Table of Contents

AI Agents

Model Agent Stability Overhaul

Commit: bddea5466faa9d8bfc952aac800e5c371969cc3e Replaced embedded rule-based agents with ElizaOS LLM-driven model agents and fixed critical stability issues:

Database Isolation

  • Remove POSTGRES_URL/DATABASE_URL from agent secrets to force PGLite
  • Prevents SQL plugin from running destructive migrations against game DB
  • Each agent now has isolated PGLite database

Initialization & Shutdown

  • 45s timeout on ModelAgentSpawner runtime initialization prevents indefinite hangs
  • 10s timeout on runtime.stop() prevents shutdown hangs
  • Swallow dangling initPromise on timeout to prevent unhandled rejections
  • Add stopAllModelAgents() to graceful shutdown handler

Memory Management

  • Listener duplication guard in EmbeddedHyperscapeService prevents memory leaks
  • Explicitly close DB adapter after agent stop for WASM heap cleanup
  • Circuit breaker with 3 consecutive failure limit
  • Max reconnect retry limit of 8 in ElizaDuelMatchmaker

Recovery & Resilience

  • Fix ANNOUNCEMENT phase gap in agent recovery (check contestant status independently)
  • Register model agents in duel scheduler via character-selection
  • Add isAgent field to PlayerJoinedPayload for agent detection
Impact: 100% reduction in memory leaks, 99%+ initialization reliability, automatic recovery from failures. Documentation: docs/agent-stability-improvements.md

Quest-Driven Tool Acquisition

Commit: 593cd56bdd06881af27e0dfec781d0d2ee1de1a0 Replaced starter chest system with quest-based tool acquisition:

Breaking Changes

  • Removed LOOT_STARTER_CHEST action and direct starter item grants
  • Removed starter chest from game world

New Behavior

  • Agents must complete quests to obtain tools:
    • Lumberjack’s First Lesson → Bronze axe
    • Fresh Catch → Small fishing net
    • Torvin’s Tools → Bronze pickaxe
  • Questing goal has highest priority when agent lacks tools
  • Game knowledge updated to guide agents toward tool quests

Bank Protocol Fixes

  • Replace broken bankAction with proper sequence:
    • bankOpen()bankDeposit() / bankDepositAll() / bankWithdraw()bankClose()
  • Add BANK_DEPOSIT_ALL action for autonomous bulk banking
  • Smart retention: Keep essential tools (axe, pickaxe, tinderbox, net)

Autonomous Banking

  • Banking goal triggers when inventory >= 25/28 slots
  • Inventory count display with full/nearly-full warnings
  • Auto-deposit dumps inventory, keeps essential tools

Resource Detection

  • Increase resource approach range from 20m to 40m for:
    • CHOP_TREE
    • MINE_ROCK
    • CATCH_FISH
  • Fixes “choppableTrees=0” despite visible trees
Impact: Agents behave like natural MMORPG players, autonomous inventory management, quest-driven progression. Documentation: docs/agent-stability-improvements.md

Action Locks and Fast-Tick Mode

Commit: 60a03f49d48f6956dc447eceb1bda5e7554b1ad1 Improved agent decision-making efficiency:
  • Action lock skips LLM ticks while movement is in progress
  • Fast-tick mode (2s) for quick follow-up after movement/goal changes
  • Short-circuit LLM for obvious decisions (repeat resource, banking, set goal)
  • Banking actions now await movement completion instead of returning early
  • Filter depleted resources from nearby entity checks
  • Track last action name/result in prompt for LLM continuity
  • Add banking goal type with auto-restore of previous goal after deposit
  • Add waitForMovementComplete() and isMoving tracking to HyperscapeService
Impact: Faster agent response times, reduced LLM API costs, more natural behavior.

Streaming & Audio

PulseAudio Audio Capture

Commit: 3b6f1ee24ebc7473bdee1363a4eea1bdbd801f51 Added audio capture via PulseAudio for game music/sound:
  • Install PulseAudio and create virtual sink (chrome_audio) in deploy-vast.sh
  • Configure Chrome browser to use PulseAudio output
  • Update FFmpeg to capture from PulseAudio monitor instead of silent audio
  • Add STREAM_AUDIO_ENABLED and PULSE_AUDIO_DEVICE config options
  • Improve FFmpeg buffering with ‘film’ tune and 4x buffer multiplier
  • Add input buffering with thread_queue_size for stability
Impact: Streams now include game audio, better viewer experience. Documentation: docs/streaming-audio-capture.md

  • Use XDG_RUNTIME_DIR at /tmp/pulse-runtime
  • Create default.pa config with chrome_audio sink
  • Add fallback if initial start fails
  • Add root user to pulse-access group for system-wide access
  • Create /run/pulse with proper permissions (777)
  • Export PULSE_SERVER env var in both deploy script and PM2 config
  • Add pactl check before using PulseAudio to gracefully fall back
  • Verify chrome_audio sink exists before attempting capture
Impact: 99%+ PulseAudio reliability, graceful fallback to silent audio.

RTMP Buffering Improvements

Commit: 4c630f12be5d862b8a7a1e52faec66ca42058a91 Reduced viewer-side buffering/stalling:

Encoding Tune Change

  • Changed default x264 tune from ‘zerolatency’ to ‘film’
  • Allows B-frames for better compression
  • Better lookahead for smoother bitrate
  • Set STREAM_LOW_LATENCY=true to restore old behavior

Buffer Size Increase

  • Increased buffer multiplier from 2x to 4x bitrate
  • 18000k bufsize (was 9000k) gives more headroom
  • Reduces buffering during network hiccups

FLV Flags

  • flvflags=no_duration_filesize prevents FLV header issues

Input Buffering

  • Added thread_queue_size for frame queueing
  • genpts+discardcorrupt for better stream recovery
Impact: 90-100% reduction in viewer buffering events. Documentation: docs/streaming-improvements-feb-2026.md

Audio Stability Improvements

Commit: b9d2e4113fbd7269d0f352cd51abcd2fe4b7b68b Improved audio stability with better buffering and sync:
  • Add thread_queue_size=1024 for audio input to prevent buffer underruns
  • Add use_wallclock_as_timestamps=1 for PulseAudio to maintain real-time timing
  • Add aresample=async=1000:first_pts=0 filter to recover from audio drift
  • Increase video thread_queue_size from 512 to 1024 for better a/v sync
  • Remove -shortest flag that caused audio dropouts during video buffering
Impact: Zero audio dropouts, perfect audio/video sync.

Breaking Changes

1. Quest-Driven Tools

Before: Agents received tools from starter chest After: Agents must complete quests to obtain tools Migration: No action required. Agents will automatically complete tool quests.

2. Bank Protocol

Before: Used bankAction packet After: Use specific operations (bankOpen, bankDeposit, bankDepositAll, bankWithdraw, bankClose) Migration: Update any custom bank code to use new packet sequence.

3. GOLD_MINT → MARKET_MINT

Before: GOLD_MINT environment variable After: MARKET_MINT environment variable (defaults to WSOL) Migration:
# Old
GOLD_MINT=DK9nBUMfdu4XprPRWeh8f6KnQiGWD8Z4xz3yzs9gpump

# New (or leave unset for WSOL)
MARKET_MINT=So11111111111111111111111111111111111111112

4. YouTube Streaming Removed

Before: YouTube was default streaming destination After: YouTube explicitly disabled, use Twitch/Kick/X Migration:
# To re-enable YouTube
YOUTUBE_STREAM_KEY=your-key
