docs(issues): #464 owner-confirmed artifact pose pinned with probes — ordinary camera state, hall interior drawn through the stairwell's open far face (S4)

Owner client with both probes: root 0xF4180114, eye (39.89,17.25,182.36),
sweep uncontacted; the hall's interior shows above the bottom arch where
retail shows the solid far face, which the DAT gives as five exit portals.
The retail capture cathedral-stair-arch is requested as the fix oracle.

 **OWNER 2026-09-03 21:55 — RETAIL AXIOM:** the front-view frame above (`464-arch-05-yawright500-out.png`: the eye in the hall beyond the open face, the stairs as floating slabs without side walls) EXISTS IN RETAIL AS WELL. It is therefore not a defect (it joins the cathedral exterior-slab leak as a retail axiom; do not fix, reproduce). The owner's actual artifact is seen "when looking towards the arcs on the other side" — pose and camera direction still to be pinned (the owner is asked for a `/loc` line and the direction, ideally the probe-on launch above with a screenshot). The walk-transcript run at the front-view eye (`logs/selfgate-20260903-215332-464-walk`, route `route-464-walk.txt`) is kept as the record of that retail-legitimate frame: root `0xF4180109`, 10 `DC` cells, 18 `EC`/`OC` views, 16 `BLD` turns.
 
+**OWNER-CONFIRMED ARTIFACT POSE (2026-09-03 22:04, owner client launched by the lead with both probes on, log `logs/launch-464-20260903-220134.log`, frame snapshot `logs/launch-464-snapshot-220426.log`):** `/loc` = `0xF4180113 [39.502899 19.832422 180.976700] 1 0 0 0` (facing +y, down the stairs toward the arches at the bottom), camera at the default distance tilted slightly up. Probe frame, stable for 400+ frames: `[flap-cam] root=0xF4180114 viewerCell=0xF4180114 playerCell=0xF4180113 res=None eyeInRoot=Y eye=(39.89,17.25,182.36) player=(39.50,19.83,180.98)`, `[flap-sweep] ok=True desiredBack=2.61 eyeBack=2.61 pulledIn=0.00 collNormValid=False`, `[cathedral-stair] rootFlood=[107=0,112=1] visited=[107=1,112=1]`. The camera is in an ordinary state; the render root is the upper stairwell cell. **Owner screenshot at that frame:** looking down the stairs at the gothic arch; above and around the arch, where retail shows the stairwell's solid far face, acdream draws the neighbouring hall's INTERIOR: hanging column pieces cut off in mid-air, the vault, hall walls above the stairwell's own walls, and an unsealed pale-pink quad beside the character's head. In the DAT that far face of `0x114` is not a wall: it is three EXIT portals (polys 30/31/32, plane y=24) plus `0x113`'s two exit triangles, so the region is the stairwell's open face rendered by the outside-view block (exit views, punches, seals, the gated Z clear) — retail resolves it to something solid, acdream lets the hall's cells show through. **Classification final: S4 depth/alpha, the exit-view punch/seal order at the stairwell's open face, seven exit views from root `0x114`.** The owner is asked for ONE retail capture at exactly this pose (`cathedral-stair-arch`: the oh-capture walk + alphadepth templates) as the oracle for the fix contract; the lead's transcript reproduction at this pose follows (`route-464-owner.txt`).
