Context

Part of kcenon/common_system#685 (Wave 1, P0). Tests reference: container_system.

Problem

• prior audit of tests/CI relied on inference (tool I/O failure) -> needs direct re-verification
• no dedicated fuzz/ target (structured/encrypted writer, otlp parser)

Acceptance Criteria

• tests/*.cpp assertion density and .github/workflows/* matrix verified and documented
• dedicated fuzz/ harness + weekly fuzzing workflow

Notes

Weekly fuzzing workflow touches .github/workflows/ -> requires workflow token scope.

Derived from the 2026-05-30 multi-agent cross-system level-matching analysis (workflow wf_0a968699-e07). Reference systems: documentation=common_system, code-structure=monitoring_system, tests/examples=container_system.
