QA Gate

Validate the assembled feature against the promises in its spec by exercising the public interfaces a real user reaches. The Daemon runs this skill from the unique authored terminal qa Task named by _tasks.md frontmatter; it is part of the Task Graph, not a per-run request. That node depends on every non-QA leaf and therefore becomes runnable only after the graph it closes settles. This skill owns the complete gate: plan, execution, evidence, findings, report, and final verdict. Use the agent's tools and connected servers directly; do not load another QA skill or create a separate living QA tree.
