Publish execution_plane 0.2.0 first. The historical execution_plane 0.1.0 package is a monolith containing these same JSON-RPC modules and will fail a warnings-as-errors consumer compile with module redefinitions.

Before publishing the package:

  1. Verify Hex resolves execution_plane 0.2.0, never 0.1.0.
  2. From a clean standalone checkout/package extraction with no sibling core path, run mix deps.get and mix compile --warnings-as-errors.
  3. Run mix ci.
  4. Run mix hex.build.
  5. Inspect the package manifest and confirm the execution_plane requirement is ~> 0.2.0.
  6. In the authorized release phase, run mix hex.publish --yes.
  7. Create the lightweight tag execution_plane_jsonrpc-v0.1.0, push it, and verify the remote tag

This monorepo already uses the plain v0.1.0 tag for the generated execution_plane distribution. Component-qualified tags are therefore required so a component release identifies its actual source commit without moving or colliding with that published tag.

The package manifest should include README.md, CHANGELOG.md, LICENSE, assets/, guides/, lib/, .formatter.exs, and mix.exs.
