Public brief / source-backed packet

Fixed broadband: HHI briefing

Orient readers to observed changes, evidence custody, and the questions that still require investigation. This packet keeps 1 latest-to-prior observation across 1 evidence system separate and does not rank or combine them.

The latest encoded HHI anchor is higher within this documented market series. The change alone does not identify a cause or establish competitive harm.

Research questionWhich entry, exit, share, switching, price, quality, or capacity evidence can explain the movement inside this exact market boundary?
Interpretation boundary

Every signal compares declared observed anchors inside the same series or cross-section. Missing years are not interpolated, intervals are not annualized, and market, industry, geographic, business-flow, and merger measures keep separate units, universes, period bases, and legal meanings. Antitrust Radar does not combine them into a composite competition score.

Publication standard

A briefing is a research handoff, not a finding of liability.

Every exported packet carries the observed comparison, source register, bounded interpretation, next research question, and the global no-composite-score rule.

  1. 01
    State what changed

    Report the exact prior and latest anchors with their period basis and interval.

  2. 02
    Keep systems separate

    Do not compare the magnitude of unlike HHI, share, business-flow, transaction, and review-rate changes.

  3. 03
    Open the investigation

    Route each signal into its underlying profile, explorer, source records, and research question.

The studio packages current observations; profiles, explorers, reports, and public data remain the authoritative analytical surfaces.
