 **No Python is bundled.** `pip`/`pipenv` themselves are not in the image (uv fetches its own Python; project runtimes live in child images).

Caveat: if your feed is fully locked down with no public upstream, `pipenv` itself must be mirrored there for `uvx` to fetch it.

 - **Exposed (per session):** your passed workspaces are read-write (unless `--ro`); host credentials when opted in — short-lived AWS SSO bearer tokens (`~/.aws/sso/cache`), the glab config token, `~/.terraform.d/credentials.tfrc.json`, and `GITLAB_TOKEN` / `TF_TOKEN_app_terraform_io` / `AWS_*` env vars are all readable inside the container; under `--gh-direct` (but **not** plain `--gh`, see [GitHub auth proxy](#github-auth-proxy)), the real `GH_TOKEN` is readable inside the container too; under `--registry`, the **full contents** of mounted `~/.npmrc` / `pip.conf` (and forwarded `*_TOKEN` / `UV_INDEX_*_PASSWORD` env) are readable — and those files can hold tokens for registries beyond the one you intended (`~/.netrc` is deliberately not mounted, see [Private package registries](#private-package-registries)); full outbound network with no egress filtering.
 - **GitHub via the proxy (`--gh`):** the real token itself no longer reaches the agent container — the biggest prior exposure for this flag is gone. What remains is _live capability_: a compromised session can still act on GitHub through the sidecar for the life of the session, bounded by its policy (default: no repo deletion, extensible via `OPENCODE_DOCKER_GH_POLICY`) and recorded in its audit log if you capture it (`docker logs <sidecar-name>`) before teardown. The sidecar is a policy point and a record, not a guarantee that a compromised session can't act on GitHub at all.
 - **Exposed (cross-session):** the persistent `opencode-root` and `opencode-home` named volumes hold the OpenCode OAuth token, in-container `gh` / `glab` / `terraform login` state, shell history, and conversation history. `opencode --resume` can replay sessions from **any** past workspace — see [Resuming sessions across workspaces](#resuming-sessions-across-workspaces). Skipped under `--ephemeral`.
-- **Runtime code-fetch:** `npx`, `pnpm dlx`, `uvx`, and `tfenv install` fetch and execute arbitrary code from public sources on first use — npm and PyPI for the package managers, `releases.hashicorp.com` for `tfenv install`. Under `--auto`, a prompt-injected workspace can trigger these. `pnpm dlx` adds zero marginal blast radius vs the already-reachable `npx`; `uvx` is a _new_ PyPI execution primitive (no Python runtime existed in the image before); `tfenv install` is a _new_ HashiCorp release-channel execution primitive whose downloaded `terraform` binary is intentionally **not** sha256-pinned in the image (versions are project-pinned via `.terraform-version`, so the image stays neutral on version policy). Build-time installs of the CLIs themselves are pinned by version + sha256 where the ecosystem supports it (uv binary, glab .deb, AWS CLI, tfenv source archive), and by version only for npm-backed packages (opencode-ai, openspec, pnpm) — `--ignore-scripts` blocks lifecycle scripts at install time but does not protect against a compromised registry serving a malicious tarball at the pinned version.

 - **Private registries (`--registry`):** this _narrows_ where the package managers resolve packages — pointing `uv` / `pnpm` / pip at a curated private feed instead of public npm/PyPI — which can reduce dependency-confusion exposure, but only as much as your host config and the feed's upstream setup dictate. It is registry-resolution config, **not** network egress filtering: `npx`, `git+https` installs, `curl`, and every other egress path are unaffected, and `--auto` runtime code-fetch (above) still reaches whatever the resolved feed serves. Treat it as supply-chain hygiene, not a network boundary.
 - **If a session is compromised:** assume exfiltration already happened (full network egress). Then: rotate the host sessions for every flag that was passed — `glab auth login`, `aws sso login`, `terraform login`; under `--registry`, re-run `aws codeartifact login` / rotate the npm·PyPI registry tokens exposed via the mounted `~/.npmrc` / `pip.conf`. **GitHub is different under `--gh`:** the real token never entered the container, so there's no token to rotate on that basis alone — but review what the session _did_ through the proxy during its lifetime (the sidecar's audit log helps, if you captured it via `docker logs` before teardown), and revert any resulting GitHub-side actions. If the token itself may be exposed (a `--gh-direct` session, a version predating this proxy, or any doubt), **revoke** it — not merely `gh auth logout`/`login`, which only clear local state and leave the issued token valid at GitHub: revoke the _GitHub CLI_ authorization under _Settings → Applications → Authorized OAuth Apps_, or delete the PAT under _Settings → Developer settings_ if you used one. In all cases: revoke the OpenCode OAuth credential, and clear the named volumes (`docker volume rm opencode-root opencode-home`) to flush in-container auth state and cross-workspace conversation history that `opencode --resume` could otherwise replay.

 ## Updating pinned tool versions
 
-`uv`, `glab`, `aws-cli`, and `tfenv` are downloaded directly from GitHub/GitLab/vendor sites rather than from a language package registry, so nothing else verifies the bytes. Each is pinned to a version **and** a per-architecture sha256 that the Dockerfile checks (`sha256sum -c`) before installing. The npm-installed tools (`opencode-ai`, `openspec`, `pnpm`) are pinned by version only — `npm install` already verifies the tarball against the registry's `dist.integrity`, and CI additionally runs `npm audit signatures`.

 The pins live in version-controlled fragments under [`pins/`](pins/), one `pins/<tool>.env` per tool, which the Dockerfile `COPY`s and sources at build time — so `docker build` is reproducible from the committed files.
