The CLI no longer asks the 16 built-in semantic checks on its own. They
ship in FailproofAI/jev-policies and are asked only where that pack is
installed; `SEMANTIC_POLICIES` stays in the source as data (the
reserved-name list, the pack's definition, and the budget reserve).
- semanticPoliciesFromPacks / resolveSemanticPolicies: empty with no
declaring pack (never a compiled-in fallback); a FailproofAI pack's
checks fill the reserved names, third-party checks sit beside them.
- effectiveReviewerNames / reviewerNamesFor: only what packs declare, so
a reviewable policy naming an unsupplied check resolves hard.
- handler: Jev is idle with no pack check (jevChecksAvailable) — no
config load, no review, no intent capture, no per-policy authority
warnings: byte-identical to unconfigured (golden extended).
- budget: FailproofAI packs get the whole request and spend first; a
third party gets what is left at load time, and is held at publish to
THIRD_PARTY_QUESTION_CHARS (what jev-policies leaves).
- jev status / setup / config connect / dashboard panel print one line
naming `policies add FailproofAI/jev-policies` when Jev is on and idle;
`jev status --json` carries `jevChecks {installed, names, idle, fix}`.
- tests: a jev-policies pack fixture; decision tests install it.

authority, jev-byok, jev-cloud, publish-a-pack and the CLI reference now say Jev's checks come only from installed packs, that FailproofAI's sixteen ship in FailproofAI/jev-policies, and that Jev is idle without one. CHANGELOG gains a 1.0.9-beta.0 section. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Installing any pack stopped `enabledPolicies` from registering, so the hint every Jev surface now prints (install FailproofAI/jev-policies, a pack with no regex policies) would have switched off block-rm-rf, block-sudo and the rest. hasRegexPacks() (pack-manifest) is the migration shim's test now: only a pack that carries regex policies replaces the builtins. Applied in the handler, the reviewability survey (so `jev status` counts the 15 reviewable builtins with jev-policies alone), `policies --install`, the `policies` listing footer and the audit's closing hint.

…e enabledPolicies is on With no regex pack installed, the handler registers the built-ins named in enabledPolicies, so the onboarding audit's closing line was wrong for exactly those machines. It now appears only when no regex pack is installed and no built-in policy is enabled.

Jev's checks now come only from installed packs. The 16 checks that shipped built into 1.0.8 (
destructive-deletion,credential-exfiltration,external-destructive-action, …) are no longer asked unless a pack supplies them. They ship inFailproofAI/jev-policies, which already carries all 16.Why
In 1.0.8, turning Jev on (for example
config --tokenwith a machine key, then enforce) activated all 16 built-in checks at once, with no pack installed. On a live machine that meant unexpected Jev denies, e.g.external-destructive-actionblocking MCP payment calls. Checks should be opted into like any other policy: by installing the pack.Behaviour
