Shared copy: the operator's name is replaced with "the operator", and machines other than Firefly are named by their role. Nothing else is changed.

What is built now

Nothing. The lessons table is empty.

What is missing

Lesson distillation, admission rules and retrieval.

Reviewer's read: Merged into 20; not started

Reconciled into 20 (one store, one call). An evidence point from elsewhere in her system argues for caution: a 09-27 review of her acceptance failures found 95 of 100 were novel, so remembered lessons have little to bite on. The gains are in solving, not remembering.

How it is measured merged

See 20.
