Post or read a board-room Matrix event: a gate, question, follow-up, waiting card, notice or answer	treaty-matrix-events

npm install @superjackfruitlabs/treaty-cloudevents@0.0.13

Every package is an ES module with its TypeScript types. The data packages (event-schemas, matrix-events, ecosystem-identity) export their JSON files by subpath, so a reader in another language can take the same files from the package or from the repository.

Packages are published from GitHub Actions with npm provenance when a vX.Y.Z tag is pushed. Each release’s notes are on the GitHub releases page.
