Hermes: update migrates to a linked plugin; no bundled Jev checks; shadow mode is observe - #868
Merged

Conversation
…ying it Hermes has no configurable plugin search path, so the plugin was copied into <profile>/plugins/failproofai and went stale on every npm upgrade until someone reran setup. Install now symlinks that path to the package's own hermes-plugin/ (the OpenClaw plugins.load.paths model), so an upgrade applies with no reinstall. Hermes' scan_directory uses Path.is_dir(), which follows the link, and skips a dangling one silently. Ownership stays strict: only a marked copy (1.0.6-1.0.8 installs) or a link into a FailproofAI hermes-plugin/ (checked by basename and manifest name) is ever replaced or removed; an unmarked dir, a file, or a link anywhere else is refused. A copy is migrated to a link; where a link cannot be created the install falls back to the marked copy. Uninstall unlinks, never touching the package directory. Health gains pluginMode and cronUnchecked: a profile still on legacy config.yaml shell hooks is reported UNHEALTHY with "Hermes cron jobs are not checked", since cron fires build their own hook scope that config shell hooks never join. Adds migrateHermesProfiles(), the per-profile state machine `update` uses. The Hermes tests now copy hermes-plugin/ into a temp package root (a test editing files through the installed plugin would otherwise edit the repo's plugin via the link) and refuse to run when HOME overrides are not honoured by os.homedir() (Bun caches it), which would point them at a real ~/.hermes.

…en it cannot `update` never looked at Hermes, so a machine that installed Hermes enforcement with <=1.0.5 kept its config.yaml shell hooks through every npm upgrade - and those hooks are never run for Hermes cron jobs, so scheduled jobs went unchecked while `update` reported success. After the daemon step, every Hermes profile that already uses FailproofAI (legacy shell hooks, a copied plugin, or a link) is brought to the linked plugin: plugin first, then plugins.enabled, then the legacy hooks are removed. Profiles with no FailproofAI integration are left alone, and a config.yaml that does not parse is never rewritten. The running daemon is probed for policyEvaluation (once, only when a profile needs changing); when it cannot serve the plugin - e.g. a sudo system daemon update could not replace - nothing is changed, the shell hooks stay, and update exits 1 telling the user to run `failproofai config`. A per-profile report is printed. Exit status is now non-zero when the daemon swap failed, a layout migration failed, or any Hermes profile could not be brought current.

Harness and CLI reference, the plugin README, CLAUDE.md and the 1.0.9-beta.0 changelog now describe the linked install, `update` migrating Hermes profiles (and exiting non-zero when it cannot), and why legacy shell hooks leave Hermes cron jobs unchecked. English pages only; translations not updated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Jev's log-only mode is being renamed from "shadow" to "observe". Hook rows written by an older worker or daemon still say "shadow", and the activity store is never rewritten, so the collector accepts both and normalizes "shadow" to "observe" before emitting jev_mode — the Cloud sees a single spelling per mode. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Jev's log-only mode (asked and logged, regex decides) is now "observe",
the word already used for a policy rollout that is evaluated but not
enforced. Every writer emits "observe": jev.json (CLI setup, config
--token's initial Cloud file, the dashboard actions), hook-activity rows'
jevMode, verdicts.jsonl's applied, and the jev status stats
(observeClearsByPolicy, modes.observe). CLI help, status text, dashboard
panel and the activity pill ("jev observe") say observe.
"shadow" stays a read alias wherever a mode is parsed: normalizeJevMode in
jev-config (so an existing jev.json, a Cloud-written file, --mode shadow,
and the dashboard server actions all accept it), sanitizeJevActivity for
rows an older worker wrote, and the stats renderers for the pre-rename
keys. --mode shadow saves "observe" and prints a one-line note; any save
rewrites an older file's "shadow" as "observe".
Internal names follow: JevMode, ObserveVerdict/observeVerdict,
CLOUD_JEV_INITIAL_MODE. The collector's golden fixtures are regenerated
from the store.

Rename shadow mode to observe across the Jev docs (setup, providers, Cloud route, CLI reference, local dashboard), noting that "shadow" is still accepted and saved as observe. CHANGELOG entry for the rename and its compatibility. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The Cloud's enforcement summary reports jev.machines.observe (and keeps jev.machines.shadow as a deprecated duplicate; older servers send only shadow). `fp guardrails summary` reads observe, falls back to shadow, never sums them, and prints "observe".

The sixteen semantic checks were compiled into the npm package and used whenever no installed pack declared any, so configuring Jev (BYOK, or `config --token` with a Cloud machine key) started asking them without anyone opting in. They now reach a machine only through `failproofai policies add FailproofAI/jev-policies`. - semantic/policies.ts keeps the probes and path/branch helpers; the sixteen definitions move to a test fixture (__tests__/fixtures/jev-policies.ts). - semanticPoliciesFromPacks / resolveSemanticPolicies return an empty set with no declaring pack, when every entry is unusable, and when the manifest is unreadable. Third-party checks no longer join a built-in set. - Reviewer names come only from installed packs (effectiveReviewerNames / reviewerNamesFor -> NO_REVIEWERS when none); resolvePolicyAuthority and withMergedAuthority default to no reviewers, and with none a reviewable declaration resolves hard silently (a contest is still reported). SEMANTIC_REVIEWER_NAMES stays as the reserved names and the build-time vocabulary for the core pack and `publish`. - handler: no Jev review and no intent capture unless an installed pack gives Jev checks (jevChecksInstalled), so a machine without one never reaches the network for Jev. - jev status / dashboard: coverage carries jevChecks; with none, the problem line says Jev has no checks installed and names the command. `config --token` says the same when it turns Cloud Jev on.

FailproofAI/jev-policies carries no regex policies, but hasInstalledPacks() counted it: installing it switched off a legacy machine's enabledPolicies, and a later `policies add <name>` tried to enable the name on it instead of fetching FailproofAI/policies. Both now ask hasInstalledRegexPacks(). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Jev's modes are off | observe | enforce, nothing else. Removes every read alias for the old name: LEGACY_OBSERVE_MODE and normalizeJevMode (now parseJevMode, the three modes only), the `--mode shadow` note in `jev setup`, the dashboard actions' alias, sanitizeJevActivity's row rewrite, the stats renderers' shadowClearsByPolicy / modes.shadow fallbacks, the collector's `shadow` jevMode arm, and fp's jev.machines.shadow fallback — plus the tests, docs and CHANGELOG text that described them. A jev.json with mode "shadow" is now an invalid mode like any other: refused, Jev off. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Hermes found blocking issues that should be addressed.
Review coverage was incomplete, but the concrete blocking findings below are sufficient to request changes.
High: Bundled CLI resolves the Hermes plugin outside its npm package
- Rule:
COR-001 - Location:
src/hooks/integrations.ts:1425 - Evidence:
getHermesPluginSourcePath()resolves three parents fromfileURLToPath(import.meta.url)atsrc/hooks/integrations.ts:1425. That works fromsrc/hooks/integrations.ts, but the shipped CLI isdist/cli.mjs; three parents from that path point to the package's parent (.../node_modules/hermes-plugin), not.../failproofai/hermes-plugin. The new update migration callsinstallHermesPlugin, which then rejects the missing plugin asset and leaves legacy shell hooks in place, so Hermes cron jobs remain unchecked. - Required change: Resolve the package root in a way that supports the bundled
dist/cli.mjslayout (or inject it at build time), and add an npm-pack integration test withoutFAILPROOFAI_PACKAGE_ROOTthat verifiesupdatelinks to the packagedhermes-pluginassets.
2 advisory findings
- Medium/High Existing shadow activity is misclassified as enforced activity —
sanitizeJevActivitynow drops every mode other thanobserveorenforceatsrc/hooks/jev-activity.ts:239. It is also used when reading existing rows for the dashboard and Jev stats. Consequently, a persisted pre-upgrade{jevMode:"shadow", jevCleared:[...]}row loses its mode;computeJevStatsthen places its clears inclearsByPolicyrather thanobserveClearsByPolicy. The collector similarly discardsshadowatcrates/fpai-collect/src/sources/hooks/transform.rs:414. (src/hooks/jev-activity.ts:239) - Medium/High Jev-only packs make status hide still-enforced legacy policies — The runtime correctly uses
hasInstalledRegexPacks()before retiring theenabledPoliciesmigration shim (src/hooks/handler.ts:573). In contrast,surveyReviewableCoverage()still useshasInstalledPacks()atsrc/hooks/policy-reviewability.ts:170, then suppresses all legacy enabled policies at line 197. A machine with onlyFailproofAI/jev-policiestherefore continues enforcing its legacy builtins butjev statusand the dashboard report coverage as though those policies were absent.

… plugin path - policy-reviewability: the coverage survey retires the enabledPolicies shim only when a pack with regex policies is installed, as handler.ts does; a Jev-only pack no longer makes jev status and the dashboard under-count. - jev-activity: a row whose Jev mode is unknown (e.g. a pre-rename "shadow") drops its clears instead of having them counted as enforce-mode clears. - integrations: without FAILPROOFAI_PACKAGE_ROOT, find hermes-plugin/ by walking up to its plugin.yaml (three fixed parents overshoot from dist/); a failed junction-over-junction rename on Windows falls back to the move-aside swap.

Hermes found blocking issues that should be addressed.
High: Hermes migration can irrecoverably corrupt config.yaml
- Rule:
DATA-001 - Location:
src/hooks/integrations.ts:91 - Evidence: The new update migration removes legacy hooks in memory and then calls
writeYamlDoc()atsrc/hooks/integrations.ts:1843-1845.writeYamlDoc()uses directwriteFileSync()at line 93, which truncates the live config rather than atomically replacing it. An interruption after truncation can leave a partial or invalid config; a later update then detects parse errors and refuses to repair it, leaving the user to reconstruct their Hermes configuration and potentially without enforcement. - Required change: Write the rendered YAML to a uniquely named temporary file in the config directory, fsync it, and atomically rename it into place. Preserve a recoverable prior copy or restore it on failure, and add an interruption/retry test.

…t parse Addresses DATA-001 on #868. Every integration wrote the user's agent config with an in-place writeFileSync, so an interruption left a truncated config (for Hermes: a gateway that will not start), and readYamlDoc read an existing file that does not parse as an EMPTY document, so the next install would have replaced every other setting in it. - safe-config-write.ts: temp file in the same directory, fsync, copy the previous version to <name>.failproofai-backup, atomic rename, fsync the directory. Keeps permission bits (Hermes config.yaml is 0600) and writes through a symlinked config. Any failure before the rename leaves the live file untouched and removes the temp file. - writeJsonFile / writeYamlDoc / the OpenCode shim use it. - readJsonFile / readYamlDoc throw UnreadableAgentConfigError for a file that exists but cannot be read or parsed; status surfaces use a non-throwing inspect and report "does not parse" for Hermes. - update's Hermes migration reports a broken config.yaml it manages as failed (left untouched) and leaves one it never managed alone. - collector: a row whose Jev mode is unknown ships no clears (advisory). Tests: interruption, retry after a stale temp file, backup, permissions, symlink, refusal for YAML and JSON, and the migration cases. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Hermes found blocking issues that should be addressed.
High: Disabled Hermes plugins are reported healthy and skipped by update
- Rule:
SEC-001 - Location:
src/hooks/integrations.ts:1772 - Evidence:
hermesConfigStatesetspluginEnabledsolely fromplugins.enabledat src/hooks/integrations.ts:1772, although the migration writer explicitly removesfailproofaifromplugins.disabledbefore enabling it. That state is used by the already-current branch at line 1874 and health calculation at lines 1969-1980. A container probe created a current plugin with bothenabled: [failproofai]anddisabled: [failproofai];hermesProfileHealth()returnedhealthy: true, so update would report it current without repairing the disabling entry. - Required change: Treat
plugins.disabledcontainingfailproofaias not enabled in the shared config-state helper, so health, installed detection, and the migration current check all require that it is enabled and not disabled. Add a regression test covering a linked plugin with both lists populated.
1 advisory finding
- High/High A same-named operator plugin link is claimed as FailproofAI-managed —
isFailproofaiHermesPluginSourceaccepts any readable target whose basename ishermes-pluginand whoseplugin.yamlcontainsname: failproofai(src/hooks/integrations.ts:1526-1531).installHermesPluginthen treats that link as owned and replaces it. A container probe created/tmp/operator/hermes-pluginwith that manifest and the required files, linked a Hermes profile'splugins/failproofaito it, andinstallHermesPluginreturnedlinkedinstead of refusing the foreign link. (src/hooks/integrations.ts:1526)
…001) Hermes gates plugins.disabled before plugins.enabled, so a profile listing failproofai in both never loads it. hermesConfigState read only plugins.enabled, so health reported it healthy, installed detection said installed, and update skipped it as "already current" without removing the disabling entry. The shared helper now requires listed AND not disabled; status names the disabled state; update treats either listing as ours and repairs it (enableHermesPluginInDoc already drops the disabled entry). Regression test: a linked plugin with both lists populated is unhealthy, not installed, not current, and healthy after update. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Hermes found blocking issues that should be addressed.
High: A same-named foreign Hermes plugin link is treated as managed
- Rule:
COR-001 - Location:
src/hooks/integrations.ts:1526 - Evidence:
isFailproofaiHermesPluginSource()atsrc/hooks/integrations.ts:1526accepts any readable target namedhermes-pluginwhoseplugin.yamlsaysname: failproofai.hermesPluginState()therefore classifies an operator-owned link aslink, andinstallHermesPlugin()replaces every non-current link at lines 1631-1705. A foreign plugin can meet those two public naming conditions, contrary to the migration’s stated rule that foreign same-name plugins are never touched. - Required change: Persist an ownership marker outside the linked directory when creating a managed link and replace only marked links. Treat unmarked links as foreign, including links with a matching directory and manifest name; retain any required stale-link migration through explicit, verifiable provenance.
3 advisory findings
- High/High Backup creation follows an attacker-controlled symlink —
writeConfigFileAtomic()callscopyFileSync(target,${target}.failproofai-backup)atsrc/hooks/safe-config-write.ts:92without inspecting the existing backup path. Project-scoped Claude settings are written under<cwd>/.claude/settings.json, so a repository can pre-create.claude/settings.json.failproofai-backupas a symlink to any file writable by the developer. A container probe created that link and showed a normal config write changed the linked victim fromunchangedto the prior config contents (old). (src/hooks/safe-config-write.ts:92) - Medium/High A dangling config symlink is replaced instead of written through —
resolveWriteTarget()returns the original symlink pathname whenrealpathSync()fails at lines 58-64. For a dangling config symlink, the later rename at line 94 replaces that link with a regular file. A container probe confirmedlinkPreserved: falseand that the intended dotfiles target remained absent after a write. (src/hooks/safe-config-write.ts:60) - Medium/High A transient Hermes config read error aborts migration of remaining profiles — After
hermesConfigState()has already parsed the profile,migrateHermesProfiles()performs another unguardedreadFileSync()and YAML parse at lines 1905-1916. If the config is removed or becomes unreadable betweenexistsSync()andreadFileSync(), the exception escapes the loop rather than producing a failed result for that profile, so later profiles are not processed and the promised per-profile report is lost. (src/hooks/integrations.ts:1905)
Round 4 of 5. If the next review still finds something blocking, I will summarize what is left, withdraw this change request, and stop reviewing this pull request until someone asks me to start again.
Still open:
- F8 Backup creation follows an attacker-controlled symlink (
src/hooks/safe-config-write.ts) — noticed at round 4, on code that had not changed since the round before, so it never blocked - F9 A same-named foreign Hermes plugin link is treated as managed (
src/hooks/integrations.ts) — open since round 4 - F10 A dangling config symlink is replaced instead of written through (
src/hooks/safe-config-write.ts) — noticed at round 4, on code that had not changed since the round before, so it never blocked - F11 A transient Hermes config read error aborts migration of remaining profiles (
src/hooks/integrations.ts) — open since round 4
If one of these is not worth fixing, @hermes-exosphere dismiss <id> [reason] waives it for the rest of this pull request and gives the review another round.
refreshDaemonToCliVersion reinstalled the service on every `update`. The install is idempotent but needs root, so after the daemon was brought current, an interactive update asked for a sudo password for nothing and a non-interactive one failed "root privileges are required" and exited 1 on a healthy machine. Now, when the service is running and VERSION.daemon equals this CLI's version with that binary on disk, it reports the daemon current and asks nothing. Verified live: exit 0, Hermes profiles "already current". Also bumps to 1.0.9-beta.3 (1.0.9-beta.2 is published from 6e4e2d5). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

I have spent 5 rounds of review on this pull request and I am still finding things to block on. At that point I am no longer the useful reviewer here, so I am standing down and leaving the decision to a person. I have withdrawn my change request, so I am no longer blocking this pull request. I have also stopped reviewing new commits on it. What I last reviewed: Still open:
None of this is a judgement that the findings above are wrong. It is a judgement that another round of me is not what will settle them. |

…, plugin ownership, per-profile isolation) - F8 safe-config-write: the backup is copied to an exclusively created temp file and renamed over <name>.failproofai-backup, so a symlink planted there is replaced, never followed (probe: victim file stays unchanged). - F10: a config that is a dangling symlink is refused (DanglingConfigSymlinkError) instead of being replaced by a regular file. New `symlinks: "replace"` mode for files failproofai generates without reading (OpenCode shim, link record): a planted link is swapped out, its target never written. - F9: a Hermes plugin link is failproofai's only when it matches the ownership record written beside it (plugins/.failproofai-link) or points into an npm `failproofai` package (verified via its package.json) — the 1.0.9-beta links are adopted and recorded. A look-alike `hermes-plugin` with a `name: failproofai` manifest is foreign: never replaced, and status says so. - F11: each profile is migrated in its own try/catch and the redundant second read/parse of config.yaml is removed, so one profile's error is its failed line, not the end of the report. - update labels a re-enabled plugin "plugin re-enabled (was listed in plugins.disabled)". Verified on a real machine: beta links adopted + recorded, configs byte-identical, look-alike plugin untouched, planted backup link replaced with victim intact, live Hermes tool calls checked in Cloud.

Renames the unreleased 1.0.9-beta.3 heading to `## 1.0.9 — 2026-09-29` and gives it a lead, as #840 did for 1.0.7: release-announcement.mjs merges `## 1.0.9` with the published `## 1.0.9-beta.*` sections, so those stay as they are. The lead puts the one action existing Jev users must take (shadow is refused; re-run `jev setup`) before Discord's truncation point. Adds the 13 dependency bumps merged from main (#853–#865), which had no entry. Version files stay at 1.0.9-beta.3, as v1.0.7 and v1.0.8 were tagged: the release tag sets the npm version and the daemon check matches the base.

Why
A customer's Hermes agents lost all policy checks after upgrading with
npm i -g failproofai && failproofai update. Reproduced on Hermes 0.21.3: the legacy Hermes integration (shell hooks inconfig.yaml, written by ≤1.0.5) is never run for cron jobs inside the Hermes gateway — each cron fire builds its own hook scope that only discovered plugins join. The native plugin (1.0.6+) is checked in cron, butupdatenever touched Hermes, so upgraded machines stayed on shell hooks until someone ranfailproofai config. Nearly all of that customer's Hermes traffic is cron.This PR also carries two product decisions for 1.0.8: the package ships no policies, Jev checks included, and Jev's log-only mode is called observe.
What changes

Profiles without FailproofAI are left alone; a foreign plugin with the same name is never touched.policyEvaluation), the shell hooks are kept andupdateexits 1 pointing atfailproofai config. It also exits 1 when the daemon swap or a layout migration failed.failproofai config --statusreports a profile still on shell hooks as unhealthy: "Hermes cron jobs are not checked".2.
