Is main green in the repos the gardener watches, and is the gardener working?
A main commit with no post-submit result is a hole a culprit can hide in.
No red range in any repo the gardener watches.
From the last 100 tree-status commits, back to ; older changes are not read.
A proposed revert waits on the App and the ledger; a revert lands on its own only in a repo listed in auto_land_repos.
Caps: at most 10 reverts created per 24 h across all repos. Build breaks: at most 10 created a day; in a repo listed in auto_land_repos, at most 4 a day land on their own, and only when the culprit is under 6 h old. Test failures: at most 10 created a day, never landed on their own. A culprit is verified with and without it first.
