- collector.symbols 与 supportedSymbols 加 SOL/BNB/DOGE,env-default 与 README 同步 - entity 追加 TechnicalStructure.Intervals(每周期 Bollinger + Vegas,omitempty 不破坏既有字段)与 DerivativesBundle.Signal - 新增纯解析 usecase derivatives_signal.go:fundingBias 绝对阈值、oiSignal 用 P20 baseline + 价格方向(OI up + 价格 up/down → long/short_building,funding 不参与方向)、lsrRegime 绝对阈值;signal 数据不足走 warnings 进 DataQuality - indicator.go 加 sma/stddev/ema/bollinger/vegas + computeIntervalTechnicals;IndicatorComputer 签名收 klines map - harness 同步:G12 扩入 derivatives_signal.go(含 Makefile G12.5/6 + ADR-0002 适用范围 + project-map / harness-health 更新)
