Erik f04ea90050 ship(phys): A6.P3 slice 1 — Indoor ContactPlane retention COMPLETE 
Slice 1 ships the strip-synthesis + Mechanism B (LKCP restore) fix
addressing A6.P2 Finding 2. Includes:

  - scen3_inn_2nd_floor_postfix paired capture (retail.log + decoded
    + acdream.log) as verification artifact. acdream cp-write count
    dropped from 86,748 to 25,082; per-unit-of-activity rate dropped
    63x (164.61 -> 2.60 cp-writes per cell-cache event).

  - Findings doc (docs/research/2026-05-21-a6-cdb-capture-findings.md)
    appended with slice 1 SHIPPED section: commit map, scen2/scen3
    pre/post comparison tables, user happy-test results, status of
    each A6.P2 finding (Finding 1 CLOSED as side-effect, Finding 2
    PARTIALLY CLOSED with remaining 99.3% from L622 seed flagged
    as #96, Finding 3 + #95 still open), slice 2 recommendation.

  - Issue #96 filed: "Per-tick PhysicsEngine.ResolveWithTransition CP
    seed contributes 99.3% of post-slice-1 CP writes." Slice 2 target.
    Sketch options: remove entirely / gate by change-detection / no-op
    guard inside SetContactPlane.

  - Issue #97 filed: "Phantom collisions + occasional fall-through on
    indoor 2nd floor." User-reported during happy-testing. HYPOTHESIS:
    side-effect of #96; falsifiable by re-testing post-slice-2.

  - CLAUDE.md updated: Currently-working-toward block now points at
    A6.P3 slice 2 (#96) as the active phase. M1.5 building/cellar
    demo half is ACHIEVABLE NOW (slice 1 unblocked the physics).

  - Roadmap updated: A6.P3 broken into 3 slices, slice 1 marked
    SHIPPED with commit history.

KEY USER-VISIBLE OUTCOME: stairs + cellar descent now WORK in acdream
(user happy-test confirmed walking up/down inn stairs multiple times,
walking down to cellar). A6.P2 Finding 1 (dispatcher entry frequency
mismatch) confirmed as secondary effect of Finding 2 — closed without
explicit Finding 1 work, as A6.P2 hypothesized.

REMAINING CONCERNS for slice 2 + future:
  - L622 per-tick seed (#96) still firing 24,906 times in scen3 postfix
  - Phantom collisions + fall-through on 2nd floor (#97)
  - See-through-walls indoors (#95, separate scope)
  - Indoor lighting broken (A7 scope)

Test suite: 1148 pass + 8 pre-existing fail (baseline maintained;
T3 IndoorContactPlaneRetentionTests adds the +1).
