A slate or burn-in mistake is usually caught after a preview has already
succeeded, and there was no way back: retryPreview required PREVIEW_FAILED, and
READY_FOR_QC only led on to QC_FAILED/READY_FOR_DELIVERY/SUPERSEDED. The only
recourse was a whole new export, re-rendering every EXR and burning a version
number to fix a typo.
- transitions: READY_FOR_QC and QC_FAILED can now go back to GENERATING_PREVIEW.
- regeneratePreview() rebuilds the manifest from scratch rather than patching
anything, so shot code, episode/scene, frame count, slate date and burn-ins
are all re-derived exactly as on a first-time preview. Validated EXRs are
reused and the version number is untouched -- this re-delivers the same
version, it does not make a new one.
- vfxScope and submissionNote are frozen onto the Export at submission time, so
regenerating refreshes that snapshot from the shot's slate fields (explicit
override wins, same precedence as createExport). Slate text edited on the web
app's Slate tab is therefore picked up.
- finalizePreview replaces the media on the export's existing Version instead of
stacking a second row, so the version number stays put and reviewer notes and
annotations survive the reslate. First-time previews are unaffected.
- POST /api/ext/exports/{id}/regenerate-preview exposes it to the panel.
- Panel: Regenerate Previews button, gated on the same statuses as the server,
with a confirm covering what is and is not reused.
Also fixes the slate description source: the Slate tab authors
shot.slateDescription (falling back to shot.description) but the preview
manifest only ever read shot.description, so edits made there never reached the
rendered slate.

finalizePreview now retitles the export's task so its version suffix matches the
preview that was just uploaded (UNG_102_019_010_cmp_TT_v004 -> _v005), which is
the rename the manual batch upload already does on rename-and-upload. The new
nextTaskTitle helper mirrors nextExrOutputBase so the task title, EXR base and
preview filename all derive the suffix the same way. It uses the export's
versionString rather than versionNumber, since the DB number is bumped to stay
monotonic per task while the filename follows the shot's shotVersion.
The rename only fires when a Version was actually created, runs in the same
transaction, and is recorded in the ExportEvent note; the finalize response now
returns the task id, title and whether it changed. Task status is deliberately
untouched (pipeline renders must not resurface in the review flow, S10.0).
The headless preview build was addressing the slate's identity fields by index
only, so ShotName was never filled on the farm. setSlateIdentity writes both the
named property and the index -- the name-with-index-fallback pattern the panel
already uses for VersionName -- and warns with the template's actual property
names when neither resolves, instead of failing silently.

One "Queue Export" click now renders the EXR sequence, then rebuilds the shot
headlessly with the studio slate/overlay template to produce the delivery MOV
and review MP4. Implements RenderPipeline2 phases 1-2 plus the preview stage.
Server:
- New models Export, RenderJob, ExportEvent, Machine, WorkerHeartbeat, plus
Project.deliveryConfig and per-submission slate fields (Export.vfxScope,
Export.submissionNote, inherited from the shot's previous export).
Both migrations are purely additive; no existing column is touched.
- lib/render-pipeline: server-enforced state machine, transactional version
increment with supersede, atomic FOR UPDATE SKIP LOCKED claim gated by
machine availability windows, and a lease reaper run from instrumentation.ts.
- /api/ext/* endpoints for the panel and workers; session-auth mirrors under
/api/render and /api/machines for the web UI.
- Pipeline pages: render queue, export detail, machine monitoring, plus an
Exports tab on shot detail.
RenderWorker (.NET 8 Windows service, new):
- Registration, heartbeat as cancel channel, claim loop, aerender runner with
progress parsing and stall watchdog, crash recovery and disk-spooled
reporting that survives server downtime.
- Preview stage: headless AE assembles the preview comp into a throwaway AEP
with both output modules queued, then a single aerender pass renders them.
Preview jobs are not claimed while an interactive AE session is open, so an
artist's project is never taken over.
AE panel: Queue Export with live status polling, urgent flag, retry, and the
VFX Scope / Submission Note fields. Every existing panel action is unchanged.
Preview chaining ships disabled behind SystemConfig preview.enabled.
