Extend build_towns.py: bounded way[highway](bbox) out geom per town -> raw cached in-repo -> roads[]
in A's v2 contract ({id,kind,pts:[[lat,lon]]}, kind=raw OSM highway class). katoomba_real is now
schema v2 with 484 real streets (Bathurst Rd, Cliff Drive, ...). Fidelity cut (charter risk #4, flagged
to A): fetch every ROAD_KIND tier -> raw; EMIT the town street tier only, excluding service/track/
footway/path/steps/cycleway (1461 of 2506 Katoomba ways = bushwalking tracks/sidewalks/stairs/driveways).
A's lift builds a real town from it (verified): 484 streets -> 872 nodes/799 edges (main 232 side 531
arcade 36) -> 12 blocks, 20 lots, 3 venues (pub/band_room/rsl), 12 gigs. pickVenues lands venues on the
real graph (ledger #2 met).
FINDING for A (alpha failure-list, charter risk #3): on the real graph, spine posters overhang crossing
carriageways -- selfcheck kerb-clearance fails on 4 seeds (-1.6 to -2.5m; e.g. seed 20261990 poster 50 vs
edge 58 = -2.42m). Same class as A's R15/R16 corner-poster fix, now on real cross-street geometry. Owner:
A (pickVenues/POSTER_CLEAR on the real graph, the 'A again' harden step) -- my roads data is VALID (cache
validates; failures are plan-level poster placement). Golden settles after A's fix (pre-fix 0x6014a8e6).
ODbL: raw roads committed, SOURCES.md updated.
-> Lane A: katoomba roads live; harden the lift + resolve the poster finding + re-pin the golden.

The half-day handshake so E's build_towns.py can fetch road geometry (ledger #1). Optional roads[]
on the town cache carries real OSM way geometry; plan_osm's graph lift (consuming it) follows in the
next commit. v1 caches (roads absent) stay valid — the marched fallback — so nothing shipped regresses.
- validateTownCache accepts schema procity-town-cache/1 AND /2; when roads[] is present each road must be
{ kind:string, pts:[[lat,lon],…] } with >=2 finite points (else rejected); <2 pts dropped, unmapped
highway kind → 'side' (warnings). ROAD_KIND maps OSM highway=* → CityPlan edge kind (main/side/lane/arcade).
- Full v2 contract in web/assets/towns/README.md (the doc E builds to): shape, road validity, the kind map,
the fidelity knob (charter risk #4), and the bbox-bound-the-roads rule.
- E's 5 existing v1 caches re-validate clean; selfcheck ALL GREEN.

Ledger #4 (warm-up): publish.py --verify no longer false-flags non-procity_ published assets
(sit.glb, vintage-cash-register). It compares the _published.json name record against the depot's
full file list (fetch_depot_files) instead of a procity_ prefix filter; only OUR namespace flags as
unrecorded. --verify now: all 39 recorded assets live.
Ledger #6 (the scout): new pipeline/build_towns.py ports thriftgod build_city()'s Overpass route to
per-town caches in A's procity-town-cache/1 contract. 5 real compact AU towns under web/assets/towns/
(katoomba/newtown/fremantle/bendigo/castlemaine, 6-21 shops, spans <2.4km): bounded Overpass query ->
raw cached in-repo (re-runs never re-fetch) -> dedupe/suburb-fill/parody (trademarked chains only;
indie shops keep real OSM names)/type-map. Deterministic (byte-identical re-run, no RNG). ODbL:
SOURCES.md licence table + license/attribution on every cache. All 5 boot through the full
structural+gig suites (selfcheck 16596/16596 green; synthetic golden 0x3fa36874 unmoved). Overpass
fetch John-authorized (Standing #2).
-> Lane A: caches live under web/assets/towns/; pin the per-town goldens selfcheck printed (katoomba
0x61760542 newtown 0x95978b45 fremantle 0xee9fd09a bendigo 0x5e3e76a6 castlemaine 0xf1a628a1) +
feed through plan_osm. E->A handshake.

The real-map scout (ledger #6), A's half. Scope fence held: NO new plan features, NO golden moved
(classic 0x3fa36874, gig 0xb1d48ea1, all three osm fixtures frozen). The scout proves the EXISTING
?plansrc=osm contract eats real geography.
- The town-cache contract (published FIRST — E builds build_towns.py to it). plan_osm.js gains
validateTownCache() (authoritative {ok,errors,warnings}), registerTownCache(), a generatePlanOSM(..,
{cache}) seam, and TOWN_CACHE_SCHEMA/MIN_TOWN_SHOPS(6)/MAX_TOWN_SPAN_M(5km). Shape: {schema,key,town,
source,license,attribution,center{lat,lon},shops[{id,name,type,lat,lon,suburb?}]}. Home declared:
web/assets/towns/<key>.json (+ README.md full spec). Documented in CITY_SPEC v3.2 + LANE_A_NOTES R17.
- plan_osm hardened: blank name -> registry label; the validator gates finite center/coords + a >=6-shop
floor and warns on unknown-type(->opshop)/dup-id/span>5km. Proven vs thriftgod's real 2,828-shop
city_source.json: boots a valid plan, 0 bad coords, 0 'undefined' names.
- selfcheck: a committed synthetic-adversarial contract suite (valid-messy caches boot + pass structural/
gig; invalid reject; wide-spread warns; registry seam) + an auto-loader for web/assets/towns/*.json
(validate -> suites -> pin per-town golden), empty and green until E lands caches. ALL GREEN 15277/15277.
- v4 charter risk list (LANE_A_NOTES R17): the MEGA-STRIP (unbounded bbox -> 11.6 km strip; town selection
is E's real lever, warned >5km); sparse compact towns (2 km inner-Canberra held 6 shops); osm facades
clear (rows 54 m apart) so R16's bias is a no-op on real towns.
E->A handshake: E drops a cache in web/assets/towns/, the selfcheck prints its golden, I pin it.
