Recent Changes & Evolution

The dLANDiscord project has evolved significantly since its inception in 2021. This document tracks the major shifts, including the 2026 architectural overhaul.

📅 May 18, 2026 - Model Migrations & Stability Fixes

Panic Recovery Overhaul

Root cause: Any unhandled panic permanently kills heartbeat/scheduler goroutines with zero logging and zero recovery — causing silent service degradation.

Changes applied:

• safeGo() helper wraps all 18 heartbeat goroutines with recover() + debug.Stack() logging
• Main scheduler goroutine (scheduler.go:665) and checkAndExecuteDueTasks() now have per-tick recover()
• SQLite WAL mode + busy_timeout=5000 on scheduler DB (matches observability pattern)

Affected loops: telemetry, resumption, subagent cleanup, project/company/team managers, memory cleanup, playbook discovery, Nikki/Liz work loops, architect audits, midnight snapshot, notes fix, self-evolution, async cleanup, CCTV polling/overnight, GitLab monitor, security audit, financial anomaly, WoW pulse, free games

Model Migrations (GLM-4.7 → GLM-5, Grok-4.3 for Nikki)

Nikki: openrouter/x-ai/grok-4.3 primary, fallback → glm-5 All other agents: glm-5 (Lenore, Nova, Oracle, Sasha, Sysadmin, Sysafe, + 10 others) Lia: glm-5-flash 7 playbooks: glm-4.7-flash → glm-4.5-air:free

Context Overflow Detection

Added ErrContextOverflow sentinel in llama_client.go. Triggered from both ReAct loop and Single-Shot paths. Falls back to gemini-2.5-flash-lite on context exhaustion.

Heartbeat Tweaks

Added isHostReachable() helper (1-ping, 3s timeout) for liveness checks.

WoW Health Check Playbook Fix

Failing daily on the 9am scheduler run for 7+ consecutive days.

🕰️ Historical Evolution

• 2021-2023: Initial development as a Discord bot with various integrated packages (WoW, crypto, etc.). AI integration began with basic Claude and OpenAI wrappers.
• 2024-2025: Modularization into specialized packages. The core assistant framework started to take shape with the introduction of planning and task decomposition.
• January 2026:
  • Claude Deprecation: The legacy claude package was retired. All AI interactions, including WhatsApp and image analysis, now route through the centralized assistant and localai packages.
  • Multimodal AI: WhatsApp image analysis migrated to use localai.QueryOllamaMultimodal (Ollama/Llama-server).
• March 2026:
  • Ollama to Llama Migration: A large-scale shift to use llama-server for local LLM inference, while retaining Ollama for multimodal tasks.
  • MrTool Implementation: Introduction of autonomous tool and skill creation for agents.

🚀 Major Updates (April 2026)

1. Robustness & Stability

• Deadlock Fixes: A critical deadlock in the session logging system was resolved by standardizing lock orders.
• Zombie Cleanup: The scheduler now features an automated cleanup for "zombie" tasks that were stuck in an 'executing' state due to system restarts.
• Nil Safety Audit: A comprehensive audit of all defer calls and pointer accesses in the assistant module was completed to prevent nil pointer panics.

2. Monitoring & Observability

• JSONL Session Logs: Every agent session now writes its events (thinking, tools, results) into a structured .jsonl file in real-time.
• Mission Control Fallback: Mission Control was updated to automatically read these JSONL files if the observability SQLite database becomes corrupted.
• Structured Audit Trails: All tool executions and agent decisions are logged with unique execution IDs to enable deep tracing and forensic analysis.

3. Intelligence Expansion & Agent Realignment

• New Specialized Agents:
  • Murloc (WoW Shaman): Dedicated AzerothCore analyst using a hybrid SQL/SOAP bridge for real-time player and server intelligence.
  • CommanderData (Ops Officer): Android disaster monitor tracking global telemetry (seismic, space weather, grid load, gov alerts).
• Security & Posture Shift: Responsibility for full perimeter security audits (LXC package/OS scanning) was moved to MrRobot to align with his paranoid guardian persona.
• Nightly Security Ritual: Coordinated audit where Gilfoyle (detecting pushes) summons SkriptKiddie (scanning CVEs) at 03:00 to analyze code changes.
• Adaptive Heartbeats: Expanded the heartbeat system to 18 concurrent loops, adding adaptive intervals (faster during day, slower at night) to optimize token usage.

4. Infrastructure & Tool Repairs

• CCTV Firmware Fix: Overhauled cctv_monitor.go with a raw HTTP polling implementation to bypass a Reolink firmware bug causing unmarshalling failures.
• Tactical Suite Upgrades:
• RoboCop: Added perimeter_event_summary and neighborhood_pulse (UK Police API).
• SkriptKiddie: Added leak_check (HIBP) and shodan_infra_lookup.
• Lenore: Fully transitioned to Executive Guardian for Liz, equipped with London-Hosting "Business Sorcery" tools (WHMCS/Jira).

🚀 Critical Fixes (April 2026, Continued)

1. WhatsApp LID→JID Resolution

• Issue: Async delegation notifications failed because WhatsApp LID format wasn't being resolved to JID format.
• Fix: Implemented 3-tier fallback in planner.go, scheduler.go, and wakeup.go:
  1. Direct ChatID use if already JID format
  2. Phone number extraction + @s.whatsapp.net suffix
  3. Fallback to stored ZombieParent ChatID
• Files: assistant/planner.go, assistant/scheduler.go, assistant/wakeup.go

2. Empty ChatID in ZombieParent Registration

• Issue: ZombieParent registration captured empty ChatID, breaking async notification delivery.
• Fix: Added fallback in AsyncCallAgent() to use stored parent ChatID when current is empty.
• File: assistant/planner.go

3. LLM Semaphore Timeout Handling

• Issue: Ollama requests cancelled while waiting for semaphore due to queue timeout overlap.
• Fix: Separate 30-minute queue timeout, reduced concurrent slots 5→3 to prevent saturation.
• File: assistant/ollama_client.go, assistant/llama_client.go

4. Reolink CCTV Search Parsing

• Issue: NVR returns object instead of array for certain queries, causing JSON unmarshal failures.
• Fix: Created searchRecordings() wrapper that handles both object and array responses.
• File: assistant/cctv_monitor.go

5. Playbook Placeholder Format

• Issue: Playbooks used [From Step X] format which isn't recognized by substitution engine.
• Fix: Corrected 7 playbooks to use {step_X_result} format.
• Files: assistant/playbooks/*.json

6. Planner Session Reliability

• Issue: WhatsApp-initiated planner sessions failed because LLM returned empty/text responses without calling get_capabilities.
• Fix: ProcessReActLoop now forces get_capabilities for ALL planner sessions regardless of source.
• File: assistant/planner.go

7. Shared Tools Full Definitions

• Issue: get_capabilities returned only tool names, not full definitions.
• Fix: GetSystemCapabilities now returns complete Tool structs.
• File: assistant/assistant.go

8. dMUD Stability & Concurrency Overhaul (Phases A-D)

• Issue: The dMUD engine suffered from 50+ identified concurrency issues, leading to deadlocks during reconnection and panics in mini-games.
• Fixes (20 Applied):
  • Phases A & B (Panic Prevention): Added nil guards to Send() and CurrentRoom, fixed Blackjack empty deck panic, and implemented sync.Once for config watchers.
  • Phase C (UsersMu - High Impact): Introduced UsersMu RWMutex to the Room struct. This resolved data races in chat broadcasting, ambient rendering, and NPC script interactions by protecting the Users map.
  • Phase D (Blocking & Deadlock Mitigation): Optimized the Register() flow by moving bcrypt hashing outside of mutex locks, reducing global lock contention. Added non-blocking selects for internal save channels.
• Files: dmud/room.go, dmud/user.go, dmud/server.go, dmud/config.go, dmud/games.go
• Result: Server-side panics and "session hangs" during multi-user interactions have been eliminated.

🎙️ Voice Pipeline & UI Overhaul (April 2026)

1. WhatsApp Voice Note Dual Output

• Issue: Voice note responses couldn't include image generation results; agent routing defaulted to "sysafe" instead of last-used agent.
• Fix:
  • Added Callback to voice QueryOptions so image generation results are delivered
  • Added GetLastUsedAgent() check before defaulting agent selection
  • Added SaveLastUsedAgent() call after voice responses for sticky agent persistence
• Files: dwhatsapp/dwhatsapp.go

2. Lenore TTS Configuration

• Issue: Lenore agent had no TTS voice configuration, causing fallback to default voice.
• Fix: Added Lenore's Inworld voiceID (Selene) to TTS config map and assutils.go voiceID registry.
• Files: assistant/tts.go, assistant/assutils.go

3. TTS Sanitization

• Issue: Voice notes included raw emojis and markdown formatting, causing unnatural TTS output.
• Fix: Added SanitizeForTTS() function that strips emojis, markdown, and code blocks before TTS synthesis.
• Files: assistant/tts.go

4. Voice UI Kiosk Mode & Accessibility

• Issue: Voice UI (voice.html, wake.html) wasn't optimized for tablet/kiosk use and lacked accessibility features.
• Fix:
  • Added kiosk mode detection (?kiosk=true&agent=xxx) with hidden controls and larger touch targets
  • Added aria-live regions for screen reader announcements
  • Added responsive CSS for tablet/mobile layouts
  • Changed hardcoded "Dan:" to "User:" in history display
• Files: assistant/static/voice.html, assistant/static/voice.js, assistant/static/wake.html, assistant/static/wake.js

5. Lenore Theme & TTS Default Selector

• Issue: Lenore agent had no visual theme; TTS selector lacked "Agent Default" option.
• Fix:
  • Added Lenore theme (Indigo/MediumPurple) to AgentThemes map
  • Added "Agent Default" TTS option that respects per-agent voice configuration
  • Updated backend nikki_voice.go to handle "default" TTS fallback
• Files: assistant/nikki_voice.go, assistant/static/voice.js, assistant/static/wake.js

6. Canvas Blur Performance

• Issue: CSS filter: blur() on canvas was GPU-intensive, causing performance issues on tablets.
• Fix: Moved blur effect from CSS filter to JavaScript rendering in aura.js for better performance control.
• Files: assistant/static/aura.js

🚀 Major Updates (April 2026 - Continued)

5. IRC Platform Enhancements

• Automatic Channel Registration: Implemented ChanServ integration for automatic channel registration on join
• Personal Agent Channels: Each agent bot now has a personal channel for private communications
• Specialized Channels: Added #NOC (infrastructure metrics), #dBot (bot operations), and #Solana (blockchain monitoring)
• Intelligent Dynamic Topics: Channel topics now update automatically based on system state and agent activity
• Identity-Aware Message Processing: Fixed multiple reply issue by making message processing identity-aware
• ErgoIRCd Integration: Enhanced SASL/nickname handling and improved connection stability
• Log Throttling: Implemented log throttling to prevent message delivery hangs
• Operator Status: Master Dan automatically granted operator status on join

6. Context Optimization & Token Efficiency

• Active LLM Summarization: Implemented middle-out context compaction using active summarization for long sessions
• Tool Result Hashing: Added hashing to prevent redundant context bloat from repeated tool calls
• Prompt Reordering: Reordered prompts to maximize LLM prefix caching efficiency
• Conversation Summary Limits: Optimized truncation limits (3000 characters) for better context management
• Intelligent Task List Pruning: Implemented smart pruning for task list tool to reduce token usage
• Circuit Breaker: Extended circuit breaker to all adaptive planner LLM call sites with fallback loops
• Session Counter Reset: Reset session counters on new user message with 2s delay before LLM retries

7. Dual-Platform Notification System
