Why

Attendees enter Meeting Assistant from several paths: calendar metadata, accepted recording prompts, workflow actions, screenshot OCR, speaker identity updates, and summarizer add-attendee tools. Today those paths can normalize display names, but they cannot apply local transformation rules such as trimming company suffixes, replacing aliases, or cleaning attendee strings consistently.

What Changes

• Add an attendee_added workflow trigger that runs whenever Meeting Assistant adds an attendee to a meeting note.
• Allow attendee_added triggers to filter the added attendee with full equality, substring, or regex matching.
• Expose attendee.name to workflow conditions and Razor templates.
• Allow set_property to update attendee.name during attendee_added events, mirroring transcript-line transformation.
• Apply attendee transformations to attendees added by metadata import, prompted-start metadata, workflow add_attendee, screenshot OCR, and summary/workflow editor agent tools.

Impact

• Workflow engine, rules schema validation, and workflow documentation.
• Attendee write paths in recording metadata, screenshot OCR, summary tools, and workflow actions.
• Behavior tests for workflow transformation and representative attendee-add sources.
