+# Bauer v2 Implementation Log
+
+_Coordination file for the multi-agent implementation of specs 001 and 002._
+
+---
+
+## How to use this file
+
+Each sub-agent appends its entry to the **Branch Log** section below. You (the reviewer) read through these entries in order to understand what was implemented in each branch, then check out each branch and review it as a PR against the previous.
+
+**Review guide:**
+1. Start with the **Branch Chain** section — it gives you the full sequence.
+2. For each branch: read the log entry, check out the branch, review the diff.
+3. Each branch is independently reviewable as a PR against its parent.
+

+## Reviewing a Branch
+
+To review branch N:
+
+```bash
+git checkout <branch-name>
+git diff <parent-branch> -- .
+```
+
+Or on GitHub, open a PR from `<branch-name>` into `<parent-branch>`.
+
+Each branch is a clean, independently reviewable unit. You can review them in any order, but reviewing in the listed order (1 → 12) builds understanding correctly.
