Audit-ready iteration workflow for KV-cache eviction experiments: validate run artifacts (summary.json/logs.jsonl), classify result_type/claim_scope, enforce causal-claim gates, and automatically write/update labbook logs (MASTER_LOG.md, daily/YYYY-MM-DD.md, INDEX.md) with fixed schemas. Use when running or tuning KV eviction/compression experiments and needing reproducible, reviewer-grade logging + next-step patch plan.
