+## The daily workflow
+
+[`.github/workflows/upstream-watch.yml`](../.github/workflows/upstream-watch.yml) runs
+`comment --json` every day at 14:00 UTC (`0 14 * * *`) and on demand (`workflow_dispatch`, with a
+`post` switch to preview in the job summary only). It uses the workflow token (`issues: write`),
+which reads public upstream repositories, and no model: the script decides the text. When there
+is something to post it checks that the body is non-empty, starts with the code block and has a
+`checked-at` line, posts it on the ledger issue, and reads the posted length back. While any
+`released` line carries `branch=` (whether posted today or earlier), it then removes and re-adds
+the `upstream-dispatch` label on the ledger issue, which fires the dispatch routine; a signal
+lost to a failed step is sent again the next day, and the routine skips work already done.
+
+A blind run fails the job. GitHub sends a failed scheduled run's notification to the user who
+last changed the `cron` line, and disables a public repository's scheduled workflows after 60
+days without repository activity
+([`schedule`](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows#schedule)).
+A partial failure shows only in the job summary and in the comment's last sentence, and keeps the
+start where it was; a thread that fails every day therefore keeps the window growing until it
+reads again or its entry is retired, so a "Could not check" sentence that repeats needs a look.
+On a pull request that changes the watch, a read-only `preview` job runs the same check without
+posting.

+## The dispatch routine
+
+A claude.ai cloud routine on this repository makes the code change a released fix allows. It
+does not read upstream repositories (a cloud session reaches only the repositories attached to
+it). A GitHub trigger on the `upstream-dispatch` label of the ledger issue fires it. The maintainer
+creates the routine and its trigger, and that authorizes exactly its writes in this repository:
+`upstream/*` branches and draft pull requests. It never comments, upstream or on the ledger, and
+never merges.
