📝 WalkthroughWalkthroughThis change moves policy enforcement and management to installed policy packs. It adds pack validation, integrity checks, loading, fail-closed handling, CLI and dashboard workflows, audit integration, attribution, shared TUI rendering, and an always-on self-protection policy. ChangesPolicy pack architecture
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This change reorganizes policy setup, installation, publishing, and enforcement, but the current version can disable existing protections, execute a rejected pack before refusing it, bypass safeguards on some commands, and mis-handle or lose selected policies; required CI preparation is also incomplete. These correctness and security risks should be fixed before merging. Suggested reviewers: Poem

Hermes found blocking issues that should be addressed.
Review coverage was incomplete, but the concrete blocking findings below are sufficient to request changes.
High: Pack policy parameters saved by the dashboard are never applied
- Rule:
COR-001 - Location:
src/hooks/policy-evaluator.ts:45 - Evidence: The dashboard reads and writes parameters using the manifest policy name (get-hooks-config.ts:261 and update-policy-params.ts:12), for example
policyParams["block-sudo"]. The hook handler registers that same pack policy aspack/<id>@<version>/<name>(handler.ts:533-543). policy-evaluator.ts:45-49 only looks up that qualified registered name and permits a short-name fallback exclusively forfailproofai/policies. Thus a configured pack policy receives schema defaults (or{}) instead of the value the UI displays as saved; this affects the bundled core pack immediately after migration. - Required change: Carry a stable configuration key from the pack manifest into the registered policy and look it up during evaluation, or consistently use a namespaced pack key in both the dashboard and runtime. Preserve a documented compatibility lookup for existing core-policy parameter keys, and add an end-to-end test that changes a pack policy parameter and observes it in
ctx.params.
High: Identical pack artifacts silently discard another pack's selected policies
- Rule:
COR-001 - Location:
src/hooks/custom-hooks-loader.ts:451 - Evidence: custom-hooks-loader.ts:451-465 collapses all installed packs sharing an artifact path to one
ResolvedPack. The winning record alone tags hooks at lines 502-504, and handler.ts uses only that tag'senabledselection to decide whether each hook registers. A user can install two distinct pack IDs publishing identicalfoo/barartifact bytes, select onlybarfrom the first and onlyfoofrom the second;foofrom the second pack is never registered. pack-failclosed.ts:141-145 explicitly ignores a pack absent from the registered map, so this becomes a silent enforcement gap despite the second pack being recorded as enabled. - Required change: Do not collapse packs solely by artifact path when their selections or identities differ. Either register/evaluate each pack's selection independently while sharing one module import, or merge the selected policy sets and preserve per-pack attribution; if that cannot be represented safely, reject the conflicting installation. Add a regression test with two IDs sharing bytes and complementary
--onlyselections.

Hermes found blocking issues that should be addressed.
Review coverage was incomplete, but the concrete blocking findings below are sufficient to request changes.
High: Pack policy parameters saved by the dashboard are not applied
- Rule:
COR-001 - Location:
src/hooks/policy-evaluator.ts:45 - Evidence: The dashboard reads and writes parameters under the manifest's bare policy name (app/actions/get-hooks-config.ts:261 and app/actions/update-policy-params.ts:12). The handler registers a pack policy as pack/@/ (src/hooks/handler.ts:517-543). src/hooks/policy-evaluator.ts:45-49 only accepts a bare-name fallback for the failproofai/ namespace, so a pack policy receives schema defaults or {} instead of the saved value. This affects the bundled core pack after migration.
- Required change: Give registered pack policies a stable configuration key and resolve it in the evaluator, or use the versioned pack key consistently in both UI and runtime while retaining compatibility for existing core keys. Add an end-to-end test that changes a pack parameter and observes it in ctx.params.
High: Identical pack artifacts silently omit another pack's selected policies
- Rule:
COR-001 - Location:
src/hooks/custom-hooks-loader.ts:451 - Evidence: src/hooks/custom-hooks-loader.ts:451-465 collapses every pack sharing an artifact path to one record. Only the winning record tags the imported hooks, and src/hooks/handler.ts:428-453 applies only that record's enabled selection. Two pack IDs sharing a foo/bar artifact and selecting foo and bar respectively therefore register only the winner's selection. src/hooks/pack-failclosed.ts:105-110 deliberately ignores a pack absent from the registered map, so the omitted selected policy does not trigger the fail-closed guard.
- Required change: Do not collapse distinct pack identities solely by artifact path. Import once if needed, but apply each pack's selection and preserve per-pack attribution; alternatively reject conflicting installations. Add a regression test using complementary selections on two IDs sharing one artifact.
1 advisory finding
- High/High A remote pack can replace the bundled core pack by claiming its ID — installBundledPack records the trusted core pack as bundled:failproofai/core@ (src/hooks/pack-store.ts:762-773). In addPack, the source-binding refusal explicitly excludes any prior bundled source (src/hooks/pack-store.ts:631-640). Thus a release from an arbitrary repository declaring id failproofai/core is accepted and upsertInstalled replaces the bundled record. On subsequent events the migration shim is disabled because a pack is present (src/hooks/handler.ts:316-322), while only the attacker's declared subset is enforced. (

hooks remain available after the audit.
In `@src/hooks/custom-hooks-loader.ts`:
- Around line 304-305: Update the custom hook loading flow around loadSingleFile
and packFailures so every successfully processed artifact that registers zero
hooks is explicitly represented as an empty registration result, allowing
pack-failclosed missingGuards to enforce manifest policies. Preserve existing
failure entries for import errors and missing paths, and ensure handler
registration data distinguishes a handed-over pack with no hooks from a pack
never processed.
In `@src/hooks/handler.ts`:
- Around line 316-332: Resolve the pack-versus-builtin deduplication contract
around registerBuiltinPolicies and enabledBuiltinNames: ensure the dedup set
reflects the builtin policies actually registered when packs are installed, so
the existing “builtin wins” check can skip duplicate pack policies; update the

In `@src/hooks/pack-cli.ts`:
- Around line 109-119: Update build to compute consumed argument indices for its
own value-taking flags—id, version, effect, out, and entry—before selecting the
positional entry, rather than relying on packAddSource. Ensure flag values are
excluded from positional entry detection so commands with flags before the entry

Hermes found blocking issues that should be addressed.
Review coverage was incomplete, but the concrete blocking findings below are sufficient to request changes.
High: Remote packs can replace the bundled official pack
- Rule:
SEC-001 - Location:
src/hooks/pack-store.ts:710 - Evidence:
addPackonly rejects a source change when the prior record is notbundled:(src/hooks/pack-store.ts:710-718). Therefore, aftercorerecordsbundled:failproofai/core@…, a remote release whose manifest declaresid: "failproofai/core"passes this guard.upsertInstalledthen replaces the record with the same ID (src/hooks/pack-store.ts:980-984), silently activating the remote artifact in place of the official one. The adjacent test covers only a prior GitHub source, not a bundled source (src/hooks/pack-build.test.ts:264-273). - Required change: Bind bundled IDs to their trusted source as well. Reject a remote source with an installed bundled ID unless the user explicitly removes it first, or allow only a designated official repository as an intentional migration path. Add a regression test installing the bundled pack before attempting a same-ID remote install.
High: Dashboard pack parameter changes are ignored at enforcement time
- Rule:
COR-001 - Location:
app/policies/hooks-client.tsx:1388 - Evidence: The dashboard displays and saves parameters under the short manifest name:
currentParamsreadsconfig.policyParams[policy.name](app/actions/get-hooks-config.ts:261) and the client sends that same short name toupdatePolicyParamsAction(app/policies/hooks-client.tsx:1381-1388), which persists it unchanged (app/actions/update-policy-params.ts:11-13). Pack policies are registered aspack/<id>@<version>/<name>(src/hooks/handler.ts:517-534), while the evaluator accepts only that exact key and allows a short-name fallback solely forfailproofai/policies (src/hooks/policy-evaluator.ts:40-49). Consequently, changes made in the dashboard are shown as saved but the pack continues receiving defaults. - Required change: Use one canonical pack policy key (
pack/<id>@<version>/<name>) for dashboard reads and writes, or extend the evaluator with an unambiguous pack-aware key scheme. Add an end-to-end test that changes a pack parameter through the dashboard path and verifies the registered policy receives it.

- Around line 47-64: Update the test setup around cli and the test-run workflow
to build the bundled policy pack with bun run build:pack before bun run
test:run, ensuring policies add core has the required artifact. Include the
combined r.all output in failure messages so both stdout and stderr are visible
when tests fail.
In `@CHANGELOG.md`:
- Line 7: The changelog entry should distinguish removing the hardcoded
policy-selection wizard from removing policy installation: state that setup
still installs the selected bundled pack and retains the always-on Failproof AI
self-protection guard, while no longer preselecting the broader policy set.
Update the “wires the hooks and stops” and “ships no policies” wording
accordingly, preserving the existing scope-carryover and customPoliciesEnabled
details.
In `@src/hooks/configure-wizard.ts`:
- Around line 992-993: Update the apply loop in the configure-wizard flow to
read enabledPolicies separately for each selected scope by calling
readScopedHooksConfig(scope, cwd).enabledPolicies ?? [] inside the loop. Remove
the shared primaryScope-derived policies value so applying both scopes does not
clear the user scope or disable legacy builtins when project configuration is
absent.
In `@src/hooks/pack-cli.ts`:
- Line 435: Update the publish entry-path resolution around packAddSource so
values consumed by publish flags—including --repo, --version, --id, --tag,
--notes, --out, and --effect—are excluded before selecting the positional entry.
Compute consumed argument indices from the complete publish flag set rather than
reusing packAddSource’s narrower filtering, while preserving --dry-run handling.
- Around line 126-131: Update build’s argument parsing to use the parsed --repo
value as the fallback when --id is absent, matching publish’s behavior while
preserving explicit --id precedence and the existing usage validation.
In `@src/hooks/tui.ts`:
- Around line 526-528: Update hintBudget to return zero when the label leaves no
available hint space, while retaining the minimum six-column budget when space
remains. In both picker rendering paths that use hintBudget, omit the hint
prefix and clipped hint text when the returned budget is zero so the full label
is not extended past the row.
- Around line 194-197: Update the fg function so HUES.dim preserves its SGR dim
attribute at the truecolor tier instead of returning a truecolor foreground
sequence; keep normal truecolor hues using their RGB values and retain existing

Review coverage was incomplete, but the concrete blocking findings below are sufficient to request changes.
High: A remote manifest can replace the bundled core pack
- Rule:
SEC-001 - Location:
src/hooks/pack-store.ts:710 - Evidence:
addPack()obtains a prior record by self-declared id atsrc/hooks/pack-store.ts:672. Its intended source-binding check explicitly skips bundled records at lines 710-713. Therefore, aftercoreis installed, a release fromgithub:attacker/repowhose manifest declaresid: "failproofai/core"passes the check andupsertInstalled()replaces the bundled record by id. Its selection is then calculated against the attacker's manifest, so existing core protections can disappear while the record still appears to be the core pack. - Required change: Reserve
failproofai/corefor the bundled/official provenance and reject source changes for it. More generally, bind pack ids to a trusted source on first installation and require explicit removal before a different source can claim that id; handle the legacy builtins-to-core rename through explicit migration metadata rather than digest/id fallback.
2 advisory findings
- High/High State deletion guard misses
find -delete— The always-on guard atsrc/hooks/builtin-policies.ts:1483only testsFAILPROOFAI_STATE_WRITE_RE, whose verbs arerm|unlink|shred|mv|truncate. An agent can runfind ~/.failproofai -delete(orfind $HOME/.failproofai -delete), which does not match that guard. The same file already recognizesfind ... -deleteinrecursiveDeletionTargetsat lines 1153-1171, but that belongs to the optionalblock-rm-rfpolicy. Deletinginstalled.jsonremoves all selected pack policies; on a newly configured machine there are no legacy enabled builtins to restore them. (src/hooks/builtin-policies.ts:1483) - High/High Pack policy parameters saved by the dashboard are ignored at runtime — The dashboard exposes each pack policy under its bare name (
app/actions/get-hooks-config.ts:242) and saves parameters under that bare key (app/policies/hooks-client.tsx:1383-1388;app/actions/update-policy-params.ts:12). At evaluation, however, the policy is registered aspack/<id>@<version>/<name>, andgetConfigParamsFor()atsrc/hooks/policy-evaluator.ts:45-49only falls back from the defaultfailproofai/namespace. ThuspolicyParams["block-sudo"], including existing user configuration and values just saved by the dashboard, is never passed to the core pack'sblock-sudoimplementation; it runs with defaults instead. (src/hooks/policy-evaluator.ts:45)
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:
- F5 State deletion guard misses
find -delete(src/hooks/builtin-policies.ts) — noticed at round 4, on code that had not changed since the round before, so it never blocked - F3 A remote manifest can replace the bundled core pack (
src/hooks/pack-store.ts) — noticed at round 2, on code that had not changed since the round before, so it never blocked - F6 Pack policy parameters saved by the dashboard are ignored at runtime (

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.

`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.

…spell
The floor that told an aimed pattern from an ordinary one was a literal `fail`
substring test, which is precisely the letter a metacharacter stands in for.
`rm -rf ~/.f*ailproofai` was thrown out before it was ever compiled, and so
were `.[f]ailproofai`, `.fa*lproofai`, `.fa[i]lproofai` and `.f{a,b}ilproofai` —
every one of them deleting the state through the guard nobody can switch off.
The floor is now computed the same way the match is: compile once, require that
the pattern hits the state, and reject it if it also hits anything ordinary.
That keeps `rm -rf *` and `rm -rf ~/.*` allowed — they sweep the decoys too, and
an always-on guard that denied those would be worked around by the first person
who met it — while `rm -rf /tmp/test-failures*` stays allowed for the older
reason, that it reaches no state path at all. Braces are compiled as the
alternation they become, and every `/`-prefix is tried rather than the whole
token: naming a file inside the state is naming the state.
The second half is the same mistake one layer up. `match` was validated as "is
an object" and nothing more, so a manifest declaring `events: "PreToolUse"` was
iterated character by character and narrowed the fail-closed deny to
["P","r","e","T","o","l","U","s"] — a guard matching no event that exists. The
pack failed to load, the deny fired on nothing, and the machine reported
enforcement it did not have. `events: 5` threw `number is not iterable` on the
hook path outright. Metadata nobody can read now widens the deny instead of
narrowing it, because a scope derived from something unparseable says nothing
true, and the manifest refuses the shape at install time where the publisher can
still fix it.
The test that pinned the glob bypass as a known gap is removed: it is no longer
a gap, and the cases that replace it cover both directions.

@hermes-exosphere review Round 5 findings addressed at F9 — glob syntax bypasses the always-on state guard. The floor deciding whether a pattern was aimed at the state was F10 — malformed pack match metadata defeats fail-closed enforcement. Confirmed and fixed at both layers. Two earlier findings were already fixed before this round and I re-verified rather than re-fixing: Not fixed, by the maintainer's explicit decision: the hook-config gap ( Gates green locally: tsc 0, lint 0 errors, build exit 0, e2e 333/333, unit 4770 passed (9 failures are the 8 locally-emptied dogfood configs plus one cross-worker flake that passes in isolation). |

High: Nested glob in brace expansion bypasses the state guard
- Rule:
SEC-001 - Location:
src/hooks/builtin-policies.ts:753 - Evidence:
globPrefixNamesStateescapes every brace alternative atsrc/hooks/builtin-policies.ts:753. Consequentlyrm -rf ~/.f{a*,x}ilproofaiis compiled as alternatives containing a literal*, even though the shell first expands it to~/.fa*ilproofaiand then glob-expands that word to~/.failproofai. The always-onblock-failproofai-commandspolicy therefore returnsallow; this was reproduced in a nested Docker container against the reviewed source. Deleting that directory removes installed packs and can turn off their enforcement without invoking the CLI. - Required change: Expand brace alternatives before compiling glob patterns, or recursively compile metacharacters within each alternative, and add regression cases such as
~/.f{a*,x}ilproofai(including paths beneath that directory).
Compiling `{a*,x}` as an alternation of escaped literals put a literal `*`
inside the pattern. The shell does not work that way: brace expansion rewrites
the word FIRST, and only the resulting words are matched against the disk. So
`rm -rf ~/.f{a*,x}ilproofai` — which the shell turns into `~/.fa*ilproofai` and
then into the state directory itself — compiled to a pattern that could never
match it, and walked past the guard nobody can switch off.
Expansion now runs ahead of compilation, over nested groups and several groups
in one word, and it is bounded rather than trusted: `{a,b}` twenty times over
multiplies to a million words, so past the limit every group collapses to `*`.
That is a superset of what the braces could produce, which keeps an oversized
token decidable — and still held to the same decoy test — instead of turning
into a way to stall the hook path.
The other half was the token never arriving whole. `bareToken` strips leading

High: Nested brace expansion still bypasses the state guard
- Rule:
SEC-001 - Location:
src/hooks/builtin-policies.ts:752 - Evidence:
expandBracesstops after 16 rounds and returns unresolved words atsrc/hooks/builtin-policies.ts:752-770. A 17-level token such asrm -rf ~/.f{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,{x,a*}}}}}}}}}}}}}}}}}ilproofaiis valid shell brace expansion and has a branch that becomes~/.fa*ilproofai, which glob-expands to~/.failproofai. The remaining unresolved brace group is escaped byglobPrefixNamesState, sonamesStateis false and the destructivermis allowed. Deleting this directory removes installed packs and disables their enforcement. - Required change: Do not return unresolved brace groups after the depth limit. Continue expansion within a bounded global work budget, or conservatively collapse every remaining nested group into a glob representation before matching. Add a regression test with more than 16 nested brace groups that can expand onto the state directory.

- Medium/High Matching packs by artifact digest deletes independent pack records —
priorRecordFortreats any matching SHA-256 as the prior pack (src/hooks/pack-store.ts:618-620), andupsertInstalledthen removes every different ID with that digest (src/hooks/pack-store.ts:1150-1163). Two distinct packs may legitimately use identical entry bytes; the newpack-shared-artifacttests explicitly model distinct IDs with one artifact. Ifacme/first@1.0.0andacme/second@2.0.0from the same repository have identical artifacts, adding the latter passes the repository check but silently removes the former record and its independent selection. (src/hooks/pack-store.ts:1150)
The round cap RETURNED its half-expanded words. A word that still has braces in
it goes to a compiler that escapes them as literals, so seventeen levels of
`{x,{x,…{x,a*}…}}` — legal shell with a branch that becomes `~/.fa*ilproofai`,
which globs onto the state directory — came out matching nothing at all. The
budget was doing the opposite of its job: running out of it produced an ANSWER,
and the answer was "this names nothing".
Exhausting the budget now collapses instead. Every remaining group becomes `*`,
which reaches strictly more than the braces could, so the token stays decidable
however deep it goes and is still held to the decoy test that keeps `rm -rf *`
allowed. Collapsing replaces each OUTERMOST group whole rather than resolving
innermost-first — one pass at any depth, instead of one pass per level, which
would only have moved the same cliff somewhere further out. Verified to 200
levels, in both directions.
Separately, `policies add` stops stating an inference as a fact. Absorbing a
same-artifact record under another id is the right default — a publisher
renaming a set must not reset everyone who had narrowed it — but identical bytes
cannot tell a rename from a second pack one repository builds from the same
source, and the record that goes away is one the user installed on purpose.
"Same policies under a new name" claimed to know which it was. The line now
reports what was observed, that absorbing was the inference, and how to restore
the other pack when the inference was wrong.

High: POSIX-negated glob bypasses the always-on state guard
- Rule:
SEC-001 - Location:
src/hooks/builtin-policies.ts:878 - Evidence:
globPrefixNamesStatecopies a shell bracket expression directly into a JavaScript regex atsrc/hooks/builtin-policies.ts:878. Bash expands~/.f[!b]ilproofaito~/.failproofai, but JavaScript interprets[!b]as a class containing!orb, so the generated regex does not match the state candidate. ConsequentlydestroysFailproofaiState()returns false andblockFailproofaiCommands()allowsrm -rf ~/.f[!b]ilproofai, which deletes the pack/config state and disables all fetched enforcement policies. - Required change: Translate POSIX
[!...]bracket expressions to JavaScript[^...]expressions before compiling the glob (including appropriate escaping), and add a state-guard regression test forrm -rf ~/.f[!b]ilproofaiand a nested-path variant.

- Medium/High Artifact digest is incorrectly treated as pack identity —
priorRecordForfalls back from pack ID to matching SHA-256 atsrc/hooks/pack-store.ts:620. A second independently named pack with byte-identical entry code therefore inherits the first record asprior; the source binding check at line 912 then rejects it because the repositories differ. If that check did not reject it,upsertInstalledwould instead absorb and delete every different ID with the same digest (lines 1150-1153). This contradicts the shared-artifact enforcement fixture, which explicitly models distinct IDs and independent selections for the same artifact in__tests__/hooks/pack-shared-artifact.test.ts:94-107. (src/hooks/pack-store.ts:620)
POSIX negates with `!` and JavaScript with `^`, so `[!b]` — which bash expands straight onto the state directory — compiled to a class matching either `!` or `b`, and `rm -rf ~/.f[!b]ilproofai` walked past the guard that cannot be switched off. One character wide, and the pattern was read backwards. Two more spellings were being read wrong beside it. A `]` in the FIRST position is content rather than the terminator, so scanning for the next `]` closed `[]a]` on the wrong character; and a POSIX class carries a `]` of its own, which ended `[[:alpha:]]` early and left a stray literal on the end. Anything past those — a collating symbol, an equivalence class — becomes `[^/]`, which reaches at least as far as whatever it replaced. Widening is safe here in a way narrowing never is, because the decoy test is what decides. An unclosed `[` is now a literal `[`, which is what it is to a shell. It used to return false, and that is the same mistake as last time in a smaller place: a malformed pattern is not evidence that a command names nothing. The pack half is the other end of the same lookup. A prior record is found by digest as well as by id, and the origin binding — an id may not change the source it came from without an explicit removal — did not ask which of the two it had been handed. A pack from another repository that happened to build byte-identical output was refused with `pack id X is already installed from Y`, naming an id the user never asked for and offering a removal that would not have helped. It applies only when the ids actually match.

High: Extended glob bypasses the always-on state guard
- Rule:
SEC-001 - Location:
src/hooks/builtin-policies.ts:719 - Evidence:
globCouldNameState()only recognizes*,?,[, and{atsrc/hooks/builtin-policies.ts:719. Bash extended globs use@(...), which therefore never marks the command as reaching the state path. In an isolated container, invoking the productionblock-failproofai-commandspolicy forbash -O extglob -c 'rm -rf ~/.f@(ailproofai)'returned{"decision":"allow"}; Bash expands that pattern to~/.failproofaiand deletes it. Removing the pack manifest disables all downloaded policy enforcement while the guard remains the only compiled policy. - Required change: Recognize Bash extended-glob operators (
@(),?(),*(),+(),!()) when determining whether an operand can name the state directory, including commands passed through shell-c. Add a regression test that requires this command to deny.
1 advisory finding
- Medium/High A failed pack denies CLIs outside its configured scope — The handler loads every installed pack path before applying
pack.clis(src/hooks/handler.ts:400and:434). On a permanent load failure,missingGuards()creates a deny from the policy match without consideringpack.clis(src/hooks/pack-failclosed.ts:147). An isolated integration probe with a digest-mismatched pack scoped toclis:["codex"]returned aPreToolUsedenial for theclaudeCLI. That agent was never configured to be guarded by this pack, yet is locked out until a human repairs it. (src/hooks/pack-failclosed.ts:147)
…s it covers Three of Bash's five extended-glob operators begin with a character that means nothing on its own, so `@(`, `+(` and `!(` did not even mark a token as a pattern: `rm -rf ~/.f@(ailproofai)` never reached the glob check. `@()`, `?()`, `*()` and `+()` are compiled now as the groups-with-a-quantifier they are, recursing into their alternatives rather than escaping whatever is inside them, and `!()` becomes `[^/]*` — a negation a regex cannot express against a path segment, answered by widening, which is the direction that stays safe here. Underneath it was the brace bug again, wearing different characters. The strip that removes a subshell's parentheses removes a pattern's too, so the token arrived as an unterminated group. Parentheses and braces are both how a shell groups COMMANDS and how it spells a PATTERN, and both spellings end the token with the closing one. The glob scan keeps them and tries the stripped reading as well, rather than choosing one and being wrong half the time. Separately, a pack that fails to load stops denying agents it never covered. The registration path skips a pack whose `clis` excludes the running agent and the fail-closed path did not, so a pack scoped to codex that failed its digest check locked claude out too — over enforcement that agent was never configured to have, until a human repaired a pack it does not use. The scope is carried on a pack that failed before it could be resolved, and an unreadable one means every agent rather than none: `clis: "codex"` is a truthy value with a `length` and an `includes`, so the first version of this check narrowed itself away to nothing and skipped the guard everywhere. Same rule as an unreadable `match` — a narrowing nobody can parse says nothing true.

Container validation could not be provisioned. Re-run with |
Both are the same shape: a decision made in one function, consumed in another, and the consumer assuming something the producer had stopped guaranteeing. When several packs are unavailable at once, one policy stands in for all of them. Its matcher unioned the events and left `toolNames` out of the combined object entirely, which reads as "every tool" — so ONE failed pack scoped to Bash denied Bash, and TWO of them denied Write and Read as well. Combining two limited scopes was producing a larger one. Both axes union by the same rule now, narrowing only where every guard was narrow, and the merge moved next to the other match logic where it can be tested. The audit half is the same trick with a byte offset. The cache decides a transcript grew and hands back a prefix result plus somewhere to resume from, but the READER is what finds out that offset is no longer good — truncated, rewritten underneath it — and it answers by reading the whole file instead. The prefix was merged onto that regardless, so everything before the offset was counted twice and the audit reported more than the transcript held. The merge asks whether the scan actually resumed now, rather than whether a prefix existed. Those null paths are a concurrent truncation and an I/O error, neither of which a black-box audit can trigger on purpose, so the test forces the reader to refuse. Without the fix it reports five events where the file holds three.

High: Propagate a shared artifact failure to every pack that depends on it
- Rule:
COR-001 - Location:
src/hooks/custom-hooks-loader.ts:544 - Evidence: When two installed packs resolve to the same artifact, custom-hooks-loader collapses them into one packByPath entry (lines 482-517). On an import or path failure it writes packFailures only for that merged winner (line 544). missingGuards then skips every other installed pack that is absent from both the failure and registration maps (pack-failclosed.ts lines 170-193). Thus, if pack A selects a Bash policy and pack B selects a Write policy from the same artifact and that artifact has a syntax error, only A receives a fail-closed guard; B's selected Write policy is absent and Write is allowed. A focused container execution of missingGuards with that map returned only a/one.
- Required change: Retain all pack IDs represented by each deduplicated artifact path and record a permanent load failure for every one of them (including path-missing). Add an end-to-end regression with two packs sharing an artifact, complementary selections, and a failed import, asserting both policy scopes are denied.
1 advisory finding
- Medium/High Do not flatten independent event/tool scopes into a cross product — combinedGuardMatch independently unions events and toolNames (lines 237-241), while policy-registry requires both axes to match (policy-registry.ts lines 94-101). For unavailable guards scoped to (PreToolUse,Bash) and (PostToolUse,Write), the merged matcher is events=[PreToolUse,PostToolUse] and toolNames=[Bash,Write], so it also denies the unintended (PreToolUse,Write) and (PostToolUse,Bash) calls. A focused container execution registered this matcher and confirmed both unintended pairs matched. (
src/hooks/pack-failclosed.ts:241)
…t they scoped Packs with identical entry bytes collapse to one load so the module imports once. A load failure is recorded per PACK ID, and the collapse leaves one id holding the merged record — so a syntax error in a shared artifact marked the winner failed and said nothing about the other. `missingGuards` skips a pack missing from both the failure map and the registration map, so the second pack's selected policies were absent, unguarded, and unreported: exactly the silent under-enforcement the selection union was written to stop, arriving through the failure path instead. Every id behind an artifact path is kept now, and a failure is recorded against all of them, for a failed import and a missing file alike. The second half is a fault in the fix from last round. The stand-in policy's matcher unions the two axes independently and the registry ANDs them, so guards scoped to (PreToolUse, Bash) and (PostToolUse, Write) also caught (PreToolUse, Write) — a cross product of scopes neither pack declared. Narrowing the matcher is not available: a policy that is never dispatched cannot decide anything. So the matcher stays a superset and the pairing is settled during evaluation, where the real event and tool are known. Both are covered end to end by tests that fail without them: the shared-artifact one allows the second pack's tool outright, and the cross-product one denies a pair no pack asked for.

High: Fail closed for partially registered shared artifacts
- Rule:
SEC-001 - Location:
src/hooks/handler.ts:457 - Evidence: Artifacts sharing a path are collapsed to one merged pack in custom-hooks-loader.ts (lines 482-530), so every loaded hook carries only the winner's pack ID. handler.ts records it only under that ID (lines 457-460). missingGuards then skips the other installed record when it has neither a load failure nor a registered entry (pack-failclosed.ts lines 189-193). If a shared artifact loads but omits a policy selected only by the non-winning record, that policy is neither registered nor represented by the synthetic deny. An isolated invocation of missingGuards with this state returned an empty guard list.
- Required change: Propagate the actual registered hook names to every original pack ID behind the shared artifact path, then add an end-to-end regression where a successfully imported shared artifact omits a policy selected only by the non-winning pack and verify its declared scope is denied.
The mirror of the last fix, on the path where nothing goes wrong. An artifact that imports FINE can still register less than its manifest declared — a publisher's catalog and their source drifting apart — and registration is recorded per pack id while a collapsed load hands back hooks carrying only the id the collapse kept. So a policy selected by the non-winning record and absent from the artifact left that pack in neither the failure map nor the registered map, and `missingGuards` skips a pack in neither. Nothing registered the policy and nothing denied on its behalf: the machine reported itself enforcing a scope that was running nothing. The loader now returns the ids sharing each artifact, and registrations are recorded against all of them, so the pack that selected the missing policy is measured against what actually loaded rather than against its neighbour. Read through an optional chain, because a caller that stubs the loader has no alias map and the honest reading of its absence is "this id only" — the same answer the map gives for an artifact only one pack resolved to.

4 participants
Policies leave the npm package and become packs — published as GitHub releases,
installed by digest, chosen by the person installing them rather than by us.
What a user does now
policy,packandpall still work — they translate topolicies, sonothing anyone has typed before breaks.
Setup stops choosing policies for you
The wizard's policy step is gone, and so is the larger offender behind it: the
opening "Recommended" path skipped that question entirely and installed
RECOMMENDED_POLICIES, fifteen hardcoded builtin names, on behalf of somebodywho had not seen the list. failproofai ships no policies of its own now — they
arrive as packs — so pre-ticking our set is a product decision taken for a
user who cannot yet evaluate it.
Whatever the scope already had is carried through untouched:
installHooksrunswith
replace: true, and passing anything less would switch off policies theuser turned on. Running setup twice must never reduce protection.
policy-presets.tsis deleted.customPoliciesEnabledis left alone in bothmodes rather than written from a checkbox that no longer exists — which also
closes the leak where finishing setup disabled every convention policy on disk.
Consequence, stated plainly: a fresh machine finishes setup with nothing
enforcing but
block-failproofai-commands, the compiled always-on guard. That isnow the intended state.
Three commands become one
Two of them were a single letter apart and did unrelated things.
policies addtakes either a policy name or a pack source, told apart by a slash — a policy
name matches
/^[A-Za-z0-9._-]+$/, so a slash is already illegal in one andunambiguous in the other. Same rule npm and docker use, and nobody has to
discover a flag before they can install somebody else's policies.
pack listwas two commands wearing one name — bare it described this machine,with an argument it described a pack somewhere else. Those are different
questions and they are different words now.
Installing shows you the list
policies addwith no argument used to answer "Missing policy name" and tell youto go read a list elsewhere and come back — the command telling the user to do
the work it exists for. The same objection applied to a bare
pack add, whichtook the publisher's defaults and only afterwards printed what it had decided: a
default is a suggestion, and a suggestion nobody saw is a decision taken on their
behalf.
One screen now, every policy grouped by pack and category, current state
pre-ticked, built on the
multiSelectthe wizard already uses rather than asecond picker.
Publishing is one command
Four before, two of which published nothing: installs read
releases/download/<tag>/<asset>and never touch the git tree, sogit initandgh repo createwere for humans reading the source. A publisher could only learnthat by reading
pack-store.ts.It goes over the GitHub REST API, not
gh release create— our ownblock-gh-pipelinebuiltin matches that exact command, and shipping a publishpath our own guardrail blocks is not a thing to do.
Two silent failures are refused: a tag that does not describe the manifest
version, and a private repository (which publishes to nobody —
pack addsendsno Authorization header at all, by design).
Help: 152 lines to 26
Every flag of every command was inlined on the index, so the thing you read to
find a command was the thing you read to use one, and the cost fell on the person
who knew least. One screen now, plus
failproofai help <command>— whichdispatches to
<command> --help, so there is exactly one copy of each and thetwo spellings cannot drift.
Three things that were documented nowhere reachable now are:
update --helpandmigrate --helpboth exited 1 with "Unexpected argument" becauseSUBCOMMANDSomitted them, and

already-installed pack keeps enforcing offline; only installing needs the
network.
Two things checked rather than assumed, because both would have been quiet
breakages:
id|version|sha256, so a machine that had the vendored copy and now has thefetched one only keys identically if the bytes match. They do —
9e63e6e2…both ways — so no existing user takes a cold rescan on upgrade.
registerFromVendoredPackalready returned
falsefor an absent directory and fell back to the compiledimplementations, its own comment naming "a tarball packed without it" as an
expected case.
The
fp-resetmigration deliberately does not fetch:resetHomeissynchronous and runs inside
failproofai update, and an upgrade that blocks ongithub.com — and fails when it is unreachable — is worse than one that finishes.
The carried names stay in config, which is what the no-pack fallback reads.
Three more fixes this turned up:
--policy, so everythird-party pack was told about
--categoryand--alland never abouttaking a single policy.
policies removepromised "re-adding it works offline", which stopped beingtrue.
failproofai update"to move them into the pack that ships with it" — bothhalves false now. It names
failproofai policies add core. Nothing had beenasserting on that string; a test does now.

Rebased on latest
main. Two failure sets on this branch are not from it,both verified rather than asserted:
dogfood-configs(8) fail only in a working tree where thoseskip-worktreeconfigs have been emptied locally; a clean clone at HEAD runs them 63/63.
python-version-pipeline(4) come frommain: both_version.pyfiles say0.0.1b2while the newest changelog section is0.0.1b1. This branch touchesno file under
sdk/orfp-cloud-cli/. The auto-bump commits that caused itcarry
[skip ci], which is why nothing caught it — it will now fail on everybranch cut from main until a
0.0.1b2section exists.Supply Chainis red for three chromadb advisories with no fixed version;re-running the previously green scan on unchanged code fails identically.
Update — choosing at install time, one linear setup, and a TUI pass
Installing a pack now asks instead of announcing.
policies add <source>took the publisher's
defaultEnabledflags and printed the result afterwards,which turns a recommendation into a decision made on the user's behalf — by
which point the policies are on their machine. A human who names no flags gets
the pack's list first, defaults pre-ticked, grouped by category. It reads the
MANIFEST only, so deciding about a stranger's pack still never downloads a
stranger's code. Flags and non-TTY skip it entirely.
Setup is one linear flow. The opening "Recommended or Customize?" is gone —
a question about the wizard rather than the machine, unanswerable until you know
the alternatives, which you learn by picking one. Recommended then took global
scope, the detected CLIs and fifteen unseen policies. Three questions remain, in
the order the machine needs them: the daemon (first, the only one needing a
password), which harnesses, and whether to connect. Scope is global always; the
harness step is now always asked rather than inferred.
The listing stopped contradicting itself. It said "not installed" directly
above an installed pack, because it was reporting whether HOOKS are wired — a
different question from whether policies exist, and one that hid the state that
actually matters: thirty-eight policies present and nothing calling failproofai
to run them. It reads
N on · NOT ENFORCINGnow.A TUI pass against the house guide, which found two things looking could not:
terminal may paint between them, so the cleared state is a real frame:
invisible locally, a blank flash per keypress over SSH or in tmux. One write
now, wrapped in synchronized output (
DECSET 2026).warning()wraps each element it is given, so the author's breaks became paragraph breaks
and wrapped again inside themselves — leaving "them." alone on a line at 60
columns.
⚠is also gone: the design system forbids emoji, and it takes emojipresentation on most terminals, which makes it two columns wide and silently
broke the hang-indent of the block it sat in. Section rules move to the brand's
heavy
━━, and❋becomes the real▮▮mark.Already met and worth not re-litigating: three colour tiers degrading to 16,
zero escapes in piped output, legible under
NO_COLOR, no colour-only meaning.One deliberate departure from the guide — it says refuse below a minimum
terminal size; that is right for a full-screen TUI and wrong for a CLI that
prints and exits, so this degrades instead, verified to 40 columns.

The 15 remaining failures are three pre-existing groups, none from this branch:
4 inherited from
main(both Python packages committed0.0.1b2with nochangelog section, via auto-bump commits carrying
[skip ci]), 8 local-onlydogfood-configsin a tree where thoseskip-worktreefiles were emptied, and3 in
fp-resetthat hang on the migration's spool flush — reproducible atcommitted HEAD with this work stashed, dependent on the machine having a real
daemon installed, which CI does not. That last group is not root-caused.
