GH Board Sync

Answer one question with evidence: does the board reflect reality? The dev-loop treats the board as truth, which only works if the board actually tracks the repos. This skill diffs a GitHub Projects v2 board against live repository state — PR merge status, issue state, review decisions, milestones — and reports every item where the two disagree, ordered by how badly the disagreement lies to you.

It is a reconciler, not a board configurator. Board shape (fields, columns, options) belongs to gh-project-board; this skill assumes the canonical shape and compares item state to repo state.
