Review passed. Journal-only PR — clean PM session entry. Good analysis: the governance loop gap (reconcile_page landed without discussion tools, so external agents can act but can't perceive) is a sharp observation and well-prioritized. Pipeline state is accurate, deferred items are explained, and the note about the TS type errors being too small to file separately shows good judgment. No protected files touched, build green.
