Actions Taken

1. Wrote 7 integration guides (attensira-mcp, stayingapi-mcp, stocks-team-mcp, 0xinsider-mcp, aiworker-data-mcp, moysklad-mcp-ru, upcampo-mcp) following the ddmarketer guide shape; all 7 PASS the per-guide validator on the first pass.
2. Live-probed 2 endpoints over JSON-RPC: DDMarketer (keyless, 4 tools - confirms the Sep 4 guide) and aiworker-data (keyless initialize + tools/list, 20 tools, server v0.2.0).
3. Fetched 2 OpenAPI contracts (stocks.team: 47 operationIds; 0xinsider: 57 operationIds) for exact tool tables.
4. Verified moysklad repo (MIT, 2 stars, pushed 2026-09-12) and stayingapi manifests (server.json, smithery.yaml, glama.json).
5. Updated catalog index.md (last-updated line, top sweep section, docs-links tail block). Catalog now 659 servers (+545 guides).
6. Frontmatter gate green (4,228 files scanned, all valid).
7. Stamped .last-sweep and committed the sweep to corpusiq-docs main.
