Replay journals: a ring buffer of a title's intents with optional snapshots, and intent journeys with world postconditions

GPU rendering for Keel: packing helpers by default; paint-backend provides a shared GPU context, frame compositor, text, images, vector and brush rasterizers, UI effects and browser OffscreenCanvas; wgpu-backend adds full 3D scene and surface presenters

Sans-I/O OpenID Connect client protocol: PKCE S256, state and nonce, authorization URLs, the device authorization grant (RFC 8628), token, refresh and revocation requests and responses, ID-token claim checks and discovery documents, for public and confidential clients

Storage Ports with conditional whole-snapshot saves, shared memory, Unix atomic envelopes and browser Web Locks

Greentic - The digital workers operating system

Voxel worlds: chunk storage, greedy and LOD meshing through one MeshOptions, title-declared block models, block and sky lighting, streaming plans, DDA raycast, swept AABB collision, chunk colliders for the physics port, a character controller and cube-sphere planets

PhysicsPort backends on Rapier: RapierPhysics (3D) and RapierPhysics2d (2D), with large-world origin rebasing, buoyancy, soft-body attachments, debug wireframes of colliders, contacts and joints, and optional parallel and enhanced-determinism solvers

UI: Components, Signals, constraint/flex layout, motion, themes and art skins, SVG import, forms, Markdown, paint and vector canvases, accessibility semantics, pooled world-space popups and HUD widgets

PhysicsPort contract (bodies, shapes, joints, queries, character movement, large-world origin rebasing), rigid bodies as ECS components, skeleton ragdolls with powered pose tracking and animation blending, wheeled vehicle with skeleton wheel rigs, XPBD soft bodies, Position Based Fluids and MLS-MPM on CPU and wgpu compute, and Voronoi fracture

An SCTP implementation for WebRTC Data Channels

Hierarchical scenes and prefabs: versioned keel.scene documents validated against a component registry, spawned into and saved from a World, with glTF files as prefabs, Animator playback and authored controls on imported and code-built skeletons, and world cell content (.kcell) with its generator and bake

Characters: the versioned keel.character document, layered wearables with index-rebuilt region hiding, joint-scale creator sliders without shear, read-only editor projections and typed intents, and the Character fragment that drives an anim set, a joint palette and morph channels headlessly

Time services: pause and time scale, timers, host timers with jitter, per-frame timing (FrameTime), unscaled service timing (ServiceTime), and a discrete scheduled-tick queue

Paint display list: PaintOp, node effects, canvas point lights, the SoftwareCanvas CPU rasterizer, the text layout and pixel rules it shares with the GPU UI renderer, paint-list diffs, and standalone SVG document export

Navigation: navmesh bake, optimal any-angle and corridor queries, crowds, grid and graph pathfinding, multi-agent path finding, steering
