Entitlement decision for a batch API client

How should entitlement be decided for a batch API client?

Batch API client decision guide for entitlement decision, connecting Maha's implemented machine controls to book concepts without treating the books as technical evidence.

Bounded answer

For batch API client, decide entitlement to a bounded batch request from the active principal, exact offer or resource, granted scope, expiry, revocation state, and remaining quota. Discovery, prior access, or possession of an identifier is never sufficient.

Input contract

What must be fixed first

Authenticated principal

Exact offer or resource identifier

Active grant and policy version

Expiry, revocation, and quota state

Procedure

Work the decision in order

  1. 1

    Resolve identity without trusting caller-supplied ownership.

  2. 2

    Load the exact grant and current policy.

  3. 3

    Match resource, operation, audience, and endpoint.

  4. 4

    Check time, revocation, and quota atomically.

  5. 5

    Return a bounded decision without exposing credential material.

Expected outputs

  • Entitled or refused state
  • Stable refusal code
  • Decision fingerprint and policy version

Refuse when

  • A nearby offer or predecessor revision is substituted.
  • Identity and grant belong to different principals.
  • Policy or grant cannot be read at decision time.
  • One authorized item cannot lend authority or quota to another item in the same batch.

Questions this guide answers

What is the minimum safe entitlement decision for a batch API client?

For batch API client, decide entitlement to a bounded batch request from the active principal, exact offer or resource, granted scope, expiry, revocation state, and remaining quota. Discovery, prior access, or possession of an identifier is never sufficient.

Which identity fields must remain bound for a batch API client?

Preserve tenant, credential, batch, item, and request digest; 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 a batch API client?

One authorized item cannot lend authority or quota to another item in the same batch.

Limits

  • One authorized item cannot lend authority or quota to another item in the same batch.
  • 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.
