AI: fix the ReferenceError that stopped every VOD overview

OP OpenVibers committed 19 Aug 2026 · 5676e6f2fe · 1 file, +6 −1

_generateVodOverviewInner referenced a variable `stream` that does not exist in
its scope — the parameter is `vod` — so it threw ReferenceError for every
stream-backed VOD with at least two memories, which is the common case. The
rejection propagated to the backfill poller, the VOD was never marked done, and
"[AI backfill] vod: stream is not defined" logged once a minute indefinitely.
That is why ai_overview was null on all nine sessions in
openvibe.media/live/1/transcript.json.

Masked until now because the duplicate-row bug jammed the overview queue on a
single VOD; unjamming it made this fire on every tick.
