Remove CLAUDE.md from version control

2026-02-17T11:37:27Z

Keep the file locally but gitignore it so project-specific Claude Code instructions are not pushed to the repository.

Add configurable log level as optional CLI argument

2026-02-17T10:57:52Z

All three programs now accept an optional second argument [log-level] (trace, debug, info, warning, error, fatal) defaulting to info. The level is applied by setting the logger context pointer directly, avoiding a memory leak that would occur from overwriting the heap-allocated logger struct. Also documents the ASan leak-check workflow in CLAUDE.md.

Replace CLI arguments with config-file parser and add integration tests

2026-02-17T10:07:37Z

Introduce a reusable key=value config parser (config.h/c) and convert all three programs to read their settings from config files instead of positional command-line arguments. Add example config files in config/ and 6 CTest integration tests covering None/Basic256Sha256/Aes128 with anonymous and user authentication. Remove the now-obsolete launch.sh.

Make authentication mode and credentials configurable via CLI

2026-02-17T02:31:40Z

Replace hardcoded user/password credentials with a new parameter that accepts "anonymous" or "user". When "user" is chosen, two additional arguments are required. ServerRegister accepts two independent auth modes: one for its own server-side access control and one for authenticating to the LDS when registering. ClientFindServers passes credentials to readServerTime, which selects UA_Client_connectUsername or UA_Client_connect accordingly. Update CLAUDE.md running examples and add an auth modes table.
