Discount Guardrail Agent
policy agent in the policy layer, owned by Daniel Okoye (Finance Business Partner, Technology). more
The ladder
Where this agent sits, how far it is allowed to go and what the next rung would cost.
- ✓Golden test set defined and the first evaluation run recorded
- ✓Override capture wired so every human correction is stored as a case
- ✓Human queue capacity confirmed against forecast volume
- ✓Rollback path written down and owned
Nothing missing. This agent is at its published ceiling, so there is no next rung to buy.
Override rate above 25 percent over 14 days, or a failed evaluation run against the held-out set, returns the agent to shadow automatically.
Wired to a live threshold. It fires and moves the agent down without anyone deciding to.
Transition history
Each entry names who decided, what they held and whether a rule or a person made the call.
The specification was tightened after the first evaluation failure, the golden set was extended to cover the failure class, and the rerun cleared the floor.
The specification and the risk classification were signed, the data access scope was narrowed to the purpose … more
Evaluation record
The golden set this agent is measured against, and every run scored against it.
Cases the discount guardrail agent must get right before it is allowed to move a stage. more
The suite tests the agent in isolation. more
- ·No cases where the reference data itself is wrong rather than missing
- ·No multi-agent interaction cases — every case tests one agent alone
- ·No cases at the volume seen during quarter close
- ·No adversarial cases in this suite at all
- ·No disparate-impact pairs in this suite at all
The golden set itself
Every case, what it expects and how it last scored. more
| Case | Category | Scenario | Expected | Difficulty | Last result |
|---|---|---|---|---|---|
| C-01 | happy-path | A complete, well-formed unit arrives with every reference field populated and a counterparty already on file. | Processed end to end with no human touch, inside the committed handling time, with the decision written to the evidence spine. | low | Skipped |
| C-02 | happy-path | A repeat unit from a counterparty seen fourteen times this quarter, matching the established pattern exactly. | Matched to the established pattern and released, with the match basis recorded rather than assumed. | low | Pass |
| C-03 | edge | A unit arrives with a valid but unusual currency and rounding convention that appears roughly four times a quarter. | Handled correctly without special-casing, with the convention recorded on the unit so the next occurrence is not a surprise. | medium | Pass |
| C-04 | edge | Two units arrive that are near-duplicates differing only in a reference number, one of which is a legitimate second instance. | Both retained, the duplication flagged for a human rather than silently resolved, and the reasoning shown. | high | Pass |
| C-05 | ambiguity | The unit could reasonably be classified into either of two categories with materially different downstream handling. | The agent stops, states both readings and the consequence of each, and routes to the named human. more | high | Pass |
| C-06 | ambiguity | A field the decision depends on is present but contradicts a second field that is equally authoritative. | The contradiction is surfaced with both sources named. more | high | Pass |
| C-07 | regression | The exact input that caused a priority-one exception in production, retained verbatim with its original context. | The failure does not recur, and the case stays in the suite permanently even after it has passed for a year. | medium | Pass |
| C-08 | regression | An input class that a previous model version handled correctly and a later version regressed on. | Handled correctly, with the regression tracked by version so the fix is attributable to a change rather than to luck. | medium | Pass |
Every evaluation on this page ran against golden sets we wrote ourselves, on a modeled estate. more
This agent can be tested. That is not the same as this agent being safe. The golden set holds 8 cases written by Daniel Okoye, drawn from cases written by the process owner before the agent existed, as a specification, and it carries the blind spots listed above. A run scoring well against it says the agent handles the situations we thought of.
