PROCITY — Round 27 lane instructions (from Fable, integrator)

Date: 2026-07-17 · R26 wave-4 verdict: C and E landed the mint-id fence, and both wrote the same honest headline — "the rule was the stale thing, not E's check." C owned its stale §7.2a squarely (second time a C contract line met a case written after it and another lane took the red); E proved the fix is stronger than the rule it replaces (the easy green was dropping the prefix check; instead the prefix is now a sourcing-scoped namespace fence). The epoch's four holds now all trace to the same species — a rule meeting a case written before the case existed — and all four were caught before they could lie. The system is working exactly as designed.

Open: F's wave-4 step 3. The beta tag is one re-run away. Round 27 opens there, then closes the epoch: v5.0 — THE LIVE CRATE.

WAVE 0 — F tags the beta

qa.sh --strict --matrix (the 6/1/0 should flip to 7/0/0 — E's fence is in, C's line is law), tag v5.0-beta, push. Nothing below starts until this lands.

Then: v5.0 — THE LIVE CRATE (tier 2, per the ratified G3)

The charter's last rung, under John's binding A-then-B ruling: read-live, sell-sandboxed — /reserve and /buy stay ABSENT (not stubbed; a sandbox a config typo can flip isn't a sandbox). The server enriches, never gates: every boot path, gate, and tag works with the server dead. Scope honesty up front: if tier 2 proves bigger than one round, F holds and we split — four holds have proven the pattern; nobody forces an epoch close.

The ledger

1. The read endpoints (G, on ultra — server-side). G3 §4 as ratified: GET /godverse/v1/shop/<godverse_id>/stock (items + gone:[sku] + etag) and /crates (the rotation menu), read-only over the live POS, serving metadata only (covers stay static tier-1 files — the API never serves the atlas). Monster Robot is the only real shop; that's the point — one shop, live, true. Deterministic-where-possible discipline: same POS state → same response (etag'd).
2. The tier-2 reader (F, with C's seam). Async enrichment at room build: on entering a keyed real-sourced shop, the shell fires the stock read (timeout-guarded, etag-cached) and the crate applies the gone list + live prices when the response lands — the dig NEVER blocks on the network (charter risk #1). C: if the crate needs a post-build content-adjust hook, that's your seam to publish (half-day rule); if the existing adapter re-read covers it, say so and F wires direct. Server dead / unreachable / slow → tier 1 exactly, silently.
3. The kill-the-server gate (F — the epoch's defining gate). Three arms, all falsifiable: boot server-up → live fields present (assert etag/gone consumed); kill the server mid-session → next read degrades to tier 1 with ZERO console errors and no stutter (frame-time measured across the failure); boot server-down → pure tier 1, byte-identical to the beta behaviour. This is charter law #1 made a gate. It runs as its own smoke class — server lifecycle is controlled by the gate itself, so the assertion is deterministic even though live stock isn't.
4. Sold-means-gone, sandboxed (F + G). The server's gone list removes items from the live crate read (a record sold IN THE REAL SHOP disappears from the game crate — that's the GODVERSE magic, direction: real→game). In-game buys stay session-local per Option A. Assert both directions of the sandbox: a real gone item never renders; a game buy never appears in any server state (there's no verb to carry it — prove the absence).
5. The v5 tour + money shot (F). docs/shots/release_v5/: the crate walk — Musgrave Road → Monster Robot Party's frontage (B's mark visible) → the riffle with real covers → the price sticker → the buy. Plus one mint-shop frame (the honest caption: plausible, not real) and the ?classic=1 control. The R21 cluster-pose primitive poses the street frames.
6. Docs freeze (all lanes, light). A: CITY_SPEC v5 section (the tier ladder, sourcing, the id-space fences, the manifest) + charter risk-list retired-or-carried, v4-style. E: provenance v5-final (mint atlases + the licence line's story). C: LANE_C_PUB v5-frozen marker. G: the G3 doc updated design→as-built. B/D: notes current; nothing else owed.
7. The tag + the retro. F: qa.sh --strict --matrix + the kill-the-server gate green → tag v5.0 → push. Then Fable writes the epoch retro (not a lane deliverable), and the v6 conversation opens with John (the editor and multiplayer are still chartered; the GODVERSE has more rungs — Option B's reservation upgrade is already chartered as v5.x).

Laws

Charter v5 laws, all now with case law behind them · the vacuous-gate law · the id-namespace fences (sku_/mint_, plan-id/godverse-id) · no golden moves expected this round (tier 2 touches no plan, no cache, no atlas bytes) · the offline law is THE gate this round, not a footnote.

WAVE-2 STATUS + F'S THREE LOAD-BEARING INPUTS (Fable, post-wave review)

A/B/C/E/G are ALL IN. The beta tagged. What remains is F's close (#2 reader → #3 gate → #4 sandbox → #5 tour → #7 tag). The waves handed F three inputs that change the brief's letter — build to THESE, not to my original wording:

1. C's seam ruling (§8): direct wire, no hook — but PICK-THEN-OMIT is law. The naive wiring (filter pack.items) RESHUFFLES the crate — C measured one sale changing 21 other records. The reader draws from the stable full list and omits gone after: a crate with 3 sold shows 13, not a different 16. Assert zero collateral in the gate (sell one fixture record, the other 119 identities unchanged). "Selling one record must remove one record, not re-stock the shop."
2. G's finding: gone[] has no subject in production. The real POS has recorded no sale since 2026-07-01 — 0 of crate 550's 120 records have ever sold, so a sold-means-gone assert on live data passes vacuously forever. G built the remedy: make-fixture gives the gate a subject. The gate MUST use it (vacuous-gate law — G flagged it before the gate could be born blind).
3. G's lifecycle is the kill switch: godverse_server.py start|stop|status — the kill-the-server gate drives it directly. The three fences are machine-enforced (read-only credential measured permission-denied; /reserve+/buy → 501; metadata only, mint shops 404) — assert on them as fences, not re-derive them.

Also for the record: E's freeze caught redhill_godverse missing from the towns roster for three rounds (on disk, pinned, bootable by key — invisible only in B's selector; the one consumer nobody gated). E owned it, fixed it, and wrote the gate-shape lesson. B verified the R26 handshake against G's real manifest. A judged the risk list line-by-line and correctly CARRIED risk #1 — "nothing retires this line except that gate going green."

WAVE-3 STATUS + TWO RATIFICATIONS (Fable, post-reader review)

F's reader is IN (39cfc3d): pick-then-omit with gone/price applied IN PLACE (identity and order preserved), fire-and-forget with a 1200 ms abort + circuit breaker, real-sourced shops only. Browser-proven: 3 fixture sales → 0 collateral; server killed mid-session → 13.1 ms enter, 14 ms worst frame gap, zero errors. Two F rulings are hereby RATIFIED as law:

1. Tier 2 is opt-in: ?live=1 / ?live=<url>; absent → byte-identical to the beta. F's reasoning is the R26 lesson applied to a server — a default boot must never ask a question that has no answer on machines that aren't John's. "Tier 2 is a place you go, not a thing that happens to you." Auto-discovery is a v5.x question with a reachability contract.
2. The collateral assertion is the canonical sold-means-gone gate. "The gone item never renders" cannot discriminate pick-then-omit from filter-the-array — both hide the record; only COLLATERAL (the other 119 identities and order unchanged) tells them apart. Gates assert collateral. (The vacuous-gate law's most precise application yet.)

F's remaining close, in order: formalize the browser proofs as the permanent smoke class (#3's three arms + #4's both-directions sandbox, collateral-asserted, fixture-subject via make-fixture) → the v5 tour (#5 — the crate walk, the mint-shop honest caption, the classic control) → docs (#6 F-side: README v5 + the flags table gains ?live) → qa.sh --strict --matrix + the new smoke class → tag v5.0 → push. Then Fable writes the epoch retro.

WAVE-4 (Fable): two ratifications, one micro-task, and the tag path

RATIFIED — F's §27 console-error ruling, and it is strictly stronger than the brief it replaces. The brief's "ZERO console errors on server death" (my wording, echoed in A's risk line #1) is physically unachievable: a dead-host fetch logs ERR_CONNECTION_REFUSED at the browser level where no .catch() reaches — to log zero, the reader would have to know the server is dead without asking. One refusal is the irreducible cost of discovering death. The ratified assertion: zero errors from game code + EXACTLY ONE refused connection — which proves the circuit breaker, where "zero" could never distinguish a working breaker from a broken one (both fail it). F filed this loudly as the beneficiary instead of relaxing it quietly; that is the standard. (A: your risk-line wording is superseded by this record — a one-line amendment at your leisure, not a blocker.)

RATIFIED — the control-based frame assertion. F's original <250 ms threshold passed while measuring Lane C's room build and calling it network behaviour; the control (same walk, breaker tripped, no network: 202 ms) exposed it, and the death's true cost is Δ+2 ms. Assertions on frame cost are DELTAS AGAINST A CONTROL from here on, not absolute numbers — the R21 lesson, now law for performance gates.

THE MICRO-TASK — B: the frontage pose (F's filed ask). F produced three frames of empty road trying to re-derive your frontage anchor, then stopped — correctly (the cluster primitive answers "where is the town's heart", and Red Hill's heart doesn't contain Monster Robot; a frontage frame asks a different question). You own the frontage geometry, the R26 shopfront mark, and the poseForVenue machinery: publish a pose helper or bookmark that frames a shop's frontage BY LOT (keyed off shop.lot / godverseShopId — poseForShopFront(shopOrId, dist)), verified on Monster Robot (mark visible, door centred, sleeves-through-glass a bonus). One commit, B-pathspec. This also closes the gap for every future godverse tour frame.

Then F closes: the 4th frame through B's helper → full qa.sh --strict --matrix + the (now-permanent, corrected) kill-the-server smoke class → tag v5.0 → push. Fable's retro follows.

WAVE-5 (Fable): THE SPEC RULING — the facade is +Z, and the fifth hold stands

B's micro-task found why F photographed empty road three times: it was never the pose. plan_osm.js:443 aims the lot's −Z at the road (implementing CITY_SPEC:71); buildings.js:404 draws the facade on +Z (CITY_SPEC:335, B's canon). The spec contradicts itself; each generator implemented one half; synthetic follows B's canon so every golden has been green over a wrong product since R18 — v4.0 shipped on it. The epoch's signature species at its worst: not a gate failing on correct behaviour, but a green suite over a wrong world.

THE RULING: the visible facade is LOCAL +Z. B's canon is canonical. It has been the de facto truth since v1 (buildings.js drew it there from the start; venue.js seats door-glow/ queue/posters there; A's own R15 write-up said "the visible venue face is +Z"). CITY_SPEC:71's −Z line described the SIM convention (rig-forward at ry=0) and got written into the lots contract by ambiguity — the same −Z/+Z species as R13's RY_FLIP and R15's posters, now at the root. The spec amends so the lots contract states: facade/door/frontage = local +Z; the sim/rig-forward convention is documented separately as the different thing it is.

A — the fix, the sweep, the pins (ONE commit):

1. Land B's proven one-liner in the real-roads seating (ry = atan2(-nx,-nz) — B measured katoomba 0/72 → 72/72 facing and F's money shot works 4 m from Musgrave Road; B reverted it because it's your file).
2. Measure the marched-osm path for the same flaw — don't assume it's clean because nobody noticed; that's how this one survived nine rounds. State the verdict either way.
3. Amend CITY_SPEC:71 per the ruling, re-pin every moved golden (the 36 real-town pins move; marched/synthetic only if your measurement says so), all in the same commit per the amendment law.
4. The cross-convention gate (the lesson made law): the selfcheck gains an assert measured in B's canon — every lot's +Z facade faces its frontEdge street side — so the two conventions are compared AGAINST EACH OTHER forever, not each against its own spec line. A self-consistent check over a self-contradicting spec passes under either convention; only the cross-check sees it. (F proved this the hard way and recorded it.)

F — then the close: re-gate (the matrix against A's re-pins), re-shoot the tour (the frontage frame through B's poseForShopFront — and street_noon on real towns, which has been "46 draws of bare road" since R18, becomes a real street), qa.sh --strict --matrix, tag v5.0, push.

B — done, with honours: the helper (door-centred by projection, doorCentreNdcX = 0.0000), the selector extracted to ONE home ('g:31' — the id-namespace fence now has a single resolver), the self-correction of your own R27 intel, and the discipline of proving A's fix then reverting it. Nothing further owed.

THE EXACT RUN ORDER

0. WAVE 0: F re-runs and tags v5.0-beta. Hard stop until it lands.
1. Start together: G (#1 endpoints, on ultra) + C (#2 seam ruling: publish the hook or bless the direct wire) + A/E (#6 docs prep — can run the whole round).
2. When G's endpoints are live on the tailnet and C's seam is ruled: F (#2 reader).
3. F (#3 kill-the-server gate + #4 sandbox proofs + #5 tour), then #7: tag v5.0, push.
4. Fable: the epoch retro.

Waves: [F-beta-tag] → [G, C, A+E] → [F reader] → [F gate/tour/tag] → [retro]. B/D on-call.

Standing

• John — one infra FYI, nothing to decide: the kill-the-server gate needs the thriftgod server reachable from m3 over the tailnet AND stop/start control from the gate (G owns the mechanism — a lifecycle endpoint or an ssh'd systemd unit, G's call; it's in-house infra under existing access). Your A-then-B ruling continues to hold the write verbs absent.
• v5.x / v6 preview (the retro decides, do not start): Option B's reservation upgrade (behind your hold budget) · more POS shops if monsterrobot ever gets siblings · the editor · multiplayer presence · the v4.x/v5.x polish tails.
