+   Reminder: `.github/workflows/release-signature-reminder.yml` runs after the
+   Release workflow and every 6 hours. While the latest release has a bundle but no
+   `.minisig` it opens the issue `Sign release vX.Y.Z (minisign)` (assigned to the
+   owner), re-pings it every 12 h and closes it itself once the `.minisig` is
+   uploaded. Reminders for older releases are closed automatically, as superseded
+   (`uteke upgrade` only installs the latest release) or when their `.minisig`
+   appears. "Latest" follows GitHub's definition (by creation date, the same release
+   `uteke upgrade` installs), so a backport patch published after a newer minor
+   supersedes the newer release's reminder. Only issues and comments authored by the
+   Actions bot or the owner are acted on. It signs nothing and holds no key. Test its
+   script with `bash scripts/tests/release-signature-reminder.test.sh` (stub gh, not

 - **`ORT_LIB_PATH` pointing at a directory no longer leaves uteke without embeddings (#1459)** - the Homebrew shims exported the `libexec` directory (v0.19.0 onwards), `dlopen` failed on it, and every such install silently stored memories FTS5-only (`embedding_written: false`, `uteke verify` MISMATCH). A directory that holds the platform library (`libonnxruntime.so`, `libonnxruntime.dylib` or `onnxruntime.dll`) is now accepted with a warning; a directory without it is a clear error that says to set the library file. The tap fix is codecoradev/homebrew-tap#10 (`brew update && brew reinstall codecoradev/tap/uteke`). Docker and the release tarballs were not affected.
 - **CLI log lines no longer corrupt `--json` output (#1461)** - the console log layer wrote to stdout, so any WARN or ERROR (for example a failed embedding) was printed in front of the command's JSON and `json.loads(stdout)` failed. Console logs now go to stderr; the log file and the command output are unchanged.
