CbCR Annual Publish

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

OECD BEPS Action 13 Country-by-Country Report build with internal consistency gates and anomaly-pattern surfacing in one artifact. gate_status and anomaly_flags are recorded per the §27 Human Accountability vocabulary; a PUBLIC release additionally requires a dual_control(2) preparer/tax-officer gate before disclosure; both recorded now, enforced once HA-RETRO-1 wires runtime gating. Never a filed submission.

OECD Country-by-Country Report Builder art-472-cbcr-builder
Builds the CbCR XML schema skeleton, runs consistency checks, surfaces anomaly_flags, and computes gate_status, final stage. PUBLIC export_mode release requires a dual_control(2) preparer + tax-officer sign-off (recorded, not yet runtime-gated) and review_required routing on any anomaly_flags before disclosure.
