Lesson 3 of 3

Prove the risky part

Finish with a small reproducible check and a clear record of what remains uncertain.

Match the proof to the consequence

A low-risk brainstorm may need a quick review. Security, money, health, legal obligations, or personal data require stronger evidence and qualified human judgment.

Increase the proof when the consequence grows

The right verification effort depends on what happens if the answer is wrong.

High stakes need stronger evidence and the right human owner, not a longer AI answer.
  1. Choose the claim

    Select the claim whose failure would matter most.

  2. Choose the evidence

    Prefer official documentation, original data, or observed system behavior.

  3. Run the check

    Use the smallest test that another person can repeat.

  4. Record limits

    State what the test proved and what it did not prove.

Score the risk before choosing a test

Verification should be proportional, not maximal. Estimate how likely the result is to fail, how severe the consequence would be, and how many people or systems could be exposed. A spelling suggestion needs a glance. An access-control rule needs signed-out and cross-account tests because a single mistake can expose private records.

Turn a claim into a reproducible check

Visual explainer

Anatomy of a small trustworthy test

A test is useful when another person can repeat it and understand both the result and its limits.

Diagram, step by step
  1. ClaimState exactly what should be true
  2. Known setupRecord account, version, data, and starting state
  3. Repeatable actionWrite the smallest exact sequence of steps
  4. Expected resultDefine success before observing the output
  5. Observed evidenceCapture logs, response, screenshot, or measurement
  6. Known limitsState what the check did not cover
Relationships

  • Known setupprepare: Repeatable action
  • Repeatable actioncompare: Expected result
  • Expected resultobserve: Observed evidence
  • Observed evidencebound: Known limits
The smallest complete test is stronger than a large vague statement that “everything works.”
  1. Write the claim

    Use one sentence that can be true or false.

  2. Freeze the starting state

    Record the version, account role, input, and configuration that matter.

  3. Define expected behavior

    Decide what you should observe before running the check.

  4. Run and capture

    Perform the smallest repeatable action and save the evidence.

  5. Name the boundary

    List scenarios the test did not exercise.

Test failure paths, not only the happy path

A system may behave correctly for the owner and still fail for everyone else. Negative tests ask what must not happen: a signed-out visitor must not see a private lesson, another account must not edit your record, a repeated payment request must not charge twice, and a failed deployment must not destroy the previous working version.

Visual explainer

Four directions for a stronger check

After the normal case passes, change one boundary at a time.

Diagram, step by step
  1. Expected user and inputConfirm the intended path first
  2. Wrong identitySigned out, different account, or lower role
  3. Bad or missing inputEmpty, oversized, malformed, or repeated data
  4. Dependency failureTimeout, unavailable provider, or partial response
  5. Recovery pathRetry, rollback, and safe error state
Relationships
  • Expected user and inputchange user: Wrong identity
  • Expected user and inputchange data: Bad or missing input
  • Expected user and inputbreak service: Dependency failure
  • Dependency failurerecover: Recovery path
A reliable result remains safe when identity, input, or dependencies change.

Keep an evidence record that stays honest

Weak record

Tested it. Everything works.

Useful record

On version 2.4, a signed-out request to the private route returned 302 to login. A second-account test also failed closed. Admin-role behavior and provider outage recovery were not tested.

The five fields of a useful evidence note
FieldWhat to record
ClaimThe exact behavior or statement being checked
SetupVersion, role, environment, and relevant starting data
ActionRepeatable steps or command
ObservationActual response, measurement, log, or screenshot
LimitCases not covered and questions still open

Put Ask–Inspect–Prove together

The complete reusable AI workflow

Each stage produces the input for the next, and new evidence can send you back to improve the request.

The goal is not blind confidence. It is a visible chain from intention to evidence.
Knowledge check

Check your understanding

Three practice questions. They are not saved to an account or awarded points.

01Which result needs the strongest verification?
02What makes a verification check reproducible?
03After a test passes, what should the record include?
