- Deny-by-default filesystem isolation for Linux (Landlock) and macOS (Seatbelt)
- Prevent learning mode from collapsing read paths to $HOME
- Add Linux deny-by-default lessons to experience docs
Show installed dependencies, security features, and transparent proxy
availability when running --version. Detect AppArmor
unprivileged_userns restriction on Ubuntu 24.04+ and suggest the fix.
Document the RTM_NEWADDR issue in experience.md.
Learning mode (--learning) traces filesystem access with strace and
generates minimal sandbox config templates. A background monitor kills
strace when the main command exits so long-lived child processes (LSP
servers, file watchers) don't cause hangs.
Other changes:
- Add 'greywall templates list/show' subcommand
- Add --template flag to load specific learned templates
- Fix DNS relay: use TCP DNS (options use-vc) instead of broken UDP
relay through tun2socks
- Filter O_DIRECTORY opens from learned read paths
- Add docs/experience.md with development notes
Rebrand the project from Fence to Greywall, the sandboxing layer of the
GreyHaven platform. This updates:
- Go module path to gitea.app.monadical.io/monadical/greywall
- Binary name, CLI help text, and all usage examples
- Config paths (~/.config/greywall/greywall.json), env vars (GREYWALL_*)
- Log prefixes ([greywall:*]), temp file prefixes (greywall-*)
- All documentation, scripts, CI workflows, and example files
- README rewritten with GreyHaven branding and Fence attribution
Directory/file renames: cmd/fence → cmd/greywall, pkg/fence → pkg/greywall,
docs/why-fence.md → docs/why-greywall.md, example JSON files, and banner.
