ClawSecCheck (genuine install — self-excluded by CONTENT)
The control case for own-name self-exclusion. This directory carries the real
package layout: a checks/ package whose sources contain the distinctive engine
symbols (def check_installed_skills, def vet_skill, _SKILL_CRIT).
A security auditor necessarily ships attack signatures and red-team payloads as
data, so checks/_engine.py below embeds exactly the kind of string the audit
hunts for. If self-exclusion ever regressed to name-only — or stopped working at
all — those signatures would self-flag and this fixture would start reporting
findings. It must report none.
