feat: MyEasyCMS v2 — Full SaaS rebuild
Complete rebuild of 22-year-old PHP CMS as modern SaaS:

Database (15 migrations, 42+ tables):
- Foundation: account_settings, audit_log, GDPR register, cms_files
- Module Engine: modules, fields, records, permissions, relations + RPC
- Members: 45+ field member profiles, departments, roles, honors, SEPA mandates
- Courses: courses, sessions, categories, instructors, locations, attendance
- Bookings: rooms, guests, bookings with availability
- Events: events, registrations, holiday passes
- Finance: SEPA batches/items (pain.008/001 XML), invoices
- Newsletter: campaigns, templates, recipients, subscriptions
- Site Builder: site_pages (Puck JSON), site_settings, cms_posts
- Portal Auth: member_portal_invitations, user linking

Feature Packages (9):
- @kit/module-builder — dynamic low-code CRUD engine
- @kit/member-management — 31 API methods, 21 actions, 8 components
- @kit/course-management, @kit/booking-management, @kit/event-management
- @kit/finance — SEPA XML generator + IBAN validator
- @kit/newsletter — campaigns + dispatch
- @kit/document-generator — PDF/Excel/Word
- @kit/site-builder — Puck visual editor, 15 blocks, public rendering

Pages (60+):
- Dashboard with real stats from all APIs
- Full CRUD for all 8 domains with react-hook-form + Zod
- Recharts statistics
- German i18n throughout
- Member portal with auth + invitation system
- Public club websites via Puck at /club/[slug]

Infrastructure:
- Dockerfile (multi-stage, standalone output)
- docker-compose.yml (Supabase self-hosted + Next.js)
- Kong API gateway config
- .env.production.example

gitnexus-debugging Use when the user is debugging a bug, tracing an error, or asking why something fails. Examples: "Why is X failing?", "Where does this error come from?", "Trace this bug"

Debugging with GitNexus

When to Use

  • "Why is this function failing?"
  • "Trace where this error comes from"
  • "Who calls this method?"
  • "This endpoint returns 500"
  • Investigating bugs, errors, or unexpected behavior

Workflow

1. gitnexus_query({query: "<error or symptom>"})            → Find related execution flows
2. gitnexus_context({name: "<suspect>"})                    → See callers/callees/processes
3. READ gitnexus://repo/{name}/process/{name}                → Trace execution flow
4. gitnexus_cypher({query: "MATCH path..."})                 → Custom traces if needed

If "Index is stale" → run npx gitnexus analyze in terminal.

Checklist

- [ ] Understand the symptom (error message, unexpected behavior)
- [ ] gitnexus_query for error text or related code
- [ ] Identify the suspect function from returned processes
- [ ] gitnexus_context to see callers and callees
- [ ] Trace execution flow via process resource if applicable
- [ ] gitnexus_cypher for custom call chain traces if needed
- [ ] Read source files to confirm root cause

Debugging Patterns

Symptom GitNexus Approach
Error message gitnexus_query for error text → context on throw sites
Wrong return value context on the function → trace callees for data flow
Intermittent failure context → look for external calls, async deps
Performance issue context → find symbols with many callers (hot paths)
Recent regression detect_changes to see what your changes affect

Tools

gitnexus_query — find code related to error:

gitnexus_query({query: "payment validation error"})
→ Processes: CheckoutFlow, ErrorHandling
→ Symbols: validatePayment, handlePaymentError, PaymentException

gitnexus_context — full context for a suspect:

gitnexus_context({name: "validatePayment"})
→ Incoming calls: processCheckout, webhookHandler
→ Outgoing calls: verifyCard, fetchRates (external API!)
→ Processes: CheckoutFlow (step 3/7)

gitnexus_cypher — custom call chain traces:

MATCH path = (a)-[:CodeRelation {type: 'CALLS'}*1..2]->(b:Function {name: "validatePayment"})
RETURN [n IN nodes(path) | n.name] AS chain

Example: "Payment endpoint returns 500 intermittently"

1. gitnexus_query({query: "payment error handling"})
   → Processes: CheckoutFlow, ErrorHandling
   → Symbols: validatePayment, handlePaymentError

2. gitnexus_context({name: "validatePayment"})
   → Outgoing calls: verifyCard, fetchRates (external API!)

3. READ gitnexus://repo/my-app/process/CheckoutFlow
   → Step 3: validatePayment → calls fetchRates (external)

4. Root cause: fetchRates calls external API without proper timeout
