The carried-over OSM plan source (no-showed R4–R5) lands complete, invariants green — a
second CityPlan producer behind the same contract, so B–F consume it unchanged.
- osm_fixture.js: 95 REAL inner-Melbourne secondhand/charity/music/book/toy/antique shops,
extracted deterministically from thriftgod city_source.json (Overpass cache), imported as a
module ⇒ ZERO network.
- plan_osm.js: generatePlanOSM(seed) — project lat/lon→metres, bin shops into latitude-band
avenues off a spine (real row + real E–W order preserved), march into a valid non-overlapping
CityPlan, centre on origin, report true 362×486 bbox, real shop names, one openLate video.
- index.js: generatePlanFor(seed, source) selector — default 'synthetic' BYTE-IDENTICAL
(golden 0x3fa36874 untouched); 'osm' → the importer. generatePlanOSM exported for F.
- selfcheck.js: parameterized by source — OSM runs the full structural invariant suite
(frontEdge/facing/no-overlap/chunk-coverage/finite/JSON/determinism/openLate) + its own
golden 0x34cfdec0; synthetic-only brief checks skipped. ALL GREEN 1362/1362.
- map.html: ?plansrc=osm renders it (reference wiring for F). Screenshot in docs/shots/laneA/.
- CITY_SPEC: plan-source note; LANE_A_NOTES R6: seam + goldens + shape-diffs for F's gate (F2).
Honest cut: street geometry regularized (real row+order drive it, exact metres do not);
name-parody deferred. qa.sh --strict GREEN.
