Erik ceeb06be7d ship(phys): A6.P3 slice 3 — cell-resolver ping-pong CLOSED + #98 re-diagnosed
Slice 3 v2 (3e140cf) added point-in cell-stickiness in
ResolveCellId's indoor branch. User verification + slice3v2 capture
confirms: cell-resolver ping-pong is FULLY CLOSED.

Data:
- scen2_v2 capture (pre-slice-3): 20+ cell-transit events with
  rampant ping-pong (0xA9B4014B ↔ 0xA9B4014A ↔ 0xA9B4013F at the
  cellar boundary, Z stable ~96.4 — same tick re-classification)
- slice3v2 capture (post-fix): 1 cell-transit event (login teleport
  only) — ping-pong fully eliminated

Findings:
- A6.P2 Finding 3 (cell-resolver sling-out family) CLOSED.
- Issue #90 (sphere-overlap stickiness workaround in same function)
  now redundant; can be removed in A6.P4 after broader visual
  verification.
- Issue #97 (phantom collisions + fall-through on 2nd floor) hypothesis
  pending: same instability family, likely closed as side-effect of
  this fix. Re-test on next happy-test session.
- Issue #98 (cellar-up stuck) PERSISTS but with NEW DIAGNOSIS.
  Originally filed as cell-resolver ping-pong (which was true and now
  fixed), but user verification shows the cellar-up symptom remains
  with a DIFFERENT root cause: BSP step-physics at the cellar stair
  TOP. Push-back trace from slice3v2 capture:
    n=(0, -0.719, 0.695) sloped face (walkable per FloorZ=0.664)
    delta=(0, 0, 0.75) step-down probe lifts sphere by 0.75m
    winterp=1.0->0.0 entire walk-interp consumed per tick
  Player progresses up most of the stairs but blocks at top step
  where the cellar transitions to the cottage main floor. #98 issue
  updated with this re-diagnosis.

Includes:
- scen4_cottage_cellar_slice3 acdream.log (slice 3 v1 evidence;
  ping-pong already closed by v1's sphere-overlap stickiness, but
  v1 over-corrected by holding player in cellar during legitimate
  transitions)
- scen4_cottage_cellar_slice3v2 acdream.log (slice 3 v2 evidence;
  point-in stickiness fixes the over-correction; cellar-up reveals
  the deeper BSP step-physics bug)

Docs updated:
- ISSUES.md — #98 re-diagnosed
- docs/plans/2026-04-11-roadmap.md — A6.P3 slice 3 marked SHIPPED;
  slice 4 (or A6.P4) scoped for #98 step-physics investigation
- CLAUDE.md — Currently-working-toward block updated

Test suite: 1148 pass + 8 pre-existing fail (baseline maintained).
