molluskandClaude Opus 4.8 47c58047ce Windows port Phase 1: real cpal/WASAPI audio backend
windows-build / windows-build (push) Has been cancelled
cargo-deny / cargo-deny (pull_request) Has been cancelled
windows-build / windows-build (pull_request) Has been cancelled
Replace the Phase 0 no-op CpalBackend stub with a working cpal backend
(WASAPI on Windows), preserving the exact PipeWire AudioBackend contract
so the mixer/encoder/jitter pipeline is unchanged.

- Capture: input stream -> downmix to mono -> 960-sample (20ms) i16 frames
  -> tx, matching the encoder/jitter frame size.
- Playback: 200ms stereo ring prefilled to PLAYBACK_TARGET_SAMPLES; the
  output callback drains it (silence on underrun) while the owning thread
  feeds it from rx. ring_fill is the exact delta-maintained occupancy
  counter (fetch_add on push, fetch_sub on pop), preserving the clock-paced
  production design (not ringbuf's stale occupied_len).
- cpal::Stream is !Send, but AudioBackend is Send+Sync and shared via Arc,
  so each stream lives on its own owning thread (built/played/dropped
  there); the struct holds only the running flag + JoinHandle. stop()
  flips the flag and joins.
- Generic over F32/I16/U16 sample formats; device selected by name else
  default; requires a native 48kHz config (clear error otherwise, no
  resampling yet). Mirrors the PipeWire drain_loop and playout-health line.
- Cargo.toml: add cpal 0.15 under cfg(windows).

Verified by temporarily compiling cpal_impl against real cpal on Linux/ALSA:
build + clippy clean, 6/6 cpal_impl unit tests pass. Reverted to windows-only
gating; shipped Linux state green (316/316). Runtime/WASAPI end-to-end is
unverified and pending a Windows host (plan M2).

molluskandClaude Opus 4.8 85b12a26c9 Windows port Phase 0: platform-select the audio backend
windows-build / windows-build (push) Has been cancelled
cargo-deny / cargo-deny (pull_request) Has been cancelled
windows-build / windows-build (pull_request) Has been cancelled
Make the tree compile for Windows without touching core logic, by
confining all Linux/PipeWire assumptions behind cfg gates and a single
platform-selected backend alias. No new dependencies — the cpal/WASAPI
backend lands in Phase 1; this ships a no-op stub.

- Cargo.toml: move pipewire + rfd(xdg-portal) under cfg(unix); add a
  cfg(windows) rfd using the Win32 dialog backend.
- audio: gate pipewire_impl to unix, add a cpal_impl stub for windows,
  and select between them via the new PlatformAudioBackend alias.
- core: use PlatformAudioBackend instead of the concrete PipeWireBackend.
- lib: gate the unix-only 0o600 log-file mode code (+ its test); Windows
  logs inherit the directory ACL.
- audio_probe: gate this PipeWire diagnostic to unix with a stub main.
- app: open URLs via rundll32 on windows, xdg-open on unix (shell-free).
- ci: add .gitea/workflows/windows-build.yml (M1) — build + lib tests for
  x86_64-pc-windows-msvc, with CMAKE_POLICY_VERSION_MINIMUM=3.5 for the
  vendored libopus build. Needs a windows act_runner to actually run.

Linux build/clippy/tests green (316/316). The Windows path is verified by
inspection only (no local Windows toolchain); CI is the real gate.

name: windows-build
# Milestone M1 of the Windows port (see docs/handoff windows-migration-plan):
# prove the tree compiles for `x86_64-pc-windows-msvc` and the unit tests pass.
# The audio backend is the Phase 0 `CpalBackend` stub for now — this job guards
# the *compile* boundary (cfg gating, platform deps, the PlatformAudioBackend
# alias) so a Unix-only assumption can't sneak back in and break Windows.
#
# RUNNER REQUIREMENT: this needs a Windows act_runner registered with the
# `windows-latest` label (the Linux `cargo-deny` job's container approach does
# NOT apply here — Windows jobs run on the host, not a Linux container). If your
# runner advertises a different label, change `runs-on` below. Until a Windows
# runner exists this workflow is simply skipped/queued, not a failure of the
# Linux CI.
#
# BUILD-HOST REQUIREMENTS (validated by the opus spike, see
# peerspeak-windows-opus-spike.md):
# - MSVC C toolchain (Visual Studio Build Tools) — to compile vendored libopus.
# - CMake on PATH — `audiopus_sys` builds libopus from source via cmake.
# - CMAKE_POLICY_VERSION_MINIMUM=3.5 (set below) — the vendored libopus declares
# an ancient `cmake_minimum_required` that CMake >= 4.0 refuses without it.
# GitHub-hosted `windows-latest` images ship MSVC + CMake; a self-hosted runner
# must provide both.
on:
push:
# `main` plus the in-progress port branches, so the Windows path is exercised
# before merge rather than only after.
branches: [main, "windows-port-**"]
pull_request:
# Allow manual runs from the Gitea Actions UI.

//! Windows audio backend — cpal / WASAPI (Phase 1).
//!
//! Implements [`AudioBackend`] on top of [`cpal`], which wraps WASAPI on Windows.
//! It is the Windows counterpart to `pipewire_impl.rs` and deliberately preserves
//! the exact same contract so the rest of the app (mixer, encoder, jitter buffer)
//! is unchanged:
//!
//! - **Capture**: mono, 48 kHz, S16 PCM, emitted as `Vec<i16>` frames of
//! [`CAPTURE_FRAME`] (960 = 20 ms) samples — matching the encoder/jitter frame.
//! - **Playback**: stereo interleaved ([`PLAYBACK_CHANNELS`]) S16 PCM at 48 kHz,
//! drained from a ring buffer that is paced to the device's hardware clock via
//! `ring_fill` exactly as the PipeWire backend does.
//!
//! ## Threading and the `!Send` stream
//!
//! `cpal::Stream` is `!Send` (some backends require it to be created and dropped
//! on the same thread), but [`AudioBackend`] is `Send + Sync` and the backend is
//! shared through an `Arc`. So the stream never lives in the struct: each of
//! `start_capture`/`start_playback` spawns one owning thread that builds the
//! stream, plays it, and keeps it alive until the per-worker `running` flag flips
//! (set by `stop`). The struct holds only `Send` handles (the flag + the join
//! handle). The stream's RT callback does the actual audio work; the owning
//! thread additionally feeds the playback ring from the network mixer.
//!
//! ## Sample rate
//!
//! The whole pipeline assumes 48 kHz (Opus + the 960-sample frame). Phase 1 only
//! selects a native-48 kHz device config; if the device can't do 48 kHz we return
//! a clear error rather than silently producing pitch-shifted audio. Arbitrary
//! sample-rate support (resampling) is a Phase 1.1 follow-up.
