    Tier D · a leaderboard, listed apart

    D

    Long tail: little or no usage data yet.

    How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

    How we got to tier D
    1. Adoption: no usage data. Tier D.
    2. Not yet read on X.
    3. In curated RL directories: 1 point, a floor of none.
    4. Confirmed: a line from its own site or paper places it.
    5. Judged a leaderboard, arena or index rather than one benchmark (or not a benchmark at all): listed apart.

    A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
