v1.7.6

New features

WebMCP support (document.modelContext)

• Full WebMCP spec compliance: document.modelContext polyfill, object-form registerTool, toolchange events, and signal-based unregistration
• TypeScript types for the polyfill and WebMCP surface
• Test suite covering polyfill registration, toolchange dispatch, and signal cleanup

AI Relay Bridge — Gemini support

• Input detection for Gemini's rich-textarea contenteditable component
• Send-button detection via aria-label="Send message" with visibility guard (Gemini hides the send button with a CSS hidden class during generation instead of using disabled)
• Streaming detection covers both "Stop generating" and "Stop response" button label variants

AI Relay Bridge — reliability improvements

• Session locking: relay popup binds to a specific Ontosphere tab; stale-tab messages are dropped
• Fast session discovery via ping rather than waiting for the next poll cycle
• 3-minute batch timeout with partial-result flush when individual tool calls hang
• Incremental injection with pending-count hints for multi-call batches
• Injection guard blocks new polls while a result is being inserted, preventing dropped results
• FhGenie stop-button streaming detection (DismissSquare icon path)
• getGraphState scoped by graph list; unified with canvas summary

SHACL violations

• Violation messages enriched with rdfs:label values for human-readable property and class names
• Improved tooltip readability in the SHACL shapes panel

Bug fixes

• Canvas: Delete key and halo delete button now route through the authoring state machine; nodes no longer reappear after save when deleted via keyboard
• Relay: reverted polling strategy to isAiStreaming() guard after stability regression; added two-poll idle streak requirement before injection to prevent the UUID-echo bug on OWUI
• Relay: strict bidirectional session pairing blocks tabs running old bookmarklet code

Breaking changes

None. The WebMCP polyfill is opt-in and backwards-compatible with the existing window.__mcpTools registration path.
