fix(pad-audio): close the twelve findings the sweep left open on this branch

Everything the 2026-08-03 haptics sweep filed against the pad-audio branch (P2 + P3).
Four of them are the difference between a feature that works and one that fails silently.

**B6 — nothing ever un-muted the coils.** Every rumble report asserts `HAPTICS_SELECT`,
which is SDL's "disable audio haptics" bit: the firmware mutes the very voice coils the
0xD1 stream drives. No code anywhere cleared it again, so ONE rumble left tier-A haptics
silent for the rest of that pad's life — no error, nothing in a log, and the host happily
streaming into a muted actuator. `DsDevice.ds5AudioHapticsReport` is the documented undo
(flag0 with both bits clear); written EP0-direct when the stream starts and again after a
rumble stop while a stream is live, because the stop report re-mutes on its way past.

**B10 — the desktop mix could reach a controller's coils.** Pad endpoints were filtered out
inside `plan()` only. The watchdog, Follow mode and the parked default all go through
`judge_default`, which classifies by NAME — and a pad endpoint is deliberately stamped
"DualSense Wireless Controller" so games treat it as the pad's speaker. No name rule could
ever catch one. It now refuses them by identity.

**B27 — an out-of-range pad aliased onto a real slot.** The 0xCD plane's pad is the only u16
index and every consumer narrowed it with `as u8` on an assumption nothing enforced, so wire
pad 256 steered pad 0's speaker volumes. Rejected at the decoder, which makes the narrowings
lossless by construction. An existing test had pinned the bug in place, asserting that wire
pad 513 round-trips; corrected, plus a test for the 256→0 alias specifically.

**B7 — caps that arrived late were never announced.** The renderer commits the tier-A trade
only once its sink opens, which is well past the arrival burst's two 100 ms ticks, and
`set_pad_audio_caps` only stored an atomic. The client believed it had pad audio while the
host emitted nothing. The input task now compares the live registry against what the last
arrival actually carried and re-arms the burst itself — no new plumbing, and no extra traffic
when nothing changed.

The rest: `needs_aeb_kick` is finally ACTED on (R4) — a stored-but-not-served endpoint is
declined rather than opened, because `AUTOCONVERTPCM` makes it succeed and mis-route; a failed
provisioning no longer latches `PROVISIONED` for the process lifetime (R5), and `host_cap`
retries, so a host that started while the audio stack was busy recovers at the next connect
instead of the next reboot; the loopback init timeout reaps its thread instead of detaching one
per ~2 s reopen (R6); kind-change restarts are bounded (R3) since the trigger is a client-sent
arrival; the devtest uses the endpoint's real channel mask (B11) instead of letting wasapi
derive 0x0F against the endpoint's 0x33; the render loop asks `is_session_ended()` rather than
spinning at nice -16 (R12); short writes are counted and reported instead of dropping the tail
in silence (R13); and a frame addressed to another pad is dropped before it can seed the gap
tracker from a foreign sequence space (R14).

Verified: punktfunk-host clippy -D warnings **0 on a real Windows box**; Linux/amd64 clippy 0
with **589 tests** (pf-client-core 114, pf-inject 101, punktfunk-client-android 20,
punktfunk-core 345+1+8); Android :kit: tests + :app: compile green; fmt clean.

Six punktfunk-host tests fail on that Windows box. FIVE fail identically on a tree with no
pad-audio code at all (QUIC `Rejected(SetupFailed)` — the box's network environment); the
sixth passes 3/3 in isolation and only failed under the parallel run, on a locally-bound
ephemeral port. Neither is this change.

Still owed: on-glass. This is a hardware feature and none of it has been on a real DualSense
since the merge.

+ * The pending interrupt-OUT reports for a captured controller: a bounded FIFO whose overflow
+ * policy knows which reports may be thrown away and which may not.
+ *
+ * The queue exists because only one thread may drive a connection's `UsbRequest`s, so writes from
+ * the feedback threads are handed to the reader thread rather than submitted directly. It has to
+ * be bounded — a stalled or unplugged device would otherwise grow it without limit — and the
+ * question is what to discard when it fills.
+ *
+ * The old policy was "newest wins": drop from the head until there is room. That is right for
+ * rumble, which is *level-styled* — the host re-sends it continuously, so a dropped frame is
+ * replaced milliseconds later and nothing is permanently lost. It is wrong for everything else.
+ * A lightbar colour, a player-LED mask and an adaptive-trigger effect are **one-shots**: the host
+ * sends them on change and never repeats them. Dropping one leaves the pad wrong until the next
+ * time that value happens to change, which may be never.
+ *
+ * So eviction is driven by an explicit [key] supplied by the caller, not by inspecting the bytes.
+ * That distinction cannot be recovered from the report itself: every DualSense output report

+German is primary throughout and uses the same informal "du" voice as the website
+(`punktfunk-website/messages/de.json`). English is a localisation, not a translation exercise — a
+few lines diverge where the German idiom does not carry.
+
+## Three things that contradicted the original brief
+
+1. **A Mac cannot be a host.** The brief suggested Mac copy could cover "running as a host/server
+   or client on Mac". There is no macOS host — `punktfunk-host` has no macOS capture, virtual
+   display, or encode backend. The macOS copy is client-only and says so explicitly.
+2. **The existing privacy policy is website-only.** It covers server logs, Plausible, and a
+   language cookie, and never mentions the apps. Linking it unchanged from App Store Connect is
+   the kind of thing that draws a reviewer's attention to analytics that have nothing to do with
+   the app. See `privacy-app-addendum.md` for the text to append.
+3. **App Review notes cap at 4000 characters**, not the unlimited field the brief implied. The
+   template is 3919 and fits.
+
+## Claims used, and where they come from
+
+Everything asserted in the copy was checked against the source rather than the marketing site:
+
+- Hardware decode, HDR/4:4:4, controller and input support — `clients/apple/README.md`
+- Entitlements and their justifications — `Config/Punktfunk.entitlements`,
+  `Config/Punktfunk-macOS.entitlements` (both carry detailed rationale comments)
+- Background audio mode and its 2.5.4 constraints — `Config/Info.plist`
+- "Collects no data" — verified by absence: no analytics SDK in `Package.swift`, no telemetry
+  symbols in `Sources/`, `URLSession` used only against the paired host
+- Host platforms and protocol details — root `README.md`, `docs/releases/v0.24.0.md`
+- Feature ship dates — `git tag --contains` on the relevant commits
+
+## Not done here
+
+`clients/apple` has no `PrivacyInfo.xcprivacy`. The app uses `UserDefaults`, which is a
+required-reason API, so a manifest is expected. Flagged at the end of `review-notes.md`; left
+alone because it is a code change, not copy.

+- Live Activities and the Hosts widget shipped long ago (`ba1caf02`, in v0.15.0+). They are safe to

+- The only Apple-visible feature unique to **v0.24.0** is the "Forward controllers" off switch
+  (`b297542c`), which is too niche to headline.

+Punktfunk streamt deinen Gaming-PC auf den Mac – in der exakten Auflösung und Bildwiederholrate deines Displays, über dein eigenes Netzwerk, ohne Konto und ohne Cloud.
+
+Punktfunk besteht aus zwei Hälften: einem Host auf dem PC, von dem du streamst, und dieser App auf dem Gerät, auf dem du spielst. Der Host ist quelloffen und kostenlos, läuft auf Linux und auf Windows 11 – auf dem Gaming-Rig unterm Schreibtisch, auf einem Laptop oder headless auf einem Server, an dem gar kein Monitor hängt.
+
+DEIN MAC BEKOMMT SEIN EIGENES DISPLAY
+
+Für jede Verbindung legt der Host ein echtes virtuelles Display an – in genau der Auflösung und Bildrate, die dein Mac meldet. Kein Skalieren, keine schwarzen Balken, kein Umsortieren deiner echten Monitore. Änderst du mitten im Stream die Fenstergröße oder gehst auf Vollbild, wird die Auflösung neu ausgehandelt, ohne die Verbindung zu trennen. Mehrere Geräte können gleichzeitig streamen, jedes auf seinem eigenen Display.
+
+SCHNELL, WEIL UNS DER GANZE WEG GEHÖRT
+
+Die nativen Apps sprechen punktfunk/1: eine QUIC-Steuerebene und eine verschlüsselte Datenebene mit Vorwärtsfehlerkorrektur, die Auflösung und Bildrate mitten im Stream wechselt, ohne neu zu verbinden. Dekodiert wird in Hardware über VideoToolbox – H.264, HEVC und AV1 auf Macs, die AV1 in Hardware können (M3 und neuer).
+
+FÜR DEN MAC GEMACHT
+
+• Im Fenster oder im Vollbild, auf jedem angeschlossenen Display
+• Maus und Tastatur gehen vollständig durch – Klick zum Fangen, Cmd+Esc oder Ctrl+Alt+Shift+Q zum Freigeben
+• Ein Stream-Menü in der Menüleiste: Maus freigeben, Trennen, Statistik einblenden
+• Mikrofon-Uplink mit Echounterdrückung – dein Mac wird zum Headset am PC
+• HDR mit PQ-Passthrough und ein optionaler Vollchroma-Modus (4:4:4), damit kleine Schrift und feine Linien scharf bleiben
+
+CONTROLLER, VOLLSTÄNDIG
+
+DualSense, Xbox- und weitere MFi-kompatible Controller. Beim DualSense gehen Rumble, Lightbar, Player-LEDs, adaptive Trigger, Touchpad und Gyro bis ins Spiel durch. Welchen Typ das virtuelle Gamepad am Host annimmt, richtet sich nach dem, was bei dir wirklich in der Hand liegt.
+
+DEINE BIBLIOTHEK, DEIN NETZWERK
+
+Installierte Steam-Titel und selbst hinzugefügte Spiele erscheinen als Raster mit Artwork und starten direkt. Hosts findet die App im Netzwerk von allein. Beim ersten Mal koppelst du einmalig mit einer PIN, danach verbindet sich der Mac über eine gepinnte Identität aus deinem Schlüsselbund – kein Konto, kein Login. Einen schlafenden PC weckt Punktfunk per Wake-on-LAN.
+
+MESSEN STATT GLAUBEN
+
+Ein gestuftes Overlay zeigt Bildrate, Bitrate und Latenz – über zwei Maschinen hinweg um den Uhrenversatz korrigiert, also eine Messung und kein Versprechen. Ein Geschwindigkeitstest pro Host schlägt eine passende Bitrate vor. Profile halten pro Host fest, wie gestreamt werden soll.
+
+WAS DU BRAUCHST
+
+Einen Punktfunk-Host auf einem Linux-PC oder auf Windows 11 (22H2 oder neuer) im selben Netzwerk. Der Host ist quelloffen (MIT/Apache-2.0) und kostenlos – Anleitungen und Quellcode findest du auf punktfunk.unom.io. Diese App ist der Client: ein Mac kann derzeit nicht selbst Host sein.
+
+Kein Konto. Keine Cloud. Keine Telemetrie. Die App erfasst keine Daten über dich.

+
+## Description (EN) — max 4000 characters
+
+```
+Punktfunk streams your gaming PC to your Mac — at your display's exact resolution and refresh rate, over your own network, with no account and no cloud.
+
+Punktfunk comes in two halves: a host on the PC you stream from, and this app on the device you play on. The host is open source and free, and runs on Linux and on Windows 11 — on the gaming rig under your desk, on a laptop, or headless on a server with no monitor attached at all.
+
+YOUR MAC GETS A DISPLAY OF ITS OWN
+
+For every connection, the host creates a real virtual display at exactly the resolution and refresh rate your Mac reports. No scaling, no black bars, no rearranging your actual monitors. Resize the window mid-stream or go full screen and the resolution is renegotiated without dropping the connection. Several devices can stream at once, each on its own display.
+
+FAST, BECAUSE WE OWN THE WHOLE PATH
+
+The native apps speak punktfunk/1: a QUIC control plane and an encrypted data plane with forward error correction, able to change resolution and frame rate mid-stream without reconnecting. Decoding is done in hardware through VideoToolbox — H.264, HEVC, and AV1 on Macs with an AV1 hardware decoder (M3 and later).
+
+BUILT FOR THE MAC
+
+• In a window or full screen, on any attached display
+• Mouse and keyboard pass straight through — click to capture, Cmd+Esc or Ctrl+Alt+Shift+Q to release
+• A Stream menu in the menu bar: release the mouse, disconnect, toggle the stats overlay
+• Microphone uplink with echo cancellation — your Mac becomes the headset on your PC
+• HDR with PQ passthrough, plus an optional full-chroma (4:4:4) mode that keeps small text and fine UI lines sharp
+
+CONTROLLERS, IN FULL
+
+DualSense, Xbox, and other MFi-compatible controllers. On a DualSense, rumble, lightbar, player LEDs, adaptive triggers, touchpad, and gyro all reach the game. The virtual gamepad the host presents takes its type from the controller actually in your hands.
+
+YOUR LIBRARY, YOUR NETWORK
+
+Installed Steam titles and games you add yourself appear as a grid with artwork, ready to launch. The app finds hosts on your network by itself. The first time, you pair once with a PIN; after that your Mac reconnects on a pinned identity stored in your keychain — no account, no login. Punktfunk can wake a sleeping PC over Wake-on-LAN.
+
+MEASURED, NOT PROMISED
+
+A tiered overlay shows frame rate, bitrate, and latency — corrected for clock skew across the two machines, so it is a measurement rather than a claim. A per-host speed test suggests a bitrate that matches your link. Profiles remember how each host should be streamed.
+
+WHAT YOU NEED
+
+A Punktfunk host on a Linux PC or on Windows 11 (22H2 or later) on the same network. The host is open source (MIT/Apache-2.0) and free — guides and source at punktfunk.unom.io. This app is the client: a Mac cannot currently act as a host.
+
+No account. No cloud. No telemetry. This app collects no data about you.

+## Keywords — max 100 characters
+
+Comma-separated, **no spaces after the commas** (spaces count against the limit). The app name and
+the subtitle are already indexed, so `punktfunk`, `schnell`, `lokal`, and `offen` are deliberately
+absent — repeating them would waste characters.

+```
+
+**Deliberately excluded:** `Moonlight`, `GameStream`, `NVIDIA`, `Steam`. Punktfunk genuinely is
+GameStream-compatible and does read your Steam library, but App Store Review Guideline 4.1 and the
+metadata rules disallow third-party app, product, and company names in the **keyword** field — it is
+a routine rejection. Saying it in the description is fine; the current descriptions avoid naming
+Moonlight and mention Steam only as a factual statement about your own library.
+
+The previous keyword set (`Game-Streaming, Lokal, Open-Source, Gaming`) spent characters on spaces,
+on `Lokal` (already in the subtitle), and on both `Game-Streaming` and `Gaming`, which share a stem.

+# Privacy — what to link from App Store Connect
+
+## The situation
+
+You already have a privacy policy at **punktfunk.unom.io/legal/privacy**. It is good, current
+(Stand: 28. Juni 2026), and localised DE/EN. But it is a **website** privacy policy: it covers
+server log files, Plausible Analytics on `analytics.unom.io`, the `PARAGLIDE_LOCALE` cookie, and
+self-hosted fonts. It does not mention the apps at all.
+
+That is a problem for App Store Connect in two directions:
+
+1. Apple requires the linked policy to describe **the app's** data practices. A reviewer following
+   the link finds a page about a website.
+2. It reads as *contradicting* a "Data Not Collected" declaration. The page prominently describes
+   analytics and a cookie. A reviewer who skims it sees "Reichweitenmessung mit Plausible
+   Analytics" and has every reason to question the App Privacy answers.
+
+**Recommendation:** keep the existing page and append an app-specific section to it (the text
+below), so one URL covers both. The alternative — a separate `/legal/privacy-apps` route — also
+works, but one URL is less to keep in sync.
+
+The page is CMS-driven (`src/routes/legal/privacy.tsx` renders Payload `RichText` blocks from the
+`pages` collection, slug `legal/privacy`, tenant `punktfunk`), so this is a CMS edit rather than a
+code change.
+
+## Confirming the "collects no data" framing
+
+Checked against the source rather than taken on trust, and it holds:
+
+- **No analytics, telemetry, or crash-reporting SDK.** `Package.swift` declares no such dependency.
+  A case-insensitive sweep of `Sources/` for `sentry|firebase|analytics|telemetry|amplitude|
+  mixpanel|crashlytics|posthog|plausible` returns 43 hits — 43 of them the word "amplitude" in
+  haptics code (rumble amplitude), and one the English word "plausible" in a comment.
+- **No outbound calls to us.** The only `URLSession` use is `LibraryClient`, fetching cover art
+  **from the paired host**, over a TLS session that pins the host's own certificate. The only
+  external URLs anywhere in the Swift sources are three UI links the user can tap: the docs site,
+  the source on `git.unom.io`, and the Discord invite.
+- **No account system.** Identity is a client keypair in the device keychain
+  (`keychain-access-groups`, `ClientIdentityStore`); pairing is SPAKE2 with a PIN, host-to-device.
+- **Data stays on device.** Saved hosts and settings live in a shared `UserDefaults` suite
+  (`group.io.unom.punktfunk`) so the widget can read them. Nothing syncs; there is no CloudKit
+  entitlement.
+- **No ATT.** No `NSUserTrackingUsageDescription` anywhere, consistent with no tracking.
+
+So **App Privacy → "Data Not Collected"** is accurate for all four platforms. Two caveats worth
+stating in the policy text anyway, because they are true and pre-empt questions:
+
+- The microphone uplink **is** audio leaving the device — but only to the host the user paired with,
+  encrypted, and never to us. Apple's questionnaire asks about data collected *by you or your
+  third-party partners*; streaming to the user's own machine is not collection. Saying so plainly
+  is better than staying silent about a microphone permission.
+- The apps are distributed through the App Store, so **Apple** collects its own analytics. That is
+  Apple's processing, not yours, but naming it avoids looking like an omission.

+# App Review notes
+
+## The core problem, stated plainly
+
+Punktfunk is the client half of a two-part system. Without a reachable host it shows a host list, a
+pairing sheet, and settings — and nothing else. There is **no demo or offline mode in a release
+build**: the mock-data screens in `Sources/PunktfunkClient/Screenshots/` are wrapped in `#if DEBUG`
+and are compiled out of anything you ship. A reviewer who launches the App Store build with no host
+on their network sees an empty "On this network" list.
+
+Guideline 2.1 requires you to supply whatever is needed to fully exercise the app. So you must
+attach **one** of:
+
+- **(a) A reachable demo host.** Best outcome — the reviewer sees the real thing. Requires a host
+  exposed to the internet with its UDP ports forwarded, plus a pairing PIN in the notes. The client
+  can add a host by IP or hostname, so mDNS discovery is not required for this path.
+- **(b) A demo video.** Apple accepts this for hardware- or setup-dependent apps. Less good: a
+  reviewer who cannot reproduce is a reviewer who can reject on something unrelated.
+
+**Attach (a) if you can keep a host up for the review window; (b) is the fallback.** Whichever you
+pick, fill in the placeholders before submitting — the template assumes (a) and marks the spots.
+
+> **⚠ Decide before submitting:** if you go with (b), replace the "CONNECTING TO OUR DEMO HOST"
+> section with the video URL and say explicitly that no host can be provided.
+
+---
+
+## Notes template — paste into App Store Connect
+
+The App Review Information "Notes" field caps at **4000 characters**. The block below is **3919**,
+and filling the five placeholders in shortens it further (the literal `[[FILL IN: …]]` text is
+longer than the values that replace it). If you add to it, re-check the count — an over-long note
+is silently truncated, and what gets cut is the end, where the privacy and entitlement answers
+live.
+
+```
+WHAT THIS APP IS
+
+Punktfunk is a low-latency game- and desktop-streaming client. It streams from a "host" the user
+installs on their own gaming PC (Linux, or Windows 11 22H2+), over their own network. The host is
+separate open-source software we publish at https://git.unom.io/unom/punktfunk; it is not sold,
+and this app has no purchases.
+
+This app is the client half only: it renders video and audio from the user's own machine and
+sends input back. There is no content library and no server of ours in a session.
+
+IMPORTANT: THIS APP NEEDS A HOST
+
+With no reachable host, the app can only show its host list, the pairing screen and settings --
+inherent to what it is, not an incomplete build. We have provided a live host for review.

+1. Launch Punktfunk. The main screen lists hosts on the local network. Ours is not on yours, so
+   add it by hand: "+" (top right) then "Add host"; on Apple TV, "Add host" on the main screen.
+2. Enter:  Host: [[FILL IN: hostname or IP]]   Port: [[FILL IN: port, default 47998]]
+   Name it anything, then confirm.
+3. The app connects and asks for a pairing PIN. Enter:  [[FILL IN: PIN]]
+   A one-time SPAKE2 pairing; afterwards the device is remembered and needs no PIN.
+4. The host's game library appears as a grid. Select any title to stream; video and audio start
+   within a few seconds.
+5. While streaming: stats overlay = Ctrl+Alt+Shift+S (or three-finger tap on iOS/iPadOS); release
+   mouse = Cmd+Esc or Ctrl+Alt+Shift+Q; disconnect = Ctrl+Alt+Shift+D.
+6. Settings (gear) covers decoder, bitrate, HDR, audio, controllers and profiles; the per-host
+   "Speed test" suggests a bitrate for the link.
+
+The host stays reachable throughout review. If you cannot reach it, please contact
+[[FILL IN: contact email]] and we will restore it promptly.
+
+WHY THE APP ASKS FOR WHAT IT ASKS FOR
+
+- Local Network: finds hosts via Bonjour (_punktfunk._udp) and connects to them -- the app's
+  entire purpose.
+- Microphone (optional, off by default): audio goes to the user's own paired host, appearing
+  there as a virtual microphone for voice chat. Never recorded, never sent to us.
+- networking.multicast: sends the Wake-on-LAN magic packet, which must go to a broadcast address:
+  a sleeping PC has no ARP entry, so unicast cannot reach it. Used for nothing else.
+- device.usb / device.bluetooth (macOS): the GameController framework reaches wired controllers
+  through IOHIDLibUserClient and wireless ones through startWirelessControllerDiscovery. USB also
+  drives DualSense rumble, which CoreHaptics will not. Without these, no controller input.
+- network.server (macOS): the app is outbound-only, but the App Sandbox gates bind() itself. Our
+  QUIC endpoint and UDP socket each bind a local port to receive host-to-client datagrams;
+  without this, no video, audio or rumble arrives.
+- UIBackgroundModes "audio" (iPhone/iPad): a session carries real, audible audio from the host,
+  and this keeps it alive if the user steps away briefly. Backgrounded, video decoding stops, only
+  the real audio keeps rendering, and a bounded timer disconnects automatically. We never play
+  silence to stay alive, nor use the mode outside an audible session.
+
+REGARDING BUILD 0.4.2 (3384)
+
+That build was rejected under 2.4.5(i) for a temporary-exception entitlement
+(mach-lookup.global-name, com.apple.audioanalyticsd), added on a mistaken belief about CoreHaptics
+rumble under the App Sandbox. We have since verified rumble works without it; this build carries
+no temporary exception.
+
+ACCOUNTS, PURCHASES, DATA
+
+No account, no sign-in, no in-app purchase. The app collects no personal data: no analytics,
+tracking, advertising or crash-reporting SDKs, and no connection to any server of ours during a
+session. Device identity is a keychain keypair used only to authenticate to the user's own host.
+
+Privacy policy: [[FILL IN: https://punktfunk.unom.io/legal/privacy]]
+```
+
+---
+
+## Before you submit — checklist
+
+- [ ] Fill every `[[FILL IN: …]]` placeholder. There are five.
+- [ ] Confirm the demo host is reachable **from outside your own network** — test it on cellular,
+      not on the LAN it lives on. This is the failure mode that wastes a review cycle.
+- [ ] Confirm the pairing PIN in the notes is the one the host will actually accept during the
+      review window, and that pairing is left open (it is on-demand in the web console).
+- [ ] Put at least one launchable title in the demo host's library. An empty grid after a
+      successful pairing looks like a broken app.
+- [ ] If submitting tvOS, verify the whole flow is reachable with the **Siri Remote alone**. A
+      reviewer will not have a controller paired, and "requires an accessory to navigate" is a
+      tvOS rejection.
+- [ ] Attach the demo video as a URL in the notes if you are going the (b) route.
+
+## Separately worth checking: the privacy manifest
+
+There is **no `PrivacyInfo.xcprivacy`** anywhere in `clients/apple`. The app does use
+`UserDefaults` (`HostStore` reads the `group.io.unom.punktfunk` suite), and `UserDefaults` is one of
+Apple's "required reason" APIs, which are expected to be declared in a privacy manifest. Apps
+missing a declaration typically get an automated **ITMS-91053** notice on upload.
+
+This is adjacent to the copy work rather than part of it, so nothing has been changed here — but it
+is worth adding a manifest declaring `NSPrivacyAccessedAPICategoryUserDefaults` with reason code
+`CA92.1` (access to an app group container) and `NSPrivacyTracking` set to `false`, before the next
+submission. Confirm the current reason codes against Apple's documentation rather than taking the
+code above on trust; the list has changed since it was introduced.

+# tvOS — App Store metadata
+
+Client only, living-room framing. Things the other platforms have that the **Apple TV does not**,
+and which the copy therefore avoids claiming:
+
+- **No microphone uplink.** There is no usable audio input on tvOS, so the "your Mac becomes the
+  headset" line does not transfer.
+- **No gamepad console shell.** `ShotScenes` builds the gamepad home/settings screens for iOS and
+  macOS only — tvOS uses the native focus engine instead.
+- **No AV1.** Apple TV 4K has no AV1 hardware decoder; HEVC and H.264 only.
+- Mouse/keyboard capture exists on tvOS but is not a living-room story, so it stays out.
+
+Kept, and genuinely tvOS-shaped: Siri Remote pointer navigation (`SiriRemotePointer`), controllers
+including the full DualSense feedback set, HDR passthrough, and Wake-on-LAN — which is the single
+best Apple TV feature, because it is what removes the trip to the other room.

+Punktfunk macht aus deinem Apple TV die Konsole für den Gaming-PC, der ohnehin schon im Haus steht – in 4K, mit HDR, über dein eigenes Netzwerk, ohne Konto und ohne Cloud.
+
+Punktfunk besteht aus zwei Hälften: einem Host auf dem PC, von dem du streamst, und dieser App auf dem Gerät, auf dem du spielst. Der Host ist quelloffen und kostenlos, läuft auf Linux und auf Windows 11 – auch headless auf einem Rechner, an dem gar kein Monitor hängt.
+
+VOM SOFA AUS, VON ANFANG BIS ENDE
+
+Anschalten, Host auswählen, spielen. Die App findet Hosts im Netzwerk von allein. Beim ersten Mal koppelst du einmalig mit einer PIN, danach verbindet sich der Apple TV über eine gepinnte Identität – kein Konto, kein Login, kein Abtippen von IP-Adressen. Steht dein Gaming-PC im Standby, weckt ihn Punktfunk per Wake-on-LAN und verbindet sich, sobald er wach ist. Niemand muss dafür aufstehen.
+
+DAS BILD, DAS DEIN FERNSEHER WIRKLICH KANN
+
+Für den Apple TV legt der Host ein echtes virtuelles Display an – in genau der Auflösung und Bildrate, die dein Fernseher meldet, bis 4K. Kein Skalieren, keine schwarzen Balken, und die Monitore am PC werden nicht umsortiert. Dekodiert wird in Hardware über VideoToolbox (HEVC und H.264), HDR wird als PQ durchgereicht, statt es flach zu rechnen.
+
+CONTROLLER, VOLLSTÄNDIG
+
+DualSense, Xbox- und weitere MFi-kompatible Controller. Beim DualSense gehen Rumble, Lightbar, Player-LEDs, adaptive Trigger, Touchpad und Gyro bis ins Spiel durch. Welchen Typ das virtuelle Gamepad am Host annimmt, richtet sich nach dem, was bei dir wirklich in der Hand liegt. Bedienen lässt sich alles mit der Siri Remote oder komplett mit dem Controller – die Oberfläche ist für die Fernbedienung gebaut, nicht für eine Maus.
+
+DEINE BIBLIOTHEK AUF DEM FERNSEHER
+
+Installierte Steam-Titel und selbst hinzugefügte Spiele erscheinen als Raster mit Artwork und starten direkt vom Sofa aus. Mehrere Geräte können gleichzeitig streamen, jedes auf seinem eigenen Display – der Apple TV im Wohnzimmer stört also niemanden, der am Schreibtisch weiterarbeitet.
+
+SCHNELL, WEIL UNS DER GANZE WEG GEHÖRT
+
+Die nativen Apps sprechen punktfunk/1: eine QUIC-Steuerebene und eine verschlüsselte Datenebene mit Vorwärtsfehlerkorrektur. Ein gestuftes Overlay zeigt Bildrate, Bitrate und Latenz – über zwei Maschinen hinweg um den Uhrenversatz korrigiert, also eine Messung und kein Versprechen. Ein Geschwindigkeitstest pro Host schlägt eine passende Bitrate für dein Netzwerk vor.
+
+WAS DU BRAUCHST
+
+Einen Punktfunk-Host auf einem Linux-PC oder auf Windows 11 (22H2 oder neuer) im selben Netzwerk. Für die beste Erfahrung hängt der Apple TV am Kabel oder an einem guten 5-GHz-WLAN. Der Host ist quelloffen (MIT/Apache-2.0) und kostenlos – Anleitungen und Quellcode findest du auf punktfunk.unom.io.
+
+Kein Konto. Keine Cloud. Keine Telemetrie. Die App erfasst keine Daten über dich.
+```
+

+
+## Description (EN) — max 4000 characters
+
+```
+Punktfunk turns your Apple TV into a console for the gaming PC you already own — in 4K, with HDR, over your own network, with no account and no cloud.
+
+Punktfunk comes in two halves: a host on the PC you stream from, and this app on the device you play on. The host is open source and free, and runs on Linux and on Windows 11 — including headless, on a machine with no monitor attached at all.
+
+FROM THE COUCH, START TO FINISH
+
+Turn on, pick a host, play. The app finds hosts on your network by itself. The first time, you pair once with a PIN; after that your Apple TV reconnects on a pinned identity — no account, no login, no typing IP addresses with a remote. If your gaming PC is asleep, Punktfunk wakes it over Wake-on-LAN and connects as soon as it is up. Nobody has to get up to make that happen.
+
+THE PICTURE YOUR TV CAN ACTUALLY SHOW
+
+For your Apple TV, the host creates a real virtual display at exactly the resolution and refresh rate your TV reports, up to 4K. No scaling, no black bars, and the monitors on your PC are left where they are. Decoding is done in hardware through VideoToolbox (HEVC and H.264), and HDR is passed through as PQ rather than flattened.
+
+CONTROLLERS, IN FULL
+
+DualSense, Xbox, and other MFi-compatible controllers. On a DualSense, rumble, lightbar, player LEDs, adaptive triggers, touchpad, and gyro all reach the game. The virtual gamepad the host presents takes its type from the controller actually in your hands. Everything is navigable with the Siri Remote or entirely with a controller — the interface is built for a remote, not for a mouse.
+
+YOUR LIBRARY ON THE BIG SCREEN
+
+Installed Steam titles and games you add yourself appear as a grid with artwork, ready to launch from the couch. Several devices can stream at once, each on its own display — so the Apple TV in the living room does not disturb anyone still working at the desk.
+
+FAST, BECAUSE WE OWN THE WHOLE PATH
+
+The native apps speak punktfunk/1: a QUIC control plane and an encrypted data plane with forward error correction. A tiered overlay shows frame rate, bitrate, and latency — corrected for clock skew across the two machines, so it is a measurement rather than a claim. A per-host speed test suggests a bitrate that matches your network.
+
+WHAT YOU NEED
+
+A Punktfunk host on a Linux PC or on Windows 11 (22H2 or later) on the same network. For the best experience, put your Apple TV on Ethernet or on good 5 GHz Wi-Fi. The host is open source (MIT/Apache-2.0) and free — guides and source at punktfunk.unom.io.
+
+No account. No cloud. No telemetry. This app collects no data about you.

 Stream to your **Steam Deck** without ever leaving Gaming Mode. This
 **[Decky Loader](https://decky.xyz/)** plugin adds a **Punktfunk** panel to the Quick Access Menu
-(the `…` button): discover hosts on your network, pair with a PIN, tweak stream settings, and launch
-a fullscreen, gamescope-focused stream — all from the couch, gamepad-navigable.
+(the `…` button): the hosts you can stream, the pinned cards you set up, and one tap into each.
 
-The video itself is the native GTK4 Linux client (the `io.unom.Punktfunk` flatpak); the plugin
-discovers, pairs, configures, and *launches it the right way* so gamescope fullscreens it — the same
-Steam-shortcut trick MoonDeck uses. Because it's built from real Steam UI primitives (`@decky/ui`),
-the panel looks and feels native to Gaming Mode.
+The plugin is a **launcher**, not a client. It doesn't decode video, browse your library, or hold
+any settings of its own — the Rust client does all of that, and the plugin's job is to start it
+*the right way* so gamescope fullscreens and focuses it (the same Steam-shortcut trick MoonDeck
+uses). Everything the panel doesn't do is one tap away in the client's own gamepad UI.
 
 ## What it does
 
-1. **Discover** — browses the LAN over mDNS for Punktfunk hosts, in both the QAM panel and a
-   fullscreen page; each host row opens a details view (address, pairing policy, certificate
-   fingerprint to cross-check against the host's log).
-2. **Pair** — for a host that requires it, a gamepad-navigable PIN keypad runs the SPAKE2 pairing
-   ceremony headlessly, then remembers the host so future streams connect silently.
-3. **Stream** — launches fullscreen via a branded "Punktfunk" Steam shortcut so gamescope focuses it.
-4. **Games** — each host row has a games button that opens its **library picker**: pin titles as
-   one-tap "Stream <Game>" rows in the QAM (jump straight into e.g. Playnite on the host), or
-   **"Open library on screen"** to launch the client's controller-driven, console-style library
-   browser (aurora backdrop + poster coverflow; A plays, B returns to Gaming Mode). Pins survive
-   plugin reinstalls (stored next to the client's config) and follow a host across IP changes
-   (matched by certificate fingerprint).
-5. **Settings** — the client's whole settings store, written to its config. Laid out like SteamOS's
-   own Settings: a left rail of categories (`SidebarNavigation`), one page each, so no page needs
-   scrolling. The categories and their order are the console settings screen's — Stream (resolution
-   / refresh / render scale / bitrate / compositor), Video (codec / decoder / GPU / HDR / 4:4:4),
-   Presentation (prioritize / smoothness buffer / V-Sync / VRR), Audio (channels / output + mic
-   device / echo cancellation), Controllers, Touch & mouse, Interface (stats overlay / auto-wake /
-   library / fullscreen). The device pickers are populated
-   from the session binary (`--list-adapters` / `--list-audio`); the GPU row appears only where
-   there is more than one adapter.
-6. **About** — plugin version, an explicit "Check for updates" button, the setup-guide link, and
-   a force-stop for a wedged stream client.
+1. **Hosts** — the hosts on your network plus the ones you've saved, in one list. Discovery is
+   mDNS; saved hosts are also probed directly, so a box reached over Tailscale or a VPN shows as
+   online even though it never advertises. Rows sort online-first, then most recently used.
+2. **Trust** — an unpaired host opens a small sheet with two ways in:
+   - **Request access** (the default) — no PIN. The host's operator approves this Deck in its
+     console or web UI and the stream starts by itself. See [Request access](#request-access).
+   - **Use a PIN instead** — the gamepad-navigable keypad, running the same SPAKE2 ceremony.
+3. **Stream** — launches fullscreen via a branded "Punktfunk" Steam shortcut so gamescope focuses
+   it. A sleeping host is woken first (the client runs the real wake-and-wait loop, then dials).
+4. **Pinned cards** — a *(host, profile)* pair renders nested under its host as `▸ <Profile name>`
+   and streams with that settings profile applied. Cards are the **shared** pinning model every
+   other client speaks, stored on the host's record — so one you make in the desktop client shows
+   up here, and vice versa. The plugin renders them; it doesn't create or edit them.
+5. **Open Punktfunk** — launches the client's **console home**: the host picker, add-host by
+   address, PIN pairing, the game library browser, and the **full settings screen**. This is where
+   everything the panel no longer does now lives.
+6. **About** — plugin version, "Check for updates", "Recreate library shortcut", and a force-stop
+   for a wedged stream.
 
 To leave a stream: the in-client controller chord (**L1 + R1 + Start + Select**), or close the
 "game" from the Steam overlay — either returns you to Gaming Mode.
 
+### Request access
+
+Request access is not a second pairing ceremony — it is a **launch**. The plugin saves the host
+with the fingerprint it **advertised**, then starts an ordinary identified connect with the
+handshake budget stretched to 185 s. The host *parks* that connection until its operator approves
+the device, then admits the same connection; the stream starts on its own, and the record flips
+to **paired** so every later stream is silent.
+
+**No advertised fingerprint, no request access.** That pinned fingerprint is the only thing
+standing between a 185-second wait and an impostor answering for the host, so a host you typed in
+by address gets the PIN path only — and the sheet says why. The plugin never trusts-on-first-use
+past a missing fingerprint.
+

 ## Architecture
 
+Everything below the panel is the CLI. `main.py` builds argv and maps exit codes; it parses none of
+the client's data files and re-implements none of its rules.
+
 | File | Role |
 | --- | --- |
-| `src/index.tsx` | Plugin entry: the QAM panel + route registration. |
-| `src/page.tsx` | The `/punktfunk` fullscreen page — Hosts (with per-host details) / Settings / About tabs. |
-| `src/settings.tsx` · `src/pair.tsx` | The settings screen (a `SidebarNavigation` of seven category pages over one shared settings object); the gamepad-navigable PIN-pairing modal. |
-| `src/library.tsx` | The per-host game picker (pin/unpin, "Open library on screen") + the pinned-game launch helper. |
-| `src/hostmgmt.tsx` | Add / edit host dialogs — mutate the shared known-hosts store (`client-known-hosts.json`) via the flatpak client's headless modes, so a host saved here shows up in the desktop client too. |
-| `src/ui.tsx` | Shared UI primitives for the fullscreen page + modals (right-aligned row actions, consistent Field layout). |
-| `src/hooks.ts` · `src/boundary.tsx` | Shared discovery/update/pins hooks + actions; the render error boundary. |
-| `src/steam.ts` | Steam-shortcut launch (`AddShortcut` / `SetAppLaunchOptions` / `RunGame`) — the focus-correct stream start. The shortcut's exe is `/bin/sh` with the wrapper passed as an argument, so the script never needs an exec bit (Decky's zip extraction drops it and the root-owned plugins dir can't be chmodded by the unprivileged backend). Launch extras ride env-prefix tokens: `PF_LAUNCH=<id>` (pinned game) / `PF_BROWSE=1` + `PF_MGMT=<port>` (on-screen library); ids are validated space/quote-free at pin AND launch time. |
-| `src/backend.ts` | Typed `callable` bridges to `main.py`. |
-| `bin/punktfunkrun.sh` | The launch wrapper the Steam shortcut runs (so the window is focusable); maps `PF_LAUNCH`/`PF_BROWSE`/`PF_MGMT` to `--launch`/`--browse`/`--mgmt`. An older flatpak ignores the flags harmlessly (plain stream / hosts page). |
-| `main.py` | Backend: `discover` (via `avahi-browse`) / `pair` / `library` (headless flatpak `--library`, TSV) / pins store (`decky-pinned.json`) / settings / `kill_stream` / `check_update` (with an explicit CA-bundle search — Decky's embedded Python has no usable default TLS roots on SteamOS). |
-| `scripts/test-backend.py` | Stdlib-only checks for the backend's pure parsers (TSV, error classes, avahi TXT) + the pins round trip. |
+| `src/index.tsx` | Plugin entry + the QAM panel: update banner, hosts (with nested pinned cards), the console-home door, about. |
+| `src/hooks.ts` | `useHosts` (one call merging discovery and the saved store), the update hooks, and the launch action. Also the trust-state model the rows render. |
+| `src/trust.tsx` · `src/pair.tsx` | The trust sheet (Request access / Use a PIN instead / Cancel) and the gamepad-navigable PIN keypad. |
+| `src/steam.ts` | Steam-shortcut launch (`AddShortcut` / `SetAppLaunchOptions` / `RunGame`) — the focus-correct stream start. The shortcut's exe is `/bin/sh` with the wrapper passed as an argument, so the script never needs an exec bit (Decky's zip extraction drops it and the root-owned plugins dir can't be chmodded by the unprivileged backend). |
+| `src/backend.ts` · `src/boundary.tsx` · `src/os-icon.tsx` | Typed `callable` bridges to `main.py`; the render error boundary; the host row's OS mark. |
+| `bin/punktfunkrun.sh` | The launch wrapper the Steam shortcut runs (so the window is focusable). Reads `PF_REF` / `PF_PROFILE` / `PF_REQUEST_ACCESS` / `PF_BROWSE` and runs `punktfunk launch` — or the session's `--browse` for console home. |
+| `main.py` | Backend: four thin CLI shells (`discover` / `hosts` / `pair` / `trust_host`) plus the Steam-side work only a plugin can do — `runner_info`, `shortcut_art`, `apply_controller_config`, `kill_stream`, `check_update` / `update_client` (with an explicit CA-bundle search — Decky's embedded Python has no usable default TLS roots on SteamOS). |
+| `scripts/test-backend.py` | Stdlib-only checks: argv shape, the CLI exit-code mapping, and the Steam configset editor. |
 | `plugin.json` · `update.json` | Decky manifest; CI-baked update channel. |
 
+### Why the launch goes through Steam
+
+gamescope only gives focus and fullscreen to the window tree Steam launched via `reaper` (it
+detects the "current app" by AppID — gamescope#484). A client spawned from the plugin's own
+backend comes up invisible and unfocused. So the plugin registers non-Steam shortcuts whose exe is
+`/bin/sh` running `bin/punktfunkrun.sh`, and starts them with `RunGame`.
+
+There are **two** shortcuts, both named `Punktfunk` so Steam keys them to one Steam Input
+configset (the key is the lowercase name): a hidden, stateful one that carries the stream, and the
+visible, stateless library entry that opens console home.
+
 ## Limitations / next steps
 
-- No manual "add host by IP" entry yet (discovery is mDNS-only).
-- No in-stream overlay inside the plugin — the client owns the session once launched.
-- Pairing needs the operator to **arm pairing on the host** so it shows the PIN; the plugin can't arm
-  it remotely.
+- **Profiles and pinned cards can't be created here** — the panel renders them; making one needs
+  the desktop client, or the client's own gamepad UI once that work lands. A Deck with no profiles
+  simply sees host rows, and nothing is broken.
+- **Per-game pins are on hold.** The shared model pins *host+profile*; nothing in the shared store
+  persists a pinned *game* yet. The old `decky-pinned.json` is left on disk untouched so a later
+  migration can read it.
+- Pairing with a PIN needs the operator to **arm pairing on the host** so it shows the PIN; the
+  plugin can't arm it remotely. Request access needs no arming — just an approval.
+- **A parked connect looks like a hanging one.** The plugin toasts before launching a request-access
+  stream to set expectations, which is a patch rather than a fix; teaching the session's connect
+  screen the same "waiting for approval" copy the console shell already has would pay off for every
+  shell.

-             fires scrollIntoView. Because the panel is offset by a *transform* (not by scroll
-             position), scrollIntoView can't satisfy it by scrolling any one ancestor, so it walks

-// SHAPE OF THIS SCREEN. Thirty rows is too many to scroll past on a thumbstick, so they are split

-// the whole point of the split: the rail is the index, so nothing is more than one hop away.
-//
-// The categories, their order, and the wording of the rows are the console's settings screen
-// (pf-console-ui/src/screens/settings.rs) — that screen is the other settings editor a user
-// reaches without leaving Gaming Mode, and two different orders for one store is how people stop
-// trusting either. It shows them as one steppable list because it has no pointer and no room for
-// a rail; here they become the rail's pages, same groups, same sequence. Three more rules:
-//
-//   • A setting that depends on another is INDENTED under it and DISABLED, never hidden — the
-//     console dims those rows rather than dropping them, and a row that vanishes as you toggle
-//     the one above it is a moving target for a thumbstick.
-//   • A picker whose options this device doesn't have doesn't appear at all (the GPU row on a
-//     one-GPU Deck). A dead control is worse than an absent one.
-//   • Anything that behaves differently *here* than it does on a desktop says so in its own
-//     description, rather than being silently dropped from the screen.
-//
-// The accepted gamepad/compositor/codec/decoder names mirror punktfunk-core's `*Pref::from_name`
