- gsc_signal_delta.py: extract `found` local var; add first branch in verdict_hint
chain so a term absent from both GSC windows yields INCONCLUSIVE (not ARTIFACT).
Existing ARTIFACT / CONFIRMED-PARTIAL / PARTIAL branches unchanged (elif chain).
- test_gsc_signal_delta.py: add test_absent_claim_term_inconclusive asserting
found=False and "INCONCLUSIVE" in verdict_hint for a term in neither fixture.
- code/CLAUDE.md: one-line surge-tuning note — verdict_hint/in_top_movers are
calibrated for upward claims; for drops, inspect top_decliners directly.

5 bite-sized tasks: SKILL.md measurement half (L1-L2) + decision half
(L3-L4/verdict), gsc_signal_delta.py helper with TDD tests, marketplace
registration + spec-layout reconcile, and a genesis-case smoke test that
asserts the JHR "호텔" claim resolves to ARTIFACT.

New conductor skill that adjudicates whether a claimed SERP/Knowledge-Graph
movement for a (term, entity) pair is real, misattributed, an artifact, or
unprovable. Stateless, on-demand; delegates measurement to seo-serp-analysis,
seo-position-tracking, and seo-knowledge-graph. Genesis: JHR "호텔 16→3"
SEMrush claim refuted via GSC/GA4/live-SERP cross-check.
