+# DataDeck
+
+**Your CSV files, alive inside Obsidian.** DataDeck opens plain `.csv` files
+as rich, editable views — cards, kanban, an editable table, charts with
+best-fit lines and formula overlays, a habit dashboard, a tasks board, a
+one-entry-at-a-time focus reader, and an interactive travel map. Everything
+edits in place and writes straight back to the one canonical CSV file: no
+database, no shadow copies, no lock-in. Your data stays a text file that
+diffs, syncs, and outlives any tool.

+
+</details>
+
+## Highlights
+
+- **Nine view modes**, auto-offered based on the columns in the file — a
+  books CSV gets a library, a habit log gets a dashboard, a tasks file gets
+  a project board, a travel log gets a world map.
+- **Everything is editable** — click a cell, toggle a habit, drag nothing:
+  edits debounce-save back to the CSV. Notes-style columns render and edit
+  as **Markdown**.
+- **Charts** like a tiny ggplot: scatter/line of any column pair, color-by
+  category (hue), size-by, per-series least-squares fits with R², `y = f(x)`
+  formula overlays, week/month bucketing, rolling-average smoothing, bar
+  aggregates for categorical axes, and one-click PNG export.
+- **Embed blocks** put live views inside any note: `csv-view` (table /
+  cards / kanban), `csv-chart`, `csv-tasks` (a cross-file tasks board),
+  `csv-random` (quote of the day), and `csv-add` (a mobile-friendly entry
+  form).
+- **Sync-safe saves** — if the file changed on disk while you were editing
+  (another device, another tab), the other version is stashed to `Archive/`
+  instead of being silently overwritten.
+- **Works on mobile.** Compact toolbars, one-scroll modals, touch-friendly
+  pickers.
+
+## Installation
+
+Until DataDeck is in the community store:
+
+- **Via [BRAT](https://github.com/TfTHacker/obsidian42-brat):** add
+  `SVM0N/datadeck` as a beta plugin.
+- **Manual:** grab `main.js`, `manifest.json`, `styles.css`, and
+  `world-map.svg` from the latest
+  [release](https://github.com/SVM0N/datadeck/releases) into
+  `<vault>/.obsidian/plugins/datadeck/`, then enable **DataDeck** in
+  Settings → Community plugins.
+
+> `world-map.svg` is loaded at runtime for the travel view — include it when
+> installing manually.
+
+## Quick start
+
+1. Open any `.csv` file — DataDeck takes over the tab and picks a sensible
+   view from the columns it finds.
+2. Switch views with the toolbar dropdown; **⚙ Config** sets per-file column
+   roles (title, category, status, notes, image…), column types (checkbox /
+   categorical / date), and the default view.
+3. **+ Add** opens an entry form with the right control per column: dropdowns
+   for categorical columns, a date picker for dates, toggles for 0/1 habit
+   columns, a Markdown textarea for notes.
+4. No CSV yet? Run a palette command: **Create tasks / travel / habit
+   tracker / chart file** scaffolds one preconfigured for its view.
+
+## View modes
+
+The toolbar dropdown offers only the modes that make sense for the file's
+columns:
+
+| Mode | Appears when… | What it shows |
+|------|---------------|---------------|
+| **Table** | always | Editable spreadsheet: resizable columns, click-to-sort headers, sticky header |
+| **Cards** | any groupable column | A library grouped by category — status dots, star ratings, tags, cover images, per-file sort |
+| **Kanban** | any groupable column | Columns by category (or any column via "Group by" — year columns bucket into decades), status subgroups, inline note editing |
+| **Chart** | a numeric column (2+ rows) | Scatter/line of any column pair with hue, size-by, fits, formulas, smoothing, bucketing, and bar aggregates — see [Charts](#charts) |
+| **Dashboard** | a date column | Habit tracker: daily toggles, progress chart, streaks, per-habit GitHub-style calendars |
+| **Tasks** | due/priority columns, or task-like type values | Project board: rows grouped by project, split into Tasks / Idea / Note sections, click-to-toggle done, overdue flags |
+| **Stats** | a category/status/rating/author column | Bar-chart insights: status breakdown, categories, rating histogram, entries per year — bars click through to the filtered library |
+| **Focus** | any non-empty file | One entry at a time with big typography — built for quotes and vocabulary. ←/→ keys navigate |
+| **Travel** | `country` + trip-date columns | World choropleth, trip timeline, per-country day totals, residency day-counters — see [Travel view](#travel-view) |
+
+## Charts
+
+Pick **Chart** in the toolbar (or embed a `csv-chart` block):
+
+- **X / Y** — any numeric or date column; a date X renders a connected time
+  series, numeric pairs render as scatter dots.
+- **Color** — ggplot-style hue: one colored series per value of a
+  categorical column.
+- **Size** — a numeric column mapped to point radius (area-true sqrt scale).
+- **Best fit** — per-series least-squares line with the equation and R²
+  (phrased as an per-day trend for date axes).
+- **Smooth** — a 7-day rolling average drawn over faint raw dots.
+- **By week / month** — bucket a time series with a sum / avg / count
+  aggregate ("km per week, one line per person").
+- **Bar mode** — pick a *categorical* X and the chart becomes bars with a
+  count / sum / avg aggregate; hue makes grouped bars; comma-separated
+  columns (genres, tags) count once per value.
+- **`y = f(x)` overlay** — type `2x^2 - 3x + 1` or `10 sin(x/2)`; parsed by
+  a small built-in evaluator (`+ - * / % ^`, parentheses, implicit
+  multiplication, `sin cos tan sqrt log ln exp abs floor ceil round min max
+  pow`, `pi`/`e`). No `eval`.
+- **⬇ PNG** — saves the chart as an image next to the CSV.
+
+## Embed blocks
+
+Live views inside any note. All paths resolve like links: a bare name is a
+sibling of the note, `../` walks up, and anything else is vault-relative.
+
+### `csv-view` — table / cards / kanban in a note
+
+````
+```csv-view
+file: ../movies.csv
+mode: kanban             ← table | cards | kanban   (default: table)
+height: 480              ← optional max content height in px
+collapse: Removed, Done  ← optional: card groups collapsed by default
+```
+````
+
+Fully editable — inline cells, status chips, the entry expander, + Add, and
+delete-with-undo all write back to the source CSV. Other open views of the
+same file re-sync automatically.
+
+### `csv-chart` — a chart (or pure function plot) in a note
+
+````
+```csv-chart
+file: ../health.csv      ← omit for a formula-only plot
+x: date                  ← default: date column, else first numeric
+y: weight                ← default: first numeric column ≠ x
+hue: person              ← optional color-by column
+size: effort             ← optional numeric column → point radius
+agg: sum                 ← aggregate for bar mode / bucket (count | sum | avg)
+bucket: week             ← date X only: week | month buckets
+smooth: true             ← date X only: rolling mean (true = 7 days, or a number)
+fit: linear              ← best-fit line(s) with equation + R²
+formula: 0.5x + 2        ← y = f(x) overlay; the whole plot when there's no file
+xmin: -10                ← formula-only domain (default -10 … 10)
+xmax: 10
+height: 280
+```
+````
+
+Read-only; re-renders when the source CSV changes.
+
+### `csv-tasks` — a cross-file tasks board
+
+````
+```csv-tasks
+folder: Projects         ← scan recursively for task-shaped CSVs ("/" = whole vault)
+files: extra.csv         ← and/or an explicit comma-separated list
+height: 600
+```
+````
+
+Merges task rows from many CSVs into one board. Columns map onto a canonical
+set (Title / Type / Project / Priority / Due / Status / Notes) by name
+aliases — `deadline`, `state`, `kind`, `area`… all resolve. A file without a
+Project column uses its **basename** as the project, so one-CSV-per-project
+folders just work. Every edit writes back to the row's source file;
+right-click a row for "Open source".
+
+### `csv-random` — a random entry (quote of the day)
+
+````
+```csv-random
+file: ../quotes.csv
+field: Quote             ← optional; defaults to the first column
+```
+````
+
+Re-rolls on every render and via its ↻ button — made for daily-note
+templates.
+
+### `csv-add` — an entry form in a note
+
+````
+```csv-add
+file: ../habits.csv
+```
+````
+
+A compact, grouped add/update form (date pre-filled with today, toggles for
+habit columns, dropdowns with a custom escape hatch). On habit-tracker files
+it pre-fills from the existing row for the picked date, so updating a day
+never wipes what's already logged.
+
+## Travel view
+
+For a flat travel CSV with these columns:
+
+```
+date_entered,date_left,country,city,visa_status,notes,source,resolved
+```
+
+- `country` is ISO-2 (`US`, `FR`, …); `source` is `confirmed`, `inferred`
+  (e.g. photo-derived), or `conflict`.
+- Confirmed countries render gold; photo-only countries blue; conflict rows
+  and photo rows overlapping a confirmed trip are excluded from counts.
+- Click a country (map, table, or timeline) for a per-country trip panel.
+- Blank/partial dates (`2022-06-??`) are allowed — visited-but-undated. A
+  blank `date_left` counts as an ongoing stay ("📍 Currently in …").
+
+### Residency counters
+
+Configurable day-gauges (e.g. Schengen 90/180) render in the travel view.
+Each rule counts *days in the listed countries within a window (calendar
+year / rolling N days / all time), minus exempt visa rows, against a
+threshold*. Add rules in **Settings → DataDeck → Residency rules**. These
+are **indicators, not legal or tax advice**.
+
+## Anki sync
+
+The **🎴 Anki** toolbar button pushes rows to
+[Anki](https://apps.ankiweb.net/) as flashcards — great for quotes and
+vocabulary files. One Basic note per row: the front is the title column (or
+your ⚙ Config pick), everything else joins onto the back. Decks are named
+after the file and re-syncs skip cards that already exist, so it's safe to
+click repeatedly.
+
+Requires the [AnkiConnect](https://ankiweb.net/shared/info/2055492159)
+add-on and the Anki desktop app running; desktop-only (it talks to
+`http://127.0.0.1:8765`).
+
+## Commands
+
+- **Add entry to current CSV** — the + Add form, hotkey-able.
+- **Cycle view mode** — steps through the file's valid views.
+- **Create tasks / travel / habit tracker / chart file** — scaffold a new
+  CSV preconfigured for that view.
+
+## Privacy & network use
+
+- All data stays in your vault. **No telemetry, no analytics, no network
+  calls** — with one exception: the optional Anki sync button talks to
+  AnkiConnect on `localhost` (`127.0.0.1:8765`) and only when you click it.
+- Per-file settings live in the plugin's `data.json` inside your vault.
+
+## Development
+
+```bash
+npm install
+npm run build        # bundle main.ts → main.js (esbuild)
+npm run dev          # watch build
+npm run test:all     # unit + jsdom view-smoke tests (no Obsidian needed)
+npm run typecheck    # tsc --noEmit
+```
+
+To deploy straight into your own vault while developing, point the plugin
+at it once — `npm run deploy` copies the built assets into local symlinks
+that you create (they're gitignored):
+
+```bash
+ln -s "<your-vault>/.obsidian/plugins/datadeck" datadeck
+ln -s "<second-vault>/.obsidian/plugins/datadeck" datadeck-work   # optional
+npm run build:deploy
+```
+
+Vault-touching dev tooling reads the `OBSIDIAN_VAULT` environment variable
+for your vault's path (no default).
+
+`main.ts` holds the `CardView` lifecycle and plugin entry point; each view
+renderer and feature lives in `src/` as a free function taking the view —
+the same functions power the full-page views and the embed blocks. Tests run
+the renderers against a jsdom DOM with Obsidian's DOM helpers polyfilled
+(`test-support/`); every view has smoke coverage.

+
+## What this is
+
+An Obsidian plugin that opens `.csv` files as a kanban, table, dashboard, library, stats, focus, or travel-map UI. Originally built for book-library and habit-tracking use cases, since generalized to any row/column CSV data. View modes:
+- **Dashboard** — date-based habit tracking with chart, streaks, and stats (auto-detected when first column is dates).
+- **Library** — grid of cards with filters (status, genre, search), collapsible genre sections, green-dot for done items, ratings, tags.
+- **By Genre** — kanban grouped by category column, with status subgroups inside each column.
+- **Table** — spreadsheet view with resizable columns; click a header to sort (asc → desc → off, numeric-aware, empties last). Sticky header: in table mode the content area gets `--no-yscroll` and `.csv-table-wrapper` becomes the y-scroller, giving `position: sticky` a scrollport.
+- **Travel** — world choropleth + timeline + residency counters for travel-log CSVs. Countries are selectable (map shape / Countries-table row / timeline segment) → detail panel under the map with every trip there; timeline dims other countries while selected. Stats row includes Cities + Longest trip; a "📍 Currently in …" banner shows when today falls inside a confirmed trip (`currentStay` in travel-data, blank `date_left` = ongoing, partial dates excluded). Timeline years carry "Nd · M countries" summaries.
+- **Stats** — pure-CSS bar charts (status / category / rating / year / top-author breakdowns); deliberately no Chart.js. Shown whenever the file has a chartable column (`hasStatsColumns`).
+- **Focus** — one entry at a time with big typography and prev/random/next nav (←/→ keys); built for quote/dictionary files. Shown for any non-empty file.
+
+Cards/Kanban are available whenever the file has *some* groupable column — per-file "Group by" pick → detected category column → auto-picked fallback (`effectiveGroupCol` in `view/kanban.ts`, scoring via `pickFallbackGroupCol` in `utils.ts`: skips notes/date/title and all-unique or single-value columns, prefers ~8 distinct values). Files like travel logs with no Category column still get Cards/Kanban grouped by e.g. country or city.
+
+The plugin used to also handle `.xlsx` (via SheetJS lazy-loaded chunk + `_csv_helpers/` mirror for Dataview). That whole stack was retired in commit "SWITCH TO CSV AS MAIN" — a round-trip validator proved the migration lossless before cutover.
+
+## FileView (not TextFileView)
+
+Extends `FileView` directly. Historical reason: `TextFileView` decodes everything as UTF-8 before handing off — destroyed binary xlsx data when xlsx was still a registered extension. Now that the plugin is CSV-only, `TextFileView` would technically work, but `FileView` is left in place because the modal/view lifecycle is identical and switching is pure churn.
+
+- **CSV read:** `vault.read()` → `parseCSV` (Papa wrapper in `src/utils.ts`)
+- **CSV save:** `vault.modify()` with `Papa.unparse(...)`
+
+All saves are debounced 600ms via `scheduleSave()` → `doSave()`. Edits commit to disk automatically — no explicit save button. Read/write failures surface to the user as `Notice`s, not silent `console.error`s.
+
+## Data model
+
+```typescript
+interface CSVRow { [key: string]: string; }
+// headers: string[]  — column order preserved
+// rows: CSVRow[]     — all values stored as strings
+```
+
+Everything in memory. `onLoadFile` populates, `doSave` flushes.
+
+## View modes
+
+`type ViewMode = "kanban-genre" | "table" | "dashboard" | "library" | "travel" | "stats" | "focus"`. Switched via toolbar (only modes valid for the file's columns are shown). Full re-render on each switch.
+
+## Module map (main.ts)
+
+### Top-level
+
+**`showSelectPicker(anchor, currentValue, allValues, onSelect, container, opts?)`** (in `src/utils.ts`)
+Floating dropdown for select fields. `opts.multi` (used when `isMultiValueColName(h)` — Category/Genres/Tags/Themes/Topics by name) turns it into a toggle list: items check on/off, every toggle live-commits the comma-joined string via `onSelect`, the picker stays open until Done/Esc/outside-click, and comma-joined data values are split into individual options. Fixed-positioned below anchor. Search/filter, clear, "+ Add new", arrow-key navigation + Enter to commit. On desktop, dismisses on scroll/resize of any ancestor (capture-phase listener) and flips up when there isn't room below. On touch (`matchMedia("(pointer: coarse)")`) those listeners are skipped — focusing the search input on iOS pops the virtual keyboard which fires `resize`, which would dismiss the picker immediately.
+
+### Classes
+
+**`AddEntryModal extends Modal`**
+"+ Add" toolbar button. Labeled form for every column. Notes → `<textarea>`, select cols → chip that opens `showSelectPicker`, everything else → `<input type="text">`. Requires at least one field filled.
+
+**`NoteExpanderModal extends Modal`**
+Wide modal (~780px) for viewing/editing a full entry. Three sections: header (title), fields bar (all non-notes columns, inline-editable), notes section (rendered markdown by default, click to enter edit). Works on a shallow copy; Cancel discards.
+
+**`FileConfigModal extends Modal`**
+"⚙ Columns" toolbar button. Dropdowns for category/status/notes/default-view + checkbox grid for habit-columns and `cardFields`. Saved to `settings.fileConfigs[filePath]`. The Default-view options are passed in from `availableModes(view)` (same source as the toolbar's view dropdown), so the picker offers exactly the modes this file can render; a saved mode the file can no longer render shows as "(no longer available)" so it can be cleared.
+
+**`CardView extends FileView`**
+
+| Method | Purpose |
+|---|---|
+| `onLoadFile(file)` | Reads CSV via `vault.read` + `parseCSV`, applies per-file default mode, calls `renderView()` |
+| `doSave()` | `Papa.unparse` → `vault.modify` |
+| `scheduleSave()` | 600ms debounce wrapper |
+| `renderView()` | Clears and rebuilds entire `contentEl` |
+| `renderToolbar(root)` | Mode buttons + search + ⚙ Columns + 💾 Backup + 🎴 Anki + + Add (phones collapse secondaries into ⋯) |
+| `renderKanbanGenre/Table/Dashboard/Library/Stats/Focus` | The view renderers (free functions in `src/view/`) |
+| `renderMarkdownInto(el, text)` | MarkdownRenderer wrapper tied to the view's render Component (used by Focus) |
+| `renderKanbanCard(container, row, ...)` | Single kanban card |
+| `renderSelectField/makeEditable` | Inline editors |
+| `openNoteExpander/openAddModal` | Modal openers |
+| `openOrCreateNotes(row)` | Creates/opens sidecar `.md` |
+| `resolveCol(candidates)` | First header matching any candidate (case-insensitive) |
+| `getNotesCol/getStatusCol/getCategoryCol/getDateCol` | Per-file override → fallback chain |
+| `getFilteredRows()` | Rows matching current search query |
+| `deleteWithUndo(row)` | Routes every delete path through a 6s Notice with Undo |
+| `backupToArchive()` | Copies the current csv to `Archive/<basename>_YYYY-MM-DD.csv` (byte-identical, `readBinary` → `writeBinary`) |
+
+The class constructor takes a typed `persistSettings: () => Promise<void>` callback. Previously `saveFileCfg()` reached the plugin via `(app as any).plugins.plugins["datadeck"]?.saveSettings()` — brittle and untyped. Now passed explicitly.
+
+**`CardViewSettingTab extends PluginSettingTab`**
+Global settings UI.
+
+**`CardViewPlugin extends Plugin`**
+Entry point. Registers view for `csv`, registers `csv-add`, `csv-refresh`, and `csv-random` (random entry card with ↻ re-roll, `src/random-block.ts`) code block processors, plus palette commands: `add-entry`, `cycle-view-mode` (→ `CardView.cycleMode`, modes from `availableModes` in `view/toolbar.ts`), and one `create-<id>` per entry in `FILE_TEMPLATES` (scaffold a new CSV with that view's canonical columns, pin its `defaultMode`, open it — `createTemplateFile`). `vault.on("rename")` / `vault.on("delete")` hooks migrate or drop `fileConfigs` keys so per-file config survives file moves (see `migrateFileConfigKey` in `src/utils.ts`).
+
+Key methods:
+- `renderAddEntryForm(source, el, ctx)` — renders the `csv-add` code block as a form. Parses `file:`, reads headers, auto-detects select fields (cols with ≤15 unique values), writes new entries directly to the file. For habit-shape files (file has a date col), pre-fills from existing row matching the date input → submit reads as "Update". Title flips to "Updating ‹date›" and submit button label flips to "Update" (vs "Add") when the date matches.
+
+## Column auto-detection (fallback chains)
+
+When no per-file override is set, columns are resolved by trying candidates in order against actual headers (case-insensitive). First match wins.
+
+| Role | Candidates |
+|---|---|
+| Notes | Notes → Note → Summary → Review → Quote → Quotes → Comment → Comments → Description → Annotation |
+| Category | Category → Categories → Genre → Genres → Type → Types → Tag → Tags → Topic → Topics → Subject → Section |
+| Status | Status → State → Progress → Stage → Read |
+| Title | Title → Name |
+| Author/subtitle | Author → Authors → Director → Artist → Creator → By |
+
+## Per-file configuration
+
+```typescript
+interface FileConfig {
+  categoryColumn?: string;
+  notesColumn?: string;
+  statusColumn?: string;
+  habitColumns?: string[];   // dashboard habit toggles
+  cardFields?: string[];     // fields surfaced on Library/Kanban cards
+  defaultMode?: ViewMode;
+  sortNewestFirst?: boolean; // table sort toggle
+  kanbanGroupCol?: string;   // kanban "Group by" column (unset = category;
+                             // year-like columns bucket into decades)
+  librarySort?: LibrarySort; // Cards-view sort: status|title|rating|year
+}
+```
+
+Stored in `settings.fileConfigs[file.path]`. Accessed via `this.fileCfg` getter. Saved via `saveFileCfg(cfg)`. `undefined` fields fall back to the chain above. Keys follow file renames/deletes via vault hooks (see `migrateFileConfigKey` in `src/utils.ts`, 4 tests in `test-plugin-logic.mjs`).
+
+**Habit columns** — if `habitColumns` is unset, auto-detected by scanning for columns with binary values (0/1, true/false, yes/no, empty). FileConfigModal has a checkbox grid to override.
+
+**cardFields** — if unset, auto-detects author + year + rating + theme. Checkbox grid in FileConfigModal lets the user pick which fields to render on cards.
+
+## Settings (`CardViewSettings`)
+
+| Field | Default | Description |
+|---|---|---|
+| `defaultMode` | `"kanban-genre"` | Global default opening view |
+| `notesColumns` | `["Notes","notes",...]` | Legacy list — superseded by `getNotesCol()` chain but kept for CSV fallback |
+| `statusColumn` | `"status"` | Global status column name (overridden per-file) |
+| `categoryColumn` | `"category"` | Global category column name (overridden per-file) |
+| `notesSubfolder` | `"Notes"` | Subfolder for sidecar `.md` files relative to the data file |

+
+## Notes system
+
+### Inline notes (in the xlsx cell)
+Any column resolved by `getNotesCol()` is the notes field.
+
+- **Kanban card** — preview (120 chars, markdown stripped) is itself the click-to-edit affordance. Empty state shows hover-revealed "+ Add note". Scroll position saved before opening expander, restored via multi-layer approach (immediate + double rAF + setTimeout). Textarea focus uses `preventScroll: true`.
+- **Table** — 2-line preview. Clicking the cell opens `NoteExpanderModal`.
+
+### Sidecar notes file
+"✚ Notes file" / "📄 Open notes file" button. Path: `<csv-folder>/<notesSubfolder>/<sanitized-title>.md`. Created with YAML frontmatter from all non-notes columns (serialized via Obsidian's `stringifyYaml` — hand-built `key: "value"` lines broke on backslashes/newlines in cell values) plus a `source` property wikilinking back to the CSV (skipped if a column is named "source"), + inline notes as seed content. Opens in new tab. `notesFileExists(row)` checks via `vault.getAbstractFileByPath()`.
+
+## Dashboard view (date-based files)
+
+Auto-selected when first column is detected as dates (YYYY-MM-DD pattern or named "date"/"day"/"datum").
+
+- **Date navigator** — prev/next buttons, date dropdown, Today button
+- **Habit toggles** — clickable ○/● for each habit column
+- **Line chart** — habits completed per day (Chart.js, lazy-loaded)
+- **Stats bar** — days logged, average per day, perfect days, current streak, best streak
+- **Per-habit cards** — individual stats with progress bar; click expands a heatmap timeline
+
+### Streak calculation
+Streaks **break if a day is missed**. Algorithm checks consecutive rows are exactly 1 day apart. Current streak starts from today (or yesterday if today has no entry) and counts backwards only while dates are consecutive.
+
+### Per-habit timeline
+Heatmap grid: done (green), missed (red), no entry (grey). Month separators. Individual habit streak stats. Click card again or ✕ to close.
+
+## Kanban by Genre
+
+- Genres from splitting Category column on `,` — multi-genre entries appear in multiple columns
+- Columns sorted alphabetically; column titles use `var(--text-accent)` to match Library headers
+- Within each column, rows grouped by status with colored labels: `In progress` → blue, `Finished/Watched` → green, `Not started/Unwatched` → grey, `dropped` → red
+- Status order: In progress → Finished → Not started (then any others)
+- Right-click context menu: change status, open/create notes file, delete (uses `deleteWithUndo`)
+- On mobile, CSS scroll-snap + `calc(100vw - 60px)` columns so swipe lands cleanly on the next column (desktop columns are 260–300px and looked half-cut on phones)
+- Single scrollbar per direction — kanban content area gets a `.csv-content-area--no-yscroll` modifier and column bodies fill viewport via `min-height: 0` (the flex-min-content trap), so the page doesn't double-scroll
+
+## Chip truncation
+Long non-select field values in kanban cards truncate at 40 chars with `…`. Full text on hover via `title=`. CSS enforces `max-width: 200px; text-overflow: ellipsis` on `.csv-chip-value` as a second layer.
+
+## Mobile dashboard system (retired from the plugin)
+
+The plugin's views are natively mobile-friendly, so the old DataviewJS dashboard generator (a "📱 Mobile" toolbar button that stamped `<folder>/Mobile/<basename>.md` from templates) was removed from the published plugin. The `csv-add` and `csv-refresh` blocks those dashboards used remain fully supported for back-compat, and the generator lives on as local (gitignored) tooling.
+
+Design lesson worth keeping: both the `csv-add` write target and any external read target must point at the **same canonical CSV**. The pre-migration `_csv_helpers/` mirror (kept in sync via three separate code paths) is exactly the bug class to refuse if a future change tempts you toward a "secondary copy" of the data.
+
+### csv-add code block
+The plugin registers a `csv-add` markdown code block processor. Renders a labeled form for every column. Auto-detects column types from existing data: cols with ≤15 unique values become dropdowns with a "+ Custom" option. Writes directly to the CSV file. For habit-shape files (date col present), `syncFromExisting()` pre-fills the form when the date input matches an existing row; the card gets an `is-updating` class (subtle accent ring + tinted title) and the submit button label flips to "Update".
+
+```csv-add
+file: ../books.csv
+```
+
+File-path forms (resolved by `resolvePath` in `src/utils.ts`, 9 tests in `test-plugin-logic.mjs`):
+- `books.csv` — sibling of the current note
+- `../books.csv` / `../../foo.csv` — walked up from current folder (clamps at vault root)
+- `Library/books.csv` — vault-relative
+
+Generated dashboards always emit the `../` form so the data folder is portable — move the folder anywhere in the vault and dashboards still resolve.
+
+### Three gotchas in the library template
+- **CSV type coercion.** `dv.io.csv` parses with `dynamicTyping: true`, so a numeric-looking title like the book "1984" comes back as `Number`. Any string-only call (`.localeCompare`, `.toLowerCase`, `.split`) on a raw field must be wrapped in `String(...)`.
+- **titleKey fallback.** Quotes/dictionary have no Title/Name column — the library template falls back through `Quote/Headline/Phrase`, then `headers[0]`.
+- **Negative status values clutter the kanban.** `NEGATIVE_STATUS` filters out `no/not started/unwatched/unread/todo`. Affirmative finished values (`yes/watched/seen/finished/read`) render as a green dot on the title row, not a "Yes" chip.

+```
+
+**Renderer pattern.** Each view renderer is a free function `renderX(view, container)`
+taking the `CardView` via a type-only import (no runtime cycle); the members they
+reach are public on `CardView`. `dashboard.ts` owns the lazy `loadChart` so non-dashboard
+sessions never load Chart.js.
+
+**Test net.** `test-view-smoke.mjs` (+ `test-support/`) renders each view into jsdom
+with Obsidian's `createEl`/etc. polyfilled onto `Element.prototype`; renderers are
+driven by hand-built `view` stubs. `npm run test:view` / `test:all`. Add a renderer →
+add a smoke case.
+
+*(Optional future polish: a `ViewContext` interface so renderers depend on an explicit
+contract instead of the whole `CardView` type. Not needed — current setup is type-safe.)*

+Live data is any folder of CSVs in the vault. `Mobile/` and `Archive/` subfolders are created as needed by the plugin on first click of the respective buttons; `Archive/` also holds `*_pre-csv-migration.xlsx` originals preserved by the migration script and `* sync-conflict *.csv` stashes from the sync guard.
+
+## Build & Deploy
+
+```bash
+npm install              # Install dependencies
+npm run build            # Build main.js (minified, ~720 KB)
+npm run build:deploy     # Build and copy to Obsidian plugin folder
+npm run dev              # Watch mode (rebuild on changes, unminified, inline sourcemaps)
+npm run deploy           # Copy already-built files to Obsidian plugin folder
+```
+
+Watch mode is unminified with inline sourcemaps so DevTools in Obsidian stays readable during dev. Production builds (`npm run build`, `build:deploy`) minify.
+
+Install in Obsidian: copy `main.js`, `manifest.json`, `styles.css` into `<vault>/.obsidian/plugins/datadeck/` and enable in Community plugins. The `datadeck/` folder in this repo is a symlink to that path, so `npm run deploy` (or `build:deploy`) updates the plugin in place. Reload with `npm run reload` (Obsidian CLI — see below) or Cmd+R in Obsidian.
+
+## Testing
+
+```bash
+npm run test             # Plugin logic tests (88)
+npm run test:csv         # CSV parser tests (6)
+npm run test:all         # All of the above (115 total)
+npm run typecheck        # TypeScript type checking
+npm run check            # Full check: typecheck + tests + build + deploy
+```
+
+### Test surface
+
+- **CSV parsing** — CRLF, quotes, escaping, long fields, embedded newlines, Unicode, empty input.
+- **Column resolution** — case-insensitive matching, fallback chains.
+- **Round-trip serialization** — Papa unparse → parseCSV round-trip stability.
+- **Title case, binary col detection, date col detection, search filtering.**
+- **`findExistingRowByDate` / `mergeHabitEntry` / `sortByDate`** — habit-tracker write paths.
+- **`formatRatingForDisplay`** (9) — empty / unrated / glyph-pass-through / numeric / text-mapped / out-of-range / unknown-on-rating-col / unknown-on-other-col.
+- **`resolvePath`** (9) — sibling / vault-relative / `../` / `../../` / `./` / mixed / root-clamp.
+- **`migrateFileConfigKey`** (4) — rename moves config, delete drops it, no-op for missing keys, caller-set new entry wins.
+- **Mobile dashboard simulator** (21) — per-file no-throw + render assertions, movie-specific compact-grid/year/rating/theme checks, generic-table wrap, watched-dot count.
+
+The mobile simulator runs the dataviewjs body against real CSVs via Papa Parse with `dynamicTyping: true`, so any drift between template and rendered output fails the test the same way it would fail in Obsidian.
+
+## Active dev loop
+
+```bash
+npm run build:deploy && npm run test:all
+npm run reload           # hot-reload the plugin in the running Obsidian (no Cmd+R)
+npm run errors           # surface any runtime errors the reload produced
+```
+
+Mobile-dashboard regeneration/verification lives in the gitignored `local/` tooling (`OBSIDIAN_VAULT` env var required).
+
+`npm run check:live` chains the whole thing: typecheck + tests + build + deploy + reload + error check.
+
+## Obsidian CLI (driving the running app)
+
+The `obsidian` CLI (ships with Obsidian ≥1.12, desktop must be running) can drive the live app — this replaces the manual "Cmd+R and click around" step for most verification. Full reference: `obsidian help` or https://help.obsidian.md/cli.
+
+```bash
+obsidian plugin:reload id=datadeck      # reload after build:deploy (= npm run reload)
+obsidian dev:errors                          # captured plugin errors (= npm run errors)
+obsidian dev:console level=error             # console output
+obsidian dev:screenshot path=shot.png        # screenshot the app for visual verification
+obsidian dev:dom selector=".csv-card" text   # inspect rendered DOM (CSS classes: css-classes.md)
+obsidian dev:css selector=".csv-chip-value" prop=max-width
+obsidian dev:mobile on                       # toggle mobile emulation (kanban scroll-snap etc.)
+obsidian eval code="app.vault.getFiles().length"
+```
+
+Typical verify pass after a change: `npm run check:live`, then `dev:screenshot` / `dev:dom` against an open CSV view instead of eyeballing, and `dev:mobile on` to check the phone layout without a device. Commands target the most recently focused vault; pass `vault="<name>"` first if several are open.
+
+## Bench
+
+`node bench-load.mjs main.js` measures V8 parse cost on the bundle text + parse+top-level eval. 5-run averages. Current baseline:
+
+| Stage | Size | Parse only | Parse+eval |
+|---|---|---|---|
+| Eager + unminified (historical) | 1338 KB | 2.6 ms | 3.4 ms |
+| Lazy + unminified | 1533 KB | 2.0 ms | 0.8 ms |
+| Lazy + minified (with SheetJS) | 720 KB | 1.5 ms | 0.9 ms |
+| **CSV-only (current, post-migration)** | **297 KB** | **0.7 ms** | **0.5 ms** |
+
+Chart.js is dynamic-imported (only initialises when dashboard renders). SheetJS is gone entirely — the CSV-only migration retired it. Run the bench after any refactor that touches imports/bundling.
+
+## Settings persistence (data.json)
+
+All plugin settings saved to:
+
+```
+<vault>/.obsidian/plugins/datadeck/data.json
+```
+
+Obsidian writes this automatically via `saveData()` / `loadData()`. Persists across sessions, restarts, and devices (travels with vault on iCloud sync). Example:
+
+```json
+{
+  "defaultMode": "kanban-genre",
+  "statusColumn": "status",
+  "categoryColumn": "category",
+  "notesSubfolder": "Notes",
+  "columnWidths": { "Name": 240, "Notes": 400 },
+  "selectColumns": ["Category", "Type", "Rating", "Status"],
+  "fileConfigs": {
+    "Library/books.csv": {
+      "categoryColumn": "Category",
+      "notesColumn": "Notes",
+      "statusColumn": "Status",
+      "defaultMode": "kanban-genre"
+    }
+  }
+}
+```
+
+File-rename/delete hooks migrate `fileConfigs` keys automatically — old `Library/Data/...` entries in the user's live `data.json` may still be orphaned from before that fix; hand-edit if you want them back. The SWITCH TO CSV AS MAIN migration also rewrote `*.xlsx` keys to `*.csv` in-place.
+
+## Manual test checklist
+
+- Open `books.csv` → opens in By Genre view.
+- Genre columns render with status subgroups (In progress / Finished / Not started).
+- Hover card → buttons appear; click the note preview → textarea opens inline; blur saves and scroll position restored.
+- Click "⤢ Expand" → NoteExpanderModal opens; fields bar shows all columns; text fields click-to-edit; select chips open picker; click rendered notes to edit; Cancel discards; Save & close commits.
+- Click "+ Add" → AddEntryModal opens; all fields present; select chips work; submit adds row, notice shown.
+- Click "⚙ Columns" → FileConfigModal opens; dropdowns show all headers; checkbox grid for habit cols + cardFields; save persists to data.json.
+- Long chip values truncate with `…`; full text shown on hover.
+- Switch to Table view; resize columns; click notes cell → NoteExpanderModal opens (no inline editing).
+- Right-click kanban / library / table row → change status, delete (with undo).
+- Delete a row → 6s Notice with Undo button → click Undo, row restored to original index.
+- Click "💾 Backup" → `Archive/<basename>_<date>.csv` appears (byte-identical to source); same-day repeat refused.
+- Verify csv saved correctly by reopening or checking mtime.
