`block-self-pause` and `block-failproofai-commands` were two halves of one
guard, and they disagreed with each other.
`block-self-pause` had the hardened matcher — segments split on shell
operators, runner prefixes and their flags walked off, the binary resolved by
basename, the shell-unescaped form re-checked — but only ever looked for
`config --pause`. `block-failproofai-commands` had the whole surface, any CLI
invocation plus package-manager uninstall, on a regex a single prefix defeated:
`sudo failproofai config --pause`, `npx failproofai policies --uninstall`,
`env X=1 failproofai …`, `/usr/local/bin/failproofai …` and
`timeout 30 failproofai …` were all ALLOWED by a default-on self-protection
policy. The merged policy is the hardened matcher over the broad surface, and
it keeps `PermissionRequest` from the merged-in half — a real enforcement point
on Copilot and Devin that the survivor never subscribed to.
Where the two contradicted each other, the merge keeps what machines actually
did. `block-self-pause` deliberately allowed `config --resume`, `config
--status` and `policies --install`; both policies were default-on and the
sibling denied all three first, so that allow never ran anywhere.
It is now `alwaysOn`, a new flag `registerBuiltinPolicies` honours ahead of the
enabled set. That closes the three ways the old pair could go dark without
anyone noticing: a name absent from `enabledPolicies`, an active session pause
(`handler.ts` passes `[]`), and a config file that fails to parse
(`hooks-config.ts` soft-fails to `{enabledPolicies: []}` at five sites, so
corrupting one file disabled every policy including these two).
`policies --disable block-failproofai-commands` now refuses with a reason
instead of editing the config and reporting a success that changes nothing.
`policy-catalog.ts` now holds the metadata — name, description, category, `match`, `defaultEnabled`, `params` — as pure literal data, and `builtin-policies.ts` keeps the 39 implementations and joins them back on. `BUILTIN_POLICIES` keeps its exact shape, fields and order, so none of its nine source consumers change. This is what lets a machine list, search and render the catalog offline once the executable half moves to a fetched pack. Two constraints made the refactor narrower than it looks, and both were measured rather than assumed. `audit/cache.ts` hashes `fn.toString()` for all 39 policies into the audit cache's `engineVersion`, and `bun build` renames colliding top-level identifiers by module EMISSION ORDER — those renamed names appear inside policy bodies in the shipped bundle (`cwdWithSep2`, `execSync2`, `resolved3`). So inserting a module into the graph could have changed the emitted text, invalidated every user's audit cache and forced a ~104-second cold rescan on upgrade. Built before and after and compared: `engineVersion` is unchanged at `c1cea4ddf3030af4`. `SECRET_PATTERNS` stays here rather than being reclassified as catalog data. It is assembled from the very RegExps the five `sanitize-*` policies test against and is imported by the audit redactor, so moving it would have forced a catalog→implementation value edge and put an import cycle on the hook path. `policy-catalog.test.ts` pins the join against the failures that are otherwise silent, each verified to fail when the join is mutated: a wrapper collapsing 39 distinct `fn.toString()` hashes into one and freezing the cache key; a sort or regroup changing which policy name is attributed on a deny; a spread default-filling `beta`; a dropped row shrinking the catalog invisibly to `manager.ts` and `install-prompt.ts`, neither of which reads `.fn`. The bijection check throws at module load rather than warning, because a name with no implementation yields `fn: undefined`, whose `TypeError` `policy-evaluator.ts` swallows — the hook would allow, exit 0, and still report the policy as having run.
A pack is one digest-pinned entry artifact plus a manifest describing what it contains, installed under ~/.failproofai/policies/packs/ beside the cloud artifacts and loaded through the custom-policy loader that already exists. Not a fourth loader — the same lane with a different tag. Packs are LOCAL policy. Cloud assignments are exempt from disabledCustomPolicies and from session pause because a locally-issued command must not switch off a CENTRALLY assigned policy; a pack the user installed by typing a command is not that, so it stays disableable and pausable. Copying the exemption would have been an unrelated capability arriving by copy-paste. Three refusals, each closing a silent failure: - A pack policy name may not contain `/`, and pack policies register under `pack/<id>@<version>/`. Verified live that without this a pack shipping the name `failproofai/block-sudo` REPLACES the compiled builtin — normalizePolicyName passes any name containing a slash through untouched and registerPolicy replaces by canonical name — so the machine would report block-sudo as enabled while running a stranger's code. - A pack may not declare `alwaysOn`: downloaded enforcement that no local command can turn off. - Byte-identical packs merge toward enforcement, with a warning. Artifacts are content-addressed, so identical source is one file, and the loser would otherwise vanish with its effect deciding nothing. Same collision that once silently downgraded a cloud policy to observe-only. Manifest and artifact are reconciled after load. The artifact is digest-pinned so what it registers is what the publisher shipped, but nothing bound the manifest to it: a declared policy the artifact never registers is a listing claiming protection that does not run. engineVersion, which keys the audit cache, folds in each pack's id|version|sha256 — by identity, not source text, because the loader rewrites a per-load temporary filename into every import specifier and hashing that would cold-rescan the whole history every run. A machine with no packs hashes byte-identically to a build with no pack support, verified at the source level and in the shipped bundle (c1cea4ddf3030af4, unchanged), so this costs no existing user the ~104-second rescan. Failure is per pack, not per manifest, and fails open with a recorded reason. That is sound only while the builtins still ship compiled in and keep enforcing underneath, and the catch says so — because the day builtins become a fetched pack, this exact behaviour is zero enforcement on a machine reporting healthy.
The params schema now travels on the RegisteredPolicy, next to `match`, instead
of being looked up by name in a map built from BUILTIN_POLICIES.
That map could only ever describe policies compiled into this build, so every
pack policy, cloud assignment and custom hook fell through to the branch that
never calls getConfigParamsFor. The consequence was worse than missing defaults:
the user's OWN configured policyParams for those policies were discarded. A
person who set protectedBranches on a cloud-assigned policy had it silently
ignored, with nothing anywhere reporting it.
A schema-less policy now receives whatever the user configured, and still `{}`
when they configured nothing — which is every case that exists today. A policy
declaring a schema gets defaults merged under the user's values, unchanged.
Registration-carried rather than name-keyed also closes a hole the pack lane
opened one commit ago: a name-keyed schema was handed to ANYTHING registered
under that name, so a pack that took the `block-sudo` name would have inherited
its params along with it.
policy-evaluator.ts no longer imports the builtin catalog. That is a module
graph change, which is the condition that can shift emitted text and move the
audit cache key, so it was re-measured rather than assumed: the shipped
engineVersion is still c1cea4ddf3030af4.
`failproofai pack add | remove | list`. A pack is fetched from a GitHub release by github:owner/repo@tag, verified against that release's SHA256SUMS, written to a content-addressed artifact, and activated by an installed.json written LAST and atomically — so until that rename lands, the downloaded file is one nothing points at. The tag is required and there is no `latest`. A moving source would change what a machine enforces whenever the publisher pushed, which is the drift the recorded digest exists to prevent. Every URL is constructed from what the user typed: no API call, no releases/latest redirect to follow, no rate limit, and no way to end up holding an artifact from a source nobody named. What the verification buys, stated precisely: SHA256SUMS ships in the same release as the artifact, so it is not a signature and proves nothing about publisher identity. It proves the bytes are the ones that release published — and because the digest is recorded at add time and re-verified before every import, a pack cannot change under a machine afterwards. A repository that retags or replaces an asset stops loading rather than silently running something else. Signing was considered and deliberately deferred. A pack is validated with the LOADER's own rules at add time, while nothing has been written. So a pack declaring alwaysOn, or a policy name that would reach the failproofai/ namespace and replace a builtin, is refused before it can install cleanly and then fail silently on the next tool call. `--only a,b` takes part of a pack. The choice is stored per-pack rather than as disabledCustomPolicies entries, because those are keyed by pack:<id>@<version>:<name> — an upgrade stops matching them and everything the user deliberately left off comes quietly back on. Re-adding at a newer version carries the selection forward. `pack list` marks every policy on or off, including the ones not taken, and exits non-zero naming any installed pack that will not load: a machine enforcing less than its manifest claims is the state a person most needs told about. FAILPROOFAI_NO_DOWNLOAD refuses to fetch while installed packs keep enforcing. FAILPROOFAI_PACK_BASE_URL points at a mirror, or at the local HTTP server the tests serve a real release layout from.
`pack add` accepted two spellings, and the one anyone would actually try — pasting a release URL out of the browser — errored. It now takes `acme/support`, `acme/support@v2.1.0`, `github:acme/support@v2.1.0`, the `releases/tag/...` and `releases/download/...` URLs, and the bare repository URL. A tag containing slashes survives both URL shapes. Naming no tag resolves the newest release and pins it. The rule that mattered was never "the user must type a tag" — it is that what the machine RECORDS names exactly one release, so a reinstall cannot drift. So resolution happens before anything is written and the concrete tag is what lands in installed.json. The tag is read from the redirect `releases/latest` already issues, not from api.github.com: same origin as the assets, no second host to reach, no 60-per-hour unauthenticated rate limit, and it still honours FAILPROOFAI_PACK_BASE_URL — which is the only reason a mirror, or the test server, works at all. The pin is enforced by the type system rather than by care: packAssetUrl and formatPackSpec take a PinnedPackSpec, so a URL cannot be built from a spec whose tag was never resolved. And when a tag was resolved rather than typed, install says so and names it — running the same command tomorrow can install something different, which should be visible at the time rather than discovered later.
Packs were covered at the unit level — the manifest parses, the loader tags the hooks, the digest verifies — and none of that answers the only question a user has. The layers in between (config merge, registration order, the per-CLI response shape) are exactly where a policy silently becomes decorative. So this drives the real binary against a pack installed the way `pack add` leaves one: - a pack policy denies with enabledPolicies: [], so it is demonstrably the only guard in play rather than riding on some builtin being switched on; - a policy left out by --only does not fire, even though the artifact registers it; - `observe` runs without denying; - a tampered artifact stops enforcing rather than running altered code; - and a corrupt pack manifest leaves the builtins still denying — the layering property that makes the pack layer's fail-open defensible at all.
`readInstalledPacks` resolves through fp-home, so unmocked it reads the real ~/.failproofai/policies/packs of the machine running the suite. These four drive evaluateHookEvent for real and mock cloud-managed-policies but not this, so they pass on a clean checkout and would behave differently on a developer machine that happens to have a pack installed — the kind of green suite that stops meaning anything on exactly one person's box. Mocked to an empty result, with the reason at the mock so it does not read as boilerplate someone can tidy away.
Two misreports, both found by running the code rather than reading it. An observe-mode pack measured nothing while reporting healthy. The observe path took its shadow record from `cloudManaged!.id` — a non-null assertion that is false for a pack — so the first non-allow verdict threw. That throw escapes before the wrapper's own try, so policy-evaluator swallowed it and continued: nothing reached `observed`, and the row read as a clean allow. Reproduced exactly: `undefined is not an object (evaluating 'cloudManaged.id')`, exit 0. Which is the failure observe mode exists to prevent — and the e2e test covering it passed against the bug, because a crash and a correct observe both end in an allow. It now asserts a clean stderr too, and was checked against the old code to confirm it fails there. `observed.version` widens to string | number: a cloud deployment is a number, a pack carries a version string. Separately, `policy_evaluation_error` — the event whose whole purpose is surfacing regressions in the policies WE compile in — was gated on a list of prefixes that are not builtins, naming only `custom/` and `.failproofai-`. So `pack/…` and `cloud/…` failed the test and fired it under a publisher-controlled policy name. Now a positive test: a builtin is exactly a policy in the `failproofai/` namespace, so the next source kind cannot re-open this by omission.
`bun run build:pack` emits exactly what a third-party publisher uploads: a manifest, one bundled entry artifact, and a SHA256SUMS. It ships in the tarball beside pi-extension/ and openclaw-plugin/. Nothing on the hook path reads it. Its entire job is to be compared — which is what turns "move the builtins out of the package" from a leap into a switch somebody already ran. builtin-pack-conformance.test.ts loads it through the pack lane and asserts identical VERDICTS to the compiled implementations over a 20-call corpus, plus a guard that the corpus actually makes policies deny; without that the comparison could pass by agreeing that everything allows. It generates the pack itself rather than assuming `policy-pack/` exists, because `test` and `build` are separate CI jobs — a test depending on the build having run would be green locally and meaningless in CI. Writing that test also caught its own harness: the first run loaded 43 policies, not 38, because a repo-root sessionCwd made convention discovery pick up this repo's own dogfood policies. 38 of 39: block-failproofai-commands is alwaysOn and pack-manifest.ts refuses any pack declaring it, so including it would produce a pack our own loader rejects. One file, because only the ENTRY is content-addressed — transitive local imports are rewritten with no integrity check of their own, so a multi-file pack could not honestly claim to be digest-pinned. The generator runs under bun. It imports policy-catalog.ts directly, which node cannot resolve before 22 and which on 22 "works" while printing a reparse warning — green on this machine and broken on a version we support. policy-pack is on the standalone prune list for the same reason the extension directories are: shipped from the package root by `files`, it would otherwise land in the tarball twice. Checked with a full rebuild — three files, once each.
Both branches of promptPolicySelection built their answer out of BUILTIN_POLICIES — the non-TTY path by intersecting preSelected with it, the interactive picker by resolving from rows that come from the same catalog. manager.ts writes that answer straight into enabledPolicies and then prints only the survivors, so the loss had nothing on screen to announce it. Reproduced: a config enabling `block-sudo`, `failproofai/block-sudo` and a pack policy came back holding only the first. The qualified spelling is one the ENFORCEMENT path explicitly accepts — registerBuiltinPolicies canonicalizes both — so this deleted a working configuration, today, with no pack involved. A beta policy enabled with `--install --beta <name>` was erased by any later plain `--install` in the same way. Both branches now carry unrecognised names through untouched, which is the rule the setup wizard already follows: subtract what you can explain, never intersect with a catalog. The picker names what it kept rather than counting it — "3 kept" reads as fine right up until someone needs to know which three. Carrying an unknown name costs nothing: registration looks names up in a Set and finds nothing. Dropping one destroys configuration. Landing it before packs are installable is the point — the fix has to exist before anything starts writing a new shape of name into that file.
`pack` was in scope where the activity row's source is decided and simply not consulted, so every pack deny was written as "custom" — which is also what a user's own local .mjs gets. The two were separable only by re-parsing the `pack/` prefix off our own display name, which is precisely the practice these attribution fields were added to replace. Rows now carry policySource: "pack" with packId and packVersion, mirroring the cloud pair, so "which pack, which version decided this" has an answer that is not string surgery. The policySource union, HookActivityFilters.source, and all four dashboard sites move together: the state union, the URL-param validation, the onChange revalidation and the option list. The validation one matters on its own — it silently drops a value it does not recognise, so a shared ?source=pack link would have quietly resolved to "all sources". No Rust change needed. policy_source is an Option<String> forwarded verbatim, so a new source on this side needs no coordinated release; the doc comment now says that is deliberate and that the comment going stale is the trade.
`pack add` enabled every policy in a pack. So installing the builtins pack switched on all 38 when only 10 are defaultEnabled — turning on block-kubectl, block-terraform, require-ci-green-before-stop and 25 others that the npm package leaves off precisely because they interrupt legitimate work. The pack carried that opinion in its own manifest and the installer replaced it with one nobody held. No flag now means the pack's declared defaults. --all takes everything. --category x,y takes whole categories by slug (sanitize, dangerous-commands, packages-system, …). --only a,b still takes exact names, and the two compose as a union, kept in the pack's declared order rather than the order the flags happened to name them. An unknown category lists the ones that exist. --all is recorded as "the whole pack" rather than as the names that existed at install time, so a later version's new policies are included instead of being silently frozen out. An explicit selection is still carried forward across an upgrade. The summary says how many of how many and WHY that set is on — "10/38" alone reads like a failure — and caps the not-enabled list at six names plus a count, instead of the 37-name wall and 400-character suggested command it printed before. `pack list` groups by category and shows each slug, because a flat list gives no clue the flag exists.
The tarball already ships policy-pack/ — the builtins as a real, digest-verified pack. installBundledPack() copies it into ~/.failproofai/policies/packs/ from disk. This is what makes removing the builtins from the bundle survivable. A machine that just installed failproofai already has them, so a fresh offline install is a guarded machine rather than one enforcing nothing while reporting healthy. Three things it does deliberately: - Verifies the digest even though nothing crossed a network. The recorded digest is what the hook path re-checks before every import, so it must describe the bytes actually installed, and a tarball can be corrupt on disk like anything else. - Validates the manifest with the LOADER's own rules, so a bundled pack that could never load fails the install instead of looking fine until the next tool call. - COPIES the artifact rather than loading it in place. A `sudo npm i -g` package dir is root-owned and the loader writes its rewritten tree beside the source, so loading in place gives a non-root hook EACCES and the pack silently never loads — the same trap #694 fixed for the shim. Anchored at FAILPROOFAI_PACKAGE_ROOT, not import.meta.url, which does not survive the CJS bundle. Recorded with a `bundled:` source, because `pack add` on that id would otherwise look like a re-fetch of something never fetched.
Every content-load failure in this codebase fails open. That was sound while the builtins shipped compiled in and kept enforcing underneath. Once a pack can be the only thing between an agent and a machine, the same behaviour is zero enforcement at exit 0 on a machine that reports healthy. The trigger is a RECORDED EXPECTATION, never an empty manifest. An absent installed.json is a fresh machine and stays silent; a pack that is declared and will not resolve, or that registers less than it declared, denies. Six carve-outs, each closing a way this deny would be wrong: - an observe pack, which evaluates and discards by construction, so denying on its behalf denies for something that would have allowed; - policies the user never took, and policies explicitly disabled — denying for a guard that was never going to run is denying on nobody's behalf; - a pack the loader never received, because inferring failure from "no registrations" cannot separate an import error from a pause skip, and a heuristic that DENIES is worse than one that allows; - an active session pause, or a registration-derived check fires on every paused event and converts a bounded, deliberate pause into a machine-wide deny; - a load timeout, which is transient — one slow disk moment would otherwise deny until a human intervened, and in the warm worker the denials add load. The deny is narrow. An unreachable daemon is correctly total: no evaluation happened, so nothing can be known safe. An unloadable pack is not — its missing guards are enumerable, because every declared policy carries a match — so it denies only where those policies applied. UserPromptSubmit instructs instead, whatever a missing policy declared. A blanket deny takes it along and locks the user out of the agent that could fix the problem; it is the one event that can tell a human what happened. Mechanism: registered as a policy, never a hand-rolled exit code, because a bare exit-2 is a silent ALLOW on eight CLIs. Additive rather than clearing the registry, so a corrupt third-party download cannot switch off the alwaysOn guard. Priority above builtins, so the deny is attributed to the missing pack.

The runtime reader requires the stricter two-segment ID and version regex (src/hooks/pack-manifest.ts:169).

Required change: Share or expose the installed-record validation and apply it in fetchPack() before writing the artifact or installed.json; validate ID, version, and effect with the same rules as parsePack(). Add tests for invalid ID, version, and effect asserting no activation file is written.

Inline comments:
In `@__tests__/audit/engine-version-packs.test.ts`:
- Around line 83-90: Add a unit test alongside the existing engineVersion cache
tests that installs the same pack id and version with a changed sha256 digest,
resets modules, and asserts engineVersion changes; keep the id and version
identical so the test isolates digest-based invalidation.
In `@__tests__/hooks/pack-manifest.test.ts`:
- Around line 66-69: Make the test callback for “returns nothing, and no error,
when no pack was ever installed” asynchronous and await the promise returned by
the resolves assertion on read(), ensuring assertion failures are properly
enforced.
In `@bin/failproofai.mjs`:
- Line 711: Update the help guard before runPackCommand to detect --help or -h
anywhere in subArgs, so nested commands such as pack add --help enter the
existing help path instead of executing add. Preserve the current help behavior
for top-level flags.
In `@CHANGELOG.md`:
- Line 25: Update the pack-add changelog entry to state that the tag is optional
and that omitting it resolves and pins the newest release, consistent with the
behavior described on line 23. Remove the conflicting claim that the tag is
required and that no latest resolution occurs, while preserving the remaining
digest and immutability details.
In `@crates/fpai-collect/src/sources/hooks/transform.rs`:
- Around line 66-75: Add serde-mapped pack_id and pack_version fields to
HookRow, then propagate both values through the transform output model alongside
policy_source. Preserve the existing optionality and JSON names packId and
packVersion so pack identity survives collection and deserialization.
In `@docs/reference/failproof-cli.mdx`:
- Line 65: Update the local-pause description near “Local pauses” to explicitly
state that pack policies are suspended for the session, alongside builtin,
custom, and convention policies, while preserving the existing expiration and
Cloud-managed policy behavior.
In `@src/hooks/fp-home.ts`:
- Around line 597-603: Update the reset or setup flow to call installBundledPack
after resetHome removes packs/, ensuring the bundled pack is restored and
builtin enforcement remains available; locate the change using resetHome and
installBundledPack, and preserve existing pack-add behavior.
In `@src/hooks/handler.ts`:
- Around line 376-382: The custom-hook loading flow around loadAllCustomHooks
must expose per-pack import failures, including packs that produce no hooks
after manifest validation. Return the failed pack IDs from loadAllCustomHooks
and pass them to missingGuards so those enforced packs register
pack/failproofai-pack-unavailable; preserve successful pack registration
behavior.
In `@src/hooks/pack-cli.ts`:
- Around line 34-43: Update add to identify the pack source only from arguments
not consumed as values by --only or --category, following the
consumed-flag-index approach used by policies --install in bin/failproofai.mjs.
Ensure commands such as --only block-refunds acme/support-agent select
acme/support-agent as the source while preserving existing validation for
missing or empty flag values.
In `@src/hooks/pack-store.ts`:
- Around line 271-283: Export PACK_ID_RE and PACK_VERSION_RE from
pack-manifest.ts, then update fetchPack at src/hooks/pack-store.ts lines 271-283
and installBundledPack at lines 486-491 to use those shared patterns and reject
policy effects other than enforce or observe; both sites require the same
validation as the loader.
- Around line 191-202: Update fetchBytes to enforce MAX_ARTIFACT_BYTES before
buffering: reject responses whose content-length exceeds the limit, then read
response.body incrementally while counting bytes and aborting once the cap is
reached, finally returning the accumulated Buffer only when within bounds.

Nitpick comments:
In `@app/policies/hooks-client.tsx`:
- Around line 484-486: Extract the policy-source values into a single shared
constant and derive the filterSource type and validation from it. Update the URL
initializer, onChange validation, and option rendering to reuse that constant so
adding a source requires only one change, while preserving the existing
empty-string fallback for unknown URL values.
In `@bin/failproofai.mjs`:
- Around line 698-708: Move the harness command documentation so it directly
precedes the if branch checking args[0] === "harness", placing the pack command
documentation immediately before its own branch and keeping each comment block
associated with the correct command.
In `@scripts/build-policy-pack.mjs`:
- Line 61: Update the ESM specifiers at both import sites in the build-policy
script to convert filesystem paths with pathToFileURL(...).href before
interpolation, including the BUILTIN_POLICIES import and the corresponding
specifier near the second path usage. Preserve the existing resolved paths while
ensuring Windows paths use file URLs.
- Around line 59-72: Preserve the generated pack entry and its current policy
registration shape. If custom policies need matcher parameters, update
CustomHook to use PolicyMatcher, add params, and forward hook.params for
non-pack registrations through registerPolicy; do not modify the generated
entry.
In `@src/hooks/pack-cli.ts`:
- Around line 41-43: Update the flag validation in the CLI parsing flow
containing all, only, and categories to fail when --all is combined with either
--only or --category, before selection resolution proceeds. Preserve the
existing validations for empty --only and --category values and use the
established fail path with a clear conflict message.

Do not complete the reset after bundled-pack restoration fails.
installBundledPack() can return installed: false for corrupt assets or invalid bundled metadata. This result is ignored, and Line 987 still writes the layout version. The reset then completes without the bundled enforcement pack and will not retry automatically.
Handle installation failure before writing the version marker. Keep the documented no-bundled-pack build path separate from integrity or validation failures. Add a reset test for a corrupted bundled asset.

Treat absent registrations as missing policies.
A resolved pack is handed to the loader. If its artifact imports successfully but registers zero hooks, failed has no entry and registered has no entry. Lines 141-145 then skip the pack, so its enforced declared policies receive no fail-closed guard. The same state occurs for a second pack that shares a deduplicated artifact path.
Use an empty registration set when no set exists. The existing taken and disabled filters then prevent guards for intentionally unselected or disabled policies. Add coverage for an enforce pack whose module imports but registers no hooks.
