+## Agent Swarm Execution Plan — Wave 1 (in progress)
+
+Leadership Goal: stabilize builds and payments without behavior regressions; reduce false security failures; preserve MCP areas.
+
+Completed (safe changes)
+- Stripe client pin removed to avoid runtime rejections
+  - lib/supabase/services/payments.ts:516
+  - lib/supabase/services/StripeWebhookHandler.ts:32
+  - lib/supabase/services/stripeCustomer.ts:26
+- Prevent client bundle from importing server‑only Stripe helper
+  - lib/supabase/services/payments.ts:13, lib/supabase/services/payments.ts:451
+- Defensive checkout guards for previews/misconfig
+  - lib/supabase/services/payments.ts:411, lib/supabase/services/payments.ts:520
+- Fix secret scan grep option bug (false positives reduced)
+  - scripts/check-secrets.sh: lines with grep pattern args
+- CSRF origin validation respects reverse proxy headers
+  - lib/csrf.ts: validateOrigin()
+- Netlify plugin bump per build hint
+  - package.json: devDependencies
+
+Build/Deploy Checklist (Netlify)
+- Confirm stripe envs present in desired contexts
+  - STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET
+  - STRIPE_PRICE_ID_STARTER/CORE/PRO/ELITE/PREMIUM as used
+  - ENABLE_PAYMENT_PROCESSING = "true" only where real charges are desired
+- Re‑deploy (build uses npm ci && npm run build:production)
+  - Expect no module‑not‑found for './stripeCustomer'
+  - Previews continue in test‑mode if payments disabled or misconfigured
+
+Wave 2 (proposed, non‑breaking)
+- Tests triage (focus set 1)
+  - Align emails tests ordering vs implementation or extend service to accept explicit orderBy param (default unchanged)
+  - Align authorization middleware test message expectations to current semantics
+- Authorization policy coverage to 100%
+  - Add missing policies for: emails (sendContactFormEmail), testimonials (getApproved, getPublicTestimonials), intakePayments (list, getAllIntakePayments), paymentAttempts (list, getAllPaymentAttempts), ceuCourses (list, getAllCourses, getAvailableCourses)
+- Lint/Type hygiene
+  - Address top exhaustive‑deps warnings and localized any hotspots; keep functional behavior
+- Secret scanning
+  - Optionally adopt gitleaks with tuned config and directory ignore set; keep current script as fast preflight
+
+Verification after Wave 2
+- Run: npm run validate, npm run build
+- Execute focused unit suites for modified areas (emails/middleware)
+- Trigger Netlify preview deploy and perform smoke checks (checkout creation path, CSRF‑guarded APIs)
+
+Notes
+- MCP‑related files remain untouched by design.
+- All changes are defensive or build‑only; app behavior preserved in production contexts.
