Sundial

In Action

Refill your coffee and watch Sunny work.

Memory

Continue what you started, without re-explaining.

You open Sundial on a Tuesday. Sunny already knows you ran ablations Monday, that two failed (CUDA mismatch), and that Maya commented on the third.

Yesterday: ran ablations 1-5 on baseline_v2

ablation_2: failed (CUDA mismatch, see cell 14)

ablation_3: Maya flagged the loss curve (thread)

ablation_4: best F1 so far (0.87)

Todo: rerun ablation_2 on the smaller batch?

Shared with Devon. "Fixed dim mismatch in cell 12. Re-ran cells 12–18. Loss looks healthier."
