Bypass Strategies
Bypass strategies determine how a schema field is populated when it should not go through LLM extraction. Each strategy provides a deterministic value without consuming AI credits.
Strategy types
| Parameter | Type | Description |
|---|---|---|
| none | strategy | Field is always left blank. Use for fields you want to skip entirely. |
| constant | strategy | Field is set to a literal value you specify (e.g. "USD", "pending"). |
| generator | strategy | Deterministic value generators: deterministic-id (hash-based ID) or context-fallback (derive from other fields). |
| reference | strategy | Look up a value from a reference table using a key_expression to match against uploaded reference data. |
When a
generator strategy fails to produce a value, the field falls through to LLM extraction as a safety net. Strategy values are normalized via generator mappings in Phase 4 of the pipeline.
