Content goes in as data, not as a system instruction. - `UNTRUSTED_CONTEXT_POLICY` is a system-prompt preamble that states the same policy at the top of every session where untrusted data may appear. **Untrusted surfaces that must go through this wrapper:** web search results, fetched URLs, emails (read), saved memories, skill text, notes, and any tool output sourced from outside the server. Injecting untrusted content directly into the system role is a security bug. +The thread maintains monotonic `external`, `workspace`, `Odysseus`, and `private` observations in the database. Switching models, starting a later turn, teacher takeover, reloading the browser, or forking the conversation cannot clear them. Agent mode does not ambiently retrieve saved memories or personal-document RAG; private reads occur through explicit tool calls and their results are provenance-labelled before later actions. Directly opened documents, emails, and uploads are explicit selections and are labelled before the model sees them. + +### Agent Run Authority + +Model output requests an action; it does not authorize one. `src/tool_capabilities.py` classifies each built-in tool's effects and result integrity, while `src/agent_run_policy.py` combines those fixed classifications with the thread's server-owned security mode. The temporary blanket gate that armed after any untrusted tool result is disabled; mode-owned authority checks remain active. + +- **Sandbox (default):** process execution stays inside the workspace sandbox. Brokered public reads, private/workspace operations, and contained execution can continue without a new approval merely because earlier context was untrusted. Unknown tools, arbitrary network egress, external side effects, admin changes, and destructive actions still require an exact approval. +- **Full access:** an admin or intentional single-user deployment may explicitly opt into direct execution with that user's normal OS permissions.

A successful prompt-injection reaching a shell-enabled admin session can make outbound requests to internal services. See #1058 for the sandbox proposal. +1. **Linux sandbox portability and explicit Full Access.** Agent `bash`, Python, tmux, and detached background commands default to a Bubblewrap profile with a private network namespace, cleared environment, private temp/home, one writable workspace, credential-path overlays, read-only `.git` metadata, and generous per-process rlimits. Internet-enabled process execution is limited to the trusted HTTP(S) egress broker; raw container networking is never shared with either mode. Odysseus performs the actual capability probes under the service user before process execution. A failed probe blocks only process tools and never downgrades automatically. An administrator may temporarily enable **Full Access** only after a warning plus typed confirmation. Full Access grants the process the Odysseus operating-system user's filesystem view while retaining the sandbox's private PID/network policy; an already-running Full Access process retains its launch-time authority until it exits or is killed. The process boundary mounts a fresh procfs scoped to its private PID namespace. Hard workspace-disk quotas and aggregate agent-pool/per-instance CPU, memory, and PID ceilings are not established in this slice; current limits are per process and the aggregate design is tracked separately. 2. **SSRF via `/api/v1/chat` `base_url` parameter.** A chat-scoped API token can supply an arbitrary `base_url`; the server forwards the LLM request to that host without validating the scheme or address.
