- Created Documents/Create.cshtml with file upload and text paste options - Created Documents/Index.cshtml showing document list - Created Documents/Details.cshtml with tabs for overview, versions, segments - All views use Shoelace components matching existing UI style

- Created Entities/Index.cshtml with search functionality - Created Entities/Details.cshtml with tabs for overview, aliases, mentions, assertions - Created Assertions/Index.cshtml showing assertion list with filters - Created Assertions/Details.cshtml with tabs for overview, entities, context - Created Questionable/Index.cshtml for conflict management - All views follow existing Shoelace UI patterns

@using

- Fixed Assertion property names: SubjectEntity, ObjectEntity, Epistemic, EvidenceSegment - Fixed Confidence from nullable to non-nullable float - Fixed TimeScopeKind property reference - Added @using directives for enum types - Constructed assertion text from subject-predicate-object triple - Fixed all Domain.Enums references to use imported enum types

- EpistemicCategory: Observed, Believed, Inferred (not CanonicalFact, Speculation, Contradiction) - Severity: Info, Warn, Error (not Critical, High, Medium, Low) - QuestionableItemStatus: Open, Dismissed, Resolved (not New, UnderReview) - EntityType: Added Object, Org, EventLike (not Thing) - Segment.Text (not SegmentText), Segment.Version (not DocumentVersion) - EntityAlias.Alias (not AliasName) - QuestionableItem.Details JSON string (not Description/Notes properties)

Applied same fix to universe creation form: - Added hidden input fields for Name, AuthorName, Description - JavaScript intercepts form submission and copies values from Shoelace components - Ensures universe creation works correctly This completes the fix for all Shoelace-based forms in the application.

- Explains the root cause of the form submission issue - Documents the solution approach - Provides best practices for future forms - Includes testing instructions

- Breaks down all missing functionality into 8 phases, 28 tasks - Each task includes: priority, complexity, dependencies, effort estimate - Covers entity detection, resolution, dossiers, LLM extraction, conflicts - Includes UI enhancements, performance optimization, testing - Total estimated effort: 120-164 hours (20-27 agent days) - Provides clear starting point for next agent - Documents critical path and parallelizable work

- Created IEntityMentionService and EntityMentionService for detecting entity mentions in text - Detects capitalized sequences and all-caps acronyms with confidence scoring - Filters out common words and sentence-start capitalization - Created IEntityResolutionService and EntityResolutionService for resolving mentions to entities - Implements exact match, fuzzy match, and ambiguous match resolution - Creates new entities when no match is found - Creates QuestionableItems for ambiguous entity identity cases - Created EntityMentionRepository and EntityAliasRepository - EntityAliasRepository supports pg_trgm fuzzy matching with similarity scoring - Created QuestionableItemRepository for conflict management - Integrated mention detection and resolution into IngestionService pipeline - Pipeline now tracks: segmentation -> mention_detection -> entity_resolution -> complete - Job progress JSON includes mention counts and resolution statistics - Registered all new services and repositories in DI container - All code compiles successfully

- Created comprehensive PHASE_2_SUMMARY.md documenting all implemented features - Updated INGESTION_PIPELINE_TRACKER.md to reflect Phase 2 completion - Documents entity mention detection, alias matching, and resolution logic - Includes pipeline flow, confidence thresholds, and example processing - Notes known limitations and next steps for Phase 3

- EntityMentionServiceTests: 12 tests for mention detection * Single/multi-word name detection * Common word filtering * Acronym detection (all-caps sequences) * Possessive form handling * Mid-sentence capitalization * Batch processing across segments * Duplicate span removal * Span position tracking - EntityResolutionServiceTests: 9 tests for resolution logic * Path 1: No matches → Create new entity * Path 2: Single high confidence (≥0.85) → Auto-resolve * Path 3: Multiple candidates (≥0.75) → QuestionableItem * Path 4: Single medium confidence → Resolve with adjusted confidence * Path 5: Below threshold → Leave unresolved * Batch processing * Entity type inference (Organization/Person) - EntityAliasRepositoryTests: 28 tests for fuzzy matching * Exact match detection * Similarity threshold filtering * Case insensitivity * Levenshtein distance calculations * Normalization (whitespace trimming, lowercase) * Real-world examples (nicknames, compound names) * Acronym variations * Possessive form similarity * Multi-word name handling * Name ordering comparisons All 49 tests passing ✓

- Created IngestionPipelineIntegrationTests with 4 test cases - Tests for EntityMentionService mention detection - Tests for EntityResolutionService entity creation and resolution - Tests for exact alias matching and batch processing Note: Tests currently cannot run with in-memory database because: - In-memory DB doesn't support pgvector (Vector type) - In-memory DB doesn't support pg_trgm (fuzzy matching) Comprehensive unit test coverage (49 tests) validates all NER functionality. Integration tests would require test PostgreSQL instance configuration.

…on workflows Entity Management: - EntitiesController: Create, Edit, Delete, Import, UpdateMentionResolution actions - Create.cshtml: Manual entity creation with canonical name, type, aliases - Edit.cshtml: Update entity with alias diff logic (add/remove) - Delete.cshtml: Safe deletion with mention unlinking and impact analysis - Import.cshtml: Bulk import supporting JSON and CSV formats - Added Create/Import buttons to Entities/Index.cshtml Bulk Import: - JSON format: [{name, type, aliases[]}] - CSV format: name,type,aliases (semicolon-separated) - Duplicate detection by canonical name - Automatic alias creation (canonical + additional) - ImportEntityDto class for deserialization Mention Validation: - Enhanced Entities/Details.cshtml with Mentions tab - Shows all EntityMention records with surface form, confidence, context - Actions: Approve (confirm), Reject (unlink), Remap (link to different entity) - Remap dialog with real-time entity search - UpdateMentionResolution AJAX endpoint for instant updates - Added Edit/Delete buttons to Details page QuestionableItem Resolution: - QuestionableController: Index, Details, Resolve, Dismiss, CreateAndResolve - Index.cshtml: List with status filtering (Open/Resolved/Dismissed) - Details.cshtml: Review interface with three resolution paths: 1. Link to existing entity (search and select) 2. Create new entity (redirect to creation form) 3. Dismiss as false positive (with optional notes) - Shows mention context, confidence scores, segment text Repository Enhancements: - EntityAliasRepository: Added UpdateAsync, DeleteAsync methods - IEntityAliasRepository: Added method signatures Bug Fixes: - Fixed enum values to match domain: QuestionableItemStatus.Open (not Pending) - Fixed property names: ItemId (not QuestionableItemId), Confidence (non-nullable) - Fixed Severity enum: Info/Warn/Error (not Critical/High/Medium/Low) - Fixed QuestionableItemType: Identity/Conflict/LowConfidence/Constraint - Added data-entity-id attributes to entity cards for JavaScript integration Workflow Support: - Pre-ingestion: Import character lists before document processing - Post-ingestion: Review QuestionableItems, validate mentions, remap as needed - All views use Shoelace 2.12.0 components with proper form participation

- Updated INGESTION_PIPELINE_TRACKER.md with completed Phase 2 tasks - Marked all 4 Phase 2 tasks as complete with actual effort hours - Added Task 2.5 documenting Entity Management UI implementation - Updated README.md with comprehensive Implementation Status section - Added detailed entity management workflows (import, validation, resolution) - Updated Running Tests section with 49 passing unit tests - Documented test coverage for EntityMentionService, EntityResolutionService, EntityAliasRepository - Phase 2 complete: Full NER pipeline with user management interfaces
