# Wiki op-log

Append-only log of wiki operations (ingests, promotions, lints, migrations).

## [2026-06-08] update | entities/windows-recovery-host — декоммишн после Synology-recovery: снесены traefik/mssql/minio/imgproxy/es + 21 husk-стек + VM snolla-recovery (95ГБ) + C:\nas-recovery (~150ГБ) + IIS-сайт snolla + C:\sites\snolla + локальный MSSQL. Осталось: IIS stostayer/stostayer.old (репойнт на mssql.kzntsv.site, orphan-fix), lightrag, markitdown-MCP, mutable-dev VM. C: free 62→275ГБ (+~176ГБ docker pending vhdx-compact). image-pipeline SPOF снят. Источник: `.tasks/decommission-windows-recovery-host.md`.

## [2026-06-08] ingest | concepts/morethencms-null-settingsdata-https-502 — RCA+fix: `maljarka.tandemmebel.ru` отдавал 502 только на HTTPS (HTTP=200). Корень = `dbo.Sites.SettingsData=NULL` у тенанта maljarka (нет блока `httpSecure`) → `KeyNotFoundException` в `SnollaMiddleware`/`Owin.ErrorHandler` на HTTPS-ветке. Fix = `UPDATE dbo.Sites SET SettingsData='{httpSecure:...}'` + `Restart-WebAppPool snolla`; verified 443→200 server-local + external. Audit: maljarka — единственный NULL-сайт с :443-биндингом; rimiz degraded по другой причине. Обновлён [[../entities/ruvds-iis-host]]. Источник: live-диагностика 2026-06-08.

## [2026-06-05] ingest | concepts/winacme-iis-owin-catchall-http01 — постоянный self-renewing LE pipeline на RUVDS IIS (win-acme v2.2.9, 25-SAN cert, SYSTEM scheduled task). Главное: OWIN-catch-all CMS жрёт `/.well-known/acme-challenge/` → решено отдельным IIS-приложением в пуле «No Managed Code» + патч шаблона `Web_Config.xml` (snять Owin-handler). Заменяет ручной [[traefik-acme-json-to-iis-cert-import]] для renewal'а; снимает зависимость RUVDS от домашнего traefik. Закрывает дедлайн cert-expiry 2026-07-22 (новый cert до 2026-09-03). Источник: `.tasks/iis-migration-to-ruvds.md` Decisions log 2026-06-05.

## [2026-05-28] ingest | concepts/es-destructive-delete-incident-2026-05-26 — RCA для удаления 3 user-индексов на canonical ES `elasticsearch.kzntsv.site` (books VDS stack 33) во время cutover-prep. Caller identity unrecoverable (audit log = X-Pack платный, traefik accessLog был выключен). 2 preventive controls applied + verified: ES env `action.destructive_requires_name=true` + traefik JSON accessLog. Источник: `.tasks/restore-elasticsearch-indices-books-vds.md` § Closure note.

## 2026-05-21

- bootstrap: empty wiki skeleton (CLAUDE.md, index.md, log.md, overview.md, raw/README.md) committed

## [2026-05-21] ingest | concepts/admin-infra-project

## [2026-05-21] seed | CLAUDE.md Domain conventions — design-context pointers (task: admin-infra-project-pointers)

## [2026-05-21] migrate | subtree-import 6 entities + 17 concepts + 3 sources from MoreThenCms (history preserved via subtree-split + temp-prefix merge)

## [2026-05-21] regen | index.md catalog refresh after subtree import

## [2026-05-21] ingest | concepts/ocis-on-vds-deploy-recipe — oCIS deploy recipe + gotchas (UID mismatch, PROXY_TLS, PROXY_ENABLE_BASIC_AUTH, LibreGraph user-create); updated entities/vds-kzntsv (added owncloud row to stack/hostnames/file-layout); source: .tasks/owncloud-vds-deploy.md

## [2026-05-22] update | concepts/ocis-on-vds-deploy-recipe — Gotcha 5: 60s HTTP timeout caps slow-uplink uploads at ~200MB on 3 MiB/s link; traefik buffering NOT the fix (500 from oxy buffer); workaround = VDS-side curl PUT loopback via throwaway sftp key. Source: .tasks/owncloud-vds-deploy.md close-note.

## [2026-05-23] ingest | concepts/windows-server-2025-core-bootstrap — default-blockers (SMB closed, IIS/URL-Rewrite/.NET unverified) + transfer-методов матрица (RDP-redirect / SMB / WinRM / SFTP); recommendation = SMB inbound с source-IP whitelist на время migration. Source: failed-robocopy инцидент 2026-05-23 18:08 (.tasks/iis-migration-to-ruvds.md Decisions log).

## [2026-05-24] ingest | concepts/books-ssh-access — SSH access audit на shared VDS pre-cutover Фазы 3 tenant-split. Retained keys table (1 key, vitya core dev), removed cosmetic dead root key, sshd hardening verified via `sshd -T` (not raw config), fail2ban active 2670 failed/37 banned, only vitya@94.19.247.14 в access log last 7 days. Source: .tasks/books-ssh-audit-shared-vds.md.

## [2026-05-24] ingest | RUVDS IIS migration + backup pipeline — entities/ruvds-iis-host (NEW, 80.64.31.36 Win Server 2025 Core, 25 SNI bindings, 2/24 hostnames DNS-flipped) + sources/iis-migration-to-ruvds-2026-05-23 (NEW, SSH/scp pivot после SMB-block by home-ISP) + sources/ruvds-backup-daily-kreknin-2026-05-24 (NEW, rclone+SFTP SYSTEM task daily 04:30) + concepts/traefik-acme-json-to-iis-cert-import (NEW, PFX+SNI recipe) + UPDATE concepts/windows-server-2025-core-bootstrap (SMB deprecate, HTTP middlebox warning, HTTP/2 note, backup-strategy + cert-import закрыты) + UPDATE entities/windows-recovery-host (IIS partial-cutover state, imgproxy SPOF carve-out) + UPDATE overview (RUVDS line). Sources: .tasks/iis-migration-to-ruvds.md, .tasks/ruvds-backup-daily-kreknin.md.

## [2026-05-28] ingest | vds-kzntsv DHCP outage postmortem — concepts/vds-kzntsv-dhcp-outage-2026-05-28 (NEW, симптомокартина + диагностический алгоритм + recovery runbook + RCA) + sources/vds-kzntsv-incident-2026-05-28 (NEW, timeline 05:25 backup OK → 08:15 detect → 08:43 statics fix → 08:50 disk GC; ticket text) + UPDATE entities/vds-kzntsv (Доступ §+subnet/gw/hypervisor/DNS resolvers; pass-store вместо .common/secrets; Known issues §NEW with 2026-05-28 incident; Open issues bump GC priority + iputils-ping note) + UPDATE concepts/rusonyx-vps-onboarding-quirks (quirk #9 NEW — gw в /18 надсети + recovery commands). Live session, no raw source ingested.

## [2026-05-28] update | vds-kzntsv DHCP outage post-resolution — после reset хостером в 13:52 MSK выяснилось что root cause — конфликт двух сетевых стеков (netplan+networkd поверх ожидаемого provider's ifupdown). Их `start/ipadd` ожидает чистый ifupdown, не мог auto-recover при разрыве DHCP binding. Resolution: mask netplan+systemd-networkd, reboot, provider положил `/etc/network/interfaces.d/ifcfg-eth0` с /18 netmask. UPDATE concepts/vds-kzntsv-dhcp-outage-2026-05-28 (revised RCA + permanent-fix § + anti-pattern + revised lessons-learned) + UPDATE sources/vds-kzntsv-incident-2026-05-28 (timeline до 14:00 + final config) + UPDATE entities/vds-kzntsv (mask /18, ifupdown stack, kernel cmdline net.ifnames=0) + UPDATE concepts/rusonyx-vps-onboarding-quirks (quirk #9 переписан про /18, quirk #10 NEW про ifupdown vs netplan stack). Memory `vds-kzntsv-rusonyx-network-recovery` переписан с новыми фактами.

## [2026-05-29] update | ES destructive-delete RECURRENCE — true root cause найден, диагноз сменился. UPDATE concepts/es-destructive-delete-incident-2026-05-26 (correction-блок + Hypothesis помечена ОПРОВЕРГНУТА + новая секция «Рецидив 2026-05-29 — true root cause»: ransom-бот через открытый `0.0.0.0:9200` мимо traefik+basicAuth, ES 7.10 free без auth; `read_me`=BTC-выкуп; снос by-name мимо Control #1; accessLog пуст т.к. бот шёл прямо в :9200; firewalld bypass docker-publish; Control #3 = убрать публикацию host-порта via Portainer PUT stack 33; restore из daily-2026-05-25; exposure-audit таблица — mongo/books-db/bookva-db/minio/bookva-minio тоже exposed но credentialed). bookva не пострадал (bookva-es порт не публикует). Live incident response session.

## [2026-06-05] ingest | NL VDS 3x-UI node + Reality PQ×dest root-cause
- new entities/nl-vds-3xui.md (213.176.64.253, Ubuntu 24.04, 3x-UI 3.2.7 / Xray 26.6.1); creds -> pass nl-vds-3xui/full-env
- new concepts/reality-pq-mldsa65-dest-incompatibility.md (root cause: ML-DSA-65 PQ ClientHello X25519MLKEM768 + Akamai dest www.intel.com -> HRR -> handshake fail; fix = PQ-capable dest e.g. www.microsoft.com, verified via isolation matrix)
- index.md updated (entity + concept). Fix NOT applied — awaiting user command.

## [2026-06-05] ingest | NL VDS 3x-UI session — honest final state + lessons
- NEW sources/nl-vds-3xui-setup-2026-06-05.md (chronicle: Reality PQ fix, port 443→2053, mtg MTProto, SOCKS5, friend-client instr; HONEST outcome — у реальных клиентов из РФ работает только plain VLESS 32030)
- NEW concepts/proxy-debugging-test-the-real-client.md (anti-pattern: свои curl/standalone-тесты ≠ боевой клиент; overclaim «РКН режет 443» / MSS-clamp по MTU-догадке сломал коннект)
- REWROTE entities/nl-vds-3xui.md — убраны ложные «Reality verified/fixed», «mtg неотличим»; честная таблица статусов (32030 🟢, Reality 2053 / MTProto 8443 / SOCKS 47020 🔴 у клиентов); MSS-clamp снят
- UPDATE concepts/reality-pq-mldsa65-dest-incompatibility.md — caveat «снятие PQ ≠ рабочий Reality у GUI-клиентов» + source link
- index.md updated (2 new pages). Креды/ссылки — pass nl-vds-3xui/full-env.

## [2026-06-06] decision | nl-vds-3xui: +3 classic Shadowsocks inbounds (ports 32031/32/33) for Outline-app, per-key revocable; protocol e2e-tested OK, RF reachability unverified (SS DPI-blocked in RF); creds in pass; discovered undocumented VLESS:13027.
