-
-| Layer | CLI | Must link |
-|-------|-----|-----------|
-| Company | `oo companies create` | website, email, phone, **one** Billing address |
-| Person | `oo persons create --company-id` / `oo persons update ID` | job title; never encode employer in `lastName`; **update uses JSON** (form PUT ignores `companyId`/`about`) |
-| Deal | `oo opportunities create` + `member-add` | company **and** person as members |
-| Project | `oo projects create` + `contacts add` | same company + person |
-| Invoice | `oo invoices create --contact COMPANY --opportunity DEAL` | `entityId` at **create** |
-| Mail | `oo mails draft-invoice` | attach current PDF; **do not send** until confirmed |
-
-UI checks (same company card):
-
-- `#contacts` → person  
-- `#deals` → opportunity  
-- `#projects` → hub project  
-- `#invoices` on the **deal** → invoice (needs `entity`)  
-- `#files` → preferably **one** current invoice PDF
-
-**Project Team ≠ Project Contacts.** Team = portal users. CRM people/companies
-show under the project **Contacts** tab (`oo projects contacts list`).
-
-## Hard rules
-
-1. **One company per legal entity.** Duplicate “bill-to” contacts empty Deals /
-   Projects / Contacts tabs and break merge. Prefer
-   `oo contacts merge FROM INTO` (keeps `INTO`) or `oo companies dedupe`.
-2. **Link invoice → deal at create.**  
-   `POST /crm/invoice` with `entityId` + `entityType: 0` (Opportunity).  
-   `oo invoices update … --opportunity` often returns **400**
-   (“Value does not fall within the expected range”). If the link is missing,
-   delete the Draft and recreate with `--opportunity`.
-3. **Bill To = company id**, not a throwaway contact. Person stays under the
-   company (`companyId`). Optional `consigneeId` for Empfänger when the portal
-   template prints it.
-4. **Stay Draft until mail is ready.** Billed (`status id=2`) is **not editable**
-   via content PUT. Going Billed → Draft via `…/crm/invoice/status/1` usually
-   **does not work** — delete + recreate Draft instead.
-5. **Do not regenerate PDF in a loop** without cleanup. Each
-   `GET …/crm/invoice/{id}/pdf` attaches a new file to the company (and often
-   the deal). Keep `invoice.fileID`; delete older PDFs with
-   `oo invoices pdf-cleanup ID` / Documents `fileops/delete`.
-
-## Invoice PDF quirks
-
-| Symptom | Workaround |
-|---------|------------|
-| Cached / stale PDF | Touch invoice (Draft PUT that clears `fileID`), then `GET …/pdf` — `oo invoices pdf ID --force` |
-| Billing address missing on **new** PDFs | Temporary multiline `companyName` (`Line1\nLine2\n…`) on the **canonical** company → force PDF → restore clean name. Cached `fileID` keeps the multiline Bill To. |
-| Separate bill-to company for newlines | **Forbidden** — merge back to the real company |
-| Invoice **number** won’t change on PUT | Delete Draft and recreate with the desired number |
-| Notizen / Bedingungen spacing | Leading `\n` and blank lines only — no HTML (tags print literally) |
-| Issuer street lines | Organisation profile address (`street` with `\n`), not only terms |
-
-Status ids commonly used: `1` Draft, `2` Billed, `3` Rejected, `4` Paid.
-
-## Mail quirks
-
-| Symptom | Workaround |
-|---------|------------|
-| Signature / body doubles chat URL | Put chat in **one** place only. UI drafts: signature. API send: body (API **does not** append signature). |
-| Signature / body cuts URL at `#` | Plain text URLs — avoid `<a href="…#…">` (or encode `#` as `%23` in href) |
-| German letter spacing | Blank `<p>&nbsp;</p>` between blocks (`MailHTMLWithBlankParagraphs`) |
-| Send | `PUT /api/2.0/mail/messages/send.json` with `id/from/to/subject/body`; omit empty `cc`/`bcc`. Never auto-send; draft only until the human confirms |
-
-Prefer OnlyOffice Mail (`/addons/mail/#drafts`) for invoice delivery until confirmed.
-
-## Project / task quirks
-
-- Hub title: `CC | Company` (e.g. `DE | Acme GmbH`).
-- Streams = epics/tasks under the hub, not a third title segment (unless the
-  project itself is a named delivery stream).
-- Closing a **subtask**:  
-  `PUT /api/2.0/project/task/{epicId}/{subtaskId}/status` with `status=2`.  
-  `oo tasks update SUBTASK -s closed` returns **404** for subtasks.
-- After deleting a CRM contact, `GET /project/contact/{deletedId}` may still
-  return projects (ghost). Official project contact list should only show live
-  ids; unlink may 400 if the contact is gone.
-
-## Merge / cleanup cheat sheet
-
-```bash
-# Keep the preferred company (INTO), drop the duplicate (FROM)
-oo contacts merge FROM_ID INTO_ID
-
-# Or by normalized name (careful — whole CRM)
-oo companies dedupe
-
-# Invoice ↔ deal must exist at create
-oo invoices create --number P-YYYY-NN --contact COMPANY_ID --item ITEM_ID \
-  --price 300 --opportunity DEAL_ID --language de-DE …
-
-# Fresh PDF + prune older PDFs on company/deal
-oo invoices pdf INVOICE_ID --force
-oo invoices pdf-cleanup INVOICE_ID
-
-# Mail draft (no send)
-oo mails draft-invoice --invoice INVOICE_ID --to billing@example.com
-```

-# rclone WebDAV mount — OnlyOffice Documents как файловая ФС
-
-`deploy/docker-compose.rclone-webdav.yml` монтирует WebDAV-дерево OnlyOffice
-через `rclone`. Не systemd, только compose. Контейнер — `rclone-webdav`.
-
-## Что монтируется
-
-- Источник — сайдкар `oo-webdav` (`ghcr.io/eslider/oo-webdav`).
-- Адрес — `http://172.17.0.1:8098`, префикс `/webdav`.
-- Basic-auth — креды портала OnlyOffice (те же, что у `oo`).
-- Корень — `Dokumente der Projekte/…` (папка `Fibu EDL` внутри).
-
-## Конфиг
-
-- Образ — `rclone/rclone`.
-- Remote — on-the-fly `:webdav:` плюс флаги `--webdav-url`, `--webdav-user`,
-  `--webdav-pass`.
-- На старте контейнер пишет `/config/rclone/rclone.conf` (`[webdav]`), чтобы
-  `rclone ls webdav:` внутри контейнера работал без флагов.
-- `ONLYOFFICE_PASSWORD` — plain; rclone сам зовёт `rclone obscure`.
-- Флаги mount: `--vfs-cache-mode writes`, `--cache-dir /cache`,
-  `--dir-cache-time 1m`, `--allow-other`, `--allow-non-empty`.
-- FUSE: `cap_add: [SYS_ADMIN]`, `devices: [/dev/fuse]`,
-  `security_opt: apparmor:unconfined`.
-- Тома: `onlyoffice-mnt` → `/mnt/onlyoffice`, `rclone-cache` → `/cache`.

-## Ограничения
-
-- Нужен FUSE: `SYS_ADMIN` + `/dev/fuse`. На хосте без FUSE не поедет.
-- Сайдкар слушает docker-bridge `172.17.0.1:8098`, публично не выставлен.
-  Только localhost/локальные контейнеры.
-- Запись идёт через VFS write-back (по умолчанию ~5s). Перед проверкой
-  «файл на сервере» опрашивать сервер, не доверять сразу после `write`.
-- `rmdir` через монтирование НЕ доходит до `oo-webdav` (пустой каталог
-  остаётся на сервере). Удалять каталоги напрямую:
-  `rclone rmdir webdav:<path>` или `rclone purge webdav:<path>`.
-- VFS-кэш растёт в томе `rclone-cache`; ограничить `--vfs-cache-max-size`.
-- Блокировок между редактором OnlyOffice и монтированием нет. Не редактировать
-  один и тот же файл одновременно.
-- Данные не шифруются на диске хоста в `rclone-cache` (том Docker).
