The web UI shipped as "experimental" and was never finished — no nav
off the dashboard, no live updates, no settled design, never a
supported surface. It was opt-in by default already; leaving the code
in the tree for v0.1.0 only invited "does this work?" questions and
kept HostSummary/BangerSummary/SudoStatus types on the public RPC
surface that nothing else uses.
Removed:
internal/webui/ (all Go + templates + assets)
internal/daemon/web.go (server start / Layout / Config / ListVMs / ListImages)
internal/daemon/dashboard.go (DashboardSummary aggregator)
Simplified:
internal/api/types.go drop WebURL on PingResult, drop
HostSummary / SudoStatus / BangerSummary /
DashboardSummary / DashboardSummaryResult
internal/model/types.go drop DaemonConfig.WebListenAddr
internal/config/config.go drop web_listen_addr from fileConfig + Load
internal/daemon/daemon.go drop webListener / webServer / webURL fields +
startWebServer() call + ping WebURL population
internal/cli/banger.go `daemon status` output no longer branches on web
internal/daemon/{doc.go,ARCHITECTURE.md} drop web UI sections
README.md drop web_listen_addr config bullet + security paragraph
Tests updated to reflect the new shape. Coverage 57.3 -> 58.9% (the
webui package was largely untested; its removal lifts the ratio
without moving the numerator). `banger daemon status` output and
--help are web-free. Lint + full suite green.

// Package daemon hosts the Banger daemon process.
|
|
//
|
|
// The daemon exposes a JSON-RPC endpoint over a Unix socket. It owns VM
|
|
// lifecycle, image management, guest sessions, host networking bootstrap,
|
|
// and state persistence via internal/store.
|
|
//
|
|
// The package is organised into cohesive groups. Pure stateless helpers for
|
|
// each group have been lifted into subpackages; orchestrator methods
|
|
// (Daemon receivers) stay here and compose them.
|
|
//
|
|
// Subpackages:
|
|
//
|
|
// internal/daemon/opstate Generic Registry[T AsyncOp] for async
|
|
// operations (VM create).
|
|
// internal/daemon/dmsnap Device-mapper COW snapshot lifecycle.
|
|
// internal/daemon/fcproc Firecracker process helpers: bridge/tap,
|
|
// binary resolution, PID lookup, wait/kill.
|
|
// internal/daemon/imagemgr Image subsystem helpers: path validation,
|
|
// artifact staging, guest provisioning script
|
|
// generator, metadata.
|
|
// internal/daemon/session Guest-session helpers: state paths, runner
|
|
// / inspect / signal scripts, state snapshot
|
|
// parsing, launch helpers, ShellQuote,
|
|
// FormatStepError.
|
|
// internal/daemon/workspace Workspace helpers: git repo inspection,
|
|
// shallow copy prep, guest-side import,
|
|
// finalize script generation.
|
|
//
|
|
// VM lifecycle (in this package):
|
|
//
|
|
// vm_create.go CreateVM and create-time disk provisioning

|
// vm_set.go SetVM mutation
|
|
// vm_stats.go stats, health, ping, stale reaper

// vm_disk.go system overlay, work disk provisioning

|
|
// vm_locks.go vmLockSet: per-VM mutex set
|
|

|
|
// capabilities.go pluggable capability hooks executed at VM start

|
|
//

|
// vmLocks[id] → {createVMMu, imageOpsMu} → subsystem-local locks
|
|
//
|
|
// Subsystem-local locks live on their owning type (tapPool.mu,
|
|
// sessionRegistry.mu, opstate.Registry mu, guestSessionController.attachMu /
|
|
// writeMu) and do not contend with each other. See ARCHITECTURE.md for
|
