From 10383b40b7c0c1b03c1e2e0bbb8c513b375e3a36 Mon Sep 17 00:00:00 2001 From: root Date: Thu, 16 Apr 2026 22:31:54 -0500 Subject: [PATCH] =?UTF-8?q?Staffing=20day=20simulation=20=E2=80=94=20multi?= =?UTF-8?q?-agent=20stress=20test=20on=2010K=20Ethereal=20workers?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 5 contracts, 16 positions, 10K worker pool. Four agents: Matcher (SQL + vector hybrid), Communicator (LLM SMS drafts), Verifier (fact-checks against golden data), Analyzer (RAG intelligence questions). Results: - SQL matching: 16/16 positions filled, ZERO hallucinations. Every worker's name, role, city, state, certifications, and reliability score verified against the golden dataset. - SMS generation: 16/16 messages drafted with correct worker names. - RAG intelligence: retrieval returns semantically similar but structurally wrong workers (wrong state, wrong archetype) because vector search can't do structured filtering. LLM correctly reports context limitations — doesn't hallucinate beyond retrieved chunks. Key finding: SQL path is production-ready. RAG path needs hybrid SQL+vector routing — SQL for structured constraints (state, role, cert, reliability), vector for semantic similarity. That's the architectural gap to close.
