+3. **Wait for CI on the published commit, this way.** One runner serves the repository, so the
+   jobs of a push run **one after another**, never side by side: CI's `verify` job (about
+   **8 minutes**) and `pwsh` job (about **3 minutes**) first, then the second run a push to
+   `main` starts - `release.yml`, preceded by the `Converters` check - which waits `queued`
+   until CI is done and then takes about **1 minute**. From the push to the last green run that
+   is about **12 minutes** (measured 10.5 to 13 minutes, October 2026); a second run still
+   `queued` while CI works is the runner's order, not a hang.
 
    - Read the runs for the published commit's SHA through the authenticated Gitea connection
      `ENVIRONMENT.md` lists (the Gitea MCP's `actions_run_read`, `list_runs`), right after
      `publish`, to get their ids. **Never anonymously via `curl`:** Gitea answers the Actions
      API with `401 token is required` even for this public repo.
-   - Check again after about 4 minutes (5 with a release job), then once a minute.
-   - **Give up after 15 minutes** and hand the open runs to the user by id and link, rather than
-     waiting on.
+   - Check again after about 11 minutes, then every 2 minutes.
+   - **Give up after 25 minutes** - twice the usual time, so a slow day is not mistaken for a
+     hang - and hand the open runs to the user by id and link, rather than waiting on.
    - Any shell loop that polls instead must **end on the first non-2xx status or missing field**
      and print the raw response. A loop that treats an error as "not finished yet" never ends;
      that happened in the #139 close-out.
