🪶 How it composes

The stack.

Each layer is built on the layer below. spec-sync is the foundation. fledge and Merlin both sit on it. Showcases at the top (corvid-chat, Podo, Rita) pull from every layer at once.

Read it top to bottom

  1. 1. Showcases at the top are what people actually use: corvid-chat (federated E2EE chat, the full-stack demo), Podo (multi-platform weather app, the consumer surface), and Rita (the weather API backend). All three in development. None 1.0 yet.
  2. 2. Agent tools in the next layer are how AI participates: Merlin is the agent runner in active development (consumes fledge plugins, plus a lot more) and corvid-agent is the released platform sessions run on.
  3. 3. Primitives are the two general-purpose libraries: AlgoChat (encryption, six implementations) and fledge (the dev-lifecycle CLI. Crazy because plugins). Released, used in CI everywhere.
  4. 4. spec-sync is the foundation. Both fledge and Merlin are built on it. Markdown specs are the contract; drift between code and spec fails the build. The thing the whole stack depends on staying honest.
  5. 5. Algorand is the substrate. AlgoChat settles on it for on-chain transport; corvid-agent settles on it for memory + identity. Dashed lines on the diagram mark the chain edges.

Each layer depends on the layer below. That's the workshop-that-compounds bet in one diagram: every new primitive sharpens every layer above it.
