tasks(iis-migration-to-ruvds): pause после failed-robocopy + ingest SMB-default finding

Temp admin (2026-05-23 09:37-18:08) начал импл iis-migration-to-ruvds,
не закончил bootstrap, упал на UNC robocopy (exit 16) и dropped tree dirty.

Session recovery:
- secrets leak fix: `.secrets/ruvds-iis.env` → `pass show ruvds-iis/full-env`
  (etap-2 discipline restored). `.secrets/` + `*.env` + `*-log.txt` + `*-size.txt`
  added to `.gitignore` чтобы не повторилось.
- root cause зафиксирован: TCP/445 closed по дефолту на fresh Win Server 2025
  Core + SMB share не создан → UNC robocopy не работает без RUVDS bootstrap.
- new concept `windows-server-2025-core-bootstrap.md` — default-blockers
  table + transfer-методов матрица (RDP-redirect / SMB / WinRM / SFTP) +
  bootstrap-чеклист 12 шагов. Recommendation = SMB inbound с source-IP
  whitelist.
- task ⚪ → 🟡 paused с concrete next-step (capacity audit, transfer-method
  confirm, RUVDS bootstrap, backup source, recreate IIS sites + conn-string
  swap, pilot kupimknigi + DNS swap).
- Open question raised: source 11 sites сумма vs RUVDS 30 GB HDD — capacity
  blocker possible (snolla одна 8.66 GB).

Не push'нуто — ждёт user grant per project-discipline Rule 4.

 ## Migration approach
 
-1. **RDP-first setup** (RUVDS):
-   - Verify .NET Framework 4.8 installed (`Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\'`)
-   - Verify IIS 10 installed (`Get-WindowsFeature Web-Server`)
-   - Install URL Rewrite 2.1 (download + Server Manager cmd)
-   - Configure firewall: allow 80/443 inbound
-   - Test external MSSQL connection to VDS (89.253.255.94:1433)
-   - Test external MinIO connection to VDS (minio.kzntsv.site:443)
+1. **RDP-first setup** (RUVDS) — см. `concepts/windows-server-2025-core-bootstrap.md` §Bootstrap-чеклист:
+   - Install IIS (`Install-WindowsFeature Web-Server -IncludeAllSubFeature -IncludeManagementTools`)
+   - Verify .NET Framework 4.8 (Release ≥ 528040)
+   - Install URL Rewrite 2.1
+   - Open FW 80/443
+   - Test external MSSQL connection to VDS (`mssql.kzntsv.site:1433`)
+   - Test external MinIO connection (если CMS pipeline переезжает — см. caveat §MinIO ниже)
 
-2. **Backup source** (windows-recovery-host):
-   - Export IIS configuration: `%systemroot%\system32\inetsrv\appcmd.exe list site -config > sites-backup.txt`
+2. **Open SMB inbound на время migration** (см. transfer-методов матрица — это recommended choice):
+   - `Set-NetFirewallRule -DisplayGroup "File and Printer Sharing" -Enabled True`
+   - `New-NetFirewallRule -DisplayName "SMB-from-source" -Direction Inbound -Protocol TCP -LocalPort 445 -RemoteAddress <source-public-ip> -Action Allow`
+   - `New-Item -ItemType Directory -Path C:\sites -Force`
+   - `New-SmbShare -Name sites -Path C:\sites -FullAccess Administrator`
+
+3. **Backup source** (windows-recovery-host):
+   - Export IIS configuration: `appcmd list site -config > sites-backup.txt`
    - Export applicationHost.config: `C:\Windows\System32\inetsrv\config\applicationHost.config`
-   - Backup inetpub\wwwroot\ (11 sites, ~100MB-1GB each)
+   - Backup inetpub\wwwroot\ (11 sites, ~8.66 GB на snolla одной, итого предположительно ~30-50 GB total)
    - Document Web.config connection strings (MSSQL/MinIO endpoints)
 
-3. **Deploy to target** (RUVDS):
-   - Create IIS sites matching source structure
-   - Copy site contents (RDP drive mount or WinRM copy)
-   - Update Web.config connection strings → point to VDS MSSQL/MinIO
-   - Import SSL certificates (traefik LE certs) or setup new LE on IIS
+4. **Deploy to target** (RUVDS) — через SMB robocopy:
+   - `net use \\<ruvds-ip>\sites /user:Administrator <pass-from-pass>`
+   - `robocopy C:\sites\<site> \\<ruvds-ip>\sites\<site> *.* /S /E /DCOPY:DA /COPY:DAT /Z /MT:8 /R:2 /W:5` per site
+   - Recreate sites через `appcmd add site` или `New-IISSite`, копировать bindings
+   - Update Web.config connection strings → `Data Source=mssql.kzntsv.site,1433;TrustServerCertificate=True` (matches `[mssql-vds-migration]` pattern)
+   - Import SSL certificates (traefik LE certs) или setup new LE через `win-acme` (wacs.exe)
 
-4. **Pilot on kupimknigi.spb.ru**:
-   - DNS pointing test (local hosts file or temporary DNS)
+5. **Pilot on kupimknigi.spb.ru** (low-traffic):
+   - DNS pointing test (local hosts file или temporary DNS)
    - Smoke test: homepage + admin + database connectivity
-   - 24h soak — monitor stability
-   - If OK → proceed with remaining 10 sites
+   - 24h soak — monitor stability (включая memory pressure — 2GB tight)
+   - Если OK → proceed с remaining 10 sites
 
-5. **DNS swap cutover**:
-   - Update DNS A records → RUVDS IP
-   - Monitor traefik logs on windows-recovery-host (should see 0 traffic)
-   - Keep windows-recovery-host warm for 1 week rollback window
+6. **DNS swap cutover**:
+   - Update DNS A records → RUVDS IP (`80.64.31.36`)
+   - Monitor traefik logs на windows-recovery-host (должно увидеть 0 traffic)
+   - Keep windows-recovery-host warm для 1 week rollback window
+   - **Cleanup на RUVDS:** `Remove-SmbShare -Name sites` + `Remove-NetFirewallRule -DisplayName "SMB-from-source"`
 
-## Acceptance criteria
+## Decisions log
 
-- [ ] RUVDS IIS serving all 11 sites
-- [ ] All sites functional (no 500 errors, DB connectivity OK)
-- [ ] DNS pointed to RUVDS
-- [ ] 24h stability soak passed
-- [ ] Rollback plan documented (revert DNS to home IP)
-- [ ] windows-recovery-host VM shutdown / saved-state
+- **2026-05-23 09:37 (admin attempt):** RDP creds сохранены в `.secrets/ruvds-iis.env` (plaintext, в repo tree → нарушение etap-2 secrets-discipline, ретроспективно зафикшено в текущей сессии: → `pass show ruvds-iis/full-env`).
+- **2026-05-23 18:01 (admin attempt):** замерен размер `C:\sites\snolla\` = 8871 MB ≈ 8.66 GB. Источник для capacity planning (snolla alone 8.66 GB → 11 sites суммарно может быть 30-50 GB → 30 GB HDD на RUVDS **tight**, потенциальный capacity blocker, см. Open questions).
+- **2026-05-23 18:08 (admin attempt):** robocopy `C:\sites\snolla\` → `\\80.64.31.36\sites\snolla\` упал exit 16 «сетевой путь не найден». Root cause (post-mortem из текущей сессии): TCP/445 closed по дефолту на Win Server 2025 Core + SMB share `sites` не создан. UNC robocopy как первый transfer-метод **не работает** на fresh Core без подготовки RUVDS-стороны.
+- **2026-05-23 (current session) recommendation:** SMB inbound с source-IP whitelist — самый быстрый transfer для 11 sites × ~1 GB, native robocopy /Z поддерживает interrupt-resume, FW rule убирается после cutover. Полная матрица альтернатив (RDP-redirect / WinRM / SFTP) в `concepts/windows-server-2025-core-bootstrap.md` §Transfer-методов.
+- **MinIO pipeline caveat (из `[iis-cutover-to-vds-services]` 2026-05-22):** CMS image pipeline остаётся целиком на windows-recovery-host из-за hardcoded URL в `MoreThenCms.Modules.Imgproxy.dll`. RUVDS-IIS будет coupled к windows-host imgproxy через DNS `imgproxy.kzntsv.site` — то есть RUVDS IIS вызывает server-side GET на windows-host'овский imgproxy. Это **не убирает SPOF домашней машины** для image-rendering pipeline. Если windows-host умрёт, image-URLs broken. Open question для post-migration phase: decompile DLL или Option B (local nginx-relay).
 
 ## Open questions
 
-- [ ] **RUVDS public IP** — assigned yet? Need for DNS A records.
-- [ ] **SSL strategy** — use existing traefik LE certs (export?) or setup new LE on IIS?
-- [ ] **Traefik на RUVDS?** — IIS-only (port 80/443 direct) или traefik reverse proxy again?
-- [ ] **Backup strategy for RUVDS IIS** — VDS snapshot? IIS native backup?
+- [ ] **RUVDS disk capacity** — 30 GB HDD vs estimated 30-50 GB total sites. Нужен audit `Get-ChildItem C:\sites -Directory | %{[PSCustomObject]@{Name=$_.Name; SizeGB=(Get-ChildItem $_.FullName -Recurse | Measure-Object -Property Length -Sum).Sum / 1GB}}` на source перед transfer'ом. Если >25 GB — нужен upgrade RUVDS plan (или selective transfer без cache/logs/temp dirs).
+- [ ] **SSL strategy** — use existing traefik LE certs (export?) или setup new LE на IIS via `win-acme`? Recommendation: `win-acme` — standalone-friendly на Core, не зависит от traefik export-ритуала.
+- [ ] **Traefik на RUVDS?** — IIS-only (port 80/443 direct) или traefik reverse proxy again? Recommendation: IIS-only для 11 sites, traefik overkill; ставить traefik только если будут не-IIS workloads на RUVDS.
+- [ ] **Backup strategy для RUVDS IIS** — расширить `vds-backup-rsync-kreknin` cron на RUVDS как третий source? VDS snapshot? IIS native backup (`Backup-WebConfiguration`)? Решение откладывается до после успешного cutover.
+- [ ] **Image-pipeline SPOF (post-cutover):** windows-host imgproxy остаётся single-point — Option B/D из `[iis-cutover-to-vds-services]` MinIO-phase. Решение откладывается до после успешного cutover.
+
+## Completed steps
+
+- [x] **2026-05-22:** vendor research (`windows-hosting-vendor-research` 🟢) — RUVDS selected.
+- [x] **2026-05-23 09:37:** RUVDS purchased + RDP creds saved. **Note:** creds сначала жили в `.secrets/ruvds-iis.env` plaintext (нарушение etap-2 discipline); ретроспективно вынесены в `pass show ruvds-iis/full-env` 2026-05-23 в session-recovery.
+- [x] **2026-05-23 18:01:** source size probe — `C:\sites\snolla\` = 8.66 GB.
+- [x] **2026-05-23 18:08:** failed-robocopy attempt → root-cause analysis → finding закреплён в `[[../.wiki/concepts/windows-server-2025-core-bootstrap]]`.
 
 ## Notes
 
-- **Windows Server 2025 Core** = GUI-less, PowerShell-only management. No Server Manager desktop.
-- **2GB RAM constraint** — IIS + 11 sites = tight. Monitor memory after pilot.
-- **Migration is transitional** — long-term snolla-on-node makes IIS obsolete. Don't over-engineer.
+- **Windows Server 2025 Core** = GUI-less, PowerShell-only management. No Server Manager desktop. Drag-n-drop в RDP не работает без `mstsc /admin` Local Drives redirect.
+- **2GB RAM constraint** — IIS + 11 sites = tight. Monitor memory после pilot. Возможно нужен per-pool `RecyclingPeriodicRestartMemory 200MB`.
+- **Migration is transitional** — long-term snolla-on-node makes IIS obsolete. Don't over-engineer (не ставить Prometheus, не writing custom monitoring).
+- **Image-pipeline caveat:** даже после RUVDS cutover, windows-host остаётся SPOF для image-rendering (см. Decisions log §MinIO caveat).
