## Prompt

Enable Ruff enforcement of the shared 69-column Python source limit in
Modden, Piker, and Tractor. Add a TODO for a later changed-line token/AST
checker covering project rules Ruff cannot express.

## Response

Configured Ruff's formatter/lint line length to 69 and enabled E501. Added a
follow-up TODO for boolean layout, local annotation placement, docstring
quoting and rationale, and symbol-qualified technical prose.

> `git diff HEAD~1..HEAD -- ruff.toml`

The configuration parses successfully. Existing Tractor package/test debt is
1,469 E501 diagnostics; it was reported rather than reformatted implicitly.
