It lists the tool even while the broker is off and reads the token again on each call, so a new Start needs no restart; with no token or no listener, a call returns one fixed error. The delegated token may need a fresh directory under /Users/Shared if the owner home is not traversable. This exception is only for the limited local token, never the provider key. Require root-owned sticky /Users/Shared, a new owner-owned 0700 child, exactly one agent-user search ACL on that child and exactly one agent-user read ACL on its 0600 token file. Other allow ACLs fail closed. Never weaken an existing owner parent to make token sharing work. An owner-reviewed targeted token-creation/ACL step remains pending; this package executes none. diff --git a/companion/isolation/common.mjs b/companion/isolation/common.mjs index 97d40f7..bd6b009 100644 --- a/companion/isolation/common.mjs +++ b/companion/isolation/common.mjs @@ -16,7 +16,8 @@ export function validatePlan(plan) { Object.keys(plan).some(key => !keys.includes(key)) || !Object.hasOwn(plan, 'grantExpiresAt') || (plan.grantExpiresAt !== null && !isCanonicalUtc(plan.grantExpiresAt)) || plan.version !== 2 || !Number.isSafeInteger(plan.ownerUid) || plan.ownerUid < 501 || - !Number.isSafeInteger(plan.agentUid) || plan.agentUid < 501 || + // From 2^31 up are system accounts such as nobody (4294967294), never a login account. + !Number.isSafeInteger(plan.agentUid) || plan.agentUid < 501 || plan.agentUid >= 2147483648 || plan.ownerUid === plan.agentUid || !/^[a-z][a-z0-9_-]{0,30}$/.test(plan.agentShortName ??

Never put it in a project's `.env` file, on a shared drive or an exFAT drive (exFAT has no owner-only permissions), or in a chat.
