This change resolves a critical UX bug where dynamic code generation was offered for Pocock-Simon minimization studies (causing dead-end generation/ZIP failures and CodeGenerationError displays).

Specifically, we have:

  1. Updated CodeGeneratorModalComponent to derive support from the active config. For MINIMIZATION studies, we defensively normalize exportMode to 'STATIC' in ngOnInit(), refreshCode(), and downloadCode().
  2. Disabled the DYNAMIC and BOTH segmented control options on the UI and added a clear, accessible explanatory tooltip note.
  3. Updated and expanded the unit/DOM test suite in code-generator-modal.component.spec.ts to ensure full coverage of stale-mode fallback, download normalization, and element disabling under minimization configurations.

Fixes #650

…Code Generator

- Modified CodeGeneratorModalComponent to default to and force STATIC exportMode when randomizationMethod is MINIMIZATION.
- Disabled DYNAMIC and BOTH export segmented buttons on the UI and replaced the explanatory note with a clear unsupported notice when minimization is selected.
- Updated and expanded the unit and DOM tests in code-generator-modal.component.spec.ts to fully verify stale-mode fallback, initialization normalization, download fallback, and disabled button elements with the unsupported tip.

Warning

Review limit reached

@fderuiter, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 68 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Summary by CodeRabbit

  • New Features
    • Pocock-Simon minimization now supports Static export mode only.
    • Dynamic Generator and Both export options are disabled when minimization is active.
    • The interface displays a notice explaining the restriction and confirming that static manifests preserve the generated allocation sequence.
  • Bug Fixes
    • Export settings now consistently revert to Static mode when unsupported options are selected.
  • Documentation
    • Updated the validation traceability matrix timestamp.

Walkthrough

The code generator modal now enforces Static export mode for Pocock-Simon minimization. Dynamic and Both options are disabled, and the notice explains the restriction. Tests now cover fallback behavior, downloads, and the updated DOM.

Changes

Pocock-Simon static export handling

Layer / File(s) Summary
Enforce Static export mode
src/app/domain/schema-management/components/code-generator-modal.component.ts
Initialization, mode changes, refresh, and downloads reset minimization exports to STATIC.
Update controls and regression coverage
src/app/domain/schema-management/components/code-generator-modal.component.html, src/app/domain/schema-management/components/code-generator-modal.component.spec.ts, Validation_Traceability_Matrix.md
The UI disables Dynamic and Both options and displays the minimization notice. Tests use Angular fixtures and verify fallback, download, banner, error, and DOM behavior. The traceability matrix timestamp was updated.

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

Mergeability Score: 🟡 Moderate · up to 1a12f

The change prevents unsupported dynamic generation for minimization studies, but downloads can still package stale dynamic output as a static file, leading to incorrect or failed generated artifacts. Merge should wait for regeneration after fallback and for the explanation to be associated with the disabled controls.

Associate the minimization explanation with the export controls.

The notice is a separate <p>. It does not provide an accessible description for the disabled Dynamic Generator and Both controls. This does not implement the required accessible explanatory tooltip or equivalent description.

Add a stable ID to the notice and reference it with aria-describedby on the export control group or on each disabled control.

Regenerate the preview after download-mode normalization.

If currentCode contains a Dynamic preview, Lines 197-199 only change the mode signal. Line 234 then writes the stale Dynamic code into a file named as a Static manifest.

Refresh the code after this fallback and stop if generation sets errorState. Extend the download test to inspect the primary ZIP entry after it starts from DYNAMIC.

Proposed fix
-    if (this.isMinimization()) {
+    if (this.isMinimization() && this.exportMode() !== 'STATIC') {
       this.exportMode.set('STATIC');
+      await this.refreshCode();
+      if (this.errorState()) return;
     }

…Code Generator

- Modified CodeGeneratorModalComponent to default to and force STATIC exportMode when randomizationMethod is MINIMIZATION.
- Disabled DYNAMIC and BOTH export segmented buttons on the UI and replaced the explanatory note with a clear unsupported notice when minimization is selected.
- Updated and expanded the unit and DOM tests in code-generator-modal.component.spec.ts to fully verify stale-mode fallback, initialization normalization, download fallback, and disabled button elements with the unsupported tip.
- Fully restored DOM spy mocks on document.body in spec files to prevent NG05104 selector mismatch errors on sequential TestBed runs.
