DORA RoI GLEIF Pre-Submission Preflight Pack

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.

DORA (EU) 2022/2554 Art. 28/30 Register of Information build, GLEIF-hardened: the RoI template set feeds a GLEIF snapshot digest and relationship-consistency check for each LEI-bearing counterparty in the register, composed into one preparation-aid evidence pack with a named-human attestation closure. Preparation aid only: not a submission, not a filing, not a determination that a submission is complete or accurate, and not a statement that any regulator has reviewed or would accept this output.

Chain Stages · 4 Steps
1 ROOT node
Constructs and cross-validates the RoI template set. The caller identifies every LEI-bearing counterparty (provider) in the resulting providers[] array to drive Stage 2/3, one GLEIF check pair per counterparty.

2 D1 · ×N per counterparty node
GLEIF Snapshot Digest art-599-gleif-snapshot-digest
Run once per LEI-bearing counterparty from Stage 1. Produces lei/lei_checksum_valid/source_sha256/captured_at/snapshot_captured for that counterparty's gleif_snapshot slot in Stage 4.

3 D2 · ×N per counterparty node
LEI Relationship Consistency Checker art-600-lei-relationship-consistency
Run once per counterparty from Stage 1, over that counterparty's pasted GLEIF Level-2 relationship record set. Produces records_assessed/consistent/violation_count for that counterparty's lei_relationship_check slot in Stage 4.

4 TERMINAL node
DORA RoI GLEIF Pre-Submission Evidence Pack art-601-dora-roi-gleif-preflight-pack
Terminal stage, page-less shard. Links the Stage 1 artifact by execution_hash + tool_id (never the raw dataset), composes each counterparty's Stage 2 + Stage 3 results, rolls up all_snapshots_captured and any_relationship_violation, and records the management-body attestation closure, producing the final preparation-aid evidence pack.
