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.

# 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.
- When runtime changes need a fresh sloptrap session to validate, ask sk4nz to restart you and give an exact prompt to 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.
- Capability-enabled runs are Podman-only. `packet-capture` uses a dedicated helper container/pod, and host-network capture must prompt for an explicit acknowledgement on every runtime launch.

@@ -130,26 +130,24 @@ The launcher executes targets sequentially, so `./sloptrap repo build run` perfo
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.
- `slopcap capture --interface <iface> [--filter <expr>] [--output <path>] [--stdout]` for non-promiscuous packet capture through a dedicated helper container. Host-network captures require an explicit acknowledgement each run.
## Execution Environment
- Container engine: Podman or Docker with identical command lines. Podman uses `--userns=keep-id`; Docker receives the equivalent `--user UID:GID` for standard runs.
- Container engine: Podman or Docker for standard runs. Capability-enabled runs require Podman. Podman uses `--userns=keep-id`; Docker receives the equivalent `--user UID:GID` for standard runs.
- Filesystem view: the project directory mounts at `/workspace`; `${HOME}/.codex/sloptrap/state/<project-hash>` mounts at `/codex`; `${HOME}/.codex/auth.json` mounts at `/codex/auth.json`.
- Ignore filter: `.sloptrapignore` entries are overlaid with tmpfs directories or empty bind mounts so data remains unavailable to Codex.
- Network: isolated networking is used by default; `allow_host_network=true` opts into `--network host`.
- Network: isolated networking is used by default; `allow_host_network=true` opts into `--network host`. When `packet-capture` is enabled, sloptrap starts a separate capture helper container in the same Podman pod so the main Codex container does not receive `NET_RAW`.
- Process context: standard runs drop capabilities, set `no-new-privileges`, use a read-only root filesystem, and keep scratch paths (`/tmp`, `/run`, `/run/lock`) on tmpfs. Capability-enabled runs may selectively add the runtime options required for the requested capability.
- Codex configuration: runtime flags are fixed to `--sandbox danger-full-access --ask-for-approval never`. Persistent Codex state is project-scoped under `${HOME}/.codex/sloptrap/state/`, while credentials are shared via `${HOME}/.codex/auth.json`.
- Codex configuration: runtime flags are fixed to `--sandbox danger-full-access --ask-for-approval never`. Persistent Codex state is project-scoped under `${HOME}/.codex/sloptrap/state/`, while credentials are shared via `${HOME}/.codex/auth.json` and mounted read-only except during the `login` target.
## Threat Model and Limits
- **Outbound disclosure**: prompts and referenced data travel from the container to the configured LLM endpoint. Any file content within `/workspace` or environment data exposed to the process can appear in that traffic.
- **Shared storage**: `/workspace`, project-scoped `/codex`, and `/codex/auth.json` are host mounts. Files written to these locations become visible on the host and to the LLM provider through prompts.
- **Environment surface**: the container receives a minimal fixed environment (HOME/XDG paths, `CODEX_HOME`). The manifest no longer allows injecting additional environment variables.
- **Process isolation**: standard runs keep a read-only root filesystem and no extra Linux capabilities. Capability-enabled runs deliberately relax specific runtime controls for the enabled feature, so they should be treated as a stronger trust decision than a default session.
- **Networking stance**: traffic is unrestricted once it leaves the container. sloptrap does not enforce an allowlist or DNS policy. Host networking is opt-in per manifest; if you require an offline or firewalled workflow, sloptrap is not an appropriate launcher.
- **Process isolation**: standard runs keep a read-only root filesystem and no extra Linux capabilities. Capability-enabled runs deliberately relax specific runtime controls for the enabled feature, so they should be treated as a stronger trust decision than a default session. `packet-capture` now runs in a dedicated helper container so the main Codex container does not hold raw-socket capability.
- **Networking stance**: traffic is unrestricted once it leaves the container. sloptrap does not enforce an allowlist or DNS policy. Host networking is opt-in per manifest; when it is combined with `packet-capture`, sloptrap warns and requires an explicit acknowledgement for each runtime launch because the capture helper will have raw packet access in the host namespace and may observe plaintext traffic or inject spoofed packets. If you require an offline or firewalled workflow, sloptrap is not an appropriate launcher.
- **Persistence**: Codex history and logs accumulate per project under `${HOME}/.codex/sloptrap/state/`. Sensitive prompts recorded on disk remain on the host after the session. Because `.git/` is ignored inside the container, any historical secrets in Git objects stay outside the LLM context unless explicitly surfaced in the working tree.
- **Codex cache hygiene**: per-project state mounts remain writable by the container and hold prompts/history/state, while `${HOME}/.codex/auth.json` holds shared credentials. Rotate credentials regularly and protect both locations.
- **Secret scanning**: sloptrap does not perform secret discovery or redaction; any credentials present in the project remain available to Codex and the upstream provider.
