a493c0a13c Lane A round 25 (v5.0-alpha): the sweep reconciled with Ruling 2 + the six pins (ledger #1)
All 8 tree reds cleared. selfcheck ALL GREEN 156,211/156,211; scaffold + consistency green; classic
0x3fa36874 and gig 0xb1d48ea1 frozen. F: the tag is unblocked from my side, nothing of mine is pending.

SIX OF THE EIGHT REDS WERE MY OWN GATE ASSERTING RULING 2 AWAY. I built the R24 identity arm on an
assumption that was true when I wrote it and false the moment G shipped: that a godverse cache is ALL
census shops. Ruling 2 makes it MIXED -- a keyed GODVERSE layer plus an inherited OSM texture layer that
G measured to be load-bearing, not cosmetic (census-only Red Hill: 306 m spacing warn + a poster inside a
kerb). So newtown_godverse (18 keyed + 54 texture) and redhill_godverse (10 + 27) were HEALTHY TOWNS MY
GATE CALLED BROKEN -- it fired 54/72 on a good town. Keyed asserts now run PER-LAYER over the keyed subset
only; unkeyed texture shops raise nothing. The validator's "N/M missing" warn dies with it. The one honest
requirement left at that layer: a `godverse+osm` cache must have a NON-EMPTY godverse layer (else it's an
osm cache wearing the wrong `source`) -- still a warn, for the R24 charter reasons that still hold.

THE UNIQUENESS CHECK WAS BROKEN IN BOTH DIRECTIONS. `new Set(all ids).size === shops.length` collapses
every `undefined` into ONE Set entry, so it (a) failed structurally on any mixed cache -- 54 texture shops
became one entry -- and (b) could HIDE A REAL DUPLICATE behind that same collapse. Now over DEFINED ids
only. And per the vacuous-gate law I made it prove it bites rather than asserting that it does:
validateTownCache rejects duplicates at the front door, so a dup can never reach the plan that way -- the
test feeds one STRAIGHT TO THE LIFT (generatePlanOSM does not validate) and asserts the predicate catches
it, with a healthy mixed cache passing the same predicate. A check nobody can watch fail is not a check.

NEW -- THE ORPHANED-ATLAS GATE (my own R24 finding, now enforced instead of filed). The lift legitimately
drops shops (overlap-resolve, counted since R19). Dropping a shop that HAS a committed atlas means real
stock keyed to a shop that isn't in the town -- exactly the failure I filed in R24, and one F's #7b could
only catch in a browser at the end of a round. Now a node gate: for each godverse town, every
stock_godverse/<id>/ on disk belonging to that cache MUST be seated, else FAIL. Subject-aware -- it SKIPs
by name when a town has no atlas, rather than passing quietly.

It already found one, benign today: redhill's lift drops keyed shop 2286 "Empire Revival" (10 keyed in
cache -> 9 seated). No atlas, so nothing is orphaned and the gate passes -- but it prints, because a drop
must never be silent (the R19/R20 ruling). G: stocking Empire Revival at the beta would orphan it. Monster
Robot Party is seated (lot 8), which is the one that matters this round.

THE SIX PINS, cross-checked two ways before landing -- byte-identical across two fresh processes, AND
matching the three values G stated independently in 86e2985:
  newtown_godverse  base 0xcf69b387  gig 0x1e266f60   (moved by G's keyed re-emit)
  redhill_real      base 0x6046700f  gig 0x673785ee
  redhill_godverse  base 0xb2224939  gig 0xc6f80e18
No other golden moved -- the diff is exactly these six lines.

Two lines still print; both deliberate, neither pending:
  ⊘ SKIP newtown_godverse orphaned-atlas -- correct, the only committed atlas (3962749) keys to Red Hill.
  ⚠ redhill_godverse: 1 keyed shop dropped -- the honest disclosure above.

Committed strictly by pathspec: F's six staged files sit untouched, exactly as its session left them.

1eb0b45bd0 Lane A round 24 (v5.0-alpha): the identity field — godverseShopId, published first (ledger #2)
The optional shop key that resolves `stock_godverse/<godverseShopId>/`. Schema STAYS v2 (optional field ⇒
every shipped cache still valid, the 21 osm caches untouched by construction). Published to
web/assets/towns/README.md — the doc G and E build to — plus CITY_SPEC. selfcheck ALL GREEN (+15 checks),
synthetic 0x3fa36874 frozen, NO golden moved.

THE BRIEF'S "THE POS SHOP ID IS THE ID — NO MAPPING TABLE" IS FALSE FOR THE ONE SHOP THIS ALPHA IS ABOUT.
G's own docstring says it: Monster Robot Party is NOT in thriftgod's census, so its id is its DEALGOD STORE
ID 3962749, while census shops use thriftgod ids (max 2992) -- two disjoint spaces, deliberately kept clear
of each other. Had I coded "godverseShopId == shop.id" or derived it from the census, the headline shop
could never be keyed. So it is an OPAQUE key: no derivation from `id`, no equality assert, no mapping table
(the R12 gigKey law -- one key, zero mapping; G emits, everyone reads).

THE FIELD HAD TO SURVIVE THE LIFT OR IT WAS DECORATION. plan_osm builds a FRESH shop object and copies
nothing unknown, and the runtime reads plan.shops[], never the cache -- so a cache-only field could never
reach F's per-shop base. It's now carried through, CONDITIONALLY: absent ⇒ the key isn't written ⇒
JSON.stringify byte-identical ⇒ every pinned golden holds until G re-emits (that re-emit IS the sanctioned
move). Proven end-to-end: a keyed cache puts `stock_godverse/3962749/` on the plan with census ids
(101..107) coexisting alongside it.

ARMS SPLIT BY HAZARD, NOT TIDINESS:
- malformed  -> ERROR. It names a path segment; "3962749" vs 3962749 is the same folder but different JSON,
  and that coercion drift is the exact species that broke C's atlas contract (licence/license).
- duplicate  -> ERROR. Two shops keyed to one atlas IS mis-stocking -- charter risk #3 forbids it by name.
- missing on a godverse cache -> WARN + fail-soft to tier 0.

RECORDED DEPARTURE (Fable's to overrule): ledger #2 says validateTownCache "requires" the field; I made
MISSING a warn. Three reasons. (1) The charter's determinism boundary is "world = seeded, frozen, gated;
stock = data tiers" -- an error inverts it, failing to load a TOWN because its STOCK identity is absent;
tier 0 must always boot. (2) Charter risk #3 names the remedy for identity gaps: "fail-soft to tier 0,
never mis-stocked" -- missing IS the soft case, duplicate is the hard one; they are different failures and
now get different arms. (3) Sequencing: newtown_godverse carries 0 ids today, it is G's to re-emit in wave
2 (their namespace, no census DB on m3), so a hard error would red the tree for C and E through all of wave
1 to say what the warn already says.
The requirement keeps its teeth where R23 taught us to put them -- the VACUOUS-GATE LAW: selfcheck FAILS on
partial keying (a half-keyed town silently mis-stocks the rest) and prints an explicit
"⊘ SKIP ... 0/18 shops carry godverseShopId. Subject absent ... binds the moment one id lands" at zero. It
names its subject, proves it touched it with a count, and cannot pass vacuously.

FILED FOR G BEFORE THEY START (measured in wave 1, so it costs them minutes not a wave): redhill_godverse
cannot contain Monster Robot from EITHER source. godverse_town.py takes roads from the OSM donor and shops
from the census, and the shop is in neither -- not in the census (G's R23 finding), and NOT in E's
redhill_real, which I checked the moment it landed: 36 shops, ZERO of type `record`, nothing matching
/monster|robot/. As written the adapter yields a Red Hill of census charity shops while the atlas keys to a
shop that isn't in the town -- F's #7b id-equality gate would fail at the end of the round. It must be
injected explicitly; the opaque-key design exists precisely to serve that case. Second trap on the same
path: redhill_godverse must still clear MIN_TOWN_SHOPS (6) from the census bbox or the cache is rejected
outright (hard error). E's donor is otherwise good: valid, no warns, 73.3 m median spacing.

HOUSEKEEPING: removed toowoomba's two stale pins -- E retired the cache in R23, and a golden for a town
that cannot load can never fire (the vacuous-gate law, one layer down). E's attempt also proved my R23
spacing metric is GAMEABLE: the re-bbox fixed the median (395.7 -> 89.4 m, "passes") while hub density fell
3/12 -> 2/12, the pack's worst. It is necessary, not sufficient -- D's hub test is the complement, and E
used both and refused to game it. Ballarat (255 m) is still flagged and still E's call; I pin what moves.

PINS NOT TAKEN YET, DELIBERATELY: redhill_real is untracked/in-flight (E still editing build_towns.py), and
redhill_godverse + the re-keyed newtown_godverse don't exist until wave 2. Pinning a moving file buys a
false green or a spurious red. The round's law says A pins these BATCHED -- that batch lands when E commits
and G's caches are in.

292b07aa91 Lane A round 23 (v5.0-alpha): the spacing warn — D's thin-tail finding as law (ledger #5)
validateTownCache now warns when medianShopSpacing(cache) > MAX_MEDIAN_SPACING_M (150 m). Metric +
threshold exported from the barrel so no lane re-derives them. WARN, NEVER ERROR: a flagged cache still
boots a valid district (toowoomba shipped green through the entire v4.0 pack) — E curates, A flags.
selfcheck ALL GREEN 161,372/161,372 (+72); synthetic 0x3fa36874 frozen; NO golden moved (only E's
toowoomba re-bbox may move one this round, per the round's law).

THE THRESHOLD IS MEASURED, NOT PICKED. The brief offered darwin 27 m / toowoomba 388 m as "plenty of
daylight for a line" — but that's 2 points. Measuring all 23 towns shows a near-continuum, and the line
is FORCED into (119.3, 254.9]: braddon at 119.3 m is ALIVE by D's own hub test (7 shops within 160 m,
identical to darwin's 7), ballarat at 254.9 m is not. 150 m sits in the pack's widest gap (x2.14), with
1.26x margin below and 1.70x above. Flags 2 of 23.

TWO TOWNS FLAG, NOT ONE. The brief names only toowoomba (D spot-checked the two 12-shop towns). The
measurement adds BALLARAT at 255 m — nobody has looked at it, and it's independently one of the three
towns my R22 graded cluster fallback fired on (no venue candidate at the >=3-shops/160 m floor). Two
signals agree. Filed for E as a curation call, counted either way.

THE BRIEF'S ANCHORS WERE IN THE WRONG SPACE, AND IT MATTERS. D's 27 m is PLAN space (post-lift metres);
validateTownCache is CACHE space (raw lat/lon — the only thing that exists at ingest, and the layer where
a bad bbox must be caught). Darwin is 68.3 m in cache space, not 27. Interpolating a threshold between
D's figures would have silently mixed spaces. I verified the hypothesis before trusting it: computing the
metric plan-side reproduces D's numbers exactly (darwin 27.2 vs 27, toowoomba 386.8 vs 388, hubs 7 and 3).

Cache space is correct HERE and provably safe: the lift marches shops at a regularised cadence, so it
COMPRESSES dense towns (darwin plan/cache 0.40) but not sparse ones (toowoomba 0.98, ballarat 1.01) --
the error lives at the dense end, the warn only fires at the sparse end. Verified all 23 towns in both
spaces: exactly ONE disagrees, newtown_godverse (94.4 cache passes / 158.3 plan would warn). Filed for
G/Fable, NOT acted on: no cache-space line catches it without false-positiving braddon, and godverse is a
census subset (18 thriftgod shops over the footprint that carries 72 OSM shops) so its sparsity is
coverage, not a bad bbox — re-bboxing, the warn's only remedy, cannot fix it. Worth knowing since R23
stocks the real crate in that town and the beta asks "fitzroy_godverse if the census is dense there".

Also fixed en route: the R17 silent-fallback trap bit again in my own scratch harness — an unregistered
town key resolves to the melbourne fixture rather than erroring, so five towns silently measured
identical. Registered the caches; noting it because it has now cost two rounds.

Coverage: sparse cache warns + still boots (structural + district suites on a flagged town), compact
cache does NOT warn (no false positive), metric edge cases (< 2 shops -> null, coincident -> 0, no throw
on empty), and an exact-value check (a 100 m pair measures 100 m, projection sane).
Cost: ~1 ms/town at registration (25.6 ms for all 23 incl. fitzroy's 160 shops) vs a <100 ms plan budget.

E -> use the warn as your acceptance test for #4: re-bbox, re-run, warn goes silent = the town has a high
street. If your fix moves toowoomba's or ballarat's cache, ping me — goldens are mine to re-pin, and only
what you move.

5d29863b78 Lane A round 20: absorb E's density widening — capacity, pub facade bias, goldens pinned (ledger #2)
E's five caches landed at 3-6x shops (292 total: katoomba 20→80, fremantle 21→80, newtown 18→72,
bendigo 9→36, castlemaine 6→24). All five absorb cleanly and still place 3 venues; the R20 poster cap
auto-scaled off the live shop count exactly as designed (katoomba 111 posters at 80 shops).

- CAPACITY WIDENED (the R18 overflow fence, load-tested). At 4x the dominant drop cause was OVERFLOW —
  an edge-side holding more shops than fit (katoomba 10 of 11 drops). Tightened the run: NODE_CLEAR 6→3
  and a ROADS-ONLY RGAP 2→0.5 (the shared marched GAP is untouched ⇒ marched fixtures stay frozen).
  Drops 7.9% → 5.5% (16/292). 0.5m also reads truer — a real AU main street is continuous terrace
  shopfronts, not detached boxes. Stopped there deliberately: the next lever (spilling overflow onto a
  DIFFERENT street) buys ~1% by putting a shop on a road it isn't on — dropping a crowded shop is the
  honest trade. Residual drops stay COUNTED, now BY CAUSE (dropped_overflow/_overlap/_stranded).
- VENUE FACADE BIAS NOW COVERS pub. R16 exempted pub ('spine-fronted, +Z always open') — true on the
  synthetic/marched towns, but on a REAL graph at density the pub landed where its frontage poster
  overhung a cross street (newtown, -0.91m). The POSTER_CLEAR filter now covers every venue kind; still a
  NO-OP on synthetic (every pub candidate already clears) ⇒ gig golden 0xb1d48ea1 frozen.
- Goldens re-pinned ONCE (base + gig, all five towns). classic 0x3fa36874 / gig 0xb1d48ea1 / marched
  fixtures FROZEN. selfcheck ALL GREEN 51866/51866; scaffold + consistency GREEN; cross-process
  deterministic.
- Fixed: my real-cache loader globbed *.json and tried to validate E's new index.json as a town cache —
  it now skips it (that's B's selector index, not a cache).

Handshake → all: densities absorbed, goldens pinned. → F: re-measure venue_night + gate the five towns.

6fc4b40632 Lane A round 19: the v4.0-alpha close — fragmentation ruling + findings hardened + goldens pinned
A's finalization (ledger #1), the round's spine. Every filed R18/R19 finding resolved; the tag is F's.

- Fragmentation (D's finding; Fable ruled, A owns details). The naive real graph fragmented (katoomba 105
  components, 58% street-metres on islands). plan_osm.buildRealRoads now: (a) JUNCTION-PROTECTED
  Douglas-Peucker — a point shared by >=2 ways is a junction; simplify only BETWEEN junctions, never
  through one (the collinear tee-off drop, the root cause) → 94-100% main-net alone; (b) cull/bridge —
  main component + near-fragments joined (JOIN_TOL 12m; shop-island bridge <=200m), far SHOPLESS islands
  culled. Result: 1 connected component on all 5 towns (katoomba 100% main-net, 2 islands culled). Every
  dropped shop COUNTED in norm.dropped (ruling): katoomba 19/20 (1 crowd drop — R18 overflow prediction
  measured), the other four kept all.
- E's poster-clearance finding fixed (gigs.js): a spine poster overhanging a real crossing carriageway is
  skipped, measured exactly as the selfcheck kerb floor — a NO-OP on synthetic (gig golden frozen, pr()
  consumed before the check). 23 real-town clearance failures → 0.
- Goldens pinned (A->E->A finalization): all 5 real towns on their real-roads output (katoomba 0xb7ffbca2,
  newtown 0x6f984c81, fremantle 0xfb197000, bendigo 0x21179b3b, castlemaine 0x7c47f639). synthetic
  0x3fa36874 / gig 0xb1d48ea1 / marched fixtures / classic / default FROZEN — the alpha changed nothing
  outside the cache-schema path. selfcheck ALL GREEN 51670/51670; scaffold + consistency GREEN. Cross-
  process deterministic.
- New finding filed (beta, non-blocking): spine-poster density scales with edges (katoomba 438 vs ~14
  synthetic; draws low via instancing) → a beta posters-per-town cap.

Handshake fired → B/C/D/F: katoomba_real boots real roads, golden pinned, findings resolved.

a78dc76f84 Lane A round 18: the real-graph lift — OSM ways → CityPlan street graph (v4.0-alpha REAL ROADS)
The epoch headline (ledger #2). A v2 cache's roads[] now builds the CityPlan street graph FROM real
OSM geometry instead of marching shops onto synthetic avenues. SAME CityPlan schema out — B/C/D/F consume
it unchanged by contract. roads absent ⇒ the v1 marched fallback, so classic/gig/osm goldens are FROZEN.

plan_osm.buildRealRoads: project ways+shops to the local metre frame → simplify each way (Douglas-Peucker
eps~6m, the fidelity knob) → snap coincident points (<=3m) to shared nodes = real intersections →
straight-segment edges → classify main by OSM highway class + shop density → seat each shop on its NEAREST
real edge (real order, real side), marched with regularised spacing + a deterministic overlap-resolve pass.

Fidelity (charter risk #4): real edge/order/side + regularised spacing — NOT pixel positions (real shops
overlap; the no-overlap invariant is load-bearing). Alpha failure list in LANE_A_NOTES §R18: overflow drop
on short edges; intersections = shared-coordinates only (a D sim-graph risk); per-edge frontage-strip
blocks not planar faces (a B ground-render item); crowded-intersection overlap-resolve.

Proven: a committed synthetic irregular graph (main + two cross streets + a real intersection + an acute
angle + a dead-end lane + a curve) passes the FULL structuralSuite + gig district + byte-identical
determinism; mutation-tested non-vacuous (flip the facade facing → 'faces its frontEdge' fails). Robust on
messy inputs (single road, coincident dups, disconnected ways, all-roads-too-short → marched). All osm
goldens frozen; E's 4 trailing caches pinned on v1; katoomba_real UNPINNED (its real-roads golden pins when
E lands roads — the A->E->A finalization). selfcheck ALL GREEN 16810/16810; scaffold + consistency GREEN.

4dc80c2146 Lane A round 18: town-cache schema v2 (roads[]) — published FIRST (v4.0-alpha REAL ROADS)
The half-day handshake so E's build_towns.py can fetch road geometry (ledger #1). Optional roads[]
on the town cache carries real OSM way geometry; plan_osm's graph lift (consuming it) follows in the
next commit. v1 caches (roads absent) stay valid — the marched fallback — so nothing shipped regresses.

- validateTownCache accepts schema procity-town-cache/1 AND /2; when roads[] is present each road must be
  { kind:string, pts:[[lat,lon],…] } with >=2 finite points (else rejected); <2 pts dropped, unmapped
  highway kind → 'side' (warnings). ROAD_KIND maps OSM highway=* → CityPlan edge kind (main/side/lane/arcade).
- Full v2 contract in web/assets/towns/README.md (the doc E builds to): shape, road validity, the kind map,
  the fidelity knob (charter risk #4), and the bbox-bound-the-roads rule.
- E's 5 existing v1 caches re-validate clean; selfcheck ALL GREEN.

6fffd19043 Lane A round 17: v3.2 the town-cache contract (published first) + plan_osm hardened for real data
The real-map scout (ledger #6), A's half. Scope fence held: NO new plan features, NO golden moved
(classic 0x3fa36874, gig 0xb1d48ea1, all three osm fixtures frozen). The scout proves the EXISTING
?plansrc=osm contract eats real geography.

- The town-cache contract (published FIRST — E builds build_towns.py to it). plan_osm.js gains
  validateTownCache() (authoritative {ok,errors,warnings}), registerTownCache(), a generatePlanOSM(..,
  {cache}) seam, and TOWN_CACHE_SCHEMA/MIN_TOWN_SHOPS(6)/MAX_TOWN_SPAN_M(5km). Shape: {schema,key,town,
  source,license,attribution,center{lat,lon},shops[{id,name,type,lat,lon,suburb?}]}. Home declared:
  web/assets/towns/<key>.json (+ README.md full spec). Documented in CITY_SPEC v3.2 + LANE_A_NOTES R17.
- plan_osm hardened: blank name -> registry label; the validator gates finite center/coords + a >=6-shop
  floor and warns on unknown-type(->opshop)/dup-id/span>5km. Proven vs thriftgod's real 2,828-shop
  city_source.json: boots a valid plan, 0 bad coords, 0 'undefined' names.
- selfcheck: a committed synthetic-adversarial contract suite (valid-messy caches boot + pass structural/
  gig; invalid reject; wide-spread warns; registry seam) + an auto-loader for web/assets/towns/*.json
  (validate -> suites -> pin per-town golden), empty and green until E lands caches. ALL GREEN 15277/15277.
- v4 charter risk list (LANE_A_NOTES R17): the MEGA-STRIP (unbounded bbox -> 11.6 km strip; town selection
  is E's real lever, warned >5km); sparse compact towns (2 km inner-Canberra held 6 shops); osm facades
  clear (rows 54 m apart) so R16's bias is a no-op on real towns.

E->A handshake: E drops a cache in web/assets/towns/, the selfcheck prints its golden, I pin it.

f952f513d0 Lane A round 8: OSM to parity + a second town (Katoomba) — carried R7 brief, full
The carried brief (slipped R7) lands complete — all four items, qa.sh --strict GREEN.

1. Selfcheck PARITY: extracted structuralSuite(plan,label) and run the FULL invariant suite
   on every (source, town) — synthetic + both OSM towns get identical coverage (storeys,
   one-shop-per-lot, facing, within/cross-block overlap, corridor coverage, determinism,
   exactly-one-openLate). ALL GREEN 1727/1727 (was 1362; OSM went subset → full ×2 towns).
2. SECOND TOWN: Katoomba (Blue Mountains, 19 shops, op-shop/book heavy) — regional contrast
   to inner-Melbourne. osm_fixture.js → OSM_TOWNS{melbourne,katoomba}+DEFAULT_TOWN;
   generatePlanFor(seed, source, {town}); ?plansrc=osm&town=katoomba. Golden 0x0f652510.
   Melbourne 0x34cfdec0 + synthetic 0x3fa36874 UNCHANGED (town key kept off the plan).
3. "Add a town" recipe in LANE_A_NOTES (R8): extract → OSM_TOWNS → pin golden → tell F.
4. Normalization + LOG: importer bends real data to the contracts (unknown kind→opshop,
   hours-clamp so only one shop is openLate, video-preferred landmark w/ fallback) and logs
   it via {report}; selfcheck prints per-town (e.g. melbourne hoursClamped:5, openLate:video).

For F: three goldens to pin, gate keyed (seed, plansrc, town); selector gained {town} — see
LANE_A_NOTES R8. Screenshots docs/shots/laneA/osm-{melbourne,katoomba}.png.

52eb1090ef Lane A round 6: second plan source ?plansrc=osm (real-data OSM import) — full seam
The carried-over OSM plan source (no-showed R4–R5) lands complete, invariants green — a
second CityPlan producer behind the same contract, so B–F consume it unchanged.

- osm_fixture.js: 95 REAL inner-Melbourne secondhand/charity/music/book/toy/antique shops,
  extracted deterministically from thriftgod city_source.json (Overpass cache), imported as a
  module ⇒ ZERO network.
- plan_osm.js: generatePlanOSM(seed) — project lat/lon→metres, bin shops into latitude-band
  avenues off a spine (real row + real E–W order preserved), march into a valid non-overlapping
  CityPlan, centre on origin, report true 362×486 bbox, real shop names, one openLate video.
- index.js: generatePlanFor(seed, source) selector — default 'synthetic' BYTE-IDENTICAL
  (golden 0x3fa36874 untouched); 'osm' → the importer. generatePlanOSM exported for F.
- selfcheck.js: parameterized by source — OSM runs the full structural invariant suite
  (frontEdge/facing/no-overlap/chunk-coverage/finite/JSON/determinism/openLate) + its own
  golden 0x34cfdec0; synthetic-only brief checks skipped. ALL GREEN 1362/1362.
- map.html: ?plansrc=osm renders it (reference wiring for F). Screenshot in docs/shots/laneA/.
- CITY_SPEC: plan-source note; LANE_A_NOTES R6: seam + goldens + shape-diffs for F's gate (F2).

Honest cut: street geometry regularized (real row+order drive it, exact metres do not);
name-parody deferred. qa.sh --strict GREEN.
