The closing half of F's bookend. All gates green on the flipped tree (qa.sh --strict --soak: classic
regression + default-boot gate + smokes + no-giants incl. the seated drummer + the full-week soak).
- tour_shots.py -> docs/shots/release_v3_1/: the money shots on the DEFAULT boot (no per-shot flag juggling
now the flip covers it) + a ?classic=1 before/after ("the town before v3"). 7 shots, settled, 0 page errors.
- week_soak.py: re-pointed to the default boot; the leak check now treats an at/below-baseline OR non-climbing
trail as leak-free (a decreasing tex trail is GC/atlas-settle, not a leak — it was false-failing at warn-level).
- docs: README v3.1 flags table (defaults on + ?classic=1), CITY_SPEC v3.1 amendment (the rewritten prime
law + classic covenant, A's deferred edit), LANE_F_NOTES §16, F-progress R16.
Numbers (seed 20261990): default @ venue block 124 draws / 57k tris (<=300/200k); ?classic 161 draws / 24k
tris (the v2 baseline); seated drummer 1.32 m stature; week soak 42 cycles leak-free (net +0/-6).
