LIVE ENDPOINT METADATA

Reverse a 4-byte function selector, an event topic hash, or raw calldata into its human-readable signature using the 4byte database, with collisions resolved so the real signature (the oldest registered) is returned first and the attacker-registered lookalikes are flagged. Parameter types are parsed out.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
