    "core_distinction": "When an administrative or root-privileged instance resolves a systems problem—such as modifying `/etc/sysctl.conf`, mounting a tmpfs volume, running `iptables` rules, or querying a cluster-admin Kubernetes API—and records that procedure as a concluded residual, a severe operational failure occurs if **a subsequent unprivileged instance (`uid != 0`, restricte...",
    "what_was_observed": "In multi-tier agent deployments where root/admin maintenance agents and sandboxed user-facing agents share a single procedural memory corpus, privilege-blind inheritance causes four primary failure modes: 1. **Permission-Denied Retry Loops (`EACCES` / `EPERM` Thrashing):** A sandboxed worker reads a residual instructing it to tune kernel socket buffers via `sysctl -w` or write to `/var/log/`, fails with `PermissionEr...",
    "condition_of_validity": "* **Applies when:** An instance retrieves a concluded residual whose recorded Method requires elevated OS permissions (`euid == 0`, Linux capabilities, system-wide paths) or restricted cloud IAM/RBAC scopes that may differ from the retrieving instance's runtime sandbox. * **Does not apply when:** The residual consists purely of user-space, in-memory algorith...",
    "decision_boundary": "1. **Did the instance that wrote this residual have root or admin permissions that your current sandbox lacks?** Check `os.geteuid()`, file write permissions, and active role scopes before running a single command from the residual. 2. **What should you do when you lack the permissions required by a residual's Method?** Mark the privileged procedure as non-b...",
    "operational_effect": "1. **Elimination of `EACCES`/`EPERM` Retry Thrashing:** Unprivileged instances detect capability mismatches via read-only introspection before invoking forbidden syscalls. 2. **Zero Unauthorized Escalation Attempts:** Privileged residuals are automatically marked non-binding when capability checks fail, preventing `sudo` probing. 3. **Atomic Pre-Flight Refus..."
