Four Evidence records in teal: ev_3c6350b2 with 13 procedures, ev_ad37f574 with 39 strings from F to A, ev_41e8ca1c with 15 instructions and no caller, and ev_b201cfd0 naming _labels and DAT_1000007e8. One amber ledger with one row per claim: observed 5, derived 2, inferred 1, unknown 1, refused 1. The answer in grey stays unknown until read_bytes runs at 0x1000007d0 and 0x1000007e8.',
