+# Nanobot
+
+## Purpose
+
+Scout agent for Anthony's estate. Handles quota notifications and daily agent briefings. Runs on CT333 alongside ZeroClaw (different software, same container).
+
+## Location
+
+- **Container:** LXC CT333 (`clawtest`)
+- **Tailscale IP:** `100.122.189.81`
+- **Port:** 8766 (Nanobot), 8900 (previously, now DOWN)
+- **Shares container with:** [[agents/zeroclaw]]
+
+## Current State
+
+- **Status:** Active (scout role)
+- **Cron schedules:** Enabled with recent ok status
+- **Quota notifications:** Enabled — kept active per Anthony's direction
+- **Daily briefing:** Enabled
+
+## Phase One Review (2026-08-08)
+
+CT333 schedules remained enabled and healthy during the seven-day review.
+
+## Key Rules
+
+- **Nanobot schedules remain enabled unless Anthony explicitly approves changes.**
+- **Do not conflate with ZeroClaw.** They share CT333 but are different software.
+- **Do not conflate with Open-Claw.** Open-Claw is VM 403, not CT333.
+
+## Relationship to ZeroClaw
+
+Nanobot and ZeroClaw share LXC CT333 (`clawtest`):
+- **Nanobot:** JSON config, Telegram gateway bot
+- **ZeroClaw:** TOML config, autonomous daemon (root)
+
+They are different software with different configs, different users, and different purposes. Restarting one does not affect the other.
