about

nx_source_tier.nx -- the research-established ranking rule, bits-up. module: nishi-core.search.bench.source_tier depends: fx.nx (Q16.16 tier scores), nx_str.nx (substring matching) capability: CORE_COMPUTE wired_status: FULLY_WIRED Operationalizes the operator's principle: FIRST-HAND source material (the actual film / official photo / canonical record / direct interview) ranks ABOVE derivative commentary (reaction videos, "top 10" listicles, SEO aggregators, tier-lists). This is the anti-Google ranking thesis from docs/00-VISION + the five-tier taxonomy from docs/04-DEDUP. Two-stage, data-driven (Rule #11 -- the tables ARE the policy): 1. domain -> base tier (primary/editorial/platform/archive/community) 2. title/url "derivative" signals DEMOTE a result to commentary even on a high-tier domain (a YouTube reaction video is platform AND derivative; the same channel's official trailer is not). A result is_primary (first-hand) iff base tier == PRIMARY and no derivative signal fired. That boolean feeds nx_bench_primary_precision_at_k; the gain (tier score, zeroed when derivative) feeds nx_bench_dcg/ndcg. Tier scores from docs/04-DEDUP: primary 1.0, editorial 0.9, platform 0.7, archive 0.6, community 0.5, unknown 0.3 (Q16.16).
