This was unreliable because some test modules are not compatible with newer Drupal CMS majors (for example CMS 2.x). This caused avoidable install and test failures.</p> <p>Additionally, QA testing often requires testing incompatible module combinations (e.g., AI 2.0.x with ai_context 1.0.x which requires AI ^1.3), but lenient mode had to be manually enabled and had a critical bug preventing it from working.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <ol> <li>Implement intelligent version resolution that auto-detects the highest compatible Drupal CMS/Core version based on module requirements</li> <li>Make lenient mode the default (<code>DP_FORCE_DEPENDENCIES=1</code>) to allow incompatible version combinations for QA testing</li> <li>Fix the lenient plugin activation bug that prevented it from working</li> <li>Implement CMS core-extraction to bypass drupal_cms_ai constraints</li> <li>Update browser extension to reflect new defaults and improve UX</li> </ol> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <ul> <li>[x] Implement compatibility-based CMS version resolver</li> <li>[x] Wire resolver into workflow path when <code>DP_VERSION</code> is empty</li> <li>[x] Fix/enhance lenient plugin</li> <li>[x] Implement CMS core-extraction logic to bypass drupal_cms_ai constraints</li> <li>[x] Make lenient mode the default (<code>DP_FORCE_DEPENDENCIES=1</code>)</li> <li>[x] Add automated tests for: <ul> <li>ai_context with auto-detect AI version (resolves to AI 1.x)</li> <li>Force AI 2.0.x without lenient mode (expected failure)</li> <li>Force AI 2.0.x with lenient mode (succeeds)</li> </ul> </li> <li>[x] Update browser extension: <ul> <li>Remove DP_FORCE_DEPENDENCIES checkbox</li> <li>Update placeholders to "Auto-detect compatible version"</li> <li>Update help text to explain auto-detection</li> <li>Improve link colours for accessibility (just a nice-to-have whilst we are getting another review)</li> </ul> </li> <li>[x] Update workflow documentation: <ul> <li>README.md with lenient mode section</li> <li>Troubleshooting guide with lenient mode debugging</li> <li>AI lenient plugin README with comprehensive documentation</li> </ul> </li> </ul> <h3 id="summary-api-changes">API changes</h3> <p><strong>Environment Variables:</strong></p> <ul> <li><code>DP_FORCE_DEPENDENCIES</code> - Default changed from <code>0</code> to <code>1</code></li> <li><code>DP_VERSION</code> - Empty now triggers auto-detection (not "latest")</li> </ul> <p>No external API changes - Internal workflow behaviour only.</p> <h3 id="summary-data-model-changes">Data model changes</h3> <p>None.</p>
