Workspace packages

apps/web: product-facing web app and control-plane workflows
apps/validation-worker: active validation runtime owned by WC01
packages/shared: shared constants, types, validators, scoring config, and scheduling helpers
packages/web-bot-auth: server-only Web Bot Auth signing and key-directory helpers
packages/db: PostgreSQL query helpers, migrations, seed SQL, and env helpers
packages/ui: reusable UI primitives

Repo boundary

WC01 is now the product/control-plane repo.

product web flows, scan creation, reporting, and validation stay here
the standalone scanner runtime now lives in WS01
scanner operational changes, crawler identity work, and scanner deploy flow should originate in WS01

What the MVP includes

public homepage with preview scan funnel
Better Auth with Google OAuth and email/password login flows
organization bootstrap and protected workspace routes
domain management, plan limits, and client grouping
DB-backed scan creation with scanner-service claiming
crawl/discovery, accessibility, privacy, and legal heuristics
deterministic scoring, canonical report payloads, and authenticated report UI
scanner-generated PDF generation and upload
regression summaries and scheduled rescans
lightweight branding for reports and PDFs

MCP Light

CertScore.ai MCP Light is the free, no-auth, hosted three-tool integration for public website privacy scans. It detects evidence-backed privacy, cookie, tracker, consent, policy, regulatory-review, HTTPS/TLS, and eligible Reject Path post-refusal signals. Results include a CertScore score and supporting evidence for human and agentic review; they are not legal advice, certification, or a compliance determination.

Add CertScore to Cursor · MCP Light landing page · Cursor Directory listing · Agent installation guide · Full installation reference · MCP package guide

Try it with: Use CertScore.ai to review [PUBLIC URL] before launch. Report the CertScore score, evidence-backed findings, Reject Path observations when available, coverage limitations, and the report URL.

Environment variables

This monorepo should use apps/web/.env.local as the single local development runtime env:

copy apps/web/.env.example to apps/web/.env.local

Use .env.example only as a reference template for shared keys. Do not rely on a root .env.local for app runtime configuration.

Recommended environment split inside WC01:

local web + local validation runtime: dedicated dev PostgreSQL database plus S3-compatible storage
production web + production validation runtime: dedicated production PostgreSQL database plus S3-compatible storage

Do not point localhost at the production database or production auth credentials unless you are intentionally testing production behavior.

Required for the web app:

NEXT_PUBLIC_APP_URL
DATABASE_URL
BETTER_AUTH_SECRET
GOOGLE_CLIENT_ID
GOOGLE_CLIENT_SECRET
S3_BUCKET
S3_REGION
S3_ACCESS_KEY_ID
S3_SECRET_ACCESS_KEY

Required for the validation runtime in WC01:

DATABASE_URL
OPENAI_API_KEY

Optional but recommended:

WORKER_CONCURRENCY
PLAYWRIGHT_BROWSERS_PATH
VALIDATION_OPENAI_MODEL
VALIDATION_NANO_MODEL
WEB_BOT_AUTH_ENABLED
WEB_BOT_AUTH_PRIVATE_KEY_PEM
WEB_BOT_AUTH_SIGNATURE_AGENT_URL

Local development setup

Use Node 22, 23, or 24 for local development. Node 20 is below the workspace engine floor, and Node 25 is not supported because it can fail DNS resolution for app routes and external service calls on localhost.

Install dependencies:
- pnpm install
Copy the environment template:
- cp apps/web/.env.example apps/web/.env.local
Start a dedicated PostgreSQL instance for local development.
Apply the SQL migrations from packages/db/migrations.
Seed local development data when needed with packages/db/seed/0001_dev_seed.sql.
Configure Better Auth provider settings:
- Google OAuth if enabled
- email/password and verification settings as needed
Configure auth redirect URLs:
- Google OAuth must allow Better Auth's provider callback route:
- http://localhost:3000/api/auth/callback/google
- http://127.0.0.1:3000/api/auth/callback/google
- https://certscore.ai/api/auth/callback/google
- /auth/callback is only an app alias route; it is not the redirect URI Better Auth initiates with Google
Keep local and production auth isolated:
- local NEXT_PUBLIC_APP_URL should be http://localhost:3000
- local database and auth secrets should come from the dev environment
- production secrets should exist only in the active AWS/web or worker deployment settings
Create the S3-compatible bucket referenced by S3_BUCKET.
Install Playwright Chromium for the validation runtime:

pnpm --filter @website-signal-risk-scanner/validation-worker exec playwright install chromium

Start validation local development with a watched validation worker:

pnpm dev:validation

Start the main local app by itself when needed:

pnpm --filter @website-signal-risk-scanner/web dev

Use WS01 when you need the standalone scanner locally.
Start the standalone scanner locally against the same dev database and storage env as localhost:3000:

pnpm dev:scanner:local

Use the combined local runner only when you want web + validation together in WC01:

pnpm dev:all

Run a validation scheduler sweep manually when needed:

pnpm dev:validation:scheduler

Development verification

Use these commands before shipping changes:

pnpm turbo run typecheck
pnpm turbo run build

Validation-specific checks:

pnpm --filter @website-signal-risk-scanner/validation-worker typecheck
pnpm test:scan-pipeline

The scan pipeline test is deterministic and runs locally from apps/validation-worker/src/validation/pipeline.test.ts.

The normalized concern lifecycle in WC01 is documented in docs/normalized-concern-pipeline.md.

CI validation

GitHub Actions workflow: .github/workflows/accessibility-validation.yml

worker-scan-pipeline-tests runs on pushes to main, pull requests, and manual dispatch. It installs Chromium, typechecks validation-worker, and runs pnpm test:scan-pipeline.
live-validation-smoke runs after the deterministic job and executes pnpm --filter @website-signal-risk-scanner/validation-worker smoke:validation only when the runtime secrets are configured.
If those secrets are missing, the live smoke job is skipped and only the deterministic scan pipeline job runs.

Runtime validation tooling

Use these lightweight checks before first deployment validation:

pnpm dev:storage:local
pnpm --filter @website-signal-risk-scanner/web check-env
pnpm check-env:validation
pnpm --filter @website-signal-risk-scanner/validation-worker check-env
pnpm --filter @website-signal-risk-scanner/validation-worker check-runtime

For local validation runs, pnpm dev:storage:local starts MinIO against the apps/web/.env.local S3 settings and creates the configured bucket when needed. Run it alongside pnpm dev:scanner:local and pnpm dev:validation:worker.

Use this runtime smoke helper:

pnpm --filter @website-signal-risk-scanner/validation-worker scheduler

The full runtime QA sequence is documented in docs/runtime-validation.md. The validation pipeline design and deployment shape are documented in docs/validation-pipeline-plan.md. The validation crawler deployment and VM runbook is documented in docs/validation-ops-runbook.md. Cloudflare Verified Bot setup is documented in docs/cloudflare-web-bot-auth.md.

Web Bot Auth

ConsentCheck can expose a signed HTTP Message Signatures key directory and sign outbound HTTP crawler requests for Cloudflare Verified Bot workflows.

Required configuration:

WEB_BOT_AUTH_ENABLED
WEB_BOT_AUTH_PRIVATE_KEY_PEM
WEB_BOT_AUTH_SIGNATURE_AGENT_URL
WEB_BOT_AUTH_EXPIRES_SECONDS
WEB_BOT_AUTH_INCLUDE_NONCE

Common commands:

pnpm web-bot-auth:generate
pnpm web-bot-auth:print
pnpm web-bot-auth:test-request
pnpm test:web-bot-auth

Production deployment

Web runtime

the live public web deployment target is the AWS ECS/Fargate path for certscore.ai
consentcheck.site is owned outside WC01 and must not be deployed by this repo
main deploys through .github/workflows/web-aws-ecs-deploy.yml
run pnpm ops:check:deploy before or after topology changes to catch stale local assumptions
run pnpm ops:check:live against the public hosts to verify runtime target and revision alignment after deploy
treat docs/aws-web-ecs-cutover-plan.md as the active web deployment runbook
treat docs/deploy-amplify.md as future-state reference material only

Validation And Scanner Runtime

do not use WC01 for the primary scanner deploy path
use WS01 for scanner runtime deployment
keep WC01 deployment guidance scoped to web and validation only
keep web production, validation worker, and scanner runtime as three distinct deployment paths
use the AWS validation deployment lane for WC01 validation runtime changes

Database, Auth, and Storage

create production PostgreSQL, Better Auth, and S3-compatible storage resources separate from local development
apply all migrations in order
configure the production site URL and production redirect URLs only
create the report storage bucket referenced by S3_BUCKET

Scheduler

Recommended production trigger:

run the validation scheduler sweep every hour if the validation runtime is enabled

Command:

pnpm dev:validation:scheduler

The primary scanner scheduler now lives in WS01.

Deployment readiness checklist

Environment variables configured
PostgreSQL database created
database migrations applied
Better Auth providers configured
S3-compatible storage bucket created
Playwright browsers installed
Worker process running
Scheduler cron configured
First domain scanned successfully
Report generated successfully
PDF export generated successfully

First production validation

After deployment, validate in this order:

run the env and runtime checks above
verify login and organization bootstrap
verify preview scan flow
verify full scan completion
verify findings, scores, and report persistence
verify PDF export
verify regression on a second scan
verify the hourly scheduler sweep path

Operational notes

The standalone scanner in WS01 owns crawl, auditing, scoring, reporting, PDF generation, and scheduled sweep logic.
PDF generation failures do not invalidate the scan or web report.
Regression calculation failures do not invalidate the scan or report.
The app validates critical env vars at runtime and now fails fast with clearer messages when required configuration is missing.
