Week in review
Every Field Note grouped by the Monday–Sunday week it reports on, then by topic. One page per week, so a week can be read on its own after it ends.

Useful short-term context can be written into model parameters, then used to generate further training.
- Jul 6–12, 20261 noteInference 1
Speculative decoding becomes a runtime scheduling choice because a fixed depth can slow high-batch inference
- Apr 6–12, 20261 noteAgent identity 1
Agent identity is being recast as a short-lived delegation chain, not a reused login
