Flag that you were left out of a meeting you should have attended

A meeting that touched your work happened without you, and you want to flag it without sulking. This rewrites your message three ways, assertive that states the exclusion had an impact and asks to be included next time, diplomatic that raises it gently, and a middle version, so you make the point at the right pitch.

I was excluded from a meeting that was directly relevant to my work and I want to raise it professionally.

Who organised or attended: {MEETING_ORGANISER_OR_ATTENDEES}
What the meeting covered: {MEETING_TOPIC}
Why my inclusion mattered: {RELEVANCE_TO_MY_ROLE}
My draft message: {MESSAGE_DRAFT}

Rewrite this message in three versions:
1. Assertive: states clearly that the exclusion had an impact and asks to be included going forward
2. Diplomatic: frames it as wanting to contribute, curious whether the exclusion was deliberate
3. Neutral: notes the gap in information, asks how to stay informed without assigning blame

Label each version clearly. Keep all three under 150 words each. End with one sentence on how seniority dynamics should affect tone.
