• MutalaaMCP (#4085): Turkish legislation, court decisions and Constitutional Court rulings - geo-niche legal class (LEGAION/Qotien precedent).
• Prior-sweep dispositions respected across the feed and /all repeats: SlateVM, MatPlotLibNet, failecho, loudreader, EU AI Act Compliance #4081, Errand #4082, requisition-audit #4080 - all disposed in the Sep 12 morning sweep; /all page-1 author shells (jpol34, mokhtarabadi, renezander030, vasilicasijarvis, wgd5678, wlsdks, xkqg, 15998194110) and feed repeats from the Sep 11 sweeps.

Actions Taken

1. Wrote 3 integration guides (b2b-creators-mcp, craftstory-mcp, instantreply-mcp) following the recordwire/pixelesq guide shape; all 3 PASS validate-guides.py on the first pass.
2. Live-probed the B2B Creators endpoint over JSON-RPC initialize: HTTP 401 {"error":"unauthorized"} - endpoint live and auth-gated (the listing FAQ's no-auth claim is wrong; probe takes precedence).
3. Verified npm packages (@craftstory/mcp v0.1.3, @instantreply.co/mcp v0.2.0) and both source repos (MIT, pushed 2026-09-12).
4. Updated catalog index.md (last-updated line, frontmatter, top sweep section, docs-links tail block). Catalog now 651 servers (+537 guides).
5. Stamped .last-sweep and committed the sweep to corpusiq-docs main.
