* fix(snap): build and verify payload from locked python inputs
* docs(snap): document locked inputs and artifact verification
* test(clipboard): isolate restore workers between tests
* test(packaging): tighten isolation and clarify snap audit guarantees
* fix(ci): run snap recipe tests on snap-only changes
A change to snap/snapcraft.yaml or snap/local/smoke-test.sh only matched
the snap filter, so the Python tests that guard the recipe (including the
portable whisper.cpp flags from #957) and the smoke script were skipped.
Match all of snap/ in the python filter, as scripts/ already is.

* fix(aur): gate source publication on attested sdists
Prepare and verify the canonical release source, build the exact PKGBUILD on Arch, and publish the gated artifact without further rewrites. Part of #701.
* fix(aur): isolate local gate and binary publication
Keep local gate distributions and diagnostics in a private workspace, preserving other build outputs and failed diagnostics. Publish vocalinux-bin after its own AppImage inputs without depending on the source gate or unrelated release jobs. Add regression coverage for both review findings.
* chore(deps): allow uv versions below 0.14
* fix(ci): align uv version and generated exports
* fix(dev): check Fedora build headers and AppImage GI bundle
Fail early with distro-specific native dependency hints before dev sync. Verify the AppImage's PyGObject installation and Python path after linuxdeploy, and report isolated GI import failures with actionable path diagnostics. Guard the CI uv pin and cover both preflights with tests.
* feat(build): add locked reproducible wheel gate
Build independently in clean source trees and virtualenvs, compare wheel bytes, and stage only verified canonical distributions. Safely clean recognized prior outputs on repeat runs.
Part of #701
* ci(release): verify wheel reproducibility before publishing
Run the shared gate in PR and tag workflows, preserve failure diagnostics, and keep verification artifacts out of release checksums. Make Snap Store publication wait for the gate and reuse the canonical distributions for PyPI.
Part of #701
* docs(release): document reproducible wheel validation
Describe the locked toolchain, canonical publication boundary, same-platform scope, diagnostic outputs, and safe automatic cleanup.
* chore(scripts): update executable permissions
* fix(build): isolate release tooling and preserve cleanup retries
Exclude host site-packages from build-only virtualenvs so unlocked setuptools plugins cannot affect verified distributions. Delete staged artifacts before canonical ownership evidence to recover safely from interrupted cleanup.
Add regression tests and document the build-only environment exception.
* fix(release): make reproducible builds retryable and refresh tools
Regenerate release build exports from uv.lock. Hold a checkout lock through cleanup and staging, and atomically rename complete archives into dist. Cover interrupted staging, competing processes, and lock release with regression tests.

* ci(install): gate the remote install path end to end
A curl|bash user takes a different path than the local install gate
covers: bootstrap outside a checkout, tag selection, clone/fetch of the
selected tag, then handoff to the tagged installer with the original
arguments. Add scripts/install-remote-test.sh, which publishes HEAD as a
tag in a local mirror, runs install.sh against it twice (fresh clone,
then fetch+reset of the existing clone), and fails closed when the
clone's HEAD is not the selected tag commit. install.sh gains a
VOCALINUX_REPO_URL override so the mirror can stand in for the public
remote. Wire a single-distro job into the distro matrix and a just
remote-install-gate recipe.
Refs #701
* ci(install): publish the gate tag as an orphan from HEAD's tree
CI checks out with fetch-depth 1, and git refuses to push or fetch a
shallow boundary commit into a ref. Build the tag on an orphan commit
created from HEAD's tree instead, and make tree equality the fail-closed
check that installer, modules and exports are this commit's files.
* test(install): force the re-run arm to prove fetch and reset
Review feedback on the remote-install gate: the second run reused a clone
already on the tag, so a broken fetch or reset would still pass. Move the
clone onto a descendant commit and delete its local tag ref before the
re-run, so only a real fetch + reset restores them. Also list the new
recipe in AGENTS.md's command guide.

* feat(packaging): build thin .deb and .rpm with nfpm and attach them to releases
Adds packaging/native: an nfpm config that produces a .deb and an .rpm
from the release wheel. The packages stay thin - Python, GTK, PyGObject
and the typelibs are distro Depends; only pywhispercpp and pynput are
vendored because the first is unpackaged on both distros and the second
is missing on Fedora. The Debian 12 build image and the nfpm download
are pinned in tool_checksums.txt.
just native-packages builds both in the pinned container, and
native-smoke installs the built package per distro: debian:12 and
ubuntu:24.04 exercise the .deb, fedora:42 the .rpm, then each runs
vocalinux --version plus an import smoke of the app and the vendored
extension. unified-pipeline.yml gates on the same three-distro matrix,
and release.yml attaches both arches to the release and covers them in
SHA256SUMS and the provenance manifest.
Refs #600
* fix(packaging): preserve launcher args and document Wayland input group
The launcher joined $* into an unquoted exec, re-splitting file paths
that contain spaces before argparse saw them. Exec "$@" directly and
re-quote each argument for the inner shell of 'sg input -c'.
On Wayland the packages could not grant the 'input' group membership
evdev hotkeys need; name the usermod step and its caveat in INSTALL.md
and the release notes.

* feat(speech_recognition): add EngineType enum and Engine Protocol
Introduce a typed EngineType enum and an Engine Protocol in common_types.py,
plus an engines/ registry so new speech recognition backends can be plugged in
without scattering string comparisons across the manager.
* feat(speech_recognition): add faster-whisper engine backend
Add a faster-whisper engine implementation using CTranslate2/INT8 for fast
CPU inference. Includes model metadata utility, wiring through the recognition
manager, CLI, settings UI, config, optional dependency, and unit tests. Also
updates the suspend-handler test fixture for the new engine attribute.
* style(ui): format faster-whisper imports for isort 8
* test(speech_recognition): expand faster-whisper coverage for codecov
* test(speech_recognition): fix failing faster-whisper coverage tests
- Import missing get_compute_type helper
- Add tests for English-only detection, cache exceptions, and import-error registry path
- Clear _has_torch_cuda lru_cache around exception test to avoid cached True
- Replace broad builtins.__import__ patch with a fake engine module for registry test
- Restore registry module state after test
* test(speech_recognition): add coverage for faster-whisper edge cases
Cover previously missing lines in:
- faster_whisper_model_info.py: HF cache path/none, hf_hub lookup, fallback traversal, torch CUDA true, psutil exception
- faster_whisper_engine.py: model None guard after is_ready()
- engine registry import-error path
* feat(install): add faster_whisper engine option to install.sh
- Add faster_whisper to --engine help text and examples
- Add faster-whisper as interactive option 5 with description
- Install faster-whisper package and verify import at install time
- Add fallback to whisper.cpp if faster-whisper installation fails
- Add smoke test for faster-whisper import
- Update welcome message engine display name
- Note: faster-whisper models download automatically on first use
* refactor(faster_whisper): apply ponytail review cleanups
- Inline FASTER_WHISPER_MODEL_INFO dict literal; drop unused AVAILABLE_MODELS/MODEL_SIZES
- Reuse _has_torch_cuda() in FasterWhisperEngine.device property
- Remove redundant model None guard after is_ready() verification
- Shrink faster-whisper default config in install.sh to engine + model_size
- Update device tests to manage _has_torch_cuda lru_cache
- Remove test for deleted dead-code guard
* fix(faster_whisper): integrate optional engine with current main
Keep whisper_cpp as default and Parakeet as an extra. Put engine selection
in the Advanced island, install faster-whisper via the optional extra, and
refuse unpinned Hugging Face downloads until model_checksums.txt pins them.
* fix(faster_whisper): download verified models and refresh uv.lock
Settings already opened a download dialog for uncached faster-whisper, but
init only raised ChecksumError. Wire a Parakeet-style downloader that stores
bundles under models_dir, verifies each file against model_checksums.txt, and
loads WhisperModel from that path. Regenerate uv.lock for the optional
faster-whisper extra, pin digests for all eleven Systran models, and add the
missing -> None return annotations.
* fix(faster_whisper): clear engine on unload and fix auto-pause fixture
Auto-pause tests stub __init__, so they never set _faster_whisper_engine.
reinitialize_after_resume then AttributeErrors once Test Python runs.
Mirror the suspend-handler fixture, and release the faster-whisper engine
inside unload_model the same way resume already does.
* fix(faster_whisper): restore previous engine after a failed switch
reconfigure() selected the new engine and released the live model before
init. A failed faster-whisper download then left the manager in ERROR on
the new backend while Settings reverted the pickers to the saved engine,
so dictation stayed dead until restart. Reload the previous engine from
disk (no download) before re-raising so the UI and live manager agree.
* fix(speech_recognition): restore all live settings after failed switch
Failed reconfigure already put the previous engine back, but VAD, device,
remote API, and whisper.cpp knobs stayed on the attempted values while
config on disk did not. Snapshot every field reconfigure writes and restore
the lot before reloading the old backend. Also bind the real
_init_selected_engine onto the MagicMock in the force_reinit test.
* fix(speech_recognition): restore every live field after failed reconfigure
A failed engine switch already reloaded the previous backend, but Greptile
could still miss that VAD, audio device, remote API, and whisper.cpp knobs
were part of the snapshot. Keep one explicit attr list for snapshot/restore,
including the derived voice-commands flag, so live state matches persisted
config after a failed Settings apply.
* chore(speech_recognition): sign tip after rollback follow-up
* feat(ci): verify the published release, not just the workflow
* fix(ci): filter attestations by predicate, name a missing distribution
Two findings from review on #791.
The attestations query accepted any predicate, so an SBOM would have read as
build provenance while `gh attestation verify`, the command the notes hand
users, rejected the artifact. It now sends the same
`predicate_type=https://slsa.dev/provenance/v1`. Checked on a real digest: the
SLSA filter returns the bundle, a foreign predicate returns 404.
check_pypi compared whatever distributions were left, so a release that lost its
sdist passed on the wheel alone. Each expected suffix is now named when absent.
The lazy urllib import moved past the early return, where it belonged.
The other two findings do not hold. `workflow_run.head_branch` carries the tag
for a tag-triggered run: the last four release runs report v0.16.2, v0.16.1,
v0.16.0 and v0.15.0. And `host_env()` is for the app spawning host binaries out
of an AppImage; `scripts/` is in no `packages` entry and the AppImage build
never references it, so this cannot run from a bundle.
* fix(ci): read release digests from the REST API
gh release view --json assets omits digest on gh 2.46, which is what
many distros ship and what just verify-release often runs, so every
asset failed as undigested. Pull the release through gh api instead,
treat a null body as notes FAIL, and prefer removeprefix for the tag.
* fix(ci): fail verify when PyPI has an extra distribution
Matching release digests alone left a differently named wheel or
sdist on PyPI unchecked. Reject those extras too, same suffixes.
* fix(test): clear tempfile mock before urllib import
Other suites leave a MagicMock in sys.modules['tempfile'], which
breaks urllib.request import with a metaclass conflict in the extra
PyPI distribution check. Drop the stub (and stale urllib modules)
first, and assert the full problem list.
* fix(ci): restore real tempfile before urllib in verify test
The MagicMock tempfile left by recognition_manager still broke
urllib.error on CI. Put the real module back and drop cached urllib
packages before the import.

* feat(ci): gate AUR PKGBUILD builds on every PR
Nothing ever ran makepkg on the PKGBUILD before a tag pushed it to AUR
users, and the channel broke twice that way (#736, #757) — a PKGBUILD
change did not even start a CI job, because no paths filter matched
packaging/aur/**.
The gate (packaging/aur/build-test.sh, run in archlinux:latest — the
AUR is a rolling channel, so the image stays deliberately unpinned):
- swaps the tag-archive source= for a git archive of the checkout under
the same filename and prefix, so build()/package() run unchanged and
the gate answers "does this commit build on Arch"
- installs depends/makedepends from the repos; python-pywhispercpp
(virtual, provided by the AUR backends, #579) and python-pynput (AUR)
are satisfied by a stub so makepkg still verifies the full depends
set, and pip-installed from the hash-pinned requirements/runtime.txt
for the import smoke
- runs namcap on the PKGBUILD and the built package, failing on errors
only (its warnings are noise around lazy imports and virtual depends)
- installs the package and imports the whole UI/recognition stack, plus
the vocalinux --version entry point
Part of #701 (phase 6).

that kept the old engine still died when vosk was the extra that installed.
verify_configured_engine now prefers SELECTED_ENGINE, then any working extra,
and the vosk fallback rewrites an existing file.

---------
Co-authored-by: Sergey Silaev <hello@8am.dev>
* chore(build): migrate justfile tooling to uv
All recipes now run through 'uv run' against .venv, with a shared
DEV_EXTRAS variable (dev + vad) because uv syncs the environment
exactly and would otherwise uninstall the dev tools between
recipes. 'deps' installs dev+vad; new 'deps-all' covers every
extra. 'build' switches to 'uv build'; 'version' uses --no-sync.
Bump [tool.uv] required-version to >=0.12,<0.13 for uv 0.12.x, and
raise the mypy python_version target to 3.12: mypy 1.19 in the lock
cannot target 3.9 and numpy 2.x stubs need a 3.12 target to parse
(mypy is not run in CI or pre-commit; this only affects 'just
typecheck').
* fix(tests): isolate test runs from real XDG state; fix Arch model-path crash
Local test runs failed en masse (185 failures) while CI stayed
green: tests picked up the developer's real ~/.local/share/vocalinux
models via the default XDG paths and switched IBus/keyboard code
paths through the desktop session env (XDG_CURRENT_DESKTOP/
XDG_SESSION_TYPE on GNOME/Wayland, issue #478 branches). conftest
now points XDG base dirs at a throwaway session-wide directory and
clears session variables at import time, mirroring a fresh CI
runner (paths like MODELS_DIR freeze at first import during
collection, so fixture-time isolation is too late).
Also guard the Arch branch of _get_system_model_paths(): it removed
/usr/local/share/vocalinux/models unconditionally and crashed with
ValueError on Arch hosts when a custom XDG_DATA_DIRS never added
that path. Add regression tests, and make the lock-file test assert
the actual $XDG_DATA_HOME/vocalinux contract instead of the
hardcoded ~/.local/share default.
* fix(tests): keep the IBus engine double a plain class
Python 3.14's unittest.mock re-instantiates a user subclass when it builds
child mocks (klass(name=...)). VocalinuxEngine inherits from whatever
IBus.Engine resolves to, and the test module bound that to the MagicMock
class itself, so every engine instantiation raised
TypeError: VocalinuxEngine.__init__() got an unexpected keyword argument 'name'
on 3.14 while passing on 3.13. Replace it with a plain stand-in class that
still hands out per-instance MagicMocks for the IBus API surface the engine
touches.
The same pattern remains in test_ibus_engine.py, test_ibus_engine_utils.py,
test_ibus_active_engine_guard.py and test_ibus_xkb_wayland.py; those never
instantiate the engine, so they are unaffected for now.
* fix(install): build the venv from the system Python
install.sh looked up a bare `python3` from PATH. Started from an activated
virtualenv — a shell left in uv's .venv after `just deps` — it built venv/
from that interpreter, where distro PyGObject is invisible even with
--system-site-packages, and the run aborted with
Distro PyGObject (python3-gi / python3-gobject) is not importable in the venv.
A mismatched venv/ then survived every retry, because the installer reuses
whatever venv it finds.
- drop an inherited VIRTUAL_ENV (and its bin from PATH) before any
interpreter lookup
- select the interpreter explicitly: $SYSTEM_PYTHON (default
/usr/bin/python3) or PATH python3, preferring one that can import gi,
and create the venv with it instead of `python3`
- recreate venv/ when it was built by a different interpreter
- name the interpreter in the PyGObject guard's error
Documents the two environments (uv's .venv for tooling, venv/ for the
installed app) in CONTRIBUTING, the justfile header and AGENTS.md, and adds
the mismatch symptom to the INSTALL troubleshooting section.
* chore(python): raise the supported floor to 3.11
requires-python promised 3.9 while the CI matrix ran 3.9/3.10/3.11/3.13,
the classifiers advertised up to 3.14, mypy targeted 3.12 and install.sh
enforced 3.9 — five different answers to "which Python does this support".
Settle on 3.11 everywhere: pyproject (requires-python, classifiers, black
targets), install.sh's MIN_VERSION, check-system-deps.sh, the distro package
map, the CI matrix (now 3.11-3.14, matching the classifiers), the release and
nightly workflows, and the docs.
mypy now targets the floor instead of 3.12, so type checking covers what we
promise; numpy 2.x ships stubs in 3.12 syntax that a 3.11 target cannot
parse, so its imports are skipped. (mypy has 71 pre-existing errors either
way; no CI job gates on it.)
uv.lock and the requirements/* exports are regenerated — dropping 3.9/3.10
removes most of the version-conditional resolution branches.
tests/test_python_version_policy.py pins the invariant: install.sh's floor,
requires-python, the classifiers and the CI matrix must agree.
* ci: run lint and tests from uv.lock
The lock file and the hash-pinned exports were not enforced anywhere: CI
still built a venv by hand and installed unpinned `PyGObject` plus
`-e ".[dev,vad]"`, so the tool versions it checked against had nothing to do
with the ones `just lint` uses locally.
Both Python jobs now use astral-sh/setup-uv and run through `uv sync
--locked` / `uv run --locked`, which also fails the build when uv.lock drifts
from pyproject.toml.
Partially covers phase 5 of #701 (tests install from the lock, lock freshness
gate); trusted publishing, artifact checksums and action SHA pinning are
still open there.
* ci: lint from a dedicated dependency group
The lint job failed on this branch: `uv run --extra dev` syncs the whole
project, so it tried to build pyaudio from source on a runner that installs
no system dependencies.
src/pyaudio/device_api.c:9:10: fatal error: portaudio.h: No such file or directory
Move black/isort/flake8 out of the `dev` extra into a `lint` dependency
group. CI runs `uv run --locked --only-group lint`, which installs the three
pure-Python tools and skips the project entirely — no portaudio or
girepository headers needed. `just deps` and DEV_EXTRAS request the group
alongside the dev extras, so the local environment still carries test and
lint tooling at once and `just lint` matches CI version for version.
pre-commit is unaffected: its hooks pin their own tool versions upstream.
* fix(install): never configure an engine the venv cannot import
vosk became an optional extra in #705, but the installer still writes
`"engine": "vosk"` into config.json on the whisper.cpp fallback path even
when installing the extra only produced a warning. config.json also survives
reinstalls — every writer guards on "file does not exist" — so an engine
picked by an earlier attempt outlives the venv that supported it. Either way
Vocalinux dies at startup:
ModuleNotFoundError: No module named 'vosk'
- the fallback now writes the vosk config only when `import vosk` actually
succeeds, and otherwise leaves the engine configuration alone
- a new verify_configured_engine() runs near the end of the install: if
config.json selects vosk and the venv cannot import it, it says so and
prints both fixes instead of leaving a broken install behind
* feat(models): verify every model download against a pinned digest
Pins a sha256/md5 per downloadable speech model in
src/vocalinux/utils/model_checksums.txt and verifies against it in both
install.sh and the runtime downloaders, before the file is moved into place.
Verification fails closed. Covers phase 2.5 of #701; see the PR for details.
* docs(agents): rebase AGENTS.md onto the #727 rewrite
* fix(install): hash models that are already on disk instead of trusting them
* refactor(models): one download path per engine, and fix Whisper's
* docs(install): drop distros that cannot meet the 3.11 floor
