+# Технический аудит EvoBGP
+
+## Executive summary
+
+EvoBGP — **hybrid control plane**: один процесс [`evobgp-all`](cmd/evobgp-all/main.go) (monolith) или **reference Compose** с разделёнными воркерами ([`docs/architecture.md`](docs/architecture.md)). Data plane (BIRD + agent) отделён от control plane (API + PostgreSQL + jobs).
+
+**Сильные стороны для нестабильной сети:**
+- Stale snapshot fallback по умолчанию (`EVOBGP_STALE_ON_UPSTREAM_ERROR=1`) — [`internal/pipeline/collect_stale.go`](internal/pipeline/collect_stale.go)
+- CDN/RIPEstat: retry (3×) + per-host circuit breaker — [`internal/httpclient/httpclient.go`](internal/httpclient/httpclient.go), [`circuit.go`](internal/httpclient/circuit.go)
+- ETag conditional GET, ASN TTL-кэш, parallel collect с cap
+- Подписанные бандлы Ed25519, verify перед apply
+
+**Главные риски для 10+ клиентов:**
+1. `jobs.Registry` — **in-memory, только в процессе API** (ARCH-04)
+2. DoH — **без retry/breaker** (критично при блокировках провайдеров)
+3. Один failed CDN source **без stale cache валит весь модуль**
+4. Production misconfiguration: `Bearer dev`, HTTP API, ephemeral bundle key
+5. Data race на `Job.Meta` и alias pointers в `store.Memory`

+
+| Профиль | Стиль | Когда |
+|---------|-------|-------|
+| `microvps` / `evobgp-all` | Monolith | 1 VPS, shared Registry |
+| reference Compose | Microservices-lite | API + scheduler/ingest/render/deploy |
+| Remote speakers | Edge agents | Panel→Node dispatch |
+
+### Узкие места (bottlenecks)
+
+| # | Bottleneck | Где | Impact |
+|---|------------|-----|--------|
+| B1 | **In-process job queue** | [`internal/jobs/job.go:175-177`](internal/jobs/job.go) | HA API невозможен без потери/дублирования jobs; scheduler без `EVOBGP_CONTROL_PLANE_URL` создаёт **отдельный Registry** — [`cmd/evobgp-scheduler/main.go:58-60`](cmd/evobgp-scheduler/main.go) |
+| B2 | **Module refresh = sync upstream fan-out** | [`internal/pipeline/collect_parallel.go`](internal/pipeline/collect_parallel.go) | До `EVOBGP_COLLECT_CONCURRENCY` (8 default, max 32) параллельных HTTP; worst case ~45s × retries на источник |
+| B3 | **Default job concurrency = 8** | [`internal/jobs/job.go:264-268`](internal/jobs/job.go) | При burst refresh 10+ tenants — очередь растёт, goroutine блокируются на sem |
+| B4 | **PostgreSQL pool default** | [`internal/db/open.go:28-38`](internal/db/open.go) | pgx default ~4 conns; при `JOB_MAX=16` + HTTP — contention без `EVOBGP_DB_MAX_CONNS=25` |
+| B5 | **Live endpoints fan-out** | [`internal/httpapi/peers_live.go`](internal/httpapi/peers_live.go) | N goroutines × N speakers, 12s timeout каждый |
+| B6 | **Broker — заглушка** | [`internal/broker`](internal/broker) | NATS URL логируется, очередь не распределена |
+
+### Масштабируемость
+
+- **Вертикальная:** хорошо до ~10–20 tenants при `evobgp-all` + tuning ([`docs/production-checklist.md`](docs/production-checklist.md))
+- **Горизонтальная API:** **не поддерживается** — два `evobgp-api` = два независимых Registry; `job_audit` в PG — audit only, не очередь исполнения
+- **Workers (ingest/render/deploy):** координируются через **общую БД**, не через jobs — OK для prefetch/drift
+
+### Отказоустойчивость
+
+| Сценарий | Поведение | Оценка |
+|----------|-----------|--------|
+| CDN/RIPEstat недоступен | Stale snapshot + circuit breaker | **Хорошо** (если был prior snapshot) |
+| DoH недоступен | Fail модуля или stale domain snapshot | **Средне** (нет HTTP retry) |
+| API restart mid-job | Job теряется из Registry; audit может быть inconsistent | **Плохо** |
+| PG недоступен | API `/v1/ready` → 503 | **OK** |
+| Agent unreachable | Deploy job succeed, drift в `evobgp-deploy` | **Частичный fail** (by design) |
+
+**Рекомендация:** для 10+ клиентов — **`evobgp-all` на каждом CP** или один CP + tuning; HA API требует **распределённой очереди** (NATS/Redis + worker pool) — задокументировано как future work.
+
+---
+
+## 2. Анализ кода
+
+### Антипаттерны
+
+| ID | Проблема | Файл | Критичность |
+|----|----------|------|-------------|
+| A1 | **Concurrent map read/write** — worker читает `j.Meta` без lock, handler пишет через `mergeMeta`/`Snapshot` | [`worker.go:108,263,379`](internal/jobs/worker.go), [`job.go:103-111`](internal/jobs/job.go) | **high** |
+| A2 | **Escape internal pointers** из Memory store | [`store/memory.go:416-475`](internal/store/memory.go) | **high** (tests/dev); **low** (prod PG) |
+| A3 | **Fire-and-forget goroutine** на каждый auth | [`auth.go:79-81`](internal/httpapi/auth.go) | **medium** |
+| A4 | **Silent error swallow** в prefetch | [`internal/ingest/run.go`](internal/ingest/run.go), `prefetch.go` | **medium** |
+| A5 | **Bypass resilience layer** — CDN preview прямой `Do` | [`routes_crud.go:267`](internal/httpapi/routes_crud.go) | **medium** |
+| A6 | **`EVOBGP_DEV_INSECURE` — dead code** | compose + [`server.go`](internal/httpapi/server.go) | **low** (misleading ops) |
+| A7 | **Unused Registry** в ingest/render/deploy binaries | [`cmd/evobgp-ingest/main.go`](cmd/evobgp-ingest/main.go) | **low** (resource waste) |
+
+### Maintainability
+
+**Плюсы:** чёткое разделение слоёв (ARCH-01..10), `store.Backend`, OpenAPI как контракт, engineering rules, table-driven tests в birdfmt/pipeline.
+
+**Минусы:**
+- Дублирование retry-логики (httpclient vs nodedispatch inline loop)
+- Env-tuning разбросан (`EVOBGP_*` в 15+ местах без central config struct для pipeline)
+- `Job` comment «персистенция в БД пока не подключена» устарел — hooks есть в [`bootstrap.go:67-92`](internal/httpapi/bootstrap.go)
+
+### Потенциальные баги и race conditions
+
+1. **`j.Meta` data race** — `-race` на `TestParallelModuleRefresh_*` + concurrent `GET /v1/jobs/{id}` polling
+2. **Memory store alias** — `deploy.Run` читает `LastAppliedRevisionID` пока worker пишет
+3. **peerLiveCache** возвращает slice без копии — [`peers_live.go:82-84`](internal/httpapi/peers_live.go)
+4. **TOCTOU idempotency** — terminal job удаляется из `byIdempo`, повторный POST создаст новый job (by design, но клиент должен знать)
+
+### Error handling
+
+**Хорошо:**
+- Префиксы ошибок (`httpclient:`, `birdfmt:`)
+- HTTP 5xx через `writeProblem`, без raw `err.Error()` (ERR-01)
+- `context.Context` в pipeline workers
+
+**Пробелы:**
+- `runRollback` без `workContext` — не отменяется — [`worker.go:500+`](internal/jobs/worker.go)
+- Prefetch/ingest: ошибки не логируются
+- `mergeBirdPostApplyMeta` — `context.Background()` 8s, игнорирует job cancel
+
+---
+
+## 3. Производительность
+
+### Блокирующие операции
+
+| Участок | Блокировка | Риск |
+|---------|------------|------|
+| `POST .../cdn-sources/preview` | Sync CDN fetch до 45s в HTTP handler | UI timeout, worker starvation |
+| `GET /v1/peers/live` | N × agent HTTP, wg.Wait | Slow при многих speakers |
+| Module refresh job | Sequential: ingest → render revision → optional deploy | Long job chain |
+| `bird -p` / `birdc configure` | Subprocess в deploy | Disk I/O на ноде |
+
+### Неэффективные алгоритмы / лишние запросы
+
+- **Tenant refresh:** `aggregateTenantPrefixRowsAll` — parallel по модулям, но каждый модуль может refetch все CDN/ASN/DoH — [`aggregate.go:28+`](internal/pipeline/aggregate.go). Snapshot skip есть через `module_hash` — проверять hit rate в meta.
+- **ASN resolve:** `PolitePause()` 150ms между AS — [`asnresolve/ripestat.go`](internal/asnresolve/ripestat.go) — при 50 AS = +7.5s minimum.
+- **GetModulePrefixSnapshot** вызывается многократно в одном refresh (cdn_snapshot, collect_parallel) — potential duplicate DB reads.
+- **Auth TouchAPIKeyLastUsed:** UPDATE на каждый request (async) — load на PG при high RPS.
+
+### Кэширование
+
+| Кэш | TTL | Gap |
+|-----|-----|-----|
+| ASN prefix cache | 1800s (`EVOBGP_ASN_CACHE_TTL_SEC`) | OK |
+| CDN ETag in DB | Until 304/change | OK |
+| Module prefix snapshot | Content-hash based skip | OK |
+| peerLiveCache | In-memory, per-process | Не shared между API replicas; нет defensive copy |
+| Circuit breaker state | Per-process | Не shared |
+
+### Конкретные улучшения
+
+```go
+// 1. CDN preview — использовать upstreamHTTPDo вместо прямого Do
+resp, err := pipeline.UpstreamHTTPDo(r.Context(), s.cdnHTTP, req) // extract upstreamHTTPDo
+
+// 2. Job.Meta — читать под lock или через Snapshot()
+st := j.Snapshot()
+mid, _ := st["meta"].(map[string]any)["module_id"].(string)
+
+// 3. Memory store — возвращать копии (как Postgres)
+modCopy := *mod
+return &modCopy, nil
+```

+## 4. Сетевое взаимодействие (критично)
+

+
+| Upstream | Timeout | Retry | Breaker | Stale fallback |
+|----------|---------|-------|---------|----------------|
+| CDN ingest | 45s | 3× linear | per-host | yes |
+| RIPEstat | 45s | 3× | per-host | yes + cache |
+| DoH | 10s/profile | **no** | **no** | domain snapshot |
+| CDN preview | 45s | **no** | **no** | N/A |
+| Scheduler→API | 45s | 3× | no | N/A |
+| Node dispatch | 30s | inline 3× | no | N/A |
+
+### Пробелы для блокировок провайдеров
+
+1. **DoH без retry** — transient timeout = fail; failover между profiles есть, но каждый profile — single shot
+2. **429/408 не ретраятся** — только `>= 500`
+3. **Нет jitter** — thundering herd при mass tenant refresh
+4. **DNS rebinding TOCTOU** — SSRF check до fetch, HTTP dial без pinned IP — [`cdn_url.go:75-115`](internal/pipeline/cdn_url.go)
+5. **Circuit breaker без half-open** — после 30s cooldown сразу full traffic — [`circuit.go:29-33`](internal/httpclient/circuit.go)
+6. **Breaker per-process** — ingest container ≠ API container
+
+### Рекомендации для нестабильной сети
+
+| # | Изменение | Effort | Effect |
+|---|-----------|--------|--------|
+| N1 | DoH через `DoWithRetry` + optional breaker | Low | **High** для DOMAINS modules |
+| N2 | Retry 429/503 с `Retry-After` + exponential backoff + jitter | Medium | **High** при rate limits |
+| N3 | **Partial CDN failure** — continue с stale per-source, не fail whole module | Medium | **High** |
+| N4 | Multiple DoH profiles + `failover` policy (already exists) — **документировать ops playbook** | Low | **High** (config, not code) |
+| N5 | Pinned dialer / custom `Transport.DialContext` после SSRF resolve | Medium | **Medium** (SSRF hardening) |
+| N6 | Proxy support (`HTTP_PROXY` / `EVOBGP_HTTP_PROXY`) для CDN/DoH | Medium | **High** в censored networks |
+| N7 | Unify CDN preview на `upstreamHTTPDo` | Low | **Medium** |
+
+---
+
+## 5. Устойчивость и надёжность
+
+### Graceful degradation
+
+**Работает:**
+- `EVOBGP_STALE_ON_UPSTREAM_ERROR=1` — ASN/CDN/domain stale — [`collect_stale.go`](internal/pipeline/collect_stale.go)
+- CDN 304 без local cache → forced full GET — [`cdn_snapshot.go:141-159`](internal/pipeline/cdn_snapshot.go)
+- DoH → system DNS fallback — [`doh_resolve.go:75-93`](internal/pipeline/doh_resolve.go)
+- Deploy: job succeed even if agent wake fails (drift detection)
+
+**Не работает / частично:**
+- Один CDN source fail без cache → **весь module_refresh failed** — [`collect_parallel.go:221-223`](internal/pipeline/collect_parallel.go)
+- Circuit open → immediate error, stale only if prior data exists
+- API shutdown: HTTP drain 15s, **jobs не cancel/drain** — [`cmd/evobgp-api/main.go:67-72`](cmd/evobgp-api/main.go)
+
+### Сценарии отказов
+
+| Событие | Что произойдёт |
+|---------|----------------|
+| **Потеря CP↔PG** | Ready=false; running jobs fail; no new jobs persist audit reliably |
+| **Потеря CP↔CDN** | Stale prefixes если были; иначе job fail; breaker opens 30s |
+| **Потеря CP↔agent** | Deploy meta `dispatch_failed`; BIRD на старой ревизии; drift logs |
+| **RIPEstat rate limit** | 429 → no retry → stale or fail |
+| **Рост нагрузки** | Job queue; goroutine pile-up; PG pool exhaustion; `/metrics` shows queue depth |
+| **API restart** | In-flight jobs lost; clients poll 404 or stale terminal state |
+
+---
+
+## 6. Безопасность
+
+| ID | Finding | Severity | Fix |
+|----|---------|----------|-----|
+| S1 | `Bearer dev` → operator при demo-seed | **high** (misconfig) | `EVOBGP_SEED_DEMO=0` — [`auth.go:66-92`](internal/httpapi/auth.go) |
+| S2 | API plain HTTP | **high** (ops) | TLS на edge (Traefik/nginx) |
+| S3 | Ephemeral bundle key без `EVOBGP_BUNDLE_SEED_HEX` | **high** (ops) | Stable seed + pubkey на нодах |
+| S4 | Compose defaults: weak PG password, `sslmode=disable` | **high** (ops) | Secrets manager, `sslmode=require` |
+| S5 | `/metrics` без auth | **medium** | Network policy / mTLS |
+| S6 | No rate limiting on auth | **medium** | Middleware limiter (e.g. per-IP) |
+| S7 | CDN SSRF DNS rebinding | **medium** | Pinned dialer after resolve |
+| S8 | `EVOBGP_CDN_ALLOW_PRIVATE=1` | **medium** | Never in prod |
+| S9 | `EVOBGP_NODE_DISPATCH_INSECURE_TLS=1` | **medium** | Valid TLS to agent |
+| S10 | Plaintext `EVOBGP_API_KEYS` in env | **medium** | DB keys via API |
+| S11 | `editor` can cancel jobs | **low** | Restrict to operator |
+| S12 | agent_secret `==` compare | **low** | `subtle.ConstantTimeCompare` |
+
+**SQL injection:** не обнаружено — параметризованные запросы в [`repository/`](internal/repository/).
+
+**Bundle crypto:** Ed25519 корректно; path traversal blocked в tar extract.

+
+## 7. Конкретные рекомендации (prioritized backlog)
+
+### High
+
+| # | Описание | Как исправить |
+|---|----------|---------------|
+| H1 | DoH без retry | Обернуть `hc.Do` в `DoWithRetry(ctx, hc, req, 3)` в [`refresh.go:288,360`](internal/pipeline/refresh.go) |
+| H2 | Data race `Job.Meta` | Читать через `Snapshot()` или добавить `MetaLocked()` accessor |
+| H3 | CDN source partial failure | В `collectCDNPrefixRows`: при err без stale — log warning + skip source вместо `return nil, r.err` (config flag `EVOBGP_CDN_PARTIAL_OK=1`) |
+| H4 | Production checklist enforcement | CI/deploy validation: reject `SEED_DEMO=1`, require `BUNDLE_SEED_HEX` |
+| H5 | Job queue HA roadmap | Persist queued jobs in PG + worker claim (`SELECT FOR UPDATE SKIP LOCKED`) или NATS — ARCH-04 |
+
+### Medium
+
+| # | Описание | Как исправить |
+|---|----------|---------------|
+| M1 | CDN preview bypass | [`routes_crud.go:267`](internal/httpapi/routes_crud.go) → `upstreamHTTPDo` |
+| M2 | Retry 429/503 | Extend `DoWithRetry` status check + parse `Retry-After` |
+| M3 | Graceful shutdown | On SIGTERM: `Registry.RequestCancelAll()` + wait workers with timeout |
+| M4 | Auth goroutine storm | Worker pool или sync touch with debounce |
+| M5 | HTTP proxy support | Custom Transport reading `EVOBGP_HTTP_PROXY` |
+| M6 | Memory store copies | Defensive copy in Get/List (dev/test safety) |
+| M7 | Rate limiting | `golang.org/x/time/rate` on auth middleware |
+
+### Low
+
+| # | Описание | Как исправить |
+|---|----------|---------------|
+| L1 | Jitter in backoff | `wait + rand.Intn(wait/2)` in DoWithRetry |
+| L2 | Half-open breaker | Single probe request after cooldown |
+| L3 | Remove dead `EVOBGP_DEV_INSECURE` from compose | Docs + compose cleanup |
+| L4 | Prefetch error logging | `log.Printf` or structured log in prefetch |
+| L5 | peerLiveCache defensive copy | `append([]T(nil), views...)` on store |
+
+---
+
+## 8. Quick wins (максимальный эффект / минимум усилий)
+
+1. **Ops (0 code):** [`docs/production-checklist.md`](docs/production-checklist.md) — `SEED_DEMO=0`, `BUNDLE_SEED_HEX`, `DB_MAX_CONNS=25`, `JOB_MAX=16`, `COLLECT_CONCURRENCY=16`, TLS edge, restrict metrics
+2. **DoH retry** — 5–10 строк в `refresh.go`, reuse existing `DoWithRetry`
+3. **CDN preview → upstreamHTTPDo** — 1 line change in handler
+4. **Job.Meta read fix** — replace 4 reads in `worker.go` with `Snapshot()` parsing
+5. **Log prefetch failures** — visibility без изменения behavior
+6. **Document DoH failover playbook** — multiple profiles (Cloudflare, Google, Quad9) + `failover` policy for censored regions
+7. **Run `go test -race ./internal/jobs/...`** in CI — catch Meta race
+8. **Prefer `evobgp-all`** over split reference for <20 tenants — eliminates Registry split bug

+## Итоговая оценка зрелости
+
+| Область | Оценка | Комментарий |
+|---------|--------|-------------|
+| Архитектура | 7/10 | Чистые слои; HA/API scaling — слабое место |
+| Сеть/resilience | 6/10 | CDN/ASN хорошо; DoH/preview — пробелы |
+| Concurrency | 6/10 | Registry продуман; Meta race, shutdown |
+| Performance | 7/10 | Parallel collect, caching; tuning needed at scale |
+| Security | 6/10 | Crypto OK; ops/config risks dominate |
+| Maintainability | 8/10 | Docs, rules, OpenAPI, tests |
+
+**Вердикт:** проект **готов для 10+ клиентов в single-CP deployment** (`evobgp-all` + PostgreSQL + production checklist) при условии ops discipline. Для **multi-CP HA** и **агрессивных сетевых блокировок** — приоритет: DoH retry, partial CDN failure, distributed job queue, HTTP proxy.

+---
+
+# Context7 — EvoBGP stack
+
+Перед `query-docs` открой `.cursor/rules/context7-stack.mdc` и выбери ID из таблицы по области задачи.
+
+## Workflow
+
+1. Определи область: `internal/` (Go), `web/` (Svelte), `docs/openapi.yaml`, `birdfmt`/`pipeline` (BIRD), `deploy/compose` (Docker).
+2. Найди строку в таблице `context7-stack.mdc`.
+3. Вызови `query-docs` с `libraryId` из таблицы и полным вопросом пользователя.
+4. `resolve-library-id` — только если библиотеки нет в таблице или нужна другая major-версия.
+
+## Быстрые ID (частые)
