KnowledgeBase extension for EspoCRM: UI on top of the shira-hermes KB of
Israeli National Insurance law, regulations, and circulars.
Three modes:
- חיפוש — Hybrid (pgvector + tsvector) + Voyage rerank-2.5, returns ranked
chunks with heading_path and citations.
- שאל את שירה — Full agent loop; Shira picks up search_insurance_kb as
needed and returns a summary with citations.
- עיון — Browse all active sources. Click a source:
- PDF source (ספר הליקויים, ספר המבחנים, circulars): renders the
original PDF inline via an iframe proxied through the
KnowledgeBasePdf EntryPoint, so the layout/columns/tables are
preserved and Ctrl+F works natively.
- TXT source (חוק הביטוח הלאומי scraped from Wikisource): falls back
to the hierarchical chunk list with RTL styling.
Architecture:
- Controller: KnowledgeBase.php — thin proxy to shira-hermes /kb/*.
- Service: KnowledgeBaseService.php — shared curl plumbing; derives the
shira-hermes base URL from the SmartAssistant integration record so
there is no second admin config.
- EntryPoint: KnowledgeBasePdf.php — streams the PDF inline, wraps the
body in a php://temp stream for setBody, applies a locked-down CSP.
- JS: views/kb/index.js branches on source.original_path; modes wired
through the SmartAssistant fa_IR i18n convention.
Auth model:
- Browser → EspoCRM: session cookie / X-Api-Key (EspoCRM's existing auth).
- EspoCRM → shira-hermes: X-Api-Key from the SmartAssistant integration
(never exposed to the browser).
- Portal users are blocked at both the Controller and the EntryPoint.
