refactor(runtime): own local movement and outbound cadence
Move the canonical local movement controller, body/motion managers, object clock, movement wire data, and MTS/jump/AP sender into AcDream.Runtime. Replace process skill defaults with typed Runtime character options, make graphical and direct commands borrow one autorun owner, retain the construction-time PartArray seam, and include movement in terminal ownership convergence. Preserve the accepted pre-inbound movement/jump and post-inbound autonomous-position order while moving the exact packet/cadence fixtures into Runtime tests. Add graphical/direct parity, two-instance isolation, teardown, allocation, architecture, and divergence-path coverage. Co-authored-by: Codex <noreply@openai.com>

// ── Indoor-flap root cause: resting-body bit-stability ────────────────────
|
||||
//
|
||||
// The indoor render "flap" (textures battling at the cottage doorway) is
|
||||
// portal-flood membership instability. PortalVisibilityBuilder.Build is a
|
||||
// proven-deterministic pure function, so the membership can only flip if its
|
||||
// INPUT (the camera eye, derived from the player RenderPosition) varies.
|
||||
// Live 6-dp capture (pvinput.log:54) shows the player RenderPosition carries
|
||||
// a perpetual ~1-ULP flicker at rest (Z 94.000000 <-> 93.999992 — exactly one
|
||||
// float mantissa step). ComputeRenderPosition is Vector3.Lerp(_prevPhysicsPos,
|
||||
// _currPhysicsPos, alpha), and Lerp(a, a, t) == a exactly, so a jittering
|
||||
// RenderPosition at rest means the physics body's resting Position is NOT
|
||||
// bit-stable between ticks. Retail's authoritative local position is bit-stable
|
||||
// at rest (validate_transition -> kill_velocity on every grounded contact), so
|
||||
// retail never flaps.
|
||||
//
|
||||
// This test pins the physics-side invariant: a grounded body with no input
|
||||
// must hold a byte-identical position across many frames. It PASSES — which
|
||||
// is itself the evidence: the physics resting position is bit-stable, so the
|
||||
// doorway flap is NOT a physics-rest jitter. See
|
||||
// docs/research/2026-06-08-flap-physics-diagnosis-REFUTED-its-render-membership.md

|
||||
// doorway portal under a sweeping camera eye). Kept as a regression guard.
