Mission Run Overview
Mission Run: Docs Quality Gate Hardening
Make three docs quality gates fail loud instead of shipping silent drift or gaps.
Issue #3253 catalogued three ways the docs pipeline can pass green while wrong: the slash-command reference can drift from the command registry, the published-page collector can silently under-count when a content subtree resolves empty, and a PR-time link gate can be skipped for deletions outside its paths filter. This mission closes those gaps so contributors and CI catch the problems at PR time rather than post-merge.
