Problem

On Fedora, RHEL, Rocky and Alma, failproofai config fails at its last step: the daemon service never reaches a running state.

These distros run SELinux enforcing. The unit's ExecStart pointed at ~/.failproofai/bin/failproofaid-<version>, and SELinux labels files under /home user_home_t. The targeted policy gives systemd (init_t) no execute permission on that type, so the unit fails 203/EXEC Permission denied and waitForDaemonRunning() times out. Debian/Ubuntu/Mint and macOS don't enforce SELinux, which is why they work.

Verified against the shipped policies with sesearch / matchpathcon on Fedora 41 and Rocky 9:

Rule Fedora 41 Rocky 9
init_t execute user_home_t (old ExecStart) denied denied
/opt/failproofai/<user>/bin/* label bin_t bin_t
init_t + bin_t → unconfined_service_t yes yes
unconfined_service_t may run node from ~/.nvm yes yes
hook (unconfined_t) may connect to the daemon socket yes yes

Fix

On Linux, installDaemonService() now copies the binary as root (install → atomic mv) to /opt/failproofai/<user>/bin/failproofaid-<version>, runs restorecon on it when SELinux is enabled, and points ExecStart there.

  • Why /opt/.../bin: the policy's generic /opt/(.*/)?bin(/.*)? rule labels it bin_t. /usr/local/libexec is usr_t, and /usr is read-only on Silverblue/CoreOS. restorecon is needed because a new file inherits its directory's usr_t rather than the label the policy assigns to its path.
  • Per user, like the unit name, so one user's uninstall can't delete another's binary.
  • The ~/.failproofai/bin copy stays, because daemonVersionSkew() and refreshDaemonToCliVersion() read it.
  • Install prunes the /opt copies to the current version plus one. Uninstall removes the copy, and the manual-removal instructions now include it.
  • FAILPROOFAI_DAEMON_BINARY (an explicit binary or command) is started as given and not copied.
  • This applies to all Linux distros, not only SELinux ones. Existing installs move over on the next failproofai update or config, and keep running as they are until then.
  • macOS is unchanged.

Testing

  • Unit tests: target-path resolution (Linux, the /opt default, explicit binary, non-file, macOS) and the manual-removal text.
  • New root-only real-systemd test: installs a managed binary, asserts ExecStart is the root-owned 0755 copy, that the service is running, and that uninstall removes it.
  • Fedora 41, real systemd, as a non-root sudo user, real failproofaid + worker: install succeeds, the daemon runs from /opt/failproofai/alice/bin, and probeDaemonEndToEnd() and probeDaemonPolicyEvaluation() both return true. Reinstall pruned the old copies, and uninstall left nothing in /opt.
  • The root-only lifecycle suite (11 tests) passes on Fedora 41 and Ubuntu 24.04 containers with systemd.
  • tsc, lint, test:run (8751 passed) and test:e2e (364 passed) all pass locally.

Not covered: SELinux can't run inside Docker, so enforcing mode itself is verified from the policy, not a live run. Next is a beta install on a real Fedora machine.

Summary

Linux daemon staging is integrated across install, systemd, uninstall, tests, and release metadata. Three advisory correctness/operability issues remain: unsafe manual shell commands, staged-binary cleanup after failed installation, and a contradictory release-note version.

Changes

  • Stages managed Linux daemon binaries under /opt/failproofai//bin and updates systemd ExecStart.
  • Removes staged per-user binaries during daemon uninstall and documents manual removal.
  • Bumps release metadata to 1.0.13-beta.3.

Validation

  • Passed docker run --rm --network=none --cap-drop=ALL -v /review/input/workspace:/src:ro oven/bun:latest sh -lc 'bun build --no-bundle --target=node --outdir /tmp/out /src/src/hooks/daemon-service.ts /src/src/hooks/uninstall-cli.ts' — Both changed TypeScript modules transpiled successfully in an isolated container. (0s)
  • Skipped docker run --rm --cap-drop=ALL -v /review/input/workspace:/src:ro oven/bun:latest sh -lc 'cp -R /src/. /work/ && bun install --frozen-lockfile --ignore-scripts && bunx vitest run __tests__/hooks/daemon-service.test.ts __tests__/hooks/uninstall-cli.test.ts' — The isolated container could not resolve the public package manifest for vitest (DNSResolveFailed), so the targeted Vitest suite could not be installed or run; this is harness infrastructure, not attributable to the PR. (0s)

Findings

No blocking findings.

3 advisory findings
  • Medium/High Quote paths in manual Linux recovery commands — The no-elevation fallback joins shell commands returned by daemonInstallCommands(). Lines 937-939 interpolate dir, binaryPath, target, and systemBinaryRoot() without quoting; a valid FAILPROOFAI_HOME-derived binary path containing spaces is split by the shell, so install fails and the && chain never writes the unit. The newly added manual removal command also interpolates binDir unquoted in src/hooks/uninstall-cli.ts:426. (src/hooks/daemon-service.ts:937)
  • Low/High Roll back an unreferenced staged binary when install fails — stageSystemBinary() creates and moves the new /opt target before writePrivilegedFile(), daemon-reload, enable, and restart (lines 1021-1048). If any of those throws, the catch at lines 1064-1067 returns failure without removing the newly staged target; pruning only occurs after waitForDaemonRunning() succeeds. Failed upgrades across versions therefore accumulate root-owned unused binaries. (src/hooks/daemon-service.ts:1021)
  • Low/High Correct the npm version stated in the release note — CHANGELOG.md now labels the release 1.0.13-beta.3, and package.json, Cargo.toml, and hermes-plugin/plugin.yaml all declare 1.0.13-beta.3. The first feature entry nevertheless says the npm version “stays at 1.0.13-beta.0,” leaving the published release notes internally contradictory. (CHANGELOG.md:7)

Summary by CodeRabbit

  • New Features
    • Linux installations now run the daemon from a root-owned, system-managed location instead of the user’s home directory. SELinux labels are restored when applicable.
    • Updates and configuration changes migrate existing Linux installations. Older staged versions are pruned, retaining the current and most recent prior version.
  • Bug Fixes
    • Uninstall removes the staged Linux daemon files. Manual removal instructions include the same cleanup.

On Fedora, RHEL, Rocky and Alma, SELinux labels files under /home
user_home_t and gives systemd (init_t) no execute permission on that
type, so a unit whose ExecStart pointed at
~/.failproofai/bin/failproofaid-<version> failed 203/EXEC and
`failproofai config` aborted at its last step.

On Linux the install now copies the binary as root to
/opt/failproofai/<user>/bin/failproofaid-<version> (bin_t under the
policy's generic /opt/(.*/)?bin rule; restorecon re-applies it, since a
new file inherits its directory's usr_t) and points ExecStart there.
The daemon then runs as unconfined_service_t, which may run the worker's
node from ~/.nvm and accept hooks on the socket. The home copy stays for
the version checks; install prunes the /opt copy to current + one, and
uninstall removes it. macOS is unchanged.

Verified against the shipped policies (matchpathcon/sesearch on Fedora
41 and Rocky 9) and end to end on real systemd: the real daemon + worker
installed by a sudo user on Fedora 41 answers the hook and policy
probes; the root-only lifecycle suite passes on Fedora 41 and Ubuntu
24.04.

Walkthrough

Linux service installation now stages managed daemon binaries in a per-user system directory and uses the staged path for systemd. Installation attempts SELinux relabeling and prunes older copies. Uninstall removes the per-user directory, and manual removal instructions include the same cleanup. Release declarations change to version 1.0.13-beta.3.

Changes: Linux daemon binary lifecycle

Layer / File(s) Summary
Resolve and stage system binary
src/hooks/daemon-service.ts, __tests__/hooks/daemon-service.test.ts
Linux managed binaries resolve to versioned targets under /opt/failproofai by default. Installation stages the binary with elevated permissions and attempts SELinux relabeling when enabled. Explicit binary overrides and non-Linux platforms keep the supplied path.
Install and run from staged binary
src/hooks/daemon-service.ts, __tests__/hooks/daemon-service.test.ts, CLAUDE.md, CHANGELOG.md, Cargo.toml, hermes-plugin/plugin.yaml, package.json
Linux installation writes the staged path into the systemd unit and prunes older copies after the service runs. Manual-install instructions, project documentation, the changelog, and release declarations describe or reflect the staged path and release version.
Remove staged binary on uninstall
src/hooks/daemon-service.ts, src/hooks/uninstall-cli.ts, __tests__/hooks/uninstall-cli.test.ts
Linux uninstall removes the per-user system binary directory and attempts to remove the shared parent directory. Manual removal instructions and tests include the per-user directory cleanup.

Minor · Clean up the staged binary after unit creation fails. · daemon-service.ts:1816-1828

src/hooks/daemon-service.ts:1816-1828
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Clean up the staged binary after unit creation fails.

installDaemonService() stages the managed Linux binary before writing the unit. Its failure catch returns without removing the staged target. A unit-write failure can therefore leave a root-owned binary under /opt/failproofai/<user>/bin even though installation failed. Repeated failed versions can accumulate because pruning runs only after the service reaches a running state. Add rollback for this failed-install path while preserving any target still referenced by an existing unit.

The proposed cleanup at the no-unit uninstall return is not the reachable production correction: the uninstall CLI requires an existing unit, and the configure wizard requires a "running" service state.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Quote the managed binary path in the manual install recipe.

daemonInstallCommands() inserts binaryPath into sudo install -m 0755 ${binaryPath} ${target} without shell quoting. When canElevate() is false, installDaemonService() returns this command, joined with &&, as the manual install recipe. If the path contains a space, the shell splits it into separate words. install then receives the wrong source list, exits with an error, and the && chain stops before the systemd unit is written. This file already passes other command paths through shellQuote(), so this line should do the same.

Suggested fix

+          `sudo install -m 0755 ${shellQuote(binaryPath)} ${target}`,

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Route legacy Linux unit refreshes through binary staging.

When configuration finds a healthy daemon with a stale unit, ensureDaemonServiceCurrent() calls upgradedServiceDefinition(). That function preserves the existing home-directory ExecStart, while only the normal install path calls stageSystemBinary(). The next systemd start can therefore still use the SELinux-incompatible home path. Make the Linux upgrade-definition flow pass the staged path to systemdUnitContents() after elevation and preserve explicit command values.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clean up staged binaries when the unit is already absent.

survey() sets serviceInstalled from the unit file's existence. After manual unit removal, runUninstallCommand() clears daemonConfigured but skips the if (found.serviceInstalled) block, so uninstallDaemonService() is never called. Moving cleanup before its early return alone does not fix this supported uninstall path. Invoke cleanup for the configured-but-unit-missing state, and remove the staged directory in the missing-unit branch.

Superseded by #958, which merges this PR's code in full (c15b64e). The later 70d96ab only bumps the version to 1.0.13-beta.3, which #958 replaces with the stable 1.0.13. Checked file by file: every change here is in #958. The one addition is the quoting of the paths in the manual root recipes, raised in this PR's reviews.

…dora/RHEL, Antigravity path policies (#958)

* fix(daemon): run the systemd unit from /opt, not the home directory

On Fedora, RHEL, Rocky and Alma, SELinux labels files under /home
user_home_t and gives systemd (init_t) no execute permission on that
type, so a unit whose ExecStart pointed at
~/.failproofai/bin/failproofaid-<version> failed 203/EXEC and
`failproofai config` aborted at its last step.

On Linux the install now copies the binary as root to
/opt/failproofai/<user>/bin/failproofaid-<version> (bin_t under the
policy's generic /opt/(.*/)?bin rule; restorecon re-applies it, since a
new file inherits its directory's usr_t) and points ExecStart there.
The daemon then runs as unconfined_service_t, which may run the worker's
node from ~/.nvm and accept hooks on the socket. The home copy stays for
the version checks; install prunes the /opt copy to current + one, and
uninstall removes it. macOS is unchanged.

Verified against the shipped policies (matchpathcon/sesearch on Fedora
41 and Rocky 9) and end to end on real systemd: the real daemon + worker
installed by a sudo user on Fedora 41 answers the hook and policy
probes; the root-only lifecycle suite passes on Fedora 41 and Ubuntu
24.04.

* fix(openclaw): ask failproofaid over its socket instead of spawning the CLI

OpenClaw 2026.9.6 and later import plugins from a copy under
~/.openclaw/tmp/plugin-captures/ that holds only the plugin's own directory.
The plugin located the CLI relative to its own file (../dist/cli.mjs, then
bun ../bin/failproofai.mjs), so inside the copy it spawned a file that does
not exist and read the failure as an allow: every OpenClaw tool call ran
unchecked and no hook activity was recorded, while session telemetry kept
flowing. Verified live on 2026.10.5 by an A/B with the always-on guard.

The plugin now sends failproofaid the same `hook` request the CLI's --hook
path sends (raw event, cli "openclaw", payload as stdin, the gateway
profile's openclaw.json as agentSettingsPath) over the owner-only Unix
socket, as the Hermes plugin does, and reads the same flat verdict back, so
policies and verdict mapping are unchanged. Every module in openclaw-plugin/
imports only node built-ins and its siblings.

Like Hermes it is daemon-only: install requires a healthy daemon
(requiresHealthyDaemon), and when no verdict comes back before_tool_call and
before_agent_run fail closed with the reason logged through api.logger;
before_agent_finalize does not force a revise, which would only loop the turn.

* docs(changelog): link #957

* fix(openclaw): reject malformed daemon replies instead of reading them as allow

A hookResult frame missing stdout was read as an empty stdout, which is the
allow, and any string permission was accepted, so {"permission":"unknown"}
passed both gates (they block only on deny). Require the complete hookResult
the daemon always serializes (integer exitCode, string stdout and stderr),
accept only allow/deny/instruct, and type-check the optional reason,
policyName and policyNames; anything else is an invalid reply, so the tool
and prompt gates block. Adds regression tests for each shape, plus the two
reported cases end to end through the real daemon client. (SEC-001)

* fix(canary): start the daemon before a daemon-only CLI's install

OpenClaw now requires a healthy daemon to install, as Hermes already did, but
probe-cli.sh installed hooks before its first daemon_cycle and discarded the
installer's output. On the live daemon leg (the canary box's stable leg) the
install refused, the gateway started without the plugin, and both probes went
INCONCLUSIVE instead of testing enforcement — the same state Hermes was in.

- Live daemon leg: start a setup daemon before install_hooks/wire for the
  daemon-only CLIs (DAEMON_ONLY_CLIS="hermes openclaw"); each probe still
  cycles a fresh daemon into its own oracle dir.
- Keep the installer's refusal and print it with the verdicts instead of
  sending it to /dev/null.
- Any other leg (in-process beta, the dead-daemon leg): those CLIs cannot be
  hooked at all, and driving them unhooked would score the benign side effect
  as a silent-allow FAIL, so report INCONCLUSIVE with the reason and stop.

Tripwires: the shell list matches the integrations flagged
requiresHealthyDaemon, the setup daemon precedes install_hooks, the skip
happens before anything is installed or driven, and the refusal is reported.

* chore(release): 1.0.13-beta.1 for the OpenClaw socket fix

A branch beta under its own number rather than main's unpublished
1.0.13-beta.0, which main keeps for its own next cut: a dispatch publishes
whatever package.json carries, and a machine caches failproofaid per version,
so a shared number could also hand a later install the wrong daemon. Moves
package.json, the Cargo workspace version, Cargo.lock's workspace crates and
hermes-plugin/plugin.yaml together, as publish.yml's bump does, and gives the
release its own CHANGELOG section with this PR's entry.

* deps(sdk/python): bump nltk 3.10.3 -> 3.10.4 for GHSA-j456-xh4h-cpf2

Published 2026-10-28 (CVSS 8.6) against nltk 3.10.3, which sdk/python/uv.lock
pulls in through llama-index-core; the dev/test lockfile only, since the SDK
ships zero runtime dependencies. It turned OSV-Scanner red on every pull
request. Only the nltk entry moves: resolved with the uv CI uses (0.13.6, the
lockfile's revision 5) and checked with `uv lock --check`; osv-scanner with
the repo's config now reports no issues.

* fix(openclaw): limit the raw payload to 1 MiB, as the CLI does, not the envelope

The plugin capped the whole socket envelope at 1 MiB, but the envelope
carries the payload as an escaped JSON string plus routing fields, while the
CLI accepts up to 1 MiB of raw stdin (handler.ts, read-stdin.ts). A valid
payload near that limit was refused before connecting, and the gates then
blocked the call as a missing verdict. The payload is now bounded at the
CLI's 1 MiB and the envelope only by the daemon's 16 MiB frame limit; a
payload over 1 MiB is evaluated as empty, exactly as the CLI discards an
oversized stdin, and the plugin logs it rather than doing so silently.

* chore: bump to 1.0.13-beta.2 for the Fedora beta

1.0.13-beta.1 was published from another branch, and main's
1.0.13-beta.0 slot should stay free for main.

* fix(daemon): quote every path in the manual root recipes

When sudo is not available, `config` prints the commands to install the
service by hand and `uninstall` the commands to remove it. Since the /opt
staging change those recipes carried unquoted paths: a home directory with a
space split `sudo install -m 0755 <binary> <target>` into extra words, failing
the `&&`-joined recipe before the unit was written, and the removal recipe's
`sudo rm -rf <dir>` could be pointed at another path.

The existing POSIX `shellQuote()` moves to its own module so both files use
it (uninstall-cli's tests replace daemon-service wholesale, so it cannot be
imported from there), and every path in both recipes goes through it. A test
drives the real install path under a home with a space; it fails on the
unquoted recipe. The helper itself is checked against a real `sh`.

Raised by the Hermes and CodeRabbit reviews of #957.

* chore(release): 1.0.13

Stable release of OpenClaw enforcement on OpenClaw 2026.9.6 and later (#956,
shipped as 1.0.13-beta.1) and of daemon setup on Fedora/RHEL/Rocky/Alma
(#957). Moves package.json, the Cargo workspace version, Cargo.lock's
workspace crates and hermes-plugin/plugin.yaml to 1.0.13 together, and opens
the 1.0.13 CHANGELOG section that the release's announcement step reads:
#957's entry moves out of the never-published 1.0.13-beta.0 section into it,
beside the recipe-quoting fix; the 1.0.13-beta.* sections stay as they are.

* docs(changelog): reference #958 for the recipe quoting fix

* fix(hooks): enforce path policies on Antigravity's current file tools

agy delivers read_file {Path}, write_file {Path, Content} and edit_file
{Path, Target, Replacement}. None of those keys were mapped and write_file
was not a known tool, so path policies and the always-on guard over
failproofai's own state saw no path and allowed the call.

Live on agy 1.4.12 against the unfixed code, an agent printed .env,
overwrote and edited it, created id_rsa, and overwrote
.failproofai/policies-config.json. All five are refused with this change,
and normal reads, writes and edits inside the project still go through.
The older view_file and write_to_file spellings stay mapped.

Fixes #961

* deps: override minimatch to 11.0.3 for GHSA-g3hv-75wg-m249

The advisory, published 2026-10-30, covers every minimatch below 11.0.1, so
OSV-Scanner went red on every branch. Nothing here ships minimatch: it arrives
only through ESLint tooling in the root and sdk/typescript lockfiles.

The 3.x copies have no patched release, so the override crosses majors. Under
11.x require('minimatch') returns an object, so eslint-plugin-import, -jsx-a11y
and -react would throw if a rule reached their minimatch calls. The rules that
were checked are not enabled here and lint passes on the whole repo.

Pinned to 11.0.3 rather than 11.0.4, which was hours old.

* fix(uninstall): remove the staged daemon binary when the unit is already gone

uninstallDaemonService returned early with no unit, and the CLI only called it
when a unit existed. A failed install after staging, or a unit deleted by hand,
left the root-owned copy under /opt/failproofai/<user> while uninstall --purge
exited 0.

The copy is now checked independently of the unit, named in the plan, and
reported with a command to run as root if it survives. It is still removed only
after the unit: if the unit cannot be removed, the copy stays.

* fix(hooks): refuse an Antigravity file call with no recognizable path

A path key the maps do not know leaves file_path empty, so every path policy
has nothing to check and allows the call. That is how #961 stayed silent. A
Read, Write or Edit with no usable path is now denied whatever is enabled, with
a message saying to update failproofai. A session pause lifts it.

Registered from the handler rather than as a builtin: packs carry the policies,
and block-failproofai-commands is pinned never to route on Read. It registers
only for a call that lacks a path, so normal activity rows do not change. All
158 file tool calls in the local agy transcripts carry a recognized key.

The changelog also records the uninstall fix from the previous commit.

* chore(osv): drop the nltk ignore that no longer matches anything

nltk 3.10.4 is out of the advisory's range, so the scanner reports the entry as
unused. Leaving it would silently cover the advisory if the lockfile moved back.

* fix(hooks): keep the Antigravity path guard on under a pause when Cloud enforces

A session pause suspends local policy only, and Cloud policies keep running. With
the guard lifted, a pathless call would slip past a Cloud path policy that cannot
see the path either. A pause now lifts it only when no enforcing Cloud policy is
deployed. An observe-only Cloud policy decides nothing, so it does not count.

* test(daemon): keep the suites away from a machine's real daemon install

The real-systemd suite tore down with uninstall and then restored only the unit,
leaving it pointing at a deleted staged binary, and a daemon-configured machine
then denies every tool call. It now skips when a real unit is installed.

The uninstall-cli mock deleted its staged path on every test, including the
default /opt/failproofai/tester. Deletion is now off outside the suite that uses
a scratch directory.

* test(daemon): skip the real-systemd suite on any sign of a real daemon

A unit file is not the whole picture: systemd keeps a running service after its
file is deleted, and a failed install leaves a staged binary with no unit. The
suite now also skips for an active service or a staged directory.

uninstall-cli's staged path now lives in the per-test scratch directory, so a real
/opt/failproofai/tester cannot change a result.
