m3ultra a78dc76f84 Lane A round 18: the real-graph lift — OSM ways → CityPlan street graph (v4.0-alpha REAL ROADS)
The epoch headline (ledger #2). A v2 cache's roads[] now builds the CityPlan street graph FROM real
OSM geometry instead of marching shops onto synthetic avenues. SAME CityPlan schema out — B/C/D/F consume
it unchanged by contract. roads absent ⇒ the v1 marched fallback, so classic/gig/osm goldens are FROZEN.

plan_osm.buildRealRoads: project ways+shops to the local metre frame → simplify each way (Douglas-Peucker
eps~6m, the fidelity knob) → snap coincident points (<=3m) to shared nodes = real intersections →
straight-segment edges → classify main by OSM highway class + shop density → seat each shop on its NEAREST
real edge (real order, real side), marched with regularised spacing + a deterministic overlap-resolve pass.

Fidelity (charter risk #4): real edge/order/side + regularised spacing — NOT pixel positions (real shops
overlap; the no-overlap invariant is load-bearing). Alpha failure list in LANE_A_NOTES §R18: overflow drop
on short edges; intersections = shared-coordinates only (a D sim-graph risk); per-edge frontage-strip
blocks not planar faces (a B ground-render item); crowded-intersection overlap-resolve.

Proven: a committed synthetic irregular graph (main + two cross streets + a real intersection + an acute
angle + a dead-end lane + a curve) passes the FULL structuralSuite + gig district + byte-identical
determinism; mutation-tested non-vacuous (flip the facade facing → 'faces its frontEdge' fails). Robust on
messy inputs (single road, coincident dups, disconnected ways, all-roads-too-short → marched). All osm
goldens frozen; E's 4 trailing caches pinned on v1; katoomba_real UNPINNED (its real-roads golden pins when
E lands roads — the A->E->A finalization). selfcheck ALL GREEN 16810/16810; scaffold + consistency GREEN.

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." AE 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 AE into one seed-to-town game + QA gates (after AE)

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 24 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

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.
