+  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

 ### Added — `office` TUI
 
-- **`cmd/office`** — Bubble Tea terminal UI mirroring OnlyOffice Workspace:
-  three-pane layout (module tree, multi-select list, markdown preview).
-  Install: `go install github.com/eslider/go-onlyoffice/cmd/office@latest`.
-- **`cmd/internal/bootstrap`** — shared env loading and client auth for `oo`
-  and `office`.
-- Unit tests for preview formatters, menu/selection model, fetch mappers, and
-  key routing; integration tests under `cmd/office/fetch/` (`-tags=integration`).
+- **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
 
-- **CRM dedupe & cleanup** — `crm_normalize.go`, `crm_dedupe_plan.go`, `crm_dedupe.go`:
-  merge duplicate companies/persons/deals by normalized name; remove duplicate
-  contact-info rows and opportunity members (including same `displayName` with
-  different ids); fix malformed deal titles (` @ Company` → `Company`).
-  `MergeContacts`, `UpdateOpportunityTitle`, `ListAllContacts`,
-  `ListAllOpportunities`, `DeleteContactInfo`, `RemoveOpportunityMember`,
-  `IsOpportunityMember`, `HasContactInfo`, `CleanupCRM`.
-- Slogan-aware grouping: `StripSloganSuffix`, `CompanyGroupingKey` merge names
-  like `Affirm` and `Affirm — Fraud Engineering` (companies, deals, members).
-- **Workspace mail** — [`mails.go`](mails.go): `ListMailAccounts`, `ListMailFolders`,
-  `ListMailMessages`, `GetMailMessage`, `RemoveMailMessages` against OnlyOffice
-  Mail addon (`/api/2.0/mail/*`).
-- [`crm_integration_test.go`](crm_integration_test.go) — live merge, rename,
-  dedupe smoke tests.
+- `UpdateProjectStatus` — `PUT /api/2.0/project/{id}/status` for open/closed lifecycle.
 
-### Added — CLI
+## [0.5.1] — 2026-06-24
 
-- `oo mails accounts|folders|list|get|delete` — OnlyOffice Workspace mail (same `ONLYOFFICE_*` creds).
-- `oo companies dedupe|dedupe-persons`, `oo persons dedupe`, `oo contacts dedupe-info`,
-  `oo opportunities dedupe|dedupe-members|fix-titles`, `oo crm cleanup`.
+### Added — `office` TUI
 
-### Added — CI/CD
+- **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.
 
-- GitHub Actions: `test.yml` (vet, unit tests, `oo` build), `release-please.yml`
-  (semver from conventional commits), `release.yml` (GoReleaser binaries for `oo`).
+### Changed — `office` TUI
 
-### Changed — CLI
-
-- README: expanded **oo CLI use cases** (CRM cleanup, applications sync, mail, contacts).
-- `oo applications sync` — empty position uses company-only deal title; skips
-  duplicate opportunity members; paginated find-or-create lookups.
-- `oo` now loads OnlyOffice credentials only from `.env` in the current
-  working directory.
-- Produktor.io shorthand env names are accepted by the CLI dotenv loader:
-  `OO_URL` → `ONLYOFFICE_URL`, `OO_USER` → `ONLYOFFICE_USER`, and
-  `OO_PASS` → `ONLYOFFICE_PASS`. Canonical `ONLYOFFICE_*` values still win
-  when already set in the process environment.
+- 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.
