%description
TaskHealth is a client-daemon thread health monitor for Linux user-space,
inspired by QNX HAM. The daemon (taskhealthd) accepts registrations from
multiple processes via Unix domain socket and performs cross-process
heartbeat monitoring, /proc probes, and alerting.

Detects unexpected thread exits, futex deadlocks, and lock-wait timeouts.

%description -n taskhealthd
The taskhealthd daemon — Unix domain socket server that monitors registered
threads across processes. Runs the watchdog detection engine and outputs
alerts to stderr, syslog, a log file, or an external script.

Summary:  TaskHealth client shared library

%description -n libtaskhealth
Client library linked into business processes. Communicates with taskhealthd
