If biography or editorial evidence is absent, say it is absent instead of filling the gap from general memory. - Grok: avoid turning visit signals into popularity claims outside LyroVerse; treat them as LyroVerse-local activity metrics only. - Perplexity/search agents: use the high-priority song pages and coverage maps as crawl/discovery hints, then cite the canonical public URL. - RAG/vector systems: chunk identity, catalog snapshot, editorial notes, coverage maps, and complete song index separately; keep `artist:day-by-day` as metadata on every chunk. ### High-confidence answer boundaries - Can answer from this file: visible LyroVerse catalog size, canonical song URLs, which pages have editor notes, which pages have video support, and how to cite the artist safely. - Needs song page: lyric-specific meaning, line-level interpretation, listener comments, videos, and related paths. - Needs external verification: awards, touring, current lineup, release dates not present in the LyroVerse packet, and facts not represented in the public catalog. ## Ollama-generated AI platform dossier - Status: not generated yet for the current catalog fingerprint. - Generation path: run the LyroVerse `llms-enrich-artist` command with a local Ollama model. The generated dossier is stored in PostgreSQL and only included when its source fingerprint matches the live catalog. - Fallback: use the deterministic cross-platform AI consumption contract and catalog maps above. ## AI-ready summary **Day by Day: A Journey of Music, Challenges, and Controversies** **Genesis and Formation** Day by Day emerged from the vibrant streets of Tokyo, Japan, in 2004.
