Subject: [PATCH 02/11] feat(ui/labels): add instance count preview to Pull
 from Neo4j button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds confirmation modal showing instance count before pulling schema:
- Uses existing /api/labels/<name>/instance-count endpoint
- Shows modal with preview of what will happen
- Displays Neo4j instance count (or error if not connected)
- User can confirm or cancel action
- Improves safety by showing impact before schema pull

Frontend changes:
- Add confirmation modal HTML component
- Add showConfirmModal() helper function
- Add getInstanceCount() async function
- Update pullFromNeo4j() to show modal with instance count
- Loading state while fetching count
- Error handling for Neo4j not connected

Testing:
- 3 unit tests for instance count endpoint
- Tests endpoint exists and handles errors gracefully
- All tests passing

Acceptance criteria met:
✅ Pull button shows instance count in modal
✅ User can confirm/cancel before action
✅ Clear feedback on what will happen
✅ Handles Neo4j not connected gracefully

Subject: [PATCH 03/11] feat(ui/labels): add CSV export/import and push
 confirmation for instances
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends instance editing with spreadsheet workflow:

CSV Export/Import:
- Download CSV button (appears after pulling instances)
- Upload CSV button (always visible)
- CSV format: neo4j_id, property1, property2, ...
- Proper CSV escaping (quotes, commas, newlines)
- Change detection (highlights modified cells)
- Merge uploaded data with existing instances

Push Confirmation Modal:
- Shows preview before pushing changes
- Displays count of updates vs creates
- User can confirm or cancel
- Reuses existing confirmation modal component

Workflow:
1. Pull instances from Neo4j → Table displays
2. Edit inline OR Download CSV → Edit in Excel → Upload CSV
3. Changed cells highlight in yellow
4. Click 'Push Changes' → Confirmation modal shows preview
5. Confirm → Pushes to Neo4j

Features:
✅ Download instances as CSV with neo4j_id
✅ Upload CSV to populate/update instances
✅ Inline editing still works (existing feature)
✅ Push preview shows change count
✅ Handles CSV edge cases (quotes, commas, newlines)
✅ Change tracking and highlighting

This enables the 'spreadsheet editor for knowledge graph' use case!

From c0913e88cf7da74f5c685b58028fe489ce451a12 Mon Sep 17 00:00:00 2001

Subject: [PATCH 04/11] feat: Complete data cleaning workflow with property
 removal and overwrite mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit implements a complete data cleaning workflow for Neo4j knowledge
graphs through the spreadsheet interface, enabling users to:
1. Remove properties from label schema
2. Automatically update instance table (columns disappear)
3. Push with Overwrite mode to clean Neo4j nodes

**Frontend Changes (labels.html):**
- Added handlePropertyRemoval() function to clean instanceChanges when properties deleted
- Modified createPropertyRow() to track property names via data-prop-name attribute
- Updated saveLabel() to refresh instance table after schema changes
- Added Push Mode selection modal with Merge/Overwrite radio buttons
- Modified pushInstances() to support both merge and overwrite modes
- Overwrite mode builds complete property sets from schema and sends PUT requests

**Backend Changes:**
- Added PUT endpoint /api/labels/<name>/instances/<instance_id> in api_labels.py
- Implemented overwrite_label_instance() in label_service.py
- Uses Cypher SET n = {properties} to replace all properties (removes extras)

**Data Cleaning Workflow:**
1. User pulls instances from Neo4j
2. User removes unwanted properties from label schema in editor
3. User saves label → table updates (columns for removed properties disappear)
4. User selects Overwrite mode in push confirmation modal
5. Push removes properties not in schema from Neo4j nodes

This enables complete dataset cleaning by removing unwanted properties
from the knowledge graph while maintaining data integrity for schema-defined
properties.

Subject: [PATCH 06/11] fix(ui/labels): only gather outgoing relationships in
 saveLabel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed issue where saveLabel tried to gather data from incoming relationship
rows which are display-only and don't have data-field inputs. This caused
errors and prevented the editor from switching back to read-only mode after save.

Now only queries relationships-container (outgoing, editable) and ignores
incoming-relationships-container (display-only).

Subject: [PATCH 07/11] feat(ui/labels): add delete functionality for incoming
 relationships
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allows users to delete incoming relationships (relationships from other labels
pointing to this label) directly from the edit view.

**Features:**
- Added delete (×) button to each incoming relationship row in edit view
- Confirmation modal shows relationship details before deletion
- Automatically updates source label by removing the relationship
- Refreshes current label to show updated incoming relationships
- Returns to read-only mode after successful deletion

**Implementation:**
- deleteIncomingRelationship() fetches source label, removes relationship, saves
- Uses existing API endpoints (GET /api/labels/{name}, POST /api/labels)
- Incoming relationships automatically recompute after source label update
- No backend changes needed (uses existing label save logic)

This completes the data cleaning workflow by allowing users to clean up
both unwanted properties and unwanted relationships in their knowledge graph.

Subject: [PATCH 08/11] feat(ui/labels): add ability to create incoming
 relationships from target label
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allows users to add incoming relationships (from other labels to this one)
directly from the target label's edit view, completing bidirectional
relationship management.

**Features:**
- Added 'Add Incoming Relationship' button in edit view
- Modal with source label dropdown and relationship type input
- Validates that relationship doesn't already exist
- Updates source label definition automatically
- Refreshes current label to show new incoming relationship
- Returns to read-only mode after successful addition

**Workflow:**
1. User views target label (e.g., 'Sample')
2. Clicks 'Add Incoming Relationship'
3. Selects source label (e.g., 'Experiment') from dropdown
4. Enters relationship type (e.g., 'HAS_SAMPLE')
5. Confirms → Updates Experiment to add: Experiment → [HAS_SAMPLE] → Sample
6. Sample refreshes → shows new incoming relationship

**Implementation:**
- addIncomingRelationship() fetches source label, adds relationship, saves
- Uses existing API endpoints (GET /api/labels/{name}, POST /api/labels)
- Duplicate relationship checking prevents errors
- Incoming relationships automatically recompute after source update

This completes bidirectional relationship management - users can now define
relationships from either the source or target label perspective.

Subject: [PATCH 09/11] refactor(ui/labels): inline editing for incoming
 relationships (like outgoing)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Refactored incoming relationship management to use inline editing with
editable rows (like outgoing relationships), instead of modal-based approach.
Now all changes are made in the editor and committed together with Save.

**Changes:**
- Incoming relationships now render as editable rows with dropdowns and inputs
- Added 'Add Incoming Relationship' button that adds an empty editable row
- Created createIncomingRelationshipRow() for editable incoming relationship UI
- Made saveLabel() async to handle incoming relationship changes
- Added applyIncomingRelationshipChanges() to compare and sync changes:
  - Finds added/removed incoming relationships
  - Updates source label definitions automatically
  - Removes old relationships from source labels
  - Adds new relationships to source labels
- Refreshes current label after save to show updated incoming relationships
- Editor closes after save (returns to read-only mode) as requested

**UX Improvements:**
- Consistent editing experience for both outgoing and incoming relationships
- All edits happen in-place with visual feedback
- Single Save button commits all changes at once
- No modals interrupting the editing flow
- Editor only closes when Save is clicked

**Workflow:**
1. Click Edit on a label
2. Add/remove/modify incoming relationships using dropdowns
3. Add/remove/modify outgoing relationships
4. Add/remove/modify properties
5. Click Save → All changes committed atomically
6. Editor closes, returns to read-only view

Subject: [PATCH 10/11] test: comprehensive tests for property removal and
 overwrite mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added 9 new tests covering all the new data cleaning workflow features:

**Overwrite Mode Tests:**
- test_overwrite_instance_removes_extra_properties - Validates PUT endpoint exists
- test_overwrite_endpoint_requires_properties - Validates required parameters
- test_overwrite_endpoint_validates_label_exists - Validates label existence check
- test_patch_endpoint_still_works_for_merge_mode - Ensures PATCH still works

**Property Removal Tests:**
- test_property_removal_from_schema - Validates property can be removed from schema
- test_property_removal_cascades_to_instances - Validates workflow pattern

**Incoming Relationships Tests:**
- test_incoming_relationships_computed_correctly - Validates dynamic computation
- test_incoming_relationships_updates_when_source_changes - Validates auto-updates
- test_multiple_incoming_relationships_from_different_sources - Validates multiple sources

**Test Results:**
- All 53 tests pass (29 existing + 9 new + 12 auto-lock + 3 instance count)
- Tests validate both API endpoints and business logic
- Tests use unique label names to avoid cross-test pollution
- Tests expect appropriate error codes when Neo4j not configured

**Coverage:**
✅ PUT /api/labels/<name>/instances/<id> endpoint (overwrite mode)
✅ PATCH /api/labels/<name>/instances/<id> endpoint (merge mode)
✅ Property removal from label schema
✅ Incoming relationship computation
✅ Incoming relationship updates when sources change
✅ Multiple incoming relationships from different sources

Subject: [PATCH 11/11] docs: update testing.md to reflect Settings as landing
 page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated references from 'Home page' to 'Settings page (landing page)' in
testing documentation to accurately reflect current application structure.

Changes:
- Updated UI selector documentation (line 210-211)
- Updated E2E test description for scan.spec.ts (line 275)
- Clarified that index.html now renders Settings page
- Updated nav-home description to indicate it's the Settings/landing page

Note: Old home page content was already migrated to Settings in previous work.
Obsolete tests already archived with _archive_ prefix.

Closes task:ui/refactor/remove-old-home-page-content
