UUID Generator V1

Purpose & User Intent: This tool generates UUID version 1 strings (time-based) in RFC 4122 format for unique identifiers used in logs, event streams, and distributed systems. Target users include backend developers, data engineers, and operations teams who need traceable IDs to correlate requests, transactions, and events across services. When a node value is supplied, the 48-bit node field uses that value; otherwise the generator derives a node from the system MAC address or falls back to a privacy-preserving random 48-bit value. The output is a canonical 36-character, lower-case string with the correct variant, version, and layout. Core Logic & Features: Required features include producing a valid UUID v1 with time_low, time_mid, time_hi_and_version, clock_seq, and node fields formatted as 8-4-4-4-12 hex. Outputs are single UUID strings with RFC 4122 conformance. Optional/advanced features: supply node and clock_seq inputs to influence the identifier; request multiple IDs in sequence; operate with MAC privacy options when hardware identifiers are unavailable; ensure the variant bits and version field follow RFC 4122; optimized for low latency and thread-safe generation suitable for high-throughput environments. The implementation is stateless, computing a new value per call without retaining user data between requests.
