What changed,
and when.

Only material editorial, coverage, and data-contract changes belong here. Automated builds and link checks do not create releases.

    Initial Energy Field Atlas edition

    BTU Graph became a broad, evidence-backed energy company directory with an open public data layer.

    • Published 50 company profiles across 12 energy sectors, spanning operators, field services, infrastructure, LNG, refining, power, engineering, trading, data, AI, and software.
    • Attached at least two public evidence records to every company profile and separated company-stated facts from BTU Graph editorial classification.
    • Released graph JSON schema v3, a normalized company CSV, an OpenAPI contract, RSS updates, and concise and expanded agent guides.
    • Added a disclosed Oil Price API market-context module and an explicit company-page placement allowlist independent of directory inclusion or rank.
    • Separated first-published, materially-updated, and evidence-review dates so routine checks do not create false freshness signals.
