Release round: harden + freeze, no new systems. No golden moved (synthetic 0x3fa36874, gig
0x1f636349 both re-verified frozen); selfcheck.js is the only code touched, so no seeded generation
stream gained a draw (release-round law).
- selfcheck.js: factored the district checks out of gigSuite into districtInvariants(plan,label)
(behaviour-preserving — hero-seed gigSuite runs byte-identical), then added a 400-seed synthetic
sweep + the large edge seeds asserting the full district contract each (2-4 venues, >=1 pub, never
the openLate shop, no band twice/night town-wide, per-venue 4-6 nights, every poster off the
carriageway). Asserts the seeded count spans {2,3,4} across 400 seeds (146/121/133 — range is
exercised, not pinned). osm graceful placement: katoomba (19 shops, no warehouse district) still
lands 2-4 valid venues incl. a pub for every hero seed. Poster check kept at roadWidth/2 (a literal
poleOffset compare would false-fail corner posters); added -1e-6 epsilon on the strict boundary.
ALL GREEN 14264/14264 in ~0.7s.
- CITY_SPEC §v3: final wording pass, marked FROZEN at v3.0 (round 14) with a v2-style marker + an
explicit carve-out for F's pending alias-line deletion. Fixed the roadWidth prose (full carriageway
width, not 'half-corridor'). Genres final (pubrock/grunge/covers).
Coordination: the R12 single-venue alias line stays in §v3 for F to delete atomically with the
gig_state.js getters (debt #1) — deleting now would be doc-ahead-of-code (alias still live) and race F.
Flagged to F that the runtime block omits nightOf(id); to B that venue.js:228 is a 2nd bare-string
site. Verified: mutation-tested the sweep (non-vacuous — catches 5-venue/7-night/on-road violations)
+ adversarial pass (goldens frozen, freeze matches code, deterministic).
