Harden launcher overrides and fix opencode backend regressions

- remove codex auth mounts from opencode run/shell paths
  - reject opencode login and invalid backend values
  - harden opencode config writes against symlink clobbering
  - fix opencode build args and packages_extra handling
  - enforce cap-drop and read-only rootfs in runtime commands
  - reject dangerous runtime/build env overrides
  - update README and test docs to match actual behavior
  - extend regression coverage for backend safety and hardening

 - 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.

 ## How It Works
 
-- The project directory mounts at `/workspace`; project-scoped Codex state mounts at `/codex` from `${HOME}/.codex/sloptrap/state/<project-hash>`, and shared auth mounts from `${HOME}/.codex/auth.json` to `/codex/auth.json`.
+- The project directory mounts at `/workspace`; project-scoped state mounts at `/codex` from `${HOME}/.codex/sloptrap/state/<project-hash>`. Codex also mounts shared auth from `${HOME}/.codex/auth.json` to `/codex/auth.json`; opencode does not.
 - `.sloptrapignore` entries (if present in your project) are overlaid by tmpfs (for directories) or empty bind mounts (for files) so Codex cannot read the masked content.
 - sloptrap launches containers on an isolated network (`bridge` on Docker, `slirp4netns` on Podman) with `--cap-drop=ALL`, `--security-opt no-new-privileges`, a read-only root filesystem, and tmpfs-backed `/tmp`, `/run`, and `/run/lock`. Projects that explicitly set `allow_host_network=true` in their manifest opt into `--network host`.
-- The helper Dockerfile is embedded inside `sloptrap`; set `SLOPTRAP_DOCKERFILE_PATH=/path/to/custom/Dockerfile` if you need to supply your own recipe. The default image installs `curl`, `bash`, `ca-certificates`, `libstdc++6`, `git`, `ripgrep`, `xxd`, and `file`, so most debugging helpers are already available without adding `packages_extra`.

-Capability trust is local state, not part of the repository. Builds for manifests that request capabilities require either an interactive trust confirmation or `--trust-capabilities`.

The `allow_host_network=true` plus `packet-capture` combination still requires a separate interactive acknowledgement each time a runtime container is launched.
+### AI Backends
+
+**Codex** (default): Uses OpenAI Codex CLI with state stored in `~/.codex/`. Supports login mode for credential sharing.
+
+**opencode**: Uses Anomaly opencode CLI with project-scoped state and config stored under sloptrap's per-project state directory. sloptrap downloads the latest Linux CLI release artifact from Anomaly during image builds, verifies its digest from the GitHub release metadata, and copies it into the container image. Connects to any OpenAI-compatible inference server (llama.cpp, Ollama, vLLM, etc.). When `opencode_server` points at `localhost` under isolated networking, sloptrap rewrites it to `http://sloptrap.host:...` so host-local model servers remain reachable from inside the container. No Codex auth file is mounted for opencode sessions.

-### Capability Helpers
-
-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 non-promiscuous packet capture through a dedicated helper container. Host-network captures require an explicit acknowledgement each run.

 ## 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.
+- **Shared storage**: `/workspace` and project-scoped `/codex` are host mounts. For Codex, `/codex/auth.json` is also mounted from the host; opencode sessions do not receive that shared credential file. Files written to mounted locations become visible on the host and may be surfaced to the configured 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. `packet-capture` now runs in a dedicated helper container so the main Codex container does not hold raw-socket capability.
+- **Process isolation**: standard runs keep a read-only root filesystem and no extra Linux capabilities.
-- **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.
+- **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.
 - **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.
+- **Codex cache hygiene**: per-project state mounts remain writable by the container and hold prompts/history/state, while `${HOME}/.codex/auth.json` holds shared Codex credentials when that backend is used. 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.
 - **Local model exception**: pointing Codex at a local or self-hosted model keeps data within the host network boundary, but the filesystem and environment exposure described above is unchanged.
