Git Utility Requirements Specification
======================================

1. Naming Conventions
---------------------
- Filenames use dot-segment format.
- No underscores in any filenames.
- Directories use lowercase.
- Internal functions use CamelCase.

2. Exit Behavior
----------------
- Exit keys must be x or q.
- Numeric exit options prohibited.

3. Directory Layout
-------------------
bin/
config/
docs/
code/
arch/
data/chunks64/
audit/

4. Bundle Rules
---------------
- Bundles: docs.64, code.64, arch.64
- gzip + base64
- Decoded files: docs.txt, code.txt, arch.txt

5. Metadata Rules
-----------------
- Stored in git.utility.meta
- Must include version, description, timestamp

6. Audit Rules
--------------
- Naming audit
- Menu audit
- Structure audit
- All read external rule files

7. Reusability Rules
--------------------
- Rules stored in config/rules.*
