Perform an independent, read-only security review of every file under /home/byk/.local/share/opencode-v2-pilot/supervisor. Inspect exact current source, protocol, units, tests, docs, and pinned modules. Threat model same-UID malicious PTY descendants and untrusted model command/input/output. Focus on SO_PEERCRED/SO_PEERPIDFD authenticity and PID reuse, systemd MainPID/cgroup/invocation checks, inherited authenticated fds, SCM_RIGHTS and cwd TOCTOU, D-Bus transient unit injection, unit properties, Docker/D-Bus escape, cgroup containment, symlink/path attacks, environment/credential leaks, protocol desync/DoS, output/input memory bounds, session admission races, orphan cleanup, supervisor crashes/restarts, root-service attack surface, launcher privileges, and filesystem permissions. Do not edit files, install/start services, or run privileged operations. You may run unprivileged tests. Cite current file:line evidence and classify each finding PASS/CONCERN/MUST-FIX. End exactly MERGE or DO-NOT-MERGE.

I’ll inventory the exact supervisor tree, read every source, protocol, unit, test, doc, and pinned dependency file, then trace each trust boundary against the stated same-UID and untrusted-I/O threat model. I will keep the review read-only, run only safe unprivileged checks, and report findings with exact line evidence.

1: # PTY supervisor protocol
2: 
3: The protocol uses one Unix `SOCK_STREAM` connection for one PTY. Every frame has a 12-byte header:
4: 
5: - bytes 0–3: `OPTY`
6: - byte 4: version `1`
7: - byte 5: type
8: - bytes 6–7: zero
9: - bytes 8–11: unsigned big-endian payload length, at most 65536
10: 
11: The authenticated client sends one start frame (`1`) with exactly one `SCM_RIGHTS` directory descriptor. Its payload contains unsigned big-endian `st_dev` and `st_ino` values, an optional runtime in seconds, an argument count, and length-prefixed argument bytes. The supervisor compares the descriptor's metadata, requires a directory, and never resolves a client path.
12: 
13: After admission, the client sends input frames (`2`) of at most 32768 bytes. The supervisor sends output (`3`), exit (`4`), or error (`5`) frames. ...

The first source pass shows that the design does pin the peer with SO_PEERPIDFD, passes cwd by descriptor, fixes transient-unit names and arguments, and bounds individual frames. I am now checking the exact dependency implementations and effective unit/file controls because several guarantees depend on D-Bus FD marshalling, signal subscription behavior, systemd property semantics, and host permissions rather than this code alone.

Two merge blockers are now concrete: the manager queries only org.freedesktop.systemd1.Unit, but MainPID, SubState, Result, and ExecMain* belong to the service interface; and the transient unit runs untrusted commands as byk without home, process, network, device, or supplementary-group isolation. I am validating these against systemd 255 and checking shutdown/orphan races before assigning the final severity set.

Review Result I reviewed all 19 files under /home/byk/.local/share/opencode-v2-pilot/supervisor, both binaries, all pinned Go module declarations and relevant implementations, the unit files, protocol, tests, and acceptance document. I made no source or service changes and ran no privileged commands.

MUST-FIX

  1. MUST-FIX: systemd property queries use the wrong D-Bus interface, so authentication always fails and exit reporting cannot work.

ClientState calls GetUnitPropertiesContext and expects MainPID:

  • internal/supervisor/systemd.go:64-81
  • internal/supervisor/auth.go:18-27

The pinned go-systemd implementation requests only org.freedesktop.systemd1.Unit:

  • /home/byk/go/pkg/mod/github.com/coreos/go-systemd/v22@v22.5.0/dbus/methods.go:270-275

MainPID belongs to org.freedesktop.systemd1.Service, not Unit. An unprivileged host query confirmed systemd 255 rejects Unit.MainPID while returning Service.MainPID.

The same bug affects completion. Wait fetches Unit properties, then decodeUnitResult expects Result, ExecMainCode, and ExecMainStatus, which belong to the Service interface:

  • internal/supervisor/systemd.go:101-125
  • internal/supervisor/systemd.go:271-284

Current tests use synthetic maps and a fake manager, so they cannot detect this:

  • internal/supervisor/auth_test.go:9-27
  • internal/supervisor/systemd_test.go:51-58
  1. MUST-FIX: peer authentication does not prove one immutable systemd invocation and remains vulnerable to authenticated-FD delegation and PID-reuse races.

Positive checks exist, but they only compare a numeric PID, service state, and the service’s configured cgroup before and after one pidfd liveness probe:

  • internal/supervisor/auth.go:12-38
  • internal/supervisor/systemd.go:64-81

The code never checks:

  • The peer UID or GID from SO_PEERCRED.
  • The service InvocationID.
  • The actual peer process’s cgroup through the pinned pidfd. ...
