ART-557 · Index/Benchmark Administrator Lineage Family
Record Index Constituents
Gives an index's constituent set, as of a stated date, its own citable execution_hash: the starting point ("what was in the index and why") that every downstream weighting or rebalance artifact cites rather than re-declaring. Accepts a supplied list of constituents (security, name, sector, country), a free-text description of the eligibility criteria applied, and the selection universe size, and attests that this exact declared set exists under this exact declared criteria. First entry of the Index/Benchmark Administrator Lineage family, alongside the forthcoming weight-computation, rebalance-evidence-pack, and correction nodes.

What this does NOT prove
Every constituent row and the eligibility-criteria description here are supplied by you and merely asserted: this tool performs zero index-provider or market-data lookups (zero-egress, no network calls of any kind, never a live index-data feed). It attests that a declared constituent set exists exactly as stated, selected under the stated criteria. This is never a verification that the criteria was correctly applied against underlying market data. A restated constituent set cites the prior artifact's execution_hash via the standard OpenChainGraph supersedes field: no separate status registry. EU BMR and SEBI benchmark-administrator citations below are informative context only.
The declared constituent set, eligibility-criteria description, and selection universe size are digested together into this artifact's execution_hash. A restated set for the same index and date is a new artifact that cites this one's execution_hash via the top-level supersedes field: there is no reverse link and no status registry; supersession is discoverable only from the newer artifact.
⚠ DECISION-SUPPORT DRAFT. Not a methodology verification, not a live index-data feed, not a regulatory filing. Constituent and criteria inputs are supplied and asserted only.
