Add iOS CD pipeline and refactor workflows to org reusable callers (#24) 
* Add iOS native project for React Native mobile app

Xcode project with bundle ID com.seahavenind.proposals,
CocoaPods configuration, and app scaffolding.

* Add Fastlane configuration for iOS builds and TestFlight distribution

Configures match with S3 storage (seahaven-ios-certificates bucket)
for code signing and a beta lane for automated TestFlight uploads.

* Add mobile CI job and iOS CD workflow (disabled)

CI: adds mobile typecheck job on PRs.
CD: deploy-mobile.yaml builds and uploads to TestFlight via
Fastlane on a macOS runner with OIDC auth for match S3 access.
Currently workflow_dispatch only — activate for V1 release.

* Refactor workflows to thin wrappers calling org reusable workflows

CI jobs now call ci-dotnet, ci-typescript-cdk, and ci-python-sam
from the org repo. Deploy calls cd-cdk with post-deploy script
for web build/S3/CloudFront. Mobile deploy calls cd-mobile-ios.
Adds deploy concurrency groups to both deploy workflows.

* Add mobile Dependabot entries and remove assignees

Add npm and bundler ecosystems for mobile/. Remove assignees
from all entries — convention no longer in use.

* Add comprehensive README for the proposal-system monorepo

* Fix mobile TypeScript errors and add package-lock.json

Fix tsconfig.json (remove rootDir/outDir, add noEmit), fix useRef
type error, fix navigation type cast, add @types/react-native-vector-icons,
and generate package-lock.json for CI.

* Add .npmrc for mobile to resolve peer dependency conflicts

react-native-screens@4.x requires react-native >= 0.82 but the
project uses 0.79. legacy-peer-deps allows installation until
the next React Native upgrade.

Proposal System

Internal proposal management platform for Sea Haven Industries. Dispatchers submit proposal requests, AI generates draft line items from historical data via Bedrock RAG, admins review and approve in a pricing workspace, and the system produces branded PDFs for delivery.

Architecture Overview

Monorepo with five primary services:

  • .NET 8 API -- Clean Architecture REST API hosted on Lambda behind API Gateway
  • React 19 Web -- MUI v7 admin/dispatcher workspace served via CloudFront + S3
  • React Native Mobile -- iOS-first field app for dispatchers (offline-capable)
  • Python Lambdas -- PDF extraction, PDF generation, library ingestion, AI suggestions
  • CDK Infrastructure -- Three TypeScript stacks managing all AWS resources

AWS Resources

All resources are in us-east-1 (account 328440206208). CDK stacks are defined but not yet deployed to AWS.

CDK Stack Key Resources
proposal-system-foundation RDS PostgreSQL 15 (t4g.small), S3 buckets, SQS queue + DLQ, Cognito user pool, Secrets Manager
proposal-system-compute API Gateway HTTP API, .NET 8 API Lambda, Python Lambdas (pdf-extract, pdf-generate, library-ingest, suggestions), Bedrock KB
proposal-system-frontend CloudFront distribution (S3 OAC)
Resource Type Names
S3 Buckets proposal-system-uploads, proposal-system-generated, proposal-system-library, seahaven-ios-certificates
SQS proposal-system-jobs + proposal-system-jobs-dlq (message body filtering by jobType)
Secrets proposal-system/db-credentials, proposal-system/internal-api-key

Local Development

Prerequisites

  • .NET 8 SDK
  • Node.js 24+
  • Python 3.12
  • PostgreSQL 16 (via docker-compose or native)

Database

docker compose up -d    # starts PostgreSQL on port 5432
# database: proposalsystem, password: localdev

API

cd api
dotnet restore
dotnet run --project src/ProposalSystem.Api
# runs on http://localhost:5000

In development mode (DevMode=true in appsettings.Development.json):

  • JWT auth uses a local symmetric HMAC key (no Cognito required)
  • S3 service returns fake presigned URLs
  • SQS publisher logs messages without sending

Web Frontend

cd web
npm install
npm run dev
# runs on http://localhost:5173, proxies /api to localhost:5000

When VITE_COGNITO_CLIENT_ID is not set, the login screen shows role-selector buttons for local development.

Infrastructure

cd infra
npm install
npx cdk synth

CI/CD

CI (on pull request to main)

Five parallel jobs calling org reusable workflows:

Job Workflow What it checks
.NET Build & Test ci-dotnet.yaml Restore, build, test the API solution
Web Frontend Check ci-typescript-cdk.yaml TypeScript typecheck for web
Mobile Typecheck ci-typescript-cdk.yaml TypeScript typecheck for mobile
Python Lint ci-python-sam.yaml ruff check + format on lambdas/
CDK Synth ci-typescript-cdk.yaml Synthesize CDK stacks (includes .NET publish)

Deploy (on push to main)

Calls cd-cdk.yaml reusable workflow:

  1. Publishes .NET 8 API and Python Lambdas
  2. Runs cdk deploy --all
  3. Executes scripts/post-deploy.sh (builds web, syncs to S3, invalidates CloudFront)

Deploy uses OIDC role githubdeploy-proposal-system. Concurrency group prevents parallel deploys.

Mobile Deploy (currently disabled)

Workflow: deploy-mobile.yaml -- triggered by workflow_dispatch only (manual).

To activate for release, change the trigger to push on main with path filter mobile/**.

Mobile iOS

The iOS app uses Fastlane with match for code signing. Certificates and profiles are stored in the seahaven-ios-certificates S3 bucket (versioning enabled, public access blocked).

Build and upload to TestFlight is handled by the cd-mobile-ios.yaml reusable workflow. Required secrets:

Secret Purpose
AWS_DEPLOY_ROLE_ARN OIDC role for match S3 access
MATCH_PASSWORD Decryption passphrase for signing assets
ASC_KEY_ID App Store Connect API key ID
ASC_ISSUER_ID App Store Connect issuer
ASC_KEY_CONTENT App Store Connect API key (base64)

To activate automatic deploys, update deploy-mobile.yaml trigger from workflow_dispatch to:

on:
  push:
    branches: [main]
    paths: ["mobile/**"]

Data Flow

  1. Dispatcher submits proposal request (web or mobile)
  2. API creates proposal record, publishes SQS message
  3. If vendor PDF attached: pdf-extract Lambda parses and structures data
  4. Suggestions Lambda queries Bedrock KB for similar proposals, generates line items via Claude
  5. Admin reviews/edits line items in pricing workspace
  6. On approval: pdf-generate Lambda creates branded PDF
  7. On send: library-ingest Lambda adds approved proposal to KB for future matching
