Form A Day-3 shipped at lumbda ecfe27a. Windowed-G ladder (w=4,
16-entry G-table built once via batch-inverse on the 15 Z-coords)
landed clean.
Bench on 3090, n=1M (best-of-3, --no-batch-inv):
v1 (Day-1) 127.04 ms → 7.87 Mkeys/s
v3 (Day-3 w=4) 73.54 ms → 13.60 Mkeys/s (1.73x v1, ~309x coincurve)
Byte-identity PASS at n in {32, 1000, 10000, 100000, 1000000} plus
known-small edge cases (k in {1, 2, 3, 7, 0xdeadbeef, n-1, n, 2^128-1}).
Daemon default still serves v1; --window-w 4 flag selects v3
explicitly. Fox's call on flipping the daemon default.
Day-4 plan: stack v3 + Day-2 batch-inv. v3 cut scalar_mul; the
residual inversion cost now actually matters, which is what Day-2
needed to win.
Three agents still in flight: walker promotion (#39), lever
generator (#40), ai.foxhop.net second worker (#30).
