Deterministic view of the source YAML entity. Clinical authority remains with the cited source IDs and reviewer sign-off state.

Knowledge-base record for audit. Provisional clinical content: this is not a prescription. An oncologist must verify original sources, applicability and review status. Full rules and constraints are in the YAML.

Notes

First clinical-content consumer of §17 Indication.phases[] schema (chunk gi2-c1-flot-periop-gastric-2026-05-08-0900). Sets the gold- standard pattern for C2-C5 chunks (CROSS phasing, Whipple-aware PDAC indications, etc.). Engine routing from `algo_gastric_resectable_*` to this indication is out of C1 scope — flagged for D2 algorithm- extension chunk follow-up. The `recommended_regimen` field is left null intentionally because the periop sequence is multi-modality; consumers should iterate `phases:` rather than dereferencing a single regimen ID.
