Propose goal, incident and session clips from the live feed — each carrying the decision it turns on, its captions and the window it may run in, and a named producer publishes.
Take the live or just-finished feed with its timecode, the venue event log and the gallery's own flags beside it.
02
Read the clip window for that competition and territory, the caption stream and the do-not-clip list in force.
Reason
03
Mark candidate moments from the vision, the audio and the event log, and note what preceded each one.
04
Set in and out points around the whole passage, so a review, a reversal and the outcome stay inside the clip.
05
Carry caption text and the audio bed through the cut, and measure short-form loudness on the clip itself.
Decide
06
Hold what the do-not-clip list names: a serious injury, crowd disorder, a pitch invasion, a minor in shot.
07
Route a moment still under review, or a window closed in that territory, to the person who owns it.
Out
08
Hand the producer the clip with the passage it came from, the decision as it stood and the window it sits in.
09
Retain the feed timecode, the event log read, the holds raised, the producer's recut and where the clip ran.
→Product statement
The agent proposes clips and holds them. It publishes nothing itself, makes no synthetic commentary voice or altered likeness, and a named producer decides what goes out.
Example workflow
One clip, end to end
AgentHuman
1Feed runningThe match or session feed, its timecode, the venue event log and the caption stream
2Moment markedVision, audio and the event log agree something happened, and the passage around it is read
3Clip boundedIn and out points set around the whole passage, with captions and the audio bed carried through the cut
4Checks appliedDo-not-clip list, the status of the decision, the clip window for that territory, captions and short-form loudness
No human action required
Stages 1 to 4 run without a person in the loop — the feed is watched and the clip bounded before anyone is asked to look at it. A hold on the passage ends that stretch.

✓Mark candidate moments from the vision, the audio and the event log.
✓Bound the clip on the whole passage, not the moment alone.
✓Carry captions and the audio bed through the cut.
✓Raise every hold, closed window and unsettled decision it finds.
Write actions run only inside the approval boundaries agreed during implementation. Posting a clip is not one of them.
Signing off a clip across a reversed decision.

03Cutting
Keep the passage, not the moment
Bound the clip on what came before and what came after, so a review, a reversal and the outcome stay inside it.
01Approved path
Have the clip ready before the ask
Candidate cuts, their captions and the window they sit in are assembled while the event runs, so the producer reads a clip instead of building one.
02Human review
Say what the cut leaves out
A decision still being checked, a foul outside the frame, an answer clipped short of its qualifier or a hold on the passage is raised before anything goes out.
04Build an evidence trail
Retain the feed timecode, the passage bounds, the holds raised, the window read, the producer's recut and where the clip ran — on both paths.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and what goes out
Each control wraps the one inside it. A clip clears every layer before a producer can publish it, and a synthetic commentary voice sits outside all six.

How Nestack evaluates it
Evaluate the cut and what it left out.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Failure modes
Where each failure originates in the agent
Seven failure modes plotted against the five stages of the agent lifecycle. The ones that matter most are the ones a deletion cannot take back.

Sev-1 · the clip misrepresents or exposes someoneSev-2 · the clip breaches a window or ships brokenSev-3 · clips drift and more is recut
A decision still being checked, a stoppage that turns out to be an injury and an answer clipped short of its qualifier are where a producer recuts and where a clip is deleted after posting. Nestack reports performance by slice, not only in total.

Evidence-linked improvement
Speed is what makes the check get skipped
A clip that arrives late is worth less, and everyone in the chain knows it. The cycle has to make the check cheap enough that nobody has a reason to skip it.
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Recuts, deletions or corrections cluster on a competition or a feed.
02Diagnose
Traced to the event log, the passage bounds, the hold rule or the window record.
03Improve
The bound, the hold rule or the window record is corrected with your supervising editor, and version-linked.
04Verify
Re-run against held-out passages, including the clips that were deleted after posting.
05Learn
The deleted clip is kept as a worked passage, and the rule it broke is written into the gallery brief.
Learn → DetectThe return edge. Clip windows and competition terms are re-read each cycle — what could be cut live last season may not be this one.

Next step · Media AI agent
Build a clipping agent around your gallery and your live feed.
Show us a fixture you covered last month, the feed and event log behind it, and the clips you deleted afterwards. We'll re-cut that event against your own windows and holds, and show you what it stopped, what it got wrong and how late each clip would have been.
