DISCLOSURE: LLM-GENERATED TEXT

Why: Both asset workspaces showed Unity's generic "List is empty" text, which read as a finished search with no matches and never said how to start one.

What:

  • Name the saved-search state in the results area
  • Report a clean validation instead of a blank list
  • Share the list box shape so paging stays in place

Refs #312

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update
  • Refactor (code change that neither fixes a bug nor adds a feature)

Checklist

  • I have added tests that prove my fix is effective or my feature works
  • I have updated the documentation accordingly
  • I have updated the CHANGELOG for user-facing changes
  • My changes do not introduce breaking changes, or breaking changes are documented

Empty Saved searches workspace with guidance

Clean validation report

The Saved searches panel showed Unity's generic "List is empty" text before
any search was applied, so it read as a finished search with no matches and
never named how to start one. Asset validation used the same text after a
clean run, leaving only the findings count to show the result.

Both panels now keep a state-specific message in the result area and hide the
list while no rows exist. The message shares the list box shape so the paging
row stays in place. No query or validation behavior changed.

Walkthrough

Saved searches and asset validation now show explanatory empty states. The messages distinguish unapplied or ongoing operations from completed operations with no results. Results lists are hidden when empty and shown when results exist.

Changes: Asset workspace empty states

Layer / File(s) Summary
Saved search empty states
Editor/DataVisualizer/SavedAssetSearchPanel.cs, Editor/DataVisualizer/Styles/StyleConstants.cs, Editor/DataVisualizer/Styles/DataVisualizerStyles.uss, Tests/Editor/SavedAssetSearchTests.cs, Tests/Artifacts/asset-workspace-empty-searches-2026-11-03.png.meta, docs/search-and-filter.md, CHANGELOG.md
The panel distinguishes an unapplied search, a search with matches still arriving, and a completed search with no matches. It hides the results list when empty. Tests and documentation describe these states.
Validation empty states
Editor/DataVisualizer/AssetValidationPanel.cs, Tests/Editor/EditorAssetValidationTests.cs, Tests/Artifacts/asset-workspace-empty-validation-2026-11-03.png.meta, docs/managing-assets.md
The panel distinguishes no validation run, a run in progress, and a completed run with no findings. It shows the results list when findings exist. Tests and documentation describe these states.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Possibly related issues

  • Issue 305: The change updates asset-workspace guidance and related documentation, which matches part of the broader workflow and documentation scope.
  • Issue 312: The change clarifies Saved searches and Asset validation empty states, which relates to asset-workspace usability.
Merge Risk: Moderate · up to 3cf17

The saved-search test can time out on larger projects even for valid searches; resolve the completion-wait reliability risk before merging.

CodeRabbit found that a cancelled saved-search query stayed incomplete, so
the empty-state message kept saying the search was still running. The
validation panel had the same gap for a cancelled run.

Both panels now check cancellation before incompleteness and name the stopped
partial work. New cancellation tests click the panels' own cancel commands.

Trivial · Functional Correctness · Quick win

Test the populated saved-search transition.

The panel has a separate branch for populated results, but the current tests cover only empty, zero-match, and cancelled states. Use the existing EditorOnlyCreationData fixture to apply a search that returns Needle.asset, then assert the transition from the hidden empty state to a visible list containing one result.

CodeRabbit asked for the branch where a saved search returns rows, which the
empty-state tests did not exercise. The new case applies a matching saved
search and requires the empty message to give way to a listed result.

CodeRabbit review: the completion waits relied on the panel's 100 ms
scheduler, so a slow index scan could outlast the 10 second deadline.
Advance the query each iteration. Also save only the fixture asset
instead of every dirty asset in the project.

Validated: 13 SavedAssetSearchTests and 9 EditorAssetValidationTests
pass on the 6000.6 host; npm run check:gate passes.
Resolve the CHANGELOG ordering conflict after #532 and keep both

assets. CreateAsset now saves its own fixture, and the tests that dirty
an existing fixture save only that asset.
