FIX-10: Scope dispatcher queries to own proposals (IDOR fix)
oss-index-creator Lambda was missing functionName, arm64 architecture,
and explicit log retention — all required by the engineering handbook.
CI workflow was not passing node-version to reusable workflows, risking
drift. Removed unused _api_request helper from all four main Lambdas.
Added missing suggestions log group to foundation stack.
The Bedrock Knowledge Base creation was failing with 403/404 because
the OpenSearch Serverless data access policy hadn't propagated before
the KB tried to connect. Adds a CDK Custom Resource (using opensearch-py)
that creates the vector index with retry logic, ensuring the full
dependency chain: Collection → DataAccessPolicy → Index → KnowledgeBase.
* Fix NuGet versions and add InitialCreate EF Core migration
- Update AWSSDK.SQS and AWSSDK.SecretsManager to 3.7.500.0 (actual available versions)
- Update AWSSDK.Extensions.NETCore.Setup to 3.7.400
- Generate InitialCreate migration for PostgreSQL (all 8 entities)
- Build verified: 0 errors, 0 warnings
* Implement Dispatcher Frontend (Phase 2)
React 19 + MUI v7 + TypeScript + Vite SPA matching SHOC patterns:
Redux Toolkit (auth/ui slices), TanStack React Query, axios interceptors,
react-toastify, Cognito OAuth PKCE login flow, paginated proposal list,
new proposal form with customer autocomplete and vendor PDF upload,
read-only proposal detail with status stepper timeline.
* Add AuthController for Cognito code exchange and .env.example
Backend endpoint POST /api/auth/callback exchanges the OAuth
authorization code with Cognito's token endpoint, auto-provisions
the user in the DB, and returns the access token to the frontend.
* Implement Admin Frontend Experience (Phase 3)
Three-panel admin workspace: left reference panel (submission details,
vendor data), center editor (refined scope, inline line item table with
reorder/add/remove/pricing), right similar proposals panel (KB results
with pull-to-editor). Admin dashboard with stats cards and proposal
queue table. Approval flow with confirmation dialog, mark-as-sent,
and create-revision actions. Role-based sidebar navigation.
* Implement backend dev mode, internal API auth, and service layer enhancements
- Add dev-login endpoint with local JWT signing for local development
- Add InternalApiKeyMiddleware with timing-safe comparison for Lambda-to-API auth
- Add DevS3Service and NoOpJobPublisher for running without AWS services
- Implement CurrentUserService cascading user resolution (ID → sub → email → create)
- Add async ResolveAsync() to avoid synchronous DB calls in request pipeline
- Add /proposals/stats endpoint for efficient server-side status counts
- Guard status transitions: only allow Draft → InReview via update endpoint
- Add vendor proposals, generated PDFs, and similar proposals controllers
- Add ISimilarProposalService and SimilarProposalService
- Add [Authorize] to AddSimilarReference endpoint
* Implement Lambda functions for PDF processing, suggestions, and library ingest
- pdf-extract: Parse vendor PDFs with pdfplumber, fallback to Claude multimodal
- pdf-generate: Generate branded proposal PDFs with reportlab Platypus
- library-ingest: Format approved proposals as markdown and sync to Bedrock KB
- suggestions: Query KB for similar proposals, generate line items via Claude
- All Lambdas use internal API key auth and cold-start secret caching
- Fix pdf_path unbound variable in pdf-extract error handling
* Add Bedrock Knowledge Base, OpenSearch Serverless, and SQS message filtering
- Provision OpenSearch Serverless collection for vector search
- Create Bedrock Knowledge Base with Titan embedding model
- Configure S3 data source with fixed-size chunking (512 tokens, 20% overlap)
- Add suggestions Lambda with SQS event source filtering
- Scope bedrock:InvokeModel IAM to specific model ARN patterns
- Add internal API key secret in Secrets Manager
- Add log retention (2 months) to all Lambda functions
- Add docker-compose.yml for local PostgreSQL
* Apply SHOC design system styling across frontend
- Rewrite theme with SHOC palette (#0c4f6f primary, Nunito font, 4px radius)
- Add global CSS with Google Fonts import for Nunito
- Redesign Topbar with avatar initials, role subtitle, gradient header
- Redesign Sidebar with 220px width, section headers, active state border
- Restyle LoginPage with SHOC branded card and dev-mode role selector
- Update AdminDashboard KPI cards to centered SHOC style
- Add devLogin API method for local development auth flow
* Fix frontend navigation bugs, differentiate Dashboard from Proposals list
- Fix double nav selection by adding isNavActive() with ALL_NAV_PATHS set
- Fix /admin/users routing to placeholder instead of redirect to /
- Fix ProposalDetailPage Back button navigating to / instead of /proposals
- Differentiate Dashboard (KPI cards + recent 5) from ProposalListPage (full paginated table)
- Dashboard now uses dedicated /proposals/stats endpoint for accurate counts
- Fix adminApi.getPdf dead code (axios rejects before status check)
- Wire up PDF generation button in AdminWorkspace
- Adjust layout: 220px drawer, 10px content padding, 64px toolbar height
* Add appsettings.Development.json to gitignore
Prevent dev-only signing keys and connection strings from being committed.
* Fix CI failures: unused Python imports and CDK synth asset path
CDK synth job needs the .NET API published first so the Lambda asset
path exists. Python lint had 3 unused imports in pdf-generate.
* Apply ruff formatting to all Lambda Python files
