Introduce the worktree convention the corpus previously lacked: any substantive work stream targeting main — in every mode, autonomous (/boss) and interactive alike — runs in a git worktree on its own branch (issue-N-<slug>), and the branch reaches main only through a user-ratified merge performed by the orchestrator (fast-forward preferred, push covered by the ratification, no pull request). Background sessions were already harness-isolated; this extends the same isolation to the sessions the harness does not guard. The convention depends on worktree.baseRef=head (the default 'fresh' bases branches on origin's routinely-stale tip under the no-autonomous-push discipline), now pinned in conventions.md. boss/SKILL.md gains the run-level mechanics (§ The run worktree): one worktree per run named after the reference issue, entered before the first dispatch; the merge is a user-reserved run-close act; the done-state notify names the branch as the review handle; closes #N fires at merge-and-push time. Iron Law, rollback-sandbox framing, user-reserved-act enumerations, rationalisations, and red flags updated to match. Corollary reconciliations after adversarial review: implement's 'there is no branch' narrowed to 'the loop creates no branch of its own'; specify's auto-signed-commits-on-main heading reworded to ratified-history framing; the sandbox bullets in conventions.md and the CLAUDE.md fragment note the anchor is the run branch's base. The skills meta-repo itself stays exempt (its CLAUDE.md: install symlinks resolve to the primary clone) and direct-on-main.
