+# skz-sloptrap
+
+This workspace is the source code of `sloptrap`, eg. your own runtime.
+Your author, 'sk4nz', has ran the command `sloptrap path/to/skz-sloptrap` and you are living in your own reflection.
+
+# Recursive `slopsloptrap`
+
+sloptrap can recurse.
+
+If you need to prove it, spawn a child from this repo with sloptrap:
+
+`./sloptrap /workspace ...`
+
+This starts a child `slopsloptrap`. Use the child normally, as the end-user would.
+
+# Keep Memory
+
+Future sloptrap instances should add short, useful, durable notes they learn during their session to this file.
+
+Only add high-signal information that is likely to help later runs.
+Keep additions brief.
+Do not remove existing instructions unless they are outdated or wrong.
+
+---
+# Session Memory
+
+- When you make changes that affect how the runtime behaves and cannot test it with recursion, you can ask sk4nz to restart you.
+- If recursion is blocked by the current session state and a restart is required, give sk4nz an exact prompt to paste into the next restarted session so it can continue from the current checkpoint.
+- Useful checks in the skz-sloptrap repo:
+  `shellcheck sloptrap`
+  `bash tests/run_tests.sh` (you can also run them separately)
+- Recursive nested-podman inside an already user-namespaced sloptrap needs subuid/subgid ranges derived from `/proc/self/uid_map` and `/proc/self/gid_map`; hardcoding `100000:65536` breaks `newuidmap`.
+- When running tests from inside sloptrap, inherited `CODEX_HOME=/codex` plus `SLOPTRAP_PREFER_CODEX_HOME=1` can leak into host-style child launches; ignore that preference when `HOME` has been redirected elsewhere and the runtime hints still point into the inherited `/codex` tree.
+- For real recursive `./sloptrap` launches, correct `/proc/self/uid_map` alone is not enough: if the current session still has stale read-only `/etc/subuid` and `/etc/subgid` mounts (for example `sk4nz:100000:65536`), the first nested podman launch still fails before child startup.
+- Forcing `SLOPTRAP_CONTAINER_ENGINE=sloppodman` inside sloptrap also needs `TMPDIR` under `/workspace`; otherwise its build-context path guard rejects the staged Dockerfile under `/tmp` before you reach the real subuid/subgid problem.
+- If a restarted session still inherits stale read-only `/etc/subuid` and `/etc/subgid` tmpfs mounts, an unprivileged agent cannot repair them in-place (`umount` says `must be superuser to unmount`); both podman and sloppodman stay blocked until the session starts without those mounts.
+- Outer sloptrap launches no longer need `/etc/subuid` or `/etc/subgid` bind mounts: `nested-podman` now disables read-only rootfs and the container entrypoint synthesizes container-local subid files from `/proc/self/{uid,gid}_map` before dropping privileges.
+- Even without stale `/etc/subuid` mounts, recursion still fails if the container-local subid files name `sloptrap` instead of the real dropped user (`sk4nz` here): `podman info --debug` warns `no subuid ranges found for user "sk4nz"` and the first inner build dies in `newuidmap ... write to uid_map failed: Operation not permitted`.
+- In this Debian 13 / podman 5.4.2 environment, exporting `_CONTAINERS_USERNS_CONFIGURED=done` for nested podman moves the failure past `newuidmap`, but the next blockers are inside Buildah: with `BUILDAH_ISOLATION=chroot`, recursive builds fail `cannot set --network other than host with --isolation chroot`; without chroot, `podman build` can segfault in `network.defaultNetworkBackend`.
+- Recursive preload now has a host-side path: the outer launcher saves `$SLOPTRAP_IMAGE_NAME` into capability state and mounts it into the container as `SLOPTRAP_RECURSIVE_PARENT_IMAGE_ARCHIVE=/codex/capabilities/podman/preload/<image>.tar`, and child `build-if-missing` tries `sloppodman load -i` before any inner build. A pre-existing session must be restarted to test that path because it cannot add the new preload mount/env to itself after startup.
+- With stale subid mounts gone, recursive `./sloptrap /workspace` can still fail earlier during the inner image build: `crun` tries to open `/proc/sys/net/ipv4/ping_group_range` and gets `Read-only file system` while creating the build container.
+- In a fragile nested-podman session, `podman system migrate` can make things worse: a state that still answered `podman info` fell back to repeated `newuidmap ... write to uid_map failed: Operation not permitted` failures afterward.

+When the current manifest's capabilities are trusted and enabled, the container includes helper commands:
 
 - `slop-apt install <package...>` for session-scoped package installation.
 - `slopcap capture --interface <iface> [--filter <expr>] [--output <path>] [--stdout]` for packet capture.
 - `sloppodman <pull|build|tag|run|ps|logs|stop|rm|inspect> ...` for nested Podman workflows. `build` contexts and Dockerfiles must remain inside `/workspace`, and pushes are not supported.
+- When `nested-podman` is enabled, sloptrap makes the container root filesystem writable long enough to synthesize container-local `/etc/subuid` and `/etc/subgid` files from the live namespace maps, so rootless nested Podman does not depend on host subid files.
