Add CSV import functionality

- Use csv crate for robust CSV parsing (handles quoted fields, empty values, \r\n) - Extend --import command to auto-detect format by file extension (.csv or .json) - Reuse existing ImportPipeline and analyzer for field type detection - Categories detected automatically (string fields), measures for numeric fields - Updated help text and welcome screen to mention CSV support All 201 tests pass.
refactor: synthesize previous refactors

-# Beads - AI-Native Issue Tracking
-
-Welcome to Beads! This repository uses **Beads** for issue tracking - a modern, AI-native tool designed to live directly in your codebase alongside your code.
-
-## What is Beads?
-
-Beads is issue tracking that lives in your repo, making it perfect for AI coding agents and developers who want their issues close to their code. No web UI required - everything works through the CLI and integrates seamlessly with git.
-
-**Learn more:** [github.com/steveyegge/beads](https://github.com/steveyegge/beads)
-
-## Quick Start
-
-### Essential Commands
-
-```bash
-# Create new issues
-bd create "Add user authentication"
-
-# View all issues
-bd list
-
-# View issue details
-bd show <issue-id>
-
-# Update issue status
-bd update <issue-id> --claim
-bd update <issue-id> --status done
-
-# Sync with Dolt remote
-bd dolt push
-```
-
-### Working with Issues
-
-Issues in Beads are:
- **Git-native**: Stored in Dolt database with version control and branching
- **AI-friendly**: CLI-first design works perfectly with AI coding agents
- **Branch-aware**: Issues can follow your branch workflow
- **Always in sync**: Auto-syncs with your commits
-
-## Why Beads?
-
-✨ **AI-Native Design**
- Built specifically for AI-assisted development workflows
- CLI-first interface works seamlessly with AI coding agents
- No context switching to web UIs
-
-🚀 **Developer Focused**
- Issues live in your repo, right next to your code
- Works offline, syncs when you push
- Fast, lightweight, and stays out of your way
-
-🔧 **Git Integration**
- Automatic sync with git commits
- Branch-aware issue tracking
- Dolt-native three-way merge resolution
-

-# Beads Configuration File
-# This file configures default behavior for all bd commands in this repository
-# All settings can also be set via environment variables (BD_* prefix)
-# or overridden with command-line flags
-
-# Issue prefix for this repository (used by bd init)
-# If not set, bd init will auto-detect from directory name
-# Example: issue-prefix: "myproject" creates issues like "myproject-1", "myproject-2", etc.
-# issue-prefix: ""
-
-# Use no-db mode: JSONL-only, no Dolt database
-# When true, bd will use .beads/issues.jsonl as the source of truth
-# no-db: false
-
-# Enable JSON output by default
-# json: false
-
-# Feedback title formatting for mutating commands (create/update/close/dep/edit)
-# 0 = hide titles, N > 0 = truncate to N characters
-# output:
-#   title-length: 255
-
-# Default actor for audit trails (overridden by BEADS_ACTOR or --actor)
-# actor: ""
-
-# Export events (audit trail) to .beads/events.jsonl on each flush/sync
-# When enabled, new events are appended incrementally using a high-water mark.
-# Use 'bd export --events' to trigger manually regardless of this setting.
-# events-export: false
-
-# Multi-repo configuration (experimental - bd-307)
-# Allows hydrating from multiple repositories and routing writes to the correct database
-# repos:
-#   primary: "."  # Primary repo (where this database lives)
-#   additional:   # Additional repos to hydrate from (read-only)
-#     - ~/beads-planning  # Personal planning repo
-#     - ~/work-planning   # Work planning repo
-
-# JSONL backup (periodic export for off-machine recovery)
-# Auto-enabled when a git remote exists. Override explicitly:
-# backup:
-#   enabled: false     # Disable auto-backup entirely
-#   interval: 15m      # Minimum time between auto-exports
-#   git-push: false    # Disable git push (export locally only)
-#   git-repo: ""       # Separate git repo for backups (default: project repo)
-
-# Integration settings (access with 'bd config get/set')
-# These are stored in the database, not in this file:
-# - jira.url
-# - jira.project
-# - linear.url
-# - linear.api-key
-# - github.org
-# - github.repo

-# Agent Instructions
-
-This project uses **bd** (beads) for issue tracking. Run `bd prime` for full workflow context.
-
-## Quick Reference
-
-```bash
-bd ready              # Find available work
-bd show <id>          # View issue details
-bd update <id> --claim  # Claim work atomically
-bd close <id>         # Complete work
-bd dolt push          # Push beads data to remote
-```
-
-## Non-Interactive Shell Commands
-
-**ALWAYS use non-interactive flags** with file operations to avoid hanging on confirmation prompts.
-
-Shell commands like `cp`, `mv`, and `rm` may be aliased to include `-i` (interactive) mode on some systems, causing the agent to hang indefinitely waiting for y/n input.
-
-**Use these forms instead:**
-```bash
-# Force overwrite without prompting
-cp -f source dest           # NOT: cp source dest
-mv -f source dest           # NOT: mv source dest
-rm -f file                  # NOT: rm file
-
-# For recursive operations
-rm -rf directory            # NOT: rm -r directory
-cp -rf source dest          # NOT: cp -r source dest
-```
-
-**Other commands that may prompt:**
- `scp` - use `-o BatchMode=yes` for non-interactive
- `ssh` - use `-o BatchMode=yes` to fail instead of prompting
- `apt-get` - use `-y` flag
- `brew` - use `HOMEBREW_NO_AUTO_UPDATE=1` env var

-## Beads Issue Tracker
-
-This project uses **bd (beads)** for issue tracking. Run `bd prime` to see full workflow context and commands.
-
-### Quick Reference
-
-```bash
-bd ready              # Find available work
-bd show <id>          # View issue details
-bd update <id> --claim  # Claim work
-bd close <id>         # Complete work
-```
-
-### Rules
-
- Use `bd` for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
- Run `bd prime` for detailed command reference and session close protocol
- Use `bd remember` for persistent knowledge — do NOT use MEMORY.md files
-
-## Session Completion
-
-**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
-
-**MANDATORY WORKFLOW:**
-
-1. **File issues for remaining work** - Create issues for anything that needs follow-up
-2. **Run quality gates** (if code changed) - Tests, linters, builds
-3. **Update issue status** - Close finished work, update in-progress items
-4. **PUSH TO REMOTE** - This is MANDATORY:
-   ```bash
-   git pull --rebase
-   bd dolt push
-   git push
-   git status  # MUST show "up to date with origin"
-   ```
-5. **Clean up** - Clear stashes, prune remote branches
-6. **Verify** - All changes committed AND pushed
-7. **Hand off** - Provide context for next session
-
-**CRITICAL RULES:**
- Work is NOT complete until `git push` succeeds
- NEVER stop before pushing - that leaves work stranded locally
- NEVER say "ready to push when you are" - YOU must push
- If push fails, resolve and retry until it succeeds

 - Option<...> or Result<...> are fine but should not be present in the majority of the code.

- @context/repo-map.md is your "road map" for the repository. use it to reduce exploration and keep it updated.
- @context/design-principles.md is also important for keeping the repository consistent.

-# improvise
-
-*Terminal pivot-table modeling in the spirit of Lotus Improv — multidimensional cells, formulas over dimensions instead of cell addresses, and vim-style keybindings for reassigning axes on the fly.*
-
-![demo](docs/demo.gif)
-
-## Why this exists
-
-Lotus Improv (NeXT, 1991) separated data from its presentation: cells were
-addressed by named dimensions, not grid coordinates, and rearranging a view
-didn't break formulas. That idea never made it into mainstream tools. Excel
-pivot tables borrowed the visual rearrangement but kept cell-address formulas.
-Terminal data tools like sc-im and VisiData do different things well — sc-im is
-a traditional spreadsheet, VisiData is a data explorer — but neither offers the
-dimension-keyed data model that made Improv interesting. improvise is a small
-attempt to bring that model to a modern terminal, with a formula language that
-references category and item names, views that can be rearranged with a single
-keystroke, and a plain-text file format you can diff in git.
-
-See [docs/design-notes.md](docs/design-notes.md) for the original product
-vision and non-goals.
-
-## Quick start
-
-```sh
-nix build .
-./result/bin/improvise examples/demo.improv
-```
-
-Or import your own CSV:
-
-```sh
-./result/bin/improvise import path/to/data.csv
-```
-
-The included `examples/demo.improv` was generated from `examples/demo.csv`:
-
-```sh
-improvise import examples/demo.csv \
-  --no-wizard \
-  --category Region --category Product --category Customer \
-  --measure Revenue --measure Cost \
-  --time Date --extract Date:Month \
-  --axis Region:row --axis Product:row \
-  --axis Date_Month:column --axis Measure:column \
-  --axis Customer:page --axis Date:none \
-  --formula "Profit = Revenue - Cost" \
-  --name "Acme Sales Demo" \
-  -o examples/demo.improv
-```
-
-## Key bindings to try first
-
-| Key | Action |
-|-----|--------|
-| `T` | Enter tile mode — reassign category axes |
-| `[` / `]` | Cycle through page-axis items |
-| `>` | Drill into an aggregated cell |
-| `<` | Return from drill-down |
-| `F` | Open the formula panel |
-| `t` | Transpose rows and columns |
-| `?` / `F1` | Full key reference |
-| `:w` | Save |
-| `:q` | Quit |
-
-## Installation
-
-### With Nix (preferred)
-
-```sh
-nix build .
-# or install into your profile:
-nix profile install .
-```
-
-### From crates.io
-
-```sh
-cargo install improvise
-```
-
-### Prebuilt binaries
-
-See the [GitHub releases page](https://github.com/fiddlerwoaroof/improvise/releases)
-for prebuilt binaries (Linux x86_64, macOS Intel and Apple Silicon).
-
-## The data model
-
-Every cell lives at the intersection of named categories and items —
-`(Region=East, Measure=Revenue)` — not at a grid address like `B3`. A model
-can have up to 12 categories, each with an ordered list of items that can be
-organized into collapsible groups (e.g. months grouped into quarters).
-
-Formulas reference dimension names, not cell addresses:
-
-```
-Profit = Revenue - Cost
-Tax = Revenue * 0.08
-Margin = IF(Revenue > 0, Profit / Revenue, 0)
-BigDeal = Sum(Revenue WHERE Region = "West")
-```
-
-The formula language supports `+` `-` `*` `/` `^`, comparisons, `IF`, and
-aggregation functions (`Sum`, `Avg`, `Min`, `Max`, `Count`) with optional
-`WHERE` clauses. Formulas apply uniformly across all intersections — no
-copying, no dragging, no `$A$1` anchoring.
-
-## Views and axes
-
-A view assigns each category to one of four axes: **row**, **column**,
-**page** (slicer), or **hidden**. The grid layout is a pure function of
-`(Model, View)` → `GridLayout` — transposing is just swapping row and column
-assignments, and it happens in one keystroke (`t`). Page-axis categories act
-as filters: `[` and `]` cycle through items.
-
-Press `T` to enter tile mode, where each category appears as a tile in the
-tile bar. Move between tiles with `h`/`l`, then press `Space` to cycle axes
-or `r`/`c`/`p` to set one directly.
-
-Records mode (`R`) flips to a long-format view by assigning the virtual
-`_Index` and `_Dim` categories to row and column axes. Drill-down (`>`) on an
-aggregated cell captures a snapshot; edits accumulate in a staging area and
-commit atomically on exit.
-
-## File format
-
-Models persist to a plain-text `.improv` format that reads like markdown and
-diffs cleanly in git:
-
-```
-# Sales 2025
-
-## Category: Region
- North
- South
- East [Coastal]
- West [Coastal]
-> Coastal
-
-## Category: Measure
- Revenue
- Cost
- Profit
-
-## Formulas
- Profit = Revenue - Cost [Measure]
-
-## Data
-Region=East, Measure=Revenue = 1200
-Region=East, Measure=Cost = 800
-
-## View: Default (active)
-Region: row
-Measure: column
-format: ,.2f
-```
-
-Gzip-compressed `.improv.gz` is also supported. Legacy JSON is auto-detected
-for backward compatibility.
-
-## Import and scripting
-
-The import wizard analyzes CSV columns and proposes each as a category
-(string-valued), measure (numeric), time dimension (date-like, with optional
-year/month/quarter extraction), or skip. Multiple CSVs merge automatically
-with a synthetic "File" category.
-
-All model mutations go through a typed command registry, so the same
-operations that back the TUI work headless:
-
-```sh
-# single commands
-improvise cmd 'add-cat Region' 'add-item Region East' -f model.improv
-
-# script file (one command per line, # comments)
-improvise script setup.txt -f model.improv
-```
-
-## What's interesting about the architecture
-
-All user actions flow through a two-phase command/effect pipeline. Commands
-are pure functions: they receive an immutable `CmdContext` (model, layout,
-cursor position, mode) and return a list of effects. Effects are the only
-things that mutate app state, and each one is a small, debuggable struct.
-This means commands are testable without a terminal, effects can be logged or
-replayed, and the 40+ commands and 50+ effect types are all polymorphic —
-dispatched through trait objects and a registry, not a central match block.
-The keybinding system gives each of the 14 modes its own keymap, with
-Emacs-style prefix keys for multi-stroke sequences.
-
-## Expectations
-
-improvise is a personal project I built for my own use. I'm sharing it because
-other people might find it useful, but I can't promise active maintenance or
-feature development. Issues and PRs are welcome but may not get a fast
-response. If you want to build on it, fork away.

+# Improvise — Multi-Dimensional Data Modeling Terminal Application
+
+## Context
+
+Traditional spreadsheets conflate data, formulas, and presentation into a single flat grid addressed by opaque
+cell references (A1, B7). This makes models fragile, hard to audit, and impossible to rearrange without
+rewriting formulas. We are building a terminal application that treats data as a multi-dimensional,
+semantically labeled structure — separating data, computation, and views into independent layers. The result
+is a tool where formulas reference meaningful names, views can be rearranged instantly, and the same dataset
+can be explored from multiple perspectives simultaneously.
+
+The application compiles to a single static binary (`x86_64-unknown-linux-musl`) and provides a rich TUI
+experience.
+
+---
+
+## 1. Core Data Model
+
+### 1.1 Categories and Items
+- Data is organized into **categories** (dimensions) and **items** (members of a dimension).
+  - Example: Category "Region" contains items "North", "South", "East", "West".
+  - Example: Category "Time" contains items "Q1", "Q2", "Q3", "Q4".
+- Items within a category can be organized into **groups** forming a hierarchy.
+  - Example: Items "Jan", "Feb", "Mar" grouped under "Q1"; quarters grouped under "2025".
+- Groups are collapsible/expandable for drill-down.
+- A model supports up to **12 categories**.
+
+### 1.2 Data Cells
+- Each data cell is identified by the intersection of one item from each active category — not by grid coordinates.
+- Cells hold numeric values, text, or empty/null.
+- The underlying storage is a sparse multi-dimensional array (`HashMap<CellKey, CellValue>`).
+
+### 1.3 Models
+- A **model** is the top-level container: it holds all categories, items, groups, data cells, formulas, and views.
+- Models are saved to and loaded from a single `.improv` file (JSON format).
+
+---
+
+## 2. Formula System
+
+### 2.1 Named Formulas
+- Formulas reference categories and items by name, not by cell address.
+  - Example: `Profit = Revenue - Cost`
+  - Example: `Tax = Revenue * 0.08`
+  - Example: `Margin = Profit / Revenue`
+- A formula applies uniformly across all intersections of the referenced categories. No copying or dragging.
+
+### 2.2 Formula Panel
+- Formulas are defined in a **dedicated formula panel**, separate from the data grid.
+- All formulas are visible in one place for easy auditing.
+- Formulas cannot be accidentally overwritten by data entry.
+
+### 2.3 Scoped Formulas (WHERE clause)
+- A formula can be scoped to a subset of items:
+  - Example: `Discount = 0.10 * Price WHERE Region = "West"`
+
+### 2.4 Aggregation
+- Built-in aggregation functions: `SUM`, `AVG`, `MIN`, `MAX`, `COUNT`.
+
+### 2.5 Formula Language
+- Expression-based (not Turing-complete).
+- Operators: `+`, `-`, `*`, `/`, `^`, unary `-`.
+- Comparisons: `=`, `!=`, `<`, `>`, `<=`, `>=`.
+- Conditionals: `IF(condition, then, else)`.
+- `WHERE` clause for filtering: `SUM(Sales WHERE Region = "East")`.
+- Parentheses for grouping.
+- Literal numbers and quoted strings.
+
+---
+
+## 3. View System
+
+### 3.1 Views as First-Class Objects
+- A **view** is a named configuration specifying:
+  - Which categories are assigned to **rows**, **columns**, and **pages** (filters/slicers).
+  - Which items/groups are visible vs. hidden.
+  - Sort order (future).
+  - Number formatting.
+- Multiple views can exist per model. Each is independent.
+- Editing data in any view updates the underlying model; all other views reflect the change.
+
+### 3.2 Category Tiles
+- Each category is represented as a **tile** displayed in the tile bar.
+- The user can move tiles between row, column, and page axes to instantly pivot/rearrange the view.
+- Moving a tile triggers an instant recalculation and re-render of the grid.
+
+### 3.3 Page Axis (Slicing)
+- Categories assigned to the page axis act as filters.
+- The user selects a single item from a paged category using `[` and `]`.
+
+### 3.4 Collapsing and Expanding
+- Groups can be collapsed/expanded per-view (future: keyboard shortcut in grid).
+
+---
+
+## 4. JSON Import Wizard
+
+### 4.1 Purpose
+- Users can import arbitrary JSON files to bootstrap a model.
+
+### 4.2 Wizard Flow (interactive TUI)
+
+**Step 1: Preview** — Structural summary of the JSON.
+
+**Step 2: Select Array Path** — If the JSON is not a flat array, the user selects which key path contains the primary record array.
+
+**Step 3: Review Proposals** — Fields are analyzed and proposed as:
+  - Category (small number of distinct string values)
+  - Measure (numeric)
+  - Time Category (date-like strings)
+  - Label/Identifier (skip)
+
+**Step 4: Name the Model** — User names the model and confirms.
+
+### 4.3 Headless Import
+```
+improvise --cmd '{"op":"ImportJson","path":"data.json"}'
+```
+
+---
+
+## 5. Terminal UI
+
+### 5.1 Layout

+
+---
+
+## 8. Technology
+
+| Concern | Choice |

+| TUI | [Ratatui](https://github.com/ratatui-org/ratatui) + Crossterm |
+| Serialization | `serde` + `serde_json` |
+| Static binary | `x86_64-unknown-linux-musl` via `musl-gcc` |
+| Dev environment | Nix flake with `rust-overlay` |

+
+---
+
+## 9. Non-Goals (v1)
+
+- Scripting/macro language beyond the formula system.
+- Collaborative/multi-user editing.

-# Improvise Design Principles
-
-## 1. Functional-First Architecture
-
-### Commands Are Pure, Effects Are Side-Effectful
-
-Every user action flows through a two-phase pipeline:
-
-1. **Command** (`Cmd` trait) — reads immutable context, returns a list of effects.
-   The `CmdContext` is a read-only snapshot: model, layout, mode, cursor position.
-   Commands never touch `&mut App`. All decision logic is pure.
-
-2. **Effect** (`Effect` trait) — a small struct with an `apply(&self, app: &mut App)` method.
-   Each effect is one discrete, debuggable state change. The app applies them in order.
-
-This separation means:
- Commands are testable without a terminal or an `App` instance.
- Effects can be logged, replayed, or composed.
- The only place `App` is mutated is inside `Effect::apply`.
-
-### Prefer Transformations to Mutation
-
-Where possible, build new values rather than mutating in place:
- `CellKey::with(cat, item)` returns a new key with an added/replaced coordinate.
- `CellKey::without(cat)` returns a new key with a coordinate removed.
- Viewport positioning is computed as a pure function (`viewport_effects`) that
-  returns a `Vec<Effect>`, not a method that pokes at scroll offsets directly.
-
-### Compose Small Pieces
-
-Commands compose via `Binding::Sequence` — a keymap entry can chain multiple
-commands, each contributing effects independently. The `o` key (add row + begin
-editing) is two commands composed at the binding level, not a monolithic handler.
-
---
-
-## 2. Polymorphism Over Conditionals
-
-### Dispatch Through Traits and Registries, Not Match Blocks
-
- **Commands**: 40+ types each implement `Cmd`, organized by concern across
-  submodules in `command/cmd/` (navigation, cell, commit, grid, mode, panel,
-  search, text_buffer, tile, effect_cmds). A `CmdRegistry` maps names to
-  constructor closures. Dispatching a key press looks up the binding, resolves
-  the command name through the registry, and calls `execute`. No central
-  `match command_name { ... }` block.
-
- **Effects**: 50+ types each implement `Effect`. Collected into a `Vec<Box<dyn Effect>>`
-  and applied in order. No `match effect_kind { ... }`.
-
- **Keymaps**: Each mode has its own `Keymap` (a `HashMap<KeyPattern, Binding>`).
-  Mode dispatch is one table lookup, not a nested `match (mode, key)`.
-
-### Use Enums to Make Invalid States Unrepresentable
-
- `BinOp` is an enum (`Add | Sub | Mul | ...`), not a string. Invalid operators
-  are caught at parse time, not silently ignored at eval time.
-
- `Axis` is `Row | Column | Page | None`. A category is on exactly one axis.
-  Cycling is a four-state rotation — no boolean flags, no "row_or_column" ambiguity.
-
- `Binding` is `Cmd | Prefix | Sequence`. The keymap lookup returns one of these
-  three shapes; dispatch pattern-matches exhaustively.
-
- `CategoryKind` is `Regular | VirtualIndex | VirtualDim | VirtualMeasure | Label`.
-  Business rules (e.g., the 12-category limit counts only `Regular`) are
-  enforced by matching on the enum, not by checking name prefixes. Virtual
-  categories (`_Index`, `_Dim`, `_Measure`) always exist: `_Index` and `_Dim`
-  support drill-down/records mode; `_Measure` holds numeric data fields and
-  formula targets (added automatically by `add_formula`). Use
-  `Model::regular_category_names()` when selecting a default category for
-  prompts or other user-visible choices.
-
-### When You Add a Variant, the Compiler Finds Every Call Site
-
-Prefer exhaustive `match` over `if let` or `_ =>` wildcards. When a new `Axis`
-variant or `AppMode` is added, non-exhaustive matches produce compile errors
-that guide you to every place that needs updating.
-
---
-
-## 3. Correctness by Construction
-
-### Canonical Forms Prevent Equivalence Bugs
-
-`CellKey::new()` sorts coordinates by category name. Two keys that name the same
-intersection but in different order are identical after construction. Equality,
-hashing, and storage all work correctly without callers needing to remember to
-sort. Property tests verify this invariant.
-
-### Smart Constructors Enforce Invariants
-
- `CellKey::new()` is the only way to build a key — it always sorts.
- `Category::add_item()` deduplicates by name and auto-assigns IDs via a private
-  counter. External code cannot fabricate an `ItemId`.
- `Model::add_category()` checks the 12-category limit before insertion.
- `Formula::new()` takes all required fields; there is no default/empty formula
-  to accidentally leave half-initialized.
-
-### Type-Safe Identifiers
-
-`CategoryId` and `ItemId` are typed aliases. While they are `usize` underneath,
-using named types signals intent and prevents accidentally passing an item count
-where an item ID is expected.
-
-### Symbol Interning for Data Integrity
-
-`DataStore` interns category and item names into `Symbol` values (small copyable
-handles). This means:
- String comparison is integer comparison — fast and allocation-free.
- A secondary index maps `(Symbol, Symbol)` pairs to cell sets, enabling O(1)
-  lookups for aggregation queries.
- Symbols can only be created through the `SymbolTable`, so misspelled names
-  produce a distinct symbol rather than silently matching a wrong cell.
-
-### Parse-Time Validation
-
-Formulas are parsed into a typed AST (`Expr` enum) at entry time. If the syntax
-is invalid, the user gets an error immediately. The evaluator only sees
-well-formed trees — it does not need to handle malformed input.
-
-### Grammar-Defined File Format
-
-The `.improv` file format is defined by a PEG grammar (`persistence/improv.pest`)
-and parsed by pest. The grammar is the single source of truth — the parser is a
-tree-walker over the grammar's parse tree, not an ad-hoc line scanner. This means:
-
- Adding a new format feature means updating the grammar first, then the walker.
- The grammar can be read as a specification independent of the Rust code.
- A grammar-walking test generator reads the grammar AST at test time (via
-  `pest_meta`) and produces random valid files, ensuring the parser accepts
-  everything the grammar describes.
-
-### CL-Style Pipe Quoting for Names
-
-Names in the `.improv` format use CL-style `|...|` pipe quoting. A name is bare
-if it matches `[A-Za-z_][A-Za-z0-9_-]*`; everything else must be pipe-quoted.
-Escapes inside pipes: `\|` (literal pipe), `\\` (backslash), `\n` (newline).
-This convention is shared between the `.improv` persistence format and the
-formula parser's identifier syntax.
-
-### Formula Tokenizer: Identifiers and Quoting
-
-**Bare identifiers** support multi-word names (e.g., `Total Revenue`) by
-allowing spaces when followed by non-operator, non-keyword characters. Keywords
-(`WHERE`, `SUM`, `AVG`, `MIN`, `MAX`, `COUNT`, `IF`) act as token boundaries.
-
-**Pipe-quoted identifiers** (`|...|`) allow any characters — including spaces,
-keywords, and operators — inside the delimiters. Use pipes when a category or
-item name collides with a keyword or contains special characters:
-
-```
-|WHERE|             — category named "WHERE"
-|Revenue (USD)|     — name with parens
-|Cost + Tax|        — name with operator chars
-SUM(|Net Revenue| WHERE |Region Name| = |East Coast|)
-```
-
-Pipes produce `Token::Ident` (same as bare identifiers), so they work
-everywhere an identifier is expected: expressions, aggregate arguments, WHERE
-clause category names and filter values. Double-quoted strings (`"..."`)
-remain `Token::Str` and are used only for WHERE filter values in the
-`split_where` pre-parse step.

-## 4. Separation of Concerns
-
-### Four Layers
-
-| Layer | Directory | Responsibility |
-|-------|-----------|----------------|
-| **Model** | `src/model/` | Categories, items, groups, cell data, formulas. Pure data, no rendering. |
-| **View** | `src/view/` | Axis assignments, page selection, hidden items, layout computation. Derived from model. |
-| **Command / Effect** | `src/command/`, `src/ui/effect.rs` | Intent (commands) and state mutation (effects). Bridges user input to model changes. |
-| **Rendering** | `src/draw.rs`, `src/ui/` | Terminal drawing. Reads model + view, writes pixels. No mutation. |
-
-### Formulas Are Data, Not Code
-
-A formula is a serializable struct: raw text, target name, category, AST, optional
-filter. It is stored in the model alongside regular data. The evaluator walks the
-AST at read time. Formulas never become closures or runtime-generated code.
-
-### Formula Evaluation Is Fixed-Point
-
-`recompute_formulas(none_cats)` iterates formula evaluation until values
-stabilize. Each pass evaluates all formula cells using the current cache
-(for formula-derived values) and raw data aggregation (for data values).
-This avoids recursive evaluation through `evaluate_aggregated` and
-naturally handles chained formulas (`Margin = Profit / Revenue` where
-`Profit = Revenue - Cost`). Circular references converge to
-`CellValue::Error("circular")` after `MAX_EVAL_DEPTH` iterations.
-
-### Display Rounding Is View-Only
-
-Number formatting (`format_f64`) rounds for display. Formula evaluation always
-operates on full `f64` precision. The rounding function is only called in
-rendering paths — never in `eval_formula` or aggregation.
-
-### Drill State Isolates Edits
-
-When editing aggregated (drill-down) cells, a `DrillState` snapshot freezes the
-current cell set. Pending edits accumulate in a staging map. On commit,
-`ApplyAndClearDrill` writes them all atomically. On cancel, the snapshot is
-discarded. No partial writes reach the model.
-
---
-
-## 5. Guidelines for New Code
-
- **Add a command, not a special case.** If you need new behavior on a keypress,
-  implement `Cmd`, register it, and bind it in the keymap. Do not add an
-  `if key == 'x'` branch inside `handle_key`.
-
- **Return effects, do not mutate.** Your command's `execute` receives `&CmdContext`
-  (immutable). Produce a `Vec<Box<dyn Effect>>`. If you need a new kind of state
-  change, create a new `Effect` struct.
-
- **Use the type system.** If a value can only be one of N things, make it an enum.
-  If an invariant must hold, enforce it in the constructor. If a field is
-  optional, use `Option` — do not use sentinel values.
-
- **Test the logic, not the wiring.** Commands are pure functions of context;
-  test them by building a `CmdContext` and asserting on the returned effects.
-  You do not need a terminal.
-
- **Keep `Option`/`Result`/`Box` at the boundaries.** Core logic should work with
-  concrete values. Wrap in `Option` at the edges (parsing, lookup, I/O) and
-  unwrap early. Do not thread `Option` through deep call chains.
-
---
-
-## 6. Testing
-
-### Coverage and ambition
-
-Aim for **~80% line and branch coverage** on logic code. This is a quality floor —
-go higher where the code is tricky or load-bearing, but don't pad coverage by
-testing trivial getters or chasing 100% on rendering widgets. The test suite
-should remain fast (under 2 seconds). Slow tests erode the habit of running them.
-
-### Demonstrate bugs before fixing them
-
-Write a test that **fails on the current code** before writing the fix. Prefer a
-small unit test targeting the broken function over an end-to-end test. After the
-fix, the test stays as a regression guard. Document the bug in the test's
-doc-comment (see `model/types.rs` → `formula_tests` for examples).
-
-### Use property tests judiciously
-
-Property tests (`proptest`) are for **invariants that must hold across all
-inputs** — not a replacement for example-based tests. Good candidates:
-
- Structural invariants: CellKey is always sorted, each category lives on exactly
-  one axis, toggle-collapse is involutive, hide/show roundtrips.
- Serialization roundtrips: save/load identity.
- Determinism: `evaluate` returns the same result for the same inputs.
-
-Keep case counts at the default (256). Don't crank them to thousands — if a
-property needs more cases to feel safe, constrain the input space with better
-strategies rather than brute-forcing. Property tests that take hundreds of
-milliseconds each are a sign something is wrong.
-
-### What to test
-
- **Model, formula, view**: the core logic. Unit tests for each operation and
-  edge case. Property tests for invariants. These are the highest-value tests.
- **Commands**: build a `CmdContext`, call `execute`, assert on the returned
-  effects. Pure functions — no terminal needed. Tests are colocated in each
-  command submodule (`command/cmd/<module>.rs` → `mod tests`), with shared
-  test helpers in `command/cmd/mod.rs::test_helpers`.
- **Persistence**: round-trip tests (`save → load → save` produces identical
-  output) plus grammar-driven property tests. The generator walks the pest
-  grammar AST to produce random valid files; proptests verify
-  `parse(generate())` succeeds and `parse(format(parse(generate())))` is
-  stable. Cover groups, formulas, views, hidden items, pipe quoting edges.
- **Format**: boundary cases for comma placement, rounding, negative numbers.
- **Import**: field classification heuristics, CSV quoting, multi-file merge.
-
-### What not to test
-
- Ratatui `Widget::render` implementations — pure drawing code that changes
-  often. Test the data they consume (layout, cat_tree, format) instead.
- Trivial data definitions (`ast.rs`, `axis.rs`).
- Module re-export files.
-
-### Test the property, not the implementation
-
-A test like "calling `set_axis(cat, Row)` sets the internal map entry to `Row`"
-is brittle — it mirrors the implementation and breaks if the storage changes.
-Instead test the observable contract: "after `set_axis(cat, Row)`,
-`axis_of(cat)` returns `Row` and `categories_on(Row)` includes `cat`." This
-style survives refactoring and catches real bugs.

-# improvise — launch preparation plan
-
-You are working in the `improvise` repository, a Rust terminal application that implements a Lotus Improv-style pivot-table modeling tool. Cells are keyed by sets of `(category, item)` coordinates rather than 2D grid addresses; views assign categories to row/column/page axes; formulas reference dimension names rather than cell addresses. The application is built with `ratatui` + `crossterm`, persists models in a markdown-based `.improv` format (with optional gzip), and supports both an interactive TUI and a headless command/script mode through a unified registry.
-
-Your job is to prepare this repository for a public Show HN launch. The bar is "ready for strangers to install and try in 60 seconds," not "feature-complete." Do tasks in the order given. Do not start a later phase before earlier phases are complete. Do not add features, refactor warts, or restructure modules — those are explicitly out of scope and listed at the end.
-
-The target audience is developers who use vim, who have opinions about data modeling, and who would understand a Lotus Improv reference. The pitch positions improvise as a pivot-table modeling tool, not "a spreadsheet in a terminal" — that framing competes with sc-im and VisiData and loses.
-
-The development environment is Nix-based (the repo has a `flake.nix`). The user does not have Homebrew installed and will not install it. All tooling must be available through Nix, and any process that needs new tools must be codified as additions to `flake.nix` so the user can reach them via `nix develop` or `nix run`. Do not suggest `brew install` anywhere.
-
---
-
-## Phase 1 — Repository hygiene
-
-Goal: raise the quality floor of what a stranger sees when they land on the repo. Roughly 90 minutes of work.
-
-### 1.1 Audit and remove or update `context/SPEC.md`
-
-Read `context/SPEC.md` and compare it against the actual code. The spec is likely stale: it may describe a JSON import wizard when the real wizard handles CSV, and it may describe JSON persistence when the real format is markdown (look at `src/persistence/mod.rs` to confirm). It may also list commands that no longer exist in the registry.
-
-If the spec contradicts the code in significant ways, delete it. If you want to preserve design intent, move salvageable conceptual content to `docs/design-notes.md` with a header that reads:
-
-> **Note:** This document captures design intent and may not reflect the current implementation. The README and source code are authoritative.
-
-Do not try to bring the spec back into sync with the code — that is not worth the effort for a personal project, and a stale spec is worse than no spec.
-
-### 1.2 Fix `Cargo.toml` metadata
-
-The current `[package]` section is missing fields that crates.io and `cargo dist` need. Update it to include:
-
- `description` — replace any generic placeholder with: `"Terminal pivot-table modeling in the spirit of Lotus Improv"`
- `repository` — ask the user for the GitHub URL if you don't already know it; otherwise leave a `TODO` comment and flag it
- `homepage` — same URL as `repository`
- `documentation` — same URL as `repository` for now
- `readme = "README.md"`
- `keywords = ["tui", "pivot", "spreadsheet", "data", "improv"]` (max 5 keywords, each ≤20 chars)
- `categories = ["command-line-utilities", "visualization"]`
- `license` — confirm this is set; if not, ask the user
-
-Preserve all existing fields and dependency entries.
-
-### 1.3 Verify publish-readiness
-
-Run `cargo publish --dry-run` from inside `nix develop`. Fix any errors or warnings. Common issues: missing license file, files too large to publish, dependencies with incompatible versions. Do not actually publish — that happens in Phase 3.
-
-### 1.4 Audit CSV quote handling
-
-Look at `src/import/csv_parser.rs` (or wherever CSV parsing lives). Verify that it correctly handles RFC 4180 quoted fields: fields enclosed in double quotes, embedded commas inside quoted fields, and escaped quotes (`""` inside a quoted field).
-
-If the parser is using the `csv` crate from `Cargo.toml`, this should be handled correctly by default — verify that the code is actually using it and not doing manual `split(',')` anywhere. If there are any places that do manual splitting or fragile quote handling, fix them by routing through the `csv` crate. Add a unit test that round-trips a CSV row with `"O'Reilly, Inc."` (embedded comma) and `"She said ""hi"""` (embedded escaped quotes).
-
-If the parser is fundamentally broken in ways that can't be fixed quickly, do not block on this. Add a one-line note to the README under a "Known limitations" section: "CSV files with unusual quoting may not parse correctly; PRs welcome."
-
-### 1.5 Create `examples/demo.improv` and `examples/demo.csv`
-
-Create two synthetic example files with obviously-fake data. These exist so a new user can run `improvise examples/demo.improv` and immediately see a working pivot, or `improvise --import examples/demo.csv` and walk through the wizard.
-
-**`examples/demo.csv`** should contain ~30-50 rows with columns like:
- `Date` (mix of dates across at least 2 quarters of one year)
- `Region` (3-4 values: North, South, East, West)
- `Product` (3-4 values: Widget, Gadget, Sprocket, Doohickey)
- `Customer` (5-8 fake company names: Acme Corp, Globex, Initech, Umbrella, Soylent, etc.)
- `Revenue` (round numbers, 100-10000)
- `Cost` (round numbers, less than Revenue)
-
-**`examples/demo.improv`** should be the result of importing `demo.csv` through the tool, then manually saving. To create it: build the tool, run the import on `demo.csv`, optionally pivot it into an interesting default view (e.g., Region on rows, Date_Quarter on columns, Product on page axis), add a sample formula like `Profit = Revenue - Cost` if the formula system supports it, save as `examples/demo.improv`, and commit both files.
-
-If you cannot determine the exact format syntax, look at existing test fixtures or run the tool's save path on a small in-memory model to generate one.
-
-The data must be obviously synthetic. Do not copy data from any other file in the repo. Do not use any real-looking names, real amounts, or anything that looks like it might be from a real bank export.
-
---
-
-## Phase 2 — README and demo artifacts
-
-This is the main weekend's work. The README is 80% of the launch. The demo artifacts are the other 20%. Nothing in Phase 3 or 4 matters if Phase 2 is weak.
-
-### 2.1 Add Nix tooling for asciinema and VHS
-
-The user does not have Homebrew. Both asciinema (terminal session recording) and VHS (Charmbracelet's terminal-to-GIF tool, package name `vhs` in nixpkgs) need to be available through Nix.
-
-Modify `flake.nix` to add `pkgs.asciinema` and `pkgs.vhs` to the dev shell's `nativeBuildInputs`. Both packages exist in nixpkgs unstable; verify before adding. If `vhs` requires additional runtime dependencies (it uses `ttyd` and `ffmpeg` internally), add those too — check the nixpkgs `vhs` derivation to see what's already bundled.
-
-After modifying the flake, verify that `nix develop --command asciinema --version` and `nix develop --command vhs --version` both work.
-
-While you're in the flake, also add:
- `pkgs.cargo-dist` for the release tooling in Phase 3 (if it's packaged in nixpkgs; if not, fall back to running it via `cargo install` inside the dev shell and note this in a comment)
- A `nix run` app or shell alias for the demo recording workflow (see 2.4)
-
-### 2.2 Write the README
-
-Replace any existing `README.md` with a new one structured as follows. Aim for under 250 lines total.
-
-**Section order (do not deviate):**
-
-1. **Title** — `# improvise`
-
-2. **One-sentence pitch** — italicized, immediately under the title:
-   > *Terminal pivot-table modeling in the spirit of Lotus Improv — multidimensional cells, formulas over dimensions instead of cell addresses, and vim-style keybindings for reassigning axes on the fly.*
-
-3. **Inline animated demo** — `![demo](docs/demo.gif)` (the GIF generated in step 2.5). This must be near the top so it shows in HN previews and the GitHub repo card.
-
-4. **Why this exists** — exactly one paragraph. Explain the Improv data/view separation and why no terminal tool currently does it. Reference Lotus Improv (NeXT, 1991) by name. Briefly note that Excel pivot tables took the visual idea but not the formula model. Do not bash other tools — name sc-im and VisiData neutrally as adjacent-but-different.
-
-5. **Quick start** — three code blocks:
-   ```
-   nix develop
-   cargo build --release
-   ./target/release/improvise examples/demo.improv
-   ```
-   Followed by a one-line "or import your own CSV":
-   ```
-   ./target/release/improvise --import path/to/data.csv
-   ```
-
-6. **Key bindings to try first** — short list, not a complete reference. `T` for tile mode (reassign axes), `[` `]` for page axis cycling, `>` to drill into a cell, `<` to return, `F` for formula panel, `:w` to save, `:q` to quit, `?` or `F1` for full help.
-
-7. **Installation** — three subsections:
-   - **From source with Nix** (preferred): `nix develop` then `cargo build --release`, then optionally `cargo install --path .`
-   - **From crates.io**: `cargo install improvise` (will be valid after Phase 3)
-   - **Prebuilt binaries**: link to GitHub releases page (will be populated after Phase 3)
-   
-   Do not mention Homebrew. Do not mention `apt`, `dnf`, or other distro package managers.
-
-8. **What's interesting about the codebase** — 10-15 lines, prose, no bullets. Cover: the multidimensional data model with categories instead of grid coordinates; the view layer as a pure function from `(Model, View)` to `GridLayout`; records mode as just another axis assignment; the command/effect architecture that lets the same registry serve both interactive dispatch and headless scripts; the markdown `.improv` persistence format that's human-readable and git-diffable.
-
-9. **Expectations** — mandatory disclaimer paragraph, exact wording:
-   > improvise is a personal project I built for my own use. I'm sharing it because other people might find it useful, but I can't promise active maintenance or feature development. Issues and PRs are welcome but may not get a fast response. If you want to build on it, fork away.
-
-10. **License** — one line.
-
-Do not add: a table of contents, badges (build status, version, license badges, etc.), a contributing guide, a code of conduct, an "inspired by" gratitude section. These are noise for a personal project launch.
-
-### 2.3 Create `docs/demo.tape` and generate `docs/demo.gif`
-
-VHS is scripted: you write a `.tape` file describing keystrokes and timing, and VHS produces a GIF. This GIF goes inline in the README and is the single highest-leverage artifact in the launch — it's what shows up in HN preview cards and Google search results.
-
-Create `docs/demo.tape` that scripts a ~20-second flow showing the pivot reassignment killer demo. Rough script structure (consult VHS docs for exact syntax):
-
-```
-Output docs/demo.gif
-Set FontSize 14
-Set Width 1000
-Set Height 600
-Set Theme "Dracula"
-
-Type "improvise examples/demo.improv"
-Enter
-Sleep 1500ms
-
-# Show initial pivot
-Sleep 1s
-
-# Enter tile mode and reassign an axis
-Type "T"
-Sleep 800ms
-# (whatever keystrokes reassign Region from rows to columns)
-Sleep 1500ms
-
-# Show the new pivot
-Sleep 1s
-
-# Reassign again to demonstrate the speed
-# (more keystrokes)
-Sleep 1500ms
-
-# Exit
-Type ":q"
-Enter
-```
-
-Generate the GIF by running `nix develop --command vhs docs/demo.tape`. Iterate on the script until the GIF is under 5MB, the timing is readable (not too fast, not too slow), and the key beats are clear: start in pivot view → press T → axis reassigns → press T again → axis reassigns again. The viewer should be able to understand "this tool re-pivots data with one keystroke" without any narration.
-
-### 2.4 Record asciinema casts
-
-Asciinema produces `.cast` files that the asciinema-player JS widget can replay in a browser, with selectable text and pixel-perfect terminal rendering. These will be embedded in the GitHub Pages landing page in Phase 4.
-
-Before recording, set the terminal to exactly 100 columns by 30 rows: `stty cols 100 rows 30` (or resize the terminal window manually if `stty` doesn't take). This matters because the asciinema player renders at the recorded dimensions and a wrong size will look broken on the landing page.
-
-Record four casts under `docs/casts/`:
-
- **`docs/casts/import.cast`** — start with `improvise` (no args, empty model), trigger CSV import for `examples/demo.csv`, walk through the wizard accepting defaults, end in pivot view.
- **`docs/casts/pivot.cast`** — start from `improvise examples/demo.improv`, demonstrate axis reassignment with `T`. This is the same flow as the README GIF but longer and more complete. Show 2-3 different pivots.
- **`docs/casts/drill.cast`** — from a pivot view, press `>` to drill into an aggregated cell, show the records view, demonstrate that you can edit a record, press `<` to return.
- **`docs/casts/formulas.cast`** — from a pivot view, open the formula panel with `F`, add `Profit = Revenue - Cost`, show it appearing across the pivot.
-
-Record each with `nix develop --command asciinema rec -i 2 docs/casts/<name>.cast`. The `-i 2` flag caps idle gaps at 2 seconds, which prevents long pauses from making the playback feel dead. Each cast should be under 60 seconds.
-
-If a take has flubs, delete it and re-record. Do not try to edit the JSON cast files manually.
-
-Add a `nix run` app to the flake or a shell script in `scripts/record-demo.sh` that wraps the recording workflow with the right `stty` setup, so the user can re-record consistently in the future without remembering the exact incantation.
-
-### 2.5 Verify all artifacts exist and are committed
-
-Before moving to Phase 3, confirm:
- `README.md` exists with all 10 sections
- `docs/demo.gif` exists, is referenced from the README, and is under 5MB
- `docs/demo.tape` exists and regenerates the GIF when run through VHS
- `docs/casts/import.cast`, `pivot.cast`, `drill.cast`, `formulas.cast` all exist
- `examples/demo.csv` and `examples/demo.improv` exist and contain only synthetic data
- `flake.nix` includes `asciinema`, `vhs`, and `cargo-dist` (or a fallback for `cargo-dist`)
- `nix develop` succeeds and all the tools above are on PATH
-
---
-
-## Phase 3 — Distribution
-
-### 3.1 Configure `cargo dist`
-
-`cargo dist` generates a GitHub Actions workflow that produces release tarballs and installer scripts when you push a version tag. Run `nix develop --command cargo dist init` and configure for these targets:
-
- `x86_64-unknown-linux-gnu`
- `aarch64-apple-darwin`
- `x86_64-apple-darwin`
-
-Skip Windows. Skip musl unless `cargo dist init` strongly recommends it — the existing flake doesn't build for musl and adding that complication is out of scope.
-
-Commit the generated `.github/workflows/release.yml` and the additions to `Cargo.toml`. Test the workflow by tagging `v0.1.0-rc1` and pushing the tag to a branch — verify the release builds successfully on GitHub Actions before doing a real release. Delete the rc tag afterward.
-
-### 3.2 Publish to crates.io
-
-After `cargo publish --dry-run` is clean (from step 1.3) and the user confirms they're ready, run `nix develop --command cargo publish`. Verify the crate appears at `https://crates.io/crates/improvise` and that `cargo install improvise` works on a clean machine (or in a fresh `nix shell --packages cargo`).
-
-### 3.3 Tag the v0.1.0 release
-
-Create a git tag `v0.1.0`, push it, and verify the `cargo dist` workflow produces release artifacts. Update the README's "Prebuilt binaries" link to point at the actual release.
-
---
-
-## Phase 4 — Landing page (optional but recommended)
-
-### 4.1 Create `docs/index.html`
-
-Vanilla HTML, single file, under 200 lines. No framework, no build step. Dark background, monospace headings to match the terminal aesthetic. Embed the asciinema-player from jsdelivr CDN (`https://cdn.jsdelivr.net/npm/asciinema-player@3/dist/bundle/`) and reference the four `.cast` files from `docs/casts/`.
-
-Section structure: title and one-line tagline → "Reassign axes on the fly" with the pivot cast → "Drill into aggregated cells" with the drill cast → "Formulas over dimensions" with the formulas cast → "Import a CSV" with the import cast → "Get it" with the install commands and a GitHub link.
-
-Each cast should be embedded with `AsciinemaPlayer.create()` configured with `rows: 30, cols: 100, theme: 'monokai', autoPlay: false, loop: true`.
-
-### 4.2 Enable GitHub Pages
-
-In the GitHub repo settings, enable Pages with source set to the `main` branch and folder set to `/docs`. Verify the site is live at `https://<user>.github.io/improvise/` within a few minutes of pushing.
-
---
-
-## Phase 5 — Buffer
-
-The second weekend (or the second half of the first weekend) is reserved for whatever was missed in Phases 1-4. Do not use it to add features. Do not use it to fix the issues listed in "Out of scope" below. If everything is done early, stop.
-
---
-
-## Out of scope — do not do these before launch
-
-The following are real issues that have been identified but are explicitly not launch-blocking. Do not start any of them as part of this plan. They can be addressed after launch based on what real users actually trip over.
-
- **Do not** raise or restructure the `MAX_CATEGORIES = 12` limit, even though it's tight for some real use cases.
- **Do not** refactor the `ExecuteCommand` vim command match ladder, even though it duplicates registry logic.
- **Do not** fix the hardcoded `"Measure"` category name in `evaluate_aggregated`, even though it's the one place in the code that assumes a specific user-facing name.
- **Do not** change `Model::evaluate` from a linear formula walk to a HashMap lookup, even though it's O(N·M·F) in the render hot path.
- **Do not** add render-pass memoization to `matching_values` calls.
- **Do not** fix the `ApplyAndClearDrill` HashMap iteration ordering issue around coordinate rename + value edit interactions.
- **Do not** add new features: no YoY references, no parameterized formulas, no Datalog backend, no undo/redo, no charts, no plugin system.
- **Do not** write a documentation site beyond the single GitHub Pages landing page in Phase 4.
- **Do not** add Windows support.
- **Do not** rename types, restructure modules, or do any "while I'm in here" cleanups.
-
-Each of these is worth doing eventually. None of them is worth doing before the launch post is up. The goal of this plan is to get the existing tool in front of strangers in a form they can install and try, not to make the tool perfect first.
-
---
-
-## Definition of done
-
-The plan is complete when, on a clean machine with only Nix installed:
-
-1. `git clone <repo> && cd improvise && nix develop` succeeds.
-2. `cargo build --release` succeeds.
-3. `./target/release/improvise examples/demo.improv` opens an interesting pivot immediately.
-4. The README renders correctly on GitHub with the inline GIF playing.
-5. `cargo install improvise` from a fresh shell works and produces a runnable binary.
-6. The GitHub releases page has prebuilt binaries for Linux x86_64 and macOS (Intel + Apple Silicon).
-7. The GitHub Pages site at `https://<user>.github.io/improvise/` loads and the asciinema casts play.
-8. Nothing in the "Out of scope" list has been touched.
-
-When all eight conditions hold, stop. Report back to the user with a summary of what was done and any blockers encountered. Do not post to Hacker News yourself — that's the user's call and their timing.

-## How to Find Things
-
-| I need to...                          | Look in                                      |
-|---------------------------------------|----------------------------------------------|
-| Add a new keybinding                  | `command/keymap.rs` → `default_keymaps()`    |
-| Add a new user-facing command         | `command/cmd/` → implement `Cmd` in the relevant submodule, register in `registry.rs` |

-## Core Types and Traits
-
-### Command/Effect Pipeline (the central architecture pattern)
-
-```
-User keypress → Keymap lookup → Cmd::execute(&CmdContext) → Vec<Box<dyn Effect>> → Effect::apply(&mut App)
-                (immutable)      (pure, read-only)            (state mutations)
-```
-
-```rust
-// src/command/cmd/core.rs
-pub trait Cmd: Debug + Send + Sync {
-    fn name(&self) -> &'static str;
-    fn execute(&self, ctx: &CmdContext) -> Vec<Box<dyn Effect>>;
-}
-
-pub struct CmdContext<'a> {
-    pub model: &'a Model,           // immutable
-    pub layout: &'a GridLayout,     // immutable
-    pub registry: &'a CmdRegistry,
-    pub mode: &'a AppMode,
-    pub selected: (usize, usize),   // (row, col) cursor
-    pub row_offset: usize,
-    pub col_offset: usize,
-    pub search_query: &'a str,
-    pub search_mode: bool,
-    pub yanked: &'a Option<CellValue>,
-    pub key_code: KeyCode,          // the key that triggered this command
-    pub buffers: &'a HashMap<String, String>,
-    pub expanded_cats: &'a HashSet<String>,
-    // panel cursors, tile cursor, visible dimensions...
-}
-
-// src/ui/effect.rs
-pub trait Effect: Debug {
-    fn apply(&self, app: &mut App);
-    fn changes_mode(&self) -> bool { false }  // override if effect changes AppMode
-}
-```
-
-**To add a command**: implement `Cmd` in the appropriate `command/cmd/` submodule, then register in `command/cmd/registry.rs`. Use the `effect_cmd!` macro (in `effect_cmds.rs`) for simple effect-wrapping commands. Bind it in `default_keymaps()`.
-
-**To add an effect**: implement `Effect` in `effect.rs`, add a constructor function.
-
-### Data Model
-
-```rust
-// src/model/types.rs
-pub struct Model {
-    pub name: String,
-    pub categories: IndexMap<String, Category>,  // ordered
-    pub data: DataStore,
-    pub formulas: Vec<Formula>,
-    pub views: IndexMap<String, View>,
-    pub active_view: String,
-    pub measure_agg: HashMap<String, AggFunc>,   // per-measure aggregation override
-}
-// Key methods:

-//   category(&self, name) -> Option<&Category>
-//   category_mut(&mut self, name) -> Option<&mut Category>
-//   set_cell(&mut self, key: CellKey, value: CellValue)
-//   evaluate(&self, key: &CellKey) -> Option<CellValue>          [formulas + raw data]
-//   evaluate_aggregated(&self, key, none_cats) -> Option<CellValue>  [sums over hidden dims]
-//   recompute_formulas(&mut self, none_cats)               [fixed-point formula cache]
-//   add_formula(&mut self, formula: Formula)       [replaces same target+category, adds item]
-//   remove_formula(&mut self, target, category)
-//   category_names(&self) -> Vec<&str>                    [includes virtual]
-//   regular_category_names(&self) -> Vec<&str>            [excludes _Index, _Dim, _Measure]
-
-const MAX_CATEGORIES: usize = 12;  // virtual categories don't count
-```
-
-```rust
-// src/model/cell.rs
-#[derive(Clone, PartialEq, Eq, Hash)]
-pub struct CellKey(pub Vec<(String, String)>);  // always sorted by category name
-// CellKey::new(coords) — sorts on construction, enforcing canonical form
-// CellKey::with(cat, item) -> Self — returns new key with coord added/replaced
-// CellKey::without(cat) -> Self — returns new key with coord removed
-// CellKey::get(cat) -> Option<&str>
-
-#[derive(Clone, PartialEq)]
-pub enum CellValue {

-
-```rust

-
-pub enum CategoryKind { Regular, VirtualIndex, VirtualDim, VirtualMeasure, Label }
-```
-
-### Formula System
-
-```rust
-// src/formula/ast.rs
-pub enum Expr {
-    Number(f64),
-    Ref(String),                           // reference to an item name
-    BinOp(BinOp, Box<Expr>, Box<Expr>),
-    UnaryMinus(Box<Expr>),
-    Agg(AggFunc, Box<Expr>, Option<Filter>),
-    If(Box<Expr>, Box<Expr>, Box<Expr>),
-}
-pub enum BinOp { Add, Sub, Mul, Div, Pow, Eq, Ne, Lt, Gt, Le, Ge }
-pub enum AggFunc { Sum, Avg, Min, Max, Count }
-pub struct Formula {
-    pub raw: String,              // "Profit = Revenue - Cost"
-    pub target: String,           // "Profit"
-    pub target_category: String,  // "Measure"
-    pub expr: Expr,
-    pub filter: Option<Filter>,   // WHERE clause
-}
-
-// src/formula/parser.rs
-pub fn parse_formula(raw: &str, target_category: &str) -> Result<Formula>
-```
-
-Formula evaluation is in `model/types.rs` → `eval_formula()` / `eval_expr()`. Operates at full f64 precision. Display rounding in `format.rs` is view-only.
-
-### View and Layout
-
-```rust
-// src/view/axis.rs
-pub enum Axis { Row, Column, Page, None }
-
-// src/view/types.rs
-pub struct View {
-    pub name: String,
-    pub category_axes: IndexMap<String, Axis>,
-    pub page_selections: HashMap<String, String>,
-    pub hidden_items: HashMap<String, HashSet<String>>,
-    pub collapsed_groups: HashMap<String, HashSet<String>>,
-    pub number_format: String,     // e.g. ",.0" or ",.2f"
-    pub prune_empty: bool,
-    // scroll/selection state...
-}
-// View::set_axis(&mut self, cat, axis)
-// View::axis_of(&self, cat) -> Axis
-// View::cycle_axis(&mut self, cat)        [Row→Column→Page→None→Row]
-// View::transpose(&mut self)              [swap Row↔Column]
-// View::categories_on(&self, axis) -> Vec<&str>
-// View::on_category_added(&mut self, cat) [auto-assigns axis]
-
-// src/view/layout.rs
-pub struct GridLayout { /* computed from Model + View */ }
-// GridLayout::new(model, view) -> Self
-// GridLayout::cell_key(row, col) -> Option<CellKey>
-// GridLayout::cell_value(row, col) -> Option<CellValue>
-// GridLayout::row_label(row) -> &str
-// GridLayout::col_label(col) -> &str
-// GridLayout::drill_records(row, col) -> Vec<(CellKey, CellValue)>
-// Records mode: auto-detected when _Index on Row + _Dim on Column
-```
-
-### App State
-
-```rust
-// src/ui/app.rs
-pub enum AppMode {
-    Normal,
-    Editing { minibuf: MinibufferConfig },
-    FormulaEdit { minibuf: MinibufferConfig },
-    FormulaPanel,
-    CategoryPanel,
-    ViewPanel,
-    TileSelect,
-    CategoryAdd { minibuf: MinibufferConfig },
-    ItemAdd { minibuf: MinibufferConfig },
-    ExportPrompt { minibuf: MinibufferConfig },
-    CommandMode { minibuf: MinibufferConfig },
-    ImportWizard,
-    Help,
-    Quit,
-}
-// Note: SearchMode is Normal + search_mode:bool flag, not a separate variant.
-
-pub struct App {
-    pub model: Model,
-    pub mode: AppMode,
-    pub file_path: Option<PathBuf>,
-    pub dirty: bool,
-    pub help_page: usize,
-    pub transient_keymap: Option<Arc<Keymap>>,  // for prefix keys
-    // layout cache, drill_state, wizard, buffers, panel cursors, etc.
-}
-// App::handle_key(&mut self, KeyEvent) -> Result<()>  [main input dispatch]
-// App::rebuild_layout(&mut self)
-// App::is_empty_model(&self) -> bool  [true when only virtual categories exist]
-```
-
-### Keymap System
-
-```rust
-// src/command/keymap.rs
-pub enum KeyPattern { Key(KeyCode, KeyModifiers), AnyChar, Any }
-pub enum Binding {
-    Cmd { name: &'static str, args: Vec<String> },
-    Prefix(Arc<Keymap>),                          // Emacs-style sub-keymap
-    Sequence(Vec<(&'static str, Vec<String>)>),   // multi-command chain
-}
-pub enum ModeKey {
-    Normal, Help, FormulaPanel, CategoryPanel, ViewPanel, TileSelect,
-    Editing, FormulaEdit, CategoryAdd, ItemAdd, ExportPrompt, CommandMode,
-    SearchMode, ImportWizard,
-}
-
-// Keymap::lookup(&self, key, mods) -> Option<&Binding>
-//   Fallback chain: exact(key,mods) → Char with NONE mods → AnyChar → Any
-
-// KeymapSet::default_keymaps() -> Self  [builds all 14 mode keymaps]
-// KeymapSet::dispatch(&self, ctx, key, mods) -> Option<Vec<Box<dyn Effect>>>
-```

-
-## File Format (.improv)
-
-Plain-text markdown-like, defined by a PEG grammar (`persistence/improv.pest`).
-Parsed by pest; the grammar is the single source of truth for both the parser
-and the grammar-walking test generator.
-
-**Not JSON** (JSON is legacy, auto-detected by `{` prefix).
-
-```
-v2025-04-09
-# Model Name
-Initial View: Default
-
-## View: Default
-Region: row
-Measure: column
-|Time Period|: page, Q1             ← pipe-quoted name, page with selection
-hidden: Region/Internal
-collapsed: |Time Period|/|2024|
-format: ,.2f
-
-## Formulas
- Profit = Revenue - Cost [Measure]     ← [TargetCategory]
-
-## Category: Region
- North, South, East, West              ← bare items, comma-separated
- Coastal_East[Coastal]                 ← grouped item (one per line)
- Coastal_West[Coastal]
-> Coastal                               ← group definition
-
-## Category: Measure
- Revenue, Cost, Profit
-
-## Data
-Region=East, Measure=Revenue = 1200
-Region=East, Measure=Cost = 800
-Region=West, Measure=Revenue = |pending|    ← pipe-quoted text value
-```
-
-### Name quoting
-
-Bare names match `[A-Za-z_][A-Za-z0-9_-]*`. Everything else uses CL-style
-pipe quoting: `|Income, Gross|`, `|2025|`, `|Name with spaces|`.
-Escapes inside pipes: `\|` (literal pipe), `\\` (backslash), `\n` (newline).
-
-### Section order
-
-`format_md` writes Views → Formulas → Categories → Data (smallest to largest).
-The parser accepts sections in any order.
-
-### Key design choices
-
- Version line (`v2025-04-09`) enables future format changes.
- `Initial View:` is a top-level header, not embedded in view sections.
- Text cell values are always pipe-quoted to distinguish from numbers.
- Bare items are comma-separated on one line; grouped items get one line each.
-
-Gzip variant: `.improv.gz` (same content, gzipped). Persistence code: `persistence/mod.rs`.
-

-## Testing Guidelines
-
-### Coverage target
-
-Aim for **~80% line and branch coverage** on logic code. This is a quality floor, not a
-ceiling — go higher where the code warrants it, but don't chase 100% on rendering
-widgets or write tests that just exercise trivial getters. Coverage should be run with
-`cargo llvm-cov` (available via `nix develop`).
-
-### What to test and how
-
-| Layer | Approach | Notes |
-|-------|----------|-------|
-| **Model** (types, cell, category, symbol) | Unit tests + **proptest** | The data model is the foundation. Property tests catch invariant violations that hand-picked cases miss (see CellKey sort invariant, axis consistency). |
-| **Formula** (parser, eval) | Unit tests per operator/construct | Cover each BinOp, AggFunc, IF, WHERE, unary minus, chained formulas, error cases (div-by-zero, missing ref). Ensure eval uses full f64 precision — never display-rounded values. |
-| **View** (types, layout) | Unit tests + **proptest** | Property tests for axis assignment invariants (each category on exactly one axis, transpose is involutive, etc.). Unit tests for layout computation, records mode detection, drill. |
-| **Command** (cmd, keymap, parse) | Unit tests | Test command execution by building a `CmdContext` and asserting on returned effects. Test keymap lookup fallback chain. Test script parser with edge cases (quoting, comments, dots). |
-| **Persistence** | Round-trip + grammar-generated | `save → load → save` must be identical. Grammar-walking generator produces random valid files from the pest AST; proptests verify `parse(generate())` and `parse(format(parse(generate())))`. Cover groups, formulas, views, hidden items, pipe quoting edge cases. |
-| **Format** | Unit tests | Boundary cases: comma placement at 3/4/7 digits, negative numbers, rounding half-away-from-zero (not banker's), zero, small fractions. |
-| **Import** (analyzer, csv, wizard) | Unit tests | Field classification heuristics, CSV quoting (RFC 4180), multi-file merge, date extraction. |
-| **UI rendering** (grid, panels, draw, help) | Generally skip | Ratatui widgets are hard to unit-test and change frequently. Test the *logic* they consume (layout, cat_tree, format) rather than the rendering itself. |
-| **Effects** | Test indirectly | Effects are thin `apply` methods. Test via integration: send a key through `App::handle_key` and assert on resulting app state. The complex ones (drill reconciliation, import) deserve targeted unit tests. |
-
-### Property tests (proptest)
-
-Use property tests for **invariants that must hold across all inputs**, not as a
-substitute for example-based tests. Good candidates:
-
- Structural invariants: CellKey always sorted, each category on exactly one axis,
-  toggle-collapse is involutive, hide/show roundtrips.
- Serialization roundtrips: save/load identity.
- Determinism: `evaluate` returns the same value for the same inputs.
-
-Keep proptest case counts reasonable. The defaults (256 cases) are fine for most
-properties. Don't crank them up to thousands — the test suite should complete in
-under 2 seconds. If a property needs more cases to feel confident, that's a sign
-the input space should be constrained with better strategies, not brute-forced.
-
-### Bug-fix workflow
-
-Per CLAUDE.md: **write a test that demonstrates the bug before fixing it.** Prefer
-a small unit test targeting the specific function over an integration test. The test
-should fail on the current code, then pass after the fix. Mark regression tests
-with a doc-comment explaining the bug (see `model/types.rs` `formula_tests` for
-examples).
-
-### What not to test
-
- Trivial struct constructors and enum definitions (`ast.rs`, `axis.rs`).
- Ratatui `Widget::render` implementations — these are pure drawing code.
- Module re-export files (`mod.rs`).
- One-line delegation methods.

-## Patterns to Know
-
-1. **Commands never mutate.** They receive `&CmdContext` (read-only) and return `Vec<Box<dyn Effect>>`.
-2. **CellKey is always sorted.** Use `CellKey::new()` — never construct the inner Vec directly.
-3. **`category_mut()` for adding items.** `Model` has no `add_item` method; get the category first: `m.category_mut("Region").unwrap().add_item("East")`.
-4. **Virtual categories** `_Index`, `_Dim`, and `_Measure` always exist. `is_empty_model()` checks whether any *non-virtual* categories exist. `_Measure` holds numeric data fields and formula targets; `add_formula` auto-adds the target item.
-5. **Display rounding is view-only.** `format_f64` (half-away-from-zero) is only called in rendering. Formula eval uses full f64.
-5b. **Formula evaluation is fixed-point.** `recompute_formulas(none_cats)` iterates formula evaluation until values stabilize, using a cache. `evaluate_aggregated` checks the cache for formula results. Circular refs produce `CellValue::Error("circular")`.
-6. **Keybindings are per-mode.** `ModeKey::from_app_mode()` resolves the current mode, then the corresponding `Keymap` is looked up. Normal + `search_mode=true` maps to `SearchMode`.
-7. **`effect_cmd!` macro** generates a command struct that just produces effects. Use for simple commands without complex logic.
-8. **`.improv` format is defined by a PEG grammar** (`persistence/improv.pest`). Parsed by pest. Names use CL-style `|...|` pipe quoting when they aren't valid bare identifiers. JSON is legacy only.
-9. **`IndexMap`** is used for categories and views to preserve insertion order.
-10. **`MAX_CATEGORIES = 12`** applies only to `CategoryKind::Regular`. Virtual/Label categories are exempt.

-# Design Notes
-
-> **Staleness warning:** This document captures conceptual framing from the
-> original specification. It is not kept in sync with the code. For current
-> architecture and types, see `context/repo-map.md` and
-> `context/design-principles.md`.
-
-## Product Vision
-
-Traditional spreadsheets conflate data, formulas, and presentation into a single
-flat grid addressed by opaque cell references (A1, B7). This makes models
-fragile, hard to audit, and impossible to rearrange without rewriting formulas.
-
-Improvise treats data as a multi-dimensional, semantically labeled structure --
-separating data, computation, and views into independent layers. Formulas
-reference meaningful names, views can be rearranged instantly, and the same
-dataset can be explored from multiple perspectives simultaneously.
-
-The application compiles to a single static binary and provides a rich TUI
-experience.
-
-## Non-Goals (v1)
-
- Scripting/macro language beyond the formula system.
- Collaborative/multi-user editing.
- Live external data sources (databases, APIs).
- Charts or graphical visualization.
- Multi-level undo history.
