Crash-safe, race-free file writes for Go — TOCTOU protection via fingerprint verification, cross-platform file locking, atomic rename, and fsync for crash durability.
Audit logging for Azure/go-workflow — records every step execution event with timestamped events, export to JSON, NDJSON, diagrams, and an interactive HTML dashboard.
A Go library that wraps errors with context information (file, line, function) because debugging without context is like trying to find your dick in the dark.
Go wrapper for rpitx — subprocess-managed RF transmission via a singleton. Covers FM/RDS, Morse, POCSAG, FT8, SSTV, RTTY, FSK, IQ and more (12 modules). Dev-mode mocks execution so you can test without keying an actual transmitter.
