+## Addendum — owner check of 2026-09-03 morning and the fixes
+
+Owner verdicts on `4b0b29e4`: Facility Hub PASS, Holtburg house PASS, cathedral
+leak unchanged and not worse (S3/S4). Two new findings:
+
+1. **Building parts through terrain (Holtburg).** Doorway-sized fragments of
+   the houses on the terrace below show through the hill. Mechanism: the
+   building exit-portal depth punch (`PortalDepthMaskRenderer`) is drawn with
+   depth compare `Always` + write for every visited cell's exit portal, so a
+   doorway behind terrain punches far depth through it. Pre-existing; owned
+   by S4 (punch/seal work). Not touched in S2.
+2. **Portal-exit haze missing.** FIXED at `f6b4584b` (S2 chunk 6). Root
+   cause: the server keeps the player Hidden until LoginComplete at reveal
+   completion (retail-correct); the Hidden-state cloud's emitters spawn in the
+   arrival cell but were drawn only through the owner's registry rows, and a
+   hidden owner's shadow is suspended. Retail gives every emitter its own cell
+   membership (`add_particle_shadow_to_cell` 0x00514a70); chunk 6 ports that.
+   Evidence: `logs/selfgate-20260903-062522-haze-chunk6/artifacts/screenshots/h02-arrive-400ms.png`.
+
+**Owner re-check:** portal anywhere; the purple cloud should surround the
+character for the moment between the world appearing and the character
+materializing. Then G2 closes on your word.
