Build with the composed StyleSeed method

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

The build method is the product. Score and screenshots are auxiliary evidence, not the source of design judgment.

Step 1 — Establish the rule set before code

If either .styleseed/project.json or .styleseed/artifacts/index.json exists, require a complete, valid registry and resolve the requested artifact with the installed resolver's scripts/resolve-context.mjs --project-root . --artifact <artifact-id> --agent <agent>. Read .styleseed/bundles/<artifact-id>.md and preserve .styleseed/manifests/<artifact-id>.json as provenance. Do not create STYLESEED.md, restart setup, or use a legacy bundle because a registry is incomplete, invalid, or lacks a compiled output. Resolve missing scope with the user. For changes spanning multiple artifacts, resolve and check each affected artifact separately.
