Ra Code

A1 (document integrity) + A3 (document typing) inputs.

Supplying this runs the document front-door BEFORE anything else: A1.1 security triage fails CLOSED — any non-accepted disposition is a terminal block — and A3's stamp for program_namespace becomes the A7 source role, so the role is DOCUMENTED rather than asserted at the gate. Omit it and the pipeline behaves as it always has: no document gate, and A7 uses the gate evidence's own source_role.

A4.13 modality evidence — the observed facts A4 DETERMINES the encounter's modality from, and that A5/A7 then resolve program eligibility against.

Absent this bundle A4 sees an empty evidence set, and the project pack's presume_in_person_absent_telehealth knob turns that silence into in_person_face_to_face. So a caller with a telehealth encounter had no way to say so, and the gate's modality rule was applied to a presumed modality rather than a documented one.

Evidence is GATHERED here, never guessed: A4 reads exactly these values and derives nothing on its own. In particular narrative_* are things the note SAYS, not conclusions drawn from what it omits, and audio-video is never assumed when a telehealth encounter does not state which it was.

A5/A6/A7 encounter-gate inputs — where RA validity actually lives.

Supplying this runs the real gate (A5 typing → A6 provider binding against the CMS list → A5 modality-eligibility → the A7 stamp) and ROUTES on the stamp: unusable and blocked_remediable are terminal blocks and are never coded; evidence_only is coded but no diagnosis enters the submission lane; only eligible_for_submission proceeds normally. Omit it and no encounter-level gate runs at all — which is what every request to this endpoint did before this field existed.

D3→D8 score-layer inputs. On a compute_raf run these complete the raw V28 score into the actual payment RAF: D5 normalize → D6 blend → D7 the CY2026 MA coding-pattern reduction. Every value is an OFFICIAL effective-dated CMS artifact the caller supplies — a missing normalization factor is a typed block, never an implicit 1.0 — and the result is labeled an INTERNAL projection, never the CMS-reported official factor.

Absent this bundle the pipeline stops at the raw score and payment_raf stays null, which is what it did for every request before this field existed.
