Internal meta-tag codes stamped on FHIR resources by Soigneur ingress pipelines. These are machine-managed tags (not user-facing) that support ingress idempotency and provenance. The codes are display-less markers: the per-resource VALUES ride in the cc-ext-content-hash / cc-ext-icu-push-hash meta extensions, because a value in a tag's display is not round-trip-safe — FHIR R4 fixes tag identity at system+code and lets servers merge tag displays on update (fire-arrow-server issue #713; ADR 0055 as revised).

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system https://fhir.soigneur.coach/fhir/CodeSystem/cc-meta defines the following codes:

CodeDisplayDefinition
content-hash Content hash Marker for resources stamped with a content hash. The SHA-256 itself is carried in the cc-ext-content-hash meta extension (ADR 0055, as revised); pipelines compare the stored hash against a newly-computed one and skip the PUT when they match, avoiding version churn.
icu-push-hash Intervals push fingerprint Marker for ServiceRequests carrying an Intervals push fingerprint. The SHA-256 of the last Intervals.icu events/bulk upsert body is carried in the cc-ext-icu-push-hash meta extension (ADR 0081, as revised); the plan-push worker skips the live Intervals call when the fingerprint still matches.
