Autoresearch Finalize

Present the proposed grouping to the user:

Proposed branches (each from merge-base, independent):

1. **Switch test runner to forks pool** (commits abc1234, def5678)
   Files: vitest.config.ts, package.json
   Metric: 42.3s → 38.1s (-9.9%)

2. **Tune worker count and timeouts** (commits ghi9012, jkl3456)
   Files: test/setup.ts
   Metric: 38.1s → 31.7s (-16.8%)

Wait for approval before proceeding.

Step 2 — Write groups.json and Run

Write groups.json:

{
  "base": "<full merge-base hash>",
  "trunk": "main",
  "final_tree": "<full hash of current HEAD>",
  "goal": "short-slug",
  "groups": [
    {
      "title": "Switch to forks pool",
      "body": "Why + what changed.\n\nExperiments: #3, #5\nMetric: total_time 42.3s → 38.1s (-9.9%)",
      "last_commit": "<full hash of last kept commit in this group>",
      "slug": "forks-pool"
    }
  ]
}

Key rules:

• last_commit must be a full hash. Expand from jsonl short hashes with git rev-parse.
• No two groups may share a file. The script validates this and fails if violated.

Then run:

bash <SKILL_DIR>/finalize.sh /tmp/groups.json

The script creates one branch per group from the merge-base, verifies the union matches the original branch, and prints a summary with all branches, cleanup commands, and any ideas from autoresearch.ideas.md.

On creation failure: rolls back (deletes branches, restores original branch, pops stash). On verification failure: exits non-zero but leaves branches intact for inspection.

Step 3 — Report

After the script finishes, report to the user:

• Branches created and what each contains
• Overall metric improvement (baseline → best)
• Show the cleanup commands from the script's summary output

Edge Cases

• Only 1 kept experiment: One branch is fine — don't force splits.
• Overlapping files between groups: The script fails with an error naming the file. Merge the overlapping groups and retry.
• Non-experiment commits on the branch: Skip them — only process kept experiments from the jsonl.
