Install Docker in experimental Void images
Make the local-only void-exp rootfs useful as a dev VM baseline by baking Docker and Compose into the XBPS package set instead of leaving container setup to manual follow-up.

Enable the docker runit service during image assembly, add a small boot preflight that loads the needed netfilter/overlay modules and applies the Docker sysctl file before dockerd starts, and keep the Void cleanup path removing caches, docs, and stale get-docker artifacts.

Refresh the README and repo guidance to describe Docker as part of the current Void image contract and to remind users that they need to rebuild and recreate Void VMs to pick it up.

Verified with bash -n make-rootfs-void.sh and git diff --check for the touched files. I did not run a live make rootfs-void or boot a fresh Void VM in this pass.

Add experimental Void guest workflow and vsock agent
Make iterating on a Firecracker-friendly Void guest practical without replacing the Debian default image path.

Add local Void rootfs build/register/verify plumbing, a language-agnostic dev package baseline, and guest SSH/work-disk hardening so new images use the runtime bundle key, keep a normal root bash environment, and repair stale nested /root layouts on restart.

Replace the guest PING/PONG responder with an HTTP /healthz agent over vsock, rename the runtime bundle and config surface from ping helper to agent while still accepting the legacy keys, and route the post-SSH reminder through the new vm.health path.

Validated with GOCACHE=/tmp/banger-gocache go test ./..., make build, bash -n customize.sh make-rootfs-void.sh, and git diff --check.

Speed up VM create with work seeds
Beat VM create wall time without changing VM semantics.

Generate a work-seed ext4 sidecar during image builds and rootfs rebuilds, then clone and resize that seed for each new VM instead of rebuilding /root from scratch. Plumb the new seed artifact through config, runtime metadata, store state, runtime-bundle defaults, doctor checks, and default-image reconciliation so older images still fall back cleanly.

Add a daemon TAP pool to keep idle bridge-attached devices warm, expose stage timing in lifecycle logs, add a create/SSH benchmark script plus Make target, and teach verify.sh that tap-pool-* devices are reusable capacity rather than cleanup leaks.

Validated with go test ./..., make build, ./verify.sh, and make bench-create ARGS="--runs 2".

Add vsock-backed SSH session reminders
Remind users when a VM is still running after 	hanger vm ssh exits instead of silently dropping them back to the host shell.\n\nAttach a Firecracker vsock device to each VM, persist the host vsock path/CID,\nadd a new guest-side banger-vsock-pingd responder to the runtime bundle and both\nimage-build paths, and expose a vm.ping RPC that the CLI and TUI call after SSH\nreturns. Doctor and start/build preflight now validate the helper plus\n/dev/vhost-vsock so the feature fails early and clearly.\n\nValidated with go mod tidy, bash -n customize.sh, git diff --check, make build,\nand GOCACHE=/tmp/banger-gocache go test ./... outside the sandbox because the\ndaemon tests need real Unix/UDP sockets. Rebuild the image/rootfs used for new\nVMs so the guest ping service is present.

Refactor VM lifecycle around capabilities
Make host-integrated VM features fit a standard Go extension path instead of adding more one-off branches through vm.go. This is the enabling refactor for future work like shared mounts, not the /work feature itself.

Add a daemon capability pipeline plus a structured guest-config builder, then move the existing /root work-disk mount, built-in DNS, and NAT wiring onto those hooks. Generalize Firecracker drive config at the same time so later storage features can extend machine setup without another hardcoded path.

Add banger doctor on top of the shared readiness checks, update the docs to describe the new architecture, and cover the new seams with guest-config, capability, report, CLI, and full go test verification. Also verify make build and a real ./banger doctor run on the host.

Add tmux resurrect defaults to rebuilt images
New VMs should come up with tmux session persistence ready instead of requiring per-VM plugin setup, and rebuilt images should stop carrying stale Docker installer scraps.

Configure both image build paths to install TPM, tmux-resurrect, and tmux-continuum for root, manage a marked /root/.tmux.conf block with autosave enabled and restore left manual, and remove legacy get-docker helper files during provisioning.

Update the README and repo guidance to document the rebuilt-image behavior. Verified with bash -n customize.sh, GOCACHE=/tmp/banger-gocache go test ./internal/daemon -run TestBuildProvisionScriptInstallsDefaultTools, and GOCACHE=/tmp/banger-gocache make build.

Refresh docs for current VM workflows
Keep the user-facing docs aligned with the current Go control plane instead of the older one-VM-at-a-time and ambiguous rootfs rebuild flows.

Document concurrent multi-VM lifecycle and set commands, clarify that rebuilt images now include mise plus opencode, and spell out when make rootfs needs an explicit base image. Also update the repo guidelines so future changes keep those behaviors documented.

Move avoidable daemon shell-outs into Go
Reduce the control plane's dependency on helper scripts while keeping the hard Linux integration points in the approved shell-out layer.

Replace the bash-driven image build path with a native Go builder that clones and optionally resizes the rootfs, boots a temporary Firecracker VM, provisions the guest over SSH, installs packages and modules, and preserves the package-manifest sidecar.

Also replace a few small convenience shell-outs with Go helpers: read process stats from /proc, use os.Truncate for ext4 image growth, add file-clone and normalized-line helpers, drop the sh -c work-disk flattening path, and launch Firecracker via a direct sudo command.

Add tests for the new SSH/archive and system helpers, plus a policy test that keeps os/exec imports confined to cli/firecracker/system. Update the docs to describe customize.sh as a manual helper rather than the daemon's image-build backend.

Validated with go mod tidy, go test ./..., and make build.

Replace mapdns with daemon DNS
Serve daemon-managed .vm names directly from bangerd on 127.0.0.1:42069 instead of shelling out to mapdns. This keeps DNS state tied to VM lifecycle and lets the daemon rebuild records from running VMs after startup or reconcile.

Add a small in-process authoritative DNS server, register and remove records from the VM start/stop/delete paths, and show the listener in daemon status. Remove the mapdns config and preflight surface, stop helper-flow DNS publishing in customize.sh and interactive.sh, drop dns.sh from the runtime bundle, and update docs/tests for the new local-resolver integration model.

Validated with GOCACHE=/tmp/banger-gocache go test ./..., GOCACHE=/tmp/banger-gocache make build, and bash -n customize.sh interactive.sh.

Clarify local runtime bundle bootstrap
Stop presenting make runtime-bundle as a turnkey fresh-checkout bootstrap\nwhen the checked-in manifest is intentionally empty. The manifest comments,\nruntimebundle error messages, Make help, README, and AGENTS docs now all\ndescribe the same local-first flow: stage an archive, use a separate local\nmanifest copy with url/sha256, then bootstrap ./runtime from that manifest.\n\nKeep the existing package/fetch commands intact, and add a small runtimebundle\nregression test so the local-manifest guidance does not drift again.\n\nValidated with make help and GOCACHE=/tmp/banger-gocache go test\n./internal/runtimebundle.

Make runtime defaults portable
Stop assuming one workstation layout for runtime artifacts, mapdns, and host tooling. The daemon and shell helpers now use portable mapdns configuration, and runtime bundles can carry bundle.json metadata for their default kernel, initrd, modules, rootfs, and helper paths.

Load bundle metadata through config with a legacy layout fallback, thread mapdns_bin/mapdns_data_file through the Go and shell paths, and add command-scoped preflight checks for VM start, NAT, image build, work-disk resize, and SSH so missing tools or artifacts fail with actionable errors.

Update the runtime-bundle manifest, docs, and tests to match the new model. Verified with go test ./..., make build, and bash -n customize.sh interactive.sh dns.sh make-rootfs.sh verify.sh.

Switch to fetched runtime bundles
Stop treating Firecracker, kernels, modules, and guest images as tracked source files. Source checkouts now resolve runtime assets from ./runtime, while installed binaries keep using ../lib/banger.

Add a small runtimebundle helper plus runtime-bundle.toml so make can bootstrap, package, and install a runtime bundle with checksum validation. Update the shell helpers and daemon path hints to fail clearly when the bundle is missing instead of assuming repo-root artifacts.

This removes the tracked runtime blobs from HEAD in favor of an ignored local runtime/ tree. Verified with go test ./..., make build, bash -n on the shell helpers, make -n install, and a temporary package/fetch smoke test. The manifest URL/SHA still need a published bundle before fresh clones can bootstrap, and history rewrite remains a separate rollout step.
