What this agent does

Re-checks the supplier, never clears it

In

  1. 01

    A supplier is designated, and blocking attaches that hour, with no grace period anywhere in it.

  2. 02

    A payment blocks in flight, and 31 CFR 501.603 gives ten business days, then an annual report.

Reason

  1. 03

    An ownership changes, and 31 CFR 587.406 blocks the entity with no listing anywhere.

  2. 04

    A running contract meets it, and performance is prohibited, leaving a wind-down licence.

  3. 05

    A wind-down licence expires at a stated hour, so the answer is a clock, not a decision.

Decide

  1. 06

    A re-screening interval is sought, and OFAC FAQ 28 leaves it to your own written policy.

  2. 07

    A supplier is debarred, and FAR 9.405 binds agencies, reaching you via FAR 52.209-6.

Out

  1. 08

    A supplier files, and 11 U.S.C. 365(e)(1) voids the insolvency clause you drafted.

  2. 09

    Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

Sweeping, recording and raising belong to the agent. Blocking, stopping a payment, terminating and filing belong to a named risk owner, who does all four.

Example workflow

One supplier, sweep to escalation

  1. 1Supplier base receivedSupplier master records, ownership data, watchlist feeds, exclusion records and court dockets
  2. 2Sweep run and recordedThe lists checked, the ownership read, the hour the sweep ran and what it could not reach
  3. 3Change raisedThe event, the supplier it attaches to, the sources under it and confidence
  4. 4Controls appliedMatch checks, ownership checks, source-currency checks and detection confidence

No human action required

Stages 1 to 4 run unaided, and nothing is blocked or filed at any of them — the agent is sweeping, and the risk owner lane opens at the escalation gate.

5DecisionSplits at the escalation gate
Event matched and sourced

Goes to the named risk owner.

Anything unresolved

Adds a compliance counsel read first.

Risk owner review

The event is held with its sources, the hour it was seen and what the sweep could not check.

Escalate · Add source · Send to counsel review

Decided — by the named risk owner

  1. 6Supplier and payment records updatedOnly where write access and records policy allow it
  2. 7Outcome evaluatedDetection lag, source coverage, owner corrections and what review found

Corrections

Each risk owner correction is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required

8 items

  • Deciding that a supplier is blocked.
    • Stopping or releasing a payment in flight.
    • Terminating a contract with a supplier.
    • Filing a report with a regulator.

  • Automation boundary

    Agent acts unaided

    • ✓Sweep the onboarded supplier base on the stated cadence.
    • ✓Record what each sweep saw and the hour it ran.
    • ✓Raise what changed since the last sweep to the named risk owner.
    • ✓Show which suppliers the sweep could not reach, and what blocked it.

    Nothing is blocked or filed except by a named risk owner, inside the agreed boundaries.

    • Judging whether an ownership crosses the rule.
    • Telling a regulator what was found and when.
    • Setting the cadence a supplier base is swept at.
  • Changes to the cadence, escalation or watchlist rules.

Example output

One risk event, annotated

This serves a procurement team who may have to show when a designation was seen and who was told; below is one event exactly as the agent leaves it.

As received

Read from the watchlist feed and the ownership record on file, and it claims nothing beyond them.

What the record holds

  • Watchlist feed
  • Ownership record
  • Court docket index

Why no escalation here

Deciding a supplier is blocked is a judgement the risk owner makes.

What the score decides

Below the configured threshold the event gets a counsel read before the owner sees it.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value lands

Value 01 – 04

Every sweep

Against the supplier base on file

03Evidence

What the sweep read

Forced-labour import evidence answers for goods stopped at the border; this is the supplier who was clean at onboarding and is not clean now.

01Approved path

Clean at onboarding, not now

The fifty percent rule needs no regulator: ownership moves, and the entity is blocked with nothing published anywhere.

02Human review

What was checked, and not found

Checked across the instruments surveyed: no rule makes an ordinary buyer re-screen a supplier it already onboarded, the ongoing-monitoring duties bind banks and funds, and the filings run only after a find.

04

Build an evidence trail

The designation, the hour it landed and the person who was told stay together.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

  • Sanctions and watchlist data

    • OFAC SDN
    • consolidated lists
    • EU, UK and UN designation feeds

  • Ownership and corporate data

    • Company registries
    • filings
    • Beneficial-ownership records

  • Exclusion and court records

    • SAM exclusion records
    • agency lists
    • Bankruptcy dockets and filings

Agent

Supplier-risk monitoring

  • Sweeps the base
  • Records the change
  • Raises to the owner

  • Purchasing and payment systems

    • SAP Ariba
    • Coupa
    • Oracle ERP
    • Payment runs and open purchase orders

  • Observability & evaluation

    • OpenTelemetry
    • Langfuse
    • Supported monitoring/evaluation sources

Integration availability depends on the client's existing systems and API access.

How Nestack evaluates it

Evaluate the whole sweep — not only the change that comes out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the change the risk owner reads

  1. E1Final-output evaluationDid the change carry its sources and the hour it was seen?
  2. E2Step-level evaluationDid the agent read the right feeds, the right supplier and the live scope?
  3. E3Tool evaluationDid it read and write the correct supplier and the correct event?
  4. E4Confidence calibrationDo low-confidence matches actually attract more owner corrections?
  5. E5Slice evaluationHow does performance change across individual risk events?
  6. E6Business outcomeHow many changes needed a correction before the owner acted?

Floor — the sources a sweep rests on

Failure modes

Where each failure originates in the agent

Seven failure modes, each set at the stage where it first shows.

Affected slices

Private ownership chains absorb the corrections

An event-level detection figure can read clean while privately held ownership chains carry most of the corrections. Nestack reports the correction rate by risk event, not only in total.

Evidence-linked improvement

What a week of not looking costs

A loop ends when the designation nobody saw for a week is a standing case. That suite is what the next sweep run is measured against.

Improvement cycle · five stages

Switchback — the path turns at Improve and returns at Learn

  1. 01

    Detect

    Correction rate rises on privately held ownership chains.

  2. 02

    Diagnose

    The designation published on a Friday afternoon, against a supplier already on the payment run that goes out Monday, is worked back until one cause is left.

  3. 03

    Improve

    The change leaves numbered, and the sweeps that caused it ride with it.

  4. 04

    Verify

    Nothing ships while one sweep case is still failing.

  5. 05

    Learn

    One case joins the suite, one line joins the escalation rules.

  6. Learn → Detect

    The return edge. The next sweep is measured against a suite one case longer.

Next step · Procurement AI agent

Build a supplier risk monitoring agent around the sweep your base has not had since onboarding.

Show us your supplier base and the day each name was last re-checked. The duty attached the hour that supplier was designated, not the day you found out. Nothing is filed for having looked: blocked property is reported annually, a rejected transaction within ten business days.
