Notes.

Field notes from the Athena Systems team. Justin (appraisal SME) writes about practice — what kicks reports back, which rules matter when, what a reviewer is actually looking for. Darin (CTO) writes about the system — how the rule engine works, what the cryptographic audit chain actually proves, why we made the design choices we did. Alternating weeks.
