Reauthorize elevation immediately before a support repair commits

Practice briefBugAdvanced

An agent starts a repair, loses access, then the pending request commits using the authorization decision from several minutes earlier.

Your next step

Review it, then add it to your workspace.

The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.

Project context

A fictional support console can reveal protected account settings and run repairs. The team needs bounded elevation, clear reasons and durable records of what happened.

Setup prerequisites

  • Create synthetic support actors and organizations.
  • Implement a local authorization boundary and append-only audit store.

Preceding work

Complete these dependencies, or supply their agreed outputs before taking this ticket.

Acceptance criteria

  • Reload actor and grant authority in the mutation transaction.
  • Check target scope, permitted operation and expiry.
  • Revoked or expired grants leave domain state unchanged.

Implementation constraints

  • Use controlled barriers to model revocation between read and commit.

Verification to include

  • Commit a repair under an active matching grant.
  • Revoke at the barrier and verify rollback with no repair effect.

Deliverables

  • Commit-boundary authorization guard

Rollout and recovery

Canary the guard on synthetic repairs; disable repair writes if authorization freshness fails.

Value of the work

For the engineer: Practice privileged workflows, denial paths and audit integrity.

For the team: Review accountable support operations without unnecessary access to customer data.

Evidence boundaries

Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.

Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
