Witness videos in, a fireball's path out.

How the agent works

Muse Spark watches each video: camera type, edits, on-screen clock, when the fireball shows, and landmarks a map could locate.
SAM 3.1 follows the fireball frame by frame from the phrase "bright light". The agent's track tool runs it on any clip nobody has tracked yet; with a plain brightness threshold instead, the same two cameras give a heading more than 20° off.
Each camera is oriented from lines and landmarks in one frame. That step is not automated yet: during development, AI annotators (Claude Code, not a Meta model) measured the lines and matched the landmarks to OpenStreetMap, and the code fits a camera model to them, so every pixel becomes a direction in the sky.
The agent, Muse Spark 1.3 calling tools in a loop, compares the cameras' planes of sight, solves, leaves cameras out, finalizes, writes the report or asks for missing evidence. Two planes from different sides cross in the trajectory; speed comes from each video's own frame times.
The code checks what matters: a camera leaves the solution only on a criterion the code measures; the chosen cameras are re-solved before they are accepted; a report is refused if a figure does not match a tool result of the same kind or if it states another verdict than the code's; and the run stops for a person, who signs the report off or supplies the evidence. The published answer sits where the agent cannot read it; a separate script grades the run.
