hoelee 4693c9d684 feat(W4): daily full reconciliation — user/role drift repair + ReconcileLogs audit
- w4-body.js: ONE-DIRECTIONAL sync (NocoDB status = SOT, never reverse);
  drift matrix: missing user/role (provision w/ username lookup to avoid
  duplicates), dangling refs (adopt/recreate), disabled<->status, canonical
  base_path '/' + permission 16384, scopes vs calculateEffectiveGrants,
  username drift detect+log_only; verify-after-repair on every change;
  password never pushed on repair (方案 C); dry-run via ?dryRun=true
- gen_w4.js: daily 03:00 cron + webhook alist-w4-reconcile; API-import-safe
  (UUID node ids, no pinData, webhookId)
- ReconcileLogs table mktsb7le6fqr2u1 (add_reconcilelogs_table.py, idempotent,
  v2 API); FK column nc_jitu___Customers_id for bt-link writes (v2 ignores
  link column itself)
- test_w4_reconcile.js: 34 assertions / 12 mock worlds, ALL PASSED
- live-verified against production: dry-run (3 drifts + 1 error found),
  real repair (3 repaired, verify all passed, 4 log rows), idempotent rerun
- NocoDB 2026.08.x pitfalls documented (v1 col endpoints gone, row delete
  via body [{Id}]); n8n API import/activation pitfalls (activeVersionId)
- docs: W4-DESIGN.md new; DATABASE_SCHEMA 8 tables; N8N_WORKFLOWS, SETUP,
  PROJECT_STATE updated

n8n Workflow 说明(已实施)

n8n 运行在现有 auto.hoelee.com(bridge_hoelee 网络)。它是同步器,不是 SOT。 更新日期 2026-08-23。

已实现的三个 Workflow

Workflow ID 触发 职责
W1 Customer Provision & Status Lifecycle gU2ee9Eg5w1KzB5p NocoDB Customers webhook provision + 整户 status lifecycle
W2 CustomerProduct Sync D9OWAI7JUjKnRdOn NocoDB CustomerProducts webhook 重算该客有效 grants 并应用
W3 Expiry Sync zlEfjj5eK5IfILtk schedule */5 定时
W4 Daily Full Reconciliation pl8j9lpg5gjrd0dB 每日 03:00 + webhook alist-w4-reconcile 全量对账 + 用户/角色级 drift 修复 + ReconcileLogs

三个 workflow 共享同一套算法 calculateEffectiveGrants(n8n/shared/effective-grants.js, 构建时经 gen_w1/w2/w3.js 内联进各 Code 节点)。

W1 — Customer Provision & Status Lifecycle

  • 触发:Customers 表 after-insert / after-update(webhook alist-customer-provision)
  • 单一 Code 节点,处理 5 状态:
    • active(无 user)→ 建 role + 建 user + 重算 grants + enable
    • active(有 user)→ re-enable + 重算 grants(不恢复旧值)+ 应用
    • pending/suspended/expired/deleted(有 user)→ disable + 清空 scopes
    • pending/suspended/expired/deleted(无 user)→ no-op
  • 回填 alist_user_id / alist_role_id,写 sync_status=synced

W2 — CustomerProduct Sync

  • 触发:CustomerProducts 表 after-insert / after-update(webhook alist-customerproduct-sync)
  • 读 CP → 定位 customer → 重算该客 grants → diff AList role → 有变化才 role/update 整体重写
  • customer link 为空时优雅跳过(不回写)

W3 — Expiry Sync(全量对账)

  • 触发:每 5 分钟 schedule
  • 逐客调 calculateEffectiveGrants → diff → 应用
  • Env 开关:W3_DRY_RUN=true(只打印计划)、ALIST_AUTO_DISABLE_ON_EXPIRE=true(scopes 变空时 disable 用户)

W4 — Daily Full Reconciliation(每日全量对账)

  • 触发:每日 03:00 cron + 手动 webhook(/webhook/alist-w4-reconcile,?dryRun=true 出计划)
  • 单向同步:NocoDB status 是 SOT,W4 只修 AList,永不反向改 NocoDB status
  • 覆盖 W3 不管的 drift:缺 user/role → 按 username 反查防重再 provision;悬空引用 → adopt/recreate; 非 active → disable + 清 scopes;base_path/permission 修回 canonical(/ + 16384); username drift → detect + log_only;修复后逐个 verify 回读,失败记 verify_failed
  • 写 ReconcileLogs(表 mktsb7le6fqr2u1),只记 drift/repair/error 行;customer 链接用 FK 列
  • 密码随 repair 不推送(方案 C)
  • 详见 docs/W4-DESIGN.md

共用 env 变量

n8n Code 节点内用 $env.VAR(process.env 不可靠)。下表是本项目需要的 env:

变量 说明
NOCODB_URL / NOCODB_TOKEN NocoDB 地址 + xc-token
NOCODB_TABLE_CUSTOMERS / ..._CUSTOMERPRODUCTS / ..._PRODUCTS / ..._RESOURCES / ..._ACCESSGRANTS / ..._RECONCILELOGS 各表 model_id(ReconcileLogs = mktsb7le6fqr2u1)
NOCODB_FK_RECONCILELOG_CUSTOMER ReconcileLogs.customer 的 FK 列名 nc_jitu___Customers_id(W4 写链接必须用 FK 列)
NOCODB_LINK_PROD_RESOURCES Product↔Resource M2M 列 id(c4ko4x8kwi16swg)
ALIST_URL http://alist-serve-resource:5244(n8n 容器内)
ALIST_ADMIN_USERNAME / ALIST_ADMIN_PASSWORD AList admin 登录
W3_DRY_RUN / ALIST_AUTO_DISABLE_ON_EXPIRE W3 开关

幂等规则

所有操作 = get current → compare → apply diff。重跑不产生重复 user/role/scope。 更新 scope 一律「整体重写该 role 的 permission_scopes」。

Loop 防护(重要)

  • n8n 只写回 bookkeeping 字段(alist_user_id/alist_role_id/sync_status/sync_required/last_sync/last_sync_error)。
  • W1 用 old/new field comparison(NocoDB previous_rows vs rows)区分「业务变更」vs「echo」;echo 直接短路。
  • writeBack() 值比对守卫:字段值不变就不发 PATCH,掐断 echo loop。

依赖的 AList API(源码级验证,见 API_INTEGRATION.md)

  • 登录:POST /api/auth/login
  • User:/api/admin/user/{list,get,create,update,delete}
  • Role:/api/admin/role/{list,get,create,update,delete}(delete 用 ?id= query param)
