Lane C R21 (v4.0-beta): the five-town density door-soak (ledger #3)

Wave 2 — ran after A's venue cluster-adjacency bias landed (110c828), so the soak reads the
relocated world + A's re-pinned goldens. The carried R20 #6.

Five towns at their new densities, ~25 deterministically sampled doors/town (sample takes one
of EVERY type present, then stride-fills, so the texture classes' first real appearance is
always covered):

  town              shops  sampled  venues  types  worst draws   verdict
  katoomba_real      72      25       3      10       157         PASS
  newtown_real       67      25       3      11       155         PASS
  fremantle_real     79      25       3      11       153         PASS
  bendigo_real       35      25       3      10       154         PASS
  castlemaine_real   23      23(all)  3       8       156         PASS

123 doors: 0 throws / 0 carves / 0 path-fails / 0 over-budget, worst 157 draws (<=350).
typesInTown == typesSampled in every town (all archetypes entered, incl. all 3 venue kinds).
All five towns landed 3 venues -> A's cluster bias + district placement hold at density.

§6 mapping verified live: katoomba cache = 20 heroes + 60 texture (exactly E's 3x cap, heroes
untouched). Texture's first real appearance renders right -- "Blue Mountains Chocolate Company"
(real OSM shop=chocolate) wears milkbar as a believable confectionery counter shop. Texture,
not takeover. Cache->plan deltas are A's counted drops, not an interior concern.

C->F: density verdict GREEN. Docs-only.

## Update 2026-07-16 (round 21, v4.0-beta close) — the five-town density door-soak (ledger #3)
R21 §Lane C (wave 2 — ran **after A's venue cluster-adjacency bias** landed, `110c828`, so the soak reads the
relocated world + A's re-pinned goldens). The carried R20 #6: **every one of the five beta towns at its new
density**, deterministically sampled ~25 doors/town — the sample takes **one of every type present** then
stride-fills, so the texture classes' first real appearance (milkbar/dept/stall on real shops) is always covered.
| town | shops (in plan) | sampled | venues | types (all sampled) | throws | carves | path-fails | over-budget | worst draws |
|---|---|---|---|---|---|---|---|---|---|
| `katoomba_real` | 72 | 25 | 3 | 10 | 0 | 0 | 0 | 0 | **157** |
| `newtown_real` | 67 | 25 | 3 | 11 | 0 | 0 | 0 | 0 | 155 |
| `fremantle_real` | 79 | 25 | 3 | 11 | 0 | 0 | 0 | 0 | 153 |
| `bendigo_real` | 35 | 25 | 3 | 10 | 0 | 0 | 0 | 0 | 154 |
| `castlemaine_real` | 23 | 23 (all) | 3 | 8 | 0 | 0 | 0 | 0 | 156 |
**123 doors · 0 throws · 0 carves · 0 path-fails · 0 over-budget · worst 157 draws (≤350).** In every town
`typesInTown === typesSampled` — every archetype present was entered, including all three venue kinds
(pub/band_room/rsl) and the texture classes. **All five towns landed 3 venues** → A's cluster bias + district
placement hold at density.
**§6 mapping verified live (John's SUBTLE directive, working by construction):** katoomba's cache is **20
heroes + 60 texture** — exactly E's 3× cap, heroes untouched. In-plan (after A's counted drops): 17 heroes
(opshop 10 · book 4 · record 2 · video 1) + 52 texture (milkbar 29 · dept 18 · stall 5) + 3 venues = 72.
The texture classes' **first real appearance** renders right: **"Blue Mountains Chocolate Company"** — a real
Katoomba `shop=chocolate` — now wears `milkbar` (70s geo wallpaper, cube shelves of price-tagged goods, counter,
wall rack): a believable confectionery counter shop. The widening reads as texture, not takeover.
*(Cache→plan deltas — e.g. katoomba 80→72 — are A's overflow/fragmentation drops, counted by cause in A's R20
accounting; not an interior concern, and every surviving door builds clean.)* **C→F: density verdict GREEN.**
Docs-only. C otherwise on-call; my §6 mapping + this soak close both C items for the beta.
