420 Launchpad concepts

• Project — a registered launch subject with a controller, sale asset, metadata commitment and issuance commitment.
• Sale — the bounded sale configuration associated with a project.
• Allocation — protocol-recorded entitlement or allocation state for a participant.
• Controller — the address authorized for project-scoped actions allowed by policy; it is not universal protocol authority.
• Metadata commitment — a hash commitment to project information; it does not make the information truthful.
• Issuance commitment — a commitment to the intended asset/issuance configuration; users must still verify the resulting asset and transaction.
