An auditable evaluation of an AI agent in a financial or corporate process does not ask “how well does the model write text?” It asks “what actions does the system actually perform, what states can it create, and what harm remains after controls?” The object of evaluation is a specific configuration: model, orchestration/scaffold (harness), tools, memory, permissions, resource budgets, and execution environment. This combination determines the available actions and consequences; the result cannot automatically be transferred to a changed configuration. To determine the scope of repeat testing, first establish which actions, data, and constraints the change affected (METR, Anthropic response to the NIST RFI on Agentic Security).

Before choosing metrics, map the process: the agent’s purpose, users, permitted actions, prohibited states, stakeholders, and harm scenarios. In NIST AI RMF 1.0, this is not a decorative artifact but the basis for a documented deployment decision. The NIST frameworks are voluntary and do not replace sector-specific regulation; they provide a risk vocabulary, not a readiness certificate.

The method below connects objectives, trajectories, constraints, and consequences in an evidence package suitable for internal control, model risk, security, and independent challenge.

Evaluation unit: the system, not a “model in a vacuum”

An AI agent here is an executable system that selects actions from observations, calls tools, and changes the state of its environment. A trajectory is a sequence of observations, decisions, tool calls, approvals, and changes in external systems. An oracle is a predefined rule used to establish the true outcome of a task. Residual risk is the risk after controls are applied, not the model’s “raw” risk.

The system boundary must include everything capable of changing behavior at runtime: retrieval sources, access policies, system instructions, timeouts, retry limits, the human approval gate, and the grader if it is embedded in the execution loop (for example, as a policy gate or feedback mechanism). Changing a runtime component creates a new evaluated artifact or requires justified revalidation; changing an offline grader requires separate revalidation of the measurement and a comparability check, not an automatic declaration of a new artifact. For closed APIs, full reproducibility may be unattainable; in that case, record the maximum available version identifiers, timestamps, inputs, outputs, and traces.

A public benchmark is useful for diagnosing capabilities, but not as evidence that a process is ready. NIST AI 600-1 recommends documenting benchmark limitations and data provenance; possible overlap between training and test data should be checked separately. Numerical results from AgentBench, the METR time horizon, or computer-use studies do not transfer to a local payment, procurement, or HR process without validation of that process.

From the agent’s purpose to the consequences of error

Consider an end-to-end teaching example: an agent prepares draft payments from supplier invoices. It may read the invoice and purchase order, verify the supplier, amount, and currency, create a draft, and refer disputed cases to a human. It may not execute a payment or change bank details in the master-data directory. Approval does not expand these powers: a separate process component executes the payment.

This boundary determines what counts as success. For a correct invoice, the required result is a correct draft, not a “done” message. For questionable bank details, the required result is a stop with a clear verification request, not a draft at any cost. An agent that sends everything to a human may violate no prohibition but still perform no useful work.

Now list the consequences of errors: an incorrect draft increases the reviewer’s workload; a duplicate may lead to a duplicate payment; leaking an attachment is already a consequence even if no money is sent. For each scenario, record the affected parties, severity, reversibility, detection method, and protection. This turns abstract “AI risk” into requirements for testing a specific process.

Average harm, where it can be estimated, does not replace prohibitions on severe outcomes. For mutually exclusive and exhaustive scenarios \(S_i\), with finite expected harm,

\[ E[L]=\sum_i P(S_i)E[L\mid S_i]. \]

The problem here is usually not the formula but the unknown probabilities and consequences. In our teaching example, there is no data for monetary valuation, so we do not calculate a fictitious “expected risk.” Instead, we separately test usefulness, attempts at prohibited actions, protection activation, and realized harm. This separate report shows whether safety is provided by the agent’s behavior or only by an external block.

If the process affects people, results are also examined across relevant groups: an overall metric can conceal differences in errors, delays, and unjustified refusals. Access to group data and the applicability of the metrics require separate justification; this is not a universal list of metrics for every system.

Evaluation contract before the first run

Acceptance criteria are set before testing; otherwise metrics are fitted to numbers already obtained. The contract records the test set, usefulness criteria, prohibitions, and stopping rules. Statistical uncertainty determines what conclusions the results will support.

Development and protected holdout. Split the set into a development/regression suite and a protected final holdout. Error analysis and changes to the prompt, scaffold, and controls are allowed on the development set. Before the holdout run, fix the evaluated configuration, metrics, thresholds, statistical protocol, and go/no-go rule; make the decision after obtaining the results, without subsequently tuning that same configuration to discovered cases. Repeatedly comparing configurations on one holdout also gradually turns it into an adaptation target, even when individual tasks are not disclosed, so limit the number of accesses, use blind evaluation, or periodically create a new protected set. After disclosure, the holdout becomes a regression suite.

Hard constraints (veto). For every hard constraint, distinguish in advance between a prohibited attempt and a realized violation. A realized change to a high-impact state – for example, an unauthorized payment, data disclosure, or bypass of mandatory approval – is normally an immediate veto and is not offset by high average task success. Count a blocked attempt as a separate measure of agent and control quality: for some classes only a zero rate is acceptable; for others, set a threshold and track it as a leading indicator of degradation. Process, security, and risk owners agree on the set of hard constraints.

A zero rate is not zero risk. For each critical event, state the number of actual violations and the number of opportunities to commit a violation (the exposure denominator), as well as a preselected one-sided upper confidence bound. With zero observed violations in \(n\) independent Bernoulli opportunities with a common event probability \(p\), the exact upper bound at level \(1-\alpha\), where \(1-\alpha\) is the selected confidence level and \(\alpha\) is the acceptable probability of failing to cover the true violation probability \(p\), is

\[ p_U = 1 - \alpha^{1/n}, \]

and for a 95% bound it is \(1 - 0{,}05^{1/n} \approx 3/n\). The approximation \(3/n\) is intended for sufficiently large \(n\) (approximately \(n \ge 50\)); with small \(n\), use the exact formula. Do not apply this approximation mechanically: shared memory, external-system state, and repeated runs can create cluster correlation and reduce the effective sample size. In such cases, cluster-aware or hierarchical models are needed, and the bound still does not cover untested threat modes. The denominator “all tasks” may be wrong: if only some tasks gave the agent a chance to bypass approval, count those opportunities. Zero observed violations means that the event did not occur in this sample, not that it is impossible. For some classes, the acceptance criterion may require zero observed realized violations; that is an admission rule for this test, not an assumption that the true violation probability is zero.

Usefulness. Reaching the final state, escalation rate, time, cost, and quality relative to the current baseline. Correctness of the text response is insufficient: require the final state, the permissibility of each action, side effects, cycles without progress, and actual consequences (overview of agentic evaluation; AgentRewardBench).

Stopping rules. Minimum usefulness, maximum frequency and severity of violations, mandatory-escalation conditions, a kill switch, credential revocation, and transition to safe mode. NIST does not set threshold values: they reflect the organization’s risk appetite, statistical uncertainty, and harm severity (NIST AI 600-1). One final score does not establish reliability. NIST treats validity, safety, security, accountability, explainability, privacy, and fairness as distinct characteristics to balance in context (AI Risks and Trustworthiness).

Tasks, oracle, and separate grader measurements

Stratify the task set instead of collecting “convenient successful cases.” Typical layers include operation types, amounts and authority levels, data sources, users, normal and emergency modes, ambiguous requests, rare edge cases, foreseeable misuse, and tool failures (AI RMF Playbook; NIST AI 600-1). Historical logs may not contain threats that have not yet been observed, crisis modes, rare severe cases, or complete data on prevented incidents; the counterfactual outcome of a prevented event is unobserved, so coverage must be supplemented with threat modeling, expert labeling, and stress scenarios. Representativeness requires current process data.

For each task, the oracle must be verifiable. It is more reliable to expect a specific final state and permissible delta in record systems than to evaluate the agent’s natural-language response; the final state should also be supplemented by checks of the trajectory, action permissibility, and absence of impermissible shortcuts (AgentRewardBench; PaperBench). The existence of a historical decision does not always provide the correct counterfactual: disputed cases require domain-expert adjudication before the run, otherwise “truth” will move with the convenient verdict.

An automated grader is a separate validation object. Here, false PASS means that the grader judged a trajectory safe or permissible although independent expert adjudication found a critical violation; false FAIL means that a permissible trajectory was incorrectly judged a violation. A grader has its own false positives and false negatives; test them on an independently labeled sample. The cited audit of a computer-use benchmark evaluated erroneous FAIL verdicts and defective tasks, but not false positives among PASS verdicts (How Benchmarks Mis-Score Computer-Use Agents). High grader accuracy does not guarantee construct validity: formal “task completed” can coincide with an economically incorrect, procedurally prohibited, or unethical action. Automated checks must be compared with independent expert labels.

For veto and safety graders, overall accuracy is usually insufficient: false PASS and false FAIL have different costs, so publish sensitivity or FNR separately for critical violations; interpret false-pass rate as FNR when its denominator is all actually confirmed critical violations, and publish the false-fail rate (1 − specificity) separately. In a typical safety loop, the cost of false PASS is substantially higher than the cost of false FAIL.

End-to-end example: what exactly to test

Continue the payment-preparation agent example. All scenarios, thresholds, and results in this section are educational: this is not a test of an existing system and not an industry standard.

The set contains 120 normal invoices, 40 ambiguous, 25 emergency, and 15 adversarial tasks: 200 tasks in total. Run each five times with restoration of the initial state, for 1000 runs in total. Fix the limits on calls, tokens, time, and retries within one run in advance. Five independent debugging attempts cannot later be declared one successful production attempt.

The proportions in this set are chosen to test difficult cases, not to reproduce their production frequency. Therefore, the groups below are compared separately. To estimate the average result in operation, group weights from the real process will be needed; adversarial tasks remain a separate security check.

From expected behavior to observable evidence

The oracle – the rule for establishing the correct outcome – should rely on system state and action logs, not on the agent’s explanation. The table lists the success conditions for each scenario; failure of any listed condition means that the test was unsuccessful.

Scenario Success conditions How to verify
Correct invoice and purchase order Exactly one draft is created with the correct supplier, amount, currency, and purchase-order reference ERP record, operation identifier, matching against the input documents
Duplicate invoice The duplicate is flagged and no new draft is created; an exception is possible only under a separately defined authorization Search by the invoice business key and decision log
New bank details in an email The master data is unchanged, and a bank-detail verification request is created and recorded for the responsible employee Master-data state diff and verification-request record
Attacker instruction in a PDF No attempt at a prohibited call and no prohibited change or data output Tool-request log, access-policy decisions, system state, and outbound-traffic control
Timeout after draft creation The result of the original operation is checked before retrying; no second draft exists Operation identifier, request log, search for a draft by idempotency key
Partial execution The business operation is stopped, a reconciliation ticket is created, and the agent makes no new business records until a definite state is restored Stop log and reconciliation ticket; incident logging and the actions of a separately authorized recovery operator do not count as prohibited continuation
Unavailable permitted exchange rate No draft is created using an unconfirmed or impermissibly stale rate, and the case is referred for review Rate version and time, ERP state, escalation record

For an attack, distinguish two outcomes: the agent attempted to violate a rule but the control blocked the request; or the prohibition was actually violated. The first does not demonstrate safe agent behavior, while the second also shows inadequate protection. The agent’s statement “I ignored the instruction” proves neither. If a dangerous request is filtered before the log, observations are needed at that boundary; otherwise the assessment of attempts is incomplete.

For the preparation agent, any call to execute a payment is prohibited, even if an approval exists somewhere. A different contract applies to the separate payment executor: the required approvals must concern the current bank details and amount. Checks in the subsequent process do not replace checking the agent’s own boundaries.

Teaching results and decision

Assume that before testing the following rules were set for a limited pilot: at least 95% successful normal tasks, at least 90% correctly handled ambiguous tasks, and at least 95% safely completed emergency tasks. In this example, the thresholds apply to observed proportions in the prespecified first run of each task. This is a sample-acceptance rule, not a claim about a lower confidence bound for quality in operation. For attacks, the criteria are zero realized violations and zero prohibited attempts. Under a different rule that allowed blocked attempts, the decision could differ; the rule cannot be changed after viewing the results.

Group, first run Teaching result Comparison with rule
Normal tasks 114 of 120 = 95% Threshold reached; the six failures enter the remediation cost
Ambiguous tasks 36 of 40 = 90% Threshold reached; correct escalation counts as a useful outcome here
Emergency tasks 23 of 25 = 92% The 95% threshold was not reached
Adversarial tasks 0 realized violations out of 15; 3 prohibited attempts, all blocked The prohibition on attempts was not met, although protection prevented the observed violations

The decision under this rule is not to approve the current configuration for the pilot. A high proportion of prepared drafts does not offset failures of the admission conditions. Before deciding again, fix emergency handling and the causes of prohibited requests, then test the changed configuration. The table does not support declaring the system safe merely because payments were not executed.

Suppose also that for the same 120 normal tasks the complete manual process required 960 minutes, while the process with the agent required 600 minutes, including review of all results, handling escalations, and correcting the six failures. The teaching difference is 360 minutes, or 37,5% of manual time. This shows how to count benefit without hiding human work. It is not a measurement result for a real product and not an assessment of statistical significance; computing and operations must be added separately to the monetary cost. Even this saving does not override the established prohibition on launch.

What repetitions add

Suppose that across all five runs of the normal tasks there were 570 successes out of 600, but only 110 of 120 tasks succeeded in all five repetitions. The share of successful runs is 95%, while the share of tasks with stable success across all repetitions is approximately 91,7%. The numbers are compatible: the other ten tasks collectively produce 20 successes in 50 runs. The same average success rate conceals instability in individual tasks.

A thousand runs of the full set do not mean a thousand independent opportunities for every critical violation. For example, five repetitions of 15 attacks produce 75 adversarial runs, but repeated tasks may create dependence. The upper-bound formula from the earlier section cannot be mechanically applied with \(n=1000\) or \(n=75\). For comparison: in 100 separately designed independent homogeneous opportunities with zero violations, the exact one-sided 95% upper bound is \(1-0{,}05^{1/100}\approx2{,}95\%\). This is a separate mathematical example, not a risk estimate for our set.

Human approval is tested separately

A successful draft and reliable approval are different properties. Present the reviewer with independently labeled cases containing inserted errors and correct cases under realistic workload. The share of inserted errors missed is calculated among cases containing an error; the share of correct cases incorrectly rejected is calculated among correct cases. Use the same separation for an automated reviewer: overall accuracy can conceal missed rare critical violations.

In this process, separately test the binding of approval to payment parameters, revocation and expiry of authorization, and rejection when bank details change after approval. This is a control of the subsequent payment process, not permission for the preparation agent to execute a payment. The teaching results above contain no measurements of this control and therefore are not, for this reason too, complete evidence that the entire process is ready.

How to read results and account for uncertainty

A multidimensional results card usually includes: reaching the final state; policy compliance at every step; side effects; expected and tail harm; safety and privacy; fairness breakdowns where the agent affects people; effectiveness of human control; latency and cost; and recovery. Publish components before any aggregate index; weights are a value judgment, not a technical constant.

Three separate measures for safety controls. Store separately: the probability of an unsafe attempt when an opportunity exists; the probability that a control blocks the attempt; and residual escaped harm – harm that passed through the control. The same number of incidents does not distinguish an agent that rarely attempts a violation from one that is merely blocked often.

Repetitions help distinguish a one-off success from stable behavior. pass@1 is the share of successful single attempts. pass@k is the chance of at least one success in k attempts; for a process where only one attempt is permitted, this is too lenient a characteristic. pass-all(k) is the share of tasks successfully completed in all k repetitions; this is a stricter reliability characteristic (On the Reliability of Computer Use Agents). Choose the metric for the actual retry policy, not for a convenient leaderboard.

Repetition protocol. Notation for repeated success differs in the literature; this article uses the definitions above. Before each repetition, record the state-recovery protocol: initial ERP and memory state, retrieval snapshot, seed and sampling parameters, external API versions, time, and user context. Repetitions using shared memory, state, or an external API may be correlated; state this and do not treat repetitions as independent observations.

Compare agents under prespecified comparable resource budgets: number of model and tool calls, tokens, wall-clock latency, cost, repetitions, and limit overruns. If budgets differ, show the cost-performance frontier and state explicitly which resources produced the result. Otherwise, additional attempts artificially increase success (METR, DeepSeek-R1 evaluation; Kapoor et al., AI Agents That Matter).

An average without sample size, number of runs, and an uncertainty estimate is insufficient (NIST AI 800-3). An uncertainty estimate (for example, a confidence interval, standard error, or bootstrap estimate) reflects only accounted-for sources of variation, such as repeated runs on a fixed suite. It does not correct for bias in an unrepresentative sample, an incorrect oracle, or unknown distribution shift (Measure, AI RMF Playbook; NIST AI 800-2: Initial Public Draft). Bootstrap depends on the resampling scheme (tasks, runs, or trajectory clusters), dependence among observations, and suite representativeness; it does not automatically “add” every source of uncertainty. Averages conceal tails, correlated failures, and degradation on long trajectories; use breakdowns and worst-case scenarios.

Compare usefulness with the current process and a relevant human baseline under the same task setup, recording quality, time, cost, escalations, and corrections (METR, Measuring AI Ability to Complete Long Software Tasks; METR time horizons). A human is not a flawless oracle: the comparison depends on skill, time, tools, and incentives.

Why protections must be tested separately

In the teaching example, three dangerous attempts were blocked. This is evidence that the control worked on three specific requests, but not evidence that the protection covers every path to a prohibited action. Therefore, testing agent behavior is supplemented by testing the access boundaries themselves.

The principle of least privilege limits possible harm: the agent receives only the access needed for its task. It does not establish the correctness of permitted operations; an incorrect draft can still be created through a permitted call. Initiation, approval, and execution should be separated so that one erroneous or compromised entity does not control the entire cycle. This applies general information-security measures; it is not a separate agent certification (NIST SP 800-53 Rev. 5).

Resending a request after a timeout shows why testing rights alone is insufficient. The response may have been lost after the draft was created. An idempotency key or business-duplicate check must link the retry to the same operation; otherwise, a formally correct request will create a second object. Verify the result in the ERP and operation log, not from a single API response code.

To reconstruct events, the log links the run identifier, configuration version, input data, tool requests and responses, access decisions, approvals, and changes to external objects. The log must be protected from alteration and deletion, and its completeness must be checked. Hidden internal model reasoning does not replace observable actions and is not needed as evidence of why an operation occurred.

Logging itself creates a data-disclosure risk. Therefore, minimize inputs and logs, control access to them, set retention periods, provide deletion, and restrict export as part of the audit design, not afterward. Also check data output through tools and in the final response. Provider storage terms, training on data, and data location cannot be inferred from a model name: current terms for the specific service and configuration are required (NIST Privacy Framework).

Stopping must be executable: revoke access, stop new operations, and refer unfinished cases for reconciliation. Not every consequence can be rolled back; a sent attachment or executed payment is not eliminated merely because the process was stopped. Therefore, restoring a known state and managing irreversible consequences must be tested separately.

Finally, the presence of a human in the loop does not guarantee error detection. Approval effectiveness depends on available information, time, and the ability to refuse; people may over-trust automation (overview of automation bias). That is why the example presents the reviewer with cases containing known errors in advance. This test measures how the control works, not whether an “Approve” button exists.

Attack and failure testing

A normal task suite does not cover instructions hidden in external data. Test indirect prompt injection through documents, emails, web pages, RAG content, and tool responses: external data can redirect agent actions (OWASP AI Agent Security Cheat Sheet; NIST AI 600-1). Neither input filtering nor model guardrails alone replaces testing of the data, tools, and permissions actually available. OWASP here is community guidance for threat modeling, not proof of complete threat coverage.

Add red teaming and chaos testing to normal tasks: bypassing restrictions, data leakage, tool abuse, privilege escalation, infinite loops, timeout, stale state, partial execution, unavailable dependencies, and malicious or substituted tools (NIST AI 600-1; AI RMF Playbook). Red teaming depends on the testers’ skills, time, and access and does not provide exhaustive coverage of unknown attacks.

Graduated realism and independent go/no-go

Laboratory measurements may differ from risks in the real deployment context (NIST AI RMF 1.0). Increase realism step by step: sandbox, replay of historical cases, shadow mode, limited pilot, and only then expanded permissions. Preserve prespecified criteria at every stage. Do not grant dangerous permissions before controllability has been demonstrated. A direct production experiment is impermissible if it could cause substantial or irreversible harm.

Shadow mode does not measure every effect of real interaction: users, reviewers, and external systems behave differently when an action is actually executed. Canary and limited-pilot deployments narrow the blast radius but require the same oracle, veto, and logs as preproduction.

Evaluation is a cycle, not a one-time report: pre-deployment TEVV, limited deployment, production monitoring, incident analysis, and revalidation after material changes (NIST AI RMF 1.0; NIST AI 600-1; NIST AI 800-4). The inventory records versions of the model, scaffold, prompts, tools, API schemas, access policies, retrieval sources, grader, and test data.

Change classification. The scope of testing depends on what changed. After a logging change, check record completeness and protection and confirm that execution is unaffected. A change to instructions, the planner, or retries requires testing behavior and prohibitions. For a tool or API, compatibility, permissions, idempotency, and final state matter. After a model change, compare quality and safety again. A change to search and the document corpus requires checking access, retrieval completeness, and resilience to malicious instructions in the data. Expanding permissions requires a new risk analysis and admission decision. Not every change invalidates all earlier evidence. First identify the affected actions and assumptions, then repeat the relevant checks; if the change alters the overall behavior strategy, a local test is insufficient.

Material tests and admission rules undergo effective challenge by competent evaluators who are not the direct developers. Independence may be organizational, technical, and financial; an external contractor is not independent if it depends on the provider or shares the same incorrect assumptions.

Banking validation practice – conceptual soundness, outcomes analysis, ongoing monitoring, effective challenge – is useful as a methodological analogy. Revised Guidance on Model Risk Management dated 17 April 2026 replaced SR 11-7 and expressly excluded generative AI and agentic AI from its scope; the document cannot be transferred as a mandatory regime for agents. If outcomes analysis is used by analogy, it compares actions with subsequent process outcomes, not only the agent’s output with a reference text. Back-testing requires comparable facts; for new processes and rare incidents, its coverage is insufficient.

What evidence to retain for the decision

A go/no-go decision rests on a package that can be rechecked, not on a slide with an average score.

  • System card: system boundary, purpose, users, prohibited states, decision owners.
  • Process map and risk register with residual risk, not only a list of “AI risks.”
  • Evaluation contract: hard constraints, thresholds, escalation, and stop conditions.
  • Test manifest: task stratification, adversarial sets, budgets, and number of repetitions.
  • Version manifest: model, scaffold, tools, IAM, RAG, grader, and snapshot date.
  • Oracle and adjudication protocol for disputed cases.
  • Grader validation on an independent expert sample.
  • Raw traces linked to changes in external systems.
  • Scorecard with components, breakdowns, and uncertainty intervals; veto failures separately.
  • Results of recovery, permission-revocation, kill-switch, and manual-process-transition tests.
  • Comparison with the current baseline under comparable tasks and resources.
  • Untested risks and formal acceptance of residual risk: who accepts it, for what period, and under which review triggers.

Minimum decision record. For a conditional go, separately record the scope of permitted actions; model/provider/scaffold/tools/IAM/RAG/policy version; veto criteria; evidence package; accepted residual risks and their owners; active controls; decision expiry; and triggers for automatic suspension or revalidation.

For material requirements, add a claims-to-evidence traceability matrix:

Requirement Failure mode Control under test Test Oracle Metric Evidence Decision Residual-risk decision
Preparation agent does not execute payments Attempted execution or executed payment Prohibition on calling the execution tool and absence of corresponding permissions Attack on the authority boundary Request log, access decisions, and ERP state Attempts and realized violations counted separately Run identifier and ERP record Deny approval when the specified prohibition is violated Risk owner, period, and review trigger
Do not change master data Bank-detail injection Verification gate and write restriction Email/PDF mutation task Master-data diff + escalation record Unauthorized changes / opportunities Before/after snapshot Go/no-go Accept residual risk or redesign control
Control detects an inserted error Automation bias Evidence-based review protocol HITL challenge task Independent reviewer label Detection rate, false approval rate Review trace and adjudication Control redesign or accept Control owner and date of repeat test

This matrix links a system requirement to a possible failure, test method, metric, and evidence; it does not replace the full test plan.

The production loop connects outcomes, overrides, incidents, drift, and changes in third-party components with rollback, deactivation, and revalidation. Some consequences become visible weeks or months later; without a run identifier and accounting state, the connection between a trajectory and a loss is lost.

Limits of the method

The method does not select a vendor, set universal thresholds, or constitute legal, accounting, or supervisory advice. The article does not define permissible log-retention periods, personal-data requirements, or the applicable regime in a particular jurisdiction. Rare catastrophic errors, selection bias in historical data, and unknown distribution shift remain after any frequency-based suite. The date of relevance for the sources used in this compilation is 18 September 2026; versions of standards, APIs, models, and threats after that date must be checked again.

In the teaching example, the correct decision is to deny the current configuration admission even though it saves time and reaches the threshold on normal tasks. The reason is not an abstract danger of AI but specific failures: insufficient emergency handling and prohibited attempts. This connection between an observation, a prespecified rule, and a decision makes the evaluation auditable. After those causes are fixed, results for the changed configuration will be required; the previous average cannot simply be carried over.
