Constructive Platform

Consolidated reference for the Constructive platform's core architecture: blueprints, authorization, services, deployment, server configuration, cloud functions, environment configuration, and the CLI execution engine.

Blueprints

• Declarative schema provisioning system — define complete domain schemas as portable JSONB documents
• Two-layer model: blueprint_template (shareable marketplace recipe) and blueprint (owned, executable instance scoped to a database)
• Definition format: entity_types[] (Phase 0 entity provisioning), storage (Phase 0.5 app-level storage), tables[] with nodes[], fields[], policies[] (using $type discriminators), and relations[]
• construct_blueprint() executes a draft blueprint, provisioning real tables and relations via secure_table_provision + relation_provision
• copy_template_to_blueprint() copies a template to a new blueprint with visibility checks and copy_count tracking
• Merkle-style content-addressable hashing: definition_hash (Merkle root) and table_hashes (per-table UUIDv5 hashes) for deduplication, provenance tracking, and structural comparison
• Hashes are backend-computed via trigger using uuid_generate_v5(uuid_ns_url(), jsonb::text) — same pattern as object_store.object_hash_uuid()

Triggers: "create a blueprint", "blueprint template", "construct blueprint", "copy template", "blueprint definition", "definition hash", "table hashes", "schema marketplace", "blueprint provisioning"
