Each site is one Watermark investigation. The page color says what opens; the campus line is the build on the ground — two different clocks.

Corridor entity LEIs (GLEIF)

Verified Legal Entity Identifier (LEI) records for the corridor / RSEI facility parent companies on the watchlist, resolved against the GLEIF registry — the global “who is who / who owns whom” directory. Regenerate with watermark lei.

DatasetGLEIF LEI — AWS Open Data s3://gleif (golden copy)

The S3 bucket is the bulk golden copy (millions of records, refreshed ~3×/day). For a small watchlist we use the REST API; raw responses cache under the git-ignored data/cache/gleif/, and only the curated YAML here is committed.

Method (litigation discipline)

  • Every LEI is pinned and fetched by exact 20-character ID — never a fuzzy name match — so the committed record can’t drift onto the wrong legal entity. INEOS USA LLC, for instance, is pinned to the Delaware entity (549300TWZ86K81VO8O17) by exact legal-name match — distinct from the Belgian INEOS parent a fuzzy search surfaces first.
  • Entities whose correct legal entity stays ambiguous are kept as unresolved leads, not pinned records (the leads: list — empty when all resolve). Prefer omission over a wrong match.
  • A direct/ultimate parent that returns 404 means GLEIF holds no reported relationship record — recorded as absent, which is not a claim that no parent exists (it may be an unreported reporting exception). GLEIF relationships are self-reported.

Files

  • lei-records.yamlmeta provenance + one record per pinned entity (LEI, legal name, jurisdiction, entity/registration status, legal address, reported direct/ultimate parent) + the unresolved leads.

Corridor relevance

  • General Dynamics Land Systems Inc. (875500ULXB4CYQSJVA03) reports its ultimate parent as General Dynamics Corporation (9C1X8XOOTYY2FNYTVH06) — an independent registry confirming the GDLS↔GD ownership behind the JSMC operator (the RSEI #3 Allen County facility and the defense-contractor scan).
  • Cenovus Energy Inc. (254900LJGL2N2XEMD470) is the post-2021 successor to Husky Energy, the RSEI Lima Refining Co parent.
  • The remaining watchlist entities are RSEI Allen County facility parents (Marathon, Ford, Dana, Textron, P&G, Shell) — the page cross-links the two datasets.
