Smart Merge to Temporal Branch

Merge multiple PRs into a temporal integration branch for validation before merging to base.

Process

1. Detect base branch: Identify the default branch via git remote show origin or repo conventions.

1. Enumerate PRs: List all PRs to merge. For each, fetch the latest HEAD.

1. Create temporal branch: Fetch latest and branch from the remote base tip.

`` git fetch origin git checkout -b temporal/<timestamp> origin/<base> ``

1. Determine merge order:

• If the user specifies an order, use that.
• Otherwise, compute dependency/topological order (if PR B depends on PR A, merge A first).
• If PRs are independent with no clear ordering, present the list and ask the user to confirm or reorder before proceeding.

1. Sequential merge with conflict handling — for each PR in order:

a. Attempt git merge --no-ff <pr-branch> into the temporal branch. b. If merge succeeds cleanly, continue to next PR. c. If conflicts occur:

• Analyze each conflict using difft and codebase context.
• Apply resolution using structural understanding (prefer base for formatting, PR for logic).
• If a conflict cannot be resolved with confidence, abort (git merge --abort), stop, and report the conflict with both sides and a recommended resolution.

d. After each successful merge, run available build/test commands to catch regressions early.

1. Validate temporal branch: Once all PRs are merged, run full build/test suite if available.

1. Report results: Present the validated temporal branch to the user. Do NOT merge into base automatically — only advance base if the user explicitly requests it.

1. Abort conditions — stop the queue and report if:

• A conflict cannot be safely auto-resolved.
• A post-merge build/test fails.
• A PR has been superseded or closed.

The temporal branch is abandoned: git checkout <base> — base remains untouched.

Output

Report for each PR: merged successfully, conflicts resolved (with details), or blocked (with reason). Include the temporal branch name for user review.
