PG impl dùng `tenantIDForInsert(ctx)` → nếu ctx không có tenant_id sẽ ghi vào tenant sai / nil. +- Tenant injection xảy ra **ở webhook handler**, không phải ở channel: `webhook.go:436` wrap `ctx := store.WithTenantID(context.WithoutCancel(req.Context()), portal.TenantID())` trước khi dispatch event. Ctx này propagates qua `DispatchEvent` → `handleMessage` → `provisionIfMissing` → `SetUserCredentials`, nên tenant luôn đúng với portal khớp `auth[domain]`. +- Test `8.3 #4` (SetUserCredentials insert thành công) + unit test riêng cho `tenantIDForInsert(ctx)` đảm bảo không leak. + +### 10.6 Token leak surface + +- OAuth tokens (access/refresh) lưu 2 chỗ: + 1.

Open questions + +1. **Phase D migration `"62.0" → "62"`**: bao nhiêu row bị ảnh hưởng trong D1 production? Cần query trước rồi script UPDATE một lần, hay đợi tự nhiên qua token refresh cycle? → đang nghiêng về script một lần vì idempotency không gặp vấn đề (bitrix_user_id là TEXT — `"62"` và `"62.0"` là 2 row khác nhau → user gửi lần kế tiếp sẽ tạo row mới, row cũ mồ côi). Cần schedule sớm. +2. **Phase E Open Channel shared creds**: một bot có thể gắn vào nhiều Open Channel queue khác nhau. 1 USR_ per bot đủ, hay cần 1 USR_ per (bot, queue)? Phụ thuộc use case — nếu permissions per queue khác nhau thì cần (bot, queue) key. +3. **Field encryption cho `users.access_token` trong D1**: hiện plaintext. Cloudflare D1 hỗ trợ at-rest encryption ở storage layer, nhưng không phải application-level. Nếu compliance yêu cầu → thêm field-level AES-GCM tương tự partner store của GoClaw. Chưa urgent — D1 access đã bị throttle qua Worker RBAC + Cloudflare account access. +4. **Webhook uninstall → revoke users**: khi admin uninstall MCP app khỏi portal, tenant row bị xoá, users của portal đó mồ côi. Hiện `users.tenant_id REFERENCES tenants(id)` **không có** `ON DELETE CASCADE` (verified trong schema.sql) — chỉ `idempotency_keys` có. Mitigation: (a) thêm CASCADE trên `users.tenant_id` + `api_keys.user_id` hoặc (b) hook webhook uninstall → explicit deactivate keys. (a) đơn giản hơn nhưng breaking với audit (xoá users = mất trace), (b) giữ row chỉ set `active=0`. +5. **`display_name` enrichment**: Bitrix webhook không carry `USER[NAME]` — GoClaw `contact_enrich.go` lazy `user.get` tại channel, nhưng MCP `createUser` không nhận display_name từ webhook → user rows có `display_name = NULL` trong MCP. Không critical (không ai hiển thị MCP user list ở UI hiện tại) nhưng nếu cần, GoClaw có thể forward `display_name` từ cache khi gọi `/api/auto-onboard`. +6. **Latency đo thực tế**: tin nhắn đầu của mỗi user onboard + verify = 2 Bitrix REST call (profile) + 1 D1 insert ≈ 300-600ms. Cache miss mỗi user chỉ 1 lần (lifetime). Nếu đo thấy spike khó chịu ở tin đầu → pre-warm khi bot được add vào chat (`handleJoin`), nhưng Bot Join event không có user_id của tất cả member → chỉ pre-warm được người add bot. Giữ lazy cho đơn giản. + +--- + +## 12. Changelog + +- **2026-04-23 (rev5)**: Path B shipped end-to-end. Bỏ ADMIN_TOKEN. + - MCP side: `/api/auto-onboard` rewrite dùng `verifyBitrixActive(profile)` làm auth anchor thay vì Bearer ADMIN_TOKEN. Thêm rate limit KV (600/min IP + 120/min domain), audit log `auto_onboard_audit`. Hourly re-verify trong `ensureFreshToken` để revoke USR_ của user bị dismiss khỏi Bitrix. + - GoClaw side: `mcpClient` bỏ `adminToken` field + Authorization header. `provisioner.go` bỏ `resolveMCPAdminToken` + 2 env consts (`GOCLAW_BITRIX_MCP_ADMIN_TOKEN`, `BITRIX_MCP_ADMIN_TOKEN`). `bitrixCreds` chuyển về empty struct. UI form drop `mcp_admin_token` field. (commit `07b48ef0`) + - Bỏ bảng mapping `bitrix_mcp_user_mapping` khỏi plan — reuse partner's `mcp_user_credentials` store. Tiết kiệm ~300 LOC: interface + 2 store impls + migration + SchemaVersion bump. + - Thêm user-facing degradation notice (`notifyUserOfMCPIssueOnce`) với 5-phút debounce per-user khi MCP fail ngoài sentinel. + - Status summary: MCP side ✅ deployed; GoClaw phase C ✅ landed (commit `ea09c1ba`); GoClaw ADMIN_TOKEN cleanup ✅ on local `dev` (commit `07b48ef0`, pending push). +- **2026-04-22 (rev4)**: MCP side implemented.
