Software Evidence in a Minute

Verification

Checking a claim against evidence—distinct from generating the claim in the first place.

In one sentence

Verification is the act of testing whether a claim matches available evidence under an explicit method.

Why it matters

Agents generate claims cheaply. Verification is the scarce skill that keeps merges and metrics honest.

How it works

  • Restate the claim precisely.
  • Choose a verification method (diff inspection, test, metric query, manual probe).
  • Execute the method and record the outcome.
  • Accept, reject, or narrow the claim based on the outcome.

Example

Claim: “Rate limiting is enabled for /login.” Verification: read the middleware wiring at the current commit and send a burst request in a staging environment with logging. If either check fails, the claim is unverified.

What this proves

Verification proves only that a specific claim was checked with a stated method at a stated time.

What this does not prove

One successful verification does not prove the claim holds forever, in all environments, or against future changes.
