§0.1 — ground.js adopts Lane A's corridor law. The road quad narrows from the whole
corridor to the carriageway and the EXISTING merged footGeos class extends inward to
meet it, consuming `vergeBand(e)[0]` (not `roadWidth/2` — per A's mid-round correction,
so the geometry and A's corrected gate read the same number).
MEASURED, fresh boots, port-isolated no-store servers (:8178 = HEAD control, :8177 =
treatment), 2560x1440:
synthetic ground 5 draws / 224 tris -> 5 draws / 216 tris
walked spine, 102 steps @ 8 m: worst 276 draws BOTH; sum of draws
20,081 BOTH (identical at every step); 8 bookmarks identical draws
katoomba_real ground 4 draws / 9,932 tris -> 4 draws / 9,644 tris
walk 120 steps: worst 100 draws BOTH; sum 7,703 BOTH
+0 draws is proven, not asserted. Tris go DOWN (-8 / -288): the charter's "~2k tris" was
an estimate against a class that already existed. Honest number, stated loudly.
Surfaces verified by RAYCAST, not by reading the code (offset from centreline, topmost hit):
main@28 road 0-4.75 | kerb 5 | footpath 5.25-17.5 (band [5,14])
main@24 road 0-5 | footpath 5.25-15.25 (band [5,12], real)
side@12 road 0-3 | footpath 3.25-9.5 (band [3,6] — 72% of the corpus)
lane@8 road 0-4 | footpath 4.25-9 DEGENERATE band [4,4] => pre-ruling geometry
lane@4 road 0-1.75 | kerb 2 | footpath 2.25-5.25 (synthetic, also unchanged)
arcade footpath 0-6.5, NO road quad, NO kerbs (1,102 corpus edges)
RESIDENTIAL side@14 road 0-2.75 | kerb 3 | GRASS 3.25-6.75 | footpath 7-10.5
The lane case branches on `outer <= inner`, never on a band literal.
Posters: 14 of 14 stood inside painted bitumen before; 0 of 14 after. Not one poster moved
— the ground did.
ONE DEFECT FOUND AND FIXED IN THE ROUND. The first cut painted every intersection shut:
a 12.5 m footpath crosses the perpendicular CARRIAGEWAY where a 3.5 m one only ever
clipped a far corner. Screenshotted, rejected, and fixed by putting the carriageway on
top (ROAD_Y 0 -> 0.04 under the flag): roads run through junctions, footpaths stop at the
kerb they meet. Verified on the real graph's worst 4.3-degree junction.
?verge=0 ships permanently — the gate's falsifiability control. Proven EXACT, not merely
similar: ground vertex+uv hashes identical to the HEAD build (c4c72181 / c111d968 /
1a80ebcd / 12c1241b / fd0d3211), and the same detector goes RED on the default boot.
CLASSIC IS FENCED, NOT AMENDED (the R31 dig-flip pattern). ?classic=1 forces verge off, so
the covenanted town's render does not move on a render-side ruling. Proven twice: identical
ground geometry hashes AND identical ground-only rendered pixels at three poses
(79df268c / 91564001 / a09d1e52), while the default boot differs at all three. If Fable
wants classic to take the footpath too, that is an amendment ruling and a one-token change.
§0.4 — the chunk lifecycle seam. The producer has fired since R3 and Lane D's consumer has
existed since R3, but nothing could connect them: createChunkManager never handed `ctx`
back, so a consumer holding only PROCITY.chunks had nowhere to attach (measured on HEAD:
`!!chunks.ctx === false`). Now `chunks.onChunkBuilt(fn) -> unsubscribe()` for many
consumers plus `chunks.ctx` for the original single slot. Proven live: 136 build / 144
dispose events over a 40-step walk; payload {cx,cz,buildings,furniture,data} with
key === `${cx},${cz}`; a second consumer does not clobber the first; the ctx slot fires;
unsubscribe silences; a THROWING subscriber does not take the streamer down.
ZERO behaviour change when nobody subscribes: a 102-step walk recording
[draws, tris, chunks] per step hashes ceb1ec66 on BOTH builds.

Note on night_crowd (Lane F, R10)
Re-framed to the tighter, readable "one lit shop in a closed town" composition. It does not show a
standing street crowd, and that is not a framing bug: Lane D's night patronage parks ducked-in patrons
hidden inside the shop (they become the interior browsers seen in browsers.png), and seed 20261990's
video shop sits on a low-traffic corner, so none gather visibly outside (tested: 0 patronage / 0 visible
at night). The town's night life is the interior presence + the neon-vs-CLOSED mood. A visible outdoor
night queue would need a new Lane-D mechanic (loiter-outside-the-openLate-shop) — parked for v3. The
~20 fps in night captures is a headless-chromium software-GL artifact (the scene is light, ~128
draws / 65k tris); on real hardware the night scene is not a perf concern.
Regression workflow
Before a risky change, snapshot the good state into before/, then re-run v2_tour.py and eyeball
v2_contact.html. Process rule (R10): any shot containing a humanoid gets an explicit
"figures human-sized relative to doors/fittings: yes" line in the progress note — actually look.
