What's new in Saathi Bot
Real updates, performance optimizations, and security patches shipped directly to production.
Dark Mode Accessibility & Contrast Remediation
Comprehensive polish to visual tokens ensuring all text, badges, and code snippets meet WCAG 2.1 AA contrast ratios across both light and dark themes.
- Resolved dark-mode text blending where feature titles (Allowed Domains Whitelist, Theme Launcher, Developer API) blended with dark stone backgrounds.
- Aligned Active Learning cards (Semantic Question Clustering, Zero Hallucination Gate, Unanswered Questions Dashboard) with explicit stone-900 / white color tokens.
- Updated globals.css with automatic media query prefers-color-scheme: dark variable overrides.
Bot Deletion Relational Cascade (9-Table Integrity)
Strengthened organization owner controls with comprehensive relational cascade deletion across the entire PostgreSQL schema.
- Implemented atomic ON DELETE CASCADE covering document chunks, pgvector embeddings, crawled sources, visitor chat sessions, domain whitelists, and active learning logs.
- Added organization ownership authorization checks (403 for regular members, 401 for unauthenticated).
- Verified cascade completion with comprehensive end-to-end integration test suite.
Real-Time Origin Checks & Wildcard Domain Whitelisting
Added strict origin verification to protect customer embed widgets from unauthorized domain hijacking and token theft.
- Added wildcard domain matcher (*.example.com) for multi-subdomain SaaS platforms.
- Built real-time CORS origin testing endpoint in Bot Settings for immediate verification before deployment.
- Enforced strict 403 Forbidden rejection for unauthorized embed domains.
Tenant Isolation Verification & AI Gateway Leak Defense
Hardened PostgreSQL Row-Level Security (RLS) to guarantee complete isolation across concurrent tenant sessions.
- Automated 20x repeated chat cross-tenant stress tests verifying Bot A queries never leak Bot B documentation.
- Added cryptographically salted SHA-256 IP hashing for visitor rate limits without storing plain-text visitor IPs.
- Implemented strict confidence gate: rejects queries with cosine similarity < 0.55 at zero LLM token cost.
Saathi Bot v1.0 General Availability Launch
First public release of the Bring-Your-Own-Key (BYOK) multi-provider conversational AI platform with native Hinglish grounding.
