WeaveTrail’s AI That Keeps Its Receipts
A bilingual market-surveillance project where AI proposes interpretations, people approve them, and fixed code replays the evidence.
Field notes
WeaveTrail presents a four-stage review boundary: a constrained mapper proposes meanings for source columns but cannot calculate; a person approves the proposal before version-pinned code replays sorting, deduplication, calculations, and hashing. Its worked example uses KOSPI 200 data for 2026-09-03, with one-minute plotting and source-row traceability. The page labels the current environment fixture mode, using synthetic cases and permitted published prices; live proposals and evidence-bundle export are described as planned.
