enricobuehler	ee61e8c9ba	fix(clients/pads): the phone mirror never needed the controller path's frame change ... 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.	2026-08-07 21:28:13 +02:00
enricobuehler	7a4cdac5b7	fix(client/android): a Bluetooth pad's gyro obeys the same reachability gate as the rest ... 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.	2026-08-07 20:18:39 +02:00

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.	2026-08-07 20:12:39 +02:00
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.	2026-08-07 20:11:28 +02:00
enricobuehler	1eab4b6626	fix(client/apple): the phone-gyro mirror was left on the old motion convention ... 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.	2026-08-07 19:34:22 +02:00
enricobuehler	0170da2a5f	fix(client/apple): stop dropping rotation, and stop inventing it ... 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	d996449a82	fix(host/pads): a virtual pad at rest said it was in free fall ... G14, unblocked by the frame measurement in efb7f991 — the plan deliberately left this one alone until the up axis was known, on the grounds that a confidently wrong constant would be worse than an obviously wrong zero. It is known now. A virtual DualSense, DualShock 4 or Steam Deck that had received no motion reported acceleration `[0, 0, 0]`. That is not "no data": zero proper acceleration means free fall, which is a definite claim about the physical world and one that is never true of a controller sitting on a desk or held in someone's hands — both read 1 g up. Anything that interprets the accelerometer gets a confident wrong answer rather than a boring right one. It is worst exactly where it is least visible. A pad with no gyro at all — an X-Box controller forwarded as a DualSense, which is what "Automatic" does for anything not Sony or Valve — never sends motion, so it sits on that neutral for the entire session, telling every game that reads it that the controller is falling. `switch_proto` has always done this correctly on its own up axis, which is what made the gap visible in the first place. Which axis, and why it took a measurement. The wire is a unit passthrough into the virtual pad's report, so the wire's up axis is the pad's own, and on 2026-08-07 a real DualSense read over raw HID put `+0.997 g` on report axis 1 at rest, in a frame pinned the same session as (Right, Up, Backward). So `MOTION_NEUTRAL_ACCEL` is `[0, 10000, 0]` — NOT the z-up the notes had assumed from `switch_proto`'s documentation, which is why guessing would have shipped a backend confidently disagreeing with the hardware. The constant lives in punktfunk-core beside the units it is expressed in, and every backend derives from it rather than restating it. The Deck's neutral in particular goes through `steam_remap::motion_wire_to_deck`, the same rescale a real sample takes, so the neutral and the live path can never end up with two opinions about what 1 g is — its `hid-steam` resolution stays in exactly one place. The DS4 needs no separate change: it reuses `DsState`. `switch_proto` is deliberately NOT touched, and the test says so. It is a different device on a different driver, its up axis is its own, and nobody has measured its frame — aligning it to the DualSense for consistency would be the same unmeasured guess this commit exists to avoid, just in the other direction. Non-vacuity proven both ways rather than assumed. Moving the up axis to slot 2 (the old z-up assumption) fails on the wire constant itself, which is what makes the measurement load-bearing rather than decorative; reverting both neutrals to `[0, 0, 0]` fails on the DualSense assertion with the message naming the defect. Each backend is checked in ITS OWN units, because hard-coding "1 g" three times is how the halves of a unit contract drift apart. Gate (Linux CI image): fmt, build, `clippy --locked --all-targets -D warnings` across punktfunk-core / pf-inject / pf-client-core, and both test suites — green, with `Running tests/motion_contract.rs` and the new case's own `... ok` line observed in the log rather than inferred from a green exit (`cargo test` stops after the first failing binary, so a green-looking run can mean the contract test never executed at all).	2026-08-07 19:07:30 +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.	2026-08-07 18:41:54 +02:00

enricobuehler	eb9203b115	fix(client/settings): a byte order mark stops silently erasing every setting ... `Set-Content -Encoding UTF8` writes a UTF-8 BOM, and every Windows how-to reaches for it, so `%APPDATA%\punktfunk\client-windows-settings.json` edited from a shell arrives with `EF BB BF` in front of the `{`. serde_json rejects that at byte 0 — correctly, JSON has no BOM — and `.and_then(|s| serde_json::from_str(&s).ok())` turned the refusal into `Default`. Every setting in the file, gone, with the file plainly correct on screen and not one word anywhere about why. Cost an hour on 08-07: a `codec: "av1"` edit was ignored and the client negotiated HEVC. The obvious suspects — the negotiation, the caps, the host — were all working exactly as designed. So the mark is stripped, which is what every other JSON consumer on Windows does. But the BOM is only the instance; the bug is the `.ok()`, which hides a trailing comma, a truncated write and a hand-edit typo just as completely. Those now cost one `warn!` naming the file and serde's own line and column. A file that cannot be READ at all is reported too, and for the same reason: PowerShell's `-Encoding Unicode` writes UTF-16LE, `read_to_string` rejects it as invalid UTF-8, and that lands in exactly the same hole. The RESULT is deliberately unchanged — `Default`, never an error. Nothing about streaming may hinge on a settings file being readable, and refusing to start because one is malformed would be a worse failure than the one being fixed. A missing file stays silent, because that is just first run. All three of this client's JSON stores share the loader, because all three had the identical line: the settings file, the known-hosts store (where a BOM silently unpairs every host) and the profiles catalog.	2026-08-07 17:45:38 +02:00
enricobuehler	32ff93199f	fix(client/video): a damaged AV1 frame stops killing the whole client ... The software rung aborted the process — not the session, the process — the first time a 4K AV1 stream lost a frame. Reproduced on .21 twice on 08-07, `SIGABRT` a few hundred milliseconds after "first frame decoded". It was never about 4K, and it was never our bitstream. rav1d 1.1.0 kills the process on ANY decode error while it holds a single frame context. `rav1d_submit_frame`'s `c.fc.len() == 1` branch calls `rav1d_decode_frame` inline; that always finishes in `rav1d_decode_frame_exit`, which does an unconditional `mem::take(&mut f.frame_hdr)` (decode.rs:4873); and then, only if the decode returned `Err`, the same branch re-enters a local `on_error` whose first act is `f.frame_hdr.as_ref().unwrap()` (decode.rs:4997) — on the `None` the teardown just left. The panic unwinds into `dav1d_send_data`, which is `extern "C"`, so it is `panic_cannot_unwind` → `abort()`: no `catch_unwind` at our call site, no rung demotion and no `NoSoftwareRung` refusal can catch it. The same code is in upstream `main` today, and 1.1.0 is the newest release, so there is no version to bump to. 4K was only where an error first HAPPENED. The CPU rung cannot keep up at 3840x2160 (35-39 fps against a 60 fps stream), so the receive backlog stopped draining, `pump::data` flushed it and jumped to live, and the next AU referenced frames nobody had decoded. libdav1d gives the identical verdict on the identical capture — 13 frames, then "Invalid data found when processing input" — and simply carries on. At 1080p the rung keeps up, nothing is ever flushed, no AU is ever damaged, and the same code ran for years without anybody seeing this. So the fix is to stop asking rav1d for the configuration whose error path is broken. `c.fc.len() > 1` never calls `rav1d_decode_frame` at all: it hands the frame to `rav1d_task_frame_init` and errors come back through `cached_error` / `task_thread.retval` as ordinary `EINVAL`s, which the pump already answers with a keyframe request. Measured, against the captured 4K stream: n_threads=8 max_frame_delay=1 -> n_fc=1 -> ABORT n_threads=1 max_frame_delay=1 -> n_fc=1 -> ABORT n_threads=1 max_frame_delay=2 -> n_fc=1 -> ABORT <- proves the rule n_threads=8 max_frame_delay=2 -> n_fc=2 -> 13 pictures, EINVAL, survives n_threads=8 max_frame_delay=0 -> n_fc=3 -> survives The third row is why `n_threads` grows a floor of two as well as the delay: `n_fc` is `min(max_frame_delay, n_threads)`, so one decode thread silently puts the whole thing back on the aborting path. That row is also what rules out the theory this investigation started with — pinning threads to 1 was the suspected trigger, and it makes things WORSE, so the tile workers are innocent and the single frame context is the entire defect. Two frame contexts would normally cost a frame of latency, and this does not, because `decode` now drains PAST the first `EAGAIN`. `rav1d_get_picture` only reaches its blocking `drain_picture` on a call whose own `drain` flag is already set, and that flag is set by the PREVIOUS `get_picture` and cleared by every `send_data` that carried bytes — so the first `EAGAIN` after a send does not mean "no picture for this AU", it means "ask again", and this AU's frame comes out of the second call. Stopping at the first `None` is what a single-frame-context reading of dav1d's API teaches, and it would have put the pipeline two frames behind while looking perfectly healthy. Measured over 14 temporal units at `n_fc = 2`: stopping at the first `None` produces nothing at all for units 0 and 1; draining past it produces one frame per unit from unit 0, at 20-42 ms per unit against `n_fc = 1`'s 21-53 ms. Not a trade — same cadence, slightly faster, because the tile workers overlap the drain. `Av1Software::new` then asks rav1d itself, through `dav1d_get_frame_delay`, what those settings actually bought, and refuses to open a decoder that would run with one frame context. That is not a restatement of the arithmetic: it is `get_num_threads`' own answer, so it stays right if rav1d's derivation changes. It is there because the failure it guards is uniquely quiet — an edit that reinstates `n_fc = 1` costs nothing at build time, nothing in the tests and nothing on a clean link, and then kills the client the first time a frame arrives damaged. Losing the rung is recoverable; `abort()` is not. On glass, .21, 35-second sessions, `PUNKTFUNK_DECODER=software`: 4K60 AV1 before: SIGABRT on the second frame, every run after: exit 0, 0 panics, 35-39 fps, 1204 frames, decode_failed=0, and 13 decode errors recovered from across 17 backlog flushes — the exact condition that used to abort, survived thirteen times in one session 1080p AV1 after: 40 fps, decode p50 2.2 ms (2.1 ms before the change) What this does NOT buy: rav1d has other `unwrap()`s, and because its whole public surface is dav1d's `extern "C"` ABI — every internal `rav1d_*` entry point is `pub(crate)` — no in-process guard can turn one of them into anything but an abort. This removes the one we hit and can prove; it does not make the CPU rung panic-proof, and the evidence table says so. Reported upstream with a self-contained reproducer: the in-tree `test-25fps.ivf.av1` vector with one temporal unit dropped aborts rav1d at `n_fc = 1`, survives at `n_fc = 2`, and libdav1d decodes it with 145 error reports and no crash.	2026-08-07 17:45:21 +02:00
enricobuehler	0ee690f8bc	fix(client/hevc): the DPB we demanded was the level's ceiling, not the stream's need ... A punktfunk client streaming HEVC from .21 (RTX 5070 Ti) refused every access unit with "stream needs 17 DPB slots, device caps at 16", flushed, waited for an IRAP, got a fresh IDR that needed 17 too, exhausted the decode ladder and reconnected with HEVC excluded. On a build with no software HEVC decoder — there is no permissively licensed one — that is not a slower path, it is losing the codec. The host was blameless. Reading the SPS it actually emitted: general_level_idc 153 (L5.1 High, which NVENC autoselects at hevcConfig.level = 0 because a 130 Mbps target does not fit L5.0's 100 Mbps ceiling) and sps_max_dec_pic_buffering_minus1 = 5 — six pictures, RFI_DPB references plus the current one. Six, at every resolution. That is already the minimum the encoder can honestly declare, and the only host-side lever, the level, cannot be lowered without signalling a bitrate the stream exceeds. There was nothing to fix there. dpb_limit was reading equation A-2 instead. A-2 is a CEILING on what an SPS may signal — 7.4.3.2.1 constrains sps_max_dec_pic_buffering_minus1 to 0..=MaxDpbSize-1 — not a statement of what a stream needs, and it branches on picture size against the LEVEL's MaxLumaPs. At 1080p the coded 1920x1088 = 2 088 960 luma samples fall under MaxLumaPs(L5.1) >> 2 = 2 228 224, taking the first branch for min(4 * MaxDpbPicBuf, 16) = 16. max(A-2, buffering) then reported 16 where the stream had asked for 6, the backends added one slot for the picture in flight, and 17 is one more than NVIDIA's maxDpbSlots. A resolution sweep on the box drew A-2's branch table exactly, and it is the two commonest streaming resolutions that lost the codec: 720p 1280x720 = 921 600 branch 1 -> 16 frames, 17 slots 82 refusals, HEVC dropped 1080p 1920x1088 = 2 088 960 branch 1 -> 16 frames, 17 slots 41 refusals, HEVC dropped 1440p 2560x1440 = 3 686 400 branch 2 -> 12 frames, 13 slots clean 4K 3840x2176 = 8 355 840 else -> 6 frames, 7 slots clean, decode 1.9 ms One host, one level, one six-picture requirement. Only which branch the picture size landed in decided whether HEVC worked. That is also why this hid for so long: 4K was the resolution it was exercised at, and 4K is the one size that falls through to the honest answer. H.264 escaped for an unrelated reason — its own level-derived ceiling happened to land at 13 for 1080p L5.0 and 5 for 4K L5.2 — but it is the same shape of derivation and would fail the same way if NVENC ever picked a higher level for a smaller picture. So dpb_limit now returns the stream's own sps_max_dec_pic_buffering_minus1 + 1, capped at 16. That is not a workaround, it is what the number means: it is exactly the bound C.5.2.2's fullness clause bumps against, and A.4.1 bounds the total RPS entries by the same value, so `buffering` pictures hold `buffering - 1` references plus the current one with nothing left over. The max() that produced the 16 was written to be generous to malformed streams — "storing their pictures beats erroring the AU" — but it never did that either. Dpb::needs_bumping (C.5.2.2) already keys on the signalled buffering, not on max_num_pics, so a stream referencing more pictures than it declared was ALREADY being bumped below its own declared depth before every store. The widened limit bought no tolerance at all; all it ever did was over-allocate hardware surfaces, by ten pictures per session at 1080p, and on NVIDIA take HEVC away entirely. The fix moves 720p and 1080p onto the pool shape 4K has been running in the field all along (7 slots, 6 references), so it is not a new operating point — it is the one already proven. max_active_references drops from 15 to 6, still above the 5 an RFI_DPB stream can name. The per-AU level gate in pf-vkdecode reads plan.picture.level_idc directly, so dropping A-2 out of NegotiationInfo costs no sensitivity to a mid-stream level change. Two regression tests pin the arithmetic from both ends, because either end drifting back reproduces this: - h265: the field SPS synthesized byte for byte on the fields that matter must plan 6 frames / 7 slots, all four resolutions must agree because the stream does, and every depth the envelope gate admits must leave room for the picture in flight. The one honest residue is pinned too and deliberately left refusing: A.4 does let a conforming stream declare a full 16-picture DPB, and 17 slots genuinely do not fit 16, so that stream is still refused rather than decoded with too few slots and silently corrupted references. - pf-encode: RFI_DPB + 2 <= 16, guarding the producer end. RFI is a real latency win and this does not cap it at today's value — there are nine slots of headroom — it just stops it being raised past the point where clients can no longer decode us at all.	2026-08-07 17:34:17 +02:00
enricobuehler	6348334eff	docs(client/video): the evidence table stops saying AV1 never decoded ... Two of its notes became false the moment the host stopped truncating AV1. native D3D11VA / AV1 said "NEVER decoded a frame on any hardware". It has now decoded 4K60 on an RTX 3500 Ada — and the same run is why the note matters: its warn line named the rung as unproven moments before it failed 72 access units running with "reference picture N holds no DPB slot". That was the host shipping half of every frame, not the rung, so the M7 wiring was right all along. It stays UNVERIFIED regardless. `verified` gates `native_rung_admitted` — whether `auto` may pick this rung ahead of Vulkan Video — and one 25-second session with no frame-hash parity and no soak does not buy that. Promoting it wants a deliberate gpu_parity-style run. The note now says what is true instead of what is convenient. software / AV1 said rav1d had "CPU unit tests only". rav1d has now run on glass: 1080p AV1 decodes, and 4K ABORTS THE PROCESS. It takes an internal error path and panics inside its own on_error (rav1d 1.1.0 decode.rs:4997, unwrap on a None frame header); the panic crosses the extern "C" boundary in dav1d_send_data, so it is panic_cannot_unwind and no rung demotion or NoSoftwareRung refusal can catch it. libdav1d decodes the same 4K stream 715/715, so this is rav1d's own defect and is recorded where the next person to reach that rung will see it.	2026-08-07 17:06:35 +02:00
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.	2026-08-07 17:02:04 +02:00
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.	2026-08-07 16:55:03 +02:00
enricobuehler	ebc2f1cf92	feat(host/audio): the minted microphone returns to tier-0 — pitch-true ...

The octave-low voice was the driver DEFAULT endpoints disagreeing (stereo render vs mono capture), never a raw-crossing design. The user called the wrong verdict — the pad program 4ch success was the counter-evidence that reopened the case.	2026-08-07 16:53:48 +02:00
enricobuehler	c16e07d746	fix(encode/nvenc): AV1 stops shipping half a frame ... Every 4K AV1 frame this host encoded reached the wire truncated to its first tile, and had since AV1 was wired up. Measured on .21 (RTX 5070 Ti, 4K60, split AUTO): each access unit carried a frame header declaring two tile rows and a single Tile Group OBU with tg_start = tg_end = 0, so libdav1d rejected 835 of 836 AUs with "Error parsing frame header". NVIDIA's hardware decoder accepts the truncated stream, which is why native Vulkan Video looked healthy at 60 fps while both conformant software decoders — rav1d in-tree and libdav1d out-of-tree — refused every frame and clients fell to a black screen. The two halves of sub-frame readback are armed by different conditions. build_init_params arms the WRITER (enableSubFrameWrite + reportSliceOffsets) from subframe_on alone; the chunked READER additionally requires slices >= 2, and resolve_slices returns 1 for AV1 unconditionally — before the PUNKTFUNK_NVENC_SLICES override is even read, because AV1 partitions via tiles rather than slices. So an AV1 session asked the driver to publish its output tile by tile and then took only the first tile with one blocking lock_bitstream. resolve_split_subframe — the one arbitration point both direct-SDK backends already call — now disarms sub-frame for AV1 and returns split_mode untouched, so AV1 keeps every engine split encode gives it. Arming the reader instead is not a drop-in alternative: poll_chunk cuts at bitstreamSizeInBytes on the reasoning that "slices are contiguous Annex-B", which AV1's OBUs are not. With sub-frame disarmed and split still AUTO, the same session decodes 654/654 frames clean through libdav1d. The test that pinned this as correct (av1_untouched, "both features are legal together") is replaced by one that pins the disarm, and by one that checks the reader's gate against the writer's — the comparison nothing made. The Linux latch comment claiming the two "can't disagree" is corrected; that claim is what made this invisible.	2026-08-07 16:50:17 +02:00
enricobuehler	52cd42e911	fix(host/audio): capture endpoints get the device format only ... Live bisect on a fresh endpoint: the mix/host format keys are RENDER-engine properties — stamped onto a capture endpoint they broke its shared-mode graph (IsFormatSupported reported 2ch/48k OK while Initialize failed 0x88890008 on a once-stamped fresh endpoint; unstamped it opened fine, S3).

enricobuehler	5c4969fd6b	fix(client/pads): the gyro cut-off asked about the session, not the pad ... Supersedes the check 77797a9e shipped an hour ago. The suppression, the log-once, and the "unknown must not suppress" rule all stand; the field it reads does not. 77797a9e read `Welcome.gamepad` — the backend the host resolved for the SESSION — and stopped sending motion when it had no motion plane. But the host does not build pads from that. It builds each virtual device from that pad's own `GamepadArrival` (`Pads::set_kind`) and falls back to the session default only for a pad that never declares one, which is precisely why `declared_kind` exists and why its doc comment says an explicit setting has to be re-declared per pad. So the check had a false negative, and it is an ordinary living-room setup. Under "Automatic" the Hello carries the ACTIVE pad's kind (`auto_pref`), so a couch with an X-Box pad on slot 0 and a DualSense on slot 1 echoes Xbox360 — while the host, reading pad 1's arrival, builds it a DualSense with a working motion plane. The old check read the echo, saw no motion plane, and killed pad 1's gyro. That is the exact failure 77797a9e's own commit message names as the worse of the two ("a false negative kills working motion"), introduced by the fix for the other one. The question is per pad, so the slot now carries what it declared, beside the physical `pref` it already held. The two are deliberately separate fields answering different questions: `pref` is the controller in the user's hands, which is what the local feedback paths must keep reading, and `declared` is the one the host is pretending to have. Three facts decide the predicate, and they are written out in `pad_motion_reaches` rather than at the call site because all three clients need the same reasoning: - the echo is not this pad's answer when the pad declared something else; - the host FOLDS what it cannot build — a Switch Pro on Windows, any UHID backend on a host whose /dev/uhid is unusable — and nothing client-side can predict it; - but the echo IS one observed sample of that fold, for the kind the Hello asked about, so it is authoritative for a pad that declared exactly that. Hence: trust the echo when declared == asked, else fall back to the declaration. That keeps both motivating cases — a generic pad under Automatic (declares X-Box 360, suppressed, the sweep's H5c) and an explicit Switch Pro folded to X-Box 360 by a Windows host (declared == asked, so the echo catches it, H5d) — where either field alone gets one of them wrong. `requested_gamepad` is kept on the client next to `resolved_gamepad` for this: the pair is what makes the echo usable per pad, and a lone field would only tempt the next reader back into the session-level question. The residual gap is a pad whose declared kind differs from the session's AND gets folded: we keep sending and the host keeps dropping. That is the direction to be wrong in, and it is what the session-level check was worth in the first place — wasted datagrams, not a dead gyro. Non-vacuity proven both directions rather than assumed. Reverting to `resolved.has_motion()` fails on the mixed-pad row; reverting to `declared.has_motion()` (no echo at all) fails on the Switch-Pro-on-Windows row. Each case in the table is a session someone can actually sit down to, and the comment on each says which of the three inputs decides it. Gate (Linux CI image, pf-lxcheck2): fmt, `build -p punktfunk-core`, `build -p pf-client-core`, `clippy --locked --all-targets -D warnings`, and both test suites — green, with the new case observed in the run's own `... ok` line rather than inferred from a green gate, and pf-client-core's 163 unchanged.	2026-08-07 16:46:06 +02:00
enricobuehler	8c274d6256	fix(host/devtest): the probe asks stereo — its mono ask WAS the unopenable endpoint ... Measured resolution of the 0x88890008 mystery: IsFormatSupported said the capture accepts 2ch/48k shared while Initialize kept failing — because the probe itself had switched to a MONO ask for frequency counting, and this stack does not bridge channel counts on capture even under autoconvert. Every unopenable-endpoint verdict after that switch was the instrument, not the endpoint. Stereo ask restored; crossings counted on channel 0.	2026-08-07 16:44:01 +02:00

Interrogates the DRIVER, bypassing every endpoint-store stamping question: what the pins truly accept decides whether the mic leg has any coherent configuration, and whether an exclusive-mode mono open is an escape hatch.

enricobuehler	2eed9823e5	fix(host/audio): the mic pair gets the pad-proven coherent stereo stamp set ... The user challenged the format-locked-pins verdict, and the pad program is the counter-evidence: it hit the SAME 0x88890008 unopenable-endpoint signature and cured it with a COHERENT stamp set, after which the same driver family served 4ch happily. This branch previous attempts were contaminated twice over — a float device-format (the pad bisect proved the split must be PCM16 device / float mix+host) and no AudioEndpointBuilder restart (Restart-Service Audiosrv never touches its dependency, so endpoint configs were never rebuilt). Both mic endpoints now get one identical coherent stereo set; the octave-low hypothesis shifts from "raw crossing by design" to "the two endpoint stores disagreed (stereo render default vs mono capture default)".	2026-08-07 16:33:20 +02:00

enricobuehler	d2d5058d0b	fix(client/apple): the mic was never in the graph, so nothing ever pulled it ... ROOT CAUSE, from the reporter's device log: 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.	2026-08-07 16:30:29 +02:00
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.	2026-08-07 16:23:48 +02:00

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.	2026-08-07 16:10:22 +02:00
enricobuehler	7e34ca3d5e	fix(client/apple): a session that can't voice-process still sends its microphone ... 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.	2026-08-07 16:09:33 +02:00
enricobuehler	cc53b3d6b0	fix(host/audio): unwire the minted microphone — the driver mic path is unusable ... Final pitch-probe verdict on the SSM driver pair: the render pin is stereo-only, the capture pin mono-only (stamping either differently makes the endpoint unopenable), and the crossing between them is a RAW byte pass — so voice fed through the render endpoint reads back an octave low and no format stamp can fix it. S3 peak-based PASS = false pass; per the design doc revert clause the mic falls back to the name ladder (a virtual cable), pending the user re-decision. The SPEAKERS substrate keeps tier-0 (no driver crossing — a plain engine loopback tap, measured clean). minted_ids() publishes speakers only; the mic endpoints stay minted and recorded (provisioned()) for the micpitch probe and a possible future non-render transport, and their format stamps now pin each side to its pin one true format — healing the endpoints this branch earlier mis-stamped.	2026-08-07 16:06:56 +02:00
enricobuehler	5922cbe325	fix(host/audio): the minted mic pair declares stereo on BOTH sides ... Second measurement round: the driver render pin is STEREO-ONLY — the mono render stamp turned the endpoint unopenable (0x88890008 on every open, the incoherent-stamp signature the pad program documented). Since the crossing is raw, the coherent choice inverts: the CAPTURE side now declares the stereo float stream that actually crosses (fixing the octave-low voice), and the render has its stereo float default stamped explicitly — pinning the pair AND healing any endpoint a previous build left mono-stamped.	2026-08-07 16:01:39 +02:00
enricobuehler	ed98814145	fix(host/audio): the minted microphone renders MONO — voice was an octave low ... Measured with the new pitch probe: 440 Hz into the minted mic render came back as 220 Hz off its capture side. The driver forwards the render stream RAW into its mono capture, so a stereo-declared render (the driver-default we inherited) turns every stereo frame into two mono samples — half speed, octave down, exactly the field report. The mic render now gets a coherent MONO 48 kHz format set stamped alongside its name (PCM16 device format + float mix/host formats), making the engine downmix before the driver crossing. The mic pump keeps pushing stereo; shared-mode autoconvert handles the rest.	2026-08-07 15:57:19 +02:00

Peaks are pitch-blind — S3 passed while a potential half-rate link hid in the numbers (288k samples fits both the honest and the half-speed story). Every probe measurement now estimates the dominant frequency by zero crossings over the signal span, and `audio-probe micpitch` runs the decisive experiment against the LIVE minted pair: 440 Hz in, frequency out — ~440 = pair innocent, ~220 = the stereo render stream is forwarded raw into the mono capture.	2026-08-07 15:53:00 +02:00
enricobuehler	adf92939ec	fix(client/apple): the stats card's corner stops eating its own text ... 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.	2026-08-07 15:49:37 +02:00
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.	2026-08-07 15:47:33 +02:00
enricobuehler	b166c53cc2	fix(vkdecode): a refused device says what the refusal costs, and about which format ... 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".	2026-08-07 15:44:07 +02:00
enricobuehler	9582da07b4	fix(client/apple): the entrance goes underneath the scroll transition ... 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.	2026-08-07 15:38:38 +02:00
enricobuehler	48339326ae	fix(client/apple): the entrance keeps every card inside its own footprint ... 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.	2026-08-07 15:34:56 +02:00
enricobuehler	c06ee55b61	diag(vkdecode): --probe-decode reports what the driver says about video images ... 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.	2026-08-07 15:34:12 +02:00
enricobuehler	7993386900	feat(host/audio): the minted endpoints get their names — 'Punktfunk Speakers/Microphone' ... Field-measured necessity, not cosmetics: unstamped, the minted instances read 'Lautsprecher (2- Steam Streaming Microphone)' and even the box's owner picked the wrong device out of the Sound settings zoo (as did the S1 probe's name match before it). The provider now stamps device-desc + device-name through the pad program's proven machinery — write_stamps/ stamps_served, extracted from the pad-only stamp functions — with the same store-first/registry-fallback routes and settle/re-pass discipline. Names only: a wider stamp set makes AudioEndpointBuilder re-mint the endpoint under a new GUID (measured on pads). Stamping is best-effort (SYSTEM ACL route); the wiring never depends on names — identity stays the recorded id.	2026-08-07 15:33:52 +02:00
enricobuehler	eaa87ca0cc	fix(client/apple): the entrance stops dragging the scroll transition along with it ... 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.	2026-08-07 15:28:09 +02:00

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.	2026-08-07 15:23:10 +02:00
enricobuehler	769a8c049d	fix(client/apple): the entrance waits for the art, and every card swings ... 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.	2026-08-07 15:16:49 +02:00
