Dalang architectureThe panel and API send requests to the gateway and dispatcher, which reads memory and guidance before each turn, keeps its state in SQLite, and spawns Codex CLI or Claude Code sessions that prompt the model providers and call tools and connections. When needed it creates sub-agents that report back, and sends changes to an optional reviewer whose findings come back to the chat.SYS.MAP // DALANGNODES 09 · LINKS 10CONTEXTREQUESTSTATECREATEREPORTCHANGESFINDINGSSPAWNPROMPTTOOL CALL01 · CONTEXTMemory & guidanceProject · personal memoryCode graph · shared skills02 · CHILDSub-agentsSeparate sessionsOptional worktrees03 · REMOTEModel providersOpenAI · AnthropicCalled by the native CLI04 · CLIENTPanel & APIChat · inbox · ChangesPWA · HTTP · MCP clients05 · COREGateway & dispatcherAuth · queues · schedulesFailover · restart / resume06 · CLIAgent runtimeCodex CLI · Claude CodeWorktrees · checkpoints07 · STORESQLite stateChats · events · queuesMemories · approvals08 · CHECKSReview & design checksRead-only reviewerAdvisory design hooks09 · TOOLSTools & connectionsDB / SSH · approvalsExternal MCP serversGrouped capabilities, not separate services.

GEM Platform architectureStaff browsers reach Nginx over HTTPS, which routes each subdomain to one of five business apps: Sales, Project Management, Engineering, Warehouse, and GEM One. Every app signs users in through GEM SSO, which uses Microsoft 365 login. Sales passes won quotations to Project Management, which links to Engineering and Warehouse. The apps store data in PostgreSQL and files in MinIO, and send email through GEM Mailer to external providers. Jenkins deploys the apps once a change passes review, GEM-CRON backs up data to Cloudflare R2, and a read-only chatbot queries PostgreSQL.SYS.MAP // GEM PLATFORMNODES 17 · LINKS 13HTTPSROUTEOAUTHLOGINDATAFILESSENDDEPLOYREAD-ONLYDELIVERBACKUPBUSINESS APPS05 · SALESGEM SMQuotations · pipelineWon quote → PM06 · PROJECTSGEM PMProjects · tasksLinks SM · ENG · WM07 · ENGINEERINGGEM ENGDocument controlRevisions · approvals08 · WAREHOUSEGEM WMPO · inbound · QCOutbound · stock09 · SERVICESGEM OneDriver · room bookingMaintenance requests01 · CLIENTStaff browsersReact SPA per appOne subdomain each02 · EDGENginxReverse proxy · TLSLoopback upstreams03 · IDENTITYGEM SSOOAuth 2.0 code flowRoles per app04 · REMOTEMicrosoft 365Company-domain loginEntra ID tenant10 · DATAPostgreSQLA database per appPrisma migrations11 · FILESMinIOS3 API · evidenceDrawings · attachments12 · MAILGEM MailerBullMQ · Redis queueProvider failover13 · JOBSGEM-CRONDaily DB + file backupsImage compression14 · ASSISTGEM ChatbotRead-only SQLMasked sensitive columns15 · CI/CDJenkinsDeploys after reviewPipeline per repo16 · REMOTEEmail providersBrevo · ResendPostfix relay · DKIM17 · REMOTECloudflare R2Off-site backupsSHA-256 checksumsEach app is React + NestJS + Prisma in Docker Compose.

Umbra architectureThe admin browser reaches the Umbra binary over an SSH tunnel or Nginx, using its API and a server-sent event stream. Umbra keeps its state in SQLite, reads live connections from the kernel's conntrack table, configures WireGuard peers through the kernel module or wireguard-go, and applies nftables rules on a 60-second trial. VPN devices connect to WireGuard over UDP port 51820 and resolve DNS through AdGuard Home, which Umbra manages over its REST API and, when asked, installs through a small root helper.SYS.MAP // UMBRANODES 09 · LINKS 09API · SSESTATEINSTALLREADPEERSUDP 51820RULESREST APIDNS01 · CLIENTAdmin browserSSH tunnel or NginxPhone-friendly panel02 · KERNELconntrackLive connectionsBytes per device03 · CLIENTVPN devicesPhones · laptopsQR or .conf profile04 · STORESQLiteDevices · sessions · logsPure Go · no CGO05 · COREUmbra binaryGo API · embedded UILoopback · CSRF · TOTP06 · TUNNELWireGuardKernel via wgctrlor wireguard-go07 · HELPERRoot helpersystemd path unitInstalls AdGuard Home08 · FIREWALLnftables60-second trialAuto rollback09 · DNSAdGuard HomeListens on the VPN IPFilters · query logOne binary, no Go or Node on the server.
