Simple labels, source-backed caveats.

Sufficiency score

• 0: catalog or context record only.
• 1: single still, sketch, or summary with weak time/location context.
• 2: direct media or paired document exists, but key telemetry is missing.
• 3: enough date/location/media context for partial external correlation.
• 4: full-motion evidence plus timestamp, location, platform, and sensor context.

LLM boundary

LLMs can help draft plain-language summaries and organize metadata. They do not decide whether a clip shows anomalous performance. Conclusions are based on source records, deterministic measurements, visual review, and explicit missing-data limits.
