Master Map — System Architecture (CTO View)
This is the master map of your full system from a CTO viewpoint: what exists, what talks to what, what is system-of-record, and where automation/knowledge live.
Legend: ✅ = already exists in some form; 🧭 = planned/iterating; ❓ = needs decisions.
1) North Star (why this architecture exists)
Outcomes
- Product-centric execution: one CRM/PM platform that supports all products (not just SCOMM)
- AI-driven workflows per product: customizable agent flows depending on product type (LoRaWAN, RFID, firmware-only, etc.)
- Repeatable deployments (gateways, servers, dashboards)
- Faster engineering cycles (templates + prompts + gates + auto-generated firmware scaffolds)
- Traceability for R&D + implementation: decisions, checklists, evidence, ownership, status
- Lower ops cost (automation + observability)
- Team scalability (tutorial tracks + KB + standard workflows)
2) System context map (everything at once)

3) Layered architecture (how it should be organized)

L4["L4 — Knowledge/Automation\n• Docusaurus KB\n• prompts\n• OpenClaw automation\n• CI"]
L0 --> L1 --> L2 --> L3 --> L4
Design principle: keep L0/L1 device-specific complexity out of L2/L3 by enforcing standard protocols and idempotent event contracts.
4) Core subsystems (CTO modules)
4.1 Home Lab Infra (Proxmox) ✅
Purpose: repeatable VM creation for stacks like ChirpStack.
- Proxmox host:
10.10.9.100 - Template VM: Ubuntu cloud-init template (VMID 9000)
- VM provisioning: static IP, ssh keys, no snippet reliance
4.2 LoRaWAN Edge Stack (ChirpStack per gateway) ✅
Purpose: each gateway runs its own ChirpStack instance.
- Docker compose deployment
- UDP/1700 for packet forwarder
- (Optional) Basic Station later if needed
4.3 RFID ETS ✅
Purpose: bundle-level tracking with stations.
- Station firmware: ESP32 + RFID + LCD/touch + LED/buzzer
- Backend: Express + Postgres
- Admin UI: mapping/monitoring
4.4 CRM / Project Manager (SPM) 🧭
Purpose: becomes system-of-record for:
- customers / sites
- inventory
- deployments
- device registry
- support tickets
- SOP/runbook links
4.5 Digital Library (Docusaurus KB) ✅
Purpose: durable memory + team onboarding.
docs/projects/*project runbooksdocs/prompts/*reusable promptsdocs/templates/*templates
4.6 Agent Automation (OpenClaw) ✅→🧭
Purpose: execute the playbooks.
- node-based takeovers
- scheduled checks/reminders
- generate docs + prompts + scaffolds
5) System-of-record and contracts (the most important CTO decision)
Recommended system-of-record boundaries (product-centric)
- Unified CRM/PM (SPM) is the truth for:
- Product catalog (products, versions, BOM refs, firmware baseline)
- Customer / Site / Deployment
- Inventory (gateway SKU, sensor SKU, spares)
- Work execution (tasks, checklists, owners, evidence, approvals)
- Automation runs (what ran, when, by which agent, outputs)
- ChirpStack is the truth for: LoRaWAN identities/keys + device sessions.
- RFID backend is the truth for: Bundles, RFID events, station mapping.
- Digital Product Library (Docusaurus KB) is the truth for: runbooks, architecture, SOPs, troubleshooting, postmortems.
Contracts (interfaces) to standardize
- Station → Backend event ingest: idempotent event IDs, auth tokens.
- Gateway → ChirpStack: UDP/1700 packet forwarder baseline (document ports, NAT rules, time sync).
- CRM → Automation: a versioned Execution Spec object that can drive:
- repo bootstrap
- firmware scaffold generation
- infra provisioning
- stack deployment
- verification checks
- Automation → CRM: writeback of status + evidence links + logs.
- Notifications Engine → Messaging: rule-based alert routing + escalation (WhatsApp, email, etc.).

%% Notes:
%% - CHIRPSTACK_DEVICE can be mirrored or linked.
%% - EXECUTION_FLOW is your “AI-driven product workflow”.
CTO decision (recommended): keep a unified Device Registry inside CRM with links out to ChirpStack and RFID identities, so you can drive automation + traceability from one place.
7) Network boundary map (refined)
Chosen: station→backend is LAN only. ChirpStack long-term is hybrid.

9) Confirmed decisions
- ✅ Unified Device Registry in CRM/PM: YES
Confirmed architecture choices (from Arif)
- CRM strategy: A — Replace SCOMM (SPM becomes the unified platform)
- ChirpStack long-term: C — Both (hybrid) — central is read-only (analytics/backup), site-local is authoritative
- Station→backend transport: A — LAN only (site-local)
- Dashboards: C — Both (Docusaurus + A2UI dashboards)
10) Next deliverables (now that registry=YES)
I will produce:
- a refined master map emphasizing the Unified Device Registry as the control plane
- a “System Contracts” page listing exact APIs/topics/ports/events
- a prioritized automation backlog (top 20 tasks)
