chore(integration): land reviewed app, lifecycle and installer fixes - #1874
Merged
Conversation
An OpenAI-compatible ASR answering in json/text format returns no timestamps, and services/asr_backend.py records that honestly as `end: None` rather than inventing a number. The segment list called `.toFixed()` on it unconditionally, so the render threw and the whole Transcriptions view went blank — a transcript that merely lacked timings became one the user could not read at all. Show whichever bound is known and nothing when neither is, so the text stays readable either way. Non-finite values are treated as unknown too, so a bad timing prints nothing rather than NaN. Fixes #1798. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HR6J9zKQop9TGGVUwjypnF
…ms like A GPU with less VRAM than the engine declares it needs pages to system RAM over PCIe, so it renders slower than the same machine's CPU. The compute-time budget picked its value from the device family alone, so that card was treated as fast hardware and given 300s -- half the 600s a plain CPU host gets. It is the slowest configuration the app supports and it had the shortest watchdog. Everything else already acted on the verdict. resolve_routing() raises the caveat, the synth preflight warns before the user waits, and _timeout_guidance() names the card in the failure. Each TTS generate dispatch even hands the guard the engine's floor on the line above the timeout that ignored it. #1226 and #1222 were the same 4 GB cards on the same engine; both were closed by making the app explain the timeout better, never by correcting the budget behind it. generate_timeout_s() now floors an under-provisioned accelerator at the CPU budget. The length scaling is unchanged, and an explicitly configured OMNIVOICE_GENERATE_TIMEOUT_S is still honoured verbatim, so an operator who lowered the watchdog to fail fast keeps that. The floor is a max(), never an assignment, so a raised accelerated budget is never cut down. Engines that declare no floor, a failed VRAM probe, and MPS (whose vram_gb is a unified- memory heuristic, not a dedicated pool) are all untouched. The three-clause "is this host under-provisioned" test was written out inline in the caveat and in the timeout message, which is how the budget came to disagree with the warning printed beside it; it is now one predicate, under_provisioned_vram(), that all three read. Reported on a GTX 1650 (4 GB) running the omnivoice engine, whose breadcrumbs show the budget ending the job on the dot: 372s and 301s are exactly 300 + max(0, len - 1200) / 40 for the two takes. Fixes #1804.
…vert Review findings on the PR, fixed here rather than left for a fourth report. Greptile (P1): the control plane sets a remote attempt's deadline, so the same inversion reached remote workers. Its suggested fix -- thread the engine floor into generate_timeout_s() -- would read the wrong machine: that function probes THIS host, so a Mac control plane dispatching to a 4 GB Windows worker learns nothing (MPS is excluded by design), and a 4 GB box dispatching to a 24 GB worker would wrongly get the longer budget. The worker already advertises both figures it takes -- free_memory_bytes and min_memory_bytes, both set in worker/capabilities.py -- so ConnectedWorker.under_provisioned() decides from those, and deadlines.for_task() floors the execution budget at what the same job would get on a CPU. The task-level ceiling in gpu_gateway._default_deadline is computed before a worker is bound and already asks for the CPU budget, so it still covers the raised lease; a test pins that. CodeRabbit (major): /convert had the identical split -- min_vram_gb to the guard so a timeout could name the card, and a budget computed without it. CodeRabbit (minor): the docs promised the CPU-class floor for any GPU, while the code scopes it to dedicated-VRAM families. Reworded to say CUDA/ROCm and to say why MPS is excluded. CodeRabbit (minor): the call-site assertion compared global occurrence counts, so one dispatch could drop both arguments while another gained an extra and the total still matched. It now walks the AST and checks each dispatch on its own, and the pairing is additionally enforced repo-wide across backend/api/routers: a dispatch that knows the engine's floor well enough to explain a timeout must know it well enough to set the budget. Three inline capability-selection loops in ConnectedWorker collapse into one _capability_for(), so the new predicate cannot select a different capability than execution_device() does.
…dence Second review round on the PR. CodeRabbit: the repo-wide dispatch assertion accepted any nested min_vram_gb keyword, so a budget computed with 0 or another engine's floor would pass while the guard used the right one. It now compares the two expressions. CodeRabbit: the awaiting-side deadline test restated gpu_gateway's formula instead of calling it, so it would not have noticed that function starting to select a shorter ceiling. It calls _default_deadline now, on cuda and rocm. CodeRabbit: the docs said an explicit OMNIVOICE_GENERATE_TIMEOUT_S is honoured "everywhere" while also saying the CPU var governs under-provisioned cards -- the two cannot both be true. Verified against the code (both vars set, 4 GB cuda, engine floor 6 GB -> 200s, the accelerated value) and documented as a precedence table rather than prose. The accelerated var deliberately wins on an under-provisioned host: that is what keeps "lower it to fail fast everywhere" working. Pinned by a test so the table cannot drift from the behaviour. CodeRabbit also flagged that Scheduler._budget_for recomputes with no worker after a disconnect, dropping under_provisioned to False. That cannot shorten anything: no worker means no execution_device, which _base_execution_seconds already coerces to "cpu" -- the same budget the floor raises an under-provisioned card to. Added a test pinning that rather than persisting a dispatch-time budget on the attempt. The residual case it describes -- an operator who raised the accelerated budget ABOVE the CPU one sees a shorter recomputation once the worker is gone -- predates this change and applies to every GPU worker, not just under-provisioned ones, so it belongs in its own fix.
…loading Third review round on the PR, both findings in the new test file. CodeRabbit: the disconnect regression called deadlines.for_task directly, so it would have passed even if Scheduler._budget_for stopped coercing a missing worker to the CPU budget -- the very thing it exists to pin. It now builds a real WorkerPool and Scheduler, assigns the task to the 4 GB worker, asserts the bound budget is the CPU one, disconnects the worker and asserts the recomputation is not shorter. Forcing under_provisioned=False in _budget_for fails it with `assert 300 == 600`. CodeRabbit: the two env-var tests deleted the variables and reloaded model_manager inside a finally, which runs BEFORE pytest restores them -- so on a machine that already exports either var, the module constants would describe an environment pytest was about to put back, and every later test would read the mismatch. Both use monkeypatch.context() now, so the environment is restored before the reload.
A stray sqlite session artifact named `:memory:.ses` was committed by accident on this branch. Git on Windows rejects a path containing `:` with `error: invalid path` and exits 128 during **checkout** — so both Windows jobs went red before a single build or test step ran, pointing at a file nobody had edited, while Linux and macOS stayed green. Drop the file, ignore the `*.ses` artifact class, and add a guard that scans the index on every platform for paths Windows cannot represent: illegal characters, components ending in a space or dot, and reserved DOS device names. The failure now surfaces as a named test on every runner instead of as a checkout crash on one leg of the matrix.

The launcher waited a flat five minutes from spawn for the backend to report ready, then killed it and tried again. On a host where the cold start genuinely takes longer — the reporter's project lived on a mapped network drive, and `import torch` off one is slow the first time, as is a first CUDA load or a cold spinning disk — that deadline expired *while the backend was still importing*. The respawn threw away the warm page cache and raced the same clock, so the app could never start, and it blamed the backend: "the backend never reported ready". Launching that same backend by hand reached ready in well under a minute once the cache was warm. A backend answering `/startup/progress` with `status: "starting"` is not one we have to guess about: it bound its socket, it is serving HTTP, and it is naming the step it is on. Killing it cannot make the retry faster, and the launcher knows nothing the user doesn't. So keep waiting while it answers, and keep narrating each step. The budget still governs silence — nothing answering, or a self-reported `failed` — where a slow backend and a wedged one really are indistinguishable and the existing stderr-tail failure is the right answer. The splash needed the same correction. Its stall watchdog keys on `bootstrap_status`, which sits on `starting_backend` for the whole of a slow start, so it would have called the launch stuck at six minutes anyway; the proof of life arrives on the separate `bootstrap-log` stream. Output now counts as activity, and a genuinely silent backend still trips the watchdog so the info-less spinner of #879 stays fixed. Fixes #1791.

… did Two Apple Silicon reporters were told "it most likely crashed or was killed mid-request" while generating. Neither bug report carried a crash marker, because none had been recorded — the app had no evidence for the one thing it asserted, and the advice that follows that sentence is Retry and Clean & Retry, which rebuilds the whole Python environment to fix a backend that had not died. Two causes, both fixed here. The desktop shell learns the backend died from a ~2 s poll: it has to notice the child exit before it can write the marker. `apiFetch` asked for that marker exactly once, at the instant the transport gave up, so it raced the poll and lost either way round — a backend that really died was reported with the vague sentence instead of its exit code and crash notice, and one that never died was reported as dead anyway. `streamDropError` already waits that poll out (#1119); the request path never did. The loop is now a shared `awaitBackendCrashMarker`, used by both, with a shorter budget here because the transport cascade has already cost the user a few seconds. And the copy itself overshot what it could know. By construction it is reached only once a crash has been looked for and not found, so it no longer names one: it says the backend stopped answering with no crash recorded, and that a heavy job holding the engine is the likelier story — which on a memory-pressured Mac mid-generation it is. Updated in all 21 locales, since a translation still asserting a crash would be the same bug in another language. The #1337 test that required the crash wording is updated with it: #1337 established that the backend had answered seconds earlier, not what silenced it, and requiring the stronger claim is what pinned this in place. Fixes #1802. Fixes #1805. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HR6J9zKQop9TGGVUwjypnF
CodeRabbit's catch on #1799: git stores paths with `/` separators, so a `\` that survives into a path component is part of a NAME. It is legal to commit one from Linux or macOS and impossible to check out on Windows, where git refuses it under `core.protectNTFS` — the same checkout-time failure, before any test runs, that the stray `:memory:.ses` caused. The rule moves into a pure `windows_hostile_reason` so it can be exercised directly: the repo cannot carry a fixture for each hostile shape without becoming the very thing the test rejects. Both directions are pinned — every shape Windows refuses, and ordinary paths that merely resemble one (a file called `console.md`, `com10.py`, a component containing but not ending in a dot).

`_get_clone_prompt` catches everything and returns None so synthesis falls back to `generate()`'s inline reference path. For a device OOM that is not a fallback at all: the inline path runs the SAME encode on the SAME device — producing identical output is the entire point of the precompute — so it is guaranteed to hit the same wall moments later, on a GPU with even less headroom than the first attempt found. Two reporters' backends died with a Windows access violation (exit code -1073741819) seconds after this fallback logged, mid-generation, on a card that had just refused an 86 MiB allocation. An OOM here is also the most recoverable kind. The allocator is typically sitting on reserved-but-unallocated blocks — #1790's own log reports 90 MiB reserved against that 86 MiB request — so drop them and try once more. If it still will not fit, raise: the failure layer turns a device OOM into "close other GPU-heavy apps or unload models, then retry", which is a far better answer than walking into a native fault. Every other failure still falls back silently, since for a non-memory fault the inline path may genuinely succeed. Fixes #1790.

Greptile's P1 on #1809, and it is right. `launch_backend_and_wait` holds `BackendState::lifecycle` around the entire launch, including the readiness wait — which this branch just made unbounded for as long as the backend answers `/startup/progress`. Retry, Clean & Retry, reset and uninstall all need that same lock, so on a slow start the user's own escape hatch would block behind the wait instead of interrupting it: an app with no way out, which is worse than the early kill the branch set out to remove. Every flow that is about to take lifecycle ownership now bumps a generation counter first, before reaching for the lock. The waiting loop snapshots that counter once its caller holds ownership — so a bump that predates it is not mistaken for a preemption — and stands down within one 500 ms poll when it changes, releasing the lock for whoever asked. That also settles what happens at the splash's six-minute stall budget: it flips to failed and offers Retry and the logs, and Retry now actually works, while its /health recovery poll still walks straight into the app if the slow start finishes first. Either way the user gets out. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HR6J9zKQop9TGGVUwjypnF
Most gallery previews fail with "the voice engine returned no audible
audio for this archetype". The renders are fine — the guard is not.
Two problems, both in the degenerate-buzz check:
1. `_spectral_flatness` took ONE FFT of the whole clip. Spectral
flatness is defined over short frames; a full-length transform gets
finer frequency resolution the longer the clip is, so voiced
harmonics carve deeper and deeper nulls and the geometric mean
collapses. The number tracked clip length, not timbre.
2. `_DEGENERATE_FLATNESS = 0.015` was calibrated against
`_speech_like()` in the unit test — a synthetic harmonics+noise
stand-in that is far flatter than real speech. Real renders measure
well below it, so the threshold sat inside the speech range.
Measured on this engine's own output (framed, per this patch):
pure tone 80 Hz 2.6e-10 two-tone buzz 3.3e-09
quietest real speech 2.0e-04 (VoxCPM2 ko)
Frame the measurement (1024/512, skipping inter-word frames at the
noise floor) and move the threshold to 1e-5 — ~3000x above the tonal
cases, ~20x below the quietest real render.
Before: 6 of 8 renders rejected; ml_japanese_explainer,
ml_japanese_companion and feat_23_the_explainer all 503 through
GET /archetypes/{id}/preview.
After: 0 false positives across 27 real clips (Japanese, Korean and
English archetypes, cloned voices, human reference recordings), and
those three previews return 200. Every accepted clip was confirmed as
real speech by transcribing it with the app's own ASR.
Not addressed: a render that collapses toward NOISE rather than a tone
still passes (one observed at flatness 0.073, ASR returns a
hallucination). The old threshold missed it too, so this is not a
regression — calibrating an upper bound needs more than one sample.
Tests: frame-based measurement must be clip-length invariant, and the
threshold must sit between the measured tonal ceiling and the measured
real-speech floor. Both fail against the previous implementation.

`bun run desktop` dies before the window opens on a fresh clone:
Error: ENOENT: no such file or directory, open
'.../frontend/node_modules/@tauri-apps/plugin-dialog/dist-js/index.js'
The alias hardcoded `frontend/node_modules/...`, but this is a bun
workspace: bun hoists the package to the workspace root and leaves
`frontend/node_modules` empty, so the path the alias names does not
exist. Vite's dep optimizer reads it directly and throws, taking
`beforeDevCommand` — and the whole desktop shell — down with it.
Probe both layouts and fall through to Vite's own resolution when
neither is present, so a missing package degrades to normal resolution
instead of crashing the dev server.
Verified on macOS 26.6 (Apple Silicon), bun 1.2.22, fresh clone: the
window now opens and the backend serves.

"20~30초" is read aloud as a single number — OmniVoice says "이십삼" (23).
The separator never reaches the listener, so any written range is heard as
the wrong figure.
`normalize_text` only ran its number pass behind `_num2words_lang`, which
returns None for ko/ja/zh/th/vi (those scripts read digits natively and are
deliberately outside num2words). Nothing else looked at the range mark, so
the tilde went to the engine untouched and the two numbers ran together.
Rewrite `N~M` into the spoken form before the engine sees it, outside the
num2words gate so the CJK languages are covered too. Verified by rendering
each candidate and transcribing it back (ko, OmniVoice, cloned voice):
"대략 20~30초짜리" heard "23초" WRONG
"대략 20-30초짜리" heard "23초" WRONG (reproduces it)
"대략 20에서 30초짜리" heard "20에서 30초짜리" correct
"20〜30分ぐらい" → "20から30分" heard "20〜30分くらい" correct
Deliberately narrow:
* Only the tilde family (U+007E, U+301C, U+FF5E). Japanese and Korean IMEs
emit the latter two. An ASCII hyphen is left alone — between digits it
also spells dates, phone numbers and product codes, where "to" is wrong
(`tests` already pin "pages 3-5" as unchanged).
* Only languages with a verified spoken form (ko/ja/zh/en). Anything else
keeps its tilde, matching how `_PERCENT_WORD` is scoped.
* Spacing belongs to the form, not the caller: a Korean postposition binds
to its numeral ("20에서 30"), Japanese and Chinese set no spaces, English
needs them on both sides.
* Neighbour guards block digits and ASCII letters but allow CJK, because
CJK writes the unit hard against the digits ("20~30초"); a `\w` guard
rejects exactly the cases the rule exists for.
`ko`/`ja`/`zh` join `_FULL_NAME_TO_CODE` so the new resolver can see them.
They stay out of `_NUM2WORDS_LANGS`, so this does not open a num2words path
for them — the same inert-entry pattern the file already documents for
"vietnamese".
`backend/services/text_normalization.py` joins the functional-CJK allowlist
in tests/test_no_hardcoded_cjk.py, under the text-processing group and by
the procedure that file documents: the range words are engine input, not
user-facing UI strings.
Tests: 7 new change-cases and 8 new leave-unchanged cases (hyphen, date,
phone number, product code, decimals, a non-numeric tilde, an unverified
language, and no language at all). All 7 change-cases fail against the
previous implementation.
Full suites before and after: the same 17 failures, none of them touched by
this change.

Cover every newly added locale key in the parity test.
_REQUIRED_IN_EVERY_LOCALE covers only nine additions, while this change also adds keys such as settings.device_family_npu, clone.paste, and the waveform labels. Because _MISSING_BASELINE is aggregate, one missing translation can be masked by another improvement in the same locale; add every new key to named assertions or generate the required-key list from the locale diff.

The open PR queue contains overlapping frontend, lifecycle, inference, and installer changes that need validation together. This integration preserves the reviewed contributor branches and resolves their conflicts so the combined application is tested before landing.
Includes #1799, #1806, #1809, #1810, #1811, #1815, #1818, #1819, #1821, #1830, #1831, #1841, #1852, #1861, #1862, #1863, #1865, #1870, plus validation fixes #1871, #1872, and #1873. Findings were fixed on the original PR branches before integration. #1801 and #1803 are absorbed by #1799; #1823 is superseded by #1841.
Conflict resolutions preserve both log-state regressions, all visual fixtures, native macOS controls and their inset, contributor changelog entries, and both Windows release fixes. The macOS shutdown fix rechecks the owned, unreaped root after a denied process-group signal while preserving descendant draining and genuine permission errors. Merge with a merge commit to retain the original PR ancestry.
Validation:
The full combined CI must pass before merge; main post-merge CI must then pass. Canonical PR bot findings and the integration-specific conflict resolutions were reviewed independently. Greptile skipped the combined diff because it exceeds its file limit; that skip is not an approval. Physical XPU/NPU inference remains unverified. #1857 remains open because this includes OS reduced-motion support, not its requested application-level override. The preexisting sidecar compute-preference propagation limitation remains a release follow-up.
Integrates frontend, backend lifecycle and inference, accelerator routing, installer, release, validation, and UI changes, including target-scoped release retries and persisted worker deadlines. These changes improve startup recovery, timeout handling, dubbing workflows, accessibility, localization, and Windows MSI diagnostics. Human review remains necessary because physical XPU/NPU inference and Windows installation are unverified, and a sidecar compute-preference limitation remains open.
