+### Folders (`folders`)
+Virtual folder hierarchy for document organization. Folders are database-only entities with no direct relationship to S3 storage locations.

+```sql
+CREATE TABLE folders (
+    id uuid PRIMARY KEY DEFAULT uuid_generate_v7(),
+    path text NOT NULL,

+
+**Key Features**:
+- Self-referential hierarchy via `parentId` for nested folders
+- Client isolation with unique constraint on (clientId, path)
+- Self-reference prevention via check constraint (`id != parentId`)
+- Path column stores virtual folder path (e.g., "/contracts/2025")
+- Folders can be renamed without affecting S3 storage locations
+- Audit tracking via `createdAt` and `createdBy`
+- Note: Added in migration 109

+### Labels System
+
+#### Labels (`labels`)
+Lookup table for document processing status labels.
+
+```sql
+CREATE TABLE labels (
+    label text PRIMARY KEY,
+    description text NOT NULL
+);
+
+-- Seeded initial values
+INSERT INTO labels (label, description) VALUES
+    ('Ingested', 'Document has been ingested into the system'),
+    ('OCR_Processed', 'OCR text extraction completed'),
+    ('GenAI_Processed', 'GenAI processing completed'),
+    ('Doczy_AI_Completed', 'Doczy.AI processing completed'),
+    ('Dashboard_Ready', 'Document ready for dashboard display');
+```
+
+**Key Features**:
+- Predefined processing status labels
+- Primary key on label text for direct referencing
+- Description provides human-readable explanation
+
+#### Document Labels (`documentLabels`)
+Junction table tracking label application to documents.
+
+```sql
+CREATE TABLE documentLabels (
+    id uuid PRIMARY KEY DEFAULT uuid_generate_v7(),
+    documentId uuid NOT NULL,
+    label text NOT NULL,
+    appliedAt timestamp NOT NULL DEFAULT NOW(),
+    appliedBy varchar(255) NOT NULL,

+CREATE INDEX idx_documentlabels_appliedat ON documentLabels(appliedAt);

+
+**Key Features**:
+- Tracks which labels are applied to which documents
+- Audit tracking via `appliedAt` and `appliedBy`
+- Cascade delete removes labels when document is deleted
+- Composite index optimizes queries for most recent label application
+- Multiple applications of same label are allowed (historical tracking)

+## Field Extractions System
+
+The field extractions system stores structured data extracted from documents, supporting both single-value fields (1:1 relationship) and array fields (1:N relationship). This system was added in migrations 112-115.
+
+### Field Extractions Architecture

+
+### Document Field Extractions (`documentFieldExtractions`)
+Stores single-value extracted fields from documents (19 fields total, 1:1 relationship with document).

+
+**Single-Value Fields** (19 fields):
+- **Document identification**: fileName, contractTitle, aareteDerivedAmendmentNum
+- **Party information**: clientName, payerName, payerState, providerState
+- **Tax IDs (as text for leading zeros)**: filenameTin, provGroupTin, provGroupNpi, provGroupNameFull, provOtherTin, provOtherNpi, provOtherNameFull
+- **Contract dates**: aareteDerivedEffectiveDt, aareteDerivedTerminationDt
+- **Renewal info**: autoRenewalInd, autoRenewalTerm
+
+### Document Field Extraction Versions (`documentFieldExtractionVersions`)
+Version tracking for field extractions, enabling historical queries.
+
+```sql
+CREATE TABLE documentFieldExtractionVersions (
+    id uuid PRIMARY KEY DEFAULT uuid_generate_v7(),
+    fieldExtractionId uuid NOT NULL,
+    version bigint NOT NULL,

+    ON documentFieldExtractionVersions(fieldExtractionId);
+CREATE INDEX idx_documentfieldextractionversions_version

+```
+
+**Key Features**:
+- Links field extractions to version numbers
+- Audit tracking via createdBy and createdAt
+- Enables temporal queries and rollback capability
+
+### Document Field Extraction Array Fields (`documentFieldExtractionArrayFields`)
+Stores array-value extracted fields (112 fields total, 1:N relationship with field extraction).

+### Field Extraction Views
+
+#### Current Field Extractions (`currentFieldExtractions`)
+Returns the newest field extraction per document.
+
+```sql
+CREATE VIEW currentFieldExtractions AS
+SELECT DISTINCT ON (dfe.documentId)
+    dfe.id,
+    dfe.documentId,
+    dfe.fileName,
+    dfe.contractTitle,
+    -- ... all single-value fields ...
+    dfev.version,
+    dfev.createdBy,
+    dfev.createdAt
+FROM documentFieldExtractions dfe
+JOIN documentFieldExtractionVersions dfev
+    ON dfev.fieldExtractionId = dfe.id
+ORDER BY dfe.documentId, dfev.id DESC;
+```
+
+**Key Features**:
+- Uses `DISTINCT ON` for efficient latest-per-document queries
+- Joins versions to include version metadata
+- Orders by dfev.id DESC to get most recent version
+
+#### Current Field Extractions With Array Count (`currentFieldExtractionsWithArrayCount`)
+Extends currentFieldExtractions with count of array field rows.
+
+```sql
+CREATE VIEW currentFieldExtractionsWithArrayCount AS
+SELECT
+    cfe.*,
+    COALESCE(array_counts.arraySize, 0) as arraySize
+FROM currentFieldExtractions cfe
+LEFT JOIN (
+    SELECT fieldExtractionId, COUNT(*) as arraySize
+    FROM documentFieldExtractionArrayFields
+    GROUP BY fieldExtractionId
+) array_counts ON array_counts.fieldExtractionId = cfe.id;
+```
+
+**Key Features**:
+- Includes all fields from currentFieldExtractions
+- Adds arraySize column showing count of related array field rows
+- Uses COALESCE for documents with no array fields (returns 0)
+
