Filter combos, explained back to you

1 · Learn the move · Recipe pattern

Filter combinations get passed around like recipes - absentee, vacant, delinquent two years, five to forty acres, held ten years - and pulled without anyone saying what each filter keeps, what it quietly throws away, or why that order. The recipe pattern makes the model explain the combination back to you as ordered steps against the column headers of your own export, broadest and cheapest cut first. For each step it says what the filter keeps, what it drops that you might want, and whether it overlaps another filter. Two limits keep it clean. The output is criteria, never a list: it never names an owner or guesses how many rows will come back, so there is nothing to invent. And every filter targets what an owner does with the property or its status - absentee, tenure, portfolio size, tax status - never anything about who the owner is. If a thesis drifts there, the recipe stops and routes it to counsel.

Here is a filter combination and the column headers from my export. Explain it back as ordered steps, broadest cut first. For each step: the column it uses, what it keeps, what it drops that I might want, and any overlap with another step. Never estimate how many rows it returns and never name an owner.
