quality sweep
The rule already said "write a characterization test before refactoring" but not what one is or how many to write per unit. Two additions close that.
testing.md's "Adding Tests to Existing Untested Code" now defines a characterization test as recording what the code actually does, not what it should (Feathers' assert-wrong-read-the-real-value recipe), and requires the same Normal/Boundary/Error set as any unit rather than one happy-path capture. The reason is the useful part: on a characterization test the negative and boundary cases are the bug-finders, because untested legacy code is weakest at the empty input and the missing upstream, and pinning what it currently does there writes the wrong behavior down where it becomes a visible bug. A pinned case that turns out to be a bug graduates from recording current behavior to asserting correct behavior. In-unit bugs fall to this set. Composition bugs need a functional test.
The refactor-for-testability section gains the framing that when the untestable code is legacy you're hardening, extracting the pure core is the hardening, not a detour around it. A function you can't characterize without mocking tmux or git can't be refactored safely, so "needs too much mocking" is the signal to reshape it, never a license to skip the boundary and error cases.
code-quality.org's passes claim to preserve behavior, so it now states the precondition that makes that true: on untested scope, a characterization net comes first, or "behavior-preserving" is an assertion the green suite can't actually verify.

Every org document an agent writes carried `#+AUTHOR: Craig Jennings & Claude`. No template stamps that line. Agents copy it from a neighboring file, so one stray header propagates through everything generated afterward.
My own repos tolerate the co-author line. Employers whose policy is that work product carries employee names alone do not. An `#+AUTHOR:` line survives conversion into docx, a wiki page, or a PDF that reaches a customer.
I rewrote the header to `Craig Jennings` across the workflows, templates, specs, and design docs. The rule now lives in commits.md, so the next generated document starts correct rather than inheriting the mistake.
Archived session logs keep their original headers as a record of what happened. The two Codex-authored design docs keep their byline, because Codex wrote them and relabeling would be a false attribution rather than the removal of one.

A thin orchestrator that runs the behavior-preserving quality passes over a scope of existing code in order: /refactor, then readability-audit, then it surfaces the :refactor: tasks readability filed and any deferred /refactor findings. It leaves /simplify out, since that works the current diff rather than existing code.
