Unclear The tengu_webagent_mcp_bridge gate returned off for this site's account and for the anonymous baseline; no reading has been taken under this release yet, so its rollout status here is unknown.

What

Headless sessions (used for print mode or the SDK) can now, when a bridge SDK URL is present and parseable, set up something called a 'headless hearth mount' via createHeadlessHearthMount. It's wired up with storage, credentials, the session's bearer token, and configuration for reading the projects binding. This is controlled by a feature gate.

Why

This lays groundwork for connecting headless sessions to a webagent MCP bridge, though it isn't enabled for general use yet.
