Building graph-native systems from the bottom up: an operating system, fact-graph database, a typed language projected from it, and a coordination layer that humans and AI agents share. The thesis running through all of it — a program's source of truth should be a fact graph, not text files.

Fram — append-only fact-graph database (triples + Datalog). Every fact is an immutable, addressable triple; lifecycle is derived, never stored. Agents commit facts to one canonical log, so a whole class of merge conflict is impossible by construction — and renames re-point references by identity, not spelling.

Beagle — a typed Lisp where one source compiles to Clojure, JavaScript, Nix, and Odin, each rendered idiomatically. Built as an authoring surface for AI coding agents: a warm, def-level type checker returns pointed errors fast enough to collapse the repair loop. Beagle text is a projection of the Fram graph — delete the file, re-render it from the log, and it recompiles clean.

North — human + agent coordination/orchestration on Fram. Capture an intention as facts, then ask what's ready, blocked, and highest-leverage; the board is derived, never hand-maintained. The same coordinator drives multi-agent work: spawn, steer, dispatch.

• firn — typed authoring layer for NixOS / nix-darwin; catches config errors at the source line, before rebuild.
• gjoa — a Firefox fork where the power-user stack — blocking, tree-style tabs, vim navigation, workspaces — is native, not bolted on through extensions.
• wake — declarative web-app compiler; one checked entity graph projects to direct-DOM UI, SQL, a REST server, and tests — no virtual DOM, no runtime.

• Firefox - vertical-tabs bug fix
• Kanata - tap-hold-order mechanism
• Datastar Python SDK - Litestar bug fix
