Widens #106272 to the one remaining sibling: `launchd_stop()` boots out with check=True and
already handles exit 3/113/125 (job unloaded) and 5/125 (domain unmanageable) by falling through
to the PID kill, yet inherited stderr — so `hermes gateway stop` against an unloaded job printed
"Boot-out failed: 3: No such process" next to "✓ Service stopped". Same `_CAPTURE_TEXT` kwargs as
the sibling calls; an unexpected exit still raises with `e.stderr` populated.
Replaces the contributor's two kwarg-assertion tests (`capture_output is True` on a mocked
`subprocess.run`) with two invariant tests that run a real fake `launchctl` on PATH and read fd 2
through `capfd`: restart-on-unloaded prints only its ↻/✓ lines and drives
kickstart→bootout→bootstrap→kickstart; stop-on-unloaded is silent, while a real bootout failure
(exit 1) still raises with the captured stderr. Both red on origin/main, green here.
Best-effort bootout calls (unloaded-job recovery, stale-EIO retry,
plist refresh, uninstall) and the handled kickstart -k in
launchd_restart inherited the terminal's stderr, so an expected
unloaded job printed raw launchctl errors around the CLI's own lines:
Could not find service "ai.hermes.gateway" in domain for user gui: 501
↻ launchd job was unloaded; reloading
Boot-out failed: 3: No such process
Capture them with _CAPTURE_TEXT instead. The kickstart error stays
available as e.stderr for the update_cmd failure diagnostic, and the
post-bootstrap kickstart intentionally stays loud (its failure feeds
the domain-unsupported fallback). Same precedent as the reload
helper, which already runs bootout with 2>/dev/null.
[salvage: picked hermes_cli/gateway.py only; the two capture_output kwarg-assertion tests are
replaced by fd-level invariant tests with a fake launchctl in the follow-up commit]
Defence at the exact boundary the incident crossed: systemd_uninstall() and
uninstall._remove_systemd_gateway() unlinked whatever get_systemd_unit_path()
returned. Before stop/disable/unlink, read the unit's own
Environment="HERMES_HOME=..." line (the parser status/refresh already use)
and, when it names a different home than this process, warn with both paths
and leave the unit alone. A unit without the line (hand-written) is still
removed as before.
With the previous commit a Docker/custom root (HERMES_HOME=/opt/data) gets a
hashed host-service suffix. Three callers used `_profile_suffix() or
"default"` as the PROFILE id, which is a different question: the s6
supervisor's slot for the root home is `gateway-default` regardless of where
the root lives, and the multiplexer's "am I a named profile" probe must not
treat a hash as a profile name. Route them through hermes_constants.
profile_name_for_home() (root -> "default", <root>/profiles/<name> -> name)
with the service suffix as the fallback for unknown layouts.
_profile_suffix() compared HERMES_HOME against get_default_hermes_root(),
which treats ANY home outside ~/.hermes (Docker /opt/data, a mktemp dir) as
"the root itself". Every such home therefore collapsed to the bare
`hermes-gateway` service name and the default profile's unit path
(~/.config/systemd/user/hermes-gateway.service); the documented
"else a short hash of the path" branch was unreachable.
A parity harness run with HERMES_HOME=$(mktemp -d) called
uninstall_gateway_service(), resolved to the production unit, ran
`systemctl --user stop/disable`, unlinked it and daemon-reloaded. With the
unit gone Restart= could not revive it: all cron jobs and every messaging
platform were down for 6.5 days.
Compare against the platform-native default home (~/.hermes) for the bare
name; keep the profile name for <root>/profiles/<name>; everything else
(temp dirs, Docker /opt/data) gets its sha256[:8] suffix as the docstring
always promised. The Docker image supervises with s6 (`gateway-<profile>`
slots), not systemd/launchd, so the bare host-service name was never load-
bearing there.
_user_systemd_socket_ready() accepts systemd/private alone, which is enough for
systemctl --user but not for the systemd-run --user that restart-safe workers
need; systemd_user_bus_env() requires the bus socket. Replace the uid threading
through five helpers with one _wait_for_target_user_bus(uid) that polls
/run/user/<uid>/bus, and move the post-enable wait + restart hint out of
_ensure_linger_enabled into _ensure_system_service_linger so the activity probe
runs only when linger was actually just enabled. Kanban applies the bus env
unconditionally like the cron sibling. Refs #104893.
run_gateway() adopts the user bus once at boot; the generated system unit had
no ordering against user@<uid>.service, so after a reboot the two race and
the adoption can miss until the next gateway restart. Emit After=/Wants=
user@<uid>.service for the unit's User= (uid now returned by
_system_service_identity, which already resolved the account). Existing
system units are flagged outdated once and refreshed on the next
install/restart. Refs #104893.
A system unit's `User=` has no login session on a headless host, so
user@<uid>.service never starts and `systemd-run --user --scope` — every
restart-safe cron/Kanban worker — has no bus to reach. `hermes gateway
install --system` runs as root and already knows the target user, so enable
linger for that user on fresh install, on an already-current unit, and on
repair.
- `get_systemd_linger_status()` / `_ensure_linger_enabled()` take the target
username; root is included (restart-safe workers cross `systemd-run --user`
regardless of who the gateway runs as).
- After `loginctl enable-linger` succeeds, wait for the TARGET uid's control
socket (`_wait_for_user_dbus_socket(uid=...)`) — logind starts the user
manager asynchronously and `--start-now` boots the gateway immediately; the
caller's own env (root's) says nothing about it and is never adopted.
- Messages and the manual-remediation hint are scope-aware (`sudo systemctl
restart`, not `systemctl --user`); when the repaired service is already
active, say that a restart is required — `systemctl start` on an active
unit is a no-op and the running gateway keeps its bus-less environment.
Refs #104893.
Drop the 3-line facade wrapper (hermes_cli/gateway.py is already 3x the facade
threshold) and call the existing _ensure_user_systemd_env() directly under
`is_linux() and INVOCATION_ID` — the same Linux gate the process_registry seam
uses, instead of os.name == "posix". The fail-closed test now targets
_ensure_user_systemd_env() itself. Hedge the scope-unavailable error text: the
probe also returns False when systemd-run is missing or times out, so the
D-Bus diagnosis is the usual cause, not the only one.
A system-level unit (/etc/systemd/system, User=<someone>) is exec'd with neither
XDG_RUNTIME_DIR nor DBUS_SESSION_BUS_ADDRESS, and a process environment is fixed
at exec time. 'systemd-run --user --scope' therefore fails for the whole lifetime
of that gateway even after the user manager is up and /run/user/<uid>/bus is
reachable. That is the seam every restart-safe worker crosses
(restart_safe_gateway_child_argv), and it fails closed by design — so on headless
systemd installs every agent-driven cron job and every Kanban dispatch died at
launch, ~26ms in, with nothing but 'error' on the job row.
_ensure_user_systemd_env() already derives both values from our own uid and adopts
them only when the runtime dir is really ours and the socket really exists; it was
just wired exclusively to the systemctl management paths, never to the gateway's
own boot. Call it from run_gateway() — the single in-process boot every entry point
goes through — so the adoption precedes every worker-environment snapshot (cron
builds its env after the scope check, Kanban before it, so fixing this at the
dispatch seam would only fix one of them).
The fail-closed posture is unchanged: with no user manager at all the probe still
reports unavailable and dispatch still refuses. That refusal now names the remedy
in the message the operator actually reads (it is stored as the cron execution's
error), instead of only the symptom.

Salvaged from #104272. Preserve restart and fatal-exit policy while classifying the planned restart code as success. Earlier analysis in #13604 by Justin Kausel.
Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
Re-applies the gateway compat removal byte-for-byte; see 92d0bd0d73 for the
full inventory (30 re-exports/aliases + 2 shim modules dropped, 3 shim-only
names re-removed, 24 callers + 34 test files repointed). No new changes.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
`hermes gateway status`, `hermes gateway list`, `hermes profile list/show`
and the dashboard profiles payload keyed liveness off the profile's own
gateway.pid / gateway_state.json, so a satellite profile served by the
default multiplexer (gateway.multiplex_profiles) showed "not running"
even though the multiplexer is its live inbound process.
Reuse the single lookup the start guard and cron liveness already share —
named_profile_served_by_running_multiplexer() — with an optional
profile_name so list surfaces can ask about any profile, and OR it into
gateway_running for named profiles. Default profile and unserved named
profiles are unchanged.
Salvage of #69118 rebased onto the shared helper (which post-dates it).

`asyncio.start_unix_server` does not exist on Windows (no AF_UNIX event-loop
support in asyncio), so arming the loop-tick witness in
`loop_heartbeat_forever` raised AttributeError on every native-Windows
gateway start. The broad except swallowed it and recorded
`loop_tick_socket=False`, so every stale-heartbeat probe classified the
gateway as UNKNOWN — never WEDGED, never ALIVE-with-stalled-write. The
two-witness interlock from a1c83ef9 (issue #90502 follow-up) has been
effectively disabled on Windows since it landed: a wedged native-Windows
gateway could never be detected, and an alive one could never be
distinguished from a stalled heartbeat write.
On non-POSIX platforms the witness now arms over a TCP loopback server on
127.0.0.1 (OS-assigned dynamic port) instead:
- same protocol — connect, read one byte "1"
- same semantics — pure in-memory, zero disk I/O, answered only while the
loop is dispatching, armed by the loop task itself (an awaited
`asyncio.start_server` is structurally loop-owned exactly like the Unix
variant, so a wedged loop cannot keep answering pings)
- the assigned port is published in the heartbeat payload as
`loop_tick_tcp_port`, and `probe_gateway_loop_liveness` prefers the TCP
witness when the producer published a port, falling back to the AF_UNIX
socket for POSIX/legacy producers
POSIX behavior is unchanged: the AF_UNIX arm (including the stale-node
sweep) stays gated behind `os.name == "posix"` so the missing attribute can
never raise on Windows again. Legacy heartbeats without `loop_tick_tcp_port`
keep the existing socket-node contract untouched.
Tested end-to-end on native Windows: witness arms, port is published,
`_probe_loop_tick_tcp` answers from an external thread while the loop
dispatches, and the existing loop-liveness suite passes unchanged (the
AF_UNIX structural test still passes — the Unix arm text is preserved
inside the POSIX branch).
Adds two tests pinning the new behavior: an E2E test that arms the TCP
witness and probes it (skipped on POSIX, where the Unix arm is the real
witness), and a structural test that the TCP arm stays awaited on the loop
task and the AF_UNIX arm stays POSIX-gated.
Fourth reproduction on #48820: the updater's post-update resume respawned
the gateway through _spawn_gateway_restart_watcher, the process died within
seconds (parent Job Object denying CREATE_BREAKAWAY_FROM_JOB kills the
child on job teardown), and "✓ Restarting Windows gateway profile(s)" was
printed anyway — 12.5h of silent platform downtime, with zero trace because
the watcher respawned with stdout/stderr=DEVNULL.
Three surgical changes:
1. Watcher respawn stdio → logs/gateway-stdio.log (hermes_cli/gateway.py).
The inlined watcher now routes the respawned gateway's stray
stdout/stderr to the same sidecar log gateway_windows._spawn_detached
uses (DEVNULL only as fallback), so a gateway killed moments after
respawn leaves a trace. Direct implementation of the 4th repro's
hardening suggestion (1).
2. Watcher respawn stamps _HERMES_GATEWAY_BREAKAWAY=1/0 exactly like the
canonical _spawn_detached, so the respawned gateway's exit-diag /
lifecycle records show whether it escaped the parent Job Object — a
job-teardown kill is no longer indistinguishable from any other silent
death.
3. Post-update resume verifies liveness before vouching
(hermes_cli/update_cmd.py). _resume_windows_gateways_after_update now
runs the same provisional-hit + 2s-confirmation liveness poll every
other spawn path uses (gateway_windows._wait_for_gateway_ready, widened
with all_profiles= for the fleet) before printing ✓, writes the #91675
start attestation for the verified PIDs, and fails the resume with a
"restart could not be verified" warning + recovery hint when no stable
gateway appears. Suggestion (2) of the 4th repro; closes the last
silent-success hole in the family (#84185 fixed the cold-start leg,
#91675 the direct-start leg; this is the relaunch leg).
Live proof on windows-latest (wine2e lane): real kill-on-close Job Objects
confirm breakaway children survive teardown and non-breakaway children die
(the exact #48820 mechanism); the real watcher respawn cycle leaves the
stdio trace + breakaway stamp; and the resume path refuses to print ✓ for
a dead relaunch.
Fixes the Bug-1 relaunch-trust leg of #48820.
/simplify-code quality+efficiency reviewers (converged, verified): on
the standard 'hermes gateway run' path the argv fast-path arms BEFORE
run_gateway's config bridge executes, and arm_startup_watchdog() is
idempotent — so gateway.startup_watchdog: false and
startup_watchdog_timeout_seconds were dead knobs (env bridged, live
handle untouched). run_gateway now applies the config to the live
handle: disarm on disable; disarm+re-arm on a bridged config timeout so
the fresh handle covers the remaining pre-loop startup with the
configured deadline. config_defaults comment updated to match reality.
E2E (real module, fast-path armed first): disable path disarms the live
handle; timeout path re-arms a fresh handle at 123s.
Review follow-ups on the salvaged #89750:
- gateway.startup_watchdog / gateway.startup_watchdog_timeout_seconds in
config_defaults, bridged to the internal HERMES_STARTUP_WATCHDOG env
vars in run_gateway() (the argv fast-path arms before config can load,
so env remains the mechanism; config.yaml is the user-facing surface
per policy — explicit env values still win as operator override).
- hermes_cli/main.py argv sniff now requires the ADJACENT token pair
'gateway run' instead of independent membership, so unrelated commands
mentioning both words can't arm a 300s hard-exit timer; profile-flagged
invocations (-p work gateway run) still arm.
