Development record

abcd docs lint is unusable inside a target repo without a plugin root: with ABCD_PLUGIN_ROOT/CLAUDE_PLUGIN_ROOT unset it reports plugin_root_status missing and cannot run, so the read-only doc-currency check the prepare-this-repo skill implies is unreachable when onboarding an external repo. Detector: docs lint runs against any repo docs/ given only a cwd (no plugin-root prerequisite), or fails loudly with a one-line remedy per loud-staging. Acceptance: abcd docs lint in a repo with docs/ but no plugin root.
