HarnessFlow v3.0.0: 7 core skills own the risk-tiered main chain frame -> plan -> build -> verify -> ship (hf-workflow entry, hf-frame with environment baseline, hf-plan, hf-build TDD, hf-verify runtime smoke, hf-review with independent-context discipline, hf-ship). A stdlib-only mechanical gate (skills/hf-workflow/scripts/hf_gate.py) produces tamper-evident evidence logs and adjudicates every stage transition from files, verdict lines, exit codes and timestamps. Domain skills plug in as ext-* extensions loaded per stage (ext-ui-design and ext-cpp ship as seeds).
