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.
BLOCK-10: Add CloudWatch alarms (DLQ, Lambda errors, RDS, API 5xx) with SNS email
BLOCK-11: Remove sync-over-async deadlock in CurrentUserService
BLOCK-12: Add AppDelegate OAuth URL callback handler for mobile
BLOCK-13: Wire mobile 401 interceptor to dispatch Redux logout
BLOCK-14: Fix JWT base64 padding crash and SysAdmin role detection
BLOCK-15: Reset pagination to page 1 on filter change
BLOCK-16: Add unsaved-changes guard (beforeunload + useBlocker) to AdminWorkspace
FIX-08: Add BulkUpdateLineItems FluentValidation validator
FIX-13: Display auth errors on LoginPage
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.
