Learnings from F58 3-way model comparison (Sonnet/MiniMax/Haiku):
- Read-only test gates: filesystem enforcement (chmod a-w) because
prompt instructions are insufficient — MiniMax edited tests 7x,
Haiku rewrote entirely, only Sonnet respected constraints
- Model selection table: Sonnet minimum for constrained implementation,
Haiku/MiniMax viable for review and test-writing
