Nothing derails a claim like a chat thread that will not load. We hardened Valor's chat architecture so conversations keep flowing, even when inputs are messy or the database is under stress.
Highlights
- Schema migration unifies historical and new messages so every thread renders consistently.
- Null-safety guardrails block malformed payloads before they can crash a session.
- Message validation enforces size limits, attachment types, and citation formats.
- Better observability streams metrics into our reliability dashboard for faster incident response.
Why it matters
Chat is the connective tissue for every workflow. These upgrades keep conversations available during peak usage and protect against data drift.
How to test it
- Open an existing conversation with a long history to confirm it loads instantly.
- Send messages with attachments, citations, and structured replies to see validation in action.
- Review the chat reliability dashboard for live uptime, latency, and error stats.
Screenshots to capture
- Chat thread spanning the migration boundary without gaps.
- Validation error toast preventing an unsupported attachment.
- Reliability dashboard panel for chat uptime.
