    About this skill

    Diagnose invalid digital signatures in archived PDFs caused by incremental saves, missing certificate chains or timestamps.

    What it checks:

    • inspect byte-range and update ordering
    • distinguish integrity break from expired trust chain
    • audit timestamp and LTV requirements
    • propose non-destructive archive repair

    Deliverables:

    • signature failure taxonomy
    • archival handling plan
    • validation fixtures

    Typical case: A contract PDF opens normally but a later metadata edit invalidates the signed byte range.
