concentration
0.840 traffic splits near-evenly across many unrelated stacks.
category
Looks like an auth endpoint — a hostname heuristic, high-precision / low-recall, not a verdict.
synthesis
Many unrelated stacks reaching an auth endpoint in near-equal proportion is the credential-stuffing shape. The corpus records no per-connection identity and cannot confirm intent.
Spread is entropy over the fingerprints reaching this domain, not over the domains a fingerprint reaches. It can’t distinguish one scraper from many people — it measures the mix of software, not who runs it.
