The three sources disagree:

| Source | Platform team engineers |
|---|---|
| orgchart.md | 8 engineers (plus manager R. Osei) |
| wiki.md | 6 engineers (noted "last updated Q1" — likely stale) |
| budget.csv | 7 (headcount; unclear whether this includes the manager) |

No single authoritative answer. The orgchart is likely the most current at 8 engineers; the wiki is explicitly outdated. The budget's "7" may reflect a mid-year figure or a different definition of headcount. I'd recommend confirming with R. Osei or HR.

Full harness trace — baseline · 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.
