Architecture

apps/ are runnable surfaces; packages/ are the shared layers they compose from. This is the code map — read it before exploring code.

apps       cli   www   www-docs   workflow-conductor
             │ consume
packages   @arbe/core
             │ composes
           streams  sandbox  task  errors

cli runs on bun; www is sveltekit on CF Workers; www-docs is astro/starlight; workflow-conductor is the durable-workflow daemon on the arbe1 sprite — deliberately thin (absurd-sdk + pg only, no @arbe/core; see workflows).

Packages

@arbe/core — the domain hub. Per-entity write modules (houses, agents, environments, threads, entries, configs, workflows), the canonical schemas every other layer maps its data into, membership and permission helpers, and the pi session adapter.
@arbe/streams — the durable-stream layer thread entries flow through (client, gateway, server).
@arbe/sandbox — the sandbox runtimes that run agent work, daytona by default.
@arbe/task — the repo-native task graph in .arbe/tasks/.
@arbe/errors — shared error types.
