Code Review

This pull request updates the message center data in index.html by adding a new post, updating the status of several existing posts to 'completed', and removing older entries. The review feedback correctly identifies a mismatch in the agent audience key ('researcherAnalyst' instead of 'firstParty') in the newly added post, which would prevent it from being displayed under the First-Party Agents tab, and provides a code suggestion to fix it.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Mismatch in Agent Audience Key

There is a mismatch between the audience key used in the message center data ('researcherAnalyst') and the key used in the React component's state/configuration ('firstParty').

In index.html:

• The state defaults to 'firstParty' (line 198).
• The agentTypes configuration defines the key as firstParty (line 239).
• The filtering logic (line 759) checks post.agentAudience.includes(selectedAgentKeyForContent).

Because of this, any post with 'researcherAnalyst' in its agentAudience will never be displayed under the First-Party Agents tab.

To resolve this permanently, please update the generator script scripts/update-message-center.js to map/output 'firstParty' instead of 'researcherAnalyst'. For this PR, you can manually update this entry as shown in the suggestion.
