Actions Taken

1. Wrote 2 integration guides (pixelesq-mcp, landlens-one-mcp) following the recordwire guide shape.
2. Live-probed both endpoints over JSON-RPC initialize: Pixelesq returned 401 with OAuth protected-resource metadata and exact scopes; LandLens returned 401 with bearer realm LandLens and protected-resource metadata.
3. Updated catalog index.md (last-updated line, top sweep section, docs-links tail block). Catalog now 648 servers (+534 guides).
4. Fixed two unquoted source values from the Sep 11 evening sweep (recordwire-mcp, clauseai-mcp) flagged by the repo frontmatter gate.
5. Stamped .last-sweep and committed the sweep to corpusiq-docs main.
