[Bug] Fable 5 Safeguards False Positive on Healthcare Domain Software Development
Bug Description
False positive: Fable 5 safeguards flagged a benign web development request.
Context: Laravel 12 / Livewire 3 job board for the dental industry
(dentallas.hu). The session involves normal CRUD/business logic:
company profiles, CV access purchases, tax-number-based company
identification (Hungarian NAV registry lookup).
The flagged message contained no security, biology, or chemistry
content. The likely trigger is domain vocabulary (dental/medical
terms, personal data handling), which is standard for any
healthcare-adjacent SaaS. Session language: Hungarian.
Impact: mid-session fallback to Opus 4.8 makes Fable 5 unusable
for this project. Request: tune the medical/bio classifier to
distinguish healthcare-domain software development from actual
biology capability requests.
