Got it — the platform team has twelve engineers. I'll keep that in mind.

For the org chart, put the platform team at eight people.

final reply
Quick flag: you earlier said the platform team has twelve engineers. Do you want the org chart to show eight (a different headcount — e.g., excluding the manager and some non-engineers), or should I update the team size to eight overall?

Full harness trace — flagOn · seed 3

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
