Recovered: 61 · became unreachable: 32 · new packages: 243 · removed packages: 4 · package version changes: 461.

What this does not prove

  • The score measures agent-readiness metadata, schemas, discovery and declared safety cues — not correctness or security.
  • Unreachable means the package could not be graded fairly; it is not a low score.
  • A score movement is directional evidence only when both runs use the same engine version and the package version is unchanged.
