docs(runicnpc): 9d player session, all fifteen rows pass

The org lead played every client-only row on both rigs on 2026-10-09 (Rust 25797215,
Oxide 2.0.7815, Carbon 2.0.262). Records the results, the decisions the session made
(D323-D325), what was asked for next (dome stack 3, the PopupNotifications banner),
the Carbon Kits-reload finding, and two walk artifacts.

+**9d, the player session (2026-10-09).** The org lead played every row, on Rust 25797215 with Oxide 2.0.7815 and
+Carbon 2.0.262. **All fifteen pass** (seven on Oxide, eight on Carbon):
+
+- **Death screen:** "Road Bandit" with a revolver at 2.8 m (Oxide), and the Juggernaut on Carbon. The portrait slot
+  shows Rust's own logo, as for any killer without a Steam account, so the profile's name costs nothing.
+- **`/rnpc` in chat:** the verb list, "Placed …" with the cost warning, `remove`, all readable. **Boss bar:** steady,
+  with the help line and its two adds, the enraged line, and the death line. **Press E:** the window opens and
+  closes cleanly (Oxide). **Locked crate:** dropped showing 17 minutes. **Rockets and grenades:** each hook fired
+  and counted; a lobbed grenade raises `OnExplosiveDropped`, which counts too. **Zone:** enter and leave messages
+  in chat and as a popup, and the dome. **Chat title (Carbon):** "[Player] Exterminator whitlocktech".
+
+What the session changed or asked for:
+
+- **D323 and D324** (each example its own outfit; every item at full durability) and **D325** (`/rnpc here` stands
+  the NPC a metre in front, facing you). The four kits were rewritten on both rigs by resetting `examplesWritten`.
+- **Asked for, to build next:** the default dome stacks **3** spheres, not 1 (chosen by eye at noon), and a
+  recommended PopupNotifications look: a banner across the top (left 0.15, bottom 0.87, width 0.7, height 0.07),
+  no close button, Roboto Condensed Bold at 18. The docs show it, and the installer and the Pterodactyl egg write
+  it where PopupNotifications' config is missing or still at the plugin's defaults.
+- **Found, not fixed:** on Carbon, the automatic Kits reload after the first load wrote the example kits did not
+  take: `s6bossc` stayed refused ("no kit 'rnpc_juggernaut'") until Kits was reloaded by hand. It was a hot load,
+  not a boot, so a fresh server may not see it. Oxide was fine.
+- **Walk artifacts, not faults:** the harness's own players (`11400000001` and up) hold NPC kills on the rigs'
+  leaderboards, which pushed the org lead out of a top-3 title rule until it was widened for the session.
+  `/rnpc here` makes a placement that respawns, so a boss placed that way comes back until it is removed.
+
 **9e. The cutover and release (D311, D313).** Only after the walk passes. In order: `runicnpc-rust` `edge` → `main`
 as v1.0.0 (its Gitea release is the only download); `rust-plugins`, `rust-link` and `installer` `edge` → `main`,
 and the bundle that pins all four; `module-rust` `edge` → `main` with RunicNPC required. Each release is checked
