On 6 October 2026 the pre-push hook's site build fetched the live downloads index (0.3.14 since 17:47Z) and rewrote site/downloads.json and the stamped pages in five worktrees that had nothing to do with the release, as uncommitted edits to tracked files. A plain build and the hook now read live and warn when the snapshot lags; the ship step refreshes it with the flag and commits it. tools/ci/no-foreign-tree-writes.sh fails a script that builds a path from a worktree name, a glob over Projects or a worktree-list loop that writes; the eight absolute defaults into the shared checkout are listed as warnings until they move to env-only defaults. The journey, bench and index rebuilt from the merged tree.
