Second hostile review of 1aadca91 found nine ordinary urgent phrasings
bypassing the deterministic gate at detector and service layers, plus
punctuation-fragile contextual exclusions. Replace the accumulated
narrow regex table with a structured, versioned, frozen urgent-expression
grammar and one shared surface normalizer:
- normalizeUrgentText: case folding, apostrophe unification, contraction
expansion (can't/cant/can not -> cannot, haven't -> have not, ...),
hyphen splitting, punctuation stripping, whitespace collapse
- URGENT_EXPRESSION_GRAMMAR v2.0: per-flag ordered match expressions with
bounded nonclinical anchor exclusions; anchors veto only the occurrence
they sit beside (36-char window), so arbitrary future symptom language
keeps escalating with no continuation-word allowlist
- new RED->GREEN coverage at every layer: 9 review phrases + 5 prior
phrases with tense/plural/pronoun/word-order/case/contraction/
punctuation variants, normalization-equivalence groups, anti-allowlist
continuation sweep (147 combos), grammar structure audit, service
zero-Hermes-call interception, and live-HTTP wiring proof with the
bounded fake adapter (tests/escalation-http.test.js)
Gates: npm test 99/99, check:syntax, check:diff, audit 0 vulns,
staging-deploy 20/20, test:ui/test:photo/test:sleek against this
checkout. No merge, no deploy.
