@@ -508,8 +508,31 @@ morning was a Git Bash path-rewriting bug in the walk's own helper, not the rigs
   installed beside the bridge…". Hello said `missing`, then `patched`/`ready` once the helper was loaded
   again.
 
+**The site half, walked 2026-09-29** on a local core (website `main` `f0e7d2a`) with this branch's module,
+against `rust-carbon`. `rust-oxide`'s fresh egg installed the last released sidecar, which speaks protocol 12,
+so the site refuses it until protocol 13 ships:
+
+- **The page, in the browser as an admin:**
+  - Each server's line: Carbon's ZoneManager 3.1.14 with 69 flags, and "domes available".
+  - The edit form: the flags in their groups with the preset's ticked, the servers, and the settings with
+    their bounds.
+  - A save with comfort 3 was refused under the form ("comfort is 0 to 1, not "3""). Corrected, it saved,
+    and the preset's line updated.
+  - The sidebar row. No console errors.
+- **The API:** a flag Carbon does not have was refused, naming the server. So were an out-of-range setting,
+  a preset for no server, and a second "arena" on the same server (409).
+- **The step:**
+  - The Options dropdown's row value is the preset's line (D210).
+  - After the preset was edited, the published step still held its own old line. Picking the preset in the
+    editor wrote the new one.
+  - The dome dropdown carries D212's labels.
+  - A draft with `NoFlying` failed its dry run with that reason.
+- **A run through the whole path:**
+  - The site opened the zone on Carbon: the preset's flags and settings, the popup messages, and ZoneDomes'
+    Standard dome at stack 2.
+  - The run's cleanup removed it, leaving ZoneDomes' data empty.
+
 **Still to walk:**
-- **The site half:** the presets page, and a step made from a preset.
 - **The in-game rows, deferred by the org lead (2026-09-29) to the later in-game walk, with §5.7's:**
   - The flags hold for a player without the exemption and not for one with it.
   - The enter and leave messages arrive as chat and as a popup.
