# PROCITY — Round 23 lane instructions (from Fable, integrator)

Date: 2026-07-16 · **v4.0 SHIPPED, the epoch retro is written ([RETRO_V4.md](../RETRO_V4.md)),
and John has chartered v5: [THE REAL SHOP](../V5_REAL_SHOP.md).** Read the charter first — the
tier ladder (parody → static real → live GODVERSE) and the five laws are the epoch's spine.

Round 23 is **v5.0-alpha: THE FIRST REAL CRATE** — one real shop's real stock, riffled and
bought, end-to-end, plus the G3 design doc drafted for ratification. The v4.x tail runs as the
light parallel lane the retro promised. Tag **`v5.0-alpha`** at close.

## The ledger

1. **G2a: the first real atlas (Lane G, on ultra — the round's headline).** Build the per-shop
   atlas pipeline per the R22-reviewed contract (C's ceilings · atlas-per-shop keyed by godverse
   shop id · fail-soft to parody): dealgod inventory → a static atlas + index for ONE real
   Newtown record shop in `newtown_godverse`. Files stay in the G namespace
   (`pipeline/godverse_*`, `web/assets/stock_godverse/**`). Deterministic (byte-identical
   re-run against the same inventory snapshot — snapshot the query result like you snapshot
   Overpass raw). Provenance per the licence law (charter law #3). **This deliverable is
   gating, so per the merge amendment (charter law #5) your branch merges mid-round once
   Fable-m3 reviews.** Ping via G-progress when it's up.
2. **G3: the design doc draft (Lane G + both Fables).** `docs/G3_ECONOMY_DESIGN.md` covering:
   API surface (read stock / price / reserve / buy) · async-enrichment caching (risk #1 — the
   dig never blocks on network) · the determinism boundary (charter law #2) · failure modes
   (server dies mid-session → tier 1 without a stutter) · census↔lot identity matching (risk
   #3, mismatches counted) · **the write-back question stated as a decision for John** (charter
   law #4 — options with trade-offs, no default). Draft this round; ratification is R24's
   kickoff. Nothing server-side ships before it.
3. **The interior side of the real crate (C).** When G's atlas merges: verify the contract in
   the room — the godverse record shop's crates resolve the per-shop atlas through the existing
   `stockAdapter` path, interior draw/tex ceilings hold with real covers, `?noassets` and
   missing-atlas boots fail soft to parody with zero errors. If the contract needs an
   amendment, you own the wording (LANE_C_PUB), G re-emits.
4. **The atlas validator (E).** The format side: a `validate_atlas` check in the pipeline
   (dimensions ≤ C's ceilings, provenance fields present, index↔atlas consistency, determinism
   note) so G's output is gate-checkable on m3 without the dealgod DB. Plus the retro's
   curation item: **the thin-tail clustering floor** — re-bbox toowoomba onto its actual retail
   strip (or retire it, your call, counted either way) using D's median nearest-neighbour
   spacing as the curation metric.
5. **The spacing warn (A).** D's metric becomes law: `validateTownCache` warns when median
   nearest-neighbour spacing exceeds a threshold you pick from the pack's measured spread
   (darwin 27 m alive, toowoomba 388 m dead — plenty of daylight for a line). Warn, not error —
   E curates, the validator flags. Re-pin only what E's toowoomba fix moves.
6. **GIG_RANGE chunk-neighbour fix (D — the carried v4.x item).** The 8.7% blind spot: extend
   `_nearestOpenShop` to the ped's chunk + 8 neighbours. Hot path, so bring the R18-style
   before/after (perf cost, blind-spot elimination, determinism unchanged, byte-identical
   flags-off). Post-release is exactly when this change is safe.
7. **The alpha gate (F, last).**
   a. THE CRATE, end-to-end in a fresh browser: boot `newtown_godverse` with `?stock=real`,
      walk into the real record shop, riffle — **real covers render** — buy, wallet debits,
      the item leaves the crate (tier-1 static semantics: gone this session, back next boot —
      that's correct until G3).
   b. The tier ladder proven: same shop under `?noassets` (tier 0, zero fetch), missing-atlas
      (soft fall to parody), `?stock=real` (tier 1) — all silent-and-fine; classic + default
      gates frozen as ever.
   c. `qa.sh --strict --matrix` green (the matrix now includes E's toowoomba fix), notes §23,
      README one-paragraph v5 teaser, tag **`v5.0-alpha`**, push.

## Laws

The charter's five (offline · determinism boundary · licence · write-back · two-studio) plus
everything inherited. Golden discipline: only E's toowoomba re-bbox may move a town golden
(amendment law, one commit). No server code anywhere this round — the G3 doc is paper.

## THE EXACT RUN ORDER

1. **Start together: G (atlas + doc draft, on ultra) + E (#4 validator + toowoomba) + A (#5
   spacing warn) + D (#6 GIG_RANGE).** All disjoint.
2. **When G's atlas is up and Fable merges it: start C (#3).** E's validator should be ready to
   run against the merged atlas — coordinate in G-progress.
3. **When C passes and E/A/D are in: F closes (#7)** — the crate, the ladder, the tag.
4. **G3 doc review runs asynchronously all round** — both Fables comment in the doc; it lands
   ratified-or-revised at R24 kickoff with John's write-back ruling.

Waves: **[G, E, A, D] → [merge, C] → [F]**, with the doc threading through.

## Standing

- **John — one decision incoming, not blocking this round:** the write-back question (does an
  in-game purchase ever touch real thriftgod inventory — sandbox, reservation, or full
  write-back?). It arrives framed with trade-offs in the G3 doc at R24 kickoff. FYI: G's branch
  merges mid-round this epoch when its deliverable is gating (charter law #5); item-photo
  licensing stays in-house-green, flagged before anything public.
- **B — deliberately light this round** (you've carried heavy since R16): on-call for C if the
  crate render surfaces anything street-side, plus first pick of the v4.x polish list next
  round (awning ripple and the tram-stop tri diet are yours when you want them).
- **v5.0-beta preview (do not start):** every hero shop in 1–2 godverse towns stocked · mint()
  pricing baked into atlases · fitzroy_godverse if the census is dense there · the dig UX for
  real items.
