Verify This

Verification is not a recap. It proves or disproves a specific claim with repeatable evidence.

When To Use

The user asks "verify this", "prove it works", "did this fix it", or "show me the evidence".
A bug fix needs a before/after repro.
A UI, CLI, API, performance, or memory claim needs measurement.
A test passes but the user-visible behavior still needs confirmation.

Do not use this for vague claims like "the code is cleaner". Ask for a measurable claim first.

Workflow

Restate the claim in falsifiable form: condition, metric, and threshold.
Pick the smallest local surface that can disprove it.
Capture a baseline from the old state: merge base, parent commit, failing branch, or current broken repro.
Capture treatment from the changed state with the same command, data, warmup, and environment.
Compare raw artifacts: numbers, screenshots, terminal transcripts, HTTP responses, profiles, heap snapshots, or test output.
Return exactly one verdict:
```
VERIFIED
```
,
```
NOT VERIFIED
```
, or
```
INCONCLUSIVE
```
.

Local Surfaces

Code behavior: focused unit/integration tests or a minimal repro script.
CLI/TUI behavior:
```
control-cli
```
, terminal transcript, or demo recording.
UI behavior:
```
control-ui
```
, screenshots, accessibility snapshots, or browser traces.
API behavior: local HTTP/RPC request and response diff.
Performance: same-machine baseline/treatment timings or CPU profiles.
Memory: heap snapshots before and after the suspected operation.

Artifact Layout

When safe to write artifacts:

text

/tmp/verify-this/<claim-slug>/
├── claim.md
├── timeline.md
├── baseline/
├── treatment/
├── diff/
└── verdict.md

If artifacts may contain sensitive code, prompts, screenshots, HTTP bodies, or heap data, keep only the minimal inline evidence unless the user agrees to disk storage.

Verdict Rules

```
VERIFIED
```
: baseline and treatment differ in the predicted direction, by the claimed threshold, with no obvious confound.
```
NOT VERIFIED
```
: the behavior is unchanged, moves the wrong way, or misses the threshold.
```
INCONCLUSIVE
```
: no valid baseline, noisy signal, failed measurement, or an environment difference invalidates the comparison.
