	# Nothing used to watch the documentation. The 2026-08-30 addons/ → features/
	# rename left eight dead paths in contract docs (rest-api.md, pfst-v2-spec.md,
	# the RFC log) and nobody noticed for four days, because no grep runs on
	# docs/. This one does: every relative link in every Markdown file has to
	# resolve to a file in the tree. Stdlib Python, no network, seconds.
