Diff / API snapshot review

Compare two JSON API snapshots before release notes

Start with two API snapshots, compare changed and added paths, and use the expected summary as the release-review target.

Reproducible trace

Identify a changed limit, a changed state, and one added feature flag.

How to use this workflow

Download or copy the input. The fixture is synthetic and designed for this exact operation.
Run the operation. Use the linked JSON All-in-One tool, or reproduce the operation in your own environment when the syntax matches.
Compare the expected output. The expected result is the acceptance target for this fixture, not a general product guarantee.

Notes and limits

The expected summary is intentionally compact; the interactive diff UI can expose more context around each path.
Use synthetic snapshots only; do not paste secrets into public examples.
