Saatchi

Saatchi (சாட்சி, “witness”) checks what a worker says they did against what the video shows. Field work is often reported by voice note in Tamil or English, and nobody can verify it. Saatchi transcribes the narration with Muse Voice Transcribe, extracts checkable claims with Muse Spark 1.3, and checks each claim with two independent evidence channels: Spark video reasoning and SAM 3.1 object tracks. It marks each claim supported, contradicted or unverifiable. When the channels disagree or confidence is low it abstains instead of guessing, and asks for a short proof clip in Tamil and English. A scoring harness measures how often a false claim is wrongly confirmed, with confidence intervals. Built solo during the event with Claude Code assistance, as recorded in BUILD_LOG.md in the repo.
