Syncing Main Branch

Syncing Main Branch (Deprecated Reference)

This workflow is excluded from active discovery but retained for explicit local compatibility. Operate on the current repository and preserve the branch, commits, and files being left.

Workflow

1. Inspect tracked and untracked state, branch, and HEAD:

git status --porcelain=v1 --untracked-files=all
git status --short --branch
git symbolic-ref --quiet --short HEAD

Stop on any local change; do not stash, commit, discard, or carry it automatically. If HEAD is detached, record it and inspect containing refs. Stop until an otherwise reflog-only commit is preserved with a user-chosen branch or tag.

2. Resolve main exactly.

   • Use local refs/heads/main when it exists.
   • If absent, create tracking main only when exactly one intended remote main is clear: git switch --no-overwrite-ignore --track -c main <remote>/main.
   • Stop if the remote is ambiguous, main does not exist, or another worktree owns it. Do not substitute another branch or bypass worktree protection.

3. Switch with ignored-file overwrite protection when needed:

git switch --no-overwrite-ignore main

4. Verify main tracks the intended upstream, fetch its configured remote, then fast-forward only:

upstream_remote=$(git config --get branch.main.remote)
git rev-parse --abbrev-ref 'main@{upstream}'
git fetch "$upstream_remote"
git merge --ff-only --no-overwrite-ignore 'main@{upstream}'

Stop on missing or unexpected upstream, authentication failure, divergence, ignored-file collision, or non-fast-forward. Do not rebase, reset, force, delete files, change upstream, or delete the previous branch.

5. Verify git status --short --branch and git log -1 --oneline --decorate. Report the active branch, before/after object IDs, upstream, and whether it advanced. “Already up to date” is success and requires no commit.
