1. validate_atlas (the G2a format gate). pipeline/validate_atlas.py, wired into validate_manifest so it
runs in qa gate 3. Judges Lane G's tier-1 atlases from the COMMITTED FILES ALONE -- no dealgod DB, no
network. No atlases yet => clean pass, so it's in place before G's lands. Enforces: provenance
{license, attribution, generator, snapshot} (charter law #3 + determinism); NO private-individual item
fields (law #3); 1 atlas/shop hard cap 2 (C §7.1); <=1024², 2048² only for a 60+ item shop (C §7.2);
declared atlas_px == the atlas's REAL pixels + every listed atlas exists; schema/UV/bands/dup-ids
(C §7.3). The licence string is PRINTED, not pattern-matched -- clearing photos for public release is
a human call, so the gate surfaces it. Dependency-free PNG/WebP header parser. Tested against a
10-case matrix (real 2048² WebP + 1024² PNG): good passes clean, all 9 violations caught.
2. toowoomba RETIRED (my call, counted). Tried the re-bbox FIRST: 3.0km CBD-wide -> 1.6km on the Ruthven
St heart. It fixed the named metric (median NN 395.7 -> 89.4m raw, 'passes') but made the real thing
WORSE: hub density 3/12 -> 2/12 within 160m, the pack's worst (D's alive-darwin is 7/12). Its shops
are PAIRS strung along a road, not a high street; densest 300m cluster is 3 shops (< MIN_TOWN_SHOPS),
so no tighter box exists. Shipping it would have gamed the number while leaving a town nobody shops in
(D: 0 finds / 1417 checks). Config entry kept commented with the rationale. Pack: 21 real + 1 godverse
= 22 rostered, 1180 shops, all 8 states/territories (QLD keeps westend). selfcheck ALL GREEN 152015.
-> Lane A, before you freeze the spacing warn (#5): (a) your validator sees the CACHE (raw lat/lon) but
D's numbers are SEATED (post-lift) -- darwin is 27m seated vs 68.3m RAW, so a threshold picked off D's
table would FALSE-WARN darwin; calibrate on the raw spread (daylesford 11.6 ... braddon 119.2,
ballarat 254.6 -- a ~200m line has daylight). (b) median NN alone is GAMEABLE: my re-bbox improved it
4.4x while the town got worse -- the hub fraction is the discriminator, and my raw hub metric
reproduces D's darwin exactly (7/12), so it's directly encodable (alive ~38-75%, dead <=20%).
(c) ballarat is a SECOND spread town D's two-town comparison missed (NN 254.6m, hub 4/20 = 20%) -- it
will trip your warn, correctly. Not retired: the ledger named toowoomba only.

Town-cache data sources & licence (web/assets/towns/)
Lane E owns this file (ROUND17 ledger #6). Every real-town cache here is derived from
OpenStreetMap data and ships under OSM's licence. This notice + the license/attribution
fields on every <key>.json are the attribution that travels with the data.

The caches are a produced work derived from OSM via the Overpass API (overpass-api.de), filtered
to on-theme shop=* points, deduped, suburb-filled, and type-mapped by pipeline/build_towns.py.
Attribution ships in-repo (this file) and in every cache ("license":"ODbL 1.0",

Provenance table
index.json is the machine-readable roster (key/town/state/shops/roads) — read it rather than
hardcoding a list. Every cache carries the same terms; per-town numbers live in each cache's counts.
The pack: 21 real towns · 1180 shops · 295 heroes (+ Lane G's newtown_godverse = 22 rostered in
index.json), every one fetched from OSM Overpass with a bounded per-town bbox, ODbL 1.0, raw snapshots
in _raw/ (shops + roads per town), fetched 2026-07-16.

Retired (R23, counted): toowoomba_real — D's clustering audit measured it DEAD (0 patronage finds
in 1417 checks); a re-bbox onto the Ruthven St heart fixed the spacing metric (median NN 396 → 89 m) but
made the hub worse (2/12 within 160 m, the pack's worst), and its densest 300 m cluster is only 3 shops.
Cache + raw snapshots removed; the config entry stays commented with the rationale. See LANE_E_NOTES R23.
The density widening (v4.0-beta, ROUND20 ledger #2)
The fetch covers the secondhand heroes plus the everyday main-street texture (bakery/cafe/deli/
newsagent/chemist/clothes/hardware/greengrocer/…), mapped to existing registry types per C's
LANE_C_PUB §6 table. Tasteful staples only — no vehicle/fuel, funeral, storage, industrial, or pure
services. cafe rides amenity=*; everything else is shop=*. Per John's subtle directive the
heroes are never subsampled and texture is capped at 3× the hero count (deterministic
sha256(townKey:osmId) rank); every drop is counted in each cache's counts.textureDropped.
index.json — the towns roster
{schema:"procity-towns-index/1", generated, license, attribution, towns:[{key, town, state, shops, roads}]}. Same ODbL terms as the caches. Consumers (B's selector) derive the town list from this
rather than hardcoding.
Raw responses (_raw/)
The raw Overpass JSON is cached in-repo (wrapped with fetchedAt, endpoint, query, bbox):
_raw/<key>.overpass.json (shops) and _raw/<key>.roads.overpass.json (OSM highway ways, schema v2).
Re-runs reuse the raw cache and never re-hit Overpass — the fetch is outward-facing network
(John-authorized scout, once per town). --refetch forces a deliberate re-fetch. selfcheck.js reads
only top-level *.json, so _raw/ is never loaded as a cache.
Roads — schema v2 (ROUND18, v4.0-alpha REAL ROADS)
A v2 cache carries roads[] — the town's real OSM street geometry (highway=* ways), same ODbL licence
and attribution as the shops. Fidelity cut (charter risk #4): the raw fetch grabs every ROAD_KIND
tier, but the emitted roads[] is the town street graph only — drivable roads + pedestrian malls;
service/track/footway/path/steps/cycleway are excluded (in Katoomba, 1461 of 2506 ways —
bushwalking tracks, sidewalks, stairs, driveways). The excluded tier stays in the raw response if a
tier is wanted back. katoomba_real is v2 (the alpha); the other towns' roads land as data-only.
Names — parody vs factual
Big trademarked charity/franchise chains are parodied in build_towns.py (Salvos→Slave-ohs,
Vinnies→Sinnies, Anglicare→Tanglecare, Cash Converters→Cashtheists, …) for the game's comic tone.
Independent shops keep their real OSM name — factual, publicly-mapped POI data under ODbL. No
private-individual data is carried (name/type/coordinate/suburb only).
