The §5.1 dry-run audit gate passes. All 13 rows completed with a non-empty eligible half in every one, and O5 is re-measured on the fixed graph: worst recompute 67 µs across every run, 10 µs mean under deliberate churn, busy fraction 0.0006, readiness 1-2 ms with 18 binds against a 2000 ms budget. Round 10's finding, and it is the third of exactly the same shape: the pipewire-pulse PID derivation required a SINGLE repeated pipewire.sec.pid. WirePlumber repeats one too (two Clients, both sec_pid 1747), so the derivation returned None permanently on a stock desktop, key 4's suppression never fired, and every Pulse-emulated node fused into one owner. Row 1's CLEAN control forwarder and Firefox were both excluded. Fixed in pixelpass 91c4ded by deleting the heuristic: probe every distinct sec_pid and let /proc/<pid>/comm decide. Three measured rounds now, all at the observation boundary, none in the architecture -- and all three were fail-closed and silent, caught only because §5.1 requires asserting what must remain ELIGIBLE. An exclusion-only checklist would have passed every one of these builds. Rows 4-6 are closed through peerspeak's REAL tagging sites (call, mpv, notify, plus clip) with a hand-launched mpv staying eligible, so the cross-repo contract is proven end to end on live nodes. Row 10 covers the full sticky lifecycle including retirement; row 11 is provably non-vacuous (the recycled node.link-group came back byte-identical and did not inherit taint). Recorded and NOT claimed as passes: substitutions in rows 8, 9 and 13, and two reporting-only findings (the audit's sticky flag is uninformative; a bridge's named key is lost when a leg reappears under a new serial). Phase 6 remains blocked by F11-1, phases 0b/0c/0d and the Stereo Mix design call -- this file removes one gate, not all of them.
PeerSpeak
Decentralized, peer-to-peer voice chat — full-mesh, NAT-traversing, with no central server. Built in Rust on iroh (QUIC), PipeWire audio, the Opus codec, and an iced GUI.
Create a room, share the join ticket, and talk. Everyone connects directly to everyone else; relays are only used to punch through NATs when a direct path isn't available.

Features
Rooms & sessions
- Create a room → shareable join ticket; join by pasting a ticket.
- Full-mesh multi-peer rooms with live presence.
- Recent-rooms list to hop back into a room someone's still in.
- Remembered nickname and in-call duration timer.
Audio
- PipeWire capture/playback, selectable input and output devices, per-app gain.
- Opus codec (48 kHz mono, 20 ms frames) with an adaptive jitter buffer + packet-loss concealment.
- Noise gate with a draggable threshold on a live mic meter (test your mic off-call too).
- Mix-bus soft limiter and opt-in echo cancellation (PipeWire WebRTC AEC + noise suppression).
Voice controls
- Self-mute, deafen, and rebindable push-to-talk.
- Per-peer volume, local mute, and speaking indicators.
Text chat
- In-room text chat over the gossip plane, with clickable links and inline image/audio attachments.
- Drag-selectable, copyable messages; right-click context menu on all text fields.
Shared music listening
- Build a personal playlist of local audio files with a full transport (play/pause, seek, reorder).
- Let others tune in: peers stream your current track, timeline-synced and gapless, sitting under voice at their own volume.
Screen share (via pixelpass)
- Share your screen; peers click 👁 Watch to open the stream in mpv (vlc fallback).
- Live badges on sharing peers; per-app audio capture.
Recording & notifications
- Local call recording (mic + incoming mix → WAV in
~/peerspeak-recordings/). - Desktop notifications and event chimes with per-event custom sound overrides.
UI & networking
- Selectable room layouts (3-Column, Bottom Dock, Drawer) with draggable, persisted dividers.
- 10 built-in themes (Catppuccin, Dracula, Nord, Tokyo Night, Gruvbox, Solarized…), all WCAG-AA checked.
- Network mode picker (relay-no-discovery default, full n0, or direct-only); retained-address reconnect.
- Config, window size/position, and all preferences persisted to
~/.config/peerspeak/.
See docs/FEATURES.md for the full inventory and field-test status, and docs/ARCHITECTURE.md for internals.
Roadmap
- Contacts & invites — friends list with invite-notification one-click join (design in
docs/contacts-plan.md). - Spatial audio & per-peer EQ.
- Soundboard — play short clips into the call mix.
- Room persistence / invite links beyond the raw ticket.
- Windows support — cross-compiles and launches under Wine today; needs a real WASAPI audio pass (see
docs/WINDOWS.md).
Building
PeerSpeak builds with a stable Rust toolchain (edition 2024). Install the system dependencies below, then:
cargo build --release
./target/release/peerspeak
System dependencies
Arch Linux
sudo pacman -S --needed rust pipewire opus pkgconf git
Debian / Ubuntu
sudo apt install build-essential pkg-config clang libclang-dev \
libpipewire-0.3-dev libopus-dev libasound2-dev libxcb1-dev
Plus a Rust toolchain via rustup. clang/libclang are needed for the PipeWire bindings (bindgen).
At runtime you need a running PipeWire server. Screen sharing additionally requires pixelpass on your PATH, and mpv (or vlc) to watch a peer's share.
Packaging
- Arch:
cd packaging && makepkg -si(usespackaging/PKGBUILD). - Debian/Ubuntu:
.debis built withcargo-debfrom the[package.metadata.deb]block inCargo.toml. Build inside a Debian/Ubuntu environment so the binary links that distro's glibc. - Windows: see
docs/WINDOWS.md.
