Notes

STUB pending clinical co-lead signoff (CHARTER §6.1 — dev-mode-exempted). Per the Disease narrative, nonfunctioning pituitary adenoma is managed with surgery only for mass effect / visual compromise; asymptomatic non-compressive NFPA is appropriate for observation with surveillance imaging and is deliberately not modeled as an active-therapy Indication in this KB (mirrors the existing "active surveillance, not a separate indication" pattern used in ALGO-GI-NET-ADVANCED-1L). "visual_field_deficit", "optic_chiasm_compression", and "pituitary_mass_effect_symptoms" are new free-form finding keys — no engine-side data-collection wiring confirmed to exist yet for these keys; the `condition:` free-text leaf in the trigger preserves the clinical criterion regardless of finding wiring status, consistent with existing KB precedent (e.g. RF/algorithm notes in ALGO-RCC-METASTATIC-1L for unwired finding keys).
