  "note": "Vector 1 is a clean two-item sample frame, both items disposed with rationale, population and sample-frame population sizes reconciled: auto_pass. Vector 2 is the SAME two items but the sample frame's declared population size no longer reconciles to the lookback's declared population (500 vs 480) -- the art-470<->471 tie-out this node exists to close -- and holds ahead of grading coverage/rationale at all. Vector 3 declares a two-item frame but supplies only one disposition, evaluated as_of a date past the lookback's declared close date, exercising the escalate route. customer_id/alert_id are synthetic sha256-salted@1 commitment strings (repeated-hex-digit placeholders), never plaintext identifiers. golden_hash computed at fixture generation time via golden-parity.test.mjs --update.",
