Walkthrough

This PR fixes an issue where unauthenticated chat sessions created via MCP would be marked as PRIVATE with no owner, resulting in 404 errors when accessed. The fix makes chat visibility conditional (PRIVATE when authenticated, PUBLIC otherwise) and refactors error handling in the chat streaming APIs.

Changes

Cohort / File(s)Summary
Chat Session Visibility Fix
packages/web/src/app/api/(server)/chat/blocking/route.ts		Made chat visibility conditional based on authentication: PRIVATE when a user is present, PUBLIC otherwise. Enhanced error handling in streaming path to convert non-ServiceError exceptions into ServiceErrorException with INTERNAL_SERVER_ERROR.
Error Handling Refactoring
packages/web/src/app/api/(server)/chat/route.ts		Externalized error handling via new onError callback parameter in CreateMessageStreamResponseProps interface and createMessageStream function, replacing internal errorHandler logic with plumbed callback invocation.
Documentation
CHANGELOG.md		Added Fixed entry documenting the resolution of session links being accessible to unauthenticated users in ask_codebase MCP calls.

Walkthrough
This PR fixes an issue where unauthenticated chat sessions created via MCP would be marked as PRIVATE with no owner, resulting in 404 errors when accessed. The fix makes chat visibility conditional (PRIVATE when authenticated, PUBLIC otherwise) and refactors error handling in the chat streaming APIs.
Changes
Cohort / File(s)Summary
Chat Session Visibility Fix
packages/web/src/app/api/(server)/chat/blocking/route.ts		Made chat visibility conditional based on authentication: PRIVATE when a user is present, PUBLIC otherwise. Enhanced error handling in streaming path to convert non-ServiceError exceptions into ServiceErrorException with INTERNAL_SERVER_ERROR.
Error Handling Refactoring
packages/web/src/app/api/(server)/chat/route.ts		Externalized error handling via new onError callback parameter in CreateMessageStreamResponseProps interface and createMessageStream function, replacing internal errorHandler logic with plumbed callback invocation.
Documentation
CHANGELOG.md		Added Fixed entry documenting the resolution of session links being accessible to unauthenticated users in ask_codebase MCP calls.
