight `assumeIsolated` sites, the slot table, the gesture
timers — so that is a rewrite of the isolation model rather than a queue assignment, and
it would put the tvOS escape chord (the only controller way out of a stream there) on a
background queue. That is a real risk for a speculative gain. The comment says so at the
call site, and names the measurement to make first if it ever does bite: the host's
per-pad motion inter-arrival histogram already reports exactly this and would say whether
the delay is client-side or on the wire.

Gate: macOS `swift build` + the full suite (215 tests, 5 skipped, 0 failures) and the
iOS-triple typecheck green. No test pins the throttle removal or the capability gate:
both are properties of live `GCMotion` delivery, which this module cannot fake — there is
no injectable seam, and inventing one to assert "we called sendMotion twice" would test
the mock. They are argued at the call sites instead, in the same spirit as the parts of
`DsCapture` that are not unit-testable in their module either. On-glass verification is
owed with the two already outstanding on that rig.
2026-08-07 19:12:02 +02:00
enricobuehler efb7f99129 fix(client/apple): motion arrived in the wrong frame — measured against a real pad
G16 step 1, and the second half of what 9e9bb9f4 started. That commit fixed the SIGN
of acceleration (Apple reports the gravity vector, pointing down; a pad reports proper
acceleration, pointing up). This fixes the FRAME, which is a separate defect and was
never going to show up as an inverted axis — it shows up as roll where the game reads
yaw.

The wire is a unit passthrough. `dualsense_proto::write_report` puts gyro[0..3] and
accel[0..3] straight into the virtual pad's report bytes 16.. and 22.., in order, with
no permutation — the same slots a real DualSense fills. So the frame the wire is
DEFINED in is the pad's own report frame, and forwarding GameController's x/y/z
unconverted was speaking a different language with the same vocabulary.

Both frames measured 2026-08-07 from ONE physical DualSense on one desk, read twice —
over raw HID and through GameController — so this is two readings of the same
controller in the same orientations rather than two documents:

  DualSense report frame: (Right, Up, Backward)   axis 0 pitch, 1 yaw, 2 roll
  GameController frame:   (Right, Forward, Up)

Right is already slot 0; Up is GC's z and moves to slot 1; slot 2 wants Backward, which
is GC's y negated. Hence (x, z, -y), applied to gyro AND acceleration because it is a
change of basis and both live in that basis.

Notable: the wire's documented naming was right all along — gyro[0]=pitch, [1]=yaw,
[2]=roll is exactly what the hardware does. And Android needs no remap at all: it
forwards the pad's own axis order un-remapped, which is correct. Its old reading was
purely the scale bug f6de620f fixed. Only Apple was converting nothing.

How the hardware frame was established, since a wrong frame here is invisible. Gravity
at rest put +0.997 g on axis 1. Yaw clockwise-from-above drove axis 1 negative (98% of
the rotation), pitch nose-down drove axis 0 negative (100%), roll right-side-down drove
axis 2 negative (95%) — plain right-hand rule, and (a0 x a1 = a2) confirms the triad is
right-handed. The accelerometer then corroborated the gyro's assignment independently:
under pitch-down axis 2 rose 0.160 -> +0.339 (nose down raises the back, so world-up
gains a Backward component) and under roll-right-down axis 0 went +0.021 -> -0.197,
while yaw left acceleration untouched. Two different physical quantities agreeing on
one triad.

Apple's frame took four attempts, and the failures are worth recording because each was
a different way to be confidently wrong:
  - peak |w| over a window containing BOTH the tip-down and the return stroke can record
    the return, with the opposite sign. Yaw (a continuous one-way spin) was unaffected;
    pitch and roll were exactly the two that disagreed with everything else.
  - reading `gravity + userAcceleration` when `hasGravityAndUserAcceleration` is FALSE
    yields a constant (0,0,1) in every orientation. It looks like data. The tell is that
    it never moves. The client's own else-branch on `m.acceleration` is the correct read
    and is what the instrument now mirrors.
  - `da/dt = -w x a` holds only for gravity, so testing it during vigorous waving — when
    `m.acceleration` carries inseparable linear acceleration — fits nothing.
The frame that survived all of that: static poses, three of them, three repetitions
each. Nose-down moved axis 1 by -0.635 (so axis 1 is Forward), right-side-down moved
axis 0 by -0.686 (so axis 0 is Right), flat put +0.99 on axis 2 (Up). That conclusion
holds whether or not the acceleration negation is right, because negating flips the
measured vector and the physical direction it represents together.

Confidence, stated honestly. The accelerometer half is solid: nine pose measurements,
and mapping the flat pose through gives (+0.005, +0.992, +0.192) against the hardware's
own (+0.021, +0.997, +0.160) — all three components, including the small tilt term that
is what distinguishes this mapping from the five other permutations that also put
gravity on slot 1. That the gyro shares the frame unmodified rests on a weaker
measurement: a gravity-dominated consistency test that preferred (+x,+y,+z) by 1.22x,
which is a margin, not a landslide. It is corroborated by the yaw reading (the one
rotation measured without the return-stroke ambiguity) agreeing with right-hand rule in
that frame, and by the peak-vs-return mechanism explaining the two that did not. A
device-side confirmation is still owed and is listed below.

The tests carry the measurements, not just the conclusion. Resting gravity is asserted
against BOTH readings of that pose; each rotation is asserted to reach the slot the wire
reads it from; and two properties guard the shape rather than the numbers — that the
conversion is an isometry (a basis change may not stretch anything) and that it
preserves handedness. That last one matters most: a permutation with the wrong number of
sign flips is a REFLECTION, which looks plausible axis by axis and inverts every
rotation. Mutation-checked: dropping only the negation fails 6 assertions across 4 of
the 5 cases, the handedness test among them.

Owed, and not claimed done: on-glass re-verification through a real iOS device, together
with the two already owed on that rig (the 9e9bb9f4 sign fix and the Android
calibration read) — one pass covers all three. G14's DualSense neutral acceleration is
now unblocked by this measurement (1 g on slot 1, not the z-up the notes assumed) but is
deliberately left to its own change; and that constant must NOT be propagated to
switch_proto, which is a different device whose frame nobody has measured.

Gate: macOS `swift build` + the full suite (215 tests, 5 skipped, 0 failures) with the
five new cases observed in the run's own output, and the iOS-triple typecheck green.

enricobuehler 7cab7ae6bc feat(client/android): say when a captured pad's gyro can't reach the session
G8's Android half, and the last of the three clients. Same failure as the other
two: a controller with a gyro, in a session whose virtual pad has no motion
plane, does nothing when tilted — silently, with no way from the couch to tell
that apart from a broken sensor. The fix is the Controller type setting, so the
notice names it.

Android read neither the requested nor the resolved backend, so this needed a
plumb. What it did NOT need was a third copy of the rule. `nativePadMotionReaches`
takes the kind a pad declared and answers off `pad_motion_reaches` in
punktfunk-core, where the argument and the tests already live. The rule is
subtler than it looks — the host builds each pad from its OWN declaration and
folds what it cannot build, so neither the declaration nor the session echo
answers it alone — and every way of getting it wrong is silent. A Kotlin
transcription would have been a third thing to keep in step with the host, which
is exactly how the SDL half got it wrong the first time.

Asked once per pad, at claim, in `openExternal` — where the pad's kind is already
being declared to the host — and the answer held for the pad's lifetime on the
`ExternalPad`. Not per sample: this runs at a DualSense's full report rate.

`hasGyro` gates only the NOTICE, and defaults to false. `DsCapture` passes true —
every pad it captures is a Sony one whose IMU is a headline feature, forwarded on
the rich plane. `Sc2Capture` keeps the default, because the Steam Controller 2's
motion rides inside the opaque passthrough report that `hidReport` carries, which
nothing here may second-guess: warning about motion for a pad that never calls
`motion()` would be a notice about a feature the player never lost. The
suppression itself is on `motion()` regardless, where it costs a dead pad nothing
and stops a live one paying to send samples the host will decode and discard.

The notice sits at the BOTTOM of the stream overlay, unlike the mic-chord
confirmation at the top. The two can coincide — a pad is claimed at roughly the
moment someone might be muting — and one landing on the other would cost the user
both. It holds 6 s rather than the mic chord's 1.6: that one confirms something
the user just did, this one explains something they did not, in a sentence they
have to read. Nulled at teardown beside `onExitArmed`/`onMicChord`, for the same
reason those are — a slot closing during release must not poke Compose state on
the way out.

Not covered by tests, and this is a limit of the module rather than a choice:
`GamepadRouter` needs Android plus a live JNI handle, there is no Robolectric
here, and the predicate it defers to is pure Rust that already has its table. So
the parts that carry the reasoning are argued in comments, as `DsCapture`'s
claim/teardown ordering already is. What IS mechanically verified is the piece
that a compiler cannot catch and a device would fail on: the JNI symbol
`Java_io_unom_punktfunk_kit_NativeBridge_nativePadMotionReaches` is present and
global in the built arm64-v8a `.so`, so the `external fun` resolves rather than
throwing `UnsatisfiedLinkError` at the first pad.

Gate: `:kit:compileDebugKotlin`, `:kit:testDebugUnitTest` (62 cases, 0 failed,
read out of the JUnit XML rather than inferred from a green build — unchanged
from this branch's previous count), `:app:compileDebugKotlin` and
`:app:testDebugUnitTest` (67 cases, 0 failed), with `:kit:cargoNdkRelease`
rebuilding the JNI crate clean across all three ABIs, plus `cargo fmt --check` on
it. On-glass verification is owed on the rig the earlier legs used, and is worth
doing as one pass with the two already owed there.

enricobuehler aaa58ad817 feat(client/apple): say when a pad's gyro can't reach the session, and stop powering it
G8's Apple half — the UI hint 77797a9e left owed, plus the suppression, which on
this client is worth more than it was on the SDL one.

The failure being fixed is entirely silent. A controller with a gyro, in a session
whose virtual pad has no motion plane, simply does nothing when tilted: nothing
in the app says so, and from the couch a session that resolved an X-Box backend
is indistinguishable from a broken sensor. The fix is the Controller type setting,
so the hint has to name it — a badge that only said "motion unavailable" would
leave the player exactly as stuck.

Asked per pad, off what the slot declared, via the predicate punktfunk-core now
carries. `GamepadCapture` is the one client where this is naturally per pad
already: `openSlot` computes `manager.declaredKind(for:)` and puts it in
`slot.pref`, so the question is answered where the pad is opened rather than on
every sample. `GamepadType.motionReaches(declared:asked:resolved:)` is static and
pure so it can be tested without a live session; the connection's instance method
fills in the two halves it owns, and `requestedGamepad` is stored beside
`resolvedGamepad` for the same reason it exists in the Rust client — the echo is
only this pad's answer when the pad declared what we asked for.

Where Apple differs from the SDL client, and better: it never powers the IMU. The
existing code already declined to activate sensors when forwarding was off,
reasoning that with nothing to forward there is no reason to make the pad stream
gyro over Bluetooth and burn its battery — `closeSlot` is careful to power them
back down for exactly that reason. A host that built this pad a backend without a
motion plane is the same situation, so it takes the same branch. No per-sample
check, no handler attached, and a DualSense in an X-Box-class session stops paying
for a sensor nobody reads.

The hint fires only for a pad that really has a gyro (`motion.hasRotationRate`).
A gravity-only GCMotion — what an X-Box controller exposes — would otherwise
produce a notice about a feature the player never had. That is a narrower
condition than the capture path itself uses, deliberately: making the capture
gate agree is G13's job and its own change.

The badge sits in the bottom-centre stack with the muted-mic badge and the
start-of-stream banner, at every stats tier and with the overlay off, because
this is not a statistic. Unlike the mic badge it is not a control: the setting is
not reachable mid-stream on every platform and applies from the next session
anyway. So it states the fact, names the setting, and leaves after the banner's
same 6 s. Every platform including tvOS — a DualSense on an Apple TV is an
ordinary way to play, and is exactly the pad this happens to. The model owns the
expiry rather than the view, so a second pad's hint replaces the first cleanly
instead of stacking, and ending the session cancels a pending clear rather than
carrying a stale hint into the next stream.

Non-vacuity proven by mutation, not assumed: collapsing the predicate to
`resolved.hasMotion` fails 4 assertions, including the mixed-pad row that is the
whole reason it is not a session-level check. The table mirrors the Rust one row
for row — a client that disagrees with the host here either kills a working gyro
or streams ~250 Hz into a void, and both are silent.

Gate: macOS `swift build` + the FULL suite (210 tests, 5 skipped, 0 failures) with
the two new cases observed in the run's own output, and the iOS-triple typecheck
green (`arm64-apple-ios17.0`, iOS slices + hand-assembled xcframework per the
memory recipe) — the badge and the overlay it joins are on every platform, so the
macOS build alone would not have covered them. tvOS remains unverifiable from
this Mac; the badge deliberately reuses the neighbouring banner's shape rather
than introducing anything tvOS-specific.

  16:25:49.093  mic capture: 48000 Hz, 1 ch          <- tap installed, format fine
  16:25:49.235  audio engines joined - voice processing active
  ... 13 s of session, no errors, and the 10 s silence verdict NEVER fires

The engine started clean and the tap was installed against a valid
format - so neither the format timing nor the encoder was the fault. The
tripwire fires after ten seconds of CAPTURED frames and never fired
across a 13-second session: the tap received nothing at all.

Because the capture side must be pulled, and only the render graph pulls
anything. On the combined engine the input node carried a tap and no
connection, so it was not in the graph and nobody drove it: the IO unit
came up (the recording indicator lit for a beat, then went out as the
input went idle) and not one buffer ever reached the tap. No error, no
failed start - a session that quietly sent no microphone.

The input now runs through a silent sink into the main mixer, which is
what Apple's own voice-processing sample does. outputVolume = 0 because
the mic must reach the graph and never the speaker. The split path never
needed this - a capture-only engine has the input node AS its graph - so
this broke exactly when the combined topology became the default.

Verified: swift build (macOS), swift build --triple arm64-apple-ios17.0,
swift test 208 passed. Awaiting the reporter's on-device confirmation.

enricobuehler 8e8d30202c fix(client/android): a Sony pad's buttons no longer wait on its calibration
Supersedes the parse gate in 26b0819f. The off-thread read, the claim token, the
teardown ordering and its bounded wait all stand — only what happens in the gap
changes.

26b0819f held every report back until the calibration read came home, so a pad
that stalled on EP0 could feel dead for up to the link's 250 ms timeout: no
buttons, no sticks, nothing. Reports are now forwarded immediately and their
motion scaled by the nominal calibration until the real one lands.

That gap is exactly the behaviour that shipped before f6de620f — acceleration
~18% short, gyro unscaled — for about a millisecond. Nobody can feel that. A
controller that ignores a button press for a quarter of a second is not in the
same category, and it is the only one of the two a user would ever report.

It is also the safer of the two conservatisms available here. The rejected third
option, forwarding motion as zeroes until the real numbers arrive, would have the
host read a still pad as being in free fall — a lie about the physical world
rather than an imprecision about it. The nominal constants are merely a slightly
wrong scale.

The token is more load-bearing under this, not less. With a gate, an unpublished
calibration meant "parse nothing"; now it means "scale nominally", so begin()
clearing the previous pad's value is the whole reason a re-claim falls back to
the nominal constants instead of silently inheriting factory numbers belonging to
a different unit — which are, in general, further off than nominal. The fallback
therefore lives in the hand-off itself (MotionCalHandoff.effective) rather than
as an elvis at the call site: restoring the gate now means changing the type's
API, not deleting three characters in onReport.

The tests moved with the contract. They assert the nominal calibration is what is
in effect during the gap, rather than merely that the slot is empty — an empty
slot is now compatible with either behaviour, so asserting on it would have let
a regression pass. Added the case the change exists for: the same raw report,
parsed either side of publication, forwards identical buttons and sticks while
its gyro and acceleration convert differently. Mutation-checked three ways —
dropping the nominal fallback fails all five cases, dropping begin's clear fails
the inheritance case, dropping the token check fails three.

Gate: `:kit:compileDebugKotlin`, `:kit:testDebugUnitTest` and
`:app:compileDebugKotlin` green on a forced clean rerun, 62 cases across the
module, 0 failed, with the five hand-off cases read back out of the JUnit XML.
The on-glass re-verification f6de620f owes is still owed and unchanged.

enricobuehler 26b0819f5c fix(client/android): plugging in a Sony pad could hitch the interface
Supersedes the synchronous calibration read f6de620f shipped an hour ago. The
ordering it protected is kept; the blocking it cost is not.

f6de620f read the pad's calibration inline in DsCapture.startUsb, which runs on
the main thread — the stream's setup path, and the USB-permission broadcast. The
read is a blocking EP0 control transfer: a pad that is there answers in about a
millisecond, but a pad that is stalling takes the link's whole 250 ms write
timeout, and either way the interface was waiting on a controller. That is the
wrong thread for it.

It now runs on its own daemon thread, one per claim, named pf-ds-cal — the same
shape HidUsbLink already uses for its reader rather than a second style. A
pathological stall now delays the pad's motion by a moment instead of freezing
the UI.

What kept the ordering honest before was "assign the calibration before `model`",
since `model` is what lets the link thread into the parse. That reasoning stands,
so the gate simply moved: MotionCalHandoff holds the claim's calibration, starts
null, and onReport parses nothing until it lands. No report is ever scaled by the
last pad's numbers — those are per unit — nor by the nominal fallback the real
read is about to replace. Dropping the first millisecond of a capture costs
nothing: the reports carry absolute state, so the next one says everything the
dropped one would have.

The calibration is what got deferred, not `model`, and that is deliberate.
Keeping `model` synchronous keeps isActive, the teardown writes, the feedback
sinks and the active-changed true/false pairing meaning exactly what they meant
yesterday — and, more to the point, it makes a late completion structurally
unable to resurrect a dead capture. A straggler can only ever publish a
calibration, and nothing is parsed while `model` is null.

Teardown, which is where this sort of change actually bites. Both stop() and the
unplug path end the claim before they close anything: ending burns the token, so
a read that lands afterwards publishes nothing and says so in the log. They then
wait, bounded at 500 ms and normally already over, for the read to let go of the
connection they are about to close — closing a descriptor with a transfer in
flight pulls it out from under the kernel, the same rule the pad-audio borrow
follows. It cannot deadlock: the reading thread blocks on the EP0 transfer and on
the hand-off's own monitor, never on anything a teardown holds. If a pad has
stopped answering entirely the wait elapses and teardown proceeds regardless,
which is the same exposure the feedback writes already carry and better than an
interface that never comes back.

Tested where it is testable. MotionCalHandoff is the piece that carries the
hazard and it is pure, so it has its own test: nothing is visible until the read
lands, a read that outlived its claim publishes nothing, a re-claim never
inherits the previous pad's calibration, and a doubled end still refuses every
outstanding token. Mutation-checked both ways — deleting the token check fails 3
of them, deleting begin's clear fails the fourth.

Not covered: DsCapture's own claim/teardown ordering is not unit-testable in this
module — there is no Robolectric, and the class builds a main-Looper Handler and
needs a UsbManager — so it is argued in comments rather than pinned. The on-glass
re-verification f6de620f owes is unchanged and still owed.

Gate: `:kit:compileDebugKotlin`, `:kit:testDebugUnitTest` (61 cases across the
module, 0 failed) and `:app:compileDebugKotlin` green, with the four new cases
confirmed present in the JUnit XML rather than assumed from a green build.

Field report: mic uplink dead on iOS, iPadOS and macOS alike, while
Android on the same host works - so the host and the wire are fine.

Two defects in the combined (voice-processing) engine, which became the
default on all three Apple platforms a week ago and has never run on a
device - CI only runs swift test on macOS, and the loopback test counts
datagrams without decoding them.

- The tap read the input format before the engine was prepared. Enabling
  voice processing swaps the engine's IO unit for the VPIO one and
  renegotiates its formats; until prepare() the input node can still
  report the pre-swap state, 0 Hz / 0 channels included, which
  installMicTap correctly refuses as 'no usable input device'. Both
  topologies now prepare first, so the chain is built against what the
  voice processor actually emits.

- A mic chain that failed on the voice-processed engine took the whole
  uplink down for the session: that arm fell back to playback ONLY. The
  sibling failure a few lines above - the voice processor refusing to
  engage at all - already falls back to the split path, which is a
  working mic without echo cancellation. Both arms do that now. The mic
  outranks the AEC.

Not reproduced locally (no Punktfunk entries in this Mac's log store,
and collecting the device's log needs root), so this is a strong
inference plus one proven logic defect rather than a confirmed fix. If
it persists, Console filtered to subsystem io.unom.punktfunk / category
audio names the stage: 'mic capture: N Hz' then 'audio engines joined'
then, 10 s in, either 'mic uplink OK - peak ...' or the SILENCE warning.

Follow-up worth doing separately: nothing reports whether the uplink
actually opened, so the HUD offers a Mute Microphone button over a
session sending nothing. Android gates that on a real micRunning signal.

Making the HUD concentric with the physical display corner had no upper
bound, so a modern phone (~62 pt of display radius) asked for a 48 pt
corner on a card whose lines sit 10 pt from the edge. A corner of radius
r pulls the edge inward by r - sqrt(r^2 - (r-y)^2) at distance y below
the top: at the first line that is ~19 pt, so the top and bottom lines
rendered INSIDE the arc.

Concentricity is only a virtue while the radius is small next to the
card. The radius is now capped at 28 (devices asking for less still get
a truly concentric corner) and the iOS content padding scales with it at
0.45*r, which leaves ~4.6 pt of arc against 12.6 pt of padding at the
cap. The card grows by under 3 pt a side; the compact pill is unchanged.

enricobuehler f6de620f34 fix(client/android): a captured Sony pad's gyro turned the wrong amount
G14/G16 leg 3. This supersedes the nominal constant 0e40b374 shipped, which was
always labelled a stopgap.

Measured on glass 2026-08-07: a DualSense over USB into an Android phone,
streaming to a Linux host, flat and face up, arrived as |accel| = 0.811 g where
1.000 was owed. The parse forwarded the pad's raw i16s verbatim, and raw device
units are not wire units. 0e40b374 rescaled acceleration by the nominal
10000/8192 and deliberately left gyro alone, because a constant provably cannot
fix gyro: the same still average showed this unit's accel calibration is
near-identity (~1% off) while its gyro's emphatically is not — a near-identity
gyro calibration would imply 1024 LSB per deg/s, i.e. ±32 deg/s full scale, which
no controller has. That scale is per unit, and the only thing that knows it is
the pad.

So the client now asks. HidUsbLink grows a GET_REPORT path — EP0, the exact
mirror of the SET_REPORT it already had — and DsCapture reads the pad's IMU
calibration feature report ONCE, while claiming it: 0x05 / 41 B on a DualSense or
Edge, 0x02 / 37 B on a USB DualShock 4. DsDevice.MotionCal then applies
hid-playstation's own arithmetic per axis, which is the same math the host's
contract test (crates/pf-inject/tests/motion_contract.rs, SonyImuCalibration)
reads from the other end: gyro raw × speed_2x × 20 / (|plus−bias| + |minus−bias|),
accel (raw − (plus − range/2)) × 20000 / range. Long arithmetic, because the gyro
multiplier overflows an Int, and clamped, because both are >1 multipliers and a
full-scale flick would otherwise wrap the i16 into a motion in the opposite
direction. Reading the blob also removes acceleration's residual ~1% factory bias
that the nominal constant left behind.

Once at claim and never per report. EP0 is independent of the interrupt endpoints
so the read is safe alongside the reader thread, but a blocking control transfer
in the report path would wreck capture latency, and the calibration is fixed for
the life of the connection anyway. The capture logs the derived resolutions, which
is the discriminator for whether a blob was read at all: a real pad declares ≈16
LSB per deg/s, the fallback reads back as exactly 20.

A pad that refuses, answers short, or declares zeroes (a clone, a broken unit)
keeps today's behaviour per axis — nominal accel, gyro straight through. Nothing
here ever zeroes motion: slightly mis-scaled beats silent.

Not covered. The axis frame is still untouched: this leg puts gravity on Y where
the Apple leg put it on Z, so at least one client's frame is wrong, and settling it
needs the bare-metal Linux reference reading G16 step 1 calls for. Rescaling is
frame-independent, so it stands however that resolves — remapping is not, so it
stays out. Bluetooth's grouped plus/minus layout is not implemented either: this
path is USB-only by construction (Android exposes no raw path to a Classic pad),
and a half-used generalisation would be a latent bug rather than a feature.

Gate: `:kit:compileDebugKotlin` + `:kit:testDebugUnitTest` green, 16 DsDeviceTest
cases run 0 failed, and the five new ones were confirmed present in the JUnit XML
rather than merely compiled. Non-vacuity checked by mutation — perturbing the gyro
conversion fails 6 tests, including all four new ones that assert a number.

On-glass re-verification owed, on the rig that measured the defect (DualSense →
USB → phone → 192.168.1.21): at rest |a| = 1.00 g exactly via ~/gyroscope.py, and
a nominal 90 deg yaw integrating to ~90 deg via ~/integrate.py — the same 90 deg
that read ~62.7 deg before this change.

Three things the Intel Arc measurement showed were wrong or unhelpful in the refusal
path.

The message named NV12 whatever the stream was. A Main 10 session refused over P010
was told about NV12, which sends the reader to look up the wrong format's support.
Both variants now carry the format the driver's own entry reported.

A missing SAMPLED now says what it costs. "does not advertise usage SAMPLED" is
accurate and tells a field reporter nothing: the consequence is that no shader can
read this device's decoded pictures, so the zero-copy path cannot exist on it at all
— which is a different conversation from a device that is merely slower. The line
points at --probe-decode for the driver's own words.

And the probe's second opinion no longer claims to be one. Measured on both vendors,
vkGetPhysicalDeviceImageFormatProperties2 answers "creatable" for combinations the
video-format query rejects — on NVIDIA too, for SAMPLED alone, which is not a legal
video image usage at all. So it does not honour the chained profile list and must not
be read as permission; it is still printed, because otherwise everyone who reads a
refusal asks the question again, but it is labelled as not authority.

Also names the three video ENCODE usage bits, which NVIDIA advertises on decode
pictures and the probe was printing as "unrecognised 0xC000".

Structural, because tuning the transform values was treating a symptom.
A scroll transition derives its phase from the geometry of the view it
wraps, and the entrance was wrapping each card on the OUTSIDE - so it
moved the very thing the transition measures. Every card read as far
from centre for the whole travel, phase pinned at fully receded, and the
centred card only collapsed into its focused look as the entrance ended.
That collapse was the jump; shrinking the offset last round only made it
smaller.

The card builder now hands each caller its own CardEntrance and both the
launcher and the coverflow apply it BENEATH their .scrollTransition. The
transition measures a card that never moves and composes its scale and
rotation on top of the entrance's, so the two can no longer fight - and
the fuller travel is back (34 pt rise) now that the geometry constraint
that forced it down to 16 is gone.

The focused card jumping into its correct state at the end of the
entrance was the entrance's own geometry. The caller's .scrollTransition
reads the geometry of the view underneath the entrance's transforms, so
a card shoved 58 pt down and hinged on its leading edge spent the whole
travel reported as far from centre - phase pinned at fully receded - and
only collapsed to identity as the card came home. That collapse IS the
jump, and it explains why it looked timing-dependent rather than simply
broken.

Now the rotation is about the card's centre (it turns in place instead
of swinging sideways out of position) and the rise is 16 pt, inside the
strip's own vertical slack, so nothing the entrance does moves a card
away from where the scroll view thinks it is. The entrance also waits a
couple of frames for real layout - the GeometryReader's first pass can
report no width, so there is nothing to centre on yet - and the
transaction override from the previous round is gone: it was not the
cause, and nil-ing inherited animation could have made navigation
snappier than intended.

The Intel Arc refusal moved one step down the caps query and stopped again: the
coincide NV12 entry does not advertise SAMPLED. That sentence is punktfunk's, not
the driver's, and the last two times a conclusion was drawn from a sentence of ours
the conclusion was wrong.

So --probe-decode now prints the driver's own answers instead. For every profile the
client can negotiate (H.264 High, H.265 Main and Main 10, AV1 Main 8- and 10-bit) it
asks vkGetPhysicalDeviceVideoFormatPropertiesKHR in six usage combinations — the
three the image pools really create with, plus DPB|DST without sampling, SAMPLED
alone and DST alone, which are what localise a refusal to a half. Each answer is
printed as the driver gave it: format, usage and create flags named AND in hex with
unrecognised bits called out, image type, tiling. A failed query prints its VkResult
rather than vanishing into an empty list.

It goes through pf-vkdecode's own query rather than a copy of it, which meant
splitting query_formats into a physical-device form — the call never needed the
VkDevice the old signature demanded. VideoFormat gains imageType and imageTiling to
carry the whole record; VUID-VkImageCreateInfo-pNext-06811 compares both for
equality, so they were being assumed rather than read.

And because a driver that under-reports usage would be indistinguishable from one
that genuinely lacks it, the probe asks a second, independent question —
vkGetPhysicalDeviceImageFormatProperties2 over the same profile list — and prints it
only where the two disagree. A disagreement is the finding.

No behaviour change to any decode path: derivation reads the same fields it did.

The strip entrance is one animated progress value now, not a Bool behind
per-card .animation modifiers. Those modifiers wrap the caller's card -
INCLUDING its .scrollTransition - so a delayed spring flipping while the
scroll view was still settling captured the transition's own per-frame
phase updates and stranded the centred card half-receded until the next
scroll re-drove it. That was the 'only navigating fixes it' report, and
the race with load speed was the same thing.

CardEntrance is now a ViewModifier + Animatable: it slices its own
window out of one master clock the carousel animates 0 -> 1, so every
transform is a pure function of an interpolated Double and no animation
modifier wraps a card at all. Benign failure mode too - progress
reaching 1 without animating leaves each card at exact identity rather
than stranded. The entrance also moved inside .frame(width:) so a scroll
target's geometry never depends on what its card is doing, and the
non-tvOS branch states its .id explicitly.

One leak remained after that: withAnimation sets its animation on the
whole TRANSACTION, so the scroll view's initial centring still inherited
the 1 s linear clock and the focused card only reached its correct look
as that clock ran out - arriving as a jump. The card subtree now clears
the inherited animation, so its phase lands per frame while the
entrance's own transforms (driven by animatableData, not by the
transaction) keep running.

enricobuehler 0e40b374e7 fix(client/android): DualSense acceleration arrived ~18% short
G16 leg 2. A DualSense over USB to an Android phone, streaming to a Linux host,
flat and face up: |accel| = 0.811 g where 1.000 is owed. Magnitude is
frame-invariant, so this is unambiguous regardless of the separate axis question
below, and it came from a 27-second static average — no sampling error in it.

`DsDevice` said so plainly: "Gyro/accel stay in raw device units". It read the
i16s out of the pad's report and forwarded them verbatim. But raw device units
are not wire units — the wire is fixed at 10000 LSB/g and the pads' native
resolution is the 8192 that hid-playstation calls DS_ACC_RES_PER_G. 8192/10000 =
0.819 predicted against 0.811 measured. Acceleration is now rescaled on both the
DualSense and DualShock 4 parse paths, clamped because the multiplier is >1 and
a real near-full-scale slam would otherwise wrap the i16 into an impossible
acceleration in the opposite direction.

Two things deliberately NOT done.

Gyro is left alone. It is almost certainly low by the same mechanism, but it
cannot be corrected with a nominal constant the way acceleration can: the still
average shows this pad's accel calibration is near-identity (~1% off), while the
gyro's emphatically is not — a near-identity gyro calibration would imply
1024 LSB per deg/s, i.e. ±32 deg/s full scale, which no controller has. Fixing
gyro means reading the pad's calibration feature report and applying its own
numbers, which also removes acceleration's residual 1% bias. `HidUsbLink` can
SET_REPORT but has no GET_REPORT path yet, so that is a real change rather than
a constant, and it is owed.

I tried to pin the gyro factor by integrating the on-glass rotations instead: a
nominal 90 deg yaw integrated to ~88.5 deg through the Apple client (correct)
and ~62.7 deg through Android. Directionally consistent, but the readout samples
at 5 Hz and a ~1 s rotation is badly undersampled, so that ratio is not a
constant anyone should ship. Recorded, not used.

The axis frame is also left alone. This leg puts gravity on Y where the Apple
leg put it on Z, so at least one client's frame is wrong — but Android forwards
the pad's own axis order un-remapped, which makes its reading evidence about the
hardware rather than about us, and resolving it needs the bare-metal reference
reading G16 step 1 calls for. Every bare-metal Linux box was unreachable
(Deck down, HTPC down, .25 is another KVM guest). Rescaling does not touch axis
order, so this fix stands however that resolves.

Gate: `:kit:compileDebugKotlin` and `:kit:testDebugUnitTest` green, JNI libs
built clean at the API-28 floor across 3 ABIs. On-glass re-verification owed:
re-run the at-rest reading and expect 0.99-1.00 g.

Three defects behind an entrance that read as a card sliding up:

- The centred card never rotated. The stagger fans out from an anchor,
  and the anchor was given side 0 = no rotation - but the anchor IS the
  card the eye is on, so the single most visible card only rose. Side is
  never 0 now; every card turns.

- The swing happened while the card was invisible. Opacity shared the
  transform's spring, so the card spent its whole rotation at near-zero
  alpha and only the last few degrees showed. The fade now runs on its
  own 0.22 s curve (a second .animation governs only the modifiers above
  it) while the transform springs over ~0.6 s. The travel is deeper too
  - 0.74 scale, 64 degrees, 58 pt - and the rotation sign now matches the
  coverflow's own recede, so a card unwinds INTO its resting angle
  instead of swinging against it.

- It fired before the art existed. Cards swung in as grey placeholders
  and filled with artwork afterwards. PosterImage reports when a cover
  settles (art loaded, or candidates exhausted), the coverflow counts
  the first few, and GamepadCarousel holds its entrance on a
  contentReady gate - with a 700 ms backstop so a slow or artless
  library still animates.

The strip entrance never ran in the library, for two reasons:

- The trigger was lost. Flipping the state inside onAppear puts the
  change in the SAME transaction as the view's insertion, where SwiftUI
  runs with animations disabled. The launcher got away with it; the
  library's strip mounts late - only once the fetch lands - and lost
  every time. The flip now defers one runloop turn, so it is an ordinary
  animated state change.

- The art snapped in behind it. Covers hard-swapped from grey
  placeholder to image, so even a working entrance was followed by a run
  of cards popping to artwork after the strip had settled. PosterImage
  cross-fades now (the touch grid inherits it).

And the entrance is 3D: a card starts turned away on the drum, small,
low and invisible, then swings flat, grows and rises on an overshooting
spring. Cards left of the anchor hinge on their trailing edge and cards
right of it on their leading one, so the strip FANS OPEN from the cursor
instead of sweeping past it - the same hinge-and-perspective language
the coverflow's own recede speaks, so arriving and scrolling read as one
object. Reduce Motion still drops every bit of travel.

Two more from the on-glass pass:

- The coverflow's store/source chip only showed its background on the
  centred cover. Same mechanism as the tray blur: a card rides a
  scrollTransition that composites it with opacity < 1 and a 3D
  rotation, and a material cannot sample a backdrop through an offscreen
  composite - so the frost stayed blank everywhere except the one card
  sitting at exactly full opacity. The coverflow's chip is a flat wash
  now (StoreBadge gains `solid`), which has no backdrop to sample and
  is therefore simply always there. The touch grid keeps its material -
  its cards carry no transform, so its frost samples fine.

- Host cards and library covers now arrive with the strip instead of
  being there: each card rises out of a fade on a lightly overshooting
  spring, delayed by its distance from the cursor, so the strip
  assembles outward from where the eye already is. Implemented once in
  GamepadCarousel, so the launcher and the coverflow inherit it
  together. Transforms only - snapping, the callers' own
  scrollTransition and the tvOS focus engine are untouched - and Reduce
  Motion drops the travel for a plain unstaggered cross-fade.

enricobuehler 9e9bb9f466 fix(client/apple): acceleration was upside down — measured on glass
G16, first result. A DualSense paired to an iPhone, streaming to a Linux host,
lying flat and face up: hid-playstation decoded z = −0.99 g where a DualSense
owes +1.00. Vector magnitude was 1.006 g, so the scale was already correct —
this is purely direction, and it was wrong for every accelerometer sample the
Apple client has ever sent.

The cause is a convention mismatch, not a sign typo. Apple reports acceleration
as the gravity VECTOR, which points down: a device face-up on a table reads
z = −1. An accelerometer physically measures proper acceleration, and at rest
that is the +1 g normal force pushing UP — which is what a DualSense's report,
and therefore our wire, carries. The two are exact negatives. Both branches were
affected, because `m.acceleration` follows the same Apple convention as the
gravity/userAcceleration split, so reading the "raw vector" was not an escape
from it.

`rotationRate` is a true angular rate and needs no flip. The same session
confirmed that independently: rotating the pad clockwise seen from above
produced a negative yaw, which is correct under the right-hand rule about an
up-pointing Z. That asymmetry — accel wrong, gyro right — is itself evidence for
this diagnosis rather than a blanket frame error, and it is why the fix is three
negations at one site instead of a remap.

The sweep predicted this ("Apple accel plausibly INVERTED — CoreMotion gravity
-1 g vs DS +1 g up at rest") but could not confirm it without hardware. It is
now measured, and the mechanism is confirmed in the code rather than inferred
from the number.

Method, for whoever repeats it: the readout is python-evdev on the host reading
the virtual pad's own motion node, dividing by the axis `resolution` the kernel
publishes, so it prints deg/s and g. That is downstream of the calibration blob
— the same layer a game reads — which is what makes a sign error visible to a
human at all.

Two things this does NOT establish. The host was a KVM guest, so the DualSense
could not be attached natively for a side-by-side reference reading; the test
stands on the DualSense convention being a fixed property of the hardware, which
is decisive for the at-rest sign but weaker for the gyro axis ORDER. And the fix
itself is unverified on glass: confirming it needs a rebuilt client on the
device, so someone should re-run the same at-rest reading and see +1.00.

Gate: `swiftc -parse` clean. A full typecheck needs the gitignored
PunktfunkCore.xcframework assembled first and has not been run.

Round-3 field findings: the pop-in had retreated to the X axis alone -
the one growth still left to safe-area resolution (the landscape side
insets), which settles a beat after insertion, outside any geometry
group and outside the view's own transaction. The scrim now reaches
full-bleed purely by layout: a fixed 80 pt negative-padding overhang on
the outer edge and both sides replaces ignoresSafeArea entirely, so
every axis is deterministic from the first frame (and orientation no
longer changes the gradient's proportions). The mask's strong region
moves to 0.65 to account for the overhang leading the gradient.

And the frost reads black now, not grey: an ink.shade(0.35) wash inside
the mask sinks the material's luminance lift toward the palette's shade
- black on a dark field, palette-honest on a pale one.

Two follow-ups from the second on-glass pass:

- The tray blur's pop-in survived the geometryGroup: the full-bleed
  growth (negative padding + safe-area expansion) rode the push's
  transaction, and safe-area resolution sits outside a geometry group.
  The scrim now pins its own geometry out of any animation - the layer
  fade/slide still carries it, only its SHAPE can never animate. The
  bottom overshoot grows 32 -> 72 pt (the tray sits over scrolling rows
  plus the detail line; the blur influence starts well above the legend
  now) and the mask holds strength longer before dissolving.

- The selected tab pill is a Liquid Glass surface (accent-tinted
  through consoleGlass, material fallback pre-26/tvOS) - the strip
  wears the same material language as the rows below it. The
  matched-geometry travel between pills is unchanged.

Six findings from the on-device pass over #91, all iOS-facing:

- The tray blurs no longer grow into place on a push: the screen layer
  resolves its internal layout (safe-area trays, the scrims' full-bleed)
  in a geometryGroup BEFORE the insertion animates.

- The option band is LINEAR now, not a ring. A ring showed the first
  option waiting to the right of the last one - unreachable, since
  left/right clamps - and on a 2-option ring the unselected item flipped
  sides with every step (the 60/120 Hz row). Positions are fixed, the
  ends are the ends, and A's wrap travels back across the list. Options
  other than the facing one exist only while the drum is moving, so a
  long label never sits under a resting neighbour as overlapping text.

- Toggles (and the pin rows) ride the band too: Off left of On,
  matching the left-off/right-on step semantics.

- The close X is gone from settings, add-host and the library - a
  gamepad UI exits with B. A chromeless cancel button keeps hardware
  Esc and the macOS sheet working, and the library's loading/error/empty
  states gain a zero-size B listener so a controller-only user is never
  trapped where the coverflow (and its B) doesn't exist yet.

- The heading is a real heading: leading-aligned with the 24 pt content
  inset, 24/34 pt (was 20/30), top margin 18/28 (was 10/18) - launcher,
  settings, add-host and library alike. The launcher's hidden-mirror
  chip trick died with the centred title that needed it.

Four reworks from the first palette-era on-glass review, all iOS-facing:

- Surfaces carry the palette now, not just the text on them: ConsoleGlass
  washes every tier (Liquid Glass tint, pre-26 material, tvOS material)
  with ink.glass — the same colour the desktop console fills its panels
  with — and the close buttons move to an ink-aware consoleGlassBackground.
  The pre-26 branch also gains the focus tint it had silently dropped.
  Stray literals follow: ConnectOverlay text rides ink in the console
  takeover, card shadows soften on pale fields, the focused keycap reads
  onAccent. The online pip stays status-green on purpose.

- The header breathes: title top padding 4/10 -> 10/18 plus shared
  header-spacing and title-bottom helpers mapped from the console shell's
  rhythm, applied to the launcher, settings and add-host alike, with the
  add-host close X re-anchored to the title row.

- Settings, Add Host and the Library present IN PLACE on iOS: one
  persistent aurora whose calm is chased (the console's bg_mix), screens
  as transparent layers with the console's 0.26 s ease-out-cubic push/pop,
  an input drop for the transition, and the controller handed off through
  isActive — no more opaque bottom-up covers, no backdrop teardown.
  macOS keeps its sheets, tvOS its focus-engine covers.

- The settings select is a real band: choice rows mount GamepadOptionBand,
  a spring-driven drum (Animatable body, ring-distance wrap, neighbours
  gated by focus and flight) whose retargeting spring accumulates rapid
  steps into one continuous spin. Reduce Motion falls back to a plain
  crossfade; toggles keep the quiet 14 pt slip.

Verified: swift build (macOS), swift build --triple arm64-apple-ios17.0,
swift test 208 passed / 0 failed. On-glass QA still owed: palette sweep on
a pale palette, transition compositing over materials, drum feel on device.

enricobuehler c0f8f051c3 fix(client): the probe printed a device index the env var does not take
--probe-decode printed its DISPLAY position and called it the
PUNKTFUNK_VK_DEVICE value. It is not. pick_device resolves that variable against
the RAW vkEnumeratePhysicalDevices order (setup.rs, `devices.get(i)`) BEFORE any
ranking runs, while the probe sorts discrete-first for readability.

Those two orders disagree precisely on the hardware this flag exists to
diagnose. pick_device's own comment records why the ranking is there: "enumeration
order puts the iGPU FIRST on some hybrids (observed: Ryzen iGPU ahead of an RTX
dGPU)". So on a hybrid laptop the number the probe printed for the iGPU could
well be the number for the dGPU — a diagnostic handing out an actionable value
that selects the other GPU, which is worse than printing none.

Measured on the Arc + RTX 3500 Ada laptop, which is also where the first output
went out with the wrong claim in it: three adapters, and the same Arc iGPU
enumerated TWICE. So AdapterDecode now carries the raw enumeration index,
captured before the sort, and the printer uses it; the "default presenter"
marker stays on the first LISTED entry, because sorted-first is what pick_device
lands on when nothing overrides.

The duplicate is why the trailing hint names PUNKTFUNK_VK_ADAPTER as the safer
knob and admits its limit: two adapters sharing a marketing name cannot be told
apart by it, and a name match resolves to whichever enumerates first. The hint
also states the thing this whole output invites a reader to get wrong — that a
capable GPU in the list does not mean the decoder will use it, because Vulkan
Video decodes on the presenter's device and PUNKTFUNK_DECODER does not move the
presenter.

enricobuehler 43e713ecca fix(client): the probe now accounts for every bit it prints
First hardware run of --probe-decode, on the RTX 5070 Ti:

    driver decode ops:   H.264, H.265, AV1 (0xF)

Three names, four bits. 0xF is H.264|H.265|AV1|VP9 — bit 3 is
VK_VIDEO_CODEC_OPERATION_DECODE_VP9_BIT_KHR, a real decode operation this
client has no rung for, so the name table stopped short of it and the line
looked complete while silently dropping a codec the driver had advertised.

That is the exact failure this flag exists to prevent. The whole point of
--probe-decode is that a reader can trust the words to cover the number; a mask
with an unexplained bit asks them to trust it instead. VP9 is now named (marked
as having no punktfunk rung, because advertising it as decodable would be its
own lie), and any bit beyond the four we know prints as "unrecognised bits
0x…" rather than vanishing — so the next codec Khronos adds shows up as an
unknown rather than as nothing at all.

enricobuehler 4834c2ee51 fix(host/pads): DualShock 4 gyro ran 40× fast, and no pad ever stopped turning
Phase 1 of the gyro program (design/gyro-program.md, G1-G5) — the five
correctness fixes under it. Gyro aim integrates angular velocity over time, so
each of these is not a cosmetic wrongness: a wrong scale is every rotation being
the wrong size, a wrong clock is every rotation being integrated against a
fictional dt, and a stale sample is rotation that never happened.

G1 — the DualShock 4 calibration blob. A Sony pad does not assume a motion
scale, it reads one out of a fixed calibration feature report. Ours declared
0.5 LSB per °/s and 8192 LSB/g while the wire delivers 20 and 10000, so every
DS4-type session decoded gyro 40× too fast and acceleration 1.22× hot — since
the backend shipped. The blob now states the wire's own units (the DualSense
blob's numbers, deliberately: both pads consume the identical wire sample). Its
interleaved per-axis order is NOT a bug and stays: the virtual pad declares
BUS_USB, where interleaved is the correct layout; grouped is Bluetooth's.

The same blob lives a second time in the UMDF driver, which is a separate WDK
workspace that cannot depend on pf-inject — one wrong table in two files, where
fixing one reads as fixing it. Both are fixed, and the DS4 feature reports now
live in dualshock4_proto beside the DualSense's rather than in the Linux
backend, so there is one canonical copy to point at.

Field hosts keep the old blob until they update the host package.

G2 — the gate that would have caught it. Nothing pinned any backend's
declaration against the wire, so tests/motion_contract.rs now applies the
CONSUMER's arithmetic (the kernel's, and SDL's, which differ) to each backend
and asserts the result lands back on the wire constants — for the DualSense and
DS4 blobs, and for the Deck and Switch Pro rescales. It also parses the driver's
Rust source and re-derives the units from THAT, so the two copies cannot drift.
Verified non-vacuous both ways: re-introducing the old blob fails with "declares
a fractional 32/64 LSB per °/s", and reverting only the driver's copy fails with
"the UMDF driver's DS4_FEATURE_CALIBRATION has drifted from pf-inject's".

The wire units themselves move to punktfunk_core::input::gamepad, referenced by
the client's capture scale, the Deck/Switch rescales, and the probe — whose
at-rest vector said 16384 (a driver's number, not the wire's) and now says 1 g.

G3 — real sensor clocks. The DualSense advanced its sensor timestamp by +1 raw
unit per report (0.33 µs — a frozen clock) and the DS4 by a flat +188 (~1 ms)
regardless of the real 4-8 ms cadence. Anything integrating rate × dt off that
field got nonsense. All four backends now stamp elapsed monotonic time in their
own units via a shared SensorClock, anchored to the pad's first report so an
irregular publish loop cannot make it drift, and truncated to the field width —
which reproduces the wrap real hardware does.

G4 — motion is level-triggered and had no watchdog. merge_frame preserves the
last sample and the heartbeat re-emits it, so a feed that stops leaves the pad
rotating forever — and with G3's honest clock, at a dt that keeps growing.
Rumble and the pen plane each have an idle timeout; motion now has one too, at
100 ms. Angular velocity only: acceleration is kept, because gravity is
legitimately persistent and blanking it reads as free-fall. The SDL client
parks its gyro at zero when a slot closes, which is the case we can flush
rather than wait out. (The Apple half of this rides in PR #88.)

G5 — a pad returning inside the 300 ms replug grace keeps the same device and
skips the create path, so a different controller inherits the previous one's
touch contact and rotation — and a pad with no gyro never sends a sample to
correct it. sweep() now reports re-claims separately from drops, and the manager
clears the rich plane on one. Rich fields only: rumble and hidout dedup
deliberately survive a removal.

Gates (Linux, CI image): fmt, build, clippy --all-targets -D warnings over
pf-inject/punktfunk-core/punktfunk-probe/pf-client-core, and the test suites —
110 pf-inject unit + 6 contract + 29 pf-client-core gamepad, all green.

Field report from an Intel Arc + NVIDIA laptop: pinning the Vulkan rung on the Arc
iGPU silently produced D3D11VA, and there was no way to tell whether the build had
tried at all. That ambiguity was ours, in three places.

The "unavailable" log printed three of the FIVE conjuncts that gate Vulkan Video.
A device with 1.3, the features and a decode queue family — but no codec extension
— logged dev_is_13=true features_ok=true decode_family=true next to the word
"unavailable" and named nothing actionable. It now prints all five, plus which
base extensions are missing, which codec extensions are present, the decode
family's own advertised codec operations, and the device name and vendor. It also
no longer says "VAAPI/software" on Windows, where the rung below is D3D11VA.

The native-vulkan PIN refusal logged `video_decode` alone. On a device that
decodes something but not THIS codec, that reads as a contradiction: refused, yet
video_decode=true. It now carries the caps mask and the codec bit that was wanted,
so "your GPU can't" is distinguishable from "we asked for the wrong thing" — only
the second is our bug.

And `--probe-decode` is new: per-adapter Vulkan Video capability with no session,
no surface and no logical device. For each GPU it answers usable yes/no, the
driver's own decode ops, the extensions, and — when the answer is no — which
conjunct failed, in words. Separate from --list-adapters, which the desktop shells
parse line-by-line for their GPU picker and which therefore keeps printing bare
names.

The listing is ordered like pick_device (discrete first) and marks entry 0 as the
default presenter, because that ordering is very likely the reporter's actual
answer: pick_device ranks DISCRETE_GPU above INTEGRATED_GPU, Vulkan Video decodes
on the PRESENTER's device by design (that is what makes it zero-copy), and
PUNKTFUNK_DECODER does not move the presenter. So on a hybrid laptop, pinning the
decoder while the dGPU presents probes the wrong GPU entirely —
PUNKTFUNK_VK_DEVICE=<index> is the knob that moves it, and the index printed is
that value.

To keep the probe honest, VIDEO_BASE and VIDEO_CODECS moved to module scope and
the five-way AND became video_decode_gate(), called by both the probe and device
creation. A probe holding its own copy of the rule is one that eventually reports
a capability the session then refuses — which reads to everyone as a decoder bug
rather than a probe bug.

Gates: fmt clean; clippy -D warnings over punktfunk-client-session and
pf-presenter. The Linux container was unavailable (the host's disk filled and took
the docker daemon with it), so this ran on the macOS host target only — the
container leg is owed, and CI covers it on the PR.

enricobuehler f06b3d9d04 feat(console): the console answers a mouse and a finger, and host cards get a menu
Two gaps, both found on the shared Linux/Windows console UI.

**The settings tabs only moved for a gamepad.** They were bound to the shoulder
buttons and to PgUp/PgDn, and the legend spells PgUp/PgDn out only when NO pad is
attached — so with a controller plugged in a keyboard user had nothing to find,
and a mouse or a touchscreen could not change section at all.

The root cause was wider than the strip: `SkiaOverlay::handle_event` matched only
`KeyDown` and `TextInput`, so every mouse button, wheel and touch contact fell
past the console into the run loop, which routes pointer input exclusively at
`stream.capture` — `None` while you are browsing. Nothing in the console had ever
been clickable. Making just the pills answer would not have helped either: the
settings screen is opened with X from home, so a mouse could not reach it.

So the console gets a real pointer path:

- `Overlay::handle_pointer` carries mouse/touch in SWAPCHAIN PIXELS. The run loop
  converts (it owns the window, hence the display scale, and mouse coordinates are
  logical while fingers are normalised); the console then hit-tests the very rects
  it drew last frame. Only DIRECT touch devices are offered — an indirect trackpad
  already drives the mouse.
- Widgets act on the PRESS, not the release. The list and both carousels scroll the
  focused item toward the centre, so what you pressed has slid out from under your
  finger by the time it lifts; press-to-act has no such race and there is no drag
  gesture to compete with.
- The hint bar became the pointer's button bar. It is already the console's only
  on-screen statement of what the face buttons do, and a pointer has none — so its
  Confirm/Back/Secondary/Tertiary pills are clickable on every screen, which is what
  puts Settings and Library within reach of a mouse at all.
- Tab / Shift+Tab change section; PgUp/PgDn still do, and the keyboard legend now
  reads "Tab".
- Right-click is Back everywhere, EXCEPT at the root: B there quits the launcher and
  a right-click is far easier to fire by accident. Quitting stays explicit.

**Host cards had no menu.** Every other client hangs Wake / Copy link / Edit /
Forget off a host card; the console could add a host and connect to one, and that
was all — so a renamed machine or a fat-fingered address stayed wrong forever
unless you opened a desktop shell. UP on a saved tile now opens that host's menu,
the same gesture the Android console uses, on the one direction a horizontal
carousel leaves free.

- `ConsoleCmd::UpdateHost` edits the stored host IN PLACE. Removing and re-adding
  would silently drop the fingerprint, the learned MAC, the pinned cards and the
  profile binding — that is a rename, not a re-pair.
- `ConsoleCmd::ForgetHost` drops it; if it is still advertising it returns as a
  discovered, unpaired row, which is the honest state.
- Forget arms on the first press and fires on the second. The other clients forget
  outright; a console is driven by a thumbstick from across a room.
- A pinned profile card offers only Unpin. It is a shortcut, not a second host, and
  offering to forget the host from it would blur exactly the distinction a pin draws.
- "Edit…" REPLACES the menu on the stack rather than stacking over it, so Back from
  the editor doesn't land on a menu describing the host as it was before the edit.

Verified in the pf-lxcheck2 container (this crate compiles to nothing on macOS —
a bare `cargo check` there is vacuous): plain build and `clippy --all-targets`
clean under `-D warnings`, 72 tests pass. Seven are new, and cover the reported
bug directly — a press on a pill selects that tab, and each tab still keeps its
own cursor when a pointer is what switched it.

Opt-in "Gyro from this phone" (gyro_on_phone, off by default): this
device's IMU sources wire pad 0's motion while that pad is a controller
with no motion source of its own. On Android that gate is exact — the only
pads that forward motion are the capture links (USB DualSense / SC2,
claimed as ExternalPads), so the mirror stands down per sample whenever
GamepadRouter.padHasOwnMotion(0) says a capture link holds the index, and
sends nothing while pad 0 has no slot at all (motion never creates a host
pad). "Rumble on this phone"'s sibling, data flowing the other way: same
read-once-at-attach settings plumbing, same hardware-gated rows in the
touch and controller settings (a TV box has no gyroscope to mirror from).

DeviceGyro registers TYPE_GYROSCOPE + TYPE_ACCELEROMETER at ~200 Hz on a
dedicated HandlerThread with batching disabled (maxReportLatencyUs = 0 —
batching is poison for gyro aim), converts with the wire contract shared
with pf-client-core (rad/s → 20 LSB/°·s, m/s² → g → 10000 LSB/g; Android's
accelerometer already reads specific force, the DualSense report's own
convention), and rotates each sample from the natural-portrait sensor
frame into the controller frame by display rotation — a phone clipped
landscape yaws when the player yaws instead of rolling. The remap matrix
and unit constants are pinned by DeviceGyroTest.

A stand-down edge (capture link claims pad 0, or session teardown) sends
one zero-gyro sample so the host's virtual pad never keeps integrating an
angular velocity this device stopped producing — the gyro sweep's
stale-rotation latch, avoided by construction here.

enricobuehler 1f54b75c5c feat(client/apple): the phone's gyro can speak for a gyro-less pad
Opt-in "Gyro from this device" (DefaultsKey.gyroFromDevice, off by default,
iOS only): while player 1's forwarded controller reports no rotation rate of
its own — no GCMotion, or the gravity-only motion an Xbox pad exposes — this
device's IMU sources pad 0's wire motion instead. The rumble-on-device
mirror's sibling, data flowing the other way: same session-scoped
UserDefaults read, same hardware-gated settings rows, same pad-0 rule.

DeviceGyro wraps CMDeviceMotion at the ~100 Hz CoreMotion ceiling on a
dedicated serial queue (not main — the controller path's main-queue delivery
is a known jitter source), converts with the shared GamepadWire constants,
and rotates each sample from the device's portrait frame into the controller
frame by interface orientation, so a phone clipped landscape yaws when the
player yaws instead of rolling. The remap matrix is derived and pinned by
DeviceGyroRemapTests.

GamepadCapture owns engage/stand-down (reconcile, suspend/resume, stop), and
suppresses pad 0's controller-motion forwarding while the mirror runs — two
writers on one pad's motion state would fight, and the accel-only stream
would stomp the mirror's gyro with zeros.

Also fixes the stale-motion latch from the gyro sweep on the controller
path: flush now parks motion at zero (keeping the last accel, so gravity
doesn't become free-fall), and the mirror's stop sends the same closing
zero. The host holds motion as state and re-emits it — a nonzero angular
velocity left behind read as endless rotation for as long as an overlay
(Control Center pull-down) kept the app inactive.
