Interface: StructuredSig

A best-effort, lossy decode of a SCRIPT structured <Sig> into typed dosing components. Every component slot is always present and tagged SigFieldProvenance, so the surface is uniform and a consumer can see which fields are coded, derived, or absent.

Safety contract. The free-text sigText is the source of truth and is preserved verbatim; the structured view is additive and clearly flagged lossy (see "../common/warnings".SCRIPT_WARNING_CODES.SIG_STRUCTURED_LOSSY). The two are never reconciled: when structured dosing and the free text disagree, both are surfaced as-is. An ambiguous structured dose is never collapsed into a confident value (see "../common/warnings".SCRIPT_WARNING_CODES.SIG_AMBIGUOUS_DOSE).

Properties

readonly duration: SigField

Duration of therapy.

---

hasStructuredData

readonly hasStructuredData: boolean

True when at least one component decoded to a non-"absent" value.

sigText?

readonly optional sigText?: string

The free-text SIG (<SigText>), verbatim: always the source of truth.
