| 3 | +# Move a branch that must NOT simply be deleted into PyAutoGut, then remove it |
| 4 | +# from the repo it came from. |
| 5 | +# |
| 6 | +# WHY THIS IS NOT THE SWEEP. branch_sweep deletes branches whose content is |
| 7 | +# provably already in main — spent work, recoverable from main forever. This is |
| 8 | +# the opposite case: a branch worth keeping precisely BECAUSE main does not |
| 9 | +# contain it. The motivating example is PyAutoHands' `master`, 442 commits from |
| 10 | +# 2021-2022 orphaned by a 2023 "history reset", sharing no ancestor with main |
| 11 | +# and pinned by no tag. Deleting it would have made those commits unreachable. |
| 12 | +# |
| 13 | +# So the two must never share a code path: the sweep's question is "is this |
| 14 | +# already in main?", and this workflow's is "is this safely in the Gut yet?". |
| 15 | +# |
| 16 | +# THE ORDERING IS THE WHOLE POINT. Archive, VERIFY the ref exists on the Gut |
| 17 | +# remote, and only then delete. Not archive-and-assume: a push that reports |
| 18 | +# success but lands nothing, or lands under a different name, would otherwise |
| 19 | +# be followed by an irreversible delete. The verification is a separate |
| 20 | +# `ls-remote` against the Gut, not a reading of the push's own exit code. |
| 21 | +# |
| 22 | +# The archive itself is delegated to `pyauto-gut archive`, not reimplemented |
| 23 | +# here. PyAutoGut is the organ that holds and voids; the Brain only drives it |
| 24 | +# (the Heart ↔ vitals template). Reimplementing the push would put the Gut's |
| 25 | +# namespace convention in two places. |
| 26 | +# |
| 27 | +# Filing the condemned.md entry is deliberately NOT done here — that index is |
| 28 | +# Mind state, written by the hygiene conductor's condemn pass with a human |
| 29 | +# deciding the transit clock. Some material (original project history) should |
| 30 | +# be held indefinitely rather than swept, and that is a judgement, not a step. |
