Bounded answer
For entitlement service, bind an entitlement decision to an authenticated identity, exact allowlist, request digest, quota, deadline, and endpoint before execution. Refuse the call if any binding is missing, stale, substituted, or broader than the grant.
Input contract
What must be fixed first
Authenticated principal and credential fingerprint
Exact tool and endpoint selector
Active grant with scope and expiry
Request digest, quota ceiling, and deadline
Procedure
Work the decision in order
- 1
Resolve the credential to one active principal.
- 2
Match the requested tool and endpoint to the grant.
- 3
Reserve quota against the replay-safe request identifier.
- 4
Execute only the frozen selector inside its time and resource bounds.
- 5
Record outcome, consumed quota, and an immutable receipt.
Expected outputs
- Allow or refuse decision with reason code
- Bounded execution result or no result
- Digest-bound execution receipt
Refuse when
- Selector or endpoint differs from the authorized value.
- Grant is absent, expired, revoked, or already exhausted.
- The same request identifier arrives with different content.
- Eligibility must be recomputed from the active grant rather than copied from a prior response.
Questions this guide answers
What is the minimum safe bounded execution for an entitlement service?
For entitlement service, bind an entitlement decision to an authenticated identity, exact allowlist, request digest, quota, deadline, and endpoint before execution. Refuse the call if any binding is missing, stale, substituted, or broader than the grant.
Which identity fields must remain bound for an entitlement service?
Preserve principal, offer, grant, scope, and expiry; refuse the operation when any edge is missing or belongs to another lifecycle.
What should happen on an exact replay?
Return the original bounded decision or result without consuming quota, delivering, or acknowledging a second time.
What role does the linked book play?
It contributes a conceptual framing for boundaries, resilience, or governance. It is not evidence that the technical control exists or works.
What does this guide not establish about an entitlement service?
Eligibility must be recomputed from the active grant rather than copied from a prior response.
Limits
- Eligibility must be recomputed from the active grant rather than copied from a prior response.
- The linked book supplies a conceptual lens only; the operational contract and implementation remain the authority for machine behavior.
- This guide does not authorize production mutation, payment, deployment, or access to a private evidence corpus.
