m3ultra 0ee7a84710 Lane B R39 39.2: THE FOG — the map shows what you walked past, and is finally readable
minimap.js drew every lot in the plan from the first frame (493 shops on the synthetic, one M
press, against 5,330 m / 4.8 game-days of walking to earn it). It now draws what has been walked
past AND FRAMES ITSELF TO IT — a shop lot goes 0.83x1.11 px -> 29.4x39.2 px on bowral_real, 35.3x.

ZERO DRAWS, measured as an A/B: two port-isolated no-store servers, HEAD vs treatment, the same 15
stations x 4 yaws compared as JSON before either sweep runs. Draw calls IDENTICAL on 60/60 samples
at noon and at night; with the gig layer off both sides (the venue queue's async rigs were the only
noise) NIGHT is identical in draws AND triangles. Map mode cannot cost a draw structurally: the
frame loop never calls composer.render() in the map branch.

- discovery.js (new): a 25 m PROXIMITY PROBE, not onChunkBuilt (R=2 => the outermost live chunk
  corner is 181 m out), on a plan-derived spatial hash — 1.09-1.37 us a probe, every 6th street
  frame = every 0.46 m at WALK. Plus a side test: you must be in FRONT of the shopfront. Control
  with a red arm: walking the synthetic's two service laneways, radius-only reveals 93 shops, the
  shipped probe 59 — 34 refused through the back wall; on the arcade it refuses 0 of 17.
- save.js: optional `known` block under the delta law, keyed by TOWN (re-derived: 23 caches x 3
  seeds, shop/edge ids and lot geometry all identical; the synthetic alone keys @<seed>). Bounded
  by the plan (max 493 shops / 2,593 edges) at 8,192, 64 towns FIFO, ints only. Whole corpus fully
  learned = 137,547 B (2.6% of quota); 482 B after a 500 m outing. Eight reject arms demonstrated.
- classic BY CONSTRUCTION: createMinimap(plan, null) is the pre-R39 map and the file has no flag
  test at all. ?classic=1 / ?fog=0 / ?game=0 map canvases are hash-identical to HEAD's.
- Lane A's address layer consumed (getTownCache + createAddresses): street names along walked
  streets, deduped; the synthetic gets district labels from the same line. No town-type branch.

FILED, NOT FIXED: index.html:384 (Lane D patronage door points) and :450 (the R32 spawn) use
(-sin ry, -cos ry) — the BACK of the building. buildings.js:410/583-597, dbg.js:53 and minimap.js
all use local +Z. Measured against each lot's own frontEdge the +sin point is 0.00 m from the kerb
and the shipped one 15.25 m the wrong side, 493/493 and 72/72 shops. At the shipped spawn 0 of the
shops within 25 m are in front of you on all four towns tested; at the corrected one, all of them.
Two characters, but it moves the default boot's opening pose mid-round — Fable's call.

# Lane B — Round 39, THE FOG (item 39.2)
Taken in a fresh context on port-isolated **no-store** servers (`:8591` treatment, `:8592` =
`git archive HEAD`), assets/vendor symlinked so the other lanes' mid-round waves are identical on
both sides. Every number behind these pictures is in `docs/LANES/LANE_B_NOTES.md` §39.
| file | what it shows |
|---|---|
| `fog-00-head.png` | **HEAD, synthetic** — all 493 shops handed over on the first M press, 26,506 shop-colour px |
| `fog-01-before.png` | **R39, fresh boot** — 0 shops known, the 240 m frame, a 25 m scale bar |
| `fog-02-after.png` | **R39, after 900 m** — 113 shops, 7 segments, A's district labels (*"the south end of the main street"*) |
| `fog-00-head-katoomba_real.png` | **HEAD, katoomba** — 993 edges of grey spaghetti; at 1.42×1.89 px the 72 shops rasterise to **zero** pixels of their own colour |
| `fog-01-before-katoomba_real.png` | **R39, fresh boot** — the 240 m frame, a shop lot at 29.4×39.2 px |
| `fog-02-after-katoomba_real.png` | **R39, after 900 m** — 34 shops on **Katoomba Street**, with **Edwards Street** running off it (Lane A's address layer) |
| `map-classic.png` | `?classic=1` — the pre-R39 map, hash-identical to HEAD's |
| `spawn-*-SHIPPED.png` | the default boot's spawn pose today: a footpath facing a plaza, **not one shopfront in frame**, 0 shops discovered |
| `spawn-*-FRONT-NORMAL.png` | the same pose recomputed with the front normal `buildings.js`/`dbg.js`/`minimap.js` all use: **under the awning, sign at your shoulder**, 4 shops discovered |
