A pipeline doc commit carries the review document and the rebuilt
INDEX.md; while the task waits, dev receives other tasks' documents with
their own INDEX.md, and the rebase of the branch conflicts in the index
every time. 24.09 this bounced green #617, #618, #629, #642 to S6.
scripts/rebase-generated.mjs: shared rebase helper. At every stop, if ALL
conflicting paths are docs/reviews/INDEX.md (or paths the caller
resolves itself), the index is rebuilt from the directory in the stop
tree, staged, and the rebase continues; any other path aborts and
returns the full list. CLI exit 3 = refusal with paths on stdout.
Wired into process.yml «Привести ветку к dev» (helper taken from dev via
git archive; conflict/conflicts outputs, lease, ref wait and
--commit-if-stale kept), merge-candidate rebaseOnto (claude[bot]
identity, --commit-if-stale kept) and rebase-on-dev.mjs (index next to
GENERATED_ROOTS; bundle still dev copy + rebuild).
