enricobuehler	327301e012	docs(release): the 0.24.0 notes cover the two controller fixes ... PRs #25 and #26 are going into this release, and neither was in the notes. Both are user-visible and easy to have lived with without knowing why: force-feedback stopping for good after a controller reconnect (roughly half of reconnects, every platform), and an unplugged pad staying visible to the game for the rest of the session (every time, if it was your only controller). The whatsnew line for the rumble fix is Play listing copy and that file has a 500-character ceiling, so "A decoder hiccup no longer snowballs into a burst of broken frames" loses "snowballs into" for "causes" — same meaning, and the new line is kept short. 498 of 500 used.	2026-08-03 19:52:05 +02:00

enricobuehlerandClaude Opus 5	62573d2781	docs(release): the 0.24.0 notes cover the ABR sweep ... PR #28 merged after the bump commit was written, so the notes described a release that no longer matched the tree. Merged origin/main and added what it brings: 45 commits since v0.23.0 now, not 39. Four user-facing entries, because eleven defects in one path is not one bullet and the pinning is the headline the field reports have been describing for months ("my bitrate is stuck at 20"): - the 20 Mbps pin itself, with the measured escape (150 Mbps in ~16 s against ~17 minutes) — the number is the point, since the old behaviour was not "slow to climb" but "never arrives" - the five single-window lessons the controller treated as permanent - throughput counted with FEC parity, which rose with the loss it was meant to detect - the silent host re-target, which made a client's first climb a request to go DOWN The Under the hood section gets the whole sweep in one bullet rather than scattering it, and PUNKTFUNK_ABR_MAX_MBPS moves from the probe bullet into it (it now binds at construction, not only on probe-learned ceilings, so it no longer belongs to the probe). Play notes gain an ABR line and now run 459/500 chars; the gate's real logic was re-run against the file, including the byte-identical check. Voice check over everything above "Under the hood" is clean of internal vocabulary. Re-verified after the merge: cargo metadata --locked resolves, cargo fmt --all --check clean, doc lazy-continuation scanner 0 hits. #28 touched no manifest, so the version bump and the versions-only lock diff are untouched.

enricobuehlerandClaude Opus 5	93608980ae	chore(release): bump workspace version to 0.24.0 ... A minor bump: 39 commits since v0.23.0 across 121 files. Mostly a fix-up of 0.23.0 — the slice wire's reassembler sized every sentinel-opened AU at max_frame_bytes and lost 9 of 12 in-flight frames on any link that reorders, which is the freeze field reports were seeing on Android and the session client — plus the desktop presenter rebuild (intent model, V-Sync/VRR as real settings, the driver's queue-free vblank mode where it exists), the Decky settings tab growing from nine rows to the whole store, a "Forward controllers" off switch for passthrough couches, and plugin output finally reaching the console's log page. The canary base is already 0.24 — scripts/ci/pf-version.sh derives it as one minor ahead of the latest stable tag — so this is the version canary has been publishing against all along. No wire, ABI or driver-protocol change: wire protocol 2, C ABI 14, virtual-display driver protocol 6 and the Windows virtual-gamepad channel 3 are all identical to 0.23.0. No new capability bits either — VIDEO_CAP_MULTI_SLICE took the video-caps byte's last free bit in 0.23.0 and nothing here needed the next one. The only generated-header change since the tag is documentation (probe elapsed_ms semantics), already committed and verified by ci.yml's staleness gate on main. Lock touched for the 32 workspace members only, via `cargo update --workspace`: diff against origin/main is versions-only, 32 insertions and 32 deletions (the 33rd 0.23.0 line in the lock is the third-party `wasapi` crate, which sits at 0.23.0 itself — same trap as the last cut). `cargo metadata --locked` resolves; `cargo fmt --all --check` clean in both the main and the packaging/windows/drivers workspaces. api/openapi.json is deliberately left at 0.23.0: it tracks API edits and lags a release, as in every prior cut. Notes at docs/releases/v0.24.0.md, per docs/releases/README.md — authored with the bump so CI's ensure_release seeds the release body at tag creation. Play's "What's new" at docs/releases/whatsnew/v0.24.0.txt (409/500 chars), which android.yml now gates as a hard failure at step 1; the gate's own logic was run locally against this file, including the byte-identical-to-another-release check.

enricobuehler	1feeff3ca6	Merge pull request 'fix(abr): eleven defects from a sweep of the Automatic-bitrate path' (#28) from fix/abr-sweep into main ... Reviewed-on: #28	2026-08-03 17:33:28 +00:00
enricobuehler	1ae8b4d4ca	fix(client/abr): let the ceiling follow a host-initiated re-target ... Interaction between two fixes in this series. The host now tells the client when a rebuild re-resolves an Automatic rate, and that rate can legitimately sit ABOVE the client's climb ceiling — the ceiling is the negotiated start rate until the capacity probe raises it, while the host's re-resolve answers "what do these pixels actually need" (a 1080p session mirroring a 4K panel resolves ~3× higher). Left alone, the client would learn the new rate, notice it was above a stale ceiling, and step the host straight back down off the rate it had just chosen for itself. So an ack raises the ceiling to meet it. `set_ceiling` only ever raises and still clamps to PUNKTFUNK_ABR_MAX_MBPS, which is the one limit that should bind here. No effect on ordinary acks: a climb is never requested above the effective ceiling to begin with.	2026-08-03 18:53:02 +02:00
enricobuehler	33ecd8e1a5	fix(client/abr): a granted climb disproves the learned cap ... Completing the cap-escape fix. Backing the re-probe clock off to 12 s got the client asking again quickly, but each ask only LIFTED the cap by +12.5 % — so even a host that had fully recovered still granted the session its real ceiling one small step at a time, ~4 minutes from the 20 Mbps default to a 300 Mbps link. The crawl was never the point; re-learning was. A request granted IN FULL at or above the cap is the host's own word that the limit is gone. Drop the cap outright at that point instead of nudging it. A standing limit is unaffected — it answers the same re-probe with another short ack, which re-latches it and doubles its clock, exactly as before. Adds the end-to-end regression the sweep was really about: a session pinned at 20 Mbps by a transient cadence refusal, under a probe-measured 300 Mbps ceiling, now reaches 150 Mbps in 22 windows (~16 s) where it used to need ~17 minutes.	2026-08-03 18:53:02 +02:00
enricobuehler	48565c4e9e	fix(host/abr): stop pinning Automatic sessions, and tell the client when the rate moves ... Two host-side halves of the same sweep. **The cadence latch.** `cadence_degraded` — which makes the control task refuse bitrate CLIMBS — was latched true for as long as the session was escalated (adaptive capture depth or pipelined retrieve), independently of whether encode was still missing deadlines. The client cannot tell that refusal apart from an encoder's real ceiling: both arrive as a short `BitrateChanged`, and two identical ones latch a cap. Escalation needs ~20 net behind-frames, which a startup hitch supplies while the ABR is still in slow start at the 20 Mbps default — so one transient pinned the whole session there, long after the escalation had bought back the headroom it was for, and escaping cost +12.5 % per 60 s. An escalated session is still judged strictly (ANY net behind-frame keeps it flagged, where an unescalated one gets the full bucket), but being escalated no longer flags it by itself: escalating exists so cadence CAN be held, and once it is, refusing climbs refuses the thing that worked. The rule moves into `encode_behind_cadence` so it is stateable and testable. **The silent re-target.** `adopt_built_bitrate` publishes the rate a rebuilt pipeline actually opened at — `build_pipeline` re-resolves an Automatic rate whenever the source delivers a size the session did not negotiate, the mirrored-panel case — and the encoder's own clamp can land below what the control task already acked. Neither reached the client, whose controller keeps its own copy of that number as its climb base. A 1080p client mirroring a 4K panel therefore believed 20 Mbps while the host encoded 60, and its first climb computed from the stale base asked for 40: a re-target DOWNWARD, paying an encoder rebuild to get there. Both paths now push the applied rate to the control task, which sends `BitrateChanged` — the existing 9-byte message, which already means precisely this and which clients already handle arriving unprompted. No wire-format change, no capability negotiation, old clients unaffected. 2 host tests added.	2026-08-03 18:53:02 +02:00
enricobuehler	e9a7373c76	fix(client/abr): measure delivered throughput in media bytes, not wire bytes ... The controller's two throughput-driven gates both compare "what the pipeline carried" against the ENCODER's target: the utilization gate asks whether a clean window actually tested that target (a calm menu proves nothing), and the never-decaying proven mark bounds how far every later climb may step. Both were fed `bytes_received`, which counts every accepted datagram — headers, FEC parity, probe filler, audio. So the figure rose with the redundancy the host adds in ANSWER to loss: at 25 % FEC the gate passed with the encoder emitting ~55 % of target, and the proven mark inherited the same inflation permanently. The signal was weakest exactly on the lossy links it exists for. Count data-shard payload separately at the reassembler's routing decision — the same place, and for the same reason, the probe counters are already stamped — and feed the ABR that. First time both gates are dimensionally honest: a media rate compared against a media target.	2026-08-03 18:53:02 +02:00
enricobuehler	f7a8c2013d	fix(client/abr): the controller stops learning the wrong lessons from one window ... Six defects found by a sweep of the Automatic-bitrate path, all of them the same shape: a single window, or a single refusal, taught the controller something it then treated as permanent. - Rolling baselines (OWD, client decode, host encode) armed off ONE sample. The baseline is a rolling minimum, so one window IS the floor — and `on_ack` deliberately clears the encode baseline after every decrease we ourselves asked for, re-opening that hole each time. A calm re-seed window followed by ordinary motion read as 4 ms of "congestion", backed off, cleared again, and ratcheted toward the floor on a link that was never the problem. All three now need BASELINE_MIN_WINDOWS of evidence before they may fire, via one shared `score_baseline` (the three copies had already drifted apart). - A mode switch rebased only the encode baseline. Decode and OWD are just as mode-scoped: 4K120 decodes slower and puts bigger frames on the wire than 1080p60, so the old floor was one the new mode cleared on its first window — ~30 s of every window scoring bad, i.e. a backoff every other window. A switch UP in mode cratered the rate instead of raising it. `proven_kbps` goes with them; throughput the old mode's decoder digested is not evidence about this one. - `proven_kbps` — never decayed, and permanent authority over how far every later climb may step — was raised by any window without a decode rise, including ones scored SEVERE. The windows that overstate delivered throughput are exactly the damaged ones: a stall's backlog draining at once, a flush's queue, the FEC surge answering a loss burst. Now only clean windows raise it. - A learned cap escaped at +12.5 % per ~60 s. The host cannot distinguish a durable encoder ceiling from a climb refused while it is transiently behind cadence, and the latter routinely latches during slow start at the 20 Mbps default — from which crossing the gap to a probe-measured ceiling took upwards of twenty minutes. Re-probe after 12 s instead, doubling the interval each time the lift is immediately re-learned: a transient is out in one interval, a real ceiling settles into a slow poll. - The decode cap latched AT the rate that choked, authorizing a climb straight back into the failure, and a bare jump-to-live flush could teach a "decoder knee" from what was a network event. It now latches just under the choke rate (inside the ±1/8 band the evidence already required) and only credits a flush where the decode signal is absent and cannot speak for itself. - PUNKTFUNK_ABR_MAX_MBPS bound only probe-learned ceilings, not the negotiated start rate — so the one knob an Automatic session gives the operator did nothing when the session already started above it. It now binds at construction, and a session sitting above its ceiling steps down to it (no congestion signal will ever find that: the link is fine, the cap is policy). Also: a SetBitrate dropped by a full control queue counted toward MAX_UNACKED, so three of them retired the controller for the session while logging that an "older host" was at fault. The pump now tells the controller what happened. Wire format and ABI untouched. 34 abr tests green (3 new).	2026-08-03 18:53:02 +02:00

enricobuehler	9979489b56	fix(host/pads): an unplugged controller actually disappears ... Unplug a controller mid-session and the virtual pad it was driving outlives it: the game keeps seeing a connected, permanently idle device for the rest of the session. The single-controller session — the common case — hits this every time. `PadSlots::sweep` needs two passes to retire a pad. The first pass to see the mask bit clear only ARMS the 300 ms devnode-churn grace; the drop lands on a later pass. But sweep runs only from a state frame, and the producer emits exactly one frame per detach — `native/input.rs` guards the emit on the bit still being set — so for a pad with no still-changing sibling in the same manager, the second pass never comes. Nothing periodic reaches sweep: `heartbeat` and `pump` walk the slots without it. Split the two halves. `sweep` still folds a frame's mask into the grace clocks, and `reap` — new — drops whatever has run out, with no frame needed. Every manager now reaps on the periodic pump it already runs, so the teardown completes ~300 ms after the detach instead of never. `reap` deliberately cannot arm a clock: it only reads `inactive_since` and clears it, so a pad whose bit never went clear has nothing to run out and no amount of reaping can drop it. That is what makes it safe on a hot loop, and it keeps the anti-flap guarantee intact — a mask that blips clear and returns still never churns a devnode. The two existing tests hand-fed a SECOND removal frame, which production never sends; they passed while the real path leaked. Both now drive the unplug through a pump tick, and PadSlots gains three tests pinning the new invariants. Verified non-vacuous: with the reap neutered, both manager tests fail with "the pump tick never completed the unplug". Behaviour notes: this puts UI_DEV_DESTROY on the GameStream control thread's budget for the first time, and a mask glitch longer than the grace now really does flap — which is SWEEP_GRACE working as documented, so the constant stays. Found by the 2026-08-03 force-feedback sweep (B2 — see the backlog in punktfunk-planning design/haptics-sweep-2026-08-03.md).	2026-08-03 17:34:47 +02:00
enricobuehler	14502769e0	fix(host/input): rumble comes back when a controller does ... Unplug a pad mid-session and plug it back in, and roughly half the time it never rumbles again for the rest of the session. The removal arm restarted the pad's rumble sequence counter. The client's reorder gate does not restart: `rumble_last_seq` lives for the whole QUIC connection and has no reset path, so it still holds whatever the pad reached before the unplug. Restarting the host counter therefore hands the client a seq it has already seen, and its wrapping half-space compare drops every envelope until the counter climbs back past the stored value — up to 128 sends. Since the counter only advances on a level change or a ~120 ms renewal while a level is non-zero, that spans many separate rumble events, so it reads as a flaky controller rather than a clean outage. Whether it bites is decided by how much the pad rumbled beforehand, which is why it looks intermittent: a pad that never rumbled before the re-plug has `None` on the client side and always heals. The counter now survives, matching the sibling pad-state gate — whose comment eleven lines above already explains that a re-plug must arrive with a still- newer seq to be accepted. The three clears that actually end the stale lease move into `clear_pad_feedback`, whose signature deliberately has no seq parameter so the arm cannot regress by editing. Covered by a regression test that drives the real wire encoder and the real client gate, and asserts the pre-fix behaviour is genuinely rejected across the whole forward window, so it cannot pass vacuously. Found by the 2026-08-03 force-feedback sweep (B1/T5 — see the backlog in punktfunk-planning design/haptics-sweep-2026-08-03.md).	2026-08-03 16:57:11 +02:00
enricobuehlerandClaude Opus 5	db1faef9fb	docs(plugins): don't name a release that doesn't exist yet ... The /tmp troubleshooting note said PrivateTmp=yes shipped "until 0.23.1". 0.23.0 is the latest tag and the next number isn't decided, so that could be wrong on arrival.

enricobuehlerandClaude Opus 5	442ea12b96	test(mgmt): pin the two things that would silently break plugin logging ... The runner holds the PLUGIN token and nothing else — on Windows its LocalService principal cannot read the admin one at all. `plugin_may_access` is an exclusion list, so `/plugins/logs` is reachable today only because it happens not to match `/ui-credential`. If that ever changed, plugin logs would go quiet in the console with no other symptom and no failing test. Now asserted on that lane directly. The second test covers ingest end to end through `GET /logs`: the `plugin:` target prefix the console's Host/Plugins filter keys on, the level coercion (an unranked level would sort as 0 and hide under every filter setting), a sourceless line being attributed to the runner rather than to nothing, the caller's timestamp surviving the trip, and an oversized batch being refused whole.

enricobuehlerandClaude Opus 5	1e56705b86	fix(sdk/log-ship): a busy plugin's lines survive a POST, and the shutdown tail is actually sent ... Two bugs in the log shipper, both found by re-reading it rather than by a failing test, and both of the kind where the symptom is a missing log line — which is the one failure a logging path must not have. The recursion guard was held across the whole `await fetch`, and `enqueue` checked it. So every line logged while a POST was open was dropped, silently. That window is milliseconds when the host is healthy and much longer when it is not, and the lines lost are whatever a busy plugin happened to be saying — so the shipper was least reliable exactly when it was most needed. The flag now guards flush re-entry only (the interval can fire while a slow POST is still open, and two concurrent flushes would splice disjoint batches out of one queue and deliver them out of order). Nothing on the shipping path logs, so the recursion it was guarding cannot form; that is now a stated rule at the top of the file rather than a flag that costs real lines. An explicit `flush()` hit that same re-entry guard and returned having sent nothing. That is the shutdown path: the runner flushes once more after its units' finalizers have run, and those last lines are the ones that say whether the shutdown was clean. It now waits for an in-flight flush before starting its own. Both are covered by tests that fail against the previous code. The first needed a server that signals when it has the request — logging merely "after calling flush()" passes against the bug, because flush yields at its own awaits long before the fetch starts.

enricobuehlerandClaude Opus 5	365caa23be	fix(plugins): plugin output reaches the console's log page, and /tmp is no longer hidden from the runner ... A user could not get the VirtualHere plugin to use their VirtualHere client and asked, reasonably, where the logs were. There was no good answer, and the reason they were stuck turned out to be ours. **The runner could not see /tmp.** `punktfunk-scripting.service` set PrivateTmp=yes, which hands the unit a private tmpfs. But integrating with things already running on the box is the entire job of a plugin, and on Linux those talk over /tmp: VirtualHere's client IPC is the FIFO pair /tmp/vhclient + /tmp/vhclient_response, X11 is /tmp/.X11-unix. So the plugin launched the vendor binary happily and could then never reach the daemon behind it — while the same command worked perfectly in the operator's own shell, because that shell has the real /tmp. No config change could fix it, which is exactly the loop the report described. PrivateTmp is now off, with /tmp added to ReadWritePaths (which ProtectSystem=strict would otherwise make read-only). **Plugin logs now land in the console.** Plugins are not host child processes — the runner is a separate bun process that import()s each plugin in-process — so nothing they print passed through the host's tracing, and the console's Logs page could not show a single plugin line. The fallback was journalctl on Linux; on Windows the runner's scheduled task writes no log file at all, so a failing plugin was diagnosable only by stopping the task and re-running the runner by hand. Both mean shell access on the host box, which is what the console exists to avoid — and it left the one question a stuck user asks with no answer. So the runner now tees its output to POST /api/v1/plugins/logs, and those lines join the host's own ring under one cursor, targeted plugin:<name>. The console grows a Host/Plugins switch beside the level filter; an empty Plugins view says the thing that is actually usually wrong (the runner isn't running) rather than "adjust the filter". The shipper keeps stdout authoritative — journald and foreground output are unchanged whatever the host is doing — and is built so that logging can never hurt the thing being logged: it never throws into a caller, holds a bounded queue that drops oldest and then says how many, backs off when the host is away (a restart is normal), and re-sends a batch the host failed to take. Lines logged while a POST is in flight are kept, which cost one round to get right: the first version held its recursion guard across the await and silently dropped exactly the lines a busy plugin produces. Runner lines that report a failure (a refused unit file, a crashed plugin, a give-up) now go out at warn/error instead of all arriving as INFO, so the console's level filter means something for them.

enricobuehlerandClaude Opus 5	f71bee917b	Merge origin/main; the presenter rebuild's four settings join the sidebar ... `#20` landed while this branch was open and added four settings the console screen groups under a new "Presentation" header: Prioritize, Smoothness buffer, V-Sync and Follow variable refresh. A branch whose whole claim is "everything the store holds is reachable" cannot merge past those, so they get a Presentation page of their own, in the console screen's position (after Video, before Audio) and with its wording. Smoothness buffer is indented under Prioritize and disabled until the intent is Smoothness — the same relationship the console's `enabled` gate draws. The docs conflict resolves to main's side plus this branch's correction: the 4:4:4 advertisement claim main rewrote is the current one and stays, while "Android, Decky and the console home don't offer it" was wrong about two of the three before this branch and about all three after it. The four new settings' paragraphs pick up the console home and Decky the same way. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 00:40:05 +02:00
enricobuehlerandClaude Opus 5	6de78213ee	feat(decky): the settings tab covers the whole store, as a SteamOS-style sidebar ... The stats overlay was the visible half of a general problem: nine of the client's settings had a row here and twenty didn't, so a Deck that never sees a desktop could not reach its own decoder, chroma, HDR, audio layout, echo cancellation, touch or mouse model, scroll direction, auto-wake, or either audio endpoint. Everything the store holds is here now — except the two things a plugin backend genuinely cannot answer, named in `backend.ts` so the next reader doesn't go looking: which physical pad is player 1 (SDL's live device list lives in the client process, and no CLI enumerates it) and the session's remembered window size, which is not a preference. Thirty rows is too many to scroll past on a thumbstick, so they are split across a `SidebarNavigation` — the left-rail-of-categories layout SteamOS's own Settings uses, and the one Deck users already know. Every page fits on screen without scrolling, which is the point: 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 settings screen's — it is the other settings editor reachable 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. The six pages take one shared settings object rather than each holding state, so a change on one is visible on the others the moment you switch. Three more rules: - A dependent setting is INDENTED under what it depends on and DISABLED, never hidden: mic device and echo cancellation under the microphone, controller type under forwarding. The console dims those rows for the same reason, and a row that vanishes as you toggle the one above it is a moving target for a thumbstick. The device row at the foot of Audio is rendered even while it reads, for that reason. - A picker with nothing to pick doesn't appear: the GPU row shows up only where the enumeration found more than one adapter, so it is absent on a Deck and present on a Bazzite desktop with a dGPU. - A setting that behaves differently HERE says so in its own description rather than being dropped. Capture system shortcuts holds nothing back under gamescope; fullscreen-on-stream can't lose to a launch that always passes `--fullscreen`; the client's library toggle isn't this plugin's browser. Each says which. The device pickers are real, not stubs: `list_devices` reads `--list-adapters` and `--list-audio` off the SESSION binary, the same two enumerations the GTK shell shells out for because it links no Vulkan itself. It is cached for the life of the backend (that call inits Vulkan and PipeWire) with an explicit Refresh for the headset you just plugged in, and a failure — a client too old to ship the session binary — leaves the pickers on Automatic and says so instead of claiming you have no devices. `_parse_audio_endpoints` is split out and unit-tested with the malformed lines that must never reach a picker. Two smaller honesty fixes fall out of building it. A Dropdown can only display a value that is one of its options, and this store has four other writers — so a stored value the table doesn't list is carried as its own entry rather than rendering blank or, worse, showing a different value than the stream will use. And a stored audio endpoint that isn't currently connected keeps a "(not connected)" entry, the way the Linux picker keeps "(not detected)", instead of silently re-pointing the next stream at the default. The Settings tab's wrapper deliberately stops being a scroll area: a SidebarNavigation given an indefinite height to fill collapses its rail, so the pane hands it the full height and keeps its hands off the overflow, and the footer inset moves inside the pages. The docs claimed nine things about this plugin that are no longer true, and three about the console home that stopped being true when its own row set grew on 2026-07-31 (4:4:4, echo cancellation, auto-wake and the library toggle are all there in `screens/settings.rs`). Both corrected. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 00:21:15 +02:00
enricobuehler	aa3bcfd0d0	Merge pull request 'feat(client/present): desktop presenter rebuild — intent engine, V-Sync/VRR, display-stat split, settings UI' (#20) from worktree-desktop-presenter into main ... Reviewed-on: #20	2026-08-02 22:06:37 +00:00
enricobuehlerandClaude Opus 5	6b3c582eb1	feat(client/present): use the driver's queue-free vblank mode where it exists ... `VK_PRESENT_MODE_FIFO_LATEST_READY_EXT` is FIFO's tear-free vblank pacing that presents the LATEST READY image at each refresh and retires the older ones, instead of draining a queue. That is precisely what the software glass gate emulates — so where the driver offers it, the driver does the job, and it does it exactly where the gate matters most: a surface with no MAILBOX gets newest-wins behaviour back without the app holding frames. Found by asking the surface what it actually offers rather than trusting a comment: the previous commit's `surface present modes` line read back `[MAILBOX, 1000361000, FIFO]` on NVIDIA/Wayland, and 1000361000 is this mode. The extension postdates the Vulkan headers ash 0.38 is generated from (1.3.281), so there is no binding — hence the bare number in the log. It is hand-declared here: mode value, extension name, and `VkPhysicalDevicePresentModeFifoLatestReadyFeaturesEXT` spliced into the device pNext chain. One trap worth naming: the SURFACE advertises the mode even with the extension disabled, and using it on that basis is undefined — so the ladder only offers it when the device feature actually came back true and we enabled it. The gate/probe predicate had to split in two, and the distinction is the point: * `needs_glass_gate()` — FIFO and FIFO_RELAXED only. NOT this mode: gating on top of a driver that already retires stale images would hold frames back to emulate something the presentation engine is doing, paying the serialisation twice, which is the ~27 ms the last commit measured. * `vblank_locked()` — the whole FIFO family INCLUDING this mode, because it still presents on the refresh boundary, so the VRR cadence probe's premise ("with VRR off, a present waits for vblank") still holds. Ranking: MAILBOX first (measured good at 1.4 ms), then LATEST_READY, then plain FIFO — so a MAILBOX-less surface reaches newest-wins in the driver rather than in our gate. MEASURED ON GLASS (.21, NVIDIA 610.43.03, GNOME/Wayland): the extension probe, feature enable and swapchain creation all succeed with a mode ash has no binding for. Default ladder selects MAILBOX with `fifo_latest_ready=true`; the VRR ladder selects `present_mode=1000361000` and measures `display 2.6 ms (pace 0.6 + latch 2.0)` — against 13-28 ms for plain FIFO + gate on the same box. The vblank-locked path is now MAILBOX-class. That changes the previous commit's reversal. The VRR ladder was reverted to opt-in because it led with plain FIFO and cost ~27 ms; led with LATEST_READY it costs 0.6 ms over MAILBOX. So `allow_vrr` is automatic again WHERE THE DEVICE OFFERS THE MODE, and stays behind `PUNKTFUNK_VRR_FIFO=1` where it does not — on those drivers the ladder would fall back to plain FIFO and the regression returns. Both branches are pinned by tests. This also retires a dead switch: the "Follow variable refresh rate" row did nothing at all after the reversal, and now does something real on any driver with the extension. ⚠ Still unverified off this box: whether Windows and Intel drivers expose the mode at all. Nothing measured here carries over — Windows Vulkan WSI goes through DXGI, so exposing the enum and mapping it usefully onto flip-model semantics are separate questions, and Intel is a different vendor stack again. Both facts are logged unconditionally now (`surface present modes` + `fifo_latest_ready=`), so one run on any box settles it. The code is safe either way: the mode is only requested where the device feature enabled, and `allow_vrr` only goes automatic there — everywhere else the shipped MAILBOX-first behaviour is unchanged.

enricobuehlerandClaude Opus 5	e08474d96d	fix(client/present): log the surface's actual present modes, and document the VRR opt-in ... "AMD's Windows driver offers no MAILBOX" is the premise the FIFO glass gate is built on, and it has been carried in a code comment rather than measured. Present modes are a property of the (surface, device) pair — they vary by platform surface, driver version and fullscreen state — so the only way to settle it is to read them back from real machines. One unconditional log line makes every field log answer the question. First reading, .21 (NVIDIA 610.43.03, GNOME/Wayland): surface present modes available=[MAILBOX, 1000361000, FIFO] Two things fall out. No IMMEDIATE and no FIFO_RELAXED on this surface, which is why a PUNKTFUNK_PRESENT_MODE=immediate run reported mode=fifo — the pin was not offered and the ladder fell through; previously that looked like a puzzling result and is now evidence. And 1000361000 is VK_PRESENT_MODE_FIFO_LATEST_READY_EXT: FIFO's tear-free vblank pacing that presents the LATEST READY image instead of draining a queue — the driver-native version of what the glass gate emulates in software, and a candidate to replace it wherever the driver exposes it (needs VK_EXT_present_mode_fifo_latest_ready enabled at device creation, so a work package rather than a tweak). Also documents PUNKTFUNK_VRR_FIFO, which the previous commit introduced without a docs entry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 00:01:56 +02:00
enricobuehlerandClaude Opus 5	f422ae3e38	fix(client/present): what the first on-glass session found, including a reversed default ... WP6 ran against .21 (CachyOS, RTX 5070 Ti, NVIDIA 610.43.03, GNOME/Wayland, 1080p60 HDMI, VRR provably disabled — `org.gnome.mutter experimental-features` is empty), host and client on the same box, `VK_KHR_present_wait` available. Five defects that unit tests and both CI gates had passed over: 1. The latch learner and the VRR probe observed NOTHING. Both derived spacings with `windows(2)` inside a single batch, but the run loop drains present-wait samples every pass, so a batch is normally ONE stamp. `period_us` read back exactly the mode fallback — correct by luck on a 60 Hz panel, wrong the moment a mode lies, which is the entire reason PanelGrid exists. The tests fed 40-stamp batches, a shape the live loop never produces. Spacings are now measured against the previous stamp across calls. 2. The VRR reference was circular. It compared spacings against the LEARNED period, but the grid cannot be learned from our own presents when the stream runs below panel rate — we only ever observe multiples ≥ our frame interval, so the learner adopts our own cadence and every delta is on-grid by construction. It learned 18-22 ms from a 40-50 fps stream and reported VRR on a display with VRR off. The reference is now the DISPLAY MODE's period, which is the vblank grid presents actually quantize to. 3. The probe is meaningless outside FIFO. MAILBOX deliberately decouples presents from scanout, so its stamps are never grid-quantized: same panel, same minute, FIFO read `no` (correct, period 16.4 ms) and MAILBOX read `yes` (wrong). Outside a FIFO-family mode the honest answer is Unknown, and that is now what it reports. 4. Round evaluation was per-CALL rather than per-sample, so the verdict depended on how the caller batched its stamps. Closed inside the sample loop now, with a test pinning bulk-vs-one-at-a-time equivalence — the same invariant (1) violated, in a second place. 5. `force_latency` was dead code without the `pyrowave` feature: a warning in the `--no-default-features` build CI actually ships (the Windows ARM64 leg). The gate only ever tested default features; it now tests both. DESIGN REVERSAL — the VRR FIFO-first ladder is opt-in (`PUNKTFUNK_VRR_FIFO=1`), no longer default. It shipped default-on for `allow_vrr` + fullscreen, which is the default configuration. Measured A/B, same box, back to back, reproduced across three runs: FIFO+engine `display 28.4 ms (pace 11.8 + latch 16.6)` versus MAILBOX `1.4 ms (0.2 + 1.2)`. Under a compositor the FIFO present's on-glass confirmation arrives a whole refresh later and the presenter serialises behind it. The VRR upside is real in principle but UNMEASURED — no VRR panel was available — and a default that is measurably ~27 ms worse on the hardware we could test, bought against an unproven win on hardware we could not, is the wrong way round. A test pins the default to MAILBOX; flip it back when a VRR panel confirms the win. NOT measured, and not claimed: the FIFO glass gate's own headline. The standing queue only forms when the stream rate approaches the panel rate, and an idle GNOME desktop is damage-driven at 40-50 fps on a 60 Hz panel, so `gated`/`forced` read 0 in every mode and the mechanism never engaged. The 11-13 ms figure is still the code's inherited documentation, not a fresh measurement. It needs its actual target: AMD-on-Windows (no MAILBOX, direct scanout) under load. Rig caveats recorded rather than smoothed over: host and client shared one GPU, so absolute latencies are contended and run-to-run variance was large, and it could not be visually confirmed what the physical screen showed. Mode selection, the fallback ladder, the VRR verdict and the counter plumbing are robust to that; absolute numbers are not. Gates: fmt, clippy -D warnings over the five client crates AND the `--no-default-features` build (added because defect 5 hid there), 160 tests.

enricobuehlerandClaude Opus 5	e38e3c44c9	feat(client/present): V-Sync and VRR become real settings, and VRR is measured ... WP3 of design/desktop-presentation-rebuild.md. The `vsync` and `allow_vrr` settings have existed since WP1 but nothing consumed them — the swapchain picked MAILBOX-or-FIFO once, from an env var, and froze. This makes them mean something, which is also what unblocks their settings rows (deliberately withheld from WP5 rather than shipped as dead switches). Present-mode selection is now a preference ladder, not a constant: * V-Sync off — IMMEDIATE, then FIFO_RELAXED, then the tear-free modes. Asking to tear and silently getting vsync is a lie, so the mode that actually took is named in the stats line and a refused preference is logged requested-vs-active. * V-Sync on + VRR allowed + fullscreen — FIFO first. On a variable-refresh panel with direct scanout the FIFO present IS the flip, so the panel follows the stream's cadence instead of a fixed grid; MAILBOX would decouple presents from scanout and re-quantize to the compositor's clock. This is only safe because WP2's glass gate bounds the standing queue that historically made FIFO costly. * Otherwise — MAILBOX then FIFO, the shipped default, unchanged. `PUNKTFUNK_PRESENT_MODE` still pins a mode outright and now falls back to the settings (rather than to mailbox) when the name is unknown. VRR detection is MEASURED, never queried. No portable query exists — SDL exposes none, Wayland does not report adaptive-sync state, Windows surfaces nothing through Vulkan — and the platforms that do answer have been caught lying (see the Android per-uid refresh-rate finding). The discriminator is quantization: on a fixed-refresh panel every on-glass instant lands on the vblank grid, so the spacing between presents is ~k×period for whole k even when the stream runs slower than the panel (it just picks a larger k); under real VRR the panel refreshes when we present, so the spacing follows our own cadence and sits off the grid. `CadenceProbe` folds each delta to its distance from the nearest multiple of the learned period and takes the median. Tri-state: it stays Unknown below 24 deltas and after a display change, so `vrr` is reported only when it has been measured — never inferred from what the display claims. Also fixes the read-once refresh rate: `native.refresh_hz` was sampled at startup and never revisited, so dragging the window to another monitor left a 60 Hz-seeded clock pacing a 144 Hz panel. `WindowEvent::DisplayChanged` now relearns the latch grid, resets the cadence verdict, and clears the served-slot latch. Settings rows for both, on all three surfaces (GTK, WinUI, console). The console's V-Sync row is reachable in Gaming Mode, which is the only editor a Deck user has. Gates: punktfunk-rust-ci linux/amd64 — fmt, clippy -D warnings over pf-client-core, pf-presenter, pf-console-ui, the session binary and the GTK client, 160 tests (the two new ones cover every ladder and both cadence regimes, including the case that matters most: a stream slower than a FIXED panel must still read as fixed). WinUI leg on the Windows runner .133: clippy=0 tests=0, against a tree proven by content to contain the edit. ⚠ On-glass validation is still owed and is NOT claimed here: every box with a real display was powered off when this landed, so the VRR ladder and the detector have been exercised only against synthetic stamps in unit tests. Rebase follow-up: `20de58a7` landed the same "panel grid can be wrong in both directions" defect fix on Android and extracted the corrected learner into `punktfunk_core::phase::PanelGrid` for the iOS and desktop presenters to share. This clock had the identical bug — it capped the learned period at the display mode's refresh, and the mode is only a CLAIM, so a display really running slower than it advertises pinned a grid whose instants never arrive, for the session, with no way back. Adopted the shared learner rather than carrying a second, buggier copy; still fed the window's MIN spacing, which preserves the k×period resistance the cap was actually aimed at while the streak requirement lets a genuinely slower panel be discovered. New test: seed 120 Hz, real panel 60 Hz, the clock must climb back out. Took the same commit's third lesson too: the adaptive margin widened on a latch over 1.5×period (a number picked here), and now widens on the latch exceeding one period plus the lead already applied — the slot actually aimed at.

enricobuehlerandClaude Opus 5	b1ac4d02de	feat(client/present): the display stat splits, and the intent reaches the settings UI ... WP4 + WP5 of design/desktop-presentation-rebuild.md, on top of the WP1/WP2 engine. The engine shipped with no way to choose it and no way to see what it cost; this closes both. WP4 — the display stage splits into `pace` (decoded → present-submit, our own pipeline) + `latch` (submit → on-glass, the presentation queue and the vblank wait), off the `submitted_ns` stamp WP2 already carried. That split is what makes a high `display` self-diagnosing: latch dominating is the vsync floor or a standing queue, pace dominating is us. A `present:` line joins the Detailed tier naming the live swapchain mode — the answer to most "why is my latch a whole refresh" questions, since a MAILBOX request silently lands on FIFO wherever the driver has no mailbox — plus the engine's counters, rendered only when they are non-zero so a healthy latency session shows just the mode. Deviation from the plan: the planned `display_adj` twin is NOT here. It was specified as `display − latch_p50` for parity with the Apple HUD's shaved figure, but with a real per-sample `pace` percentile that twin is the same quantity derived worse (subtracting percentiles). `pace` IS the Apple-comparable number — Apple subtracts its OS present floor, the latch is ours — and the user docs now say exactly that. WP5 — Prioritize + Smoothness buffer on all three surfaces: the GTK dialog (a new Presentation group on the Display page), the WinUI settings page, and the console settings screen, which is the ONLY editor reachable in Gaming Mode and so the one that decides whether Deck users can reach this at all. The buffer control follows the intent the way echo cancellation follows the mic: hidden on the desktop shells, dimmed and inert on the console, where a row that vanished mid-list would shift everything under the cursor. The V-Sync and VRR rows are deliberately NOT here. Their settings exist and are profile-routed, but the swapchain does not honour them until WP3, and a toggle that does nothing is exactly how "Full chroma (4:4:4)" shipped inert on desktop for three releases after being announced. Buffer labels carry no millisecond hints (Apple/Android derive them from the session refresh): under a Native mode the shells do not know the refresh at settings time, so the captions state the cost as one refresh per frame rather than a confident wrong number. Docs: the stats page documents the split and the `present:` line, and stops claiming Linux/Windows measure to the present instant (untrue since present_wait); client-settings documents both new rows and drops the stale claim that the desktop 4:4:4 toggle has no effect (it was wired to VIDEO_CAP_444); configuration documents PUNKTFUNK_PRESENTER and PUNKTFUNK_PRESENT_DEBUG. Gates: punktfunk-rust-ci linux/amd64 — fmt, clippy -D warnings over pf-client-core, pf-presenter, pf-console-ui, the session binary and the GTK client, 158 tests. The WinUI leg cannot be reached by any Linux or macOS check, so it was compiled on the Windows runner .133: clippy -D warnings and tests both exit 0, against a tree proven by content to contain the edit. ⚠ The first run there reported a false pass — the script printed its done-marker while the log carried a test failure (a STATUS_DLL_NOT_FOUND launch failure, ffmpeg's DLLs missing from PATH); the harness now echoes each phase's exit code so the verdict is a fact in the log rather than an inference from a marker.

enricobuehlerandClaude Opus 5	5f55fa874a	feat(client/present): the desktop presenter gains the Apple/Android intent model ... WP1+WP2 of design/desktop-presentation-rebuild.md. The shared Linux/Windows session client presented arrival-paced with no pacing layer at all: two depth-2 newest-wins hops into a drain-to-newest and an immediate present. That IS the lowest-latency intent, but it was unnamed, unselectable, and had no alternative — and on a surface without MAILBOX (AMD's Windows driver offers none, and any compositor holding images does the same) the swapchain's own FIFO becomes a standing queue worth a measured 11-13 ms at 60 Hz. WP1 — the settings cluster, under the keys the Apple client already writes into the shared profile catalog (present_priority / smooth_buffer / vsync / allow_vrr): mismatched names would ride SettingsOverlay::extra, carried but never applied. PresentPriority::resolve mirrors the Android reference exactly (anything but an explicit "smooth" is latency; a buffer outside 1..=3 becomes 2), so a profile authored on any client means the same thing on all of them. Only the first two are consumed here; vsync/allow_vrr land in WP3. WP2 — the engine (present_pace.rs, pure state + arithmetic, 6 tests): - FrameStore: newest-wins slot, or the smoothing FIFO with preroll-to-capacity, drop-oldest overflow, and an underflow that re-arms the preroll (repeat by omission) — the Apple/Android semantics, with qDrop/qDry counters. - LatchClock: the panel grid learned from VK_KHR_present_wait glass stamps, min positive spacing capped by the mode refresh (measured, never queried — VRR and Android's per-uid refresh lie both punish trusting a reported rate). It now also publishes the host-facing LatchGrid, so the phase-lock report and the local scheduler cannot disagree about the grid. - PresentGate: one undisplayed present in flight on FIFO surfaces, with the 100 ms stale force-open. This is the standing-queue killer, and it is inert on MAILBOX/IMMEDIATE and without present timing — where behaviour stays byte-for-byte the shipped arrival pacing. Wiring: glass samples drain every pass (a 1 Hz batch would starve clock and gate) and the waiter pushes an SDL wake, so a gate reopen never waits out the event timeout; smoothness serves one frame per latch slot and tightens the loop's wait to that deadline; the adaptive slot margin starts at 0 and widens +500 us per missed window toward 2.5 ms (a fixed lead was measured to be pure display tax). PUNKTFUNK_PRESENTER=arrival disables the whole engine for field A/B without a rebuild. PyroWave collapses smoothness to latency for the stream: its plane-ring retirement accounting assumes the depth-2 newest-wins hand-off, and all-intra frames make buffering moot anyway. Gates (punktfunk-rust-ci, linux/amd64, sources touched first so a warm target cannot print a vacuous Finished): clippy -D warnings across pf-client-core, pf-presenter and punktfunk-client-session; 80 + 32 tests pass; rustfmt clean.

enricobuehlerandClaude Opus 5	8af6e2dd02	feat(decky): the stats overlay gets an off switch in Gaming Mode ... Field report: "as of version 0.23 of this plugin, there is no setting to toggle off the stat overlay." Correct, and it never had one — no commit in `clients/decky` has ever touched a stats key. Every other client does: the GTK dialog, the Windows page, the Apple app, and the console's own settings screen all carry the four-tier picker. The tier defaults to on. `Settings::default` is `show_stats: true` and `stats_verbosity: None`, which `Settings::stats_verbosity` resolves to Normal — so a Deck that has only ever been configured through this panel streams with the overlay up and no way here to put it down. What escapes exist are not discoverable: Ctrl+Alt+Shift+S wants a keyboard, and the three-finger touchscreen tap is documented in `docs/stats`, not on the glass. The console's picker is reachable (X on console home), but that is a different shortcut than the one-tap stream this panel launches, and a user editing stream settings here has no reason to look there. So the row lands here, last in the section, matching the console's wording. It writes `stats_verbosity` AND the legacy `show_stats` in the same pairing `Settings::set_stats_verbosity` keeps, so a client too old for the tiers still honours an Off chosen here; it reads them back the way `Settings::stats_verbosity` does, so a pre-tier file — including every file this plugin wrote before today — shows the Normal the stream actually runs at. `set_settings` stops replacing the file and merges onto it instead. This JSON is shared with the desktop client and the console, and holds many more keys than this panel models (decoder, GPU, profiles, touch/mouse model). The panel reads it once when it mounts, so a wholesale write posts a snapshot that predates anything another editor stored while it sat open — silently reverting it. That was invisible until 0.23.0: `9c5af8d7` fixed the GTK shell handing the session a spec built from `Settings::default()`, and only since then does this file reach a stream at all.

enricobuehlerandClaude Fable 5	d839f4c2b6	fix(client/windows): settings stop going stale behind your back, and the log has a door ... A field reporter's codec setting "changed by itself" between sessions. Nothing writes the negotiated codec back — what they saw was a stale snapshot. `AppCtx.settings` is loaded ONCE at process start and the page renders from it, but this process is not the file's only writer (the spawned session persists its match-window size, the console UI and Decky save too), so the page showed values another process had already replaced — until a row was touched and `commit`'s rebase pulled the file in, at which point the value visibly jumped. The 2026-07-31 rebase fix covered the whole-file writers and missed two spots: nothing re-based on page ENTRY, and the profile-scope commit arm cloned the snapshot without reloading, so overlay absorption diffed against stale globals. Both now re-base on the file. Two more ways a setting could vanish or cost time: * An older binary's whole-file save DROPPED a newer client's keys — `Settings` had no unknown-key passthrough, unlike `SettingsOverlay`, whose `extra` map already gives profiles exactly that contract. Extended to the globals: additive, empty on every existing store, and an empty map serializes to nothing so no file churns. (`save()` was already temp+rename, so the torn-file → silent-Default reset was closed.) * "Check the client log" never said WHERE. Settings ▸ About grows an Open log folder row (%LOCALAPPDATA%\punktfunk\logs, folder not file so the rotated .old generation is in reach), and the failed-spawn banner now names the path. The 4:4:4 caption said "HEVC only, and only where the host can encode it", which sends people hunting: the host gate is PyroWave or an NVENC backend. It says so now.

enricobuehlerandClaude Opus 5	b297542c4d	feat(clients/input): controllers can stop being forwarded, for couches that hand the pad over another way ... A controller that reaches the host by USB passthrough — VirtualHere and friends, or simply a pad plugged into the host — arrived there twice: once as the real device, once as the virtual pad this client built from the same hands. Games read both, so a stick drifts against the centred second pad and menus take every input twice. New per-client setting, "Forward controllers", default on (today's behaviour). It is tier-P, so a profile can decline what another profile forwards. On Linux and Windows it is deliberately stronger than "send nothing". Opening a controller is what CLAIMS it — SDL's HIDAPI drivers take the device node — and a claimed device is one a passthrough tool cannot bind, so with this off the session opens no slot at all and never enables the Valve HIDAPI drivers. Menu navigation is untouched: the launcher still opens the active pad, and a session supersedes menu mode whether it forwards or not, so the pad is free for the whole time a stream is up. The consequence, documented at both the setting and the chord: the controller escape chord is read off forwarded pads, so it is unavailable there. The Apple and Android input stacks claim nothing, so those clients keep their slots and their chords and only gate the wire sends — losing tvOS's only controller way out of a stream would have been the worse bug. Android does stop its DualSense and Steam Controller 2 USB captures, which do claim the device. Surfaces: GTK, WinUI, the console settings screen, Apple's touch and gamepad settings, the Android touch and gamepad settings, and Decky (which also hides the rows that now have nothing to act on). Everywhere the "which pad" and "pad type" rows grey out while it is off. Verified: cargo clippy --all-targets -D warnings + 79 tests on pf-client-core, pf-console-ui, punktfunk-client-session and punktfunk-client-linux (linux/amd64 container, gate proven non-vacuous with a planted error); swift build for the Apple clients; gradle compile + 49 unit tests for Android (likewise proven); tsc for Decky. clients/windows is UNCOMPILED — both Windows boxes were offline; its edits were reviewed against the helper signatures by hand.

enricobuehlerandClaude Fable 5	98e040fd01	fix(host/stream): the wire holds the session rate when the display outruns it ... PUNKTFUNK_VDISPLAY_HZ_MULT promises extra display refreshes without one extra frame on the wire, but the frame-driven trigger enforced its pace only as a per-gap floor: sleep to 0.9×interval, then wake on arrival. A source that always has a frame pending — the overdriven display under uncapped content — settled at 0.9-interval spacing, 1.11× the negotiated rate. That is the field report's 132 fps on a 120 fps session: ten percent more bitrate, encode and decode for frames a 120 Hz panel can only drop. A credit bucket (PaceBudget) now pins the long-run average at the pacing rate: credit accrues at one frame per interval of real elapsed time, capped at 1.25 frames of post-stall burst, and every submitted frame spends one. A grab may run early only against banked credit, so the 0.9 floor keeps its per-gap jitter headroom while the average cannot exceed the rate — and a source at or below it banks faster than it spends and is never delayed. Anchoring to real elapsed time also keeps the synchronous-encode overlap the arrival-anchored floor bought (the owed fraction absorbs a constant encode tail instead of stacking on top of it), and it cannot fight the phase lock's submit grid: both agree the period is the interval.

enricobuehlerandClaude Fable 5	5174a59832	fix(capture/kwin): a hidden cursor leaves the stream — KWin's id-0 meta is the hide ... Since the 0.22.0 cursor work (the seat-pointer park + the metadata composite), a KWin capture-model stream always has a cursor — and it never went away again: not in game, not in Big Picture, not with a controller in hand (field report, 2026-08-01). The host blended the arrow forever because pf-capture deliberately ignores SPA_META_Cursor id 0, and once `visible` latched true nothing on Linux ever cleared it. Two producer contracts meet on id 0, and one flag now carries which one a stream follows. KWin rewrites the cursor meta on EVERY enqueued buffer and writes id 0 whenever Cursor::isOnOutput says the pointer is not in this stream — which covers both a globally hidden cursor and a client null-cursor surface (empty geometry intersects nothing). There id 0 IS the hide, and honoring it is what lets a game hide the pointer mid-stream. Mutter only rewrites a buffer's meta when the cursor changed, so recycled buffers carry stale id-0 regions between damage frames — honoring those flickered the cursor off between hovers (on-glass round 5), and that path keeps its last-known-state behavior. The flag rides from the backend that created the output (correct for registry-pooled reuse too — a kept display only ever matches its own backend) through capture_virtual_output into the parser's CursorState. The portal-monitor path stays on the stale-meta contract: the only thing routed through it today is Mutter's HDR mirror. Verified on .25: pf-capture 45/45, punktfunk-host 369/369, clippy -D warnings clean (pf-capture, punktfunk-host, cursor-probe), fmt clean. On-glass KDE validation still owed.

enricobuehlerandClaude Opus 5	c2a6d30d7b	fix(android/decode): a codec input slot the feeder can't fill goes back, and so does the AU ... `AMediaCodec_getInputBuffer` returning null for an index the input-available callback had just handed us dropped both the slot and the access unit on the floor. Every sibling path in this loop recycles the slot — the orphan-part discard and the oversize drop both say so in as many words — because nothing was written and nothing was queued, so it is still ours. Forgetting it leaks one of the codec's input buffers per occurrence: we never use it again and the codec never frees what it never received, so the pipeline runs out of input slots, `pending_aus` overflows into its drop-oldest arm, and the resulting keyframe storm reads as a decode fault rather than a bookkeeping one. The AU went with it, silently — no keyframe request, no freeze gate, unlike every other loss path here — leaving a hole in the reference chain whose concealment was free to reach the screen. Both go back now. `break` rather than `continue`, because a codec that cannot hand out an input buffer it has just advertised is in no state to be fed the rest of the parked queue on this pass, and retrying the same index against every parked AU would burn the whole backlog for nothing; the loop comes round again on the housekeeping wake within 5 ms if it was transient.

enricobuehlerandClaude Opus 5	20de58a78a	fix(android/present): the panel grid can be wrong in both directions, and the margin listens to the latch ... Three defects in the 0.23.0 timeline presenter, all found while root-causing the field report that turned out to be the slice wire. None of them is that bug; all three are real, and the first is the one that would still bite once it is fixed. The panel-period learner could only ever narrow. It is seeded from the display mode Kotlin asked for — and `preferredDisplayModeId` is a REQUEST the system may refuse (Smooth Display off, battery saver, thermal, an OEM governor). Ask for 120 Hz on a panel that stays at 60 and the presenter pins an 8.33 ms grid on a 16.67 ms display with no way back, for the rest of the session: it then aims at instants that never arrive and releases faster than the panel scans. The learner moves both ways now, and lives in `punktfunk_core::phase::PanelGrid` where it is host-testable and where the iOS and desktop presenters can share it. The asymmetry is kept and made explicit — narrowing is immediate (a finer real grid is always safe to subdivide onto, and it is the per-uid down-rate case the seed most often gets wrong), widening needs eight consecutive agreeing observations and then takes the narrowest of them, because one wide sample is a missed callback and eight in a row is a display that really did slow down. The glass budget was a prediction with nothing underneath it. `OnFrameRendered` already reports what actually reached glass, but the budget never consulted it, so a wrong grid could hand SurfaceFlinger frames indefinitely: BufferQueue fills, MediaCodec runs out of output buffers, the decoder stalls, and the no-output backstop starts begging for keyframes. Releases are now counted against their confirms and the presenter holds back past six outstanding — loose on purpose, since the callbacks are allowed to arrive batched and a held frame in the newest-wins slot is a dropped one. It self-clears when the confirms catch up, and writes the ledger off after the same 100 ms the stale reopen uses, so a platform that stops confirming can never wedge the stream. `qWait` and `unconfirmed` join the 1 Hz pf.present line, which is what would have made this visible from a log. The adaptive latch margin widened on `paced_drops` — the newest-wins store's own policy evictions, which happen whenever the stream out-runs the panel and say nothing about SurfaceFlinger's latch lead. On a healthy device that walked the margin to its 2.5 ms ceiling and re-imposed the display latency the P2e sweep had just measured away. It now widens on the measured latch exceeding one panel period plus the live margin, which is what a missed vsync actually looks like. Also corrects two doc comments that named `display.refreshRate` as the panel_hz source; it has been the mode table since the A024 down-rate fix. Gates: 278 punktfunk-core lib tests (7 new PanelGrid cases incl. the refused-mode regression), clippy -D warnings and fmt clean, cargo ndk check green on arm64 and armv7. Android clippy reports the same 4 warnings as the base commit and no new ones. NOT yet confirmed on glass.

enricobuehlerandClaude Opus 5	97b2c01ac1	fix(core/packet): a slice-streamed frame costs its own size, not the whole frame ceiling ... The 0.23.0 slice wire flushes a block every MIN_STREAM_BLOCK_SHARDS, so every ordinary access unit is now opened by a SENTINEL — a header with no totals. The reassembler sized those frames at `max_frame_bytes`, which the QUIC handshake clamps to 8-64 MiB. That was survivable while sentinels were rare (the streamed path emitted one only for an AU exceeding a whole FEC block, ~281 KB); it is not survivable now that every frame is one. Two consequences, both measured: each access unit allocated and ZEROED a multi-megabyte buffer, and the in-flight budget (IN_FLIGHT_BUF_FACTOR x max_frame_bytes) was spent after ~3 concurrent frames — with production geometry, 12 ordinary AUs in flight lost 9 of them outright, every packet dropped before it could be placed. On a link with normal reorder that is a permanent loss storm: frames never complete, the re-anchor gate freezes the picture, and the client begs for keyframes. Only clients advertising VIDEO_CAP_MULTI_SLICE reach this path — Android and the Linux/Windows session client; Apple and the Windows in-process client never did, which is why it read as a platform-specific "video pipeline" fault in the field. A sentinel carries no total but does pin its own block's extent: a slice sentinel by its wire base, a legacy one by its full-K position. Size the buffer to that and grow as later blocks (or the final block's totals) reveal more. The budget is re-checked on growth for the same reason it is checked at open. The same flush also drained `pending` to empty whenever the AU's length was an exact multiple of the shard payload, leaving `finish_streamed` to seal a final block of one zero-padded FILLER shard. Its derived base overlapped the block flushed a moment earlier, retro-validation correctly read that as a lying header, and the whole AU died — one frame in every 1408 on a 1500-MTU link, ~12 s apart at 120 fps, each costing a freeze and a recovery keyframe. A flush now keeps one whole shard back, restoring the invariant `StreamedAu::pending` already documented. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-02 20:15:45 +02:00

enricobuehlerandClaude Opus 5	b6acbd096e	fix(host/vdisplay): waking the PC stops failing the first session ... A woken Windows host refused every connection with "pf-vdisplay driver interface not found", on a box where the driver was installed and running. Resuming re-enters D0 and re-registers the IddCx control interface while the rest of the resume storm is still going. A client reconnecting a second after wake lands inside that gap. `ensure_available` probed exactly ONCE, so it read the gap as a dead driver and answered a device that was seconds from ready by disabling and re-enabling it — then gave the interface 4 s to come back, which a contended post-resume PnP does not meet. The session failed, and the log blamed a missing install. The recovery also could not tell whether it had recovered anything. It ran the whole cycle under `SilentlyContinue` and reported `(Get-PnpDevice).Status` — the DEVICE's status, not the cycle's outcome — so a disable that was REFUSED left the adapter untouched, started, and reading `OK`. That is the reporter's `cycled the adapter device … status=OK` line: a recovery that never happened, announcing success. And a refusal is the expected case here, not the exotic one: reset-pf-vdisplay.ps1 stops the host service first precisely because the host holds the driver's control device open, a step an in-process cycle structurally cannot take. - Distinguish a devnode MID-TRANSITION (interface registered, not started yet, or the open refused) from one genuinely ABSENT. Wait the first out; only the second earns a reload. `Probe` carries the counts. - Report what the reload DID, not what the device looks like afterwards: every failable step is `-ErrorAction Stop` in a `try`, and `pnputil /restart-device` is the fallback for the in-use device that `Disable-PnpDevice` refuses. Failure paths re-enable, so a half-cycle can never strand the adapter DISABLED. - Give the interface 15 s to arrive after a reload, not 4 — under a 30 s hard ceiling so a permanently wedged devnode still fails predictably. - Serialize recovery: N sessions racing in after a wake perform ONE reload, not N interleaved ones. The lock is taken only where no manager lock is held, so the order stays one-way. - Retire the manager's cached control handle when a reload runs, instead of letting the next session discover it via a failed IOCTL. - Surface the real reason. `ensure_available` returns `Result`, so the log names how long it waited, whether a reload ran, and how many interface instances were seen in what state — the detail that would have identified this from the field report's log alone. `VdisplayDriver::open` now shares the wait (brief, no reload) instead of carrying a second, drifted copy of it — that path is also reached by `hw_cursor_capable` mid-handshake, where a reload would be the wrong trade for one capability bool. Windows-gated, so verified with scripts/xcheck.sh (check + clippy -D warnings, --all-targets) and cargo fmt; on-glass wake test still owed.

enricobuehlerandClaude Opus 5	d63e913f52	fix(client/ios): Escape keeps the pointer captured instead of handing it back to iPadOS ... iPadOS releases the scene's pointer lock by itself when Escape is pressed — the platform's built-in "let me out", mirroring the web Pointer Lock API's default unlock gesture. Nothing in our code does it: a bare Esc never touches `captured`, and it keeps forwarding to the host as the game key it is. But the lock going away flips the mouse onto the absolute UIKit path and un-hides the iPadOS cursor, so pressing Esc for an in-game menu silently cost the capture until the user clicked into the video to win it back. Esc is a GAME key in a stream, not a request to hand the pointer back to iPadOS, so an unwanted drop is now re-requested. `syncPointerLock` arms a short, bounded burst (3 attempts over ~0.6 s, no restart inside 2 s) whenever the lock is wanted, was previously HELD, and is now gone; the first attempt re-asserts `prefersPointerLocked`, later ones present a real false→true transition and re-anchor the PointerLockChain. Every deliberate release (⌘⎋, ⌃⌥⇧Q, the Stream menu, resigning active) clears `captured` first, so `wantsPointerLock` is already false when their drop is observed and none of them are fought. The "previously held" half of the condition keeps a scene that never qualifies (Stage Manager, Split View) from paying for a lock that isn't coming — there, a first grant is still driven by the chain engage in setCaptured/viewDidAppear exactly as before. While a re-lock is in flight the local cursor stays hidden and absolute pointer MOTION stays muted, so the couple of frames it takes read as "Esc did nothing to my mouse" rather than a cursor that blinks in and out and a host cursor that teleports to the pointer's absolute position. Buttons still forward (they carry no position), so a click mid-relock isn't swallowed. The burst clears itself on give-up, so the cursor can never stay hidden on a lock the system won't grant.

enricobuehlerandClaude Opus 5	362595b20f	fix(vdisplay/kwin): the streamed output declares it mirrors nothing, so a stored replicationSource can't clone a panel into the stream ... KWin stores output configuration per *setup* — the exact set of connected outputs, matched by EDID/connector — in `kwinoutputconfig.json`, and `replicationSource` is one of the fields it saves and restores (`OutputConfigurationStore::storeConfig` / `setupToConfig`). Our virtual output carries a STABLE name on purpose, so once any setup has an entry making `Virtual-punktfunk` a mirror of a physical head, KWin re-applies it to OUR output on every session that reproduces that same monitor set — and only that set, which is why the failure looks environment-dependent: a field report has the stream cloning the panel whenever exactly one monitor is live, and behaving normally the moment the others come back (a different setup key, a different stored entry). A mirroring output is not a desktop. KWin's `applyMirroring` overrides its scale and render offset to the source's, so the stream carries the physical screen's viewport at the physical screen's size instead of the mode the client negotiated. The protocol says the rest out loud on `priority`: "an output may not be in the output order if it's disabled or mirroring another screen" — so the primary assertion this module works so hard to verify silently stops meaning anything too. Nothing we sent ever contradicted the stored value. The topology config enabled our output, took priority 1 and disabled the others, but never stated the one property that decides whether the thing is its own screen. Now it does: `set_replication_source(ours, "")` rides along in the config we already build (free, idempotent — an empty source is exactly what KWin resolves to "mirrors nothing"), gated on management v13 where the request appeared, since wayland-rs does not range-check requests and an out-of-range opcode would kill the connection. `extend`/`auto` issue no topology calls by design — the streamed output is meant to join the desk without rearranging it — but a mirror is not an arrangement, it is a broken source under every topology. So they get `clear_replication_source`, which enumerates and applies ONLY when our output really is mirroring. The device's `replication_source` event is now read, so the state is visible: a mirrored streamed output names its source in a warn instead of leaving "the stream just shows my monitor" as something only the reporter can see. Verified on 192.168.1.25 (Ubuntu, cargo 1.96): `cargo test -p pf-vdisplay` 128 pass (7 in `kwin_output_mgmt`), `cargo clippy -p pf-vdisplay --all-targets --locked -D warnings` clean, `scripts/xcheck.sh linux` clean, fmt clean.

enricobuehlerandClaude Fable 5	caa47e28e6	fix(client/decode): AV1 hardware decode stops silently opening libdav1d ... avcodec_find_decoder(id) returns the registry's FIRST decoder for the id, and upstream orders the native av1 decoder LAST on purpose ("hwaccel hooks only, so prefer external decoders" — allcodecs.c). All three hardware backends selected by id, so every AV1 session opened libdav1d: a software decoder that silently ignores hw_device_ctx and never calls get_format. Each frame then failed the backend's hw-format guard and the session burned the demotion ladder MID-STREAM — field-logged as 68 Vulkan fails → D3D11VA → 102 fails → software, ~3 s of black — with "hardware decode active" already printed and the D3D11 profile/pool probes all green. H.264/HEVC never hit this only because their native decoders happen to be registered first. Selection is now by capability: find_hw_decoder walks av_codec_iterate and takes the first decoder whose avcodec_get_hw_config advertises the backend's surface via HW_DEVICE_CTX, so a build without a usable hw decoder fails at OPEN in milliseconds and the ladder runs there — the idiom the D3D11 probes already follow. Registry order still wins among capable decoders, so H.264/HEVC select exactly what they always did. The software path keeps the id lookup on purpose: libdav1d is the fastest CPU AV1, and the native av1 decoder has no software path at all. Every decode log now carries the selected decoder's name — decoder="av1" vs decoder="libdav1d" is the whole diagnosis, and no log line said it. The session log names the WIRE codec and drops the FFmpeg id for PyroWave (ffmpeg_codec_id's fallthrough claimed codec_id=HEVC for wavelet sessions that never touch FFmpeg). The CPU lane also stops passing raw PQ off as a tone-map: software-decoded frames deliberately never take the HDR10 swapchain, but a PQ stream there was then shown UNtonemapped (washed out) with no warning — the pq-downgrade warn keys off the swapchain answer — while the Detailed OSD badge claimed the "HDR→SDR" tone-map that only the hardware lane's CSC runs. The presenter now warns once when a PQ CpuFrame arrives, and the badge distinguishes "HDR→SDR (raw)" (no tone-map pass) from the hardware lane's real "HDR→SDR".

enricobuehlerandClaude Fable 5	652abeb397	fix(host/audio): an unsatisfiable wiring plan waits for an endpoint change instead of hammering ... Field case 2026-08: the display isolate invalidated the only real render endpoint; the mic held the Steam Streaming Microphone, the Speakers were blacklisted, and the capture loop re-ran the full wiring pass — three IPolicyConfig SetDefaultEndpoint writes included — every 2 s for 8+ minutes, retrying a verdict that could never change. - wiring_plan: a plan with no loopback is a typed structural verdict (Wiring::loopback_unsatisfiable + an endpoint-set fingerprint); the dead leftover() tier (byte-identical to real_hw()) becomes a real last resort that accepts ONLY the Steam Streaming Speakers, flagged loopback_last_resort — a known-silent-loopback QUALITY risk, never the cable/VoiceMeeter echo CORRECTNESS risks. excluded_from_loopback stays untouched (judge_default's mid-stream snap-back semantics). - wasapi_cap: an unsatisfiable plan errors ONCE per topology with the render inventory, per-endpoint rejection reasons and only the remedies not already taken, then parks on a cheap enumerate-and-hash poll and re-plans the instant the set changes; transient failures get a real capped exponential backoff (2 s → 60 s, reset on success or set change); a last-resort capture re-plans on any set change and promotes the 30 s zero-packet breadcrumb to warn. - audio_control: the recording default is asserted only when the plan changed or the default drifted — set_default_endpoint fires all three SetDefaultEndpoint roles unconditionally, so the 2 s loop silently stomped any operator recording-device change; the "attach one, or let the host install the Steam Streaming pair" warn (already satisfied in the field case) is replaced by the same diagnosis. Verified: 19/19 wiring_plan tests (native rustc --test and the Linux CI image via docker); both Windows files type-check and clippy clean against wasapi 0.23.0 / windows 0.62.2 for x86_64-pc-windows-msvc via an xcheck-style stub harness (the in-tree target check dies in openh264-sys2's build script on macOS, as scripts/xcheck.sh documents).

enricobuehlerandClaude Fable 5	48511d1267	fix(abr): probe throughput is measured over the client's receive interval ... The capacity probe divided client-side bytes by the HOST's burst duration — a window wrong on both edges (base snapshotted before the burst reached the host, frozen only when the ProbeResult landed, while the host's clock stops the moment ITS send window closes, before the switch/kernel queue finishes draining toward the client). On a 1 GbE link a 2 Gbps burst target "measured" 1266 Mbps and set an 886 Mbps climb ceiling the link could never carry — permanent for the session, because set_ceiling never lowers. The reassembler now stamps probe-scoped counters (bytes, packets, first/last arrival, monotonic ns) at its FLAG_PROBE routing, so video around the burst contaminates neither numerator nor denominator; the throughput divisor is the client's first→last arrival interval, with the host duration kept as the fallback when fewer than two probe packets arrived. The user-facing speed test shares the corrected computation (ProbeOutcome/PunktfunkProbeResult layouts unchanged; elapsed_ms docs updated to the new semantics). Two guards ride along: - PUNKTFUNK_ABR_MAX_MBPS clamps inside set_ceiling — the one funnel every learned ceiling passes through — so a user cap binds no matter what any probe concludes. - The controller latches decode_cap_kbps when two CONSECUTIVE backoffs carry decode-severe evidence (deep decode excursion or jump-to-live flush) at a similar pre-backoff rate, mirroring host_cap_kbps for the client decoder: a knee below the link ceiling was a permanent 30-60 s sawtooth costing a flush + dropped-frame burst per cycle (1440p120 HEVC field case, knee ~490 Mbps). One spurious flush never latches; the cap re-probes on the CAP_REPROBE_WINDOWS clock, so it lifts when the decoder recovers. Also rights the three stale "3 Gbps" probe-clamp comments (the host constant has been 10 Gbps since MAX_PROBE_KBPS moved).
