Erik 67005e21f1 docs(handoff): A6.P3 #98 Step 6 — issue + claude.md handoff
Final step of the apparatus plan. Updates ISSUES.md issue #98 and
CLAUDE.md's M1.5 status to reflect:

- The apparatus completed (Steps 1-5 land in commits 35b37df28c282a).
- The real divergence: retail's sphere is at world Z ≈ 94.48 (resting
  on cottage floor) when find_walkable accepts; acdream's failing-
  frame sphere is 2.47m lower at world Z ≈ 92.01.
- The four fix targets, in priority order. Fix plan is the NEXT plan,
  scoped to Target 1 (step-up + ramp climb Z gain) or Target 2
  (cottage-cell sphere reference).
- The replay harness (Issue98CellarUpReplayTests) is the test loop —
  any fix that doesn't change the failing assertions is not the fix.

Today's commit graph on top of slice 5 (cf3deff):
  35b37df  triage — revert neg-poly + bldg-check experiments
  f62a873  Step 2 — cell-dump probe + roundtrip test
  3f56915  Step 2 capture — 3 real-geometry cell fixtures
  856aa78  Step 3 — deterministic replay harness (7 tests)
  6f666c1  Step 4 — retail cdb find_walkable capture script
  28c282a  Step 5 — replay vs retail divergence comparison
  (this)   Step 6 — ISSUES.md + CLAUDE.md handoff

Test baseline: 1167 + 8 (8 pre-existing failures, +19 new passing
tests across the apparatus). Build green throughout.

A6.P3 #98 is now in evidence-driven mode. Fix plan starts from the
divergence doc at
docs/research/2026-05-23-a6-p3-issue98-replay-comparison.md.

Pickup prompt for the fix-plan session is in §"Pickup prompt for the
fix plan" of that doc.
