Reuses `cmd/internal/bootstrap` for env/auth and the root `onlyoffice` library for all API calls. UI logic in `cmd/office/ui/`; preview/formatting in `cmd/office/preview/`; list loaders in `cmd/office/fetch/`.
   - **List table (`DataTable`)** — `cmd/office/ui/table*.go`. Column layout policies live in `cmd/office/model/table_layout.go` (`TableFlexLayoutFor`); cell rendering uses the bubbles/table inline pattern in `table_render.go` (`renderTableCell`, `padANSIWidth`). See `.cursor/skills/office-tui-table/SKILL.md` before changing center-pane tables.
 - **Shared bootstrap — `cmd/internal/bootstrap/`.** `LoadEnv()` + `NewClient(ctx)` extracted from `oo`; both binaries import it.
-- **Applications sync — `cmd/oo/applications/`.** README→CRM bridge, CV-specific; kept under `cmd/oo/` so it's clear it's internal to the binary, not a library feature.
+- **Personal ops tooling** (disk inventory, dossier→CRM sync, SearXNG) lives in private [`eSlider/oo-workspace`](https://git.produktor.io/eSlider/oo-workspace) (`oow`), not in this public tree.

-### Job applications → CRM (`applications sync`)
-
-**Problem:** You keep CVs in a folder tree (`applications/2026/Acme/README.md`)

-re-typing.

-**Dry-run first** (default — prints what would happen, writes nothing):

-oo applications sync --path ./applications/2026 --verbose
-```
-
-**Apply** when the preview looks right:
-
-```bash
-oo applications sync --path ./applications/2026 --apply --verbose
-```
-
-Each dossier `README.md` is parsed for company, role, email, phone, LinkedIn, etc.
-Discovery walks `--path` and **skips** junk trees (`node_modules`, `tools`, `.venv`,
-`pdfs`, …). Only folders that look like CV application slugs (`source-NNN-…`, or
-long hyphenated dossiers) are synced — not npm package READMEs.
-
-The sync creates or finds contacts, opens a deal, adds members, and appends a
-history note. Re-running is safe: duplicate members and duplicate deal titles
-are skipped when already present.
-
-**After a large sync**, run CRM cleanup to collapse duplicates introduced by
-repeated runs or manual edits:

-```bash
-oo applications sync --path ./applications/2026 --apply
-oo crm cleanup -o json

+# CRM associations (company ↔ person ↔ deal ↔ project ↔ invoice ↔ mail)
+
+Operational rules for the `oo` CLI and this library. Business SSOT remains
+OnlyOffice Workspace CRM + Projects.
+
+## Canonical graph
+
+One **legal company** owns the relationship. Do not invent a second “bill-to”
+company just for PDF layout.
+
+```text
+Company
+├── Person (buyer contact)          oo persons create --company-id
+├── Opportunity / Deal              oo opportunities … ; member-add company + person
+├── Project (hub)                   oo projects … ; contacts add company + person
+│     └── Epic + subtasks
+└── Invoice (Draft → …)             oo invoices create --contact COMPANY --opportunity DEAL
+      └── PDF file                  oo invoices pdf ID
+            └── Mail draft          oo mails draft-invoice --invoice ID --to …
+```
+
+| 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
+```
