-sprout-cli        ← Agent-first CLI for interacting with the relay
-sprout-admin      ← Operator CLI
-sprout-test-client← Integration test harness

-**Key design principle:** The relay is the single source of truth. All state
-flows through the event store. Crates communicate through the database and
-Redis pub/sub — not through direct function calls across crate boundaries
-(with the exception of `sprout-core` types, which are shared everywhere).

+**Event kinds are the only switch.** Every action in the system — a message,
 a reaction, a workflow step, a canvas update — is a Nostr event with a kind
 integer. Adding a new feature means defining a new kind. No breaking changes
 to existing clients.

+## Ecosystem
+
+Sprout is developed across multiple repositories. This repo (`block/sprout`)
+is the open-source home for all application code — the relay, desktop app,
+mobile app, CLI, and agent harness. Internal repositories handle
+enterprise-signed builds and infrastructure deployment.
+
+See [AGENTS.md § Ecosystem](AGENTS.md#ecosystem) for the full repo table and
+dependency diagram.
+
+**External contributors:** Fork `block/sprout`, open a PR, and CI runs
+automatically. No special access is required.
+
+**Block team members:** See the internal
+[sprout-releases CONTRIBUTING.md](https://github.com/squareup/sprout-releases/blob/main/CONTRIBUTING.md)
+for team access setup, onboarding, and the full repo inventory. See
+[RELEASING.md](RELEASING.md) for the release process.

 ## Internal Releases
 
-After the OSS release ships, trigger an internal build via the **sprout-releases** Buildkite pipeline:
-
-1. Go to the [sprout-releases pipeline](https://buildkite.com/runway/sprout-releases) and click **New Build**
-2. Fill in the input fields:
-
-   | Field | Value | Notes |
-   |-------|-------|-------|
-   | `version` | `0.3.0` | Semver, no `v` prefix |
-   | `sprout_ref` | `v0.3.0` | The OSS git tag — use the tag, not a branch name |
-   | `relay_url` | *(default)* | Pre-filled with the production relay; usually leave as-is |
-   | `publish_latest` | `true` | Updates `latest.json` on Artifactory so installed apps auto-update. Set to `false` for test builds. |

-Internal desktop builds display a `-block` suffix in the version (e.g., `v0.3.0-block` in the Settings panel). This distinguishes them from OSS builds at a glance. iOS builds and GitHub release tags use the clean version (`0.3.0`) since Apple's `CFBundleShortVersionString` rejects pre-release suffixes.

 ## What Gets Published
 
 Each release produces two GitHub releases:
 
-1. **`v<version>`** — the user-facing release with the `.dmg` installer (macOS) and `.deb`/`.AppImage` (Linux).
