What

Prepare monitoring_system for a stable v1.0 release. Tier 3 library — depends on common_system, thread_system, and logger_system v1.0.

• Current version: 0.1.0
• Test coverage: 100% pass rate
• API stability: Medium

Part of kcenon/common_system#639

Why

• Provides monitoring/metrics infrastructure for higher-tier systems
• 100% test pass rate indicates solid foundation
• Must release after Tier 2 (logger_system) stabilizes

How

v1.0 Readiness Checklist

• API freeze audit: Review all public headers — no breaking changes after freeze
• Result<T> migration: Verify zero throw in public APIs
• CMake exports: Stable target name monitoring_system::monitoring_system
• Test coverage: Verify 70%+ unit test coverage (currently 100% pass rate)
• Deprecation cleanup: Remove any deprecated APIs
• Documentation: Complete API reference and migration guide from 0.x
• CHANGELOG: Ensure keep-a-changelog format
• Semantic versioning: Tag v1.0.0 release

Dependencies

• Blocked by: common_system v1.0 (Prepare common_system for v1.0 release common_system#640)
• Blocked by: thread_system v1.0 (Prepare thread_system for v1.0 release thread_system#670)
• Blocked by: logger_system v1.0 (Prepare logger_system for v1.0 release logger_system#604)

Acceptance Criteria

• All public API headers reviewed and frozen
• No throw statements in public API paths
• CMake find_package(monitoring_system) works cleanly
• Full test suite passes
• README documents v1.0 API guarantees
