 - Ten additional unreferenced implementation plans, setup records, and deferred stubs moved byte-identically to `archive/planning/legacy/`. `agent-reflection-loop-PRD.md` was excluded because a MACP test names its intended canonical path; the WebUI/Fleet bridge draft was excluded because it remains authority-gated.
 - Of 111 quarantined scratchpads, 94 had no current path/name consumers and no coupled local Markdown links; they moved byte-identically to `archive/work-records/`. Seventeen remain quarantined with their control-document, source/test fixture, mission/evidence, or KBN-101 dependencies.
 - The two Matrix/MACP RFCs were explicitly draft, unreferenced, and link-free. They moved byte-identically under `archive/planning/matrix-macp/`; the archive index points to the canonical channel page that records Matrix as unimplemented.
+- The npm prerelease-lane and storage-abstraction designs had no current consumers or local links. They moved byte-identically under `archive/planning/designs/` with explicit source/test verification boundaries.
