wangjia 0fd3bce7a5 fix(server): 修复腐烂的集成测试套件 + devices 注册回填 last_seen 
这批 -tags integration 测试(usage/auth/codes/devices/store)因依赖冲突
长期编译不过、从未进 CI 跑过,代码静默腐烂。本次逐层修复:

- 依赖:testcontainers-go v0.34→v0.43(原 v0.34 配 docker v28.3.3 编译失败:
  archive.Compression/sockets.DialPipe undefined)。
- auth: LoginOutcome 重构成 Tokens 嵌套后,测试仍引用扁平 RefreshToken;
  users 测试 schema 缺 totp_enabled 列 → GetUserByEmail 报错 → SendCode 500。
- usage/auth/codes/devices: DSN 里 time_zone='+00:00' 作 URL query 透传时 '+'
  被解码成空格 → MySQL Error 1298 ' 00:00';改百分号编码。
- store: 测试 DSN 缺 multiStatements=true → 多语句迁移 Error 1064;
  WithConfigFile("") 在 v0.43 被拒,改写真 my.cnf 设 +08:00 真正考验 UTC 覆盖。
- devices(产品 bug):insertDeviceTx 把 last_seen 写进库却没回填返回值,
  刚注册的设备 API 响应 last_seen=null 与库不一致;TestFullChain 据此把关。

修复后完整 integration 套件 -p 1 串行全绿(25 包 + 5 testcontainers 包)。

wangjia 86b67c557b feat(server/db): 多库(3/4)— Dialect 抽象(upsert/锁)+ 合并 directory_version 
- db.Dialect:LockForUpdate(mysql "FOR UPDATE" / sqlite "")、Upsert(中性
  EXCLUDED.col → mysql VALUES()/ sqlite excluded.);DialectForDB 从连接驱动推导
- 9 处 ON DUPLICATE KEY、11 处 FOR UPDATE 全走 dialect;sqlite 靠 _txlock=
  immediate 取得 BEGIN IMMEDIATE 悲观锁等价语义
- directory_version 三处重复合并为 store.BumpDirectoryVersion(dialect 感知)
- 这些文件同时含(2/4)的 UTC→Go 改动(与 upsert/锁同语句交错,无法拆分)
- 顺带:usage 的 FIELD()、codes 的 DATE_ADD/GREATEST 续期、nodes 的
  UNIX_TIMESTAMP、NULLIF 等 MySQL 专属构造一并退回 Go/可移植写法

wangjia 20a1f8e2af merge: 管理端最小后台 + TOTP 双因素 [tsk_SCMtcGF4F434] 
以 main 现有 cmd/server 设计为准(保留 probe + /v1 路由),叠加分支新增:internal/admin/ 自包含后台(session/2FA/IP 白名单/审计/模板)、internal/totp/ + cmd/adminctl/(TOTP + 管理员创建 CLI)、cmd/server/main.go 的 startAdminIfConfigured()(opt-in:ADMIN_SECRET_KEY+DB_DSN 才起)。统一 getenvDefault 命名;go.mod 取 HEAD + go mod tidy(x/term 提为直接依赖);admins 迁移与 main 既有 000008_provision 撞号,重排为 000009_admins。

wangjia 6e99e32285 feat(admin): 管理端最小后台（独立监听 + 白名单 + 2FA）tsk_SCMtcGF4F434 
实现「一个二进制三个监听」中的管理端：

- 独立监听 ADMIN_LISTEN（默认 127.0.0.1:9443，FromEnv 拒绝 0.0.0.0/:: 等公网绑定）
- 中间件链：mw_ipallow（CIDR 白名单，仅信任 RemoteAddr，默认内网段）→
  mw_session（HttpOnly+Secure+SameSite=Strict cookie，Redis 30min 滑动 TTL）
- 登录双因素：argon2id 密码 + RFC6238 TOTP；失败限流与临时锁定；
  TOTP 密钥 AES-GCM 加密入库；migration 000008 增补 admins 表；
  首个管理员由 cmd/adminctl create 创建（终端输出 otpauth URI/Secret）
- 功能三块（html/template + embed 静态资源，原生 JS 二次确认）：
  1. 码批次：表单生成→明文仅在本次 CSV 下载出现（不落盘/不入日志）；
     批次列表 + 整批作废（复用 #3 codes，新增 Store.ListBatches/VoidBatch）
  2. 节点操作：列表 + 近期 node_events；replace 经 #14 ProvisionService、
     draining/up 经 #5 Lifecycle（二者未就绪→注入 stub，UI 置灰）；二次确认 + CSRF
  3. audit_log 查看：actor/action/target/时间范围过滤分页；同页查 node_events
- 所有写操作写 audit_log（actor=用户名，meta 不含明文）；管理端仅记安全事件
  （登录失败/锁定/白名单拦截），不记常规访问日志
- internal/totp 复用包（与 doc/05 用户中心 2FA 同算法，纯标准库）

测试：totp RFC6238 向量、argon2/AES 往返、白名单放行/拦截、会话滑动过期、
登录成功/密码错/TOTP 错/未知用户/锁定、批次 CSV 含明文且 audit 不泄露、
作废/节点操作的二次确认与 CSRF 缺失被拒、mock 断言 service 调用参数、审计过滤。

wangjia b64c002a33 feat(tsk_GXDoc3Cs07Rn): apierr + idgen + CONVENTIONS.md 
apierr:
- Add New() constructor, StatusFor() HTTP-status mapping
- Add ErrUnauthorized, ErrForbidden, ErrNotFound, ErrConflict predefined errors
- Add chi-compatible Middleware for panic(*Error) → JSON recovery
- Add apierr_test.go (8 tests; covers New, StatusFor, WriteJSON, Middleware)

idgen:
- Implement idgen.go: New()/NewString() (UUID v7 via google/uuid v1.6.0)
- Implement GenerateCode/CanonicalizeCode/HashCode (Crockford Base32 moved from codes)
- Add idgen_test.go (12 tests; UUID v7 ordering/uniqueness + Crockford format/normalization/check)

codes:
- Refactor generator.go to delegate GenerateCode/Canonicalize/Hash to idgen
- All existing codes generator tests continue to pass unchanged

server:
- Add CONVENTIONS.md covering package structure, error handling, ID generation,
  database conventions, handler templates, auth context, testing, and logging rules
- Move google/uuid from indirect to direct dependency in go.mod

wangjia 787151245e merge: maestro/tsk_tFMU7-hKzfOf [tsk_tFMU7-hKzfOf] codes 激活码模块 
解决与 1A 骨架的冲突：module 统一为 github.com/wangjia/pangolin/server
（codes 分支原用 pangolin/server，7 个源文件 import 已改写）；
go.mod require 并集(redis 取 9.20.1)；Makefile 以骨架为基底并入
build-codegen/test-unit/test-integration target。
go build/vet 通过，codes 单测通过。

wangjia afcd7b325c feat(codes): implement activation-code module (tsk_tFMU7-hKzfOf) 
Implements server/internal/codes/ with all required functionality:

## Generator (generator.go)
- Crockford Base32 16-char codes (15 data + 1 Crockford mod-37 check char)
- crypto/rand for unbiased random generation with rejection sampling
- Canonicalize(): I/L→1, O→0 folding, hyphen/space stripping
- Hash(): SHA-256 of canonical plaintext (only value stored in DB)
- Algorithm hard-coded; check char detects all single-char substitution errors

## Store (store.go)
- MySQL-backed via database/sql
- CreateBatch / CreateCode with ErrDuplicate on UNIQUE conflict
- FindCodeByHashForUpdate: SELECT … FOR UPDATE for row-level concurrency control
- MarkRedeemed, ExtendSubscription, CreateSubscription, GetActiveSubscriptions
- WriteAuditLog, CodeExistsByHash
- BeginTx at READ COMMITTED (FOR UPDATE provides row exclusivity)

## Service (service.go)
- Redeem(): 9-step flow with full idempotency and concurrency safety
  - isLocked / recordFail / clearFail via Redis key redeem:fail:{user_id}
  - SELECT … FOR UPDATE → single winner under N-concurrent redemptions
  - Same-plan: extends existing subscription (max(expires_at,now)+days)
  - Cross-plan: creates new subscription (max(now,latest)+days)
  - Idempotent: same user re-submits → 200 without re-applying
  - 5 failures → ACCOUNT_LOCKED for 1 hour (sliding window via Redis)
- CreateBatch(): generates N codes, stores hashes, returns plaintext once
  - Automatic retry on hash collision (birthday probability ≈10⁻⁸)

## Webhook (webhook.go)
- POST /webhook/store/codes — outside /v1, no JWT required
- HMAC-SHA256 with hmac.Equal constant-time comparison
- ±5 min timestamp window
- Redis SetNX nonce deduplication (15-min TTL)
- Idempotent: duplicate nonce → 200; duplicate code_hash → 200

## HTTP Handler (handler.go)
- POST /v1/redeem endpoint wired to Service.Redeem
- Reads userID from context key (set by JWT middleware from auth module)
- Bilingual error responses {code, message_zh, message_en}

## Export (export.go)
- ExportCSV(): streams plaintext codes to io.Writer as CSV
- Plaintext NEVER stored in DB; only SHA-256 hash persists

## CLI (cmd/codegen/main.go)
- codegen -plan -days -count -channel -note -dsn [-out]
- Transition tool until admin panel (#8) is ready
- Outputs CSV to stdout or file; warns operator about plaintext sensitivity

## Infrastructure (skeleton)
- internal/config/config.go: env-var configuration
- internal/db/db.go: MySQL connection pool helper
- internal/redisutil/redis.go: Redis client constructor
- internal/apierr/apierr.go: bilingual error types
- migrations/001_init.sql: DDL for codes module tables
- go.mod with all dependencies

## Tests
- generator_test.go (unit, no deps):
  - Format, uniqueness (10k codes, zero collisions), normalization,
    check-char detection of all single-char errors, hash consistency
- webhook_test.go (unit, no deps):
  - Signature rejection, missing signature, stale/future timestamp,
    missing nonce, constant-time HMAC comparison
- service_test.go (//go:build integration, testcontainers):
  - N=20 concurrent redeemers → exactly 1 winner
  - Idempotent redeem returns success for same user
  - Other-user redemption → CODE_REDEEMED + failure counted
  - 5 failures → ACCOUNT_LOCKED on 6th attempt
  - Same-plan extension: expires_at precision assertion
  - Cross-plan creation: new subscription row
  - Audit log written on every successful redemption
  - CSV export: no plaintext in DB, hash present
  - Webhook nonce replay: idempotent 200
  - Webhook same-hash: idempotent 200, single DB row

Run unit tests: make test
Run integration tests: make test-integration (requires Docker)
