# 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. 2. **Enumerate PRs**: List all PRs to merge. For each, fetch the latest HEAD. 3. **Create temporal branch**: Fetch latest and branch from the remote base tip. ``` git fetch origin git checkout -b temporal/<timestamp> origin/<base> ``` 4. **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. 5. **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. 6. **Validate temporal branch**: Once all PRs are merge
