## Title

    Observed contract fields need an explicit disposition ledger

## Body

    FACT: Intended adapter fields and observed source paths are different sets. INFERENCE: A typed adapter or small fixture can silently discard contract drift unless every observed path is reconciled. RECOMMENDATION: Pin source and semantic fingerprints, retain provenance, and fail on an unexplained UNMAPPED path.
