Notes

My target communities

Preference feeds the community score (1 = tolerable, 5 = ideal). With "Only my communities" on, listings outside this list are filtered out.

Property-type preference

Feeds the property-type score. The hard filter (which types show at all) lives on the Listings page.

Rules

Stale after (days)

Down payment %

DOM leverage half-life (days)

Days on market accrues only while a listing is active, from the moment it entered this tracker. The leverage curve is 1 − e^{−DOM / scale}; at 45 days it's ~0.63.

Listings feed (later)

Dataset JSON URL

Stored, not fetched. The seam is Ingest.upsert() plus FeedAdapter.mapRecord() in the script; every listing, pasted or fed, enters through the same path.

Export

Everything: listings with full history, communities, weights, settings. Price history is the part you can't rebuild, so keep a copy.

Import (merge)

Merges by listing id: new ids are added, existing ids get their histories unioned and the newer field values kept. Communities are unioned. Nothing is deleted.
