 - **The act-runner of the gitea instance only supports actions up to `node20`.** Anything newer fails with `The runs.using key in action.yml must be one of: [...], got node24`, which is why the Flutter sdk is unpacked from the official archive instead of through `subosito/flutter-action` (that one caches through `actions/cache@v5`). Check the `runs.using` of an action before adding it.
 - The Flutter version is pinned in three places (`FLUTTER_VERSION` in both build workflows, `ARG FLUTTER_VERSION` in `ac_web/Dockerfile`) and must be kept in sync.
 - Steps run with `working-directory: ac_web`, but `upload-artifact` paths are relative to the repository root.
+- **The act-runner executes `run:` with sh (dash), not bash.** A script with `set -o pipefail` fails immediately with `Illegal option -o pipefail`, so the scripts stay posix (`set -eu`, no `[[ ]]`, no arrays) and pipelines are split where the exit code of the *first* command matters.
 - **`actions/upload-artifact` must stay at `@v3`.** `@v4` bundles `@actions/artifact` v2, which aborts with `GHESNotSupportedError` whenever `GITHUB_SERVER_URL` is not `github.com` -- on this instance it is the gitea host, so the check fires before any request and cannot be worked around on the server side. `@v3` uses the older artifact api gitea implements.
 - The workflows are read from the tag the release points at, so they have to be committed **before** the release is created.
 - Artifacts and the built files carry the tag name (`github.ref_name`); the docker image is pushed as the tag, as `latest` and as the short sha.
