Highlights

This release pairs with fsb-mcp-server v0.9.0 to ship the implicit visual session contract. The two-step session lifecycle is gone. Every action tool call now carries the visual session signal natively, the overlay dismisses itself after sixty seconds of silence, and an is_final: true hatch is available for explicit immediate clear.

What's new

• Implicit field bundle on every action tool call: visual_reason (a short human-readable string) and client (an allowlisted label such as Claude, Codex, Cursor, Gemini).
• Sliding sixty-second auto-dismiss for the visual overlay, persistent across MV3 service-worker eviction via chrome.storage.session and chrome.alarms.
• New typed errors surfaced from the MCP server: VISUAL_FIELDS_REQUIRED, BADGE_NOT_ALLOWED, TOOL_REMOVED.

What changed in the extension

• Lifecycle ticks land in chrome.storage.session keyed by mcpVisualSession: and are replayed after service-worker wake.
• A chrome.alarms death timer with the mcpVisualDeath: prefix clears stale overlays on a sliding sixty-second window.
• Ownership gates from v0.9.60 (TAB_NOT_OWNED, AGENT_CAP_REACHED) take precedence over the new field-bundle gate at the dispatch chokepoint.

Compatibility

Existing extension users see no change in installation flow. Refresh the extension on chrome://extensions to pick up the new lifecycle. Pair with [email protected] for the full contract; older MCP server builds (v0.8.x and earlier) will not emit the new payload sidecar but remain functional under the deprecated explicit lifecycle.
