## What changed
- Add a `GstAudioSink` subclass backed by a bounded mono `F32LE` playback writer, with partial writes, cancellation on speaker epoch changes, and delay accounting for queued samples and pending device output.
- Recreate the CPAL output stream and discard buffered audio when speaker controls change the epoch, preventing stale audio from surviving suppression.
- Add GStreamer dependencies, adjust Windows Bazel native-tool selection, and allow the helper handshake time to load startup-linked libraries.
- Separate installed-client tests from protocol lifecycle tests and supply native startup libraries in test packages.
## Testing
Add unit coverage for partial writes, sample accounting, suppression cancellation, stale writers, device delay, invalid samples, and stalled consumption.

## What changed
- Add explicit x64 and ARM64 targets for native builds, runtime preparation, and linking using the existing voice recipes. Each target requires native Windows execution of the matching architecture.
- Declare compiler, SDK, Python, and CMake inputs; require an explicitly supplied Cygwin/pkgconf tool tree and a fixed `SystemRoot`. Validate installed tool selections against the manifest and declared files.
- Pair Windows DLLs with SDK import libraries, preserve plugin and receipt runfiles, and omit Unix runtime-search flags. Use Python for portable payload copying.
- Correct the MSVC ARM64 tool directory casing to `HostArm64` and document provisioning and build commands.
The generic Rust-consumer aliases remain separate; native Windows Bazel execution and consumer validation are still needed to establish complete Windows voice support.
## Testing
Add eight unit tests covering tool selection, path anchoring, invalid inputs, and DLL/import-library copying, plus x64 and ARM64 link smoke targets that reference `gst_version`.
GitOrigin-RevId: fb2b4998e9ffb5b64ca830ebf4bb4633fc959eb9
## Why
Windows libffi builds invoke tools by name, and Cygwin provides a different `link.exe` from MSVC. Inherited search paths can select unintended tools or SDK inputs.
## What changed
Add optional `--windows-build-inputs <json>` to `third_party/voice/build_native.py` to select installed tools and SDK directories for Windows MSVC targets. Validate the target, tool paths, architecture-specific assembler, SDK directories, and agreement with CLI tool arguments.
Build the search path from the selection with MSVC ahead of Cygwin, reject shadowed tools, replace inherited `INCLUDE` and `LIB`, and remove `LIBPATH`. Retain the selection in build receipts. Builds without the option continue using the normal Visual Studio environment.
## Testing
Add tests for linker precedence and subprocess selection, invalid or mismatched inputs, shadowed SDK tools, environment replacement, and receipt recording.
GitOrigin-RevId: c80a6d9eb29556157ba1316d62c9b5083f4038b9
## Why
The helper's native bindings require shared libraries before entering `main`, including for lifecycle calls. Helper-only packages cannot satisfy that requirement.
## What changed
Make `--runtime` mandatory in `third_party/voice/assemble_package.py` and require the `runtime` argument in `assemble()`. Always validate and include the prepared runtime, and update the voice host documentation to describe the requirement.
## Testing
Update assembly tests to supply prepared runtimes and verify that package manifests include runtime library hashes and `runtime.json` alongside the helper.
GitOrigin-RevId: ab5abf80ae935b4ace833fa59b74f670ba62c632
## What changed
- Export `native_sdk` from the same inspected build as `native_runtime`.
- Configure GLib and GStreamer Rust build scripts to use the declared `pkg-config` executable and SDK, preserving upstream version checks while directing linking to prepared libraries.
- Add `native_link` to expose canonical libraries, development aliases, transitive dependencies, plugins, and the runtime manifest through `CcInfo` and runfiles. Replace GStreamer SDK absolute rpaths with relative Bazel runpaths.
## Testing
Extend the macOS archive preparation test to cover absent and empty SDK output directories, verify SDK file hashes, and check that SDK and runtime manifests share the same source commit and target.
GitOrigin-RevId: 3fc33af06225c69e4c293437f1985290f228dc0a
## What changed
Add the manual `//third_party/voice:native_runtime` target for macOS and GNU Linux. It consumes the native prefix archive, validates the completed build receipt against the target and source manifest, inspects libraries, and prepares verified copies using the existing platform policies.
Record the build commit through Bazel workspace status and include it in runtime receipts. Reject invalid or ambiguous commit metadata and escaping library aliases. Keep macOS preparation local and allow the system `libc++.1.dylib` dependency.
## Testing
Add tests for receipt validation, inspection ordering and failures, invalid commit metadata, and escaping archive links. Add a macOS integration test for preparing real libraries from a sandbox-linked archive with native aliases and either an absent or empty output directory.
GitOrigin-RevId: 23717ab33d1d3da5fb0042c1cc8e8efcd333c386
## What changed
Add `//third_party/voice:native_prefix` to run the existing native build recipe with Bazel-declared archives and toolchain inputs on matching macOS and Linux GNU 2.28 targets for x64 and ARM64. The manual target exports `prefix.tar` and a `built.json` receipt through the `receipt` output group.
Keep macOS actions local to access Apple tools, use Apple's linker for libffi partial links, and preserve compiler runtime flags through libtool on Linux. Surface upstream build failure logs in the Bazel action output.
Document the build's host utility requirements and the distinction between the raw prefix and a relocatable SDK or runtime package.
GitOrigin-RevId: b4917943f621dec07bb994392619e8a42e496b8b
## Why
Native voice builds ignore ambient compiler flags, but need a way to accept declared compiler, linker, and archive-tool inputs.
## What changed
- Add repeated `--c-flag`, `--cxx-flag`, and `--link-flag` options plus optional `--ar` and `--ranlib` paths for Unix builds. Record flags and pass them through CMake, Meson, and libffi, including Objective-C flags on macOS.
- Preserve literal libffi compiler arguments with response files. Reject flags containing whitespace, libffi paths requiring shell quoting, and Unix toolchain overrides on Windows.
- Add a pinned Bazel `pkg-config` tool built with LLVM archive tools and native macOS configure checks. Register the pinned Make toolchain and patch its bootstrap to pass preprocessor flags and enable cross-compilation configuration.
## Testing
Extend native-build tests to verify compiler and linker flags, explicit archive tools, Meson and Objective-C inputs, literal definitions through shell and recursive Make expansion, and rejection of unsupported overrides.
GitOrigin-RevId: e5ea541ec76abfa170f6b0411b0f14cd698c07e7
## Why
The Rust GStreamer bindings link GLib's GIO library even when none of the selected plugins imports it. Following only plugin dependencies can omit a library the bindings need.
## What changed
- Export `gio-2.0` pkg-config metadata in the voice SDK.
- Require GIO as a runtime dependency root on Linux, macOS, and Windows, including its transitive dependencies under the existing import checks.
- Reject runtime packages that omit the required GIO library.
## Testing
Extend fixtures to cover GIO inclusion and missing-library rejection across platforms, loading GIO and its transitive dependency after moving a Linux runtime, and resolving `gio-2.0` through pkg-config after moving an SDK.
GitOrigin-RevId: d12e45d387d56c54d94d788cf07d82bb22c2b4a3
## What changed
Add `third_party/voice/sdk.py` to export headers, development libraries, and selected pkg-config metadata from an inspected native build. Verify shared libraries against inspection receipts and record the target, source commit, source manifest hash, and exported file hashes in `sdk.json`.
Enable relocatable Meson pkg-config metadata and materialize development library aliases. Reject mismatched receipts, paths escaping the build prefix, nonrelocatable metadata, and unsafe output locations; remove partial output on copy failure. Document SDK consumption as build inputs separate from packaged runtime files.
## Testing
Add tests for exported hashes and pkg-config resolution after moving the SDK and deleting the original prefix, alias materialization, invalid inputs, and cleanup after copy failure.
GitOrigin-RevId: 6d1575e659a02cd1f56e465e7830a296e8eaf486
## Why
The bundled Opus encoder uses CMake and should not depend on tools available on a build worker's `PATH`.
## What changed
- Add `rules_foreign_cc` and provide its pinned CMake and Ninja tools and data to the `opusic-sys` build script.
- Add a CMake toolchain file that selects the declared Ninja executable, resolves the archiver path, and sets the target system and processor from `TARGET`, while retaining Bazel's compiler, SDK, and linker inputs.
GitOrigin-RevId: 48580c506d088d8c76cce958589ff94da458bd79
## What changed
- Add an optional `--runtime` input to `assemble_package.py`.
- Validate the runtime receipt, target, source manifest, plugin inventory, paths,
and file hashes before copying only the declared runtime files.
- Preserve each platform's runtime layout and record the copied files and
`runtime.json` in the package manifest.
- Recheck hashes after copying and remove the new output if assembly fails.
## Testing
Add package assembly tests for Linux, macOS, and Windows layouts, invalid
receipts and paths, modified inputs, symlinked directories, and copy-time
changes.
GitOrigin-RevId: 8c9609af8ced406926707b2b0e1dcd6d2251f94b
## What changed
- Add an x64 and ARM64 MSVC runtime preparer that uses `dumpbin` to validate
PE32+ DLL metadata, selects the declared GStreamer plugins and dependency
closure, and copies them unchanged into a private `bin/` directory.
- Reject malformed or unsupported PE metadata, path-bearing imports, delayed
imports, managed DLLs, forwarded exports, undeclared dependencies, and
case-insensitive DLL identity conflicts.
- Keep `third_party/voice/sources.json` line endings stable across Windows
checkouts so native build receipts remain valid.
## Testing
Add native Windows tests for relocated DLL loading with a restricted search
path, receipt and digest failures, duplicate identities, malformed PE headers,
unsupported loader features, and cleanup after failed preparation.
GitOrigin-RevId: 5375f21fc54f5d597f3d4e5f8fbca3df307fa2a8
## Why
Native voice libraries need package-relative loader paths so a prepared runtime
can be moved without retaining references to its build prefix.
## What changed
- Configure CMake and GNU Linux Meson builds with relative runtime paths, while
also setting relocatable install names and paths for CMake libraries on macOS.
- Add a GNU Linux runtime preparer for x64 and ARM64 that validates bounded ELF64
metadata, selects the declared GStreamer plugins and dependency closure, and
preserves the `lib/gstreamer-1.0/` layout.
- Reject malformed ELF metadata, path-bearing imports, unsupported loader
dependencies, and native outputs that still contain incompatible runtime
paths.
## Testing
Add native tests for relative build paths, relocated library loading, dependency
and digest failures, malformed ELF inputs, and cleanup after failed preparation.
GitOrigin-RevId: ed94819b07d20214b56363446b64f765e08d75fa
## What changed
- Add a shared runtime preparer that validates native build receipts, source and
file digests, dependency closure, and output containment before copying the
required voice plugins and libraries.
- Add macOS-specific Mach-O inspection and relocation that removes build-time
runpaths, rewrites non-system dependencies relative to each loader, applies
development ad-hoc signatures, and records the resulting payload in
`runtime.json`.
- Close the state runtime explicitly in the clear-memories CLI test.
## Testing
- Add macOS tests covering relocation after the source prefix is removed and
fail-closed handling of invalid receipts, changed inputs, unsafe paths,
dependency conflicts, malformed Mach-O metadata, and failed transforms.
GitOrigin-RevId: 3be7a6fabf0135a57036cbb0a9a3e597096930fd
## Why
The root Python formatting pass only covered `scripts/`, leaving Python utilities elsewhere in the repository outside `just fmt` and `just fmt-check`.
## What changed
- Run the scripts Ruff formatter from the repository root.
- Exclude `sdk/python`, which has its own formatter pass, and `codex-rs/vendor`.
- Apply Ruff formatting to the newly covered Python files and update the formatter coverage test.
GitOrigin-RevId: 73ac82b8bb9c713d589724f6c4f926399febb513
## What changed
- Add `VoiceHost` to resolve the packaged voice helper, launch it with an
allowlisted environment, perform the protocol handshake, and enforce bounded
shutdown and process cleanup.
- Preserve native executable path encoding in the pipe process APIs.
- Add `third_party/voice/assemble_package.py` to create a fresh package copy
containing a target-compatible helper and a provenance manifest with file
hashes.
## Testing
- Cover installed helper lifecycle, build matching, missing and symlinked
helpers, non-UTF-8 package paths, environment filtering, package validation,
target pairing, and failure cleanup.
GitOrigin-RevId: f893074b36ae6bb9bcedc00fbe7af6bb72745f4c
## Why
Windows builds combine Cygwin build tools with native MSVC outputs. On ARM64,
Cygwin can run under x64 emulation, so inferred host details and untranslated
paths can select the wrong target or leak POSIX paths into native metadata.
## What changed
- Convert libffi source, prefix, and shell paths with `cygpath`, preserve
`USERPROFILE`, and pass explicit build and host targets.
- Configure libffi's MSVC and libtool environment to produce and install its
shared library and import library, including across recursive make calls.
- Reject libffi pkg-config output containing `/cygdrive/` paths and enable
Opus NEON support for `aarch64-pc-windows-msvc`.
- Document the additional Windows build prerequisites.
## Testing
- Extend `test_build_native.py` with Windows path conversion, x64 and ARM64
target configuration, recursive make flag propagation, pkg-config, and Opus
coverage.
GitOrigin-RevId: 12eb4ff83e141aa069abd68af4839f06e4c45b8f
## Why
The pinned voice source inputs can be prepared but do not yet provide compiled
native libraries for downstream integration.
## What changed
- Add `build_native.py` to build a shared-library prefix for the supported voice
dependencies on native x64 and ARM64 GNU/Linux, macOS, and Windows MSVC hosts.
- Require explicit toolchain inputs, isolate dependency discovery to the output
prefix, and record command logs and build state for provenance and failures.
- Expose the recipe and source inputs through `//third_party/voice:build_inputs`
and document its prerequisites, outputs, and integration boundaries.
## Testing
- `PYTHONSAFEPATH=1 python3 -m unittest discover -s third_party/voice -p 'test_build_native.py'`
GitOrigin-RevId: 132d93561a8e1bb178518f1248cf87d031060aae
## What changed
- Pin the GStreamer, codec, native library, and build-tool archives needed by
the native voice runtime, including their SHA-256 digests.
- Add lazy Bazel repositories and a manual `//third_party/voice:sources` target
for fetching and unpacking the pinned archives.
- Add an offline Python adapter that verifies archive identity and extraction
bounds, refuses existing output directories, cleans up failed preparations,
and records a completion receipt.
- Document that this stage prepares source inputs only; it does not compile or
link the libraries or enable voice.
## Testing
- Add unit coverage for digest failures, unsafe links, expansion limits,
cleanup after extraction failures, existing-output preservation, and systems
where archive links cannot be created.
