 Separate from the registry, every job is also mirrored to a durable append-only
 audit log at `.mam/delegate_job_logs/<job_id>/` (override with
-`DELEGATE_JOB_LOGS_DIR`, default `<cwd>/.mam/delegate_job_logs`). The registry
+`DELEGATE_JOB_LOGS_DIR`, an audit-log root that is **not** next to the
+registry; default: the `delegate_job_logs` next to the registry in use). The registry
 is **live state** mutated in place; the audit log is **history** that survives
 even after the registry dir is cleaned up. It is git-ignored.
