# Atomic Commits
## Overview
Take a dirty working tree of uncertain provenance and produce a clean, linear sequence of atomic commits where every commit builds, every commit could be reverted in isolation, and `git bisect` will land on a meaningful unit when chasing a regression. The agent does not assume it remembers what changed — it investigates, classifies, groups, then commits.
## Core Principle: The Bisect Test
Every commit must satisfy this test:
> If `git bisect` lands on this commit alone, can the project still build, run its test suite, and be deployed? And does the commit's title accurately describe a single coherent change?
This produces two rules that govern every grouping decision:
1. **Smallest buildable + deployable unit.** Do not split a change so finely that an intermediate commit fails to compile, breaks tests, or leaves an import dangling. A new module and its first caller belong together if the caller would not compile without the module.
2. **No smaller, no larger.** Do not bundle two unrelated improvements just because they touched the same file. Two bug fixes in `auth.py` should be two commits — bisect cannot tell which one introduced a regression if they ship together.
When the two pull in different directions, prefer the smaller commit and add the minimum scaffolding (e.g., a stub, a no-op default) needed to keep the tree green.
## Workflow
### Phase 1 — Survey
Before classifying anything, get a complete picture of the working tree.
