A shot with no COMP task rendered and previewed fine and then showed
nothing in the app. createExport set Export.taskId from the shot's first
COMP task or null, and finalizePreview registered the review Version with
that same null taskId — so the MP4 was uploaded and stored, but the
Version hung off no task and none of the review flows had anywhere to
draw it. From the artist's side the export completed and produced
nothing.
E1 now resolves the shot's comp task inside the version-allocation
transaction and creates one when there isn't any, titled after the
preview file the export will produce: {shotCode}_cmp_TT_{version}, the
same convention the manual batch upload's create-task path already uses.
renderOutputBase() is exported and buildPreviewManifest takes its `base`
from it, so the task title and the MOV/MP4 name come from one function
rather than two copies of the same template. The title therefore already
carries the version, which makes finalizePreview's rename-to-the-
delivered-version a no-op on that first export rather than an immediate
rename of a task created moments earlier.
The lookup and the create sit inside the transaction so the P2002
version-collision retry rolls a losing attempt's task back with
everything else, instead of leaving a duplicate behind.
recalcShotStatus runs only when a task was actually created: a shot with
no tasks derives WAITING and now has one. Approval-driven statuses still
take precedence, so an already-approved shot stays COMPLETE.
Both the queue-time ExportEvent note and the E1 response record what
happened, so a task appearing under a shot on its own is traceable to the
export that made it.
Exports already in flight with a null taskId keep their orphaned
versions; backfilling those is a separate migration.
