From source checkout to running graph.

Before you start: use JDK 21, Maven 3.9+, Node.js 24 and npm. The current UI package requires Node 24 even though an older source quickstart still says Node 20.19+.

1. Build the release shape

   From the root of the current evaluation checkout, run the project’s release builder. It installs and tests the UI, builds it, verifies the 28-module Maven reactor and packages the executable JAR.

   ./ravenroot/scripts/build-release.sh

2. Launch on the loopback default

   The default bind stays on this machine. The server starts with a local-only disabled-auth warning; a non-loopback bind requires explicit authentication configuration.

   java -jar ravenroot/ravenroot-distribution/target/ravenroot.jar

3. Verify the runtime

   Open a second terminal and check health, engine status and the catalog actually installed in this deployment.

   curl --fail http://127.0.0.1:8080/health
   curl --fail http://127.0.0.1:8080/v1/status
   curl --fail http://127.0.0.1:8080/v1/node-types

4. Open the editor

   Visit http://127.0.0.1:8080, load executable GraphML and follow the catalog-backed palette. Start with Test before Run when a graph includes controlled external effects.

Proof run: current source commit fa922825f3a3801765c483aaaaa670327497c62d, JDK 21.0.11, Node 24.19.0, 28-module build. This page is a source-evaluation path, not a public installation promise.
