feat(studio): add feature previews and focus model details - #356
Keep experimental 3D views optional while letting people understand and retain independent preview choices per browser.
Keep preview illustrations faithful to the available model views so people know what they are enabling.
Give model details more room and prioritize documentation, scenarios, and information relevant to the selected entity.
Keep backend review consoles out of generic entity details and avoid empty validation tabs.
Make connection status recognizable without competing with model controls for header space.
Require a patched MCP transport release so security checks protect normal builds and fuzz tooling.
Note
Medium Risk
Studio removes in-UI responsibility and source-control inspection (behavioral/product shift), and bumps MCP (rmcp) and related Rust deps across server and fuzz builds.
Overview
Studio is rebranded to Atlas in the header and e2e expectations, with clearer live-connection copy and no schema-version badge in the model bar.
Feature Preview adds a More actions flow to opt into Lane mesh and Stream towers independently; choices persist per browser via localStorage and gated ?view= tabs fall back to the board when disabled. Previews render sample 3D scenes (with tests) and stay off for HTML snapshots.
Entity Details are refocused: wider side panels, Doc first on Details, slice Scenarios on their own tab, and Validation only when there are findings or a validation error. Responsibility and source integration backend review UIs are removed from Details (and related tests/docs now point inspection to CLI/MCP). Decision/document inspectors stay scoped to those entity kinds.
Canvas toolbar layout changes keep validation controls from overlapping view tabs and preserve panning between toolbar buttons; new Playwright coverage exercises those cases.
Rust workspaces pin rmcp 3.9.0 (with lockfile churn including MCP transport deps); Studio adds zod for flag parsing.
Reviewed by Cursor Bugbot for commit 202793c. Bugbot is set up for automated code reviews on this repo. Configure here.
Studio adds browser-persisted controls for Lane mesh and Stream towers previews. ModelShell gates each view by its flag and model content. The Inspector adds a Scenarios tab, conditionally displays Validation, and removes responsibility and source-integration review panels. The board toolbar and Inspector layouts also change.

Studio Feature Previews

Summary
Feature flags and view availability tsworkspace/webapps/studio/src/lib/feature-flags.ts, tsworkspace/webapps/studio/src/lib/feature-flags.test.ts, tsworkspace/webapps/studio/src/components/ModelShell.tsx, tsworkspace/webapps/studio/src/components/ModelShell.test.tsx
The feature-flag store persists independent settings and synchronizes changes across consumers. ModelShell gates Lane mesh and Stream towers by their flags, snapshot status, and model content. Tests cover persistence, storage failures, and view behavior.
Preview model and illustration tsworkspace/webapps/studio/src/lib/feature-preview-model.ts, tsworkspace/webapps/studio/src/components/FeaturePreviewIllustration.tsx, tsworkspace/webapps/studio/src/components/FeaturePreviewIllustration.test.tsx
A generated checkout model supplies entities for the previews. The illustration renders the selected view and tracks selections. Tests check scene content, disposal, and unavailable WebGL.
Preview dialog and menu integration tsworkspace/webapps/studio/src/components/FeaturePreviewDialog.tsx, tsworkspace/webapps/studio/src/components/TopBarMenu.tsx, tsworkspace/webapps/studio/src/components/TopBar.tsx, tsworkspace/webapps/studio/src/components/ui/dropdown-menu.tsx, tsworkspace/webapps/studio/src/components/TopBarMenu.test.tsx, tsworkspace/webapps/studio/src/components/TopBar.test.tsx, tsworkspace/webapps/studio/README.md, tsworkspace/webapps/studio/package.json, tsworkspace/webapps/studio/e2e/*
The More actions menu opens a dialog with independent switches, preview descriptions, and focus handling. TopBar passes feature state to the menu and changes its heading and connection indicator. The README documents preview controls and availability. E2E assertions now expect the Atlas heading.
The Inspector moves slice scenarios to a dedicated tab and shows Validation only when findings or an error exist. It removes the responsibility and source-integration review components. Tests cover tab behavior, scenario rendering, and the absence of responsibility queries.
Inspector panels use wider drawers with viewport-based maximum widths. Documentation directs responsibility and source-control inspection to CLI or MCP and states that these controls are absent from entity Details.
The board toolbar and right-side controls wrap and constrain overflow. End-to-end tests check validation-drawer visibility, tab selection, canvas hit-testing, and dragging at narrow widths.

Merge Risk: Low · up to 20279
The layout test does not need the proposed polling change. The icon-only connection indicator remains harder to interpret without hover or color distinction, but this is a bounded usability risk rather than a merge blocker.

- Around line 524-527: Update the active-tab handling around requestedTab so a
Scenarios or Validation tab that was active and later becomes unavailable is
cleared to Details, preventing it from reopening when data returns. Preserve an
initially unavailable controlled request so it can activate once available, and
add rerender tests covering both controlled and uncontrolled usage.

The header assertion request in this review and this summary is fixed in 310ba7f; the Chromium suite passes (14 passed, one existing skip).
Declining the blanket docstring-coverage request because repository conventions call for comments that explain non-obvious intent, and summaries on every touched UI function would restate the code.
Regarding this review: the stale-tab behavior is fixed in 4be34a4 with controlled and uncontrolled rerender coverage for Scenarios and Validation. The icon-only connection indicator follows the requested design. The blanket docstring-coverage request remains declined under the repository's convention of documenting non-obvious intent rather than repeating UI function behavior.

The toolbar overlap reported in this review is fixed in ab10837. The full Chromium suite passes with 15 tests passed and one existing realtime skip; the new regression checks header hit-testing and view switching at 480px and 640px. The blanket docstring-coverage request remains declined under the repository's comment conventions.
The pointer-capture and wrapping issue in this review is fixed in 202793c. Both browser cases failed before the fix and now pass; the full Chromium suite has 16 tests passed and one existing realtime skip. Typechecking, lint, and formatting also pass.
