# Evidence and access

> What a recording proves, where evidence lives, and who can read it.

## Artifact reference

| Artifact                     | Use it to understand                              | Limitation                                                   |
| ---------------------------- | ------------------------------------------------- | ------------------------------------------------------------ |
| Semantic flow and steps      | The intended journey and executed actions.        | Intent alone does not prove a checkpoint passed.             |
| rrweb events                 | Historical DOM changes and interactions.          | A replay is not a live application.                          |
| Screenshots                  | Appearance at recorded moments.                   | One image does not establish behavior between captures.      |
| Playwright trace             | Browser execution and diagnostic context.         | Availability depends on successful capture.                  |
| Console and network evidence | Errors and requests observed during the run.      | Correlation alone does not establish the cause of a finding. |
| Reproduction recording       | What happened when an affected flow was repeated. | An inconclusive reproduction remains unresolved.             |

Choose the relevant browser and viewport before interpreting an artifact. A
responsive preview made by resizing historical DOM is not a recording at the new
size. Truthful coverage at another size requires another execution.

## Hosted access

Review artifacts are private evidence in Cloudflare R2, with review metadata in
D1. The hosted viewer checks workspace access before serving evidence. Links are
also subject to expiration, deletion, and consistency with the selected target.

Signing in does not grant access to every review. If an artifact is unavailable,
check the workspace, review, and target before requesting another run. The
[troubleshooting guide](/docs/site/troubleshooting) covers common cases.

## Local access

Local PR reviews write to `.diffraction/local-reviews/` in the Diffraction
checkout. Local artifact routes are restricted to loopback development access
and are disabled in production. A hosted deployment cannot read recordings from
your local filesystem.

## Evidence and diagnostics

PostHog supports product analytics and correlated diagnostics. It is not the
system of record or customer review evidence store. Brand styling must not tint,
blur, distort, or retouch customer recordings.

Retention duration and repository privacy controls remain owner decisions. This
documentation does not promise a retention period that has not been configured.
