Migration: consolidate Echo6 docs to cortex with full infrastructure cleanup sync

- Documents recent infrastructure cleanup (8 CTs destroyed, 35 DNS records removed, Headscale cleanup)
- Adds 24 new runbooks covering Authentik, PeerTube, Meshtastic, RECON, Proxmox, Mailcow, Internet Archive, GPU routing
- Adds project documentation for headscale, vaultwarden, peertube, matrix, mmud, advbbs, arr stack
- Updates services.md, environment.md, caddy.md, authentik.md to match live infrastructure
- Removes 4 deprecated runbook duplicates (canonical versions live in projects/)
- Adds .gitignore for binary archives and editor temp files

+# MMUD — Mesh Multi-User Dungeon
+
+Text-based multiplayer dungeon crawler for Meshtastic LoRa mesh networks. BBS door games (LORD, TradeWars) adapted for 150-char mesh radio constraints, async play, 30-day wipe cycles.
+
+## Status
+
+**Phase:** Deployed and running — all 6 phases implemented, NPC conversation system live with Gemini 2.5 Flash.
+
+## Deployment
+
+- **Game Daemon:** CT 109 (192.168.1.109) on utility node, Docker container, Flask dashboard on port 5000
+- **Dashboard:** https://mmud.echo6.co (Last Ember — dark tavern aesthetic)
+- **SIM Nodes:** 6 meshtasticd LXC containers (CT 111-116) on utility
+  - EMBR (CT 111) — game server
+  - DCRG (CT 112) — broadcast
+  - GRST (CT 113) — Grist barkeep NPC
+  - MRN (CT 114) — Maren healer NPC
+  - TRVL (CT 115) — Torval merchant NPC
+  - WSPR (CT 116) — Whisper sage NPC
+- **LLM Backend:** Gemini 2.5 Flash via Google genai SDK (configured in DB `llm_config` table)
+- **Compose:** `/opt/mmud/docker-compose.yml` on CT 109
+- **Admin:** https://mmud.echo6.co/admin (session auth, password in docker env)
+
+## Repo
+
+`/home/zvx/projects/mmud` (GitHub: zvx-echo6/mmud)
+
+The repo contains a `CLAUDE.md` with full architecture, directory structure, and implementation guidance. **Read it first before any work.**
+
+## Key Files
+
+- `CLAUDE.md` — Architecture, patterns, gotchas
+- `docs/planned.md` — Complete game design document (~950 lines). Source of truth for all mechanics.
+- `docs/npc-lore.md` — NPC deep lore bible (5-layer Hearth-Sworn backstories, 514 lines)
+- `docs/worldbuilding.md` — Surface-level worldbuilding (Legend of Oryn, floor identities)
+- `config.py` — All game constants with rationale
+- `src/db/schema.sql` — Full database schema (migrations in `src/db/migrations/`)
+
+## Architecture
+
+- **Python 3.11+**, SQLite, Meshtastic Python API, Flask 3.x, Jinja2
+- **Docker:** python:3.11-slim, /data volume for SQLite DB
+- **6-node mesh topology:** EMBR (game), DCRG (broadcast), 4 NPC nodes
+- **150 characters per message** — hard ceiling from Meshtastic LoRa
+- **12 dungeon actions/day**, 30-day epochs, async-first
+- **828+ tests** — `python3 -m pytest tests/ -x -v`
+
+## NPC Conversation System
+
+NPCs use runtime LLM calls (the one exception to the "no runtime LLM" rule). Key features:
+
+- **TX Tag System:** LLM prefixes responses with `[TX:action:detail]` for game mechanics (heal, buy, sell, browse, gamble, hint, recap)
+- **Session Memory:** Per-player per-NPC conversation history with persistent memory summaries
+- **Deep Lore:** Five-layer backstory system (Surface → Observations → History → Truth → Unspeakable)
+  - Trigger word detection pushes toward deeper layers
+  - Interaction count tracks conversation depth per player per NPC
+  - "Soren" is a Layer 5 nuclear trigger for all 4 NPCs
+- **Easter Eggs:** Death memory (Maren), daily gamble (Torval), countdown (Whisper), late-epoch vulnerability (Maren), inter-NPC secret (Torval/Whisper)
+- **DummyBackend:** Keyword-based offline mode for testing without LLM
+
+## LLM Configuration
+
+- Model configured via `llm_config` table in SQLite DB (not env vars)
+- Currently: Gemini 2.5 Flash (`gemini-2.5-flash`)
+- API key stored in DB, manageable via admin panel at /admin/llm
+- **No `max_output_tokens` restrictions** — Gemini 2.5 Flash thinking tokens consume the budget, causing truncation. All backends have token limits removed.
+- Supports: Google (Gemini), Anthropic (Claude), OpenAI-compatible backends
+
+## Development Phases (All Complete)
+
+1. **Core Loop** — Message handling, parser, player creation, navigation, combat, death, action budget
+2. **Economy & Progression** — XP, leveling, gold, shops, gear, bank, healer
+3. **Social Systems** — Broadcasts, barkeep, bounty board, player messages, mail
+4. **Epoch Generation** — World gen, LLM narrative pipeline, secrets, bounty pools
+5. **Endgame Modes** — Hold the Line, Raid Boss, Retrieve & Escape, epoch vote
+6. **The Breach** — Breach zone gen, 4 mini-events (Heist, Emergence, Incursion, Resonance)
+
+## Gotchas
+
+- Gemini 2.5 Flash thinking tokens count against `max_output_tokens` — never set token limits
+- NPC greeting path uses `complete()`, conversation path uses `chat()` — different code paths
+- `npc_memory` table stores `turn_count` for interaction depth tracking
+- Death log table (`death_log`) tracks monster kills for Maren's memory feature
+- Town actions are always free — never charge dungeon actions in town
+- The design doc (`docs/planned.md`) is the source of truth — if code contradicts it, code is wrong
+
+## Notes
+
+- All regen/HP/damage numbers are targets — will need playtesting
+- SQLite single file DB, no ORM, raw parameterized SQL
+- Every outbound message must fit 150 chars — the formatter is the final gate
+- Container on CT 109 connects to 6 SIM nodes via TCP (ports 4403)
