Data flow

The browser sends a user message to /api/chat via NDJSON stream.
The server route sanitizes input (PII), logs with correlation IDs, and creates or resumes a Pi session.
The Pi server module invokes Amazon Bedrock through a circuit breaker.
Streaming events (start, delta, tool, done, error) flow back to the client.
The client hydrates messages from the Pi session file on reload and opens supporting resources/workspace panels on demand.
Supporting endpoints expose models, resources, workspace files, sessions, and health checks.
Durable agent context lives in agent-workspace/, including project memory, plans, artifacts, and workspace-installed Pi resources.
