cdb on the PDB-paired retail client during the user's 45-degree glide:
edge_slide/cliff_slide 594 each in lockstep, set_sliding_normal 538,
step_up ZERO. Ours: 18 edge-family firings total, stuck ticks
dead-looping on insert retries. The divergent branch is
transitional_insert's handling of the refused steep walkable — retail
proceeds into the step-down-failed/edge path per tick, we retry from
scratch. The D0 code-reading's 'retries from scratch, retail-identical'
conclusion is corrected by the runtime evidence: the profile is what
the decomp reading could not see.
