Zero-GC cinematic 2D camera. Deadzone, smoothed lookahead, deterministic shake via seeded RNG.

Engine, <idle-screen> custom element, plugin registry, seeded RNG, control-track, and types for idle-screens.

Zero-dependency seeded RNG for games — Mulberry32 PRNG with weighted drops, gaussian distribution, shuffle, and 2D vector helpers.

glissade core: signals, tracks, timeline document, evaluation, easing, springs, seeded RNG. Zero DOM/Node dependencies.

Shared foundation of LiveVariant: URL-encoded test configs with hash identity, stats secrets, seeded RNG, Thompson-sampling bandits (plain, bucketed, linear) with LLM warm-start priors, and event-sourced state derivation

Deterministic scenario simulator for frontend QA: stateful CRUD routes, seeded RNG, virtual clock, response sequences, faults and overrides, SSE and WebSocket routes with scheduled events and resume, per-run isolation, inspectable event log. Runtime-neutr

Write and backtest trading strategies against a multi-agent AMM token market with liquidity and vesting.

Write and backtest trading strategies against a multi-agent AMM token market with liquidity and vesting.

Shared layers behind small web games: a gated logger and a seeded RNG, imported by subpath.

Statistical distribution sampling (normal, exponential, Poisson, beta, gamma, etc.) with deterministic seeded RNG

Tiny, Very very bad seeded RNG for use in games.

Deterministic psychodynamic engine for LLM agents — seven-dimensional state vector, seeded RNG, byte-reproducible. The engine at the heart of ANIMA, as a library.

Deterministic psychodynamic profiles for LLM agents — 7-dimensional state, seeded RNG, byte-reproducible traces, exportable to system prompts.

Stapel 4-bit brick games: a tiny fixed-step engine (seeded RNG, input queue, grid model) with Tetris/Snake/Arkanoid/Racing/Tanks/Memory as pure modules, a <BrickConsole> LCD skin drawn in DS tokens with a phone keypad, local high scores, and a <WaitingGam

Core runtime for Runek: the World provider, useWorld, seeded rng, and the component contract.

Range data type parser and serializer for PostgreSQL

Game-agnostic, deterministic engine base (Engine contract, FrameDriver, seeded RNG, integer vec2, replay envelope). Games implement this contract in their own repos.

Seeded rng with custom seed

The Fisher-Yates (aka Knuth) shuffle for Node.js, with seeding support

The Demystify Play GameModule contract — deterministic seeded RNG, replay recording and the golden-replay harness. Zero runtime dependencies.
