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)

edge 容器自带证书续期(certbot in nginx 镜像)
deploy-pangolin / deploy (push) Has been cancelled
- edge 改为自定义镜像:官方 nginx + certbot + dns-cloudflare 插件
- pangolin-entrypoint.sh:后台每12h certbot renew,续期后本容器内 nginx -s reload
- 不再需要宿主 cron / docker socket / 独立 certbot 服务做日常续期
- /etc/letsencrypt 改 rw 挂载,挂入 cloudflare.ini
- compose 去掉 build:(宿主 docker-compose 不支持 compose build),改脚本 docker build
- deploy.sh/cutover.sh: docker build -t pangolin-edge:local 后再 up

方案C:分发层容器化(edge nginx)+ Hy2 + DNS-01 续期
deploy-pangolin / deploy (push) Has been cancelled
- edge: 容器化 nginx 接管 80/443,逐字移植现网 vhost(blog/jiu/marzban/pay)+ stream SNI 分流
- singbox: Hysteria2(host 网络,UDP 443)
- certbot: DNS-01(Cloudflare)续期,容器化
- xray: REALITY 仅 profile newnode(本台沿用 Marzban)
- deploy.sh 幂等且切换感知;cutover.sh 一次性停宿主 nginx 切容器(可秒级回滚)
- 弃用方案A 的 host nginx-apply/sudoers/root-setup
- 部署目录改 ~/pangolin(免 root);CI 注入 CF_API_TOKEN
EC2 实测:edge nginx -t 通过(真实证书)、compose 校验通过
