Versions, checkpoints, and remixes

Keep source history distinct from immutable release versions.

Fixtures are {name,input,expected} with expected equal to the full output object. Include 1–50 tests. testPackage() returns a SHA-256 content digest, pass/fail and structured results. Changing source, manifest or fixtures invalidates that report. CLI pack requires passing tests. Releases are immutable and require tests against the exact digest. Restoring a checkpoint creates a new history entry.

Use Remix as new build for an independent identity and initial 0.1.0 version. provenance.remixedFrom records the source identity, version, and SHA-256 digest. Next patch version increments the release version; checkpoints remain independent of release numbers. The digest identifies content, not a verified publisher signature.

Download source + history + SDK exports a ZIP with my-block/stillmade.block.json, my-block/src/recipe.json, my-block/tests/fixtures.json, history.json, a working package snapshot, the SDK implementation, CLI, documentation, and instructions for your own LLM. Run node packages/block-cli/cli.js pack my-block rebuilt.stillmade.json from the extracted folder (Node.js 22+; no dependency installation required). Open the original build in StillMade and import the rebuilt file to append an external-revision checkpoint. A different package identity opens as a new draft.

Built-in catalog blocks have Download source + SDK too. These archives contain their client implementation and local source dependencies. They are host source snapshots for external editing/review, not independently installable recipe packages. Server implementation, credentials, and project data are not included.
