* feat(demos): ship the demo audio and video the app already advertises

Every demo asset in the app was a dead link on anything but a Mac.

`personalities.py` has carried a `preview_url` for each of the seven
voice-design presets since they were added; DictationDemo.jsx posts three
bundled WAVs to /transcribe so the feature can be shown without microphone
permission; the Dub workspace reads a manifest and plays a source video plus
four dubbed languages. None of those files were committed, because the tooling
that renders them (scripts/build_demos.sh, scripts/build_dub_demo.sh) hard-
requires macOS `say` — it even carries a `TODO: add espeak-ng path for Linux
contributors`. So the presets returned 404, the replay buttons did nothing, and
the dubbing demo never loaded.

Rendered with VoiceStudio's own engine, which runs wherever the app does:

- 7 voice-design previews (2.2 MB)
- 3 dictation replay clips (1.1 MB) — verified by transcribing them back:
  the conversational and French clips round-trip exactly
- dubbing demo: source + 4 dubbed videos with subtitles and manifest (9.6 MB)

Tooling fixes this turned up:

- build_dub_demo.sh wrote to backend/assets/demo/dubbing, but main.py mounts
  backend/assets/samples at /demo_audio — so the frontend's
  /demo_audio/demo/dubbing/manifest.json could never have resolved even after
  a successful Mac build. Output moved under the mount.
- `say` is now the fallback rather than the requirement: the new
  scripts/render_dub_demo_audio.py renders the five tracks with the engine and
  the shell script picks them up.
- The five demo paragraphs lived in two files. They are now one JSON both read
  — two copies is one edit away from a video whose subtitles disagree with it.
- render_demos_omnivoice.py peak-normalized, which a single-sample transient
  defeats: the Helpdesk preset landed at -30 dB RMS against -17 dB for its
  neighbours, so the preview row played at wildly different volumes. Now EBU
  R128 at -18 LUFS with a -1.5 dBTP ceiling.
- …and pinning the output rate, because loudnorm resamples to 192 kHz
  internally and writes there unless told otherwise, which turned 2.1 MB of
  previews into 17.5 MB of identical-sounding audio.
- update_manifest() looked for a manifest at a path nothing writes, so it
  always printed "not found" and did nothing.
- Dictation is rendered here now too. It was excluded on the grounds that
  `say` was good enough and engine TTS was overkill — true only on macOS.

tests/test_demo_assets_exist.py resolves every advertised URL against the
directory main.py actually mounts, and checks each dubbing subtitle matches the
script its manifest entry claims. A missing static file is not an import error
and not a failing request; nothing would have caught this otherwise.

* docs(changelog): stamp the demo-asset entries with their PR ref

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(demos): watermark rendered demo audio, and harden the render scripts

Review findings on #1517:

- Greptile P1: the renderers wrote engine output straight to disk, so a
  re-render shipped demo audio with no provenance mark. These clips play
  back to users as VoiceStudio output — they are synthetic audio leaving
  the app like any other, and now go through mark_synthetic (#1169), the
  one chokepoint every producing route uses. It runs on the file AFTER
  loudnorm, since loudnorm re-encodes what it is handed, and says so
  loudly when marking is unavailable rather than committing an unmarked
  asset. The dubbing renderer shares the same helper.
- CodeRabbit: build_dub_demo.sh checked only source.src.wav before
  deciding it could run without macOS `say`, so a Linux or Windows run
  with four of five tracks present reached a missing one, called `say`,
  and left a half-built bundle. It now requires all five.
- CodeRabbit: shutil.move over an existing path delegates to os.rename,
  which raises FileExistsError on Windows — os.replace overwrites
  atomically everywhere.
- CodeRabbit: the preview test discovered presets in a parametrize
  argument, importing app code at collection time and leaving
  core.personalities in sys.modules for later tests. Discovery moved into
  the test body.

CI: the rendered dub bundle's zh/ja subtitles, its manifest and the
script source are dubbing CONTENT, not UI strings — allowlisted in
test_no_hardcoded_cjk.py with that justification.

* fix(demos): a render that cannot be watermarked fails instead of warning

CodeRabbit and Greptile, #1517: mark_synthetic degrades rather than
raising — correct for generation, wrong for a render script, whose whole
job is to produce files a human then commits. A printed warning on a
scrolling console is not a gate, so both scripts exited 0 with unmarked
assets sitting on disk ready to commit. They now raise, with the reason
and the fix; OMNIVOICE_DEMO_ALLOW_UNMARKED=1 stays for a local listen.

* ci: stop a flaky dependency fetch from failing green runs

en-core-web-sm resolves to a direct GitHub release URL, and github.com
intermittently answers `http2 error: refused stream before processing
any application logic`. uv's own three retries all land within the same
few seconds and fail together, so the whole job dies on a dependency
that has nothing to do with the change under test — it cost #1518 and
#1517 an otherwise-green run tonight.

Two changes: back off between whole `uv sync` attempts, which is what
actually clears it, and pass --no-sync to the pytest steps. `uv run`
re-resolves the environment before running, so every test step was a
fresh chance to hit the same fetch even though the install step had
already synced — that is exactly how #1518 failed, in the isolated
backend/tests step, with all 5467 tests already passed.

* ci: one retry seam for every uv sync, not just the job that failed last

en-core-web-sm resolves to a direct GitHub *release* URL rather than a
package index, and github.com intermittently answers `http2 error:
refused stream before processing any application logic`. uv's own
retries all land inside the same ~10 seconds and fail together, so a job
dies on a dependency unrelated to the change under test. Tonight that
cost four otherwise-green runs across #1515, #1517 and #1518 — and the
first fix only covered the Tests job, so the next failure simply moved
to Smoke (Linux), which syncs separately.

The fetch is per-job, so the fix has to be per-job: scripts/uv-sync-retry.sh
backs off between whole attempts (15s, 45s, 90s) and every workflow that
syncs now goes through it — ci.yml (tests + the platform matrix),
release.yml, security.yml, evals.yml. It still fails loudly after four
attempts, so a genuinely broken lockfile is not disguised as a flake.

The Tests job also lacked the UV_HTTP_TIMEOUT / UV_HTTP_RETRIES the smoke
matrix has always set, which is part of why it was the one that kept
dying; it has them now.

* test(ci): pin the Intel-Mac contract by intent, not by command spelling

test_ci_verifies_intel_mac_as_the_documented_remote_only_host asserted
the literal line `run: uv sync --extra pockettts`, so routing every sync
through scripts/uv-sync-retry.sh read as a broken Intel-Mac contract. The
contract it exists to protect is that the pockettts extra installs ONLY
on backend_supported legs — which the regex now pins, while leaving how
the sync is invoked free to change.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* ci: keep every uv run out of the resolver, and bound the retry budget

CodeRabbit, #1517:

- `uv run` re-resolves before running, so the smoke suite, the
  worker-artifact tests, the release test run and the eval run were each
  a fresh chance to hit the flaky direct-URL fetch outside the retry
  loop. All of them pass --no-sync now; the environment is already
  synced by the step that owns the retries. security.yml's
  `uv run --with pip-audit` is deliberately left alone — it layers an
  ephemeral package rather than running the project's own tests.
- The retry count multiplied uv's own budget (UV_HTTP_RETRIES=5 with a
  120 s timeout on the smoke matrix). Three attempts and 60 s of total
  backoff outlast the refusals actually observed while staying well
  inside the jobs' timeout-minutes.
- The Intel-Mac contract test pinned the smoke command literally too, so
  --no-sync tripped it exactly like the sync line did. Same fix: assert
  the contract (smoke runs only on backend_supported legs), not its
  spelling.

debpalash 5832a81bb6 feat(onboarding): refresh the bundled demo voice 2026-08-11 19:02:38 +00:00
Palash Debnath 5cab8e0149 feat: rename the product to VoiceStudio (previously OmniVoice-Studio) 
Renames what users see. The app, the installers, the window title, the
docs and all 21 locales now say VoiceStudio, with "(previously
OmniVoice-Studio)" noted near the title of each doc surface so people
recognise it.

Deliberately NOT renamed, because renaming any of them silently breaks
an existing install — there is no legacy-path fallback anywhere in this
codebase:

  - bundle identifier com.debpalash.omnivoice-studio (MSI UpgradeCode,
    macOS TCC grants, managed venv, WebView localStorage, the
    single-instance lock)
  - data directories OmniVoice / .omnivoice and omnivoice.db
  - the ~150 OMNIVOICE_* environment variables
  - the X-OmniVoice-* HTTP headers (a wire protocol)
  - the published Docker image paths
  - the OmniVoice ENGINE, which is a model name and not this product

tests/test_identity_paths_survive_the_rename.py pins every one of those
so a future well-meaning sweep cannot orphan a user's library.

Linux .deb users install a new package name and should apt remove
omnivoice-studio; that note is in the changelog.

Palash DebnathandClaude Opus 4.8 8b00dc1f4f feat: onboarding demos, opt-in bug reporting, error-docs deeplinks + issue triage (#133) 
* feat: onboarding demos, opt-in bug reporting, error-docs deeplinks + issue triage

Working-tree snapshot bundling several in-flight workstreams (v0.3.0):

- Onboarding/demo system: DemoPresetGrid, DictationDemo, DubbingDemo components
  + tests, render scripts (render_demos_omnivoice.py, build_demos.sh,
  build_dub_demo.sh), personalities preview URLs, alembic 0002 voice-profile
  demo fields.
- Opt-in bug reporting: ReportBugButton (prefilled GitHub-issue URL path).
- Error transparency UX: errorDocsMap deeplinks + BootstrapSplash/error wiring.
- Dub workspace: DubSegmentRow/Table, WaveformTimeline, dubSlice tweaks.
- Issue triage: .planning/issue-clusters/ (plan-01..05 root-cause masters,
  GH #128-#132).
- CLAUDE.md: hard rule — everything ships on v0.3.0, no version bumps.

KNOWN GAP (why this is a draft): the generated demo audio assets are NOT in
this tree, and backend/assets/samples/demo_voice.wav is deleted. onboarding.py
guards the missing file (skips seeding the demo profile with a warning), so no
crash — but first-run Launchpad will be empty and /demo_audio/ preview URLs
404 until assets are regenerated via scripts/build_demos.sh. Do not merge
before regenerating + committing the demo assets.

* feat(dub): timing strategies — kill audio compression, add Concise + Stretch Video

Replaces the current audio time-compression default (atempo squeeze to fit
slot) that produced chipmunk/alien output on high-density target languages
like Bengali. Two new user-selectable modes; legacy behaviour kept behind
an explicit "Strict slot" choice.

New `DubRequest.timing_strategy` enum (default "concise"):
  - "concise"        Translator trims text to fit at natural rate; if it
                     still overflows, hard-trim at slot with a fade so we
                     never overlap the next speaker. Surface overflow_s
                     per segment so the user can shorten the text.
  - "stretch_video"  Audio plays at natural 1.0× rate. Backend computes a
                     per-segment new timeline; persists a video_stretch_plan
                     on the job. Mux step (dub_export) builds an ffmpeg
                     trim+setpts+concat filter graph that stretches each
                     segment's video portion to match the natural-rate dub
                     audio. Gaps/pre-roll/tail pass through at 1.0×.
                     Sub burn under stretch_video is skipped in one pass
                     (cues would drift).
  - "strict_slot"    Legacy atempo squeeze. Retained for back-compat.

Director rate-bias side-effect (seg_speed *= bias) now gated on strict_slot
only, so "urgent"/"slow" direction tokens keep their instruct effect in
the new modes without chipmunking.

Per-segment fit_status emitted in the SSE done event:
  {status: "fits" | "overflows" | "video_stretched", overflow_s?, stretch_ratio?}
DubSegmentRow's "Sync: 100%" badge (which was lying — sync_ratio was always
~1.0 because the TTS loop pre-trimmed to slot) is replaced with a truthful
"Fits / Overflows +Ns / Video 1.18×" label.

Frontend:
  - prefsSlice.timingStrategy (persisted, store v3→v4 with safe migrate).
  - DubTab footer Segmented control: "Concise · Stretch Video · Strict slot".
  - useDubWorkflow passes timing_strategy on /dub/generate; consumes fit_status.

Tests: tests/test_dub_timing_strategy.py — 13 cases covering schema
defaults/validation, _build_video_stretch_filter_graph (pre-roll, gap,
tail, empty-plan early return, post-subtitle chain-in), and
_video_stretch_plan_for guards. 30/30 existing dub tests still pass.

* fix(waveform): surface missing source as "Source media missing" instead of code-4 black box

When a project's underlying media file is gone (moved or deleted between
save and reload) the <video> element fires MediaError code 4 and the
companion audio fetch returns HTTP 404 — both were silently warned to
the console while the user stared at an unresponsive black panel and an
empty waveform.

- WaveformTimeline now flips loadError when the video element rejects
  code 3 (decode) or 4 (src not supported), and tracks `sourceMissing`
  separately so the error UI can name the actual problem.
- The audio decode fallback chain catches HTTP 404 specifically and
  treats it as source-missing instead of loading silent empty peaks —
  an empty waveform on a deleted source is more confusing than a clear
  "Re-upload the video to continue" message.

* fix(tray): "Show OmniVoice" reloads when the webview is blank

When the dev Vite server restarts (or the main window is created before
the backend is ready), the webview load fails and the window is left
with `<body></body>` plus a "Could not connect to the server" console
error. Clicking "Show OmniVoice" from the tray menu just re-showed the
broken window — there was no recovery path short of quit+relaunch.

Now the show handler runs a tiny eval after `show()`/`set_focus()` that
calls `location.reload()` only when `document.body.childElementCount === 0`.
A healthy window doesn't blink (body is non-empty); a blank one
self-recovers as soon as the user clicks Show.

* fix(#133): bug-report diagnostics field mapping + drop unused imports

Address PR #133 review:
- ReportBugButton: /system/info exposes `platform` + `device`, not
  `os`/`torch_device`/`gpu` — those reads silently dropped OS/GPU from every
  bug report. Map to the real fields (CodeRabbit). Also remove the dead
  `home` local in stripHome (CodeQL unused-variable).
- DictationDemo: drop unused `Loader` import (CodeQL unused-import).
