# Appflowy Foundation

> Use when porting AppFlowy's offline-first sync kernels — assembling CRDT objects with disk persistence and cloud sync, routing typed events across an FFI boundary, running QoS background task queues, reconnecting realtime sockets, or implementing a local server that satisfies cloud traits without a backend.

# AppFlowy: local-first collaborative workspace foundation

## Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is
historical, revision-pinned evidence rather than timeless guidance. Current
project source, tests, requirements, and runtime behavior outrank this
projection and decide what ships.

## Provenance and revision

- Source record: `appflowy`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `main@5cf3a365dec0d59f64bad1ee4bb1050471a39b93`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Collab assembly; Document lifecycle; Event dispatch;
  Background tasks; Realtime & offline; Identity & plumbing.
- Scope and retrieval questions: `references/index.md#use-this-for`.
- Complete capsule chooser: `references/index.md#load-the-matching-source-dump`.
- Detailed grouped map: `references/index.md#capsule-map`.
- Source limitations and portability boundaries: `references/index.md#boundaries`.

## Retrieval

Open the index, choose one capsule matching the active question, and load only
that capsule. Revalidate its cited source and revision before relying on it. Do
not bulk-load the inventory, treat historical claims as current truth, or apply
this foundation as a procedure.
