## `@uswriting/exiftool@1.0.9` — stderr vs warnings

We do **not** use a `patch-package` diff here: the published `dist/*.js` files are one minified line each, so unified diffs are huge and hard to review.

Instead, `patches/patch-exiftool-stderr.mjs` runs on `postinstall` and removes two **documented** guard strings:

| Guard | Role |
| ----- | ---- |
| `READ_STDERR_GUARD` | After exit 0 on **read**, fail if stderr is non-empty |
| `WRITE_STDERR_GUARD` | After exit 0 on **write**, fail if stderr is non-empty |

See the script for exact literals and upstream context.

When upgrading `@uswriting/exiftool`, run `npm install` and confirm the script still finds both guards (or update the script for the new bundle).
