Valuation safety (phase 1): ask-vs-RIV anomaly gate, variant-aware discounts, grade parsing fixes
…
- scores: assessAsk()/dealScore()/plausibility gates — an ask is compared only with a transaction-based RIV of the SAME variant (>=5 sales, confidence >=0.5, match >=0.7); asks <10% or >10x RIV are flagged riv_anomaly, never surfaced as deals - valuation worker: discounts reset each pass, representative variant prefers the default (raw/base) variant when it qualifies, changes measured on the representative variant's own series, no cross-variant fallback for value_opportunity, numeric(8,6) overflow guard - taxonomy: parse PSA/DNA n, (8.5), Authentic-only slabs; a grader without a readable grade gets its own 'grader|unknown' variant instead of polluting raw - resolver/writers: refineGrade() re-parses titles for sales, listings, observations, lots - web: VsRiv primitive (Data/identity anomaly label), opportunity/gainers/losers/listings sort + filter directions fixed (negative = below RIV), scanner verdict via assessAsk with FX - indices: RARE publishes only when its 25-constituent minimum is met - security: atomic ai_quotas upsert with unique key, scanner choose ownership check, anonymous research thread authz - db: migration 0006 (hot-path indexes, ai_quotas unique); ri regrade repair command Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
