Task: Add Darkcragg Depths broadcast node to planned.md

Edit /home/zvx/projects/mmud/docs/planned.md in place.

---

Edit 1: Update NPC Sim Nodes section

Find the **Network Architecture — NPCs as Mesh Nodes:** block inside ## The Last Ember — Town Hub. Replace the node list (the 5-item bullet list starting with - **EMBR** through - **WSPR**) with:

- **EMBR** — The Last Ember. The game server. All game commands go here. Responds with direct action results only.
- **DCRG** — The Darkcragg Depths. One-way broadcast node. All dungeon events come from here — deaths, bounty progress, Breach opening, regen ticks, boss phase transitions, discoveries, level-ups. Does not accept commands. The dungeon is alive on the network.
- **GRST** — Grist. DM this node to talk to the barkeep.
- **MRN** — Maren. DM this node to talk to the healer.
- **TRVL** — Torval. DM this node to talk to the merchant.
- **WSPR** — Whisper. DM this node to talk to the sage.

This splits two distinct streams: EMBR only sends direct responses to your actions. DCRG is the ambient feed of what's happening in the world. The NPCs are people you talk to. Six nodes total, one game DB backing all of them.

Edit 2: Add DCRG rules to the rule layers

Find **Three rule layers (checked in order):**. Insert a new section BEFORE Rule 1:

**DCRG rules (broadcast node):**
- DCRG never accepts inbound messages. If a player or unknown node DMs DCRG, it responds with a static message: `"The Darkcragg does not answer. It only speaks. DM EMBR to play."`
- All tier 1 and tier 2 broadcasts are sent FROM the DCRG node, not EMBR.
- Targeted broadcasts (multi-room puzzle feedback) are also sent from DCRG as DMs to qualifying players.
- DCRG is the voice of the dungeon. When someone dies, when the Breach opens, when a bounty falls — it comes from the Darkcragg.

Edit 3: Update Broadcast System section

Find ## Broadcast System. Find the first paragraph or description of how broadcasts work. Add this line at the end of the introductory text, before any subsections:

All broadcasts are sent from the DCRG (Darkcragg Depths) sim node, not the main EMBR game node. This separates the ambient world feed from direct command responses. EMBR talks to you. The Darkcragg talks about everyone.

Edit 4: Update Resolved Decisions

Find the resolved decision about NPC live conversations that starts with - NPC live conversations: NPCs are sim nodes. Replace it with:

- Mesh node architecture: 6 sim nodes — EMBR (game commands + responses), DCRG (one-way dungeon broadcasts), GRST/MRN/TRVL/WSPR (NPC conversations). One game DB backs all of them.
- NPC conversations: Players DM NPC nodes directly. Three rule layers: unknown node gets static onboarding, known player not in bar gets static rejection, known player in bar gets full LLM conversation. Session-only memory, 5/day rate limit per NPC, falls back to pre-generated dialogue on failure.
- DCRG is broadcast-only — does not accept commands. All tier 1/2 and targeted broadcasts route through DCRG.

---

Edit 5: Update Open Questions

Find the open question - NPC sim node deployment. Replace it with:

- Sim node deployment — which host runs meshtasticd with 6 identities (EMBR, DCRG, GRST, MRN, TRVL, WSPR), TCP routing to game LXC
