Introduces per-company reusable NCalc2 pricing formula templates for complex
fabricated items (roof curbs, enclosures, welded frames). Templates support
two output modes — FixedRate (formula yields a dollar amount) and SurfaceAreaSqFt
(formula yields sq ft fed into the standard coating engine). Includes:
- CustomItemTemplate entity, migration (AddCustomItemTemplates), IUnitOfWork repo
- IsCustomFormulaItem / CustomItemTemplateId / FormulaFieldValuesJson flags on
QuoteItem, JobItem, CreateQuoteItemDto; mapped in all 3 JobItemAssemblyService
overloads and all existingItemsData JSON projections + pageMeta blocks
- ICustomFormulaAiService / CustomFormulaAiService: Claude-powered formula
generator (natural language + optional diagram image) and NCalc2 evaluator
- CompanySettings CRUD endpoints: GetCustomItemTemplates, Create/Update/Delete,
UploadTemplateDiagram, TemplateDiagram (blob serve), EvaluateFormula, GenerateFormulaFromAi
- Company Settings "Custom Formulas" tab + cfModal + company-settings-custom-formulas.js
- item-wizard.js: formula item type card, renderFormulaFields, wzFormulaRecalc
(live evaluate via POST), collectStep2 formula branch, buildCardHtml / emitHiddenFields
- Formula badge in Quotes/Details and Jobs/Details; AI badge gap fixed in Jobs/Details
- Help article (CustomFormulaTemplates.cshtml), Help Index card, HelpController action,
HelpKnowledgeBase entry; 225/225 unit tests passing

Replaces the local filesystem path (which required IIS app pool write
access to inetpub\wwwroot\DataProtection-Keys) with SQL Server storage
via IDataProtectionKeyContext. Keys now survive deploys and IIS recycles
without any server-side folder permission setup.
Production continues to use Azure Blob Storage unchanged.
- Add Microsoft.AspNetCore.DataProtection.EntityFrameworkCore 8.0.11 to
Web and Infrastructure projects
- ApplicationDbContext implements IDataProtectionKeyContext
- Migration AddDataProtectionKeys creates DataProtectionKeys table
- Program.cs: non-production path uses PersistKeysToDbContext

Each catalog item now supports one optional image (jpg/jpeg/png/gif/webp,
max 10 MB). Uploading generates a 200x200 JPEG thumbnail automatically via
SixLabors.ImageSharp. Images are stored in Azure Blob Storage under a new
catalogimages container, keyed by {companyId}/catalog/{itemId}/.
- CatalogItem entity: ImagePath + ThumbnailPath (nullable string fields)
- Migration: AddCatalogItemImages applied
- ICatalogImageService / CatalogImageService: upload, thumbnail generation,
delete; old blobs replaced atomically on re-upload
- CatalogItemsController: Create/Edit accept optional IFormFile image;
Image(id, thumbnail) action serves blobs with [Authorize] so wizard users
can load thumbnails without CanManageProducts policy
- Catalog index (_CategoryNode): 40x40 thumbnail (or placeholder icon)
left of each item name
- Details view: image card in right column with click-to-full-size link
- Create/Edit views: file picker with live preview; Edit shows current
thumbnail with Remove checkbox
- Wizard (item-wizard.js): thumbnails in product list with hover preview
that follows the cursor (showCatalogPreview / moveCatalogPreview);
fixed Bootstrap d-flex !important bug that broke the filter box by
moving flex layout to an inner wrapper div
