m3ultra 2f4ab5912f Lane B R26 (v5.0-beta): the stocked shopfront reads from the footpath
Ledger #5 — B's polish pick. A stocked godverse shop now tells you it's
diggable before you reach the door: a crate of seeded spines under the shop
name, and a warm-lamp-over-crates room behind the glass.

Cost: +0 draws / +0 tris. The mark is painted into the chunk's EXISTING
sign-atlas cell; the window cue rides the EXISTING per-shop aTint attribute.
Nothing new is allocated or submitted.

The manifest is the authority, deliberately NOT the godverseShopId key: keyed
means "has a stock identity", the manifest means "a crate is actually here".
Marking keyed-but-unstocked shops would advertise a crate the shop hasn't got
— the street would lie. The mark does not leak tier: "you can dig here" is
equally true of real and mint; provenance belongs on C's price card and in E's
gates. (Second job for ledger #6's manifest, free.)

Measured — true A/B at one pose, manifest 200 vs 404:
  spine-marked sign cells   0 → 3 (18,768 exact-palette px)
  stocked window tint verts 0 → 36
  street_noon               65 draws / 115,502 tris → UNCHANGED
Stocked shopfront (Goulds Books, footpath): 85 draws / 144,730 tris — inside
street law (<=300 / <=200k). Cues agree with ground truth: 3 stocked shops
live → 3 marked cells, 9 stocked window quads.

Covenants re-proved (the prefetch is new code on the boot path), tested with
the manifest present on disk so a stray fetch would 200 and be unmissable:
  ?classic=1        0 keyed, 0 stock fetches, 0 errors  (zero-fetch covenant)
  default synthetic 0 keyed, 0 stock fetches, 0 errors
  manifest 404      18 keyed, fail-soft, 0 page errors

Three traps, self-caught: (1) a module-load fetch would have put a fetch delta
on ?classic=1 — restructured to a lazy reader + plan-driven prefetch, keyed
plans only; (2) the lazy trigger alone raced the first chunk build, so the
first stocked shop you approach built unmarked — prefetch moved to
createChunkManager, before any chunk builds; (3) the first "zero cost" was
VACUOUS (manifest never fetched, so nothing was applied) and the first pixel
detector reported 60 marked cells with no treatment at all — replaced with an
exact-palette signature that reads 0 in control. Vacuous-gate law applies to a
lane's own verification too. Corollary: force-cache serves a deleted file
(transferSize 0, status 200 while disk 404s) — poison the cache or you are
testing your own memory.

B consumes stock_godverse/index.json read-only and emits nothing into it; the
temp manifest used to prove this round was deleted — the directory is G's.
Shape-tolerant + fail-soft, so G's real emission needs no coordination with B.
