+ +// New (0.183.2) +import { atan } from 'three/tsl'; +``` + +**Impact**: Latest Three.js features, improved WebGPU performance and stability. + +### Streaming Pipeline Optimization (March 10, 2026) + +**Change** (Commits c0e7313, 796b61f): Major streaming pipeline overhaul with CDP default, default ANGLE backend, and FFmpeg improvements. + +**Key Changes**: +- **Default Capture Mode**: CDP (Chrome DevTools Protocol) everywhere for reliability +- **Chrome Beta Channel**: Switched from Chrome Unstable to Chrome Beta for better stability +- **ANGLE Backend**: Default ANGLE backend (`--use-angle=default`) for automatic best-backend selection +- **FFmpeg Resolution**: Prefer system ffmpeg (`/usr/bin`, `/usr/local/bin`) over ffmpeg-static to avoid segfaults +- **x264 Tuning**: Default to `zerolatency` tune for live streaming (was `film`) +- **RTMP Muxer**: Changed from `flv` to `fifo` muxer with `drop_pkts_on_overflow=1` to absorb network stalls without blocking encoder +- **GOP Size**: Changed from 30→60 frames (2s at 30fps) per Twitch/YouTube recommendations for stability +- **Playwright Fix**: Block `--enable-unsafe-swiftshader` injection to prevent CPU software rendering +- **Dead Code Removal**: Deleted `dev-final.mjs` (875 lines), removed `SERVER_DEV_LEAN_MODE` system + +**ANGLE Backend Selection**: +```bash +# Linux NVIDIA - RECOMMENDED for production streaming +STREAM_CAPTURE_ANGLE=vulkan +--use-angle=vulkan --enable-features=DefaultANGLEVulkan,Vulkan,VulkanFromANGLE + +# macOS +STREAM_CAPTURE_ANGLE=metal +--use-angle=metal + +# Auto-select (fallback) +STREAM_CAPTURE_ANGLE=default +--use-angle=default +``` + +**Why Vulkan ANGLE on Linux**: ANGLE OpenGL ES (`--use-angle=gl`) fails with "Invalid visual ID" on NVIDIA GPUs. Native Vulkan (`--use-vulkan`) crashes. Only ANGLE's Vulkan backend works reliably for WebGPU streaming on Linux NVIDIA hardware. + +**FFmpeg Improvements**: +```bash +# Resolution order (avoids ffmpeg-static segfaults) +/usr/bin/ffmpeg → /usr/local/bin/ffmpeg → PATH → ffmpeg-static +``` + +**Impact**: More reliable streaming across diverse GPU hardware, lower latency, eliminates FFmpeg segfaults, fewer crashes and rendering artifacts. + +### Physics Optimization for Streaming (March 10, 2026) + +**Change** (Commit c0e7313): Skip client-side PhysX initialization for streaming/spectator viewports. + +**Rationale**: Streaming and spectator clients don't need physics simulation - they only render the world state. + +**Impact**: Faster streaming client startup, reduced memory footprint for spectator views. + +### Service Worker Cache Strategy (March 10, 2026) + +**Change** (Commit 796b61f): Switched Workbox caching from `CacheFirst` to `NetworkFirst` for JS/CSS. + +**Problem**: Stale service worker serving old HTML for JS chunks after rebuild. + +**Solution**: `NetworkFirst` strategy - always fetch latest, fallback to cache. + +**Impact**: Eliminates stale module errors after rebuilds, better dev experience. + +### WebSocket Connection Stability (March 10, 2026) + +**Change** (Commit 3b4dc66): Fixed WebSocket disconnects under load. + +**Impact**: More stable multiplayer connections during high-load scenarios. + +### CDN URL Unification (Commit 2173086) + +**Change**: Replaced `DUEL_PUBLIC_CDN_URL` with unified `PUBLIC_CDN_URL` environment variable. + +**Rationale**: Simplifies CDN configuration by using a single environment variable across all contexts instead of separate duel-specific and general CDN URLs. + +**Configuration**: +```bash +# Old (deprecated) +DUEL_PUBLIC_CDN_URL=https://assets.hyperscape.club + +# New (unified) +PUBLIC_CDN_URL=https://assets.hyperscape.club +``` + +**Impact**: +- Cleaner environment variable naming +- Consistent CDN URL across client, server, and streaming contexts +- Reduces configuration complexity + +### Dependency Updates (March 10, 2026) + +**Major Updates**: +- **Capacitor**: 7.6.0 → 8.2.0 (Android, iOS, Core)

platform features (Capacitor 8.2.0) +- Improved icon library with new icons +- Better BVH performance for collision detection +- Latest linting rules and TypeScript support +- Bug fixes and security updates + +### SSH Keepalive & Maintenance Timeout (March 13, 2026) + +**Change** (PR #1028, Commit fb0d154): Added strict SSH keepalive settings and reduced maintenance mode timeout for faster deployments. + +**SSH Keepalive Configuration**: +- Added `ServerAliveInterval=15` and `ServerAliveCountMax=3` to SSH commands in `.github/workflows/deploy-vast.yml` +- Prevents SSH connection drops during long-running maintenance mode operations +- SSH will detect dead connections within 45 seconds (15s × 3 retries) + +**Maintenance Mode Timeout**: +- Reduced timeout from 300 seconds (5 minutes) to 30 seconds +- Reduced curl timeout from 600 seconds to 30 seconds +- Faster deployment cycles when waiting for current duel to complete + +**Configuration**: +```bash +# SSH keepalive flags\nssh -o ServerAliveInterval=15 -o ServerAliveCountMax=3\n\n# Maintenance mode API call\ncurl -X POST 'http://127.0.0.1:5555/admin/maintenance/enter' \\\n -d '{\"reason\":\"deployment\",\"timeoutMs\":30000}' \\\n --max-time 30\n```\n\n**Impact**: More reliable SSH connections during deployments, faster deployment cycles, prevents connection drops during maintenance mode.\n\n### Deployment Fixes (March 11, 2026)\n\n**Change** (Commits a65a308, 9e6f5bb): Fixed SSH session timeout and orphaned process deadlocks during Vast.ai deployments. + +**Problem 1 - SSH Timeout**: Background processes (Xvfb, socat) were keeping SSH session file descriptors open, causing `appleboy/ssh-action` to hang for 30 minutes until `command_timeout` killed it - even though deployment completed in ~1 minute. + +**Fix 1**: Added `disown` after each background process in `scripts/deploy-vast.sh` to detach them from the shell's job table, allowing SSH to exit cleanly. + +**Problem 2 - Orphaned Bun Processes**: PM2 `kill` command was failing to terminate orphaned bun child processes (game server instances), causing them to hold database connections and deadlock subsequent deployments. + +**Fix 2**: Added explicit `pkill` commands in `scripts/deploy-vast.sh` to kill orphaned bun server processes before starting new deployment: +```bash +# Kill ORPHANED bun child processes that pm2 kill failed to terminate +pkill -f "bun.*packages/server.*dist/index.js" || true +pkill -f "bun.*packages/server.*start" || true +pkill -f "bun.*dev-duel.mjs" || true +pkill -f "bun.*preview.*3333" || true +``` + +**Impact**: +- Deployment completes in ~1 minute instead of hanging for 30 minutes +- Eliminates database connection deadlocks from ghost game servers +- CI/CD pipeline runs faster and more reliably +- No more false timeout failures or deployment hangs + +**CI Test Filter Updates** (Commit d7a7995): Updated Turbo test filter to exclude deleted packages from main branch. + +### Procgen Package Circular Dependency Fix (March 12, 2026) + +**Change** (PR #1018): Resolved circular dependency between `@hyperscape/shared` and `@hyperscape/procgen`. + +**Problem**: `procgen` imported `TileCoord` type from `shared`, while `shared` imported procgen for terrain generation, creating a circular dependency. + +**Fix**: Defined `TileCoord` interface locally in `packages/procgen/src/building/viewer/index.ts` to break the cycle. + +**Impact**: Cleaner package boundaries, procgen can now build without TypeScript errors. + +See CLAUDE.md for complete documentation. diff --git a/API-ARTISAN-SKILLS.md

This was particularly problematic for canyon biome which relies on up-to-date manifest data. + +**Solution**: +```typescript +// Client-side cache busting (packages/shared/src/data/DataManager.ts) +const cacheBuster = `?v=${Date.now()}`; +const manifestUrl = `${CDN_URL}/manifests/${filename}${cacheBuster}`; + +// Server-side cache busting (scripts/upload-to-r2.sh) +aws s3 cp "manifests/${file}" "s3://${BUCKET}/manifests/${file}?v=$(date +%s)" \ + --endpoint-url "${ENDPOINT}" \ + --content-type "application/json" +``` + +**Deployment Workflow Improvements**: +- **Prevent Submodule Overwrite**: `scripts/upload-to-r2.sh` now skips `assets/manifests` directory during upload +- **Ensure Manifests Exist**: GitHub Actions runs `ensure-assets.mjs` before R2 upload +- **Removed Broken CORS Config**: R2 CORS is now configured via Cloudflare dashboard (removed failing CLI step) +- **Wrangler R2 Fix** (Commit 94e3a1d): Added `--remote` flag to `wrangler r2 object put` in `.github/workflows/deploy-cloudflare.yml` to target remote Cloudflare bucket instead of local +- **Vast.ai Asset Refresh** (Commit ef42c3d): Deployment script now forcefully removes cached `packages/server/world/assets` folder before `bun install` to ensure latest manifests are fetched from Git LFS +- **Docker Cache Invalidation** (Commits a52294, 207fd8a): Added cache-busting steps to prevent Docker build cache from storing stale `biomes.json` and other manifest files + +**Files Changed**: +- `packages/shared/src/data/DataManager.ts` - Client-side cache busting +- `scripts/upload-to-r2.sh` - Server-side cache busting and submodule skip +- `.github/workflows/deploy-r2.yml` - Added ensure-assets step +- `.github/workflows/deploy-cloudflare.yml` - Added `--remote` flag to wrangler +- `scripts/deploy-vast.sh` - Force fresh asset fetch with `rm -rf packages/server/world/assets` +- `Dockerfile.server` - Added `rm -rf packages/server/world/assets` before `ensure-assets.mjs` + +**Impact**: +- Eliminates stale manifest issues across all deployment targets (Railway, Vast.ai, Cloudflare) +- Ensures clients always fetch latest game data +- Prevents canyon biome errors from outdated manifests +- No manual CDN cache purging required +- Docker builds always use fresh manifests from Git LFS + +### Manifest Embedding in Docker (March 13, 2026) + +**Change** (Commit efa8021): Server Docker image now embeds manifests to bypass CDN and fix canyon biome errors. + +**Problem**: Server was fetching manifests from CDN at runtime, which could fail if CDN was unavailable or manifests were stale. Canyon biome was failing due to missing manifest data. + +**Fix**: +- Manifests are now embedded directly in the Docker image at build time +- Server reads manifests from local filesystem instead of CDN +- Ensures manifests are always available and match the deployed code version + +**Files Changed**: +- `Dockerfile.server` - Added COPY step for manifests from builder stage +- Server reads from `packages/server/world/assets/manifests/` (embedded in image) + +**Docker Build Process**: +```dockerfile +# Builder stage +RUN node scripts/ensure-assets.mjs # Fetch manifests +COPY --from=builder /app/packages/server/world ./packages/server/world # Runtime stage +``` + +**Impact**: More reliable server startup, eliminates CDN dependency for manifests, fixes canyon biome loading errors. + +### Workbox Service Worker Fix (March 13, 2026) + +**Change** (Commit 9312a96): Inline workbox runtime to prevent MIME type errors on PWA update. + +**Problem**: Service worker was failing to update due to MIME type errors when loading workbox runtime from external CDN. + +**Fix**: Workbox runtime is now inlined directly into the service worker bundle instead of being loaded from external source. + +**Files Changed**: +- `packages/client/vite.config.ts` - Updated Workbox plugin configuration + +**Configuration**: +```typescript +// packages/client/vite.config.ts +workbox: { + inlineWorkboxRuntime: true, // Inline instead of loading from CDN + // ... rest of config +} +``` + +**Impact**: Eliminates service worker update failures, more reliable PWA updates, better offline support. + +### Tree Shader Lighting Fix (March 12, 2026) + +**Change** (PR #1022): Fixed tree lighting to use vertex sphere normals instead of normal maps. + +**Problem**: Tree models have sphere normals baked into the vertex normal attribute for volumetric foliage shading, but the shader was using `normalWorld` which goes through the TSL normal map pipeline, ignoring the correct vertex data. + +**Solution**: +```typescript +// packages/shared/src/systems/shared/world/GPUMaterials.ts +// Old (incorrect - uses normal map pipeline) +const N = normalize(normalWorld); + +// New (correct - uses vertex sphere normals) +const N = normalize(mul(modelNormalMatrix, normalLocal)); +``` + +**Night Lighting Improvements**: +- Uniform `nightDim` multiplier maintains consistent ~1.35x lit-to-shadow ratio +- SSS (subsurface scattering), edge brightening, and saturation boost scale with `dayFactor` +- Night foliage stays muted and cool-toned +- Eliminates 4.8x contrast variance between day and night + +**Impact**: Correct volumetric foliage lighting, consistent tree appearance across day/night cycle. + +### Biome Terrain Generation & Quadtree LOD (March 12, 2026) + +**Change** (PR #1018): Merged biome-based terrain generation with hierarchical quadtree LOD system. + +#### TerrainQuadTree +Hierarchical LOD system for infinite terrain rendering: +- **Dynamic Splitting**: Chunks split/unsplit based on camera distance +- **LOD Levels**: 5 levels (depth 0-4), from 1600m root chunks to 100m leaf chunks +- **Uniform Resolution**: 32x32 vertices per chunk at all LOD levels +- **Skirt Geometry**: 15m drop to hide LOD seams +- **Client-Only**: Visual system only - server still uses flat 100m tile grid + +**Configuration** (`packages/shared/src/systems/shared/world/TerrainQuadTree.ts`): +```typescript +{ + minSize: 100, // Smallest chunk (matches TILE_SIZE) + maxDepth: 4, // Max subdivision depth + splitRatio: 1.5, // Split when distance < size * splitRatio + unsplitMultiplier: 1.2, // Prevents thrashing at LOD boundaries + resolution: 32, // Uniform vertex resolution + skirtDrop: 15, // Skirt depth in meters +} +``` + +**Performance Optimizations**: +- Numeric grid coordinates instead of string keys (eliminates per-frame string allocation) +- Structural dirty flag to skip neighbor resolution when tree is stable +- Lazy terrain generation (only when all 4 neighbors are resolved) + +#### GLBTreeBatchedInstancer +Multi-variant tree rendering with BatchedMesh: +- **One BatchedMesh per material slot per LOD** - minimal draw calls +- **Texture Fingerprinting**: Automatic material slot matching across variants +- **LOD Switching**: Smooth transitions between LOD0/LOD1/LOD2 based on distance +- **Depleted State**: Separate geometry for chopped trees (stumps) +- **Highlight Support**: Per-instance color tinting for interaction feedback + +**Key Features**: +- Supports trees with multiple model variants (e.g., oak_tree_1.glb, oak_tree_2.glb) +- Deterministic fingerprinting prevents silent variant matching failures +- Hysteresis on LOD transitions (0.81x multiplier) prevents flickering + +**Usage**: +```typescript +await addInstance( + 'oak', // Tree type + ['oak_1.glb', 'oak_2.glb'], // Variant paths + 0, // Variant index + entityId, + position, + rotation, + scale, + 'oak_stump.glb', // Depleted model (optional) + 0.8 // Depleted scale (optional) +); +``` + +#### Biome System +Terrain generation now uses biome-specific parameters: +- **3 Biomes**: Forest, Canyon, Tundra (defined in `TerrainBiomeTypes.ts`) +- **2 Landscape Types**: Mountain, Pond (defined in `TerrainHeightParams.ts`) +- **Per-Biome Tree Distribution**: Each biome has unique tree types, densities, and placement rules +- **TreeId Enum**: Centralized tree type identifiers replacing magic strings +- **Batched Entity Spawning**: Reduces network overhead by batching all entities for a tile into single packet + +**Files**: +- `packages/shared/src/systems/shared/world/TerrainBiomeTypes.ts` - Biome definitions and per-biome tree configs +- `packages/shared/src/systems/shared/world/TerrainHeightParams.ts` - Landscape feature definitions +- `packages/shared/src/systems/shared/world/BiomeResourceGenerator.ts` - Resource placement logic +- `packages/shared/src/constants/TreeTypes.ts` - TreeId enum (single source of truth for tree type identifiers) + +**TreeId Enum Pattern**: +All tree types are now defined using the `TreeId` enum instead of magic strings: +```typescript +// packages/shared/src/constants/TreeTypes.ts +export enum TreeId { + Oak = "tree_oak", + Willow = "tree_willow", + Maple = "tree_maple", + // ... etc +} + +// Usage in biome configs +const FOREST_TREE_CONFIG: BiomeTreeConfig = { + trees: { + [TreeId.Oak]: { weight: 20, maxHeight: 30 }, + [TreeId.Maple]: { weight: 40, maxHeight: 30 }, + }, + // ... +}; +``` + +**Tree Placement Rules**: +Each tree type can have biome-specific placement constraints: +- `weight` - Relative spawn probability (higher = more common) +- `minHeight` / `maxHeight` - Elevation constraints (world units) +- `waterAffinity` - Preference for water-adjacent placement (0-1, where 1 = only spawns near water) +- `waterProximityHeight` - Max height above water to consider "near water" (meters) +- `avoidsWaterBelow` - Reject placement if below this height above water threshold (meters) +- `maxSlope` - Maximum terrain slope for placement (gradient, e.g., 1.5 = 56° max slope) + +**Example Biome Config** (from `packages/shared/src/systems/shared/world/TerrainBiomeTypes.ts`): +```typescript +const FOREST_TREE_CONFIG: BiomeTreeConfig = { + enabled: true, + trees: { + [TreeId.Knotwood]: { weight: 40, maxHeight: 30 }, + [TreeId.Oak]: { weight: 20, maxHeight: 30 }, + [TreeId.Birch]: { weight: 20, maxHeight: 30 }, + [TreeId.Maple]: { weight: 40, maxHeight: 30 }, + [TreeId.Fir]: { weight: 15, maxHeight: 30 }, + [TreeId.Pine]: { weight: 15, maxHeight: 30 }, + [TreeId.ChinaPine]: { weight: 15, minHeight: 30, maxHeight: 60 }, + [TreeId.Bamboo]: { weight: 15, minHeight: 35 }, + }, + density: 15, + minSpacing: 12, + clustering: false, + scaleVariation: [0.8, 1.2], + maxSlope: 1.5, +}; + +const CANYON_TREE_CONFIG: BiomeTreeConfig = { + enabled: true, + trees: { + [TreeId.Cactus]: { weight: 20, avoidsWaterBelow: 3 }, + [TreeId.Dead]: { weight: 20, minHeight: 20 }, + [TreeId.Palm]: { + weight: 20, + waterAffinity: 0.3, + waterProximityHeight: 9, + maxHeight: 15, + }, + [TreeId.Coconut]: { + weight: 10, + waterAffinity: 0.6, + waterProximityHeight: 9, + maxHeight: 15, + }, + }, + density: 15, + minSpacing: 18, + clustering: false, + scaleVariation: [0.7, 1.3], + maxSlope: 2.0, +}; + +const TUNDRA_TREE_CONFIG: BiomeTreeConfig = { + enabled: true, + trees: { + [TreeId.WindPine]: { weight: 40, minHeight: 15 }, + [TreeId.Fir]: { weight: 30, minHeight: 10 }, + [TreeId.Pine]: { weight: 25, minHeight: 8 }, + [TreeId.Birch]: { weight: 10 }, + }, + density: 10, + minSpacing: 12, + clustering: false, + scaleVariation: [0.6, 1.0], + maxSlope: 1.5, +}; +``` + +**Impact**: Infinite terrain rendering with dynamic LOD, biome-specific visuals, improved performance through reduced draw calls and smarter chunk management. + +### Admin Live Controls & Maintenance Mode (March 12, 2026) + +**Change** (PR #1015): Added admin dashboard with live controls, maintenance mode, and log streaming. + +#### Maintenance Mode System +Graceful server pause/resume for zero-downtime deployments: +- **Endpoints**: + - `POST /admin/maintenance/enter` - Pause game after current duel + - `POST /admin/maintenance/exit` - Resume game + - `GET /admin/maintenance/status` - Check maintenance state +- **Safe-to-Deploy Flag**: Prevents restarts during active duels +- **Market Pause**: Automatically pauses betting markets during maintenance + +**Implementation**: +```typescript +// packages/server/src/startup/maintenance-mode.ts +export interface MaintenanceState { + active: boolean; + enteredAt: number | null; + reason: string | null; + safeToDeploy: boolean; + currentPhase: string | null; + marketStatus: string; + pendingMarkets: number; +} +``` + +#### Live Controls Dashboard +Real-time admin panel (`packages/client/src/screens/AdminLiveControls.tsx`): +- **HLS Stream Preview**: Embedded video player for live stream monitoring +- **Server Controls**: Pause/resume game, restart process +- **Live Logs**: 1000-entry ring buffer with auto-refresh (3s interval) +- **Status Display**: Maintenance state, viewer count, current phase + +**CSS Layout Improvements** (PR #1019): +- Fixed scrolling issues in admin panels with proper flexbox layout +- Added `overflow: hidden` on `.admin-content` with `overflow-y: auto` on inner containers +- Proper `min-height: 0` overrides for nested flex containers to enable scroll containment +- Eliminated layout thrashing and scroll conflicts in admin dashboard + +**Admin API Endpoints**: +- `GET /admin/logs` - Fetch recent server logs from

banner (`packages/client/src/components/common/MaintenanceBanner.tsx`): +- Polls `/health` endpoint every 5s +- Displays red banner when `maintenanceMode: true` +- Visible across all client screens (game, admin, leaderboard, etc.) + +#### Logger Ring Buffer +In-memory log storage (`packages/server/src/systems/ServerNetwork/services/Logger.ts`): +- **Capacity**: 1000 most recent log entries +- **Levels**: DEBUG, INFO, WARN, ERROR +- **Structure**: `{ timestamp, level, system, message, data }` +- **API**: `GET /admin/logs` returns full buffer + +**Configuration**: +```bash +# ecosystem.config.cjs +ORACLE_SETTLEMENT_DELAY_MS=7000 # Delay oracle publish to sync with stream +``` + +**Impact**: Zero-downtime deployments, better operational visibility, safer server restarts. + +### Oracle Settlement Delay & Stream Sync (March 12, 2026) + +**Change** (Commit 38c8c89): Added configurable settlement delay to sync oracle publishing with stream delivery. + +**Problem**: Oracle was publishing duel outcomes immediately after resolution, but stream viewers were still watching the duel (7-10s behind live). + +**Solution**: +- Added `settlementDelayMs` to `DuelArenaOracleConfig` +- Default: 7000ms (7 seconds) +- Delays `publishAcrossTargets()` call after duel resolution + +**Configuration**: +```bash +# ecosystem.config.cjs or .env +ORACLE_SETTLEMENT_DELAY_MS=7000 # Match typical stream latency +``` + +**Code**: +```typescript +// packages/server/src/oracle/DuelArenaOraclePublisher.ts +if (this.config.settlementDelayMs > 0) { + await new Promise((resolve) => +

UX for betting/spectating. + +### Agent Autonomous Behavior Restoration (March 12, 2026) + +**Change** (Commit 82a5365): Fixed agent T-pose and re-enabled autonomous behavior between duels. + +**Fixes**: +- **Physics Null Guards**: Added null checks in `RigidBody.ts` and `Collider.ts` for stream mode viewports where physics system is removed +- **Autonomous Behavior**: Re-enabled mining, chopping, fishing for duel bot agents between duels (was suppressed) +- **Post-Duel Roaming**: Relaxed restore position from 120-unit lobby radius to 2000-unit world boundary +- **Model Provider Diversity**: Switched from ElizaCloud to direct Anthropic/Groq providers (PR #1018) + - Interleaved provider selection ensures diversity (Anthropic → Groq → Anthropic → Groq...) + - Models: Claude Sonnet 4.6, Llama 4 Scout, Claude Opus 4.6, Llama 4 Maverick, Claude Haiku 4.5, Llama 3.3 70B, Kimi K2, Qwen 3 30B + - Updated `@elizaos/plugin-elizacloud` to `alpha` tag for compatibility +- **Bank State Request**: Request bank state on player spawn so goal planner has item data + +**Code Changes**: +```typescript +// packages/shared/src/nodes/RigidBody.ts +if (!this.world.physics) return; // Null guard for stream mode + +// packages/server/src/eliza/ElizaDuelBot.ts +// Removed dedicatedDuelBot gates that killed all open-world autonomy +// shouldRunOpenWorldAutonomy() now always returns true + +// packages/plugin-hyperscape/src/services/HyperscapeService.ts +private shouldRunOpenWorldAutonomy(): boolean { + // Duel bots should perform autonomous activities (mining, chopping, fishing) + // between duels to make the world feel alive + return true; +} +``` + +**Impact**: Agents now behave naturally between duels, no more T-pose in stream mode, better goal planning with bank awareness. + +### Streaming Pipeline Improvements (March 10-12, 2026) + +**Frame Pacing Fix** (Commits 522fe37, e2c9fbf): +- **Problem**: CDP screencast delivering ~60fps to FFmpeg expecting 30fps, causing buffer buildup +- **Fix**: Reverted `everyNthFrame` to 1 (Xvfb compositor runs at 30fps, not 60fps) +- **Resolution**: Default changed from 1920x1080→1280x720 to match capture viewport +- **Impact**: Eliminates stream buffering, smoother playback + +**GOP Size Change** (Commit 38c8c89): +- Changed from 30→60 frames (1s→2s at 30fps) +- Recommended by Twitch/YouTube for stability +- Tradeoff: Increased tune-in latency for better stream stability + +**RTMP Muxer** (Commit 38c8c89): +- Changed from `flv` to `fifo` muxer +- `drop_pkts_on_overflow=1` absorbs network stalls without blocking encoder +- Better resilience to network jitter + +**Configuration**: +```bash +# ecosystem.config.cjs +STREAM_CAPTURE_WIDTH=1280 +STREAM_CAPTURE_HEIGHT=720 +STREAM_CAPTURE_MODE=cdp # CDP (default) or webcodecs +STREAM_CAPTURE_ANGLE=vulkan # ANGLE backend (vulkan, metal, default) +``` + +### Solana Oracle IDL Type Formatting (March 13, 2026) + +**Change** (Commits in `packages/duel-oracle-solana/src/generated/`): Reformatted Solana oracle IDL types from JSON-style to TypeScript-style object literals. + +**Technical Details**: +```typescript +// Old (JSON-style) +export const FIGHT_ORACLE_IDL = { + "address": "6Tx7s2UG4maFWakRFVi4GeecXJYyBXQF8f2vJdQShSpV", + "metadata": { + "name": "fight_oracle", + // ... + } +} + +// New (TypeScript-style) +export const FIGHT_ORACLE_IDL = { + address: "6Tx7s2UG4maFWakRFVi4GeecXJYyBXQF8f2vJdQShSpV", + metadata: { + name: "fight_oracle", + // ... + } +} as const; +``` + +**Files Changed**: +- `packages/duel-oracle-solana/src/generated/fightOracleIdl.ts` +- `packages/duel-oracle-solana/src/generated/fightOracleTypes.ts` +- `packages/duel-oracle-solana/src/generated/fight_oracle.ts` + +**Impact**: Better TypeScript type inference, cleaner code style, improved IDE autocomplete, no functional changes. + +### Solana Oracle Error Handling Improvements (March 12, 2026) + +**Change** (PR #1019): Enhanced Solana transaction error messages with detailed log extraction. + +**Problem**: Solana `SendTransactionError` messages were unhelpful, showing generic "Catch the `SendTransactionError` and call `getLogs()` on it for full details" instead of actual error details. + +**Solution**: +```typescript +// packages/server/src/oracle/DuelArenaOraclePublisher.ts +if (error && typeof error === "object" && "logs" in error) { + const logs = (error as any).logs; + if (Array.isArray(logs)) { + // Strip unhelpful boilerplate + errorMessage = errorMessage + .replace(/Catch the `SendTransactionError`.*$/g, "") + .trim(); + + // Append actual transaction logs + const logsStr = logs.join("\\n "); + errorMessage = `${errorMessage}\\nTransaction Logs:\\n ${logsStr}`; + + // Detect common errors + if (logsStr.includes("insufficient lamports")) { + errorMessage = `Insufficient SOL to pay for transaction rent or fees.\\n${errorMessage}`; + } + } +} +``` + +**Impact**: Significantly improved debuggability for Solana oracle failures, clearer error messages for insufficient SOL and other transaction failures. + +### Deployment Fixes (March 11-13, 2026) + +**Docker Workspace Symlinks** (Commit 7f1af94): +- **Problem**: Docker COPY flattens workspace symlinks, breaking runtime module resolution for externalized packages +- **Fix**: Added `bun install --production` in Docker runtime stage to restore symlinks +- **Impact**: Server can resolve @hyperscape/* workspace packages in production Docker deployments + +**SSH Timeout Fix** (Commit a65a308): +- **Problem**: Background processes (Xvfb, socat) keeping SSH session open, causing 30-minute hangs +- **Fix**: Added `disown` after each background process in `scripts/deploy-vast.sh` +- **Impact**: Deployment completes in ~1 minute instead of hanging for 30 minutes + +**Orphaned Process Cleanup** (Commit 9e6f5bb): +- **Problem**: PM2 `kill` failing to terminate orphaned bun child processes, causing database deadlocks +- **Fix**: Added explicit `pkill` commands before deployment: + ```bash + pkill -f "bun.*packages/server.*dist/index.js" || true + pkill -f "bun.*packages/server.*start" || true + pkill -f "bun.*dev-duel.mjs" || true + pkill -f "bun.*preview.*3333" || true + ``` +- **Impact**: Eliminates database connection deadlocks from ghost game servers + +**Docker Workspace Symlinks** (Commit 7f1af94): +- **Problem**: Docker COPY flattens workspace symlinks, breaking runtime module resolution +- **Fix**: Added `bun install --production` in Docker runtime stage to restore

**EquipmentVisualSystem.test.ts**: Changed to `vi.spyOn()` with fallback to real `getItem()` data +- **MobRightClickAttack.test.ts**: Added proper window mock cleanup with try/finally guards +- **GravestoneLootSystem.test.ts**: Namespaced test items with `grave_` prefix to avoid registry collisions + +**Testing Strategy**: +- WebGPU-dependent packages (`impostor`, `client`) require local

features: + +```bash +-thread_queue_size 1024 \ +-use_wallclock_as_timestamps 1 \ +-f pulse \ +-ac 2 \ +-ar 44100 \ +-i chrome_audio.monitor +``` + +**Parameters:** +- `thread_queue_size 1024` - Buffer 1024 audio packets to prevent underruns +- `use_wallclock_as_timestamps 1` - Use wall clock for accurate timing +- `f pulse` - PulseAudio input format +- `ac 2` - 2 audio channels (stereo) +- `ar 44100` - 44.1kHz sample rate +- `i chrome_audio.monitor` - Capture from monitor source + +### Audio Filter + +Async resampling recovers from audio drift: + +```bash +-af aresample=async=1000:first_pts=0 +``` + +**Parameters:** +- `async=1000` - Resample if drift exceeds 1000 samples (22ms at 44.1kHz) +- `first_pts=0` - Start PTS at 0 for consistent timing + +This prevents audio dropouts when video/audio streams desync. + +### Audio Encoding + +```bash +-c:a aac \ +-b:a 128k \ +-ar 44100 \ +-flags +global_header +``` + +**Parameters:** +- `c:a aac` - AAC audio

improvements made to Hyperscape's RTMP broadcasting system in February 2026. + +## Overview + +Hyperscape's streaming system has been significantly enhanced with better buffering, audio capture, multi-platform support, and improved stability. These changes address viewer-side buffering issues, audio dropouts, and stream reliability. + +## Major Changes + +### 1. Audio Capture via PulseAudio + +**What Changed**: Streams now include game audio (music and sound effects) instead of silent audio. + +**Implementation**: +- PulseAudio virtual sink (`chrome_audio`) captures browser audio +- FFmpeg reads from monitor device (`chrome_audio.monitor`) +- Async resampling prevents audio drift +- Graceful fallback to silent audio if PulseAudio unavailable + +**Configuration**: +```bash +# packages/server/.env +STREAM_AUDIO_ENABLED=true +PULSE_AUDIO_DEVICE=chrome_audio.monitor +PULSE_SERVER=unix:/tmp/pulse-runtime/pulse/native +``` + +**See**: [docs/streaming-audio-capture.md](streaming-audio-capture.md) for full setup guide. + +### 2. Improved RTMP Buffering + +**Problem**: Viewers experienced frequent buffering and stalling. + +**Solution**: Changed encoding settings for smoother playback: + +#### Encoding Tune Change + +**Before**: `zerolatency` tune (minimal buffering, unstable bitrate) +**After**: `film` tune (B-frames enabled, better compression, smoother bitrate) + +```bash +# Old (zerolatency) +-tune zerolatency + +# New (film) +-tune film +``` + +**Restore old behavior**: +```bash +STREAM_LOW_LATENCY=true +``` + +#### Buffer Size Increase + +**Before**: 2x bitrate (9000k buffer for 4500k bitrate) +**After**: 4x bitrate (18000k buffer for 4500k bitrate) + +```bash +# Old +-bufsize 9000k + +# New +-bufsize 18000k +``` + +**Impact**: More headroom during network hiccups, reduces buffering events. + +#### Input Buffering + +Added thread queue size for frame queueing: + +```bash +# Video input buffering +-thread_queue_size 1024 + +# Audio input buffering +-thread_queue_size 1024 +``` + +**Impact**: Prevents frame drops during CPU spikes. + +#### FLV Flags + +Added FLV-specific flags for RTMP stability: + +```bash +-flvflags no_duration_filesize +``` + +**Impact**: Prevents FLV header issues that could cause stream interruptions. + +### 3. Audio Stability Improvements + +**Problem**: Intermittent audio dropouts during video buffering. + +**Solutions**: + +#### Wall Clock Timestamps + +```bash +-use_wallclock_as_timestamps 1 +``` + +Maintains accurate audio timing using system clock instead of stream timestamps. + +#### Async Resampling + +```bash +-aresample async=1000:first_pts=0 +``` + +Recovers from audio drift when it exceeds 22ms (1000 samples at 44.1kHz). + +#### Removed -shortest Flag + +**Before**: `-shortest` flag caused audio to stop when video buffered +**After**: Flag removed, both streams continue independently + +**Impact**: Audio no longer drops out during temporary video buffering. + +### 4. Multi-Platform Streaming + +**What Changed**: Default streaming destinations updated. + +#### Removed +- **YouTube** - Explicitly disabled (set `YOUTUBE_STREAM_KEY=""`) + +#### Active Platforms +- **Twitch** - Primary platform (lower latency) +- **Kick** - Uses RTMPS with IVS endpoint +- **X (Twitter)** - RTMP streaming + +**Configuration**: +```bash +# packages/server/.env + +# Twitch +TWITCH_STREAM_KEY=live_123456789_abcdefghij + +# Kick (RTMPS) +KICK_STREAM_KEY=sk_us-west-2_... +KICK_RTMP_URL=rtmps://fa723fc1b171.global-contribute.live-video.net/app + +# X/Twitter +X_STREAM_KEY=your-x-stream-key +X_RTMP_URL=rtmp://sg.pscp.tv:80/x +``` + +**Kick URL Fix**: Corrected from `rtmp://ingest.kick.com` to proper IVS endpoint. + +### 5.

CDP Stall Threshold + +**Increased**: 2 → 4 intervals (60s → 120s before restart) + +```typescript +// packages/server/src/streaming/browser-capture.ts +const CDP_STALL_THRESHOLD = 4; // Was: 2 +``` + +**Rationale**: 2-interval threshold caused false restarts during legitimate pauses (loading screens, scene transitions). 4 intervals provides better tolerance for temporary stalls while still detecting real hangs. + +**Impact**: +- Fewer false restarts +- More stable long-running streams +- Better handling of scene complexity spikes + +### 2. Soft CDP Recovery + +**Added**: Restart screencast without browser/FFmpeg teardown + +```typescript +// Try soft recovery first (no stream gap) +await this.restartScreencast(); + +// Only do full restart if soft recovery fails +if (stillStalled) { + await this.fullRestart(); +} +``` + +**Benefits**: +- No stream interruption during recovery +- Faster recovery (no browser restart overhead) +- Preserves browser state (cookies, localStorage) + +**Fallback**: Full restart if soft recovery fails after 3 attempts + +### 3. FFmpeg Restart Attempts + +**Increased**: 5 → 8 attempts + +```typescript +const MAX_RESTART_ATTEMPTS = 8; // Was: 5 +``` + +**Rationale**: FFmpeg can fail transiently due to: +- Network hiccups +- RTMP server temporary unavailability +- Encoder initialization delays + +8 attempts provides better resilience without infinite retry loops. + +### 4. Capture Recovery Max Failures + +**Increased**: 2 → 4 failures before full teardown + +```typescript +const CAPTURE_RECOVERY_MAX_FAILURES = 4; // Was: 2 +``` + +**Rationale**: Allows more soft recovery attempts before giving up and doing full browser/FFmpeg restart. + +### 5. WebGPU Best-Effort Initialization + +**Added**: Retry with default limits if GPU rejects custom limits + +```typescript +// Try with custom limits first +try { + const adapter = await navigator.gpu.requestAdapter(); + const device = await adapter.requestDevice({ + requiredLimits: { + maxTextureArrayLayers: 2048 // Custom limit + } + }); +} catch (error) { + // Retry with default limits (no requiredLimits) + const device = await adapter.requestDevice(); +} +``` + +**Rationale**: Some GPUs reject custom limits even if they support the feature. Best-effort approach tries custom limits first, falls back to defaults if rejected. + +**Result**: Always WebGPU (never falls back to WebGL in this path). + +### 6. WebGL Fallback for Streaming + +**Added**: Automatic WebGL fallback when WebGPU fails or is disabled + +```typescript +// packages/shared/src/utils/rendering/RendererFactory.ts +if (forceWebGL || disableWebGPU || !navigator.gpu) { + return createWebGLRenderer(); +} + +try { + return await createWebGPURenderer(); +} catch (error) { + console.warn('WebGPU failed, falling back to WebGL:', error); + return createWebGLRenderer(); +} +``` + +**Query Params**: +- `?page=stream&forceWebGL=1` - Force WebGL +- `?page=stream&disableWebGPU=1` - Disable WebGPU + +**Environment Variable**: +```bash +STREAM_CAPTURE_DISABLE_WEBGPU=true +``` + +**Use Cases**: +- Docker containers (WebGPU often unavailable) +- Vast.ai instances (GPU passthrough issues) +- Headless browsers (software rendering) + +### 7.

These changes ensure stable 24/7 streaming with automatic recovery. + +## Major Improvements + +### 1. PulseAudio Audio Capture + +**What**: Capture game audio (music and sound effects) for streaming. + +**Implementation**: +- User-mode PulseAudio (more reliable than system mode) +- Virtual sink (`chrome_audio`) for audio routing +- Automatic fallback to silent audio if PulseAudio fails +- XDG runtime directory at `/tmp/pulse-runtime` + +**Configuration**: +```bash +# Automatic in deploy-vast.sh +export XDG_RUNTIME_DIR=/tmp/pulse-runtime +export PULSE_SERVER=unix:/tmp/pulse-runtime/pulse/native +``` + +**See**: [docs/streaming-audio-capture.md](streaming-audio-capture.md) + +### 2. DATABASE_URL Persistence + +**Problem**: `DATABASE_URL` was lost during `git reset` operations in deployment. + +**Solution**: Write secrets to `/tmp` before git reset, restore after: + +```bash +# Before git reset +cp /tmp/hyperscape-secrets.env /root/hyperscape/packages/server/.env + +# After git reset +if [ -f "/tmp/hyperscape-secrets.env" ]; then + cp /tmp/hyperscape-secrets.env /root/hyperscape/packages/server/.env +fi +``` + +**Impact**: Database connection survives deployment updates. + +### 3. Database Warmup + +**Problem**: Cold start issues with PostgreSQL connection pool. + +**Solution**: Warmup step after schema push with 3 retry attempts: + +```bash +# Warmup database connection +for i in 1 2 3; do + if bun -e " + const { Pool } = require('pg'); + const pool = new Pool({ connectionString: process.env.DATABASE_URL }); + pool.query('SELECT 1').then(() => { + console.log('DB warmup successful'); + pool.end(); + }); + "; then + break + fi + sleep 3 +done +``` + +**Impact**: Eliminates cold start connection failures. + +### 4. Stream Key Management + +**Problem**: Stale stream keys in environment overrode correct values from secrets. + +**Solution**: Explicit unset and re-export before PM2 start: + +```bash +# Clear stale keys +unset TWITCH_STREAM_KEY X_STREAM_KEY X_RTMP_URL KICK_STREAM_KEY KICK_RTMP_URL +unset YOUTUBE_STREAM_KEY # Explicitly disable + +# Re-source from .env +source /root/hyperscape/packages/server/.env + +# Verify (masked) +echo "TWITCH_STREAM_KEY: ${TWITCH_STREAM_KEY:+***configured***}" +``` + +**Impact**: Correct stream keys always used, no more wrong-platform streaming. + +### 5. YouTube Removal + +**What**: YouTube streaming explicitly disabled from default destinations. + +**Why**: Focusing on Twitch, Kick, and X for lower latency and better live betting experience. + +**Implementation**: +```bash +# Explicitly unset YouTube keys +unset YOUTUBE_STREAM_KEY YOUTUBE_RTMP_STREAM_KEY +export YOUTUBE_STREAM_KEY="" +``` + +**To re-enable**: +```bash +# packages/server/.env +YOUTUBE_STREAM_KEY=your-youtube-key +YOUTUBE_RTMP_URL=rtmp://a.rtmp.youtube.com/live2 +``` + +### 6. Streaming Diagnostics + +**What**: Comprehensive diagnostic output after deployment. + +**Includes**: +- Streaming API state +- Game client status (port 3333) +- RTMP status file +- FFmpeg processes +- PM2 logs (filtered for streaming keywords) + +**Example Output**: +```bash +[deploy] ═══ STREAMING DIAGNOSTICS ═══ +[deploy] Streaming state: {"active":true,"destinations":["twitch","kick","x"]} +[deploy] Game client status: 200 +[deploy] RTMP status: {"twitch":"connected","kick":"connected","x":"connected"} +[deploy] FFmpeg processes: 3 running +[deploy] ═══ END DIAGNOSTICS ═══ +``` + +**Impact**: Faster troubleshooting of streaming issues. + +### 7. Solana Keypair Setup + +**What**: Automated Solana keypair configuration from environment variable. + +**Implementation**: +```bash +# Setup keypair from SOLANA_DEPLOYER_PRIVATE_KEY +if [ -n "$SOLANA_DEPLOYER_PRIVATE_KEY" ]; then + bun run scripts/decode-key.ts +fi +``` + +**Output**: Keypair written to `~/.config/solana/id.json` + +**Impact**: Keeper bot and Anchor tools work without manual keypair setup. + +### 8. Health Checking + +**What**: Wait for server health before considering deployment successful. + +**Implementation**: +```bash +# Wait up to 120 seconds for health check +while [ $WAITED -lt 120 ]; do + HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" \ + "http://localhost:5555/health" --max-time 5) + + if [ "$HTTP_STATUS" = "200" ]; then + echo "Server is healthy!" + break + fi + + sleep 5 + WAITED=$((WAITED + 5)) +done +``` + +**Impact**: Deployment only succeeds if server is actually running and healthy. + +## Deployment Flow + +### Complete Deployment Sequence + +```bash +1.

+description: "Multi-platform RTMP streaming with WebGPU capture" +icon: "video" +--- + +## Overview + +Hyperscape includes a production-ready streaming infrastructure for broadcasting AI vs AI duel arena matches to multiple platforms simultaneously (Twitch, Kick, X/Twitter, YouTube). + +## Architecture + +```mermaid +flowchart LR + A[Game Server] --> B[Stream Entry Point] + B --> C[Chrome CDP Capture] + C --> D[FFmpeg RTMP Bridge] + D --> E[Twitch] + D --> F[Kick] + D --> G[X/Twitter] + D --> H[Custom RTMP] +``` + +### Components + +| Component | Purpose | +|-----------|---------| +| **Stream Entry Point** | Dedicated `stream.html` / `stream.tsx` for optimized capture | +| **CDP Capture** | Chrome DevTools Protocol for frame capture | +| **RTMP Bridge** | FFmpeg multiplexer for multi-platform streaming | +| **Viewer Access Control** | Token-based access for trusted viewers | +| **Stream Destinations** | Auto-detection and management of RTMP endpoints | + +## Stream Entry Points + +### Dedicated Stream Client + +Hyperscape includes dedicated entry points optimized for streaming capture: + +**Files:** +- `packages/client/src/stream.html` - HTML entry point +- `packages/client/src/stream.tsx` - React streaming client +- `packages/client/vite.config.ts` - Multi-page build configuration + +**Features:** +- Optimized for headless browser capture +- Minimal UI overhead +- WebGPU-optimized rendering +- Separate from main game client + +**Access:** +```bash +# Development +http://localhost:3333/?page=stream + +# Production +https://hyperscape.gg/?page=stream +``` + +### Client Viewport Mode Detection + +The `clientViewportMode` utility detects the current rendering mode: + +```typescript +import { clientViewportMode } from '@hyperscape/shared'; + +const mode = clientViewportMode(); +// Returns: 'stream' | 'spectator' | 'normal' +``` + +**Use Cases:** +- Disable UI elements in stream mode +- Optimize rendering for capture +- Enable spectator-specific features + +## Stream Capture + +### Chrome DevTools Protocol (CDP) + +Hyperscape uses CDP for high-performance frame capture: + +**Configuration:** +```bash +# Capture mode +STREAM_CAPTURE_MODE=cdp # cdp (default), mediarecorder, or webcodecs + +# Chrome configuration +STREAM_CAPTURE_HEADLESS=false # false (Xorg/Xvfb), new (headless modes) +STREAM_CAPTURE_CHANNEL=chrome-dev # Use Chrome Dev channel for WebGPU +STREAM_CAPTURE_ANGLE=vulkan # vulkan (default), gl, or swiftshader +STREAM_CAPTURE_EXECUTABLE=/usr/bin/google-chrome-unstable # Explicit Chrome path (optional) + +# Capture quality +STREAM_CDP_QUALITY=80 # JPEG quality for CDP screencast (1-100) +STREAM_FPS=30 # Target frames per second +STREAM_CAPTURE_WIDTH=1280 # Capture resolution width (must be even) +STREAM_CAPTURE_HEIGHT=720 # Capture resolution height (must be even) +STREAM_GOP_SIZE=60 # GOP size in frames (default: 60) +``` + +### WebGPU Buffer Upload Fallback + +Handles `mappedAtCreation` failures gracefully: + +```typescript +// From packages/shared/src/utils/rendering/webgpuBufferUploads.ts +try { + buffer = device.createBuffer({ mappedAtCreation: true, ... }); +} catch (error) { + // Fallback: create unmapped buffer and write data separately + buffer = device.createBuffer({ mappedAtCreation: false, ... }); + device.queue.writeBuffer(buffer, 0, data); +} +``` + +**Impact:** Improves WebGPU stability on various GPU drivers. + +## RTMP Streaming + +### Stream Destinations + +Hyperscape supports multiple RTMP destinations with auto-detection: + +**Supported Platforms:** +- Twitch +- Kick (RTMPS) +- X/Twitter +- YouTube (deprecated) +- Custom RTMP servers + +**Auto-Detection:** +```bash +# Stream destinations auto-detected from configured keys +# Uses || logic: TWITCH_RTMP_STREAM_KEY || TWITCH_STREAM_KEY + +# Twitch +TWITCH_RTMP_STREAM_KEY=live_123456789_abcdefghij +TWITCH_RTMP_URL=rtmp://live.twitch.tv/app # Optional override + +# Kick (RTMPS)

Custom RTMP +CUSTOM_RTMP_NAME=Custom +CUSTOM_RTMP_URL=rtmp://your-server/live +CUSTOM_STREAM_KEY=your-key +``` + +**Explicit Destination Control:** +```bash +# Override auto-detection +STREAM_ENABLED_DESTINATIONS=twitch,kick,x +``` + +### FFmpeg RTMP Bridge + +The RTMP bridge multiplexes a single stream to multiple destinations: + +**Features:** +- Single encode, multiple outputs (tee muxer) +- Per-destination stream keys +- Automatic reconnection +- Health monitoring + +**Configuration:** +```bash +# RTMP Bridge Settings +RTMP_BRIDGE_PORT=8765 +GAME_URL=http://localhost:3333/?page=stream + +# Optional local HLS output +HLS_OUTPUT_PATH=packages/server/public/live/stream.m3u8 +HLS_SEGMENT_PATTERN=packages/server/public/live/stream-%09d.ts

+## Viewer Access Control + +### Streaming Viewer Access Tokens + +Secure access control for live streaming viewers: + +**Configuration:** +```bash +# Optional secret token for trusted viewers +STREAMING_VIEWER_ACCESS_TOKEN=replace-with-random-secret-token +``` + +**Access Levels:** +1. **Loopback Viewers**: Always allowed (localhost connections) +2. **Trusted Viewers**: Require access token +3. **Public Viewers**: Subject to public delay + +**Implementation:** +```typescript +// From packages/server/src/streaming/stream-viewer-access-token.ts +export function isAuthorizedStreamViewer( + request: FastifyRequest, + token?: string +): boolean { + // Loopback always allowed + if (isLoopbackRequest(request)) return true; + + // Check access token + const configuredToken = process.env.STREAMING_VIEWER_ACCESS_TOKEN; + if (!configuredToken) return false; + + return token === configuredToken; +} +``` + +**Usage:** +```bash +# Connect with access token +ws://localhost:5555/ws?viewerToken=your-secret-token +``` + +### Public Delay + +Configure delay for public streaming viewers: + +```bash +# Canonical output platform for timing defaults +STREAMING_CANONICAL_PLATFORM=youtube # youtube | twitch | hls + +# Override delay (milliseconds) +STREAMING_PUBLIC_DELAY_MS=15000 # Default varies by platform +``` + +**Platform Defaults:** +- YouTube: 15000ms (15 seconds) +- Twitch: 12000ms (12 seconds) +- HLS: 4000ms (4 seconds) + +## Deployment + +### Vast.ai Deployment + +Enhanced Vast.ai deployment with remote database support: + +**Auto-Detection:** +```bash +# deploy-vast.sh auto-detects remote database mode +# Checks for DATABASE_URL in environment +# Sets USE_LOCAL_POSTGRES=false when remote database detected +``` + +**Stream Key Management:** +```bash +# Explicitly unset and re-export stream keys before PM2 start +unset TWITCH_STREAM_KEY X_STREAM_KEY X_RTMP_URL KICK_STREAM_KEY KICK_RTMP_URL +source /root/hyperscape/packages/server/.env +bunx pm2 start ecosystem.config.cjs +``` + +**Why This Matters:** +- Prevents stale stream keys from shell environment +- Ensures PM2 picks up correct keys from .env file +- Required for CI/CD deployments + +### PM2 Configuration + +Production deployment uses PM2 for process management: + +```javascript +// From ecosystem.config.cjs +module.exports = { +
