Docs Cleaner

Documentation goes wrong in two different ways, and they need different work.

It rots. Something changed — a port, a path, a procedure, a decision — and the docs still describe the old world. The field's name for this is documentation rot or version drift: artifacts fall out of sync one at a time until people stop trusting the set.

It sprawls. The same topic accumulates three files, each partly right, none authoritative.

Both trace to one root cause: a fact was written down in more places than it was defined. Everything below follows from fixing that.

Core principle (governs both modes)

Critical evaluation before deletion. Never blindly delete. Analyze each section's unique value before proposing removal. The goal is reduction without information loss.
