Add repo-root .socket.json (critical=error, high=warn, medium/low=ignore)
and extend the evaluate-library skill's 8-filter protocol to 9 filters by
adding Filter 9 — Supply-chain behavior (Socket). Positions Socket last in
Phase 2 (most expensive: network call), documents socket-cli as the
verification command, and maps clean/flagged/<finding-summary> to the
trace's socketRisk field. Updates short-circuit skip lists for all earlier
Phase 2 filters and adds socketRisk to TRACE-TEMPLATE.md frontmatter.
Adds the /evaluate-library skill runbook at .claude/skills/evaluate-library/
with SKILL.md (8-filter + 3-prompt protocol, collect-cheap-skip-expensive
ordering, trace-write step, skip sentinel), POLICY.md (ADR-022 summary
≤2 pages), TRACE-TEMPLATE.md (complete YAML frontmatter + 11 headings in
order), and EXAMPLES/ with one approved (clsx) and one rejected
(trpc-to-openapi, named-consumer: fail) worked trace.
Updates session-start.sh to surface the skill in session pointers.
The skill is auto-registered by the harness on SKILL.md creation.
