+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `backend/`: Go service. `cmd/server` is the entrypoint, `internal/` contains handlers/services/repositories/server wiring, `ent/` holds Ent schemas and generated ORM code, `migrations/` stores DB migrations, and `internal/web/dist/` is the embedded frontend build output.
+- `frontend/`: Vue 3 + TypeScript app. Main folders are `src/api`, `src/components`, `src/views`, `src/stores`, `src/composables`, `src/utils`, and test files in `src/**/__tests__`.
+- `deploy/`: Docker and deployment assets (`docker-compose*.yml`, `.env.example`, `config.example.yaml`).
+- `openspec/`: Spec-driven change docs (`changes/<id>/{proposal,design,tasks}.md`).
+- `tools/`: Utility scripts (security/perf checks).
+
+## Build, Test, and Development Commands

+```
+
+## Coding Style & Naming Conventions
+- Go: format with `gofmt`; lint with `golangci-lint` (`backend/.golangci.yml`).
+- Respect layering: `internal/service` and `internal/handler` must not import `internal/repository`, `gorm`, or `redis` directly (enforced by depguard).
+- Frontend: Vue SFC + TypeScript, 2-space indentation, ESLint rules from `frontend/.eslintrc.cjs`.
+- Naming: components use `PascalCase.vue`, composables use `useXxx.ts`, Go tests use `*_test.go`, frontend tests use `*.spec.ts`.
+
+## Go & Frontend Development Standards
+- Control branch complexity: `if` nesting must not exceed 3 levels. Refactor with guard clauses, early returns, helper functions, or strategy maps when deeper logic appears.
+- JSON hot-path rule: for read-only/partial-field extraction, prefer `gjson` over full `encoding/json` struct unmarshal to reduce allocations and improve latency.
+- Exception rule: if full schema validation or typed writes are required, `encoding/json` is allowed, but PR must explain why `gjson` is not suitable.
+
+### Go Performance Rules
+- Optimization workflow rule: benchmark/profile first, then optimize. Use `go test -bench`, `go tool pprof`, and runtime diagnostics before changing hot-path code.
+- For hot functions, run escape analysis (`go build -gcflags=all='-m -m'`) and prioritize stack allocation where reasonable.
+- Every external I/O path must use `context.Context` with explicit timeout/cancel.
+- When creating derived contexts (`WithTimeout` / `WithDeadline`), always `defer cancel()` to release resources.
+- Preallocate slices/maps when size can be estimated (`make([]T, 0, n)`, `make(map[K]V, n)`).
+- Avoid unnecessary allocations in loops; reuse buffers and prefer `strings.Builder`/`bytes.Buffer`.
+- Prohibit N+1 query patterns; batch DB/Redis operations and verify indexes for new query paths.
+- For hot-path changes, include benchmark or latency comparison evidence (e.g., `go test -bench` before/after).
+- Keep goroutine growth bounded (worker pool/semaphore), and avoid unbounded fan-out.
+- Lock minimization rule: if a lock can be avoided, do not use a lock. Prefer ownership transfer (channel), sharding, immutable snapshots, copy-on-write, or atomic operations to reduce contention.
+- When locks are unavoidable, keep critical sections minimal, avoid nested locks, and document why lock-free alternatives are not feasible.
+- Follow `sync` guidance: prefer channels for higher-level synchronization; use low-level mutex primitives only where necessary.
+- Avoid reflection and `interface{}`-heavy conversions in hot paths; use typed structs/functions.
+- Use `sync.Pool` only when benchmark proves allocation reduction; remove if no measurable gain.
+- Avoid repeated `time.Now()`/`fmt.Sprintf` in tight loops; hoist or cache when possible.
+- For stable high-traffic binaries, maintain representative `default.pgo` profiles and keep `go build -pgo=auto` enabled.
+
+### Data Access & Cache Rules
+- Every new/changed SQL query must be checked with `EXPLAIN` (or `EXPLAIN ANALYZE` in staging) and include index rationale in PR.
+- Default to keyset pagination for large tables; avoid deep `OFFSET` scans on hot endpoints.
+- Query only required columns; prohibit broad `SELECT *` in latency-sensitive paths.
+- Keep transactions short; never perform external RPC/network calls inside DB transactions.
+- Connection pool must be explicitly tuned and observed via `DB.Stats` (`SetMaxOpenConns`, `SetMaxIdleConns`, `SetConnMaxIdleTime`, `SetConnMaxLifetime`).
+- Avoid overly small `MaxOpenConns` that can turn DB access into lock/semaphore bottlenecks.
+- Cache keys must be versioned (e.g., `user_usage:v2:{id}`) and TTL should include jitter to avoid thundering herd.
+- Use request coalescing (`singleflight` or equivalent) for high-concurrency cache miss paths.
+
+### Frontend Performance Rules
+- Route-level and heavy-module code splitting is required; lazy-load non-critical views/components.
+- API requests must support cancellation and deduplication; use debounce/throttle for search-like inputs.
+- Minimize unnecessary reactivity: avoid deep watch chains when computed/cache can solve it.
+- Prefer stable props and selective rendering controls (`v-once`, `v-memo`) for expensive subtrees when data is static or keyed.
+- Large data rendering must use pagination or virtualization (especially tables/lists >200 rows).
+- Move expensive CPU work off the main thread (Web Worker) or chunk tasks to avoid UI blocking.
+- Keep bundle growth controlled; avoid adding heavy dependencies without clear ROI and alternatives review.
+- Avoid expensive inline computations in templates; move to cached `computed` selectors.
+- Keep state normalized; avoid duplicated derived state across multiple stores/components.
+- Load charts/editors/export libraries on demand only (`dynamic import`) instead of app-entry import.
+- Core Web Vitals targets (p75): `LCP <= 2.5s`, `INP <= 200ms`, `CLS <= 0.1`.
+- Main-thread task budget: keep individual tasks below ~50ms; split long tasks and yield between chunks.
+- Enforce frontend budgets in CI (Lighthouse CI with `budget.json`) for critical routes.
+
+### Performance Budget & PR Evidence
+- Performance budget is mandatory for hot-path PRs: backend p95/p99 latency and CPU/memory must not regress by more than 5% versus baseline.
+- Frontend budget: new route-level JS should not increase by more than 30KB gzip without explicit approval.
+- For any gateway/protocol hot path, attach a reproducible benchmark command and results (input size, concurrency, before/after table).
+- Profiling evidence is required for major optimizations (`pprof`, flamegraph, browser performance trace, or bundle analyzer output).
+
+### Quality Gate
+- Any changed code must include new or updated unit tests.
+- Coverage must stay above 85% (global frontend threshold and no regressions for touched backend modules).
+- If any rule is intentionally violated, document reason, risk, and mitigation in the PR description.
+
+## Testing Guidelines
+- Backend suites: `go test -tags=unit ./...`, `go test -tags=integration ./...`, and e2e where relevant.
+- Frontend uses Vitest (`jsdom`); keep tests near modules (`__tests__`) or as `*.spec.ts`.
+- Enforce unit-test and coverage rules defined in `Quality Gate`.
+- Before opening a PR, run `make test` plus targeted tests for touched areas.
+
+## Commit & Pull Request Guidelines
+- Follow Conventional Commits: `feat(scope): ...`, `fix(scope): ...`, `chore(scope): ...`, `docs(scope): ...`.
+- PRs should include a clear summary, linked issue/spec, commands run for verification, and screenshots/GIFs for UI changes.
+- For behavior/API changes, add or update `openspec/changes/...` artifacts.
+- If dependencies change, commit `frontend/pnpm-lock.yaml` in the same PR.
+
+## Security & Configuration Tips
+- Use `deploy/.env.example` and `deploy/config.example.yaml` as templates; do not commit real credentials.
+- Set stable `JWT_SECRET`, `TOTP_ENCRYPTION_KEY`, and strong database passwords outside local dev.

+
+如需启用管理后台“数据管理”，需要额外部署宿主机数据管理进程 `datamanagementd`。
+
+关键点：
+
+- 主进程固定探测：`/tmp/sub2api-datamanagement.sock`
+- 只有该 Socket 可连通时，数据管理功能才会开启
