Fiscal Dataset Status

Dataset or provider	Status	Evidence / limitation
NCM	IMPLEMENTED	Imports the official Siscomex JSON endpoint configured as `NCM_DATASET_URL`; each version retains SHA-256, source URL, download time, act, update label, and row count.
CEST	IMPLEMENTED	Imports only DOM tables in Annexes II-XXVI from official CONFAZ `CV142_18`; each raw HTML revision retains SHA-256, source URL, download time, act, version, and row count.
CFOP	NOT_AVAILABLE	No authoritative dataset integration is configured in Mission 02.
CST/CSOSN	NOT_AVAILABLE	No authoritative rules integration is configured in Mission 02.
cClassTrib	DISCOVERED	Kept as an input/output placeholder only; no source or decision engine is claimed.
IBS/CBS	NOT_AVAILABLE	No verified official calculator is configured.
RTC calculator	NOT_CONFIGURED	The hub returns no RTC result and never fabricates fiscal values.

The CEST result is an informational official source match, never an automatic fiscal determination.
