AP-7's gate is the Sledding branch; ACE's linear calc_friction (0.25 dot
threshold, unconditional small-angle subtraction, Sledding overrides) is
the correct reading and the L.3c walking regression is architecturally
moot for the root-motion path. TS-1's register cite is stale dead code -
the PrecipiceSlide/CliffSlide/EdgeSlide chain is substantially ported
with one precise back-probe re-cache gap. #166 is a composite of
AD-25+AP-7+TS-4, not a missing Sledding auto-toggle (no client write site
exists). TS-4 removal is sequenced AFTER the TS-1 gap closes with
captured fixtures. #116 stays oracle-first. Port order + 8 open
Ghidra-verify questions recorded.
