Final slice of the bug-tracking work.
- toastErrorWithReport adopted at the high-traffic failure sites: TTS
generation, dub upload/ingest/transcribe, engine install, engines-matrix
load, voice profile save/delete/test, batch enqueue/cancel/delete.
Validation toasts and cancellations stay plain on purpose.
- utils/breadcrumbs.js: local-only ring of the last 20 action names
(closed-set names only — never content or paths), embedded as a
'Recent actions' section in the prefilled report. Instrumented: view
changes, generate, dub pipeline, export, engine switch.
- deep self-check: /system/diagnose?deep=true and --diagnose --deep load
the active engine and synthesize a short utterance (num_step=4) —
catches 'installed but broken'. 180s time-box, skips during model load,
scrubbed failure detail. Verified live: cold-loaded omnivoice and
produced 2.2s of audio in 43.9s on CUDA.
- 'Search similar issues' action on the ErrorBoundary: scrubbed,
noise-stripped GitHub issue search URL — dedupe before filing.
- bug_report.md template now points at the diagnostic bundle and the
--diagnose CLI so manual reports arrive with the same evidence.
Tests: pytest 107 passed (4 new deep-check tests, CJK gate green);
vitest 218 passed (breadcrumbs + issue-search suites); vite build green.
