Brain MCP server-side intake quality gates expanded:
Brain MCP server-side intake quality gates expanded: 5 new regex patterns in contribute.py _OPERATIONAL_DESCRIPTION_PATTERNS hard-block operational descriptions derivable from instruction/config files — agent scope/role descriptions, schedule+category listings, container/agent/server count inventories, all-healthy summaries, timestamp-anchored status snapshots. Combined with SOUL.md anti-patterns (3 new explicit rules). Defense is now 5-layer deep: rotation gate → operational-description gate → dedup/length/specificity → SOUL.md advisory → Librarian nightly prune. This prevents agents from dumping operational state into Brain that belongs in instruction files.
