+  polling; existing cursors survive the pause.
+- Refused thread-event handoffs retain their cursor without freezing the global
+  listing watermark or conditional header. After five failed passes, a
+  persisted terminal retry record prevents the same notification update from
+  restarting the cycle or repeating its drop notice, even across restart.
+  A refused `checks.completed` stays on its head/TTL schedule, with no retry
+  limit and no drop notice.
+- Acceptance by either granted event egress counts as delivery. Declining a
+  push no longer makes the poller resend an accepted channel message (or the
+  reverse); the sibling egress's decline is warned about and treated as final,
+  so the message is not re-sent on that egress.

+- **Contributor mode** (#5): with `GITHUB_TOKEN_FILE` instead of the App variables, the server authenticates
+  with a personal access token (classic) and gets its events from `GET /notifications` (the threads its user
+  takes part in), so a resident can follow its own pull requests and threads in repositories where the App
+  isn't installed. Notifications from repositories outside `GITHUB_REPOS` are dropped, and `GITHUB_REPOS`
+  may span several owners. A first start delivers what GitHub notified from one poll interval before it. A
+  thread the server stops reading after repeated failures gets one `thread.read_failed` event on its channel
+  (tags `github:read-failed` and `chat:mention`). The webhook listener is refused in this mode. A
+  notification whose reason is `review_requested` arrives as `pull.review_requested`, and the server looks
+  up the checks on the heads of the token user's open pull requests, the 100 most recently updated, so a
+  settled result arrives as `checks.completed`, as in App mode. `GITHUB_BOT_LOGIN` is optional in this mode: unset, it is the token's
+  login.
+- **`search_issues`**, in both modes, drops `user:`, `org:` and `owner:` qualifiers from a query as it already
+  dropped `repo:`, since GitHub widens a search to each of them, and leaves out any result from another
+  repository on the page, saying how many.
+- **A polled merge** is tagged `github:pr=merged` beside `github:pr=closed`, as a webhook delivery's is, in App
+  mode's repository poll too: the issues endpoint's row says whether a pull request was merged. Otherwise App
+  mode is unchanged.

+- `github.actions` feature set: `list_workflow_runs`, `dispatch_workflow` and
