Second milestone of the Windows parity work (DESIGN-WINDOWS.md §13).
WireGuard mesh client (signed, WSS-delivered):
- wireguard_apply / wireguard_remove commands: Ed25519-verified, gated on a new
wireguard capability. Linux applies via wg-quick up/down; Windows installs the
peer config as a WireGuardTunnel service via wireguard.exe
(/installtunnelservice, /uninstalltunnelservice)
- state polling in the home monitor drives the blue tray icon and auto-VPN:
connect when away from home + auto_vpn, disconnect on return (2m cooldown)
- tray VPN toggle and the auto-VPN checkbox are now live; the preference
persists to agent.yml (PersistAutoVPN)
IAM on Windows (iam_windows.go):
- allowed_login_groups -> net localgroup; ssh_keys -> per-profile
authorized_keys + %ProgramData%\ssh\administrators_authorized_keys;
revoke_users -> helper logs off all of the user's WTS sessions;
sudo_rules logged as no direct equivalent
Tray enrichment:
- Open Config (opens agent.yml), Clear enrollment (re-enroll) menu items
- set_auto_vpn persists; vpn_connect/vpn_disconnect/reinit/open_config commands
handled by the daemon (tray_server.go)
Packaging & release:
- installer/windows/installer.iss: fully-offline Inno Setup bundle (agent,
tray, helper, vendor-signed WireGuard MSI, OpenCredential CP, VC++ redist),
/SILENT /SERVER_URL /JOIN_KEY parameters, SYSTEM service + HKLM Run tray
autostart, Users-writable %ProgramData%\Theta42 for the IPC socket
- .github/workflows/build-windows.yml: build + test, pinned vendor downloads,
ISCC compile, Azure Trusted Signing (OIDC), SHA256SUMS, GH release attach,
optional SSO resource publish
- agent.yml.example documents auto_vpn, wireguard, service_name,
desktop_helper, public_ip_detect
Tests:
- wireguard_apply/remove dispatch (allowed + capability-denied), PersistAutoVPN,
ClearEnrollment; dispatch tests pin linuxPlatformOps with a temp WireGuard conf
- end-to-end verified against a local mock SSO on Windows: join-key enrollment
(token persisted, join key blanked), discovery/telemetry pushed, signed
arbitrary_bash verified + executed via powershell -EncodedCommand; tray IPC
socket binds %ProgramData%\Theta42; LDAP byte-pump binds 127.0.0.1:389;
helper update swap verified
Rebuilds all tracked dist binaries (v2.1.0).
First Windows parity milestone (DESIGN-WINDOWS.md §13 build order item 1).
- Add a PlatformOps abstraction so command dispatch is OS-neutral:
- linuxPlatformOps keeps today's systemctl/journalctl/bash behavior (deliberately
untagged so shared dispatch tests run on Windows CI)
- windowsPlatformOps maps reboot/shutdown to shutdown.exe, service control to
sc.exe (stop+start for restart), fetch_logs to Get-WinEvent, arbitrary_bash to
powershell -EncodedCommand (byte-exact under arbitrary quoting), and declines
configure_ldap (Windows logon goes through OpenCredential)
- Run theta-agent as a Windows service (x/sys/windows/svc): SYSTEM auto-start,
SCM stop/shutdown handling; CLI install-service/remove-service via svc/mgr
- Add theta-agent-helper (session-0 companion): lock/display_off/logout via
user32/wtsapi32, and staged self-update (wait for service stop, swap the
locked exe, sc start)
- Self-update becomes platform-aware: Linux renames over the running binary;
Windows stages .new and hands the swap to the helper (running exe is locked)
- Platform paths: agent.yml and tray.sock under %ProgramData%\Theta42 (the
service runs as SYSTEM while the tray runs as the user, so the per-user temp
dir no longer works for tray IPC); LDAP byte-pump falls back to TCP loopback
- config: service_name, desktop_helper, public_ip_detect (air-gap: skips
external public-IP lookups in telemetry + home monitor), wireguard block
- cli: platform-aware config path + self-update artifact name + service restart
- tests: dispatch tests pin linuxPlatformOps; 0600 mode assertions gated to
POSIX so the suite is green on Windows
Rebuilds all tracked dist binaries (v2.1.0).
See CHANGELOG.md for the full breakdown. Summary:
- ldap_tunnel.go: serves a local unix socket for SSSD/PAM and relays raw
bytes to the SSO over the existing WSS channel (ldap_tunnel messages);
the agent never parses LDAP (DESIGN.md §4). Adds safeWriter to
serialize WebSocket writes now that telemetry, heartbeat, the LDAP
tunnel, and command responses all share one connection.
- secrets.go: renders local templates ({{ bao "path#key" }} placeholders)
by fetching node-scoped values from the SSO and writing the target
atomically at 0600, on a signed render_secrets command (DESIGN.md §5).
demo/ has minimal bash + Node consumers of the rendered file.
- iam.go: applies signed node IAM pushes -- sudoers.d rules (visudo -c
validated), SSH AuthorizedKeysCommand keys, /etc/security/access.conf,
and revocation via sss_cache -E + pkill -u (DESIGN.md §6).
- Capability reporting: the agent's enabled capabilities ride along in
its discovery frame so the SSO can show them in the Directory.
- DESIGN.md: the v2 protocol design this implements.

Implements protocol v1.2.0.
verifySignature() returned true when no public_key was configured,
logging "skipping signature verification". The SSO installer never wrote
a public_key, so a default install executed reboot, service_restart,
configure_ldap, arbitrary_bash and update_binary UNVERIFIED from anything
that could reach its socket. An agent that cannot verify now refuses.
Canonicalization also disagreed with the server. Go's encoding/json
escapes <, > and & by default; JSON.stringify does not. Any payload
containing them hashed differently on each side and failed verification
-- for arbitrary_bash that is most real scripts (`>` redirection, `&&`).
Now uses json.Encoder with SetEscapeHTML(false), trailing newline
trimmed.
The SSO now rejects tokens it did not issue. Handles its close codes
(4001/4002/4003/4004) and backs off 5 minutes on an enrollment failure
instead of retrying every 5s forever. The connect log no longer prints
the URL, which carried ?token=.
install.sh gains --public-key and warns when none is configured.

The prebuilt theta-agent-linux-amd64 was built before the v1.3.0 heartbeat_ack
fix, so the installed agent still logged 'Unknown command type: heartbeat_ack'.
Rebuild it with the fix; add a test asserting heartbeat_ack is silently ignored
(no response, no command, no log).
