From 0fa42a0cc34209dc8449622e972dc37a931e7cd7 Mon Sep 17 00:00:00 2001 From: root Date: Thu, 30 Apr 2026 08:03:16 -0500 Subject: [PATCH] multi-coord stress Phase 1.5: shared-role contracts + paraphrase handover MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1 had two known gaps: (1) the 3 contracts had zero shared role names, so same-role-across-contracts Jaccard was vacuous (n=0); (2) the verbatim handover at 100% was the trivial case, not the hard learning test (paraphrased queries against another coord's playbook). Both fixed in this commit. Contract redesign — all 3 contracts now share warehouse worker / admin assistant / heavy equipment operator roles, plus a unique specialist per contract (industrial electrician / bilingual safety coord / drone surveyor — the "specialist not on the standard roster" case from J's spec). Counts and skill mixes vary per region. New driver phase 4b — paraphrase handover. Bob runs qwen2.5-paraphrased versions of Alice's contract queries against Alice's playbook namespace. Tests whether institutional memory propagates across coordinators AND across natural wording variation that Bob would introduce when running Alice's contract. Run #002 result (5K workers + 10K ethereal_workers, 4 demand × 3 coords + paraphrase handover): Diversity (the question J asked: locking or cycling?): Same-role-across-contracts Jaccard = 0.119 (n=9) → 88% of workers DIFFER across regions for the same role name. Milwaukee warehouse vs Indianapolis warehouse vs Chicago warehouse pull mostly distinct top-K from the same population. The system locks into geo+cert+skill context, not cycling. Different-roles-same-contract Jaccard = 0.004 (n=18) → role-specific retrieval works (unchanged from Phase 1). Determinism: Jaccard = 1.000 (n=12) — unchanged. Learning: Verbatim handover 4/4 = 100% (trivial case, expected) Paraphrase handover 4/4 = 100% (HARD case — passes!) Of those 4 paraphrase recoveries: - 2 used boost (Alice's recording was already in Bob's paraphrase top-K; ApplyPlaybookBoost re-ranked to top-1) - 2 used Shape B inject (recording wasn't in Bob's paraphrase top-K; InjectPlaybookMisses brought it in) The boost/inject mix is healthy — both paths are used and both produce correct top-1s. Multi-coord institutional memory propagation is empirically working under wording variation. Sample warehouse worker top-1s across contracts (proves diversity): alice / Milwaukee → w-713 bob / Indianapolis → e-8447 carol / Chicago → e-7145 Three different workers from the same 15K-person population, selected on geo+cert+skill context.
