- Add CloudFront origin to API Gateway CORS preflight and .NET CORS policy
- Replace HttpMethod.ANY with explicit methods so OPTIONS preflight doesn't
hit the JWT authorizer (was causing 403 on all API calls)
- Return Cognito ID token instead of access token from auth callback
(access tokens lack the aud claim required by API Gateway JWT authorizer)
- Add CloudFront callback URI to allowed redirect list
- Remove identity_provider=Google from login URL to show Cognito hosted UI
- Replace useBlocker (requires data router) with state-based navigation guard
to fix crash on AdminWorkspace with BrowserRouter
- Add auto-migration on Lambda cold start
- Enable Swagger in production
INF-M1: Replace wildcard anthropic.claude-* foundation-model ARN with the
specific cross-region inference profile ARN and its backing foundation model.
Both suggestions and pdf-extract Lambdas use us.anthropic.claude-sonnet-4-5-20250929-v1:0.
INF-M2: Replace aoss:* data access policy permissions with scoped actions.
KB role gets DescribeCollectionItems/CreateCollectionItems/UpdateCollectionItems
on collection and DescribeIndex/ReadDocument/WriteDocument on indexes.
Index creator gets CreateIndex/DescribeIndex/WriteDocument plus collection describe/create.
INF-M9: Change --require-approval never to --require-approval broadening in
infra/package.json deploy script so IAM/security changes require manual
confirmation during local development.
INF-M5: Add enforceSSL: true to all S3 buckets (uploads, generated,
library, web site) to require HTTPS-only access via bucket policy.
INF-M8: Pin all reusable GitHub Actions workflow references from @main
to commit SHA c040bfaa for supply chain security.
LAM-C1/INF-H1: Change Function URL authType from NONE to AWS_IAM and
grant invokeUrl permission to all four caller Lambdas (suggestions,
pdf-extract, pdf-generate, library-ingest). Lambda HTTP clients will
need SigV4 signing as a follow-up.
INF-H3: Create OpenSearch Serverless VPC endpoint in private subnets
and update network policy from AllowFromPublic to SourceVPCEs, removing
public internet access to the vector search collection.
6-domain audit (API, web, mobile, lambdas, infra, QA) with fixes:
API security: scope internal API key middleware to allowed paths only,
return 401 on invalid key instead of falling through, remove unvalidated
JWT code path, sanitize error messages, add UpdateProposal validator,
remove status field from UpdateProposalRequest to prevent over-posting,
log swallowed exceptions in ProposalService.
Infrastructure: enforce SSL on all S3 buckets, encrypt SQS queues,
enable optional MFA on Cognito, add API Gateway access logging.
Lambdas: fix _retry_request undefined variable across all 4 Lambdas,
re-raise exceptions in pdf-extract/pdf-generate instead of swallowing,
add idempotency guard to suggestions Lambda.
Web: add ErrorBoundary, add auth loading state to ProtectedRoute,
add mutation error toasts in AdminWorkspace, fix dead Cognito link.
Mobile: add mutex to offline queue processing, distinguish permanent
vs retryable failures, register all screens for both roles, log sync
errors.
Swagger/OpenAPI: add Swashbuckle with JWT bearer security definition,
add ProducesResponseType attributes to key endpoints.
Includes AUDIT-REPORT.md with complete findings and CLAUDE.md project
instructions.

FIX-25: Add token refresh with retry queue to mobile API client
FIX-44: Add httpx retry logic to all Lambda handlers
FIX-42/43: Align docker-compose PG version (15) and DB name (proposals) with RDS
BLOCK-01: Add API Gateway JWT authorizer with Cognito, route internal
Lambda calls through Function URL to bypass gateway auth
BLOCK-02/03: Prevent proposal number race condition with pg_advisory_xact_lock
and filter revision numbers from max-number query
BLOCK-04: Restrict VendorProposals and GeneratedPdfs to admins/sysadmins
BLOCK-05: Sum all vendor costs instead of overwriting with single vendor
BLOCK-06: Enable ValidateAudience on JWT, add Auth env vars to API Lambda
BLOCK-07: Validate ID token signature in AuthController via OIDC discovery
BLOCK-08: Use batchItemFailures in all Lambda SQS handlers
BLOCK-09: Increase SQS visibility timeout from 180s to 720s
FIX-10: Scope dispatcher queries to own proposals (IDOR fix)
Apple review requires a test account login path that doesn't depend on
Google OAuth. Add amazon-cognito-identity-js for direct SRP auth with a
native email/password form on the login screen. Fill in the empty Cognito
client ID and pool ID, fix the Cognito domain prefix, and align CDK
callback URLs with the app's actual URL scheme. Enable push-triggered
mobile deploys, add CDK outputs for client IDs, fix stale README
references, and add mobile/README.md.
The log group already exists — created by the compute stack's
logRetention setting on the suggestions Lambda. Adding it to the
foundation stack caused a duplicate resource error on deploy.
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
