-- T003: 扩展功法系统 - 新增神通/秘术功法类型
-- 对齐GDD-04 v1.12 新增决策✅22-✅26

-- 1. 扩展manuals表的category字段值（原有universal/profession/racial/unique）
-- 新增：divine（神通）、forbidden（秘术）

-- 2. 创建功法类型配置表
CREATE TABLE IF NOT EXISTS manual_types (
    id              VARCHAR(32) PRIMARY KEY,
    name            VARCHAR(64) NOT NULL,
    description     TEXT,
    max_equipped     SMALLINT NOT NULL DEFAULT 0, -- 0=不限（自然约束）
    acquisition_req JSONB NOT NULL DEFAULT '{}',  -- 获取条件
    usage_cost      JSONB NOT NULL DEFAULT '{}',  -- 使用代价
    cooldown_config JSONB NOT NULL DEFAULT '{}',  -- 冷却配置
    conflict_rules  JSONB NOT NULL DEFAULT '[]',  -- 冲突规则
    created_at      TIMESTAMPTZ DEFAULT NOW()
);

-- 3. 插入功法类型数据
INSERT INTO manual_types (id, name, description, max_equipped, acquisition_req, usage_cost, cooldown_config, conflict_rules) VALUES
-- 基础功法类型
('heart_method', '主修心法', '决定内力积累效率、内力上限、内力纯度基线', 0, '{}', '{}', '{}', '[]'),
('combat_skill', '战技功法', '修炼后解锁战斗招式（普攻强化/主动技/被动）', 0, '{}', '{}', '{}', '[]'),
('auxiliary', '辅助功法', '提供修炼/游历/纯化等增益', 0, '{}', '{}', '{}', '[]'),
('production', '生产联动功法', '与生活技能联动', 0, '{}', '{}', '{}', '[]'),
-- 新增功法类型（T002审阅）
('divine_power', '神通功法', '修炼到高境界后领悟的超凡能力，威力远超普通战技', 0,
 '{"min_realm":4,"min_manual_layer":7,"require_epiphany":true}',
 '{"energy_cost":"high","special_resource":"精血/寿元","battle_cooldown":"24-72h"}',
 '{"battle_cooldown_hours":48}',
 '[]'),
('forbidden_art', '秘术功法', '禁忌之术，代价高昂但威力极大', 0,
 '{"min_realm":5,"require_special_bloodline":true,"require_special_item":true}',
 '{"energy_cost":"extreme","karma_cost":"10-50业力","lifespan_cost":"数年寿元"}',
 '{"battle_cooldown_hours":168}',
 '[]');

-- 4. 扩展manuals表的category约束
