-- 043 Schema 收敛（42 → 19 张表）：砍空转链路表、账号域清数据、同域合并、双迁移系统收尾。
-- 决策依据：docs/plans/2026-09-29-schema-consolidation-and-numeric-id.md
-- 账号域历史数据直接清空（账号即环境重构前置）；竞品采集数据无损保留。

-- 1) 空转链路表：任务发布链（content_draft/confirmation/operation_task/execution_attempt）、
--    自动运营链（creator_event/strategy/operation/conversation/message/cooldown/listener_*）、
--    素材链（creator_material_job）、双租约冗余（runtime_use_lease）、主小号关系（creator_relation）。
DROP TABLE IF EXISTS runtime_use_lease CASCADE;
DROP TABLE IF EXISTS creator_event_strategy_trace CASCADE;
DROP TABLE IF EXISTS creator_material_job CASCADE;
DROP TABLE IF EXISTS creator_cooldown CASCADE;
DROP TABLE IF EXISTS creator_listener_boundary CASCADE;
DROP TABLE IF EXISTS creator_listener_state CASCADE;
DROP TABLE IF EXISTS creator_message CASCADE;
DROP TABLE IF EXISTS creator_conversation CASCADE;
DROP TABLE IF EXISTS creator_operation CASCADE;
DROP TABLE IF EXISTS creator_event CASCADE;
DROP TABLE IF EXISTS creator_strategy CASCADE;
DROP TABLE IF EXISTS creator_relation CASCADE;
DROP TABLE IF EXISTS execution_attempt CASCADE;
DROP TABLE IF EXISTS operation_task CASCADE;
DROP TABLE IF EXISTS confirmation CASCADE;
DROP TABLE IF EXISTS content_draft CASCADE;

-- 2) audit_event 瘦身：任务/草稿/确认列与运行时实例列随链路删除。
ALTER TABLE audit_event
    DROP CONSTRAINT IF EXISTS audit_event_attempt_id_fkey,
    DROP CONSTRAINT IF EXISTS audit_event_confirmation_id_fkey,
    DROP CONSTRAINT IF EXISTS audit_event_task_id_fkey,
    DROP CONSTRAINT IF EXISTS audit_event_runtime_instance_id_fkey;
ALTER TABLE audit_event
    DROP COLUMN IF EXISTS confirmation_id,
    DROP COLUMN IF EXISTS confirmation_version,
    DROP COLUMN IF EXISTS attempt_id,
    DROP COLUMN IF EXISTS task_id,
    DROP COLUMN IF EXISTS runtime_instance_id;

-- 3) 账号域清数据：账号、凭据引用、环境、绑定、运行时实例全部清空重建；
--    CASCADE 链上的 creator_account_profile / creator_account_password / creator_account_metric
--    与 audit_event 一并清空。gateway / network_exit / 竞品采集数据不受影响。
TRUNCATE runtime_instance, environment_binding, browser_env, social_account, credential_reference
    RESTART IDENTITY CASCADE;

-- 4) environment_binding + runtime_instance 并入 browser_env（1:1 绑定 + 1:1 活跃实例）。
--    绑定列：account_id（UNIQUE，账号即环境）、network_exit_id（version 绑定代由 003 引入，复用）；
--    清理 fence 列：runtime_cleanup_*；活跃实例列：runtime_id/runtime_lease_until/runtime_network_id/runtime_node_id。
ALTER TABLE browser_env
    ADD COLUMN account_id text NOT NULL UNIQUE REFERENCES social_account(id) ON DELETE CASCADE,
    ADD COLUMN network_exit_id text REFERENCES network_exit(id),
    ADD COLUMN runtime_cleanup_pending boolean NOT NULL DEFAULT false,
    ADD COLUMN runtime_cleanup_binding_version bigint,
    ADD COLUMN runtime_cleanup_runtime_id text,
    ADD COLUMN runtime_cleanup_network_id text,
    ADD COLUMN runtime_id text,
    ADD COLUMN runtime_lease_until timestamptz,
    ADD COLUMN runtime_network_id text,
    ADD COLUMN runtime_node_id text,
    ADD COLUMN updated_at timestamptz NOT NULL DEFAULT now();
DROP TABLE runtime_instance;
DROP TABLE environment_binding;

-- 5) credential_reference 并入 social_account（provider + key 两列）。
ALTER TABLE social_account
    ADD COLUMN credential_provider text NOT NULL DEFAULT 'os_keyring'
        CHECK (credential_provider IN ('os_keyring', 'secret_manager')),
    ADD COLUMN credential_key text NOT NULL DEFAULT '';
ALTER TABLE social_account DROP COLUMN credential_reference_id;
DROP TABLE credential_reference;

-- 6) creator_work_source 并入 creator_work：work 已有 source_type/source_id 内联列，
--    来源表是双份状态；删除后来源切换仍由 upsert 覆盖内联列完成。
DROP TABLE creator_work_source;

-- 7) creator_metric_plan 并入 creator_work：调度列（发布/窗口/节奏/停点）并入作品行，
--    work 原有的 next_metric_at / metric_stop_reason 继续作为调度投影。
ALTER TABLE creator_work
    ADD COLUMN metric_plan_published_at timestamptz,
    ADD COLUMN metric_monitoring_end timestamptz,
    ADD COLUMN metric_plan_next_at timestamptz,
    ADD COLUMN metric_plan_interval_seconds bigint,
    ADD COLUMN metric_plan_multiplier double precision,
    ADD COLUMN metric_plan_max_interval_seconds bigint,
    ADD COLUMN metric_plan_point_index integer NOT NULL DEFAULT 0 CHECK (metric_plan_point_index >= 0),
    ADD COLUMN metric_plan_stopped boolean NOT NULL DEFAULT false;
UPDATE creator_work w SET
    metric_plan_published_at = p.published_at,
    metric_monitoring_end = p.monitoring_end,
    metric_plan_next_at = p.next_plan_at,
    metric_plan_interval_seconds = p.interval_seconds,
    metric_plan_multiplier = p.multiplier,
    metric_plan_max_interval_seconds = p.max_interval_seconds,
    metric_plan_point_index = p.point_index,
    metric_plan_stopped = p.stopped
FROM creator_metric_plan p WHERE p.work_id = w.id;
DROP TABLE creator_metric_plan;

-- 8) creator_source_sync_lease 并入 creator_collection_checkpoint（统一租约模式）：
--    账号/竞品同步互斥租约成为 checkpoint 的一种 collection_kind='sync'，与 works/comments 同写法。
ALTER TABLE creator_collection_checkpoint DROP CONSTRAINT creator_collection_checkpoint_collection_kind_check;
ALTER TABLE creator_collection_checkpoint
    ADD CONSTRAINT creator_collection_checkpoint_collection_kind_check
    CHECK (collection_kind IN ('works', 'comments', 'sync'));
INSERT INTO creator_collection_checkpoint
    (id, source_type, source_id, collection_kind, cursor, window_start, window_end, status, lease_token, lease_until, last_error)
SELECT 'sync:' || source_type || ':' || source_id, source_type, source_id, 'sync', '', now(), now(), 'idle', lease_token, lease_until, ''
FROM creator_source_sync_lease
ON CONFLICT (source_type, source_id, collection_kind) DO UPDATE SET
    lease_token = EXCLUDED.lease_token, lease_until = EXCLUDED.lease_until;
DROP TABLE creator_source_sync_lease;

-- 9) creator_settings 瘦身：转写配置列属于已砍素材链路。
ALTER TABLE creator_settings
    DROP COLUMN IF EXISTS transcription_provider,
    DROP COLUMN IF EXISTS transcription_model,
    DROP COLUMN IF EXISTS transcription_configured;

-- 10) 双迁移系统收尾：creator 域登记已折算进 schema_migration（038），登记表删除。
DROP TABLE IF EXISTS creator_schema_migration;
