fix(ci): restore changed-path detection on multi-commit pushes

Push-чекаут в quality-воркфлоу делался с fetch-depth: 2, поэтому
BEFORE_SHA (github.event.before) при пуше нескольких коммитов
отсутствовал в чекауте, и git diff падал с "fatal: bad object"
(exit 128). Чекаут переведён на fetch-depth: 0; перед диффом
добавлен guard git cat-file -e: если before недоступен
(force-push), шаг не падает, а уходит в полный прогон через
empty-diff fallback.

 Профиль Compose **`microvps-full`** добавляет к этому стеку **Web UI** (nginx → `evobgp-all`), **NATS** и **Prometheus** без отдельных контейнеров воркеров (функционально то же, что отдельные `scheduler`/`ingest`/… в reference). Запуск и лимиты под ~1 ГиБ RAM — в [quickstart.md](quickstart.md).
 
+## Поток pipeline (ingest → render)
+
+1. **Scheduler** (`evobgp-scheduler` / in-process в `evobgp-all`) ставит `tenant_refresh`, если `ModuleDueForScheduler`: граница окна `refresh_interval_sec` со **сдвигом `fnv32(module.ID) % interval`**, чтобы модули с одним интервалом не били внешние API одновременно.
+2. **Ingest** (`RefreshModuleIngest`):
+   - `AS_PREFIXES` — RIPEstat prefixes + holder параллельно, кэш `asn_prefix_cache`; дедуп строк по `prefix + community`.
+   - `CDN_CIDRS` — единый `fetchCDNSourceRows` (conditional GET); prefetch уважает `RefreshIntervalSec`; merge снапшота под `LockModuleSnapshot` (пропущенные по ошибке источники сохраняют prior-строки при `EVOBGP_CDN_PARTIAL_OK`).
+   - `DOMAINS` — DoH A+AAAA параллельно; попадания в `domain_resolve_cache` с TTL `EVOBGP_DOMAIN_CACHE_TTL_SEC` (default 300).
+   - `IP_RANGES` — напрямую из записей модуля.
+3. Снапшот пишется **batch** (`pgx.CopyFrom` в PostgreSQL). Совпадение `module.input_hash` со снапшотом — O(1) пропуск повторного ingest при render; CRUD entries обнуляет hash.
+4. **Render** (`RenderTenantRevision`): `smartAggregatePrefixRows` (стек-схлопывание O(n log n), IPv6 без `math/big`) → ревизия, если набор префиксов изменился.
+
 ## Поток: ревизия и бандл для ноды
 
 1. Оператор (роль `operator` или выше по политике) изменяет модули и запускает цепочку, приводящую к новой **ревизии** (часть шагов может быть асинхронной через jobs — см. OpenAPI).
