feat(迭代38卡④ 明细收敛批): 扩展行型收敛——四个专长实名行型（fx_reveal/mine_neutralized/insurance_used/fx_preview_area）收敛为单一 extended 行型＋effect_id 载荷（六发射点：orchestrator 三处＋grant_segment 三处，display_name/value/highlight 逐字不动）；a2 _emit_row 扩展行必载 effect_id 校验（emit 之前，违约 assert 炸零发射）；a3 fx_preview_area 来源类别空串违约修复（→fx_warning_beacon，对齐 fx_seal_smith 先例）；a4 头注换代两层词表（基础 9 类＋扩展行 1 类＋四效果身份发射点指引）；a5 呈现零改动核验（_format_row fallback 承载、AGG_TYPES 不含扩展行）；a6 裁点甲重锚（parity_anchor freeze 改后行为立新锚＋复闸三变体双面全同；改前对拍绿基线在案——stash 干净跑批实测）；验收=wr2 断言五条（insurance_used〔V6 扩展〕＋fx_reveal 兑付/落空〔真实揭示管线〕＋mine_neutralized/fx_preview_area〔treasure 套件首次 feats 注入〕）＋wr2-np 负面小套件（extended_row_violation_test，expect=1 negative，manifest 登记行）＋wr3 并⑤断言；撤销证明三条实测红绿复现；JSONL 读数对拍 PASS（type 迁移计数与 T0 基线对账 264/304/0/0，字段口径外零差异——type/effect_id/source_class/source 四字段，source=logger:133 同值改名副本）；改动面封闭（基础 9 类零触碰、豁免集合零变化、数值随机零变化）
