House Rules

RULE I

No price without a source. Every figure traces to a dated record. Items we can't verify say “tracking not current” — never a guess.

RULE II

Sales outrank asks. A listing is an opinion; a close is a fact. Contradictory prints are discarded, not headlined.

RULE III

No invented history. New coverage opens with today's verified print and earns its ledger one night at a time.

RULE IV

The record is signed. Every note carries its serial, its audit stamp, and the date of its last refresh.
