feat(agent): node agent — enroll/mTLS, heartbeat, command stream, sing-box 用户表 (tsk__R8M4jEw43JR)
...
与控制面同仓同 go.mod，新增节点 agent 实现：
- proto/agent/v1/agent.proto + internal/pb/agentv1：冻结的控制面↔agent gRPC 契约
（Enroll/Register/Heartbeat/Subscribe/Ack/ReportUsage）。仓库尚无 protoc 流水线，
暂以手写 Go 类型 + JSON gRPC codec 实现，与 proto 1:1 对应，待 protoc 接入即可替换。
- internal/agentd：
- enroll.go：首启生成 EC 密钥+CSR，持 bootstrap token 调 Enroll 换 90d 节点证书
（CN=node_uuid），落 /etc/pangolin-agent/，此后 mTLS。
- conn.go(agent.go)+creds.go：mTLS 主动拨号 + 指数退避重连；重连携带 last_command_id；
Register 取 ConfigSnapshot 全量配置覆盖本地。
- heartbeat.go：30s 上报 peer/带宽/CPU + config_version；need_full_resync→全量同步。
- command.go：消费 Subscribe，Upsert/Revoke/Rotate/ApplyConfig/Lifecycle 幂等处理后
Ack（at-least-once，按 command_id 去重）。
- singbox.go+render.go：内存用户表 + 落盘 state.json（仅 dp_uuid+expires_at）；任何变更
渲染完整 sing-box 配置（REALITY users[uuid,flow] + Hy2 users[派生口令]）→ 500ms 去抖
合并 → systemd 重启。
- ttl.go：凭证 TTL 定时移除并上报。
- usage.go：按 dp_uuid 聚合上报，绝无 user_id/email/目的地址。
- derive.go：Hy2 口令 = HMAC-SHA256(key, dp_uuid)，与控制面同源派生。
- cmd/agent：入口（flag/env 配置）。
- infra/cloud-init/{node.yaml.tmpl,install-node.sh,README.md}：一段式安装，下载锁定版本
二进制并校验 SHA-256，systemd 拉管，首启即 Enroll/Register。shellcheck -S warning 通过。
测试（bufconn mock 控制面，无需 docker）：Enroll→Register→Heartbeat 全流转；Upsert/Revoke
渲染正确；Rotate 宽限期新旧并存到点移除；TTL 自动移除并上报；断流重连 last_command_id
续发不丢不重；need_full_resync 触发重注册；state.json 恢复；去抖合并；扫描确认无身份字段。
go test -race ./internal/agentd/... ./internal/pb/... 通过；go vet ./... 通过。
落实 doc/04 §2 节点无状态化与 doc/06 §3 数据面红线（节点仅见 dp_uuid）。

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

feat(mtls): implement mTLS/CA + bootstrap token framework [tsk_FUQws_DMIcXa]
...
ECDSA P-256 self-signed CA with disk persistence (load-or-generate),
CSR signing (CN=nodeUUID, 90d validity, EKU=ClientAuth), one-time
bootstrap tokens via Redis GETDEL (15min TTL), CRL revocation with
Redis SET + DB interface, gRPC unary+stream interceptors that extract
CN from verified TLS chains (Enroll whitelisted, others require cert),
and NewServerTLSConfig (VerifyClientCertIfGiven + TLS 1.3 + CRL hook).
Frozen API: SignCSR / CAPEM / IssueToken / ConsumeToken / Revoke /
NewServerTLSConfig / UnaryServerInterceptor / NodeUUIDFromContext
Tests cover: CA sign+verify, token one-time guarantee, TTL expiry,
revocation rejection, interceptor whitelist (5 categories).
Redis layer backed by miniredis in tests.
Run setup.sh from server/ to fetch deps and verify tests pass.
