The store's hand-built claim interpolated the lane predicate into the SQL
text while still passing a bind parameter — node-postgres sent 1 param for
a 0-param statement (08P01) on every poll, so the live produce worker
store-errored every ~2s and never claimed. Migration 040 replaces the
inline claim with produce_job_claim(p_lane, p_stale_after): SECURITY
DEFINER (the 035/oidc_refresh_lookup pattern — the poller is lane-global,
FORCE RLS hides every row without a tenant context), atomic FOR UPDATE
SKIP LOCKED with the queued→transcoding bump as the lease, and stale-
transcoding reclaim so a killed worker's rows return to the queue.
produce_job_workspace(p_job_id) discovers the owning tenant for the
follow-up writes, which stay RLS-bound as sp_app. pg-store rewired; store
errors now surface err.message instead of err.name; pg-store tests added.
38/38 producer tests green.
Deployment (t4g2): media-worker gains font-dejavu (drawtext lower-thirds)
and a dedicated produce-worker compose service running src/produce.ts —
claims video_processing_jobs compose|mix by lane, renders assembled/
overlaid/voiced cuts, registers derived library assets. Deliberately its
own process so a remote-lane box needs only Postgres + S3 + ffmpeg.
Web: compose media attachments UI (t2), Producer panel in the video
drawer (t5), collective creation + branding settings + shell branding
(brandweb), mobile CSS (mcss: touch targets, icon sizing, safe areas).
