Narrows Digital Workshop to three pillars: library management, CAM, and sender + machine control. Projects stay, reshaped to work like a slicer project: design → CAM setup → G-code → run. The screen now uses the Bambu Studio / OrcaSlicer layout (stages 7–9), and PR builds now publish a Linux installer (stage 10). The direction is written up in .planning/WORKSHOP-SCOPE.md.

Each stage is its own commit.

1. Remove the GraphQLite graph layer and the dead DW_BUILD_TOOLS option

• GraphManager was written on every import and category change, but nothing ever read from it. Removed the module, the GraphQLite download, its release-payload requirement, and the now-unused SQLite extension-loading API.
• The Linux installer removes a graphqlite.so left behind by older installs.
• DW_BUILD_TOOLS pointed at tools/matgen and tools/texgen, which don't exist.

2. Remove project costing, the Cut Optimizer, and stock sizes

• Removed the costing engine and panel, rate categories, board-foot math, the cut optimizer (core, panel, .clo files), and per-material stock sizes, plus their menus, saved-layout keys, and tests.
• No costing, cut-plan, or stock data is deleted. Existing databases keep their costing_records / cut_plans / rate_categories / stock_sizes tables. New databases and upgrades don't create them. (Stage 5 removes only the project index rows that pointed at them.)
• .dwproj export no longer writes costs.json / cut_plans.json. Older archives that contain them still import (new test).
• The Materials panel keeps the material list (feeds & speeds reads it). Only its stock-size table goes.

3. Replace the Project Plan with a slicer-style contents tree

• Removed the six-stage Project Plan module, its view, its adapters, and the run-truth reporting that only fed it.
• The Project panel now shows each design, the CAM setups made from it, the G-code they produced, and the runs of that G-code. Designs and setups have Open in CAM, and there's an Add Design from Library button. Stale G-code reads Out of date, interrupted runs read Interrupted, and the state is always shown as text, not color alone.
• Removed the guided carve step flow (PrepareCarveFlow and step guidance), which nothing in the app used. preparation_identity stays, because the protected Run package is keyed on it.
• New setups are named "CAM Setup: ". The stored source key keeps its old spelling, so setups saved by earlier releases still resolve.

4. Remove the Guided Workshop experience

• Removed View → Experience, the experience router, and the ExperienceMode field on every workshop intent.
• Layouts: migration v2 folds the old Guided Workshop and Advanced Workbench built-ins into one Workshop layout. Custom layouts are preserved byte-for-byte, and the active selection maps across (new test covers each case).
• A G-code stream now always holds the Sender workspace, which is what happened in practice without Guided.
• The responsive layout helpers lose their "Guided" names (workshop_layout_metrics.h).

5. Trim project item types

• Drop the Stock, CutPlan, Cost, Labor, Consumable, and Zeroing item types. A project now holds designs, CAM setups, G-code, runs, and the materials and tools they need.
• Schema v19 removes index rows of those types once (new migration test), and project sync prunes any that reappear. The source tables are still left alone.
• New project folders no longer get heightmaps/ (left over from the removed Direct Carve CAM) or costing/. Existing folders are untouched.

6. Docs

• New .planning/WORKSHOP-SCOPE.md: the three-pillar scope, the slicer project model, and PureCutCNC used for toolpath math only through the existing stateless POST /api/job JobSpec endpoint (no web-UI parity requirement), plus revised CAM phases 3–7.
• CAM-INTEGRATION-DESIGN.md is marked partly superseded. STATE, PROJECT, MILESTONES, ROADMAP, and the README are updated.

7. Slicer-style main tab rules

• Home, Library, Prepare, Preview, Device, Project, plus the rules for entering them and for the two primary actions: a running job holds Device; Generate stays blocked until the CAM rebuild can make toolpaths; Send to Machine needs loaded G-code and an idle machine. Each block has a plain-language reason. UI-free and unit tested (main_tabs.*).

8. Lay out the app like a 3D-printing slicer

• Top bar: menu button (File, Edit, View, Tools, Help) and Save; the six tabs; project name and save state; machine status with Connect/Disconnect; Generate and Send to Machine where a slicer puts Slice and Print.
• Prepare: sidebar with Tool & Material, project contents, and CAM | Properties, beside the 3D canvas. Preview: G-code statistics and listing beside the toolpath and playback. Device: live view with G-code, job progress, and MDI underneath, and status, jog, and safety (plus WCS, Tool & Material, Macros, Machine Settings) on the right. Library, Home, and Project get their own pages.
• Opening a design lands in Prepare, G-code in Preview (previously project G-code opened the Sender). Send to Machine opens loaded G-code in Device and never starts the machine.
• Pages are ImGui dock layouts rebuilt on tab change and locked against undocking. Section widths come from the font size. Page windows have no close buttons. Materials, Tool Library, Machine Profiles, Lighting, and Log Viewer stay floating.
• Ctrl+1–6 switch tabs (Ctrl+1/2 used to be Workshop/Sender).
• Leaving the Library runs its existing return path first. Prepare, Preview, and Project re-enter the project the way Back to Project did.
• Removed: layout presets in the UI, group panels, auto-context switching, the Workshop/Sender toggle, and the project context bar. Saved presets stay in the config file but are no longer read.

9. Compact project contents

• One line per design, setup, G-code file, or run: icon and name on the left, state in words on the right. Click or Enter opens. The selected design offers Open in CAM, and a right-click menu has the same actions.

10. Linux installer on pull request builds

• CI passed the PR ref (12/merge) to make-installer.sh as the version, so the .run path pointed into a missing directory and no Linux artifact was uploaded (only a warning). Slashes are now replaced, and PR builds publish DigitalWorkshop-linux like Windows and macOS. I downloaded that artifact, installed it into a clean home, and launched it.

Not done here (open decisions, listed in the scope doc)

• AI tagging: kept for now as a library feature.
• Materials: two material systems (the .dwmat Materials panel and the .vtdb tool database's own material table) should be merged.
• Home could become a slicer-style start screen with project thumbnails, and the Library's picker modes could fold into a plain "Add to Project".
• Saved layout presets are still stored and migrated in the config, but nothing reads them. They can be removed in a follow-up.
• web/season-countdown/ is an unrelated app living in this repo. I left it alone.

Verification (local, Linux GCC Release)

• Baseline on main: 1,496 passed / 2 skipped (both need optional external fixtures).
• Head of this branch: 1,261 passed / 2 skipped. Every test that went away belonged to a removed feature. New tests cover the project contents tree, the v2 layout migration, the v19 schema migration, retired-item pruning, legacy .dwproj import, the main tab rules, and the side-column layout sizing.
• All six isolated module suites pass.
• check_source_sizes passes. Caps were lowered or removed where files shrank or were deleted.
• No new compiler warnings in touched files.
• I verified the build and tests after each stage, not each individual commit (stage 8 was also checked alone). CI covers Windows, macOS, clang, and the Debug -Werror coverage build.
• Ran the app under Xvfb and clicked through every tab: opened a recent project, opened a design (Prepare), opened its G-code (Preview), used Send to Machine (Device), visited Library and Project, opened the menu, and switched tabs with Ctrl+3 and Ctrl+5.
