Created 11 packagerepo-specific workflow plugins: - auth_verify_jwt - JWT token verification - auth_check_scopes - Scope-based authorization - parse_path - URL path parameter extraction (Express-style) - normalize_entity - Field normalization (trim, lower, unique, sort) - validate_entity - JSON schema validation - kv_get/kv_put - RocksDB key-value operations - blob_put - Filesystem blob storage with SHA-256 hashing - index_upsert - Index entry management - respond_json/respond_error - Response formatting Created string.sha256 plugin: - Compute SHA256 hash of strings/bytes - Optional "sha256:" prefix - Used by packagerepo for content-addressed storage All plugins follow standard pattern: - Class extending NodeExecutor - Factory with create() function - package.json with metadata - Access external state via runtime parameter Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
