- Ignore backend model lifecycle webhooks so model warmup does not
mark jobs done early
- Parse batched SSE messages and relay model load states during
submit retries

Remove residual one-word suffix-prefix carry-over between adjacent caption segments so reprocessed transcripts no longer repeat bridge words across lines.

Collapse one-word and very short caption carry-over fragments so reprocessed YouTube transcripts do not retain residual prefix chains.

Normalize incremental backend hypothesis chains before persistence and ignore stale or replayed webhook callbacks so duplicate transcript text does not survive ingest.

Adds a beforeEach hook that clears subscriptions and resets mocks before
each test, making the suite robust against any state left by a previous
test even if afterEach didn't run cleanly.

Two bugs triggered together when the model was unloaded during a job:
1. submitJob() created FormData/createReadStream once outside the retry loop.
After a 503, the audio ReadStream was consumed and subsequent retries sent
an empty body to whisper, causing it to return segments:undefined.
2. webhook handler cast whisperJob.segments as Segment[] without guarding
against undefined, so deduplicateSegments(undefined) crashed with
'Cannot read properties of undefined (reading 'map')' — stored as job.error.
Fixes:
- Move FormData + createReadStream inside the retry loop (fresh stream per attempt)
- Use (whisperJob.segments ?? []) in webhook handler
- Add Array.isArray guard at top of deduplicateSegments() as belt-and-suspenders
Tests:
- New: verifies createReadStream called once per attempt (3 attempts = 3 streams)
- New: webhook handles segments:undefined without throwing
- New: webhook handles segments:null without throwing
- 150/150 passing

- Add cancelJob() to whisper.ts: sends DELETE /jobs/:id to the whisper
server (best-effort, errors silently ignored)
- DELETE /api/jobs/[id] now calls cancelJob() when cancelling an active
job that has a whisperJobId, stopping GPU use immediately
- Webhook handler guards against locally-cancelled jobs: returns ok early
so whisper's late completion cannot overwrite cancelled status or send
a phantom 'Transcript ready' notification
- Replace blind sleep(Retry-After + 1s) in submitJob() with
waitForModelReady(): subscribes to /model/events SSE and proceeds as
soon as state:ready arrives; falls back to the Retry-After timeout if
SSE is unreachable or closes without model_ready
- Refactor retry tests to use URL-aware makeJobFetch() helper; add 7 new
tests (3 SSE-triggered retry, 3 cancelJob, 1 webhook cancelled-guard)
— 144/144 passing

submitJob — 503 retry behavior (10 new tests):
- calls onModelWaiting with correct state + retryAfterSecs on each 503
- retries until model ready and returns job_id
- tracks all three model states (unloaded, loading, waiting_for_gpu)
- uses retry_after_secs from response body
- falls back to Retry-After header when body field absent
- falls back to 15s when both body and header are absent
- throws after maxAttempts exhausted (fetch called exactly N times)
- does NOT call onModelWaiting for non-503 errors
- does NOT retry on non-503 errors (throws immediately, one fetch call)
- works correctly without an onModelWaiting callback
getModelStatus (6 new tests):
- returns parsed status for each model state tag
- includes optional fields (loaded_at, vram_*, retry_in_secs)
- calls the correct WHISPER_URL/model/status endpoint
- throws when server returns non-ok
Uses vi.useFakeTimers()/runAllTimersAsync() to eliminate real delays.
Rejection handler attached before timer advance to avoid unhandled-rejection
false positives from Vitest's detector.

- whisper.ts: add getModelStatus(); fix submitJob() to retry on 503 using
Retry-After header instead of throwing; optional onModelWaiting callback
lets the pipeline surface model state to the UI during the wait
- pipeline.ts: pass onModelWaiting callback → emits model_warming SSE event
so the job detail page can show 'Warming up model…' while waiting
- types.ts: add ModelStateTag union and ModelStatus interface
- api/model/status: GET route proxies whisper /model/status (falls back to
{state:'unloaded'} if whisper unreachable)
- api/model/events: GET route relays whisper SSE stream to the browser;
AbortController tied to request.signal cleans up on disconnect
- layout.svelte: status pill is now live — initial fetch + EventSource on
/api/model/events; dot colour + label reflect real model state with a
pulsing animation while loading or waiting_for_gpu
- jobs/[id]/+page.svelte: handle model_warming event type → show a yellow
'Warming up model…' sub-label with spinner inside the progress card
- whisper.test.ts: update submitJob mocks to status:202 to match real API
