docs(issues): #464 — the front-view frame is a retail axiom (owner); the real artifact is toward the arches on the other side

Also commits the walk-transcript route used at that eye.

 **REPRODUCED from the script (lead, 2026-09-03 21:51, `logs/selfgate-20260903-215041-464-arch/artifacts/screenshots/464-arch-05-yawright500-out.png`, route `route-464-arch.txt`, code `c3b989305`, both probes on):** at the top pose, CameraRotateRight held 500 ms swings the chase camera to the FRONT of the player (the orbit covers about 180 degrees in that time); zooming out from there drives the boom 11.03 m forward with `pulledIn=0.00` and `collNormValid=False`: the eye passes through the stairwell's open y=24 face and comes to rest at `(36.07, 29.58, 185.79)` in cell `0xF4180109`, the hall (`[flap-sweep] ok=True viewerCell=0xF4180109`, `[flap-cam] root=0xF4180109 eyeInRoot=Y res=None`, `[cathedral-stair] rootFlood=[107=1,112=0] visited=[107=1,112=1]`). The frame is the owner's picture: the player on stair slabs that float with no side walls, the hall's arches, green terrain and sky through the arch, one pier. The eye is legitimate (the investigation's difference 7: retail's viewer sphere passes that open face too, the tower shell collides only from its origin land cell), so the defect is the DRAW of the stairwell cells from an outside root: `0x112` is visited but not root-flooded (reached through the building's exterior portals), and its walls, `0x113`'s and `0x114`'s are not on screen. This is the S3/S4 building-seen-from-outside path (the outside-view block, exit views, building portal stab lists), not the camera. A walk-transcript run at this exact eye follows; the retail walk/alphadepth capture at this eye does not exist in the oh-capture kit and is the ONE capture to ask the owner for (retail: `/teleloc F4180113 39.502899 19.589222 181.119247 1 0 0 0`, swing the camera to the front of the character, zoom fully out, run the `oh-capture` walk + alphadepth templates).
 
+**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.
