New map + RAG entries for the vault subsystem; sequence gate, lineage
merge, gate diff-base, CI guard, playwright MCP, dispatcher prefilter,
backup sidecar, and the 300/100 budget reflected across docs/map,
docs/rag, and CLAUDE.md; stale claims fixed (agent-ux 'no extra tools',
old budget defaults). No redirects needed — nothing publicly published
moved.
