Production-like MVP implementation described by `../architectory` and `../modules`.
The deployment entry point is `backend/docker-compose.yml`. Copy
`backend/.env.example` to `backend/.env`, provide external managed PostgreSQL,
Selectel S3 and Bitrix24 credentials, then follow `backend/deployment/RUNBOOK.md`.
The current executable entry point is `backend/docker-compose.yml`; it is the
legacy VM1/stub contour, not evidence that the VM2 cutover is complete.
Target production has two independent root Compose projects/systemd units:
VM1 HAN Chat (`backend/`) and private VM2 Processing (`message-safety`,
`bitrix-sync`, ClamAV, Redis Safety, internal nginx and a local OTEL Collector).
Until the VM2 project is implemented, follow the existing backend guide only
for development/acceptance and the target runbook in
`../modules/module-10-deployment-runbook.md` for migration boundaries.

## Схема
Приложения в Docker-сети отправляют OTLP локальному `otel-collector`:
Приложения на ВМ1 и ВМ2 отправляют OTLP только своему локальному `otel-collector`:
```text
HAN containers -> otel-collector:4317 -> 192.168.0.5:4317 -> SigNoz
VM1 containers -> VM1 otel-collector:4317 -> 192.168.0.5:4317 -> SigNoz
VM2 containers -> VM2 otel-collector:4317 -> 192.168.0.5:4317 -> SigNoz
```
Локальный Collector выполняет редактирование чувствительных атрибутов,
добавляет `service.namespace=han-chat`, окружение и версию, сохраняет очередь
на диск и пересылает данные в SigNoz.
Collectors имеют отдельные bounded persistent queue volumes. ВМ2 не использует
Docker hostname collector ВМ1. Недоступность SigNoz/Collector fail-open для
business/Safety readiness; переполнение очереди создаёт alert и controlled drop.
## Настройка backend
В `codebase/backend/.env`:
В non-secret env manifest каждой VM:
cd /opt/han-chat/backend

are managed external services. Never use `docker compose down -v`, an Alembic
downgrade, or a mutable image tag during deployment.
## VM2 Processing is a separate host
Do not run this backend/VM1 setup script on VM2. VM2 has its own bootstrap:
`codebase/services/deployment/scripts/setup-vm.sh`, and its authoritative
operator checklist is `codebase/services/deployment/RUNBOOK.ru.md`.
The VM2 ownership boundary is intentionally different from the legacy VM1
script: `deploy` is **not** a member of the `docker` group. Root owns
`/opt/han-chat/services`, Compose, units, helpers, `.env`, allow-lists and
secret mappings. Deploy may write only to `/var/lib/han-deploy/incoming` and
may invoke exact systemd/safety-mode commands installed in sudoers.
The separate `admin` account is break-glass only: it has its own Ed25519 key
and a separate local sudo password. Root, deploy and admin keys must differ.
Initial VM2 bootstrap commands:
```sh
# Local operator workstation: upload only the reviewed setup script.
scp codebase/services/deployment/scripts/setup-vm.sh \
root@<VM2_PUBLIC_IP>:/root/setup-vm2.sh
# VM2 root: install host packages/roles/firewalls; this does not start Compose.
chmod 0700 /root/setup-vm2.sh
DEPLOY_AUTHORIZED_KEY_FILE=/root/bootstrap/deploy.pub \
ADMIN_AUTHORIZED_KEY_FILE=/root/bootstrap/admin.pub \
OPS_CIDRS='<OPS_PUBLIC_IP>/32' \
VM1_PRIVATE_CIDRS='<VM1_PRIVATE_IP>/32' \
/root/setup-vm2.sh
```
Generate and upload the two public keys before this command; never copy the
root key into either account. Set the admin sudo password with `passwd admin`.
Keep the root session open and verify both key-based logins plus `sudo -v` as
admin in separate sessions. Only then rerun as VM2 root with
`HARDEN_SSH=true SKIP_APT_UPGRADE=true` to disable direct root SSH.
Release transfer is performed as deploy, while activation and installation
remain root operations:
```sh
# deploy: receive and inspect only.
cd /var/lib/han-deploy/incoming
sha256sum vm2-services-<RELEASE>.tar.gz
tar -tzf vm2-services-<RELEASE>.tar.gz
# root: verify the operator-provided digest, activate root-owned files,
# then rerun setup-vm.sh so it installs fixed helpers and systemd units.

```
After root configures `.env`, Selectel encrypted credentials, loader mapping,
TLS and CIDR allow-lists, root synchronizes secrets, runs preflight/migrations
and performs the first start. Subsequent routine operations available to
deploy are limited to:
```sh
sudo systemctl restart han-secrets-vm2.service
sudo systemctl restart han-processing.service
sudo systemctl --no-pager status han-processing.service
sudo journalctl --no-pager -u han-processing.service
```
Exact archive activation, file installation, credential creation, migration
and first-start commands are documented in the VM2 Russian runbook referenced
above. They must not be replaced with direct Docker access for deploy.
## Gate 0 — decisions and ownership
- [ ] Release SHA/digests, maintenance window, on-call and rollback owner recorded.

# bitrix-sync
Изолированный Python 3.12 сервис durable-синхронизации Contact между `han_app` и
Битрикс24. Сервис не участвует в Open Lines и не имеет HTTP-зависимости от
`api-backend`.
## Entrypoints
- `han-bitrix-sync-api` — health, internal status и два bounded robot receiver;
- `han-bitrix-sync-worker` — queue/webhook/rebind workflows с lease fencing;
- `han-bitrix-sync-reconciliation` — один advisory-lock incremental run;
- `alembic upgrade head` — отдельная контролируемая миграция, не startup DDL.
Disabled mode требует только `BITRIX_SYNC_ENABLED=false` и
`BITRIX_SYNC_MODE=disabled`, не читает БД и не принимает webhook. Full mode
валидирует весь каталог secret files, portal identity, custom fields, HTTPS host
lock и непустой CIDR allow-list до startup.
## Границы безопасности
- CRM credential URL используется как единый секрет; redirect выключен, TLS
проверяется, REST method выбирается только из закрытого allow-list.
- Receiver принимает только `application/x-www-form-urlencoded` с bounded
content length, числом и длиной полей. Query token сравнивается constant-time.
- nginx должен перезаписывать `X-Real-IP` из TCP peer, проверять CIDR до proxy и
не логировать `$request_uri`, args или body. Контейнер receiver недоступен
напрямую.
- DB хранит только hash CRM-master значений в snapshot; safe command projection
не содержит PII. URL credential, form body и token не логируются.
- Запись CRM-master полей выполняется в одной транзакции после
`SET LOCAL han.sync_suppress='true'`.
## Локальные проверки
Лёгкие проверки, не требующие Docker, сервиса или реального PostgreSQL:
```text
python -m pytest
python -m ruff check app tests
```
PostgreSQL integration и Bitrix contract suites намеренно являются внешними
gates: локальный managed PostgreSQL не поднимается Compose-файлом.
## External gates до `BITRIX_SYNC_ENABLED=true`
1. Применить migrations migration-role и проверить grants runtime-role.
2. На disposable managed PostgreSQL проверить concurrent `SKIP LOCKED`,
lease expiry/fencing, active mapping uniqueness, rebind partial failure,
transaction-local GUC без утечки и crash после CRM success.
3. Подтвердить на целевом портале wire-контракты `duplicate.findbycomm`,
Contact add/get/update, mixed `batch`, custom fields, enum dictionary и
`crm.item.list` с `opened=1`, registration REST field `=1`.
4. Заполнить и активировать валидную `business_alerts` settings version:
entity/category/stage/field IDs и responsible party. Placeholder `null`
запрещает alert receiver.
5. Проверить least-privilege credential negative tests; credential администратора
запрещён.
6. Валидировать nginx exact routes, no-redirect HTTP policy, body/rate limits,
version-controlled CIDR и отсутствие query/body в access/error/traces.
7. Запустить synthetic webhook с реальным robot form contract, затем убедиться,
что durable inbox commit предшествует `202`.
8. Выполнить 10k incremental reconciliation/load gate, webhook-loss recovery,
429/5xx/TLS/DNS/timeout/uncertain-create и restart-at-each-step tests.
9. Проверить container image digest, dependency/SBOM/vulnerability scan и
compose hardening; root Compose ВМ2 подключает этот fragment отдельно.
10. Зафиксировать cutover watermark, отменить только pre-cutover active tasks,
выполнить disabled preflight и затем controlled enablement.
`compose.fragment.yaml` — сервисный фрагмент, не root Compose и не команда
развёртывания. Reconciliation entrypoint выполняет один run; расписание задаёт
root-owned scheduler/deployment layer.

# VM2 Processing deployment runbook
This directory is the independent VM2 foundation. It does not deploy VM1 or
`codebase/backend`. All commands below are operator commands; repository
creation does not execute them.
## Production blockers before first start
1. Replace every `.env` placeholder with reviewed non-secret values. Keep
`BITRIX_SYNC_ENABLED=false` until migrations, grants, portal fields, robot
contracts and cutover are signed off.
2. Fill every `*_IMAGE` variable with a reviewed registry digest. Root Compose
rejects missing image references; mutable tags are not production evidence.
3. Install production files as `root:root`; `deploy` must not be in `docker`
and must not be able to write Compose, units, helpers, allow-lists or secret
mappings.
4. Populate separate reviewed active CIDR files from the two `.template`
files. Their committed active versions are intentionally `deny all`.
5. Provision public ACME material under host `/etc/letsencrypt` and the managed
PostgreSQL CA under `/etc/han/ca`. Provision an internal-CA certificate whose
SAN matches the private VM2 name. Permit host port `8443` only from VM1 SG
and, when needed, approved private/VPN ops CIDRs.
6. Create a dedicated VM2 Selectel IAM principal. It may read only names in
`deployment/secrets/config.example.json`. Never reuse the VM1 principal.
7. `REDIS_SAFETY_ACL` is the complete ACL file, not merely a password. It must
expose unauthenticated `PING` only for health and a password-protected
`safety` user limited to required `han:safety:*` keys/commands. The password
in `MESSAGE_SAFETY_REDIS_URL` must match. Start from
`redis/redis-safety.acl.template`, replace
`REPLACE_WITH_LONG_RANDOM_PASSWORD`, and never commit the password.
8. Provision distinct runtime and migration DB credentials.
`MESSAGE_SAFETY_CONFIG_ADMIN_DATABASE_URL` may migrate/activate policy while
`MESSAGE_SAFETY_DATABASE_URL` cannot; `BITRIX_SYNC_MIGRATION_DATABASE_URL`
owns DDL while `BITRIX_SYNC_DATABASE_URL` is the least-privilege runtime
role. Migration credentials are mounted only into the `ops` profile jobs.
9. The setup script leaves UFW egress open for bootstrap. Before production,
constrain egress through Selectel SG/NAT/proxy to the approved PostgreSQL,
S3, Secrets Manager, Bitrix24, DNS/NTP, SigNoz and ClamAV destinations.
Registry/package access exists only during controlled maintenance windows.
## Install
- Bootstrap a fresh Ubuntu 24.04 VM as root with
`deployment/scripts/setup-vm.sh`, supplying `VM1_PRIVATE_CIDRS`, optional
private/VPN `OPS_CIDRS`, and separate Ed25519 public-key files for deploy and
break-glass admin. SSH is publicly reachable but key-only and protected by
fail2ban; the CIDR variables apply only to private port `8443`. The script
installs host packages/firewalls and roles but never starts Compose. Set a
separate admin sudo password; verify deploy login, admin login and admin sudo
in independent sessions before rerunning with `HARDEN_SSH=true`.
Root/deploy/admin key reuse is rejected.
- Checkout an immutable release under `/opt/han-chat/services`.
- Copy `.env.example` to root-owned mode `0600` `.env`.
- Install `secrets_loader.py` and `han-secrets` under
`/usr/local/lib/han-secrets-vm2/`, root-owned and non-writable.
- Install `han-compose` as `/usr/local/sbin/han-vm2-compose`.
- Install `han-secrets-vm2.service` and `han-processing.service` under
`/etc/systemd/system/`.
- Install `han-message-safety-mode` as root-owned `0755` and the sudoers
template as `/etc/sudoers.d/deploy-message-safety-mode` mode `0440`; validate
with `visudo -cf`. Create the dedicated host group `han-message-safety` with
GID `10001`. Before the first Compose validation, create
`/etc/han-chat/message-safety-mode.env` as
`root:han-message-safety 0640` with all three flags `false` (or invoke the
helper's `standard` transition after the fixed launcher is installed).
- Install loader config using the exact `APP_ENV` suffix. With the committed
example (`APP_ENV=production-like`) the path is
`/etc/han/secrets/vm2-production-like.selectel.json` mode `0600`. For
controlled no-provider recovery use an explicit `file`
config pointing to a root-only `0700` directory containing exactly one file
per configured key. Selectel failure never falls back automatically.
## Preflight and startup
Run `deployment/preflight.sh` first. Then, through the approved root units:
1. synchronize secrets; any missing/oversized/invalid secret blocks startup;
2. validate resolved Compose without storing its output;
3. run the two `ops` migration jobs and create/activate the reviewed initial
Message Safety config before starting either runtime;
4. validate nginx config and both certificate chains;
5. start Redis/Collector, ClamAV, application API/workers, then nginx;
6. verify that only nginx publishes `80`, `443`, and private-bound `8443`;
7. verify all non-exact public paths return `404`, HTTP webhook paths return
`426` without redirect/query reflection, wrong methods fail, and wrong
source CIDRs are rejected before upstream;
8. verify private Safety check/task/status and sync status only from approved
callers; verify public `/internal/*` is `404`;
9. canary telemetry with a fake token marker and prove query, form body,
Authorization, DSN, S3 key and object key are absent from logs/traces.
Do not open webhook traffic while `bitrix-sync` is disabled. A disabled or
failed receiver must return retryable `503`/closed routing, never successful
`2xx ignored`.
## Failure policy
- Safety dependency failure is fail-closed: VM1 must not send/promote content.
- Stale/unavailable ClamAV signatures disable file capability only; they never
convert a scan error to allow.
- Redis loss may remove acceleration but PostgreSQL remains authoritative.
- OTEL outage queues within the bounded volume and must not change verdicts.
- Rollback does not downgrade schemas, delete durable tasks/mappings, or run
`docker compose down -v`.
## Emergency MOCK
Only these five sudo commands are allowed:
```text
han-message-safety-mode standard
han-message-safety-mode mock --text-free true --file-free true
han-message-safety-mode mock --text-free true --file-free false
han-message-safety-mode mock --text-free false --file-free true
han-message-safety-mode mock --text-free false --file-free false
```
The helper atomically writes only
`/etc/han-chat/message-safety-mode.env`, recreates only the Safety API, checks
health, and restores the previous mode on failure. MOCK has no timeout: keep a
high-severity alert active until explicit `standard`, then verify normal
text/link/file capabilities and an EICAR canary.
## Known image exceptions
ClamAV images may require UID/path adjustments after validating the exact
digest. Do not weaken `read_only`, capabilities or mounts globally: document
the smallest writable signature/runtime paths and compensate with network and
resource limits. `freshclam` alone receives signature-CDN egress; `clamd`
receives none.

# Ранбук развёртывания Processing на VM2
Этот каталог — независимая основа VM2. Он не разворачивает VM1 и не
затрагивает `codebase/backend`. Все команды ниже — операторские; создание
репозитория их не выполняет.
## Блокеры production перед первым запуском
1. Замените каждый плейсхолдер в `.env` на проверенные несекретные значения.
Держите `BITRIX_SYNC_ENABLED=false`, пока не подписаны миграции, гранты,
поля портала, контракты роботов и cutover.
(для этого нужно еще образы отправить в conteiner registry, пункт 2)
2. Заполните каждую переменную `*_IMAGE` проверенным digest из registry.
Корневой Compose отклоняет отсутствующие ссылки на образы; изменяемые
теги не являются доказательством для production.
3. Устанавливайте production-файлы от `root:root`; пользователь `deploy` не
должен входить в группу `docker` и не должен иметь возможность писать
Compose, unit-файлы, хелперы, allow-list’ы или маппинги секретов.
(смысл: заходим под админом, sudo -i)
4. Заполните отдельные проверенные активные CIDR-файлы из двух `.template`.
Их закоммиченные активные версии намеренно содержат `deny all`.
(в services/nginx/allowlist прописываем разрешенные адреса - адрес ВМ1 и адрес битрикса)
5. Выпустите публичный ACME-сертификат в host-каталог `/etc/letsencrypt`.
Разместите CA управляемой PostgreSQL в `/etc/han/ca`. Выпустите
сертификат внутренней CA, SAN которого совпадает с приватным именем VM2.
Разрешайте хостовый порт `8443` только из SG VM1 и, при необходимости,
одобренных приватных/VPN-сетей операторов.
(выпуск сертификатов)
6. Создайте отдельный IAM-принципал Selectel для VM2. Он может читать только
имена из `deployment/secrets/config.example.json`. Никогда не
переиспользуйте принципал VM1.
(отдельный проект в селектел, туда отдельного сервисного пользователя с ролью member)
7. `REDIS_SAFETY_ACL` — полный ACL-файл, а не просто пароль. Он должен
открывать неаутентифицированный `PING` только для health и
защищённого паролем пользователя `safety`, ограниченного необходимыми
ключами/командами `han:safety:*`.
(Пароль в `MESSAGE_SAFETY_REDIS_URL` должен совпадать. Используйте `redis/redis-safety.acl.template`, заменив `REPLACE_WITH_LONG_RANDOM_PASSWORD)
8. Выделите отдельные учётные данные БД для runtime и миграций.
`MESSAGE_SAFETY_CONFIG_ADMIN_DATABASE_URL` может мигрировать/активировать
политику, а `MESSAGE_SAFETY_DATABASE_URL` — нет; `BITRIX_SYNC_MIGRATION_DATABASE_URL`
владеет DDL, а `BITRIX_SYNC_DATABASE_URL` — runtime-роль с минимальными
привилегиями. Учётные данные миграций монтируются только в jobs профиля
`ops`.
9. Setup оставляет исходящий трафик UFW открытым на bootstrap-окно. До
production ограничьте egress правилами Selectel SG/NAT/proxy до
утверждённых PostgreSQL, S3, Secrets Manager, Bitrix24, DNS/NTP, SigNoz и
источников ClamAV. Registry/package repositories оставляйте только на
controlled maintenance window.
## Кто что выполняет
- **Локальный компьютер оператора:** создаёт архив релиза и передаёт его на
VM2. Локальные команды ниже показаны для PowerShell.
- **`root` на VM2:** только bootstrap host OS, активация проверенного релиза,
установка root-owned файлов, настройка `.env`, secret mapping, credentials,
TLS/allow-list, миграции и первый старт.
- **`deploy` на VM2:** принимает релиз только в
`/var/lib/han-deploy/incoming`, проверяет статус/логи и запускает уже
установленные fixed systemd operations через точные sudo-правила.
`deploy` не запускает `docker`, не редактирует `/opt/han-chat/services` и не
входит в группу `docker`.
- **`admin` на VM2:** персональная break-glass роль с отдельным SSH-ключом и
отдельным локальным паролем для `sudo`. Не используется для штатного деплоя,
не входит в `docker`/`lxd`; каждый вход и sudo-вызов считается инцидентной
операцией.
## 1. Bootstrap свежей VM2
На локальном компьютере один раз создайте **два разных** ключа. Закрытые части
остаются только у соответствующих операторов и никогда не передаются на VM:
```powershell
ssh-keygen -t ed25519 -a 100 -f C:\Users\MI\.ssh\han_vm2_deploy `
-C "han-vm2-deploy"
ssh-keygen -t ed25519 -a 100 -f C:\Users\MI\.ssh\han_vm2_admin `
-C "han-vm2-break-glass-admin"
```
Для production ключ `admin` должен принадлежать отдельному назначенному
break-glass оператору и храниться отдельно от deploy key. Если команды
выполняет один человек на этапе bootstrap, это всё равно две разные key pairs
с раздельной последующей передачей/ротацией.
Скопируйте setup-скрипт и только публичные части ключей во временный root
каталог:
```powershell
scp -i C:\Users\MI\.ssh\hansel `
.\HAN_chat_specification\codebase\services\deployment\scripts\setup-vm.sh `
root@<VM2_PUBLIC_IP>:/root/setup-vm2.sh
scp -i C:\Users\MI\.ssh\hansel `
C:\Users\MI\.ssh\han_vm2_deploy.pub `
C:\Users\MI\.ssh\han_vm2_admin.pub `
root@<VM2_PUBLIC_IP>:/root/
```
На VM2 в текущей root-сессии задайте приватный CIDR VM1. `/0` скрипт отклоняет:
```sh
install -d -m 0700 -o root -g root /root/bootstrap
install -m 0600 -o root -g root /root/han_vm2_deploy.pub /root/bootstrap/deploy.pub
install -m 0600 -o root -g root /root/han_vm2_admin.pub /root/bootstrap/admin.pub
chmod 0700 /root/setup-vm2.sh
DEPLOY_AUTHORIZED_KEY_FILE=/root/bootstrap/deploy.pub \
ADMIN_AUTHORIZED_KEY_FILE=/root/bootstrap/admin.pub \
VM1_PRIVATE_CIDRS='<PRIVATE_IP_VM1>/32' \
/root/setup-vm2.sh
```
Скрипт устанавливает Ubuntu-пакеты, Docker Engine + Compose plugin, UFW,
fail2ban, unattended upgrades, swap, sysctl и цепочку `DOCKER-USER`; создаёт
`deploy`, break-glass `admin`, staging и root-owned production-каталог. Скрипт
не запускает Compose/контейнеры. `80/443` и SSH открываются публично; SSH
остаётся key-only и защищён fail2ban. `8443` доступен только на приватном IP
VM2 из `VM1_PRIVATE_CIDRS`. Если оператору нужен прямой доступ к внутреннему
API через приватный маршрут или VPN, дополнительно передайте необязательный
`OPS_CIDRS='<OPS_PRIVATE_OR_VPN_CIDR>'`.
В текущей root-сессии задайте `admin` отдельный сложный sudo-пароль. Он не
разрешает password SSH: пароль нужен только после входа по admin key:
```sh
passwd admin
```
Не закрывая root-сессию, на локальном компьютере проверьте оба входа:
```powershell
ssh -i C:\Users\MI\.ssh\han_vm2_deploy deploy@<VM2_PUBLIC_IP>
ssh -i C:\Users\MI\.ssh\han_vm2_admin admin@<VM2_PUBLIC_IP>
```
В admin-сессии проверьте запрос именно admin-пароля и получение root shell,
после чего сразу выйдите из него:
```sh
sudo -v
sudo -i
id
exit
```
Только после успешной проверки `deploy`, `admin` и `sudo` повторите на VM2
под `root`:
```sh
DEPLOY_AUTHORIZED_KEY_FILE=/root/bootstrap/deploy.pub \
ADMIN_AUTHORIZED_KEY_FILE=/root/bootstrap/admin.pub \
VM1_PRIVATE_CIDRS='<PRIVATE_IP_VM1>/32' \
HARDEN_SSH=true \
SKIP_APT_UPGRADE=true \
/root/setup-vm2.sh
```
Это добавит `PermitRootLogin no` и `AllowUsers deploy admin`. Ещё раз откройте
обе новые SSH-сессии после reload и только затем закрывайте старую root.
Публичные bootstrap-копии после проверки можно удалить под `admin`:
```sh
sudo rm -f /root/han_vm2_deploy.pub /root/han_vm2_admin.pub
```
## 2. Передача релиза под `deploy`
На локальном компьютере из каталога `HAN_chat_specification`:
```powershell
$Release = "<VERSION_OR_GIT_SHA>"
tar --exclude=services/.env `
--exclude='services/**/__pycache__' `
--exclude='services/**/.pytest_cache' `
--exclude='services/**/.ruff_cache' `
-czf "vm2-services-$Release.tar.gz" -C .\codebase services
Get-FileHash "vm2-services-$Release.tar.gz" -Algorithm SHA256
scp -i C:\Users\MI\.ssh\hansel "vm2-services-$Release.tar.gz" `
deploy@<VM2_PUBLIC_IP>:/var/lib/han-deploy/incoming/
```
Под `deploy` на VM2 вычислите checksum. Значение должно совпасть с локальным:
```sh
RELEASE='<VERSION_OR_GIT_SHA>'
cd /var/lib/han-deploy/incoming
sha256sum "vm2-services-${RELEASE}.tar.gz"
tar -tzf "vm2-services-${RELEASE}.tar.gz"
```
На этом действия `deploy` с файлами заканчиваются. Не распаковывайте релиз
через `sudo` и не копируйте его в production от имени `deploy`.
## 3. Активация и установка файлов под `root`
Под `root` ещё раз сверьте ожидаемый SHA-256 и список архива. Не продолжайте,
если архив содержит абсолютные пути, `..`, symlink/hardlink или лишний проект:
```sh
RELEASE='<VERSION_OR_GIT_SHA>'
EXPECTED_SHA256='<SHA256_С_ЛОКАЛЬНОЙ_МАШИНЫ>'
ARCHIVE="/var/lib/han-deploy/incoming/vm2-services-${RELEASE}.tar.gz"
printf '%s %s\n' "$EXPECTED_SHA256" "$ARCHIVE" | sha256sum --check -
tar -tvzf "$ARCHIVE"
if tar -tzf "$ARCHIVE" | grep -Eq '(^/|(^|/)\.\.(/|$)|^services/\.env$)'; then
echo 'ОШИБКА: архив содержит небезопасный путь или .env' >&2
exit 1
fi
if tar -tzf "$ARCHIVE" | grep -Ev '^services(/|$)' | grep -q .; then
echo 'ОШИБКА: архив содержит файлы вне каталога services' >&2
exit 1
fi
if tar -tvzf "$ARCHIVE" | awk '$1 ~ /^[lh]/ { found=1 } END { exit !found }'; then
echo 'ОШИБКА: архив содержит symlink или hardlink' >&2
exit 1
fi
install -d -m 0755 -o root -g root /opt/han-chat/services
STAGING="$(mktemp -d /opt/han-chat/.vm2-release.XXXXXX)"
tar --extract --gzip --file "$ARCHIVE" \
--directory "$STAGING" --no-same-owner --no-same-permissions
test -f "$STAGING/services/docker-compose.yml"
rsync -a --delete --exclude=.env \
--chown=root:root --chmod=D755,F644 \
"$STAGING/services/" /opt/han-chat/services/
rm -rf -- "$STAGING"
chmod 0755 /opt/han-chat/services/deployment/preflight.sh
```
Повторите setup под `root`: теперь он установит helpers и units из активного
релиза. Приложение всё ещё не запускается:
```sh
DEPLOY_AUTHORIZED_KEY_FILE=/root/bootstrap/deploy.pub \
ADMIN_AUTHORIZED_KEY_FILE=/root/bootstrap/admin.pub \
VM1_PRIVATE_CIDRS='<PRIVATE_IP_VM1>/32' \
HARDEN_SSH=true \
SKIP_APT_UPGRADE=true \
/root/setup-vm2.sh
```
Скрипт устанавливает:
- `/usr/local/lib/han-secrets-vm2/{secrets_loader.py,han-secrets}`;
- `/usr/local/sbin/han-vm2-compose`;
- `/usr/local/sbin/han-message-safety-mode`;
- `/etc/letsencrypt/renewal-hooks/deploy/han-processing-nginx`;
- `/etc/systemd/system/{han-secrets-vm2,han-processing}.service`;
- `/etc/sudoers.d/{han-vm2-deploy,deploy-message-safety-mode}`;
- группу `han-message-safety` с GID `10001`;
- стандартный `/etc/han-chat/message-safety-mode.env` с правами
`root:han-message-safety 0640`.
## 4. Несекретная конфигурация и Selectel под `root`
`APP_ENV` определяет имя loader config. При значении из `.env.example`
`APP_ENV=production-like` файл обязан называться
`/etc/han/secrets/vm2-production-like.selectel.json`:
```sh
cd /opt/han-chat/services
install -m 0600 -o root -g root .env.example .env
editor .env
install -m 0600 -o root -g root \
deployment/secrets/config.example.json \
/etc/han/secrets/vm2-production-like.selectel.json
editor /etc/han/secrets/vm2-production-like.selectel.json
```
В `.env` заменяются только несекретные плейсхолдеры и image digests. Значения
DSN, token, password, access/secret key туда не записываются. Для Selectel
создайте отдельный VM2 IAM principal с read-only доступом только к remote names
из mapping.
Зашифруйте пароль Selectel service user через systemd credentials, не помещая
его в аргументы или history:
```sh
read -rsp 'Selectel VM2 service-user password: ' SELECTEL_PASSWORD; echo
printf '%s' "$SELECTEL_PASSWORD" | systemd-creds encrypt \
--name=selectel-service-user-password - \
/etc/han/credentials/vm2.selectel-password.cred
unset SELECTEL_PASSWORD
chown root:root /etc/han/credentials/vm2.selectel-password.cred
chmod 0600 /etc/han/credentials/vm2.selectel-password.cred
```
Активные nginx allow-list файлы редактирует только `root`; последней строкой
обязательно остаётся `deny all;`. До cutover Bitrix public allow-list должен
оставаться закрытым:
```sh
editor /opt/han-chat/services/nginx/allowlists/private-caller-allowlist.conf
editor /opt/han-chat/services/nginx/allowlists/bitrix-webhook-allowlist.conf
chown root:root /opt/han-chat/services/nginx/allowlists/*.conf
chmod 0644 /opt/han-chat/services/nginx/allowlists/*.conf
```
Для контролируемого восстановления без провайдера используйте явный `file`
config и root-only каталог `0700` с одним файлом на ключ. При сбое Selectel
автоматический fallback запрещён.
## 5. Сертификат PostgreSQL и первоначальный выпуск public TLS
### CA управляемой PostgreSQL
Скачайте CA-сертификат кластера из панели провайдера и передайте его на VM2 во
временный путь. Под `root` установите сертификат вне каталога релиза:
```sh
install -d -m 0755 -o root -g root /etc/han/ca
install -m 0644 -o root -g root \
/tmp/<PROVIDER_POSTGRESQL_CA_FILE> \
/etc/han/ca/managed-postgresql-ca.pem
openssl x509 -in /etc/han/ca/managed-postgresql-ca.pem \
-noout -subject -issuer -dates
rm -f /tmp/<PROVIDER_POSTGRESQL_CA_FILE>
```
В `.env` должно быть:
```dotenv
PG_CA_HOST_PATH=/etc/han/ca/managed-postgresql-ca.pem
```
Compose монтирует этот файл read-only во все runtime и migration контейнеры как
`/run/config/postgresql-ca.pem`. DB-клиенты создают обязательный TLS context с
проверкой цепочки и имени сервера по этому CA. Не добавляйте libpq-параметры
`sslmode`/`sslrootcert` в SQLAlchemy `postgresql+asyncpg` URL: asyncpg получает
SSL context отдельно, а такие query-параметры могут быть переданы как
неподдерживаемые keyword arguments. DSN в Secrets Manager имеет обычный вид:
```text
postgresql+asyncpg://<USER>:<PASSWORD>@<MANAGED_POSTGRES_HOST>:<PORT>/<DATABASE>
```
### Первоначальный выпуск Let's Encrypt
`PROCESSING_PUBLIC_HOST` должен быть DNS-именем, A-запись которого уже указывает
на публичный IP VM2. Сертификат на IP-адрес этим порядком не выпускается. Порт
`80` должен быть разрешён в cloud firewall/UFW и пока не занят nginx.
Под `root` задайте значения только для текущей shell-сессии и подготовьте
постоянный webroot:
```sh
PUBLIC_HOST='<PROCESSING_PUBLIC_HOST>'
ACME_EMAIL='<ADMIN_EMAIL>'
install -d -m 0755 -o root -g root /var/lib/han-chat/acme
getent ahostsv4 "$PUBLIC_HOST"
ss -lntp | grep -E ':80[[:space:]]' && {
echo 'Порт 80 уже занят; остановите listener перед standalone-проверкой' >&2
exit 1
} || true
```
Сначала проверьте ACME через staging CA. Этот сертификат nginx не использует:
```sh
certbot certonly --standalone --preferred-challenges http \
--staging \
-d "$PUBLIC_HOST" \
--cert-name "${PUBLIC_HOST}-staging" \
--email "$ACME_EMAIL" \
--agree-tos --no-eff-email --non-interactive
certbot delete --cert-name "${PUBLIC_HOST}-staging" --non-interactive
```
После успешного staging-теста выпустите production-сертификат:
```sh
certbot certonly --standalone --preferred-challenges http \
-d "$PUBLIC_HOST" \
--cert-name "$PUBLIC_HOST" \
--email "$ACME_EMAIL" \
--agree-tos --no-eff-email --non-interactive
certbot certificates
test -s "/etc/letsencrypt/live/${PUBLIC_HOST}/fullchain.pem"
test -s "/etc/letsencrypt/live/${PUBLIC_HOST}/privkey.pem"
getent group han-nginx-tls
test -d /var/lib/han-chat/public-tls
install -m 0640 -o root -g han-nginx-tls \
"/etc/letsencrypt/live/${PUBLIC_HOST}/fullchain.pem" \
/var/lib/han-chat/public-tls/fullchain.pem
install -m 0640 -o root -g han-nginx-tls \
"/etc/letsencrypt/live/${PUBLIC_HOST}/privkey.pem" \
/var/lib/han-chat/public-tls/privkey.pem
```
Nginx с primary GID `11001` получает только подготовленные public certificate
и private key из `/var/lib/han-chat/public-tls` с host read-only. Исходный
`/etc/letsencrypt` остаётся доступен только root/Certbot. Не копируйте private
key в каталог релиза и не делайте его world-readable.
## 6. Preflight, миграции и первый запуск под `root`
Сначала синхронизируйте секреты. Затем выполните статический preflight:
```sh
systemctl start han-secrets-vm2.service
/opt/han-chat/services/deployment/preflight.sh
/usr/local/sbin/han-vm2-compose config --quiet
```
До runtime выполните миграции отдельными DB roles и активируйте начальный
Message Safety config:
Перед первым `bitrix-sync-migrate` владелец `han_app` или администратор БД
выдаёт Bitrix migration-role временный read-only доступ к legacy mapping:
```sql
GRANT USAGE ON SCHEMA han_app TO <BITRIX_SYNC_MIGRATION_ROLE>;
GRANT SELECT ON TABLE han_app.entity_external_mapping
TO <BITRIX_SYNC_MIGRATION_ROLE>;
```
```sh
/usr/local/sbin/han-vm2-compose --profile ops run --rm message-safety-migrate
/usr/local/sbin/han-vm2-compose --profile ops run --rm bitrix-sync-migrate
/usr/local/sbin/han-vm2-compose --profile ops run --rm \
--entrypoint message-safety-config message-safety-migrate \
create /app/app/artifacts/seed-config.yaml --version 1 --actor '<OPERATOR>'
/usr/local/sbin/han-vm2-compose --profile ops run --rm \
--entrypoint message-safety-config message-safety-migrate \
activate --version 1 --approved-by '<APPROVER>'
```
После успешного `bitrix-sync-migrate` администратор БД отзывает временные
права. Право `USAGE` отзывайте только если оно не требуется этой роли для
других согласованных операций:
```sql
REVOKE SELECT ON TABLE han_app.entity_external_mapping
FROM <BITRIX_SYNC_MIGRATION_ROLE>;
REVOKE USAGE ON SCHEMA han_app FROM <BITRIX_SYNC_MIGRATION_ROLE>;
```
Первый запуск и enable выполняет `root` только после прохождения gates:
(внутри gate5)
```sh
systemctl enable han-secrets-vm2.service han-processing.service
systemctl start han-processing.service
systemctl --no-pager status han-processing.service
journalctl --no-pager -u han-processing.service
```
Дальнейшие штатные операции может выполнить `deploy`:
```sh
sudo systemctl restart han-secrets-vm2.service
sudo systemctl restart han-processing.service
sudo systemctl --no-pager status han-processing.service
sudo journalctl --no-pager -u han-processing.service
```
Установка/редактирование unit, Compose, `.env`, secret mapping, credential,
TLS, allow-list и запуск migration jobs остаются операциями `root`.
### Gate 1 — секреты материализованы
Под `root` на VM2:
```sh
systemctl restart han-secrets-vm2.service
systemctl is-active han-secrets-vm2.service
journalctl --no-pager -u han-secrets-vm2.service
test -s /run/han-chat/secrets/manifest
cut -d= -f1 /run/han-chat/secrets/manifest | sort
```
Ожидается `active`; журнал не содержит значений секретов; последняя команда
показывает только имена всех ключей из mapping. Не выполняйте `cat` файлов
секретов и не вставляйте реальные значения в terminal history.
### Gate 2 — статический preflight и Compose
Под `root` на VM2:
```sh
cd /opt/han-chat/services
deployment/preflight.sh
/usr/local/sbin/han-vm2-compose config --quiet
/usr/local/sbin/han-vm2-compose config --services
/usr/local/sbin/han-vm2-compose config --images
```
Все команды должны завершиться с кодом `0`. В списке services нет PostgreSQL,
а все production images содержат `@sha256:`. Вывод полного resolved Compose в
файл не сохраняйте.
### Gate 3 — миграции и активный Message Safety config
Команды миграций из предыдущего раздела выполняются под `root`. После них:
```sh
/usr/local/sbin/han-vm2-compose --profile ops run --rm \
message-safety-migrate current
/usr/local/sbin/han-vm2-compose --profile ops run --rm \
bitrix-sync-migrate current
```
Ожидается по одной head revision каждого сервиса. `create --version 1`
выполняется только при первом развёртывании. Для следующего конфига используйте
новый монотонный номер и отдельные значения `--actor`/`--approved-by`; повторно
активировать старую версию нельзя. Alembic downgrade запрещён.
### Gate 4 — конфигурация nginx до запуска
После выпуска public TLS в `/etc/letsencrypt` и материализации internal TLS
secrets. В Selectel значения `VM2_INTERNAL_TLS_CERTIFICATE` и
`VM2_INTERNAL_TLS_PRIVATE_KEY` сохраняются как исходный PEM с настоящими
переводами строк, не как повторный base64 и не как строка с литералами `\n`.
После изменения remote secret перезапустите `han-secrets-vm2.service`; preflight
проверит формат PEM и соответствие certificate/key без вывода их содержимого:
```sh
/opt/han-chat/services/deployment/preflight.sh
/usr/local/sbin/han-vm2-compose run --rm --no-deps \
-e MESSAGE_SAFETY_UPSTREAM_HOST=127.0.0.1 \
-e BITRIX_SYNC_UPSTREAM_HOST=127.0.0.1 \
nginx \
nginx -t -c /etc/nginx/nginx.conf
```
Базовый `nginx.conf` подключает обязательный
`/etc/nginx/conf.d/10-vm2.conf`, поэтому команда завершится ошибкой, если
entrypoint не создал конфигурацию из шаблона. Временные значения upstream
нужны только для проверки до первого запуска backend-контейнеров; production
Compose подставляет DNS-имена сервисов. Ожидается `syntax is ok` и `test is
successful`; ошибок `conf.d is not writable` и предупреждения о превышении
open-file limit быть не должно. Ошибка отсутствующего сертификата является
блокером, а не основанием временно убрать TLS.
### Gate 5 — упорядоченный первый запуск
Под `root` на VM2:
```sh
/usr/local/sbin/han-vm2-compose up -d redis-safety otel-collector
/usr/local/sbin/han-vm2-compose up -d freshclam clamd
/usr/local/sbin/han-vm2-compose up -d \
message-safety-api message-safety-worker
/usr/local/sbin/han-vm2-compose up -d \
bitrix-sync bitrix-sync-worker bitrix-sync-reconciliation
/usr/local/sbin/han-vm2-compose up -d nginx
/usr/local/sbin/han-vm2-compose ps
```
`otel-collector` автоматически запускает одноразовый `otel-queue-init`. Он
выставляет владельца persistent queue `10001:10001` и завершается с кодом `0`;
сам Collector стартует только после этого.
Healthcheck nginx использует встроенный `nginx -t`: утверждённый
`nginx-unprivileged` image не содержит `wget`/`curl`. `ExitCode 127` с
сообщением `wget: not found` означает, что на VM2 остался старый Compose.
Если запуск выполнялся со старым релизом и Message Safety уже попал в
permission/restart loop, после активации исправленного релиза под `root`
восстановите контракт файла и пересоздайте затронутые контейнеры:
```sh
getent group 10001 >/dev/null ||
groupadd --system --gid 10001 han-message-safety
test "$(getent group han-message-safety | cut -d: -f3)" = 10001
chown root:han-message-safety /etc/han-chat/message-safety-mode.env
chmod 0640 /etc/han-chat/message-safety-mode.env
install -m 0755 -o root -g root \
/opt/han-chat/services/deployment/han-message-safety-mode \
/usr/local/sbin/han-message-safety-mode
/opt/han-chat/services/deployment/preflight.sh
/usr/local/sbin/han-vm2-compose up -d --force-recreate \
otel-queue-init otel-collector
/usr/local/sbin/han-vm2-compose up -d --force-recreate \
message-safety-api message-safety-worker
/usr/local/sbin/han-vm2-compose ps
```
Не заменяйте это на `chmod 0644/0666`, запуск контейнеров от root или
рекурсивный `chown` Docker volumes. Если после восстановления прав nginx
остаётся в `Restarting`, это отдельная ошибка конфигурации/TLS, а не права
Message Safety; проверьте её без вывода секретов:
```sh
/usr/local/sbin/han-vm2-compose logs --tail 100 nginx otel-collector
```
Дождитесь `healthy` у сервисов с healthcheck. Не продолжайте при
`Restarting`, `unhealthy`, OOM или неожиданном `Exited`. После успешного
первого запуска передайте дальнейший lifecycle systemd:
```sh
systemctl enable han-secrets-vm2.service han-processing.service
systemctl start han-processing.service
systemctl --no-pager status han-processing.service
```
### Gate 6 — host ports и сертификаты
Под `root` на VM2:
```sh
ss -lntp | grep -E ':(80|443|8443|6379|8080|4317|4318)[[:space:]]'
/usr/local/sbin/han-vm2-compose ps --format json | jq .
```
Ожидаются host listeners только nginx: public `80`, `443` и private-bound
`8443` на `PROCESSING_PRIVATE_BIND_ADDRESS`. `6379`, container `8080` и OTLP
`4317/4318` на host отсутствуют.
С доверенной рабочей станции проверьте public chain:
```sh
openssl s_client -connect <PROCESSING_PUBLIC_HOST>:443 \
-servername <PROCESSING_PUBLIC_HOST> \
-verify_hostname <PROCESSING_PUBLIC_HOST> -verify_return_error </dev/null
```
С VM1 или ops host, имеющего private route, проверьте internal chain и SAN:
```sh
openssl s_client -connect <VM2_PRIVATE_IP>:8443 \
-servername <VM2_PRIVATE_DNS_NAME> \
-verify_hostname <VM2_PRIVATE_DNS_NAME> \
-CAfile <INTERNAL_CA_FILE> -verify_return_error </dev/null
```
Обе команды должны завершить certificate verification без ошибки.
Переключите renewal с первоначального `standalone` на webroot, который nginx
обслуживает по `/.well-known/acme-challenge/`. `certbot reconfigure` сам
проверит новый способ через staging CA:
```sh
PUBLIC_HOST='<PROCESSING_PUBLIC_HOST>'
certbot reconfigure \
--cert-name "$PUBLIC_HOST" \
--authenticator webroot \
--webroot-path /var/lib/han-chat/acme
```
Повторный setup после активации релиза устанавливает deploy-hook
`/etc/letsencrypt/renewal-hooks/deploy/han-processing-nginx`: после успешного
обновления он атомарно размещает certificate/key с группой `han-nginx-tls` в
`/var/lib/han-chat/public-tls`, проверяет конфигурацию nginx и отправляет
контейнеру `HUP`.
Проверьте полный цикл и включите штатное расписание Certbot:
```sh
test -x /etc/letsencrypt/renewal-hooks/deploy/han-processing-nginx
certbot renew --dry-run --run-deploy-hooks
systemctl enable --now certbot.timer
systemctl --no-pager status certbot.timer
systemctl list-timers certbot.timer
```
`certbot.timer` проверяет необходимость продления дважды в сутки; сертификат
перевыпускается только при приближении срока. Ошибка dry-run или deploy-hook —
блокер. Итог `Congratulations, all simulated renewals succeeded` означает
успешный dry-run. Старый hook мог при этом дать ложное
`Hook 'deploy-hook' ran with error output`: Compose писал `Killing/Killed`, а
успешный `nginx -t` — `syntax is ok` в stderr. Исправленный hook показывает
вывод config test только при ненулевом exit code и использует тихий
`docker kill --signal HUP`. Порт `80` после этого остаётся доступен для
HTTP-01 renewal.
### Gate 7 — public routing
С внешней тестовой машины:
```sh
curl -sS -o /dev/null -w '%{http_code}\n' \
http://<PROCESSING_PUBLIC_HOST>/not-a-route
curl -sS -o /dev/null -w '%{http_code}\n' \
https://<PROCESSING_PUBLIC_HOST>/not-a-route
curl -sS -o /dev/null -w '%{http_code}\n' \
http://<PROCESSING_PUBLIC_HOST>/bitrix/sync/webhook/contact
curl -sS -o /dev/null -w '%{http_code}\n' \
https://<PROCESSING_PUBLIC_HOST>/internal/safety/status
curl -sS -o /dev/null -w '%{http_code}\n' -X GET \
https://<PROCESSING_PUBLIC_HOST>/bitrix/sync/webhook/contact
```
Ожидаемые коды по порядку: `308`, `404`, `426`, `404`, `405`. Для HTTPS
используйте только валидный public certificate, без `-k`.
POST к webhook с адреса вне Bitrix allow-list должен получить `403`; если
cloud firewall настроен на drop, допустим timeout. Затем повторите с
разрешённого source IP и заведомо неверным receiver token: upstream должен
ответить `403`, не `2xx`.
### Gate 8 — private API только с VM1/ops
Следующие команды выполняются **на VM1** или approved ops host, не на VM2.
Используйте private DNS/SAN и внутреннюю CA.
Safety status:
```sh
curl --fail --silent --show-error \
--cacert <INTERNAL_CA_FILE> \
https://<VM2_PRIVATE_DNS_NAME>:8443/internal/safety/status
```
Benign text check через тот же private listener:
```sh
SAFETY_TOKEN="$(cat <MESSAGE_SAFETY_SERVICE_TOKEN_FILE_ON_VM1>)"
MESSAGE_ID="$(uuidgen)"
curl --silent --show-error --write-out '\nHTTP %{http_code}\n' --config - <<EOF
url = "https://<VM2_PRIVATE_DNS_NAME>:8443/internal/safety/v2/messages/check"
cacert = "<INTERNAL_CA_FILE>"
request = "POST"
header = "X-Service-Token: ${SAFETY_TOKEN}"
header = "Content-Type: application/json"
data = "{\"message_id\":\"${MESSAGE_ID}\",\"content_kind\":\"text\",\"text\":\"VM2 safety canary\",\"attachment\":null}"
EOF
unset SAFETY_TOKEN MESSAGE_ID
```
В standard mode ожидается `HTTP 200`, `verdict=allow` и непустые
`config_version`/`rules_version`. Проверку `202 → Location → task GET`
выполняйте отдельным file smoke только с реальным versioned quarantine object:
выдуманные S3 key/version/ETag не являются валидным тестом.
Для Bitrix status прочитайте token из уже защищённого secret file VM1 в
переменную и передайте curl config через stdin, чтобы значение не попало в
argv/history:
```sh
BITRIX_TOKEN="$(cat <BITRIX_SYNC_SERVICE_TOKEN_FILE_ON_VM1>)"
curl --silent --show-error --output /tmp/vm2-sync-status.json \
--write-out '%{http_code}\n' --config - <<EOF
url = "https://<VM2_PRIVATE_DNS_NAME>:8443/internal/sync/v1/status"
cacert = "<INTERNAL_CA_FILE>"
header = "Authorization: Bearer ${BITRIX_TOKEN}"
EOF
unset BITRIX_TOKEN
cat /tmp/vm2-sync-status.json
rm -f /tmp/vm2-sync-status.json
```
При `BITRIX_SYNC_ENABLED=false` ожидается закрытая/неготовая синхронизация, а
не ложный успешный full-mode status. С машины вне `VM1_PRIVATE_CIDRS` и
необязательных приватных/VPN-сетей `OPS_CIDRS` подключение к `8443` должно
завершиться timeout/reject.
### Gate 9 — canary на отсутствие секретов в логах и traces
Создайте **фейковый**, не production token marker и отправьте его с
разрешённого тестового source IP:
```sh
CANARY="HAN_VM2_REDACTION_$(date +%s)"
curl -sS -o /dev/null \
-H "Authorization: Bearer ${CANARY}" \
-H 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode "auth[application_token]=${CANARY}" \
"https://<PROCESSING_PUBLIC_HOST>/bitrix/sync/webhook/contact?token=${CANARY}"
```
На VM2 под `root`:
```sh
CANARY='<ЗНАЧЕНИЕ_CANARY_С_ТЕСТОВОЙ_МАШИНЫ>'
if /usr/local/sbin/han-vm2-compose logs --no-color \
nginx bitrix-sync message-safety-api otel-collector |
grep -F -- "$CANARY"; then
echo 'FAIL: canary попал в логи' >&2
exit 1
fi
unset CANARY
```
В SigNoz выполните поиск этого же marker по logs и span attributes за окно
теста: результат должен быть пустым. Отдельными фейковыми markers повторите
проверку для DSN-подобной строки, S3 key и object key. Реальные secrets для
такой проверки не используйте.
Не открывайте webhook-трафик, пока `bitrix-sync` отключён. Отключённый или
упавший receiver должен возвращать retryable `503`/закрытую маршрутизацию,
никогда успешный `2xx ignored`.
## Политика отказов
- Отказ зависимости Safety — fail-closed: VM1 не должна отправлять/продвигать
контент.
- Устаревшие/недоступные сигнатуры ClamAV отключают только файловую
capability; ошибка сканирования никогда не превращается в allow.
- Потеря Redis может убрать ускорение, но PostgreSQL остаётся источником
истины.
- Сбой OTEL ставит в очередь в пределах ограниченного тома и не должен
менять вердикты.
- Rollback не понижает схемы, не удаляет durable tasks/mappings и не
запускает `docker compose down -v`.
## Аварийный MOCK
Разрешены только эти пять sudo-команд:
```text
han-message-safety-mode standard
han-message-safety-mode mock --text-free true --file-free true
han-message-safety-mode mock --text-free true --file-free false
han-message-safety-mode mock --text-free false --file-free true
han-message-safety-mode mock --text-free false --file-free false
```
Хелпер атомарно пишет только
`/etc/han-chat/message-safety-mode.env`, пересоздаёт только Safety API,
проверяет health и при сбое восстанавливает предыдущий режим. У MOCK нет
таймаута: держите high-severity alert активным до явного `standard`, затем
проверьте нормальные text/link/file capabilities и EICAR-canary.
## Известные исключения по образам
Образы ClamAV могут потребовать корректировок UID/path после валидации
точного digest. Не ослабляйте `read_only`, capabilities или mounts глобально:
задокументируйте минимальные writable пути для сигнатур/runtime и
компенсируйте сетевыми и ресурсными лимитами. Egress к signature-CDN
получает только `freshclam`; `clamd` — нет.

# Первичная подготовка Ubuntu 24.04 для HAN Chat VM2 Processing.
#
# Скрипт устанавливает host-зависимости, Docker/Compose, создаёт непривилегированную
# роль deploy, настраивает SSH/UFW/fail2ban/DOCKER-USER/swap и устанавливает
# root-owned deployment helpers, если релиз уже размещён в DEPLOY_DIR.
#
# PostgreSQL, S3, Selectel IAM, DNS, TLS, образы, .env и значения секретов
# скрипт не создаёт. Он не запускает Compose и прикладные контейнеры.
#
# Первый запуск на свежей VM выполняется root:

# ADMIN_AUTHORIZED_KEY_FILE=/root/bootstrap/admin.pub \

3. В сессии admin проверьте sudo -v и sudo -i, затем завершите root shell.
4. Передайте релиз в ${INCOMING_DIR} от имени deploy.
5. Активируйте проверенный релиз в ${DEPLOY_DIR} от root:root.
6. Повторите этот скрипт от root для установки helpers и units.
7. Настройте .env, Selectel credential/config и TLS от root.
8. Выполните deployment/preflight.sh от root.
9. После успешных gates запускайте только утверждённые systemd units.
Deploy не входит в docker group и не изменяет production-файлы.
Скрипт не запускал Compose или прикладные сервисы.

# HAN Message Safety v2
Production-oriented internal FastAPI service for deterministic text, URL and quarantined-file
safety checks. PostgreSQL is the durable source of truth for idempotency, tasks, leases, fencing,
caches, audit and immutable config snapshots. Redis is intentionally optional and may only
accelerate hot-cache/rate/wakeup paths.
## Local verification
Python 3.12 is required. These commands do not start services:
```sh
python -m pip install -e ".[dev]"
pytest
ruff check .
message-safety-config validate app/artifacts/seed-config.yaml
```
Migrations and config administration require
`MESSAGE_SAFETY_CONFIG_ADMIN_DATABASE_URL_FILE`. Runtime secrets are accepted only through
`*_FILE`; the entrypoint rejects missing/empty files without printing their values.

## Deployment boundary
`docker-compose.fragment.yml` is an include fragment for the root VM2 Compose. It publishes no
host port, runs API and worker as UID 10001 with a read-only filesystem, drops all capabilities,
and mounts only service-specific secret files. The root project owns networks/secrets and the
root-owned emergency mode file.
## External release gates
The following cannot be proven by repository-only tests and must remain fail-closed until the
target environment verifies them:
- Selectel S3 supports version-specific `GetObject`, signed conditional ETag behavior, bucket
versioning, checksum metadata, virtual-host addressing and a read-only IAM policy without
list/write/delete.
- ClamAV engine/signature metadata is supplied to readiness and task cache keys; freshclam
activate/reload, signature-age alarms and clean/EICAR/malformed corpora pass on VM2.
- HEIF native decoding and PDF parser sandbox resource limits pass the approved corpus. The
in-process detector is bounded by 5 MiB and validates active/encrypted PDF markers, but OS-level
CPU/memory/wall-time isolation must be enforced by the worker container and target runtime.
- Managed PostgreSQL role grants prove runtime cannot migrate or activate config, while the
config-admin role can; migration constraint, concurrent activation, lease and fencing tests run
against PostgreSQL (not SQLite).
- Trusted resolver, DNS rebinding corpus, S3 canary and worker heartbeat are wired into production
readiness probes.
- Image dependencies are resolved to a reviewed lock/SBOM and the final image is pinned by digest
in the root Compose release manifest.
- Target load gates (10 text checks/s, 2 file checks/s, 100 pending tasks, five worker slots) and
privacy/log redaction are verified in production-like infrastructure.
No HTTP fetch, redirect following or rendering of user-provided URLs exists in this service.
