repo-device-synclisted

# repo-device-sync Keeps one repo consistent across devices that may commit concurrently. The failure this prevents: starting work on stale state, or pushing over a commit another machine landed mid-session. The discipline is always the same - **fetch before trusting anything, diff before pulling, re-fetch before pushing, verify after.** ## Phase 1 - Assess (always first) ```bash git status --porcelain # uncommitted local work? git fetch origin # never reason about origin without this git status -sb # ahead/behind for current branch git branch -vv # ahead/behind for all tracked branches ``` Report per tracked branch: in sync / ahead N / behind N / diverged (N and M). Surface uncommitted changes before doing anything else - they change what is safe below. ## Phase 2 - Reconcile inbound (behind) 1. Show what is coming: `git log --oneline HEAD..origin/<branch>` and a summarized `git diff HEAD...origin/<branch> --stat`. 2. **Deletion pre-flight - run before every pull.** An incoming commit that untracked newly-ignored paths arrives as a real working-tree deletion, and afterwards those paths are ignored, so the loss leaves no trace anywhere the default views look: ```bash git diff --name-status HEAD origin/<branch> \ | awk '$1=="D"{print $2}' | git check-ignore --stdin ``` Any output means this pull deletes files that will then be invisible. Stop, show the list, and ask before pulling. It is recovera
