All translations now derive strictly from the approved English master VTT,
eliminating the cue-count and timestamp drift reported by linguists
(e.g. PL AD = 11 cues vs EN AD = 17 cues).
Key changes:
- Remove video_native translation mode entirely; all languages go through
translate_vtt() which guarantees 1:1 cue alignment with EN master
- Transcreation languages now use translate_vtt(style="transcreate") —
same cue-preserving contract, culturally-adapted instructions
- Post-translation cue alignment validator added (VTTEditor.assert_cue_alignment)
- After ingestion, job moves to PENDING_QC (EN-only) instead of TRANSLATING;
translation pipeline dispatches automatically when EN QC is approved
- New POST /jobs/{id}/retranslate-language endpoint for PM/admin to fix
legacy video_native jobs on demand
- Frontend: origin badge (EN-aligned / transcreated / video-native warning),
EN-first gate banner on target-language cards, Re-translate from EN button
with confirm modal, removed translation mode selector from NewJob

Heavy pipeline tasks (ingest, translate, render, rerender) now dispatch
to a Cloud Run Job (va-worker) instead of local Celery workers. optical-dev
runs only api + lightweight worker (notify/embed) within its 2-CPU budget.
- backend/app/tasks/runner.py — Cloud Run Job entrypoint
- backend/app/services/cloud_run_dispatch.py — replaces .delay() for heavy tasks
- backend/Dockerfile.cloudrun — Cloud Run worker image (ffmpeg included)
- docker-compose.optical-dev.yml — 2-CPU safe overrides, disables heavy workers
- cloudbuild.yaml — builds va-worker image and updates Cloud Run Job
- deploy-dev.sh — uses 3-file compose, builds only api+worker locally
- routes_jobs, routes_admin_production, ingest_and_ai, translate_and_synthesize
— all dispatch sites updated to use cloud_run_dispatch.dispatch()
USE_CELERY_FALLBACK=true in .env.local to use Celery locally during dev.
