Access opens the layer end to end: the engine's verbs on your own corpus, the join against the pinned EPCIS 2.0 schema, and the MCP door for the agent that will run it after you. The address comes first; everything after it is optional.
Read before you sign up, if you prefer.
The layer's laws are on the landing page; the worked 856 run, the core-field argument and the reconcile transcript are on the blog; the family's event door — where the emitted events land — is epcis.dev, and its calculators answer on that origin with no key.
