capture(research): A6.P1 scen2 — inn stairs paired traces
Walked +Acdream up 4 steps of Holtburg inn, stopped on landing,
shuffled briefly to push past 50K cdb threshold. Acdream walk
exceeded the minimal scenario script (user explored further) —
scen2 dataset is a superset of the protocol; A6.P2 analysis can
window to the comparable section.
Retail (decoded, 110,104 lines):
BP1 transitional_insert: 60,289 hits (~5x scen1)
BP2 step_up: 188 hits (vs scen1 = 1 — stair signal)
BP4 find_collisions: 47,783 hits (~8x scen1)
BP5 adjust_sphere: 780 hits (~65x scen1)
BP6 check_walkable: 677 hits threshold=0.6642 confirmed
BP7 set_contact_plane: 136 hits (~7x scen1)
Acdream (73,937 lines):
[cp-write]: 70,244 — CP-write blowup persists on stairs
[push-back-disp]: 1,141
[push-back]: 101
[push-back-cell]: 87
[indoor-bsp]: 343
[indoor-walkable]: 227
Note: cdb's qd-in-BP-action threshold doesn't actually self-detach
(documented CLAUDE.md cdb watchout) — user closed retail manually.
Three remaining workflow steps work cleanly (decode + acdream pair
+ graceful close).
