Engineering method
Make failure visible.Then engineerthe recovery.
Production AI fails across boundaries: model decisions, permissions, tool calls, state changes, downstream systems, retries, and business outcomes. Whitestone makes those paths observable, reproduces the failures that matter, hardens the control points, and verifies the resulting business state.

System instrumentation
We trace the systemaround the model.
We trace decisions, authority, tool calls, state changes, recovery, and the verified business state, end to end.

Failure states
One system. Seven stateswe engineer for.
Every production AI incident moves through the same states. We engineer, break, and verify each one before your customers meet it.
- 01IntactExpected path, expected state.
- 02GatedAuthority checked before any action.
- 03LayeredEvery tool call traced and bounded.
- 04MisalignedA retry repeats a refund.
- 05RecoveringCompensation reconciles the ledger.
- 06RestoredThe business invariant holds again.
- 07VerifiedEvidence proves the final state.
Production AI Diagnostic
Take one consequential workflow. Expose the gaps. Harden what matters.
A bounded engagement for teams whose AI already touches real systems. We map one consequential workflow, expose its control gaps, and leave a clear path to hardening and verification.
Map
Define the consequential workflow, actors, permissions, state changes, and business invariants.
- Workflow map
- Actor & permission model
- State transition map
- System trace definition
Harden
Expose failure modes and engineer the controls that make the workflow safe to operate.
- Failure matrix
- Authority boundaries
- Idempotency & recovery plan
- Observability instrumentation
Verify
Prove the resulting business state, document the controls, and hand off operating evidence.
- Verification report
- Runbook
- Evidence ledger
- Next-risk register
Real systems. Higher standards.
