Bug fixes: - Fix garbled error messages in chat (TypeWriter rendering issue) - Fix R engine NA crash in descriptive.R (defensive isTRUE/is.na checks) - Fix intent misclassification for statistical significance queries - Fix step 2 results not displayed (accept warning status alongside success) - Fix incomplete R code download (only step 1 included) - Fix multi-task state confusion (clicking old card shows new results) - Add R engine and backend parameter logging for debugging Refactor - Unified Record Architecture: - Replace 12 global singleton fields with AnalysisRecord as single source of truth - Remove isWorkflowMode branching across all components - One Analysis = One Record = N Steps paradigm - selectRecord only sets currentRecordId, all rendering derives from currentRecord - Fix cross-hook-instance issue: executeWorkflow fallback to store currentRecordId Updated files: ssaStore, useWorkflow, useAnalysis, SSAChatPane, SSAWorkspacePane, SSACodeModal, WorkflowTimeline, QueryService, WorkflowExecutorService, descriptive.R Tested: Manual integration test passed - multi-task switching, R code completeness Co-authored-by: Cursor <cursoragent@cursor.com>
