app/haunts.py merges two free, keyless, properly-licensed APIs rather than scraping: Wikipedia geosearch+extracts (CC BY-SA) and OSM Overpass (ODbL). Every haunt carries its source and a link back. The Wikipedia-article requirement doubles as a notability gate: no article, no pin. That keeps the map to documented history rather than rumour and makes every entry independently checkable. Deliberately excluded — recent crimes at residential addresses. People live in those houses now and get harassed; the families are usually still alive. So crime-framed entries must clear HISTORICAL_CUTOFF_YEAR, anything residential is blurred to ~250m (street, never a door number), and an entry that reads as a crime with no legible date is excluded rather than assumed old. Battlefields, plague pits, gaols, executions and famous historical cases are unaffected. Privacy: the seeker's exact coordinate never leaves the process. Queries snap to a ~1km grid before going upstream — far finer than the search radius, coarse enough that Wikipedia and OSM never learn where anyone is, and it makes the cache shared across a neighbourhood. Two bugs found and fixed by testing against the live services rather than assuming: - Overpass answered 504. The naive query built 28 separate `around:` searches (14 kinds x 2 element types); regrouping to one regex-alternated clause per tag key with `nwr` cuts it to four. - The flat keyword filter put "Fenchurch Street railway station" on the map because its article mentions a fire. Hints are now split into strong (qualify alone) and weak (need two), verified against live results. Known limitation, honestly: all three public Overpass mirrors currently time out or return empty from this host, so the map is Wikipedia-only in practice right now. fetch_overpass already returns [] on any failure, so this degrades quietly and self-heals if a mirror recovers. Also adds the hunter-profiles contract spec. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
