Ownership chain not yet documented in the available data (licensed corporate-ownership database, licensed supply-chain database, SEC filings, LEI registry; as of 2026-07-06). The chain may extend further once additional ingestion runs complete; absence here reflects coverage at this snapshot, not a documented apex.

Notes
DayOne-operated. Existence + 20 MW capacity anchored to DayOne's own ground-breaking announcement (28 July 2025) + Singapore EDB press release referencing 20 MW DC-CFA approval; tier-2 attribution for facility-level disclosure (DayOne is private post-deconsolidation; no SEC filing covers SG1 directly). Coordinates set to Singapore city-center per anti-fabrication discipline; precise Jurong East address is 21 Jalan Buroh.

No flags found across the chain (BIS Entity List, designation-cascade closures, or compute-threshold reporting obligations) as of 2026-07-06. Cascade closures evaluated: 0.
No ownership-change events documented in the available data for any entity in this chain over the last 5 years. Events draw from a licensed corporate-ownership database’s deal records (M&A, buyout, divestiture, asset sale, JV formation); coverage is strongest for private US/EU transactions and partial for state-owned-enterprise restructurings or non-Western private deals. Subsequent ingestion runs may add events here.

The walk for DayOne SG1 Singaporestarts at the operator org id (or owner org id when no operator is recorded) and climbs upward through the unified affiliate graph, normalized to trace child-to-parent relationships. At each hop, the highest-authority parent edge wins (priority ordering: SEC EDGAR / 10-K / LEI registry > licensed corporate-ownership database > licensed supply-chain database > BIS / Federal Register > licensed affiliate graph). Confidence and recency break ties.
The walk terminates on (a) a node with a public-filing-grade ancestor edge — a SEC filer, an LEI-registered listed entity, or a 10-K-disclosed parent — (b) a government entity, (c) a 10-hop limit, or (d) a detected cycle. When termination is not at a public filer or government, the panel labels the chain's end-state as opaque beyond that point. Opacity is reported, never implied.
Per-source confidence (licensed corporate-ownership database): HIGH for Parent / Subsidiary edges; MEDIUM for JV and AFFILIATE edges. Known limitations: (1) shell companies with undisclosed principals terminate the public-record walk; (2) recent transactions reach the panel after the database's weekly refresh; (3) cross-jurisdiction private holding structures may carry intermediate hops that are not in any ingested source. Each row carries an edge-level as of date so freshness is auditable per hop.
Two further caveats are inherent to how the walker and the underlying data compose. The walker selects a single highest-authority parent per hop, so JV or multi-parent ownership structures collapse to one displayed path; alternate parents exist in the ingested sources but are not surfaced on this card. And some licensed-database edges encode parent-of relations against entity-resolved stub IDs whose display name reflects a sub-entity (a business unit, an acquired-then-renamed line) rather than the canonical parent — when a chain reads structurally surprising, the per-row source citation is the authoritative reference, not the chain's narrative shape.
Computed at: 2026-07-06. Walk depth observed: 1 hop. Sources combined: Scrutica facility record + licensed corporate-ownership database + SEC CIK cross-reference + LEI registry + (where applicable) licensed supply-chain database + Federal Register designation closures. The licensed databases are held under subscription and not redistributed; per-hop labels name no vendor.
