Symbol library + active learning
The org's symbol library is the recognizer's vocabulary. It grows as estimators confirm or correct detections from the review queue.

Two kinds of rows
- SymbolDefinition — canonical 'this is what an X looks like' entry, scoped to a trade and a status (draft / active / deprecated)
- SymbolAnnotation — instance of a symbol detected on a sheet (DETECTION) or hand-marked as ground-truth (GROUND_TRUTH)
Promotion path
Detection → confirmed in review queue → becomes ground-truth → bumps the linked SymbolDefinition's training_sample_count → the next training run promotes the definition's confidence prior.
Library vs org-private
Org-private symbols stay in your org. The cross-org library is vetted by platform staff; your definitions can be nominated for promotion but never auto-shared.
