Runtime boundary
The manifest defines the environment. Runtime authority controls the work.
Discovery produces an environment representation; it does not grant execution. Cuttlefish compiles named capabilities, classifies their effect, binds them to an agent runtime and organization boundary, applies policy and approval, then records resulting state, artifacts, receipts, and evidence.
Authority follows the runtime
Each operating agent receives capability scope for a specific runtime, target, origin, active policy, and set of limits. Missing, expired, mismatched, or revoked authority fails closed.
State survives the model turn
Task state, selected context, run history, pending approvals, artifacts, and evidence remain under Cuttlefish ownership instead of depending on a provider session.
Proof stays connected to action
Governed execution can update operational state, publish a durable artifact, and attach a signed receipt with attribution, action lineage, verification state, and evidence references.
