PROCITY

A standalone, procedurally generated, fully walkable 90s-Australian shopping town — every building enterable (the Vuntra City trick), every interior seeded and themed: record stores, op shops, toy shops, book barns, video rental, pawnbrokers, milk bars, market stalls. Built on the proven house stack (three.js r175 vendored, plain JS, no build step) and the asset DNA of 90sDJsim + thriftgod. v1 is the system; the GODVERSE/BaseGod real-item content plugs in later.

Run

cd web && python3 -m http.server 8130

The lanes (parallel Opus 4.8 sessions)

Each lane is a self-contained prompt. To run one, start an Opus session in this repo and say: "Read docs/LANES/LANE_X_….md and execute it." A–E are parallel-safe (disjoint files, standalone test pages); F integrates after they land.

lane	mission	owns
A — CITYGEN	seed → CityPlan data (streets, blocks, lots, shops) + 2D map	js/citygen, js/core/registry.js, map.html
B — STREETSCAPE	chunk-streamed instanced 3D town + game shell	index.html, js/world
C — INTERIORS	every door opens: seeded themed shop interiors	js/interiors, interior_test.html
D — CITIZENS	rigged-near / impostor-far NPCs + shopkeepers	js/citizens, citizens_test.html, models/
E — ASSETS	audit ultra's library, normalize GLBs, skins, manifest	pipeline/, assets/
F — INTEGRATION	wire A–E into one seed-to-town game + QA gates	(after A–E)

Already in the repo

• web/vendor/ — three.js r175 + addons (vendored from 90sDJsim; no CDN at runtime).
• web/assets/gen/ — 69 generated texture skins (25 shopfront facades, 10 skies, 10 grounds, 8 wallpapers, 16 interior surfaces) inherited from thriftgod + 90sDJsim, style-locked.
• web/js/core/ — frozen shared modules: prng.js (seeded-everything law), loaders.js (fail-soft promise-cached GLB/texture + 3GOD depot), canvas.js (text planes).

House laws (short form — CITY_SPEC has the fine print)

Seeded everything, Math.random banned in gen code · the game must run with zero assets · instancing from day one · canvas text, no font files · characters = shared base rigs + one clip bank, canonical sources live outside this repo · 🟢 web-ok licensing only.

v3.1 — THE FLIP: the town shows its best by default

The Friday-night layer soaked through alpha, beta, and the v3.0 release — so v3.1 flips it on by default, and the mature v2 flags flip with it. Boot the plain URL and each town seeds 2–4 venues (pub, band room, RSL) with a full seeded week of gigs, town-wide posters, and a Friday night that reads: a 4-piece band (trio + a seated drummer) with real instruments, a mixed crowd, an outdoor queue, a per-venue cover charge, muffled gig spill + walla and applause, town-wide streetlamp pools, and identity continuity — the ped you followed in is in the crowd. Plus weather, the tram, and the parallax interior-window shader, all live by default.

The covenant moved, it didn't disappear. ?classic=1 boots the exact v2 town — byte-identical forever (synthetic golden 0x3fa36874, zero gig layer, zero fetch delta). That is the new frozen regression target; the default boot is deterministic to the gig golden 0xb1d48ea1. Asset-free (?noassets=1) composes with the default boot and stays silent-and-fine.

Flags — the four headliners are ON by default, each with a =0 opt-out; ?classic=1 is the master off:

flag	default	what
?classic=1	off	the exact v2 boot — all four below off, byte-identical to the frozen baseline
?gigs=0	on	the gig district — venues, week schedule, band/crowd/queue, cover, posters, night pass
?weather=0 · ?tram=0 · ?winmap=0	on	seeded weather · the tram loop · the parallax interior-window shader
?roster=v1 · ?pop=N	stream	chunk-streamed citizen density is the baseline; ?roster=v1 restores the fixed roster
?dig=0 · ?stock=real	dig on	crate-riffle on record bins · real GODVERSE sleeves in the stock
?noassets=1 · ?plansrc=osm · ?mute=1 · ?dbg=1	off	asset-free (zero network) · OSM plan source · silence · the window.DBG capture/soak harness
?plansrc=osm&town=<key>	—	boot a real Australian town: fixtures melbourne/katoomba/silverton, or a real OSM cache bendigo_real/castlemaine_real/fremantle_real/katoomba_real/newtown_real (ODbL, web/assets/towns/SOURCES.md). v4.0-alpha REAL ROADS: a cache with roads[] (schema v2) builds the CityPlan street graph from the town's actual OSM streets — walk Katoomba's real main street; without roads[] a cache marches onto synthetic avenues
?seed=N	20261990	town seed

Release tour: docs/shots/release_v3_1/contact.html — the money shots on the default boot, plus a ?classic=1 before/after. QA: tools/qa.sh --strict (classic regression + default-boot gate + smokes + no-giants) --soak (the full-week soak); the seated drummer passes the no-giants gate at the seated stature band [0.9,1.5] m.
