- API-M2: Add comment for fail-loud auth config guard (already implemented)
- API-M5: Add FluentValidation validators for VendorProposal, GeneratedPdf,
and SimilarReference DTOs; move request records to Application DTOs
- API-M7: Add AsNoTracking() to all read-only queries in ProposalService,
LineItemService, AdminController, UsersController, FilesController
- API-M9: Log stderr from dev PDF generation instead of returning to client
- API-M10: Return generic "Authentication service unavailable" in auth
callbacks instead of leaking Cognito/DevMode configuration state
- API-M12: Enrich audit logging with before/after values for status changes,
proposal edits, and line item operations using structured JSON
- API-M13: Log previous role alongside new role on user role changes in
both UsersController and Cognito-synced role updates in AuthController
AdminController: Rewrite avgTurnaround query to fetch approved times to
memory before computing TotalHours — EF Core/Npgsql cannot translate
TimeSpan.TotalHours to SQL, causing a 409 on every dashboard load.
ProposalService.ReviseAsync: Append -R{n} suffix to revision's
ProposalNumber so it doesn't violate the unique index. Previously copied
the parent's number verbatim, causing a DbUpdateException (500).
ProposalService Update/Approve/MarkSent: Add .Include(p => p.SubmittedBy)
(and ApprovedBy where relevant) so MapToResponse returns submittedByName
instead of null. GetByIdAsync already had these includes.
