"""PROCITY Lane F — the town-matrix smoke (round 17, v3.2 · the real-map scout gate · ledger #7).

The gate side of the scout: run the core smokes across the FULL town matrix — synthetic hero seeds, the
three checked-in osm fixtures, and Lane E's real AU town caches — and emit one town × gate table. This is
the evidence John charters v4 (THE REAL MAP) on: proof the existing CityPlan contract eats real geography
through the default boot, with no new game systems.

Gates per town (all on the DEFAULT boot — gigs/weather/winmap/tram on, post-R16 flip):
  • boot        — the plan builds + the shell reaches window.PROCITY.plan, 0 console errors
  • determ      — two fresh in-page generations are byte-equal (the generator is deterministic)
  • budget      — the busiest default view (venue block at night) ≤ 300 draws / 200k tris
  • district    — the gig layer placed on this town: ≥1 venue, a week schedule, posters
  • noassets    — ?noassets=1 boots silent (0 errors, 0 network); real caches fall back to a fixture (correct)

Run:  tools/.venv/bin/python tools/qa/town_matrix.py
Needs the Playwright venv + Lane B's ?dbg=1 hook + Lane F's real-cache shell wiring (R17).
