AND Claim

Claim records one owner for one whole executable delivery unit without changing scope. Invocation authorizes an ordinary safe claim after current evidence is validated.

Workflow Contract

Use and-workflow-contract with work-records.md and delivery-units.md for Read Delivery Unit, Record Ownership, and Reference Implementation Artifact before claiming.

Use Read Delivery Unit for the current source of truth, then Record Ownership for one logical claim and Reference Implementation Artifact when existing evidence must be linked. Record Ownership and the durable Claim receipt are one logical mutation; do not emit duplicate ownership evidence. The workflow contract owns how current ownership, receipts, and implementation artifacts are represented and derived. If repository setup or the contract is unavailable, stop and route to setup-and or ask the user to install the missing skill.

Atomic Claim Unit

A claim unit is either:

• one single issue package; or
• one parent PRD package plus all child slices.

If the user points at a PRD child, resolve and validate the parent delivery unit. Record ownership on the public delivery unit; for a PRD, one parent ownership record covers every child. Internal delegation may allocate child work, but it does not create child ownership or reduce the parent owner's responsibility.
