* feat(web): adopt SHOC design system and shell layout (ADR 0003) Port shoc-frontend-new dev's design system with its CSS-variable single-token-source mechanism: - src/styles/theme.css: SHOC token file ported verbatim (Montserrat/ DM Sans/JetBrains Mono, primary #1c75bc, navy #262262, full radius/ shadow/sidebar/header token layers); fonts self-hosted via @fontsource - src/lib/theme/{css-vars,mui-theme}.ts: getCssVar -> createTheme adapter mirroring SHOC's mui-theme.ts (palette, typography, shadows tuple, component overrides; MUI v9 slot renames expressed as class selectors); theme.ts is now a re-export - Shell: SHOC composition (sidebar column + sticky gradient topbar + scrolling main); sidebar 244px/76px collapse with brand header row, grouped nav, SHOC active treatment (white card + 3px accent bar); topbar 100-degree gradient, surface hamburger, gradient avatar pill - Brand: SeahavenMark + BrandLockup ported (Tailwind re-expressed as sx; wordmark subtitle localized to PROPOSAL SYSTEM) - Login: SHOC auth-card treatment (centered 384px card on #f9fafb) - Old "Sea Haven Ops" Inter/#2563EB theme and Nunito remnants removed; remaining hardcoded hexes replaced with tokens; lucide-react for shell/nav icons per SHOC convention Verify: tsc clean, 26/26 vitest, vite build OK; Playwright screenshots pixel-sampled against the extracted SHOC spec (all hard values exact, no blocking deviations). * feat(contracts): adopt shared api-contracts in web, add zod schemas and ProblemDetails codes Closes WEB-M5 (web hand-duplicated wire types, standing drift risk): - shared/api-contracts: rewritten as the authoritative superset of the .NET DTOs (ProposalListItem/ProposalDetail with poNumber and submittedByName, line item requests, customers, pricing library, dashboard, audit, sites, auth, presigned upload, ApiProblem); stale Proposal/UpdateLineItemsRequest shapes removed - shared/api-contracts/src/schemas.ts: zod runtime schemas coupled to every wire type via `satisfies z.ZodType<T>` (schema/type drift is now a compile error); separate entrypoint so type-only consumers (mobile) never pull zod - web: imports @proposal-system/api-contracts (file: dep + tsconfig paths + vite preserveSymlinks); all 7 lib/api modules re-export shared types so page imports stay stable; enum unions tightened (PricingLibraryPage form state now ServiceCategory-typed) - fix(web): customer create/update sent a singular `address` field the API silently dropped (contract is addresses: string[], CustomerDtos.cs) - addresses now round-trip, extra addresses preserved on edit - api: ProblemDetails responses carry a machine-readable top-level `code` (SHOC error-code vocabulary): ValidationFailed, InvalidStateTransition, NotFound, Unauthorized, InternalError; new BusinessRuleException(code, message) maps to 422 with its code; GlobalExceptionHandlerTests cover the full mapping (wire contract) Cross-checked .NET DTOs vs TS types vs zod schemas with the orchestrator scanner (Gemini): core domains consistent; internal-only DTOs (FileDtos vendor/lambda surface, SimilarProposalDtos, UserDtos admin surface) intentionally uncovered. Verify: dotnet 166/166, web tsc + vitest 26/26 + build, mobile tsc, shared tsc all green. * feat(web): domain-layer conventions doc + react-hook-form deps (Phase 4 prep) * feat(web): scaffold domain module layer (proposals, lineItems, customers, pricingLibrary, admin, sites) Additive-only: pages still use lib/api/* and constants/queryKeys.ts until the page-migration agents run. Each domain ships api.ts (HTTP moved from lib/api), types.ts (contract re-exports + view types), schemas.ts (contract schema re-exports + form schemas with toRequest mappers), and use-cases.ts (TanStack Query v5 hooks + hierarchical query keys, mirroring current page invalidations and toast-on-error behavior). Adds an explicit vite/vitest alias for the @proposal-system/api-contracts/schemas subpath (package has no exports map) plus a schema/mapper smoke test suite. * refactor(web): proposal pages on domain layer, proposal form on react-hook-form * refactor(web): admin workspace on domain layer * refactor(web): customer management on domain layer + react-hook-form * refactor(web): pricing library on domain layer + react-hook-form * refactor(web): dashboards on domain layer * test(web): domain use-case hook coverage * refactor(web): finish domain-layer integration — migrate straggler components, delete legacy api modules - SimilarProposalsPanel -> useSimilarProposals (domain/admin); inline SimilarProposal type replaced by domain/admin/types (identical shape); query key joins the admin hierarchical key space - LineItemEditor type imports -> domain/lineItems/types - Delete now-orphaned lib/api/{proposals,lineItems,customers, pricingLibrary,admin,sites}.ts, constants/queryKeys.ts, hooks/usePaginatedList.ts (lib/api/client.ts + auth.ts stay per domain README rule 5) Verify: tsc clean, vitest 52/52, build OK, Playwright smoke of the authed shell renders on domain hooks. * fix(web): apply Phase 4 code-review findings (10 correctness + 4 cleanup) Correctness: - State-transition mutations now invalidate every cached view via invalidateProposalViews (detail + line items + lists + stats + admin dashboard) — approving no longer leaves a stale queue for the 5-minute staleTime - Presigned S3 PUT moved to proposals/api.ts with res.ok check — a rejected upload is no longer confirmed as uploaded - toCustomerRequest always sends contactEmail ('' clears); API create path normalizes empty->null to match the update path — customer emails can now be cleared from the UI - Shared Number-based numeric form fields (domain/shared/formFields): '12abc' no longer silently coerces to 12 in the pricing library - Customer create/update invalidate customersKeys.all so cached search autocompletes see new customers - AdminWorkspace clears dirty right after a successful implicit save, before approve — no false unsaved-changes prompt when approve fails - ProposalFormPage submit gate and missing-fields caption derive from ONE checks list (missing customer is now listed) - Empty states gated on !err in ProposalListPage/AdminDashboard — no contradictory error + 'no proposals' UI - VendorDataPanel migrated to useVendorProposals (kills the divergent ['vendorProposals', id] cache key and the inline apiClient query) - useCustomerList/usePricingLibraryList get keepPreviousData — no TablePagination out-of-range flash on page change Cleanup: - Dead speculative hooks removed (useCreate/BulkUpdate/DeleteLineItem, useUpdateProposal, useProposalHistory/Audit, lineItemRowFormSchema, toUpdateLineItemEntry); tests moved to the live save path (useSaveProposalWorkspace) - Shared useDebouncedValue hook replaces 4 drifted inline debounce copies (one leaked its timer on unmount, two hardcoded 300ms); DEBOUNCE_AUTOCOMPLETE=300 named - Fix: WEB-H5 / WEB-H6 finding-ID markers restored at the relocated onError handlers (CLAUDE.md traceability) - shared/api-contracts gains an exports map; /schemas resolver alias deduplicated from 3 copies to the tsconfig paths mapping Verify: tsc clean, vitest 51/51 (tests updated to pin the new invalidation/mapper behavior + new '12abc' rejection test), vite build OK, dotnet 166/166. * refactor(web): fold Redux auth/ui slices into SHOC-shape auth context + storage module Phase 4 tail of the SHOC-alignment plan. Matches SHOC's auth shape (lib/auth storage module + providers/ context split) while keeping the deliberate divergences: - sessionStorage, not localStorage (WEB-C1 stands; SHOC's localStorage is on the SHOULD-NOT-ALIGN list) - token acquisition stays in the auth pages (Cognito code exchange / dev-login) — the provider only owns session state - 401 interceptor clears storage directly (WEB-M2 behavior preserved; full-page redirect resets provider state) Sidebar open state moves to plain layout state in App passed down as props (SHOC (protected)/_layout.tsx pattern), keeping localStorage persistence. Drops @reduxjs/toolkit and react-redux. Tests: authSlice tests replaced by authStorage + AuthProvider suites (QA-C5 coverage preserved); client interceptor tests updated for the storage-based 401 path. 59 vitest green, tsc clean, vite build OK. Verified end-to-end headless: login redirect, seeded-session shell, sidebar toggle persistence, logout, expired/malformed token handling, RoleGuard bounce; recipe persisted as web/.claude/skills/verify. * fix(web): harden auth session teardown per /sh-security-review findings - AUTH-L1 (confirmed medium): logout() now clears the react-query cache — the singleton cache survived SPA logout, serving the previous principal's cached GETs to the next login in the same tab for up to staleTime with no server round-trip. - AUTH-L3 (confirmed low): isTokenValid decodes base64url before atob — valid Cognito JWTs containing '-'/'_' in the payload segment were misclassified as expired (login lockout/loop; inherited from the old authSlice). - AUTH-L2 (unverified, hardened anyway): 401 interceptor broadcasts AUTH_SESSION_CLEARED_EVENT so AuthProvider drops in-memory state synchronously, restoring the old Redux atomic-clear semantics. - INJ-1 (unverified, hardened anyway): Authorization header only set when the stored token is a string. Each fix pinned by a test; 63 vitest green, tsc clean. * docs: web stack row reflects auth-context refactor (Redux removed, MUI v9) * ci(web): Phase 5 — prettier check + Playwright smoke via org frontend workflow Converts the web CI job from ci-typescript-cdk.yaml (typecheck only) to ci-typescript-frontend.yaml: format:check, build (tsc -b included), vitest, and a Playwright chromium smoke. Folds the standalone Web Tests job into it (aggregator needs updated). Pure CI — no AWS secrets. The smoke (e2e/smoke.spec.ts) drives dev-login → dashboard shell → proposal list, plus the unauthenticated bounce, against a fully mocked API (pathname-anchored route interception — a '**/api/**' glob would swallow vite's /src/lib/api/* module URLs). Config mirrors SHOC's playwright.config.ts (port 4173, chromium, dev-server webServer). Prettier: singleQuote + printWidth 100 to match the existing codebase style; lint intentionally not added (no ESLint config yet — run-lint false, out of Phase 5 scope). rollback = revert this workflow file. * style(web): prettier format pass (mechanical) npx prettier --write . with the new .prettierrc (singleQuote, printWidth 100). No functional changes — enforced by format:check in CI from this PR on.

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 (JWT-authorized) with Function URL (AWS_IAM) for internal access
- React 19 Web -- MUI v9 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, Aurora pgvector bootstrap
- CDK Infrastructure -- Three TypeScript stacks managing all AWS resources

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)
Six parallel jobs calling org reusable workflows:
| Job | Workflow | What it checks |
|---|---|---|
| .NET Build & Test | ci-dotnet.yaml |
Restore, build, test the API solution (123 xUnit tests) |
| Web Frontend Check | ci-typescript-frontend.yaml |
Prettier format:check, build (includes tsc -b), vitest suite, Playwright chromium smoke (dev-login → proposal list, API mocked) |
| Mobile Typecheck | ci-typescript-cdk.yaml |
TypeScript typecheck for mobile |
| Python Lint | ci-python-sam.yaml |
ruff check + format on lambdas/ |
| Python Tests | inline job | pytest suite (37 tests — pdf-generate, suggestions, library-ingest, internal API signing) |
| CDK Synth | ci-typescript-cdk.yaml |
Synthesize CDK stacks (includes .NET publish) |
Deploy (manual)
Auto-deploy on push to main is currently disabled (PR #167) — both deploy workflows run via workflow_dispatch from the Actions tab. deploy.yaml calls the cd-cdk.yaml reusable workflow:
- Publishes .NET 8 API and Python Lambdas
- Runs
cdk deploy --all - 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
Workflow: deploy-mobile.yaml -- builds and uploads to TestFlight via cd-mobile-ios.yaml reusable workflow on macos-26.
Trigger: manual only (workflow_dispatch) while the app is pre-V1, to save macOS runner cost.
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) |
Authentication & Authorization
Two-layer auth architecture with defense-in-depth:
| Path | Authorizer | Authentication |
|---|---|---|
External clients → API Gateway /{proxy+} |
Cognito JWT authorizer (web + mobile client IDs) | .NET JWT middleware (ValidateAudience=true) |
/api/health |
None (public) | None |
/api/auth/callback, /api/auth/dev-login |
None (unauthenticated) | None (pre-auth endpoints) |
| Internal Lambdas → Function URL | AWS_IAM (grantInvokeUrl) | Internal API key (X-Internal-Api-Key header, value from Secrets Manager) |
Role-based access: Cognito groups (dispatchers, admins, sysadmins) map to API roles via cognito:groups claim. Dispatchers can only see their own proposals (ownership enforced in service layer). VendorProposals and GeneratedPdfs endpoints restricted to admins/sysadmins.
Internal API key: Python Lambdas call the .NET API via a Lambda Function URL with AWS_IAM auth (bypasses API Gateway JWT check). The InternalApiKeyMiddleware validates the X-Internal-Api-Key header and assigns the admins role to the synthetic identity. Lambdas cache the API key from Secrets Manager with a 5-minute TTL.
Data Flow
- Dispatcher submits proposal request (web or mobile)
- API creates proposal record (with advisory-locked number generation), publishes SQS message
- If vendor PDF attached:
pdf-extractLambda parses and structures data - Suggestions Lambda queries Bedrock KB for similar proposals, generates line items via Claude
- Admin reviews/edits line items in pricing workspace
- On approval:
pdf-generateLambda creates branded PDF - On send:
library-ingestLambda adds approved proposal to KB for future matching
Failed SQS messages are reported via batchItemFailures and retried up to 3 times before moving to the DLQ.
Testing
186 tests across three stacks, all run in CI on every PR:
| Suite | Framework | Count | Coverage |
|---|---|---|---|
| .NET API | xUnit | 123 | State machine transitions, authorization attributes, middleware, validators, ProposalNumberGenerator, LineItemService state guards |
| Web | vitest | 26 | ProtectedRoute, RoleGuard, API client interceptor (401 logout, token attachment) |
| Python Lambdas | pytest | 37 | pdf-generate, suggestions, library-ingest handler contracts, internal API signing |
cd api && dotnet test # .NET tests
cd web && npm test # vitest
cd lambdas && python -m pytest # pytest
Security
Hardening applied across all layers (see AUDIT-REPORT.md for full details):
- Auth: Cognito JWT validation with audience check, startup fails if auth not configured, DevMode gated to
IsDevelopment() - API: FluentValidation on all DTOs, generic error responses (no stack traces or config leaks), structured audit logging with before/after diffs
- Function URL: AWS_IAM auth + internal API key (two-layer defense)
- Infrastructure: S3
enforceSSL+BLOCK_ALL, SQS managed encryption, Aurora in private subnets, Cognito optional TOTP MFA, API Gateway access logging - Lambdas: Prompt injection sanitization, PDF size limits, numeric validation on AI suggestions, S3 key sanitization, idempotent SQS processing
- CI/CD: OIDC (no long-lived credentials), org reusable workflows (
@main),--require-approval broadeningon local deploys - Web: sessionStorage for tokens (not localStorage), error boundaries, role guards on all admin routes, 401 interceptor clears auth state
