The AbsoluteJS package manifest contract: typed manifests (settings schema, env requirements, adapter slots, wiring, AI tools) every @absolutejs/* package ships from its ./manifest subpath, plus bridges to AI tool maps and MCP registries.
Pure cost-model substrate for the AbsoluteJS PaaS. createPlan + computeInvoice turn @absolutejs/metering usage snapshots into integer-micros invoices — no float drift, no SDK peers.
