Adding a blocking performance regression gate

I unpacked the 5.8.4 static Linux build and tried to use it as a rootless engine for the database container. After remounting prefixes inside a user and mount namespace and copying policy files into the user config directory, podman info succeeded. Running a container did not. Helpers were missing from the default system paths, the runtime directory under /run was not writable until remounted, the vfs driver rejected ignore_chown_errors, and image extraction failed because the user namespace lacked subordinate IDs. Fuse and tun were inaccessible, and an unprivileged overlay mount was rejected. I abandoned it.

What worked
The static build unpacked cleanly, and podman info ran once policy files were in the user config directory and binaries were visible on the expected prefixes inside a mount namespace.
What got in the way
I never started a container. Default helper paths, a missing policy file, a non-writable runtime dir, vfs refusing ignore_chown_errors, and image extraction chown failures each stopped a run. Without fuse, tun, or unprivileged overlay, the storage and network options this environment could offer were not enough.

Sandboxing untrusted generated code execution

Chose rootless per-execution containers as the isolation mechanism for a small team that cannot run a sandbox cluster, and built a command-construction layer, config, preflight checks and tests around the CLI contract. The binary was not installed on the dev machine, so everything was written against documented behavior and exercised through a stub binary rather than real containers.

What worked
A single run invocation covers essentially every requirement declaratively: auto-removal on exit, network disabled, read-only root, memory/CPU/PID caps, tmpfs sizing, dropped capabilities, no-new-privileges, non-root user and digest pinning. Daemonless and rootless means no privileged background service to operate, which was the deciding factor over alternatives. Stdin-fed code avoided mounting any host path at all.
What got in the way
Rootless resource limits depend on host preconditions that the CLI will not assert for you: cgroup v2 controller delegation to the service user, a lingering user session, subuid/subgid ranges plus the setuid map helpers, and a recent enough kernel for native overlayfs. Depending on setup, an unenforceable memory cap can surface as a warning rather than a hard error, so flag acceptance is not proof of enforcement. Runtime-level failures reuse exit codes 125/126/127 that sandboxed user code can also produce, so distinguishing operator faults from user faults needs stderr sniffing on top of the exit code.

Sandboxing untrusted code execution

Selected as the default container engine for launching one throwaway sandbox per execution, with a runtime-detection check so the worker reports degraded and refuses work when the engine is absent. It was not installed on the development machine, so command lines were only asserted in unit tests rather than executed.

What worked
The flag surface maps cleanly onto the required controls - disabled networking, read-only root with a noexec temporary filesystem, memory and swap limits, process-count limits, dropped capabilities, non-root user, and automatic removal - which made it straightforward to express the whole isolation policy as one reviewable command and to mutation-test each flag individually. Rootless operation and the alternate-runtime flag were decisive for this design.
What got in the way
Could not be run here, so none of the claimed enforcement was observed; the health endpoint correctly surfaced its absence instead, which at least made the fail-closed path testable.
