The user is wedged at the top of Neftet rock plateaus, jumps sink into the mesh, and a corpse falls straight through. ACDREAM_PROBE_REACH already ruled out its own domain: blocked=0, every candidate tested-ok. Three candidates remain — terrain support, a collision mesh not where its visual is, or the transition wedging on an unobstructed path. ACDREAM_PROBE_RESOLVE alone cannot separate them. It prints a three-value contact-plane token, no plane normal, no plane height, no terrain sample and no plane provenance, so all three produce the same line. Two additions: [support] — one line per resolve for EVERY body, not just the player. A corpse is a plain physics body with no player-specific logic, so its fall-through is the cheapest available control on "movement code vs geometry data", and it is invisible to any player-filtered probe. The line samples the outdoor terrain INDEPENDENTLY at the body's own out-XY and prints the contact plane's own height at that same XY. Two heights at one point make support=terrain / object / none a measurement rather than an inference, and cpSrc= names the site that asserted the plane so provenance and classification cross-check. [geom] — once per GfxObj that comes near a mover: the object's physics-BSP vertex cloud against its visual mesh AABB in the same local frame, through the same prepared accessors the resolver queries. verdict=coincident REFUTES the working hypothesis for that object outright; no-physics-bsp / empty-physics-bsp / displaced / extent-mismatch each name a specific data defect. Built to refute, not to confirm — two diagnoses on this defect's lineage have already been refuted by measurement. ACDREAM_WIRE_MESH upgrades the existing F2 overlay, which drew a broadphase proxy cylinder for BSP objects and so could not answer the question at all, to the real physics-BSP polygon edges (cyan) beside the visual mesh box (magenta) and the terrain surface (yellow). Own class per code-structure rule 1. The provenance latch lives on PhysicsDiagnostics, not on CollisionInfo. Two fields there first — the obvious home — broke the flat/graph differential referee and the scratch-reset poison test, both of which compare CollisionInfo member-for-member. Teaching either to skip a member is a one-line green fix that puts a permanent hole in a referee whose whole job is comparing everything. Captured as feedback_probe_state_off_compared_types. Seven tests cover the support classifier's boundaries: a wrong classifier does not fail to answer, it answers confidently wrong. Gates: Release build 0 errors; complete suite 11,225 passed / 4 skipped / 0 failed from a cleaned tree — baseline 11,218/4/0 plus exactly the seven new tests, skips unchanged. Issue #337 filed with the symptom set, what is ruled out, and a table of what each possible output means. All of this is TEMPORARY and recorded for stripping with the physics-probe family.

|
||
// • Candidate 1 — AP-87's `bodyToTarget > 4 m` body snap in
|
||
// RuntimeRemoteSteadyStatePosition.ApplyInterpolate (:129-137).
|
||
// • Candidate 2 — InterpolationManager's own retail-faithful
|
||
// `node_fail_counter > 3` snap-to-tail (:458-467; retail
|
||
// InterpolationManager::UseTime @0x00555f20). That code is CORRECT
|
||
// and is only reachable because §1 froze the body; this probe
|
||
// OBSERVES it and must never be read as a reason to change it.
|
||
// Both emit `[remote-slide-snap]` with a distinct `producer=` tag, so
|
||
// one grep finds every blip and the tag alone answers "which one".
|
||
//
|
||
// The same family also settles the diagnosis's two load-bearing NOT
|
||
// ESTABLISHED items:
|
||
// • #1 (Shape A vs Shape B) — `[remote-slide-up] wireGrounded=` is the
|
||
// raw ACE PositionFlags.IsGrounded bit for the accepted packet,
|
||
// emitted at the ONE routing point both remote arms pass through,
|
||
// AHEAD of the NoPositionOperation early returns, so a Shape-A slide
|
||
// (every packet `wireGrounded=false disp=NoPositionOperation`) is
|
||
// visible even though acdream writes nothing for it.
|
||
// • #2 (is the roof steep in OUR collision data) —
|
||
// `[remote-slide-tick] bodyCpNz=/rsCpNz=` against `floorZ=`.
|
||
// `[remote-slide-vec]` covers the 0xF74E half of NOT ESTABLISHED #4: an
|
||
// absence of lines during a slide is itself the answer.
|

//
|

// Pure reads only. Nothing here gates, orders, or mutates production
