+description: >-
+  Build and fix Bubble Tea list tables in cmd/office (DataTable, column layout,
+  lipgloss cell rendering, pane width). Use when changing office center-pane
+  tables, column widths, ANSI styling, or list toolbar alignment.
+---
+# office TUI table (`cmd/office/ui`)
+
+## Architecture
+
+| Piece | File | Role |
+|-------|------|------|
+| `DataTable` | `table.go` | cursor, sort, viewport, header/row render |
+| Column layout | `table_layout.go` | flex vs horizontal-scroll policies |
+| Flex policy | `model/table_layout.go` | per-subject flex column key + min width |
+| Cell render | `table_render.go` | bubbles/table pattern + ANSI-safe padding |
+| Subject row style | `table_projects.go` | optional per-subject cell styles |
+| Pane sizing | `scroll.go` | `paneContentWidth`, `paneLipglossWidth` |
+| Scrollbar pad | `scrollbar.go` | `padANSIWidth` for styled lines |
+
+## Layout policies
+
+1. **Flex (all columns visible)** — register in `model.TableFlexLayoutFor`:
+   - fixed columns keep `TableColumn.Width`
+   - one `FlexColumnKey` (e.g. `title`, `email`) absorbs remainder
+   - `layoutFlexTable` shrinks fixed cols down to `minFixedColumnWidth` before flex min
+
+2. **Scrolling (default)** — `layoutScrollingTable`:
+   - horizontal `colScroll`; subset of columns visible
+   - `distributeColumnWidths` fills pane width
+
+Add a new flex subject: one entry in `TableFlexLayoutFor` only — do **not** copy `layoutProjectTable`/`layoutUserTable` per subject.
+
+## Cell rendering (required pattern)
+
+Never `style.Width(w).Padding(0,1).Render(text)` on styled cells — padding doubles display width and breaks `JoinHorizontal`.
+
+Use `renderTableCell` from `table_render.go` (matches `charmbracelet/bubbles/table`):
+
+```go
+renderTableCell(outerStyle, plainText, columnWidth)
+```
+
+- truncate **plain** text with `runewidth.Truncate` inside `renderTableCell`
+- inner box: `Width(innerW).Inline(true)` where `innerW = width - outer.GetHorizontalFrameSize()`
+- outer style carries padding, background, foreground
+
+## ANSI rules
+
+- **Never** `runewidth.Truncate` / `padDisplayWidth` on strings that already contain lipgloss ANSI codes — corrupts escapes and shows garbage like lone `ID`.
+- Use `padANSIWidth` (`charmbracelet/x/ansi`) for styled lines (headers, toolbar, scrollbar rows).
+- Do not wrap an already full-width styled header in another `lipgloss.Width()` — pad once.
+
+## Pane width
+
+Lipgloss bordered panes render **2 cells wider** than `Style.Width`:
+
+- `paneLipglossWidth(rendered) = rendered - 2` for `.Width()` on pane style
+- `paneContentWidth(rendered) = rendered - 4` for table/viewport inner size (border + padding)
+
+Pass `paneContentWidth(pw.List)` to `DataTable.SetSize` and list toolbar.
+
+## Tests to add when touching tables
+
+- `layoutFlexTable` width sum equals pane width
+- `TestProjectTableHeaderFitsPaneWidth` / per-line width at 68, 40, 30
+- `TestPadANSIWidthPreservesStyledLine`
+- `TestThreePaneRenderedWidthMatchesTerminal` top border + table lines ≤ inner width
+
+## Anti-patterns
+
+- Per-subject duplicate layout files (`table_foo.go` with copy-pasted shrink loops)
+- Skipping truncation on selected rows (causes multi-line rows in viewport)
+- Using `bubbles/table` widget directly — office needs column cursor, multi-select, subject-specific row styles

-Canonical Go client for OnlyOffice Workspace (Projects + Calendar + CRM) and the `oo-cli` command.
+Canonical Go client for OnlyOffice Workspace (Projects + Calendar + CRM) and the `oo` command.
 
 ## Topology
 
-- **Library (root package `onlyoffice`)** — `onlyoffice.go`, `httpx.go`, `calendar.go`, `crm.go`, `tasks_extra.go`, `files.go`. Pure stdlib + `google/go-querystring`; no UI, no dotenv.
+- **Library — flat package `onlyoffice` at repo root.** Split by *domain file*, not by subpackage, so every call site reads `c.XxxYyy()` against a single `*Client`. Files:
-- **CLI (`cmd/oo-cli` + `internal/cli`)** — Cobra wrapper that loads `.env` via `godotenv` at startup. CLI-only deps (`spf13/cobra`, `joho/godotenv`) must stay out of the library surface.
+  - `client.go` — `Client`, `Credentials`, `Defaults`, env helpers, `NewClient`.
-- **Applications sync (`internal/applications`)** — README/CRM bridge, consumes the library.
+  - `request.go` — `Request`, `Query`, `Time`, `Token`, `MetaResponse`, `Permissions`.
+  - `auth.go` — `Authenticate`, `AuthenticateContext`, `InvalidateToken`, `Auth`, token lifecycle.
+  - `http.go` — transport + DRY response decoders (`ResponseArray`/`ResponseObject`/`postFormObject`/`putFormObject`/`deleteObject`).
+  - `projects.go`, `tasks.go`, `users.go`, `calendar.go`, `crm.go`, `files.go`, `mails.go`, `invoices.go` — typed / untyped domain methods. **`files.go`** — CRM opportunity upload plus **project/task Documents**. **`mails.go`** — OnlyOffice Workspace Mail. **`invoices.go`** — CRM invoices, PDF regen/cleanup, status. Association rules: [`docs/crm-associations.md`](docs/crm-associations.md).
+  - Pure stdlib + `google/go-querystring`; no UI, no dotenv.
+- **CLI — `cmd/oo/` as `package main`.** Cobra wrapper that loads `.env` via `godotenv` at startup. **Subject-based command tree** mirroring [`tea`](https://gitea.com/gitea/tea):
+  - `main.go` — entry point (docstring lists the command tree).
+  - `common.go` — `rootCmd`, `newOO`, `printTable`/`printObject`, `--output table|json` flag.
+  - `calendar.go`, `projects.go`, `projects_files.go`, `tasks.go`, `tasks_files.go`, `users.go`, `contacts.go`, `opportunities.go`, `cases.go`, `crm_tasks.go`, `mails.go`, `invoices.go` — one file per subject (or per subject facet), each registers in `init()`.
+  - CLI-only deps (`spf13/cobra`, `joho/godotenv`) stay out of the library.
+- **TUI — `cmd/office/` as `package main`.** Bubble Tea three-pane browser (module tree, selectable list, markdown preview). 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.
+- **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.
 
 ## Rules
 
 - Library must never call `godotenv.Load()` — the CLI does that.
 - New endpoints go into the library first; CLI commands are thin wrappers.
+- Prefer `ResponseObject` / `postFormObject` / `putFormObject` / `deleteObject` over hand-rolled `json.Unmarshal(responseField(...))` blocks — they exist for DRY, use them.
+- Domain split is by file, **not** by subpackage. Don't introduce `internal/` or `pkg/*` subpackages inside the library — it flattens the `*Client` call surface for a reason.
+- CLI commands follow **subject → verb** structure (`oo <subject> <verb>`), never `oo <verb>-<subject>`. Add new commands to the existing subject file if one fits; create a new `cmd/oo/<subject>.go` for a genuinely new domain.
+- **Documents for agents:** prefer Markdown in git; OnlyOffice UI is weak for `.md`/`.txt`. Use `oo docs put-md` (md→docx) and `oo docs put-txt` (txt→docx, preserves line breaks). `oo projects files dedupe PROJECT_ID` reports/removes duplicate stem|ext copies (`--apply`, `--cross`).
+- Every table output goes through `printTable(headers, rows)`; every single-object through `printObject(v)`. Do not `fmt.Println` rows ad-hoc or the `--output json` flag breaks for that command.
 - No secrets in the repo; use `.env` (gitignored). Commit `.env.example` only.
 - Follow SemVer on tags; this repo is tagged at GitHub under `git@github.com:eSlider/go-onlyoffice.git`.

+
 ## [Unreleased]
 
+## [0.7.0] — 2026-06-24
+
+### Added — `office` TUI
+
+- **Pane layout** — default **10% / 60% / 30%** split (nav / list / detail); drag vertical borders to resize; **Alt+1/2/3** still toggles panes.
+- **Filter mode** (`f`) — live filter on nav + list; right pane is the search query; **Esc** clears.
+- **Mail preview** — HTML bodies rendered colorized in the terminal (glamour); read-only scrollable document pane.
+- **Mail infinite scroll** — loads the next page automatically when the cursor nears the end of the list.
+- **Scrollbars** — vertical scrollbar on nav, list body, and detail preview when content exceeds the viewport.
+- **Calendar** — unified calendars + events leaf with **Type** column and date range (−7d … +30d).
+- **Tasks** — humanized status labels and relative deadlines in the list.
+- **Projects** — open/closed row colors; status toggle in the detail form; **Save** sends `responsibleId` and status via `UpdateProjectStatus`.
+
+### Changed — `office` TUI
+
+- Flattened navigation: **Projects**, **Tasks**, **By project**, **Calendar**, **CRM**, **Mail**, **Users** (removed Browse; Calendar no longer splits Calendars/Events).
+- Middle pane truncates overflowing cells with `…`; full text on the cursor or Space-selected row.
+- Detail form tab order: Title → Description → Status → Save → Delete.
+- **j/k** scrolls mail/file preview and read-only detail forms; mouse wheel scrolls detail when hovering the content area.
+
+### Added — library
+
+- `UpdateProjectStatus` — `PUT /api/2.0/project/{id}/status` for open/closed lifecycle.
+
+## [0.5.1] — 2026-06-24
+
+### Added — `office` TUI
+
+- **Alt+1 / Alt+2 / Alt+3** — show/hide left (nav), middle (table), and right (detail) panes.
+- Visible panes share **100% terminal width** evenly; pane content fills its column.
+- Tab focus skips hidden panes.
+
+### Changed — `office` TUI
+
+- Split detail pane: form/document top (~72%), CRUD action bar bottom.
+- Middle pane: multi-column table with sort, selection, and full-width columns.
+- Project list columns: ID, Title, Tasks (open/closed), Documents, Users.
+- Row selection auto-loads detail; files show document preview, entities show forms.
+
+## [0.6.0] - 2026-04-24
+
+### Added — library
+
+- **Project & task Documents API** in [`files.go`](files.go):
+  - `FileEntry`, `FolderEntry`, `ProjectFilesResponse` types.
+  - `GetProjectFiles`, `GetTaskFiles`, `GetFile`.
+  - `UploadProjectFile` — `POST /api/2.0/files/{folderId}/upload` into the
+    project's `projectFolder` (resolved via `GetProjectByID` or first folder
+    from `GetProjectFiles`).
+  - `AttachFilesToTask` — `POST .../project/task/{id}/files` with form
+    `files=<id>` (OnlyOffice expects **existing** file ids, not multipart).
+  - `UploadTaskFile` — uploads via `UploadProjectFile` using the task's
+    `projectOwner.id`, then attaches.
+  - `DetachTaskFile` — `DELETE .../files?fileid=`.
+  - `RenameFile` — `PUT /api/2.0/files/file/{id}.json` with JSON body.
+  - `DeleteFiles` — `PUT /api/2.0/files/fileops/delete.json` with `fileIds`.
+  - `DownloadFile` — `GetFile` then `GET` on `viewUrl` with `Authorization`.
+  - Helpers: `FileEntryNumericID`, `FileEntryTitle`, `SafeLocalFileName`.
+- **`putJSON`** on `*Client` in [`http.go`](http.go) for JSON PUT bodies.
+
+### Added — CLI
+
+- `oo projects files list|upload|download|rename|delete` — see
+  [`cmd/oo/projects_files.go`](cmd/oo/projects_files.go); `list` supports
+  `--folders`.
+- `oo tasks files list|upload|detach` — see [`cmd/oo/tasks_files.go`](cmd/oo/tasks_files.go).
+
+### Added — tests
+
+- [`files_integration_test.go`](files_integration_test.go) — live roundtrip
+  against OnlyOffice (same credential rules as `client_test.go`).
+- [`files_test.go`](files_test.go) + `testdata/*.json` — envelope decode unit
+  tests (no network).
+
+## [0.5.0] - 2026-04-24
+
+### Changed — CLI **BREAKING**
+
+- **Subject-based command tree** (`tea`-style). The flat `oo verb-noun`
+  layout is replaced with `oo <subject> <verb>`:
+
+  | Old | New |
+  |---|---|
+  | `oo cal-list` | `oo calendar list` |
+  | `oo cal-events` | `oo calendar events` |
+  | `oo cal-add` / `cal-delete` | `oo calendar add` / `calendar delete` |
+  | `oo task-list` | `oo tasks list` |
+  | `oo task-add` | `oo tasks create` |
+  | `oo task-update` | `oo tasks update` (deletion moved to `oo tasks delete`) |
+  | `oo subtask-add` | `oo tasks subtask add` |
+  | `oo crm-contacts` | `oo contacts list` (plus filtered `oo persons list` / `oo companies list`) |
+  | `oo crm-add-contact --company …` | `oo companies create --name …` |
+  | `oo crm-add-contact --person-first …` | `oo persons create --first …` |
+  | `oo crm-deals` | `oo opportunities list` |
+  | `oo crm-deals --stages` | `oo opportunities stages` |
+  | `oo crm-add-deal` | `oo opportunities create` |
+  | `oo crm-cases` | `oo cases list` |
+  | `oo applications-sync` | `oo applications sync` |
+
+- **New subjects**: `oo projects {list,get,milestones,create,update,delete}`,
+  `oo users {list,self}` (plus top-level `oo whoami`), `oo crm-tasks
+  {list,create,delete,categories}`, `oo cases {create,delete,member-add}`,
+  `oo contacts {get,info-add}`.
+
+- **Global `--output/-o` flag**: all list-like commands now support
+  `--output table` (default; tabwriter-aligned, truncated to 80 chars
+  per cell) and `--output json`. Nested `bidCurrency` flattened to its
+  `abbreviation` in the table view.
+
+- **Module aliases**: `oo calendar|cal`, `oo projects|prj`, `oo tasks|task`,
+  `oo persons|person`, `oo companies|company`, `oo opportunities|deals|deal`,
+  `oo cases|case`, `oo applications|apps`. `delete|rm` on every leaf that
+  removes things.
+
+### Added
+
+- `cmd/oo/common.go` — shared `printTable(headers, rows)` and
+  `printObject(v)` helpers that dispatch on the `--output` flag.
+- `cmd/oo/users.go` — exposes `oo users list`, `oo users self`, `oo whoami`
+  via the library's `GetUsers` + `SelfUserID`.
+- `cmd/oo/projects.go` — full CRUD for projects backed by `CreateProject`,
+  `UpdateProject`, `DeleteProject`, `GetProjectByID`, `GetProjectMilestones`.
+- `cmd/oo/crm_tasks.go` — dedicated `oo crm-tasks` subject (distinct from
+  project `oo tasks`).
+- `cmd/oo/contacts.go` — unified contacts/persons/companies with shared
+  list/filter implementation.
+
+### Changed — library (minor)
+
+- `newOO` in `cmd/oo/common.go` now calls `AuthenticateContext(cmd.Context())`
+  so CLI aborts propagate to the auth request.
+
+## [0.4.0] - 2026-04-24
+
+### Changed — project structure
+
+- **Library files reorganised by domain** (mechanical split; zero API surface
+  change). The former monolithic `onlyoffice.go` (687 LOC) is now split into:
+  - `client.go` — `Client`, `Credentials`, `Defaults`, env helpers, `NewClient`.
+  - `request.go` — `Request`, `Query`, `Time`, `Token`, `MetaResponse`,
+    `Permissions`, `requestBodyReader`.
+  - `auth.go` — `Authenticate`, `AuthenticateContext`, `InvalidateToken`,
+    `Auth`, `ensureToken`, `authHeader`, `tokenValid`.
+  - `http.go` — transport helpers and DRY response decoders
+    (`ResponseArray`, `ResponseObject`, `postFormObject`, `putFormObject`,
+    `deleteObject`, `unmarshalResponseObject`).
+  - `projects.go` — `Project`, `Projects`, `Milestone`, `ProjectOwner` +
+    `GetProjects` / `CreateProject` / `UpdateProject` / `DeleteProject` /
+    `GetProjectByID` / `GetProjectMilestones`.
+  - `tasks.go` — `Task`, `ProjectTaskStatus`, `TaskPriority`,
+    `ProjectGetTasksRequest` et al. **plus** the form-encoded helpers
+    formerly in `tasks_extra.go` (`ListTasks`, `AddTask`, `AddSubtask`,
+    `UpdateTaskStatus`, `DeleteTask`, `GetTaskByID`).
+  - `users.go` — `User`, `Contact`, `Group`, `GetUsers`, `SelfUserID`.
+  - `calendar.go`, `crm.go`, `files.go` — unchanged in scope, refactored
+    through the new DRY helpers.
+  - `httpx.go` → **renamed** `http.go`.
+  - `onlyoffice.go` and `tasks_extra.go` — **deleted** (content redistributed).
+
+### Changed — CLI **BREAKING**
+
+- **Binary renamed `oo-cli` → `oo`.** Install with
+  `go install github.com/eslider/go-onlyoffice/cmd/oo@latest`.
+- **Package path `cmd/oo-cli` → `cmd/oo`.** The old path is removed.
+- **`internal/cli` is gone.** Cobra commands now live directly under
+  `cmd/oo/` as `package main`, split by domain: `calendar.go`, `crm.go`,
+  `tasks.go`, `apps.go`, `common.go`. Rationale: cobra wiring is a CLI-only
+  concern and does not belong inside a `pkg-level internal/`.
+- **`internal/applications` → `cmd/oo/applications/`.** This is a
+  CV-specific CRM workflow — not a general OnlyOffice feature — and is only
+  consumed by the `oo` CLI. Keeping it under `cmd/oo/` prevents accidental
+  external adoption and makes the coupling explicit.
+- **`examples/applications/` removed.** It imported an internal package,
+  which was a policy smell. Remaining examples (`basic`, `calendar`, `crm`,
+  `subtasks`) use only the exported library surface.
+
+### Added
+
+- `(*Client).ResponseObject` — GET-and-decode-object counterpart to the
+  existing `ResponseArray`.
+- `(*Client).postFormObject` / `putFormObject` / `deleteObject` — eliminate
+  the ~15 identical "form request → `responseField` → `json.Unmarshal`"
+  blocks previously duplicated across `crm.go` / `tasks_extra.go` /
+  `calendar.go` / `files.go`.
+
+### Migration
+
+External library consumers: **no changes required**. The module path
+(`github.com/eslider/go-onlyoffice`), the `onlyoffice` package name, and
+every exported symbol are unchanged.
+
+CLI users: replace `oo-cli` with `oo` in scripts and CI. The command set
+and flags are identical.
+

-A ready-to-use Cobra CLI wrapping the library lives under `cmd/oo-cli`:
+A ready-to-use [Cobra](https://github.com/spf13/cobra) CLI wrapping the

-The CLI reads `.env` from CWD (godotenv is a CLI-only concern — the library
+### office (TUI)
-itself never loads dotfiles). See [`cmd/oo-cli/README.md`](cmd/oo-cli/) for
+
-the command reference.
+Terminal UI for browsing OnlyOffice Workspace — module tree (left), selectable
+lists (center), and markdown preview (right). Uses the same `.env` credentials
+as `oo`. Lives under [`cmd/office`](cmd/office/).
+
+```bash
+go install github.com/eslider/go-onlyoffice/cmd/office@latest
+office
+```
+
+| Key | Action |
+|---|---|
+| `Tab` | Next pane (menu → list → preview) |
+| `Shift+Tab` | Previous pane |
+| `↑↓` / `j` / `k` | Navigate / scroll within focused pane |
+| `Enter` / `→` | Expand tree branch or open leaf list |
+| `Space` | Toggle multi-select on list row |
+| `Enter` / `a` | Action menu (view, delete, download, …) |
+| `r` | Refresh current list |
+| `q` | Quit |
+
+Navigate the **tree** on the left: expand modules (`▸`/`▾`), drill to a **leaf** (marked `•`) — the center list loads only at the last level. Under **Projects → By project**, live projects appear as subnodes with **Tasks** and **Files** leaves.
+
+Optional env for DOCX preview via Document Server (see [`.env.example`](.env.example)):
+
+```bash
+ONLYOFFICE_DOCS_URL=https://docs.example.com
+ONLYOFFICE_DOCS_SECRET=…   # when JWT signing is enabled
+```
+
+Spreadsheet files: inline CSV/JSON preview in the right pane; install
+[`vex`](https://github.com/CodeOne45/vex-tui) on `PATH` for full-screen
+xlsx/csv viewing (`v` on a file row — coming in next iteration).
+
+Integration tests for list loaders and preview (live API only — no mocks):
+
+```bash
+go test -tags=integration ./cmd/office/fetch/... ./cmd/office/preview/...
+```
+
+**Project / task documents (`oo`):**
+
+```bash
+# Project Documents (files module)
+oo projects files list 33
+oo projects files upload 33 ./notes.docx
+oo projects files download 12345 --to ./copy.docx
+oo projects files rename 12345 notes-v2.docx
+oo projects files delete 12345
+oo projects files dedupe 7              # dry-run duplicate report
+oo projects files dedupe 7 --apply      # remove older stem|ext copies per folder

+oo tasks files detach 208 12345
+```
+
+| Subject | Verbs |
+|---|---|
+| `calendar` | `list`, `events`, `add`, `delete` |
+| `projects` | `list`, `get`, `milestones`, `create`, `update`, `delete`, **`files`** (`list`, `upload`, `download`, `rename`, `delete`) |
+| `tasks` | `list`, `get`, `create`, `update`, `delete`, `subtask add`, **`files`** (`list`, `upload`, `detach`) |
+| `users` | `list`, `self` (alias: `oo whoami`) |
+| `contacts` | `list`, `get`, `delete`, `info-add`, `merge`, `dedupe-info` |

+
+The CLI reads only `.env` from the current working directory (godotenv is a
+CLI-only concern — the library itself never loads dotfiles).
+
+Canonical `ONLYOFFICE_*` variables win over aliases. Optional CLI-only aliases:
+`OO_URL` / `OO_USER` / `OO_PASS` → `ONLYOFFICE_URL` / `ONLYOFFICE_USER` / `ONLYOFFICE_PASS`.
+
+Run `oo --help` or `oo <subject> --help` for the full command reference.
+
+> **0.5.0 migration note:** the command tree was flattened per-subject. Old
+> flat names (`oo cal-events`, `oo task-list`, `oo crm-contacts`, …) were
+> replaced by subject-based equivalents (`oo calendar events`, `oo tasks list`,
+> `oo contacts list`). Flags on leaf commands are unchanged.
+
+## oo CLI use cases
+
+The `oo` binary is the day-to-day operator interface. It loads credentials from
+`.env` in the **current working directory** (copy from [`.env.example`](.env.example)):
+
+```bash
+cp .env.example .env
+# ONLYOFFICE_URL=https://office.example.com
+# ONLYOFFICE_USER=you@example.com
+# ONLYOFFICE_PASS=…
+
+go install github.com/eslider/go-onlyoffice/cmd/oo@latest
+oo whoami
+```
+
+Every list command accepts `-o table` (default) or `-o json` for scripting.
+
+### CRM cleanup after imports or sync drift
+
+**Problem:** Duplicate companies (`Acme` / `ACME GmbH`), persons created twice,
+the same email on a contact three times, deals titled ` @ Acme`, or the same
+HR contact linked to a deal twice.
+
+**One-shot fix** — runs every dedupe pass in order:
+
+```bash
+oo crm cleanup -o json
+```
+
+Steps inside `crm cleanup`:
+
+| Step | What it does |
+|------|----------------|
+| `companies` | Merge companies with the same normalized name (slogan variants like `Affirm` / `Affirm — Fraud Engineering` count as one) |
+| `persons` | Merge duplicate persons globally (same first+last) |
+| `company-persons` | Merge duplicate persons under each company |
+| `contact-info` | Remove duplicate email/phone/website rows |
+| `opportunity-members` | Drop duplicate contacts on the same deal |
+| `opportunities` | Merge duplicate deals by title |
+| `fix-titles` | Repair malformed titles (` @ Company` → `Company`) |
+
+**Targeted passes** when you only want one kind of fix:
+
+```bash
+# Duplicate company records
+oo companies dedupe
+
+# Same person entered twice under one employer
+oo companies dedupe-persons
+
+# Global person duplicates (same name, different ids)
+oo persons dedupe
+
+# Repeated email/phone rows on contacts
+oo contacts dedupe-info
+
+# Two deals with the same title
+oo opportunities dedupe
+
+# Same contact attached twice to one deal
+oo opportunities dedupe-members
+
+# Titles like " @ Acme" or extra whitespace
+oo opportunities fix-titles
+```
+
+Merge two known company ids (keeps `INTO`):
+
+```bash
+oo contacts merge FROM_ID INTO_ID
+```
+
+Company ↔ person ↔ deal ↔ project ↔ invoice ↔ mail rules and OO quirks:
+[docs/crm-associations.md](docs/crm-associations.md).
+
+### Invoices (`oo invoices`)
+
+**Problem:** Bill a client deal as Draft, regenerate PDF, prune duplicate PDF
+attachments, prepare OnlyOffice Mail — without inventing a second bill-to company.
+
+```bash
+# Always pass --opportunity at create (update --opportunity often HTTP 400)
+oo invoices create --number INV-2026-01 --contact COMPANY_ID --item ITEM_ID \
+  --price 300 --opportunity DEAL_ID --language de-DE \
+  --line-description "…" --terms $'…' --description $'…' --po "Deal #DEAL_ID"
+
+oo invoices pdf INVOICE_ID --force
+oo invoices pdf-cleanup INVOICE_ID
+oo invoices status INVOICE_ID --status draft
+oo mails draft-invoice --invoice INVOICE_ID --to billing@example.com
+```
+
+**Deal grouping flag** — when the same role at the same company created
+separate deals (`Engineer @ Acme` vs `Engineer`):
+
+```bash
+oo opportunities dedupe --ignore-company-suffix
+oo crm cleanup --ignore-company-suffix
+```
+
+**Inspect before/after:**
+
+```bash
+oo opportunities list --count 200
+oo contacts get CONTACT_ID -o json
+oo crm cleanup -o json
+```
+
+
+### Workspace mail (`oo mails`)
+
+**Problem:** Mail lives in OnlyOffice Mail (`/addons/mail/#inbox`), bound to your
+portal account — not a separate archive service. You want to list, read, or
+remove messages from the shell.
+
+Uses the same `ONLYOFFICE_*` credentials as every other `oo` command.
+
+```bash
+# Which mailbox is linked?
+oo mails accounts
+
+# Folder counters (inbox unread, trash size, …)
+oo mails folders
+
+# Latest inbox messages (API returns 25 per page; --limit paginates automatically)
+oo mails list --folder inbox --limit 50
+
+# Page through older mail
+oo mails list --folder inbox --limit 100 --offset 100
+
+# Other folders
+oo mails list --folder sent --limit 20
+oo mails list --folder spam --limit 100
+
+# Read full message (subject, htmlBody, attachments metadata)
+oo mails get 5664 -o json | jq '{subject, from, to, date}'
+
+# Remove one or more messages (server moves to trash or deletes per Mail rules)
+oo mails delete 5664
+oo mails delete 5664 5663 5661
+
+# Create / update a draft (HTML body field is API "body"; plain text is wrapped)
+oo mails draft --to client@example.com --subject "Rechnung INV-2026-01" \
+  --body "Guten Tag,\n\nanbei die Rechnung.\n\nMit freundlichen Grüßen"
+
+# Attach an OnlyOffice Files document (e.g. invoice PDF file id) to a draft
+oo mails attach 7301 --file-id 12345
+
+# Regenerate invoice PDF (force) + draft + attach (does not send)
+oo mails draft-invoice --invoice 16 --to info@example.com
+```
+
+Matrix / chat URLs in signatures: use plain text
+`chat: https://matrix.to/#/@user:server` — HTML `<a href="…#…">` truncates at `#`.
+
+**Table output** splits the `from` header into `fromName` and `fromAddress`
+(e.g. `Bitfinex` + `no-reply@bitfinex.com`). **JSON output** returns the raw
+API payload.
+
+**Scripting example** — export today's inbox subjects:
+
+```bash
+oo mails list --folder inbox --limit 200 -o json \
+  | jq -r '.[] | "\(.id)\t\(.subject)"'
+```
+
+### Contacts, companies, and deals (everyday CRM)
+
+```bash
+# Search companies
+oo companies list --search acme
+
+# Create company + person with primary email
+oo companies create --name "Acme GmbH" --website https://acme.com
+oo persons create --first Jane --last Doe --email jane@acme.com --company-id 42
+
+# Attach email or LinkedIn to existing contact
+oo contacts info-add 42 --type Email --value jane@acme.com --primary
+
+# Pipeline overview
+oo opportunities list --count 100
+oo opportunities stages
+oo opportunities get 231 -o json
+```
+
+### Calendar and project ops
+
+```bash
+# Next week's events
+oo calendar events --start 2026-06-24 --end 2026-07-01
