docs(skill): ask for a version rollback before reproducing or reverting

Follow-up to #3026/#3028. The sub_filter was blamed for a download regression
and reverted; the reporter's own rollback to 1.5.3, which predates the filter,
showed identical behaviour and the revert was closed unmerged. Records the
sequencing lesson, the ruled-out layers, and the registry-layer rig.

 cannot be self-verified — a service that reads its environment only at start makes an env-var fix
 unproven until the add-on restarts, which needs the user or `ha-cli` with their agreement. If you
 cannot restart, the change is **Assumed**, not Verified, and must be reported that way.
+
+## When your change is blamed for a regression, ask for a version rollback first
+
+PR #3026 added an nginx `sub_filter` to the `filebrowser_quantum` ingress vhost. Right after it
+merged the user reported Download had broken — the file opened inline instead of downloading — and
+confirmed it still worked on the add-on's direct port, which serves `direct.conf` and carries no
+`sub_filter`. That made the filter the only ingress-side change in the update, so PR #3028 reverted
+it. Meanwhile every measurement said the filter was not involved:
+
+- the shipped bundle's Download action builds an `<a href>` and clicks it, and never calls
+  `window.open`, which is all the injected shim overrides;
+- the shim's own predicate, evaluated live in the running app, returned false for the download
+  URL, the `inline=true` raw URL and the public-share download URL;
+- the download response through the vhost was **byte-identical** with and without the `sub_filter`
+  (`Content-Disposition: attachment` intact, `Content-Length` unchanged), for `text/plain` and for
+  the `text/html` case the filter actually scans;
+- upstream's frontend download code is unchanged from v1.5.0-stable to v1.5.4-stable; Supervisor's
+  ingress proxy forwards `Content-Disposition` (`_response_header` drops only `Transfer-Encoding`,
+  `Content-Length`, `Content-Type`, `Content-Encoding`); and the ingress panel's iframe carries no
+  `sandbox` attribute, so downloads are not sandbox-blocked.
+
+The measurements were right. The user then rolled their add-on back to **1.5.3**, which predates the
+filter, saw the identical behaviour, and the revert was closed unmerged.
+
+**The lesson is about sequencing, not about who was right.** "Works on the old version, breaks on the
+new one" is the only cheap experiment that actually isolates a shipped change, and only the reporter
+can run it. Ask for it *first* — before building a reproduction, before opening a revert. It costs
+them one add-on downgrade and it either confirms the regression or, as here, redirects the whole
+investigation. A revert is the fallback for when they cannot roll back, not the opening move.
+
+Two corollaries:
+
+- **Do not let a clean local reproduction settle it either.** Being unable to reproduce is not
+  evidence of absence, and the reporter watching it fail on their own instance outranks it. Both
+  sides of that needed the rollback to resolve.
+- **`build_from: <image>:latest` means every merge ships an upstream version bump too**, so "it
+  broke when your PR landed" never implicates the diff on its own. Record which upstream version
+  each add-on image was built from — the registry config blob's `created` timestamp, the resolved
+  manifest digest, and the binary's version string. Here: add-on 1.5.3 was built 2026-08-28 23:29
+  UTC from upstream v1.5.3-stable, 1.5.3.1 on 2026-08-30 06:00 UTC from v1.5.4-stable
+  (`sha256:e549e1a9…`). If you do use a revert as the experiment, both builds must resolve the same
+  upstream digest or it proves nothing:
+
+  ```bash
+  T=$(curl -s "https://auth.docker.io/token?service=registry.docker.io&scope=repository:<repo>:pull" | jq -r .token)
+  curl -s -H "Authorization: Bearer $T" \
+       -H "Accept: application/vnd.oci.image.index.v1+json" \
+       "https://registry-1.docker.io/v2/<repo>/manifests/latest" \
+    | jq -r '.manifests[] | select(.platform.architecture=="amd64" and .platform.os=="linux") | .digest'
+  ```
+
+Worth building anyway, because it is reusable and needs no dockerd: a reproduction rig made **out of
+the published image's own layers**. Pull the manifest and blobs from the registry with `curl` + `jq`,
+untar them in order, then run the extracted binary through the image's own musl loader
+(`root/lib/ld-musl-x86_64.so.1 ./filebrowser`) with the real `http/dist` next to it. Put the add-on's
+rendered `ingress.conf` in front of it, and a second nginx in front of that to strip the
+`/api/hassio_ingress/<token>` prefix the way Supervisor does. That gets the real frontend, the real
+backend and the real vhost under a browser — everything except Supervisor itself. Plain `tar` does
+not interpret whiteouts, so a file a later layer deletes (`.wh.<name>`) or a directory it marks
+opaque (`.wh..wh..opq`) survives into the reconstructed rootfs; check with
+`tar tzf <layer> | grep '\.wh\.'` and reach for an OCI-aware unpacker if any turn up.
