feat(sweep): daily stranded-work detector for remote branches and local trees - #138
Merged
Conversation
…al trees One scheduled job that asks whether work is going stale anywhere we own, following the default-branch-sweep pattern of one issue rewritten in place. - remote detector (hosted-safe): branches that are not the default branch, have no open pull request, and have been quiet past --stale-days are listed as stranded; queue/dependabot machinery and fresh branches stay quiet - local detector (--local-root): bin/oa-fresh ported so clones behind origin, unpushed commits, and uncommitted files land in the same issue; duplicate clones of one remote are marked instead of double-counted; a runner without workspace visibility says so instead of implying the trees are fine - sync dispatch input fast-forwards clean default-branch clones only, using bin/oa-fresh's exact safety rule, and refuses loudly on any runner without OA_SRC_ROOT; nothing else in this job mutates anything 20 offline classifier tests cover the fire and stay-quiet conditions plus real-git scratch-repository tests proving sync cannot touch dirty or feature-branch trees.
Copies the default-branch-sweep self-test setup; a bare python -m pytest has no pytest module on the hosted image.

bin/oa-fresh --syncfound 32 local clones behind their origin carrying unpushed or uncommitted work. Stale-tree misreads have produced four confident wrong findings this year.oa-freshanswers the local question but nothing schedules it, and no cross-repository detector watches for stranded remote branches at all. This repository already owns the multi-repo registry and files one issue per day from two other scheduled sweeps.Validation
