The architecture/code map previously lived in .claude/CLAUDE.md, which was
gitignored (local-only) and auto-loaded into every agent session alongside
the root CLAUDE.md. Track it in docs/architecture.md instead and reference
it from CLAUDE.md so it is read on demand.
While moving it, fact-check the whole map against the current tree:
- add the missing internal/eventbus and internal/tunnelmonitor packages,
the service/email subpackage, and util/wirecodec
- document node mTLS (tls_client.go, node_mtls.go, setting_mtls.go) and the
fourth TLS verify mode
- add the Host, ClientExternalLink, NodeClientIp and ClientGlobalTraffic
models plus their symptom-index rows
- correct the cron table (check_cpu_usage is 1m not 10s; add
check_memory_usage and free_os_memory), the middleware chain
(MaxBodyBytes, ConfigEnvelope, CSRF) and the controller route prefixes
- refresh the sub/ and service/ file listings, frontend pages (hosts/,
index/), CI workflow list, and replace stale exact line counts with
rounded sizes
