Implement a minimal secure Go PTY supervisor and fixed launcher under /home/byk/.local/share/opencode-v2-pilot/supervisor only. Do not edit repository files, current plugin, system units outside that directory, or start/install services. Use tabs/go fmt. You may fetch pinned Go modules. Requirements from independent design: root-owned Unix socket server intended at /run/opencode-pty/supervisor.sock; authenticate each connection with SO_PEERCRED plus SO_PEERPIDFD if available and exact equality to systemd's current MainPID for fixed opencode-v2.service, exact expected cgroup, ActiveState active; fail closed without pidfd. One SOCK_STREAM connection per PTY with bounded binary framing. Secure SCM_RIGHTS transfer of approved cwd descriptor from authenticated client, compare st_dev/st_ino metadata, and a fixed launcher that receives cwd fd, fchdir, clearenv/set fixed env, then exec /usr/bin/script with strictly encoded argv. Use maintained Go D-Bus/systemd library and direct StartTransientUnit if its API can pass stdio fds and properties; monitor structured Result/ExecMainCode/ExecMainStatus and unit removal. Generated random 128-bit fixed-grammar unit names only. Every unit User/Group=byk, NoNewPrivileges, UMask, KillMode=control-group, TERM/KILL/TimeoutStopSec, RuntimeMaxSec optional, OOMPolicy kill, Delegate no, BindsTo/After supervisor, mask Docker and system/user DBus sockets, use dedicated opencode-pty.slice; never inherit environment or accept systemd property names/unit names/paths from client. Bound sessions/frames/input/output/backpressure. On client disconnect/protocol error/supervisor shutdown stop unit by name and await inactivity. Startup orphan cleanup by strict unit grammar and BindsTo verification. Include service/slice files in this isolated directory and unit/protocol tests that don't require root. ...

Cloning into '/tmp/opencode/systemd-v255'...
Note: switching to 'db11bab38ccf1ed257f310d29070843d4c58ea01'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

I’ll first prove the pinned systemd client can send Unix file descriptors through StartTransientUnit. The host runs systemd 255, whose transient service API accepts StandardInputFileDescriptor, StandardOutputFileDescriptor, and StandardErrorFileDescriptor as D-Bus h values. This lets the supervisor pass one duplex I/O socket and the approved cwd descriptor without inventing an FD transport.

Implemented

  • SO_PEERCRED and mandatory SO_PEERPIDFD authentication.
  • Exact opencode-v2.service MainPID, active state, and cgroup checks.
  • Bounded binary framing, session count, socket buffers, arguments, and I/O frames.
  • Secure SCM_RIGHTS cwd transfer with descriptor metadata verification.
  • Random 128-bit, fixed-grammar transient unit names.
  • Direct StartTransientUnitContext use with D-Bus Unix FD properties.
  • Fixed transient-unit properties, isolation, lifecycle monitoring, cleanup, and structured exit results.
  • Fixed launcher environment, cwd descriptor handling, canonical base64 argument grammar, shell quoting, and /usr/bin/script execution.
  • Strict orphan cleanup using unit-name and BindsTo verification.
  • Root and slice unit definitions.
  • Unit, protocol, authentication, descriptor-transfer, fragmentation, and launcher tests.

The service references root-controlled binaries under /usr/local/libexec. It never runs a root service from the user-writable source directory.

Validation

Passed:

  • gofmt
  • go test ./...
  • go test -race ./...
  • go vet ./...
  • Both production builds
  • Exact built-launcher cwd/exec smoke test
