#A.10:4.3 SCR / RSCR (Symbol Carrier Registers).

Preface node heading:a-10-4-3-scr-rscr-symbol-carrier-registers:16810

#Content

Every Γ_epist aggregation SHALL emit an SCR: an exhaustive register of symbol carriers materially used in the aggregate, with id, type, version/date, checksum, source/conditions and optional PortionOf (A.14) for sub‑carriers. Every Γ_epist^compile SHALL emit an RSCR: SCR specialised to a bounded context (vocabularies, units) with publication‑grade identifiers and hashes. Why this matters: it prevents “lost sources” during composition and underwrites reproducibility without mandating any specific tool.
