- Replaced the miniaudio dependency with custom OS audio device abstractions and backends.
- Implemented platform-specific audio playback and capture for macOS (Audio Queue), Windows (WASAPI), and Linux (PulseAudio/ALSA).
- Added a fallback stub backend returning errors for unsupported platforms.
- Updated audio stream handling with reliable fill guard wakeups and streamlined rate validation.
Runtime: the loader's AVX2 probe used [System.Runtime.Intrinsics.X86.Avx2]
via powershell.exe, which only exists on .NET Core — stock Windows PowerShell
5.1 raised TypeNotFound, so every Windows host silently loaded the baseline
addon and paid ~270ms for the spawn on the startup path. Ask the kernel via
bun:ffi (IsProcessorFeaturePresent(PF_AVX2_INSTRUCTIONS_AVAILABLE), ~0.5ms)
and fall back to pwsh-then-powershell for Node embeds. scripts/host-detect.ts
shared the same broken probe for build-time variant selection.
Build: `bun run build:native` on a win32 host died deep inside the bazel msvc
repo rules (linux/mac exec hosts only, by design). The `host` pseudo-target
now delegates to the local napi build against real VS Build Tools, and other
targets fail fast with guidance. build-bindings.ts resolves the @napi-rs/cli
JS entry from its manifest (the node_modules/.bin shim is a PE launcher Bun
cannot parse) and auto-appends VS Build Tools' bundled CMake/Ninja to PATH
via vswhere so a vcvars prompt is no longer required. Cap maudio at
opt-level=1 to dodge a rustc ICE codegenning MaybeUninit<ma_fence> for
x86_64-pc-windows-msvc under the pinned nightly (Bazel's older pin is
unaffected).
Compile: Bun.Glob.scan yields backslash paths on Windows; the legacy Pi
virtual module used them verbatim for export keys and generated identifiers,
producing invalid JavaScript in compiled-binary builds.
Tests: strip ConPTY negotiation escapes in the pty argv test; ignore the
bazel-oh-my-pi convenience symlink.
- Added native `FileLock` bindings supporting cross-process advisory locking on Linux, Unix, and Windows.
- Replaced directory-based file locking and custom stale-lock reclamation with OS-backed native locks.
- Updated TypeScript declarations, native bindings, and package documentation for the new API.
- Added comprehensive unit tests and fixtures validating single-owner constraints and process death handoff.
- Replaced monolithic desktop native bindings and action batching with a modular cross-platform backend structure supporting Wayland, X11, macOS, and Win32.
- Updated the computer tool schema and supervisor to execute persistent JavaScript script runs with timeout clamping and asynchronous tool calling.
- Integrated accessibility (AX) tree snapshotting, node querying, and bounds-based hit testing across platform desktop layers.
- Added native clipboard bindings and updated coding-agent prompts, renderers, and tests to validate script-based computer workflows.
- Added window discovery, targeting, and frame validation for macOS, Windows, and Linux platforms.
- Updated computer tool and protocol definitions to support listing and targeting specific application windows.
- Refactored native computer tool exposure to function-only representation across models.
- Updated documentation and test suites to reflect window-scoped computer control capabilities.
- Replaced the napi-cli/cargo-zigbuild/cargo-xwin/sccache build path with
Bazel: rules_rust + crate_universe over Cargo.lock, hermetic zig cc
toolchains (linux-gnu pinned to glibc 2.17, linux-musl), host Xcode for
darwin, and a repo-local hermetic clang-cl + llvm-ml + xwin toolchain for
windows-msvc (bazel/toolchains/msvc).
- All eight shipped addons build as //:natives-<target> via the release
transition in bazel/defs.bzl (opt, thin LTO, cgu=16, stripped, canonical
.node naming); scripts/bazel-natives.ts is the single driver for local
dev and CI.
- Rust validation moved to bazel test + clippy aspects (strict workspace
policy for opted-in crates, default lints elsewhere, mirroring cargo
semantics) and the rustfmt aspect; cargo stays as the dev-iteration
surface, with brush-core/brush-builtins promoted to workspace members
and excluded from cargo dev tasks to keep their historical scope.
- CI caches through an in-cluster bazel-remote action cache (TLS + basic
auth, cluster-internal only); GitHub-hosted runners never touch the
infrastructure and use an actions/cache-backed disk cache instead.
- Deleted the hand-rolled caching machinery: ci-target-cache,
ci-native-artifact-cache, ci-build-native, native-source-hash,
find-native-artifacts, restore-linux-native, native-prewarm workflow,
ensure-* toolchain actions, and all sccache/Swatinem wiring.
- Warm native rebuilds drop from ~20 minutes to seconds; a cold client
with a warm remote cache rebuilds the linux x64 pair in ~2.5 minutes.
- Remove uniform language inference requirement, allowing mixed-language paths to rewrite each file in its own language.
- Update `ast_edit_blocking` in `crates/pi-natives/src/ast.rs` to compile rewrite rules per language and skip unsupported languages gracefully.
- Update `ast-edit.md` prompt documentation to reflect mixed-language path support.
- Add test coverage verifying mixed-language tree rewrites.
- Switched from `miniaudio` to `maudio` Rust crate and added `AudioCapture` and `AudioPlayback` native classes.
- Removed browser-side audio infrastructure including Web Audio API, audio worklet processor, and WebRTC runtime.
- Migrated STT recorder and transcriber modules to use native `AudioCapture` with callback-based streaming.
- Replaced streaming audio player with native `AudioPlayback` that writes PCM directly without TypeScript intermediaries.
- Removed ffmpeg, wav, and platform-specific playback commands from the audio toolchain.
- Replaced puppeteer-based WebRTC with native LiveWebRtcPeer for cross-platform live audio delivery.
- Added cross-platform microphone capture via miniaudio and Opus codec integration for live encoding/decoding.
- Added Apple DeviceCheck attestation token generation via raw Objective-C FFI for macOS.
- Updated live session model to "gpt-live-1-codex" and default voice to "sol" across protocol and controller.
- Added LiveWebRtcPeer and deviceCheckGenerateToken to the public native bindings API.
- Replaced the separate GUI-linked pi_natives.desktop.linux-x64 addon with
a pure-Rust X11 backend (x11rb RustConnection capture via RandR/GetImage,
XTest input with keysym mapping) compiled into the core addon on every
published target; Linux arm64 and musl are now supported and headless
hosts load the addon unaffected.
- Removed the native-desktop-linux cargo feature, desktop_unsupported.rs,
lazy desktop loader, second napi build, desktop packaging/CI steps, GUI
build dependencies, and the now-unreferenced vendored libspa crate;
reverted setup-system-deps to main.
- Preserved the desktop input hardening semantics on the unified backend:
XTest layouts reject negative origins and coordinates beyond 0..=32767,
batch coordinates stay bound to the frame last returned to JS with
intermediate screenshots deferred, coordinate input requires a
previously returned frame, and failed chord releases still release
every held key.
- Enforced a 60s worker-side execute deadline (DESKTOP_DEADLINE_EXCEEDED):
no input is emitted after expiry and wait-heavy batches are rejected
upfront.
- Added int32 fail-closed validation for coordinates, drag points, and
scroll deltas at the JS ingress and gateway schema.
- Exposed computer to models without native OpenAI computer-use support as
a regular function tool with a typed GA action schema across OpenAI,
Azure, and Codex Responses providers, including named forced choice.
- Added the /computer slash command (on/off/status/toggle) for
session-only enablement via runtime tool registration in SessionTools.
- Updated docs, changelogs, and contract tests accordingly.
- Implemented native UTF-16 text processing in Rust diff module with support for unpaired surrogates.
- Removed `similar` crate from Rust workspace and `diff` npm package from coding-agent, hashline, and natives.
- Removed jsdiff fallback wrappers and `isWellFormed()` guards from TypeScript diff implementations.
- Added comprehensive test suite for native diff functions covering random inputs and edge cases including surrogates and emoji.
- Renamed model `codex-auto-review` to `gpt-5.3-codex-spark` with updated pricing and context window.
