+
+Built in Rust-Plugins and Module-Rust as §14.3.6 planned it (D374), specified in
+[PROTOCOL.md](../../rust-link/PROTOCOL.md) §20.10. **No Rust-Link change**: the sidecar forwards hello whole.
+`PROTOCOL_VERSION` stays 14. Builds: Rust 25902425, Oxide 2.0.7830, Carbon 2.0.262, ZLevels Remastered 3.3.1 on
+both rigs, each the newest.
+
+**What was built:** hello's `integrations.zLevels` (`{ loaded, version }`, found by the plugin name
+`ZLevelsRemastered`); hello sent again when ZLevels loads or unloads; `rg.world` prints `zLevels=`; and Server
+settings' plugin line: *"ZLevels 3.3.1 is loaded — an event may lend its XP boosts (zlevelsremastered.vip1 to
+vip3) as permissions."* No level is read and nothing is stored.
+
+**Settled in the code, and overrulable:**
+
+1. **The plugin line names the three VIP permissions as ZLevels ships them.** An operator who renamed them in
+   ZLevels' config sees the shipped names on that line; the lend step's picker lists whatever ZLevels really
+   registered (§12.2), so nothing is lent wrong.
+2. **The ZLevels group names** (`zlevelsvip1`–`3`, ×5–×7) are not mentioned. They are groups, and a run lends
+   permissions, not groups.
+
+**Tests.** No new automated test: the servers page's lines are in a `.jsx` file the client's runner cannot
+import, as §14.3.16–§14.3.19's were, so the line is checked at the walk. Full suites: Module-Rust server 643/643
+and every check (imports, bundle, swagger, engagement), client 95/95, the build and externals; Rust-Plugins'
+`checkPlugin.js` (84 hooks) and its 18 tests. On both rigs the bridge compiled and loaded, and `rg.world` read
+`zLevels=absent`, then `zLevels=3.3.1` once ZLevels loaded, then `zLevels=absent` once it was removed. Both rigs
+were then cleaned of ZLevels and its files, and put back on the protocol-13 bridge.
+
+**Walk rows** are §14.3.6's, with one more: Server settings' line for a server with and without ZLevels.
