+### Task ID Resolution
+
+`auto_merge` resolves the task ID from the branch name first (e.g.
+`DEVX-12-fix-foo` → `DEVX-12`), falling back to the `.taskid` file
+for branches without a task ID prefix. If both exist and disagree,
+a warning is printed and the branch task ID is preferred.
+
+**When creating a new branch from an existing branch**, the `.taskid`
+file may be stale (it contains the old branch's task ID). Either:
+1. Update `.taskid` to match the new branch's task ID, or
+2. Delete `.taskid` — the branch name is the primary source of truth
+
+### Workflow `auto-merge` Job and `always()`
+
+When `auto-merge` depends on a job that can be skipped (e.g.
+`molecule-tests`), the `if:` condition MUST include `always() &&`
+at the start. Without it, Gitea Actions skips `auto-merge` when any
+dependency is skipped, even if the condition explicitly allows
+`result == 'skipped'`.
+
+```yaml
