From e05d7d1e1a828e98d73b7981cc9f209e4d06997c Mon Sep 17 00:00:00 2001 From: Timmy Date: Sat, 22 Aug 2026 20:57:04 +0000 Subject: [PATCH 1/3] test: expand deterministic symptom escalation regression suite Issue #21 (epic #5). Prove model behavior can never suppress or soften urgent symptom handling. - Pin the six authoritative red flags, their canonical order, and the exact urgent copy as read-only exports; hostile provider output cannot reassemble it. - Grow the positive text matrix from 24 to 56 pinned clinical phrases across all flags (bloody stool, dark-red/black descriptions, severe abdominal pain variants, vomiting tenses/slang, fever phrasings, inability to pass gas) and pin 27 idiomatic negatives that must not escalate (threw up my hands, yellow fever history class, black tea). - Authoritative boundary suite: every red-flag phrase and confirmed ledger symptom/note intercepts chat with zero Hermes calls; malicious/missing provider replies cannot weaken the deterministic response; truthy junk symptoms can neither fabricate nor suppress escalation. - Wiring suite: the single chat gate screens urgency before any agent turn in both service and browser code; detection stays centralized in the frozen domain pattern table. RED evidence: URGENT_MESSAGE unexported, 9 matrix misses (bleeding from my rectum, bloody stool/poop, severe pain in my abdomen), 8 false positives (I threw up my hands, feverish about the election). GREEN: 87/87 npm test, syntax/diff gates clean, 0 vulnerabilities, browser suites pass with zero /api/agent/chat calls on urgent input.
