Fork Upstream Sync

Integration main means fork main = upstream/main plus your unmerged commits in linear history (not a merge commit that duplicates feature work).

Prerequisites

Before selecting a path, validate all requirements:

• Tools: require Git 2.30+; require gh only for PR-state checks.
• Access: confirm authenticated fetch and push access to origin, plus fetch access to upstream.
• State: check that the working tree is clean or stashable and that the target branches are not checked out in another worktree.
• Recovery: record the current branch and SHA. If fetch, stash, rebase, reset, or push fails, stop at that command; never continue with stale assumptions.
