+# Run Interaction Policy
+
+The harness resolves a `RunInteractionPolicy` from the run context and uses it
+as the single source for lead-agent tool visibility, clarification middleware
+behavior, sandbox network approval eligibility, and system-prompt guidance.
+The implementation lives in `deerflow/agents/interaction_policy.py`.
+
+## Modes and precedence
+
+Interactive runs may ask a human for clarification. Runs in `scheduled`,
+`webhook`, or `autonomous` mode must use the available context, make minimal
+reversible assumptions, list material assumptions, or return a structured
+`BLOCKED` result naming the missing decision for high-risk or irreversible
+work without sufficient authorization. They must never wait for a synchronous
+human response. Suppressed clarification tool results must preserve this same
+boundary, not tell the model to unconditionally carry out an ambiguous action.
+
+An explicit `interaction_mode` takes precedence over legacy context hints.
+An unknown explicit mode is a configuration error, never an interactive fallback.
+Without an explicit mode, the resolver checks `non_interactive` (scheduled),
+then `channel_name="github"` (webhook), then `disable_clarification`
+(autonomous); otherwise it selects interactive. These legacy flags remain
+supported while entry points migrate to explicit modes.
+
+Sync and async sandbox network approval paths use the same resolved policy.
+Unattended runs deny pending network requests without opening a Human Input
+card. Subagents always deny pending requests, even in an interactive run.
+
+## Gateway trust boundary
+
+`interaction_mode`, `non_interactive`, `disable_clarification`, and
+`channel_name` are internal-caller-only Gateway context keys. The latter two
+remain runtime-only and are never copied into checkpoint-persisted
+`configurable`. Public run requests cannot use these keys to disable
+clarification, impersonate a webhook channel, or override a scheduled run back
+to interactive behavior.

+
+**CRITICAL RULE: Clarification ALWAYS comes BEFORE action. Never start working and clarify mid-execution.**
+
+**MANDATORY Clarification Scenarios - You MUST call ask_clarification BEFORE starting work when:**
+
+1. **Missing Information** (`missing_info`): Required details not provided
+   - Example: User says "create a web scraper" but doesn't specify the target website
+   - Example: "Deploy the app" without specifying environment
+   - **REQUIRED ACTION**: Call ask_clarification to get the missing information
+
+2. **Ambiguous Requirements** (`ambiguous_requirement`): Multiple valid interpretations exist
+   - Example: "Optimize the code" could mean performance, readability, or memory usage
+   - Example: "Make it better" is unclear what aspect to improve
+   - **REQUIRED ACTION**: Call ask_clarification to clarify the exact requirement
+
+3. **Approach Choices** (`approach_choice`): Several valid approaches exist

+   - Example: "Store data" could use database, files, cache, etc.
+   - **REQUIRED ACTION**: Call ask_clarification to let user choose the approach
+
+4. **Risky Operations** (`risk_confirmation`): Destructive actions need confirmation

+   - Example: Overwriting existing code or data
+   - **REQUIRED ACTION**: Call ask_clarification to get explicit confirmation
+
+5. **Suggestions** (`suggestion`): You have a recommendation but want approval
+   - Example: "I recommend refactoring this code. Should I proceed?"
+   - **REQUIRED ACTION**: Call ask_clarification to get approval
+
+**STRICT ENFORCEMENT:**
+- ❌ DO NOT start working and then ask for clarification mid-execution - clarify FIRST
+- ❌ DO NOT skip clarification for "efficiency" - accuracy matters more than speed
+- ❌ DO NOT make assumptions when information is missing - ALWAYS ask
+- ❌ DO NOT proceed with guesses - STOP and call ask_clarification first
+- ❌ DO NOT call any other tool in the same turn as ask_clarification — sibling calls are dropped
+- ✅ Analyze the request in thinking → Identify unclear aspects → Ask BEFORE any action
+- ✅ If you identify the need for clarification in your thinking, you MUST call the tool IMMEDIATELY
+- ✅ After calling ask_clarification, execution will be interrupted automatically
+- ✅ Wait for user response - do NOT continue with assumptions

+    context="Why you need this information",  # optional but recommended
+    options=["option1", "option2"]  # optional, for choices
+)
+```
+
+**Example:**
+User: "Deploy the application"
+You (thinking): Missing environment info - I MUST ask for clarification
+You (action): ask_clarification(
+    question="Which environment should I deploy to?",
+    clarification_type="approach_choice",
+    context="I need to know the target environment for proper configuration",

-   - **REQUIRED ACTION**: Call ask_clarification to clarify the exact requirement
-
-3. **Approach Choices** (`approach_choice`): Several valid approaches exist
-   - Example: "Add authentication" could use JWT, OAuth, session-based, or API keys
-   - Example: "Store data" could use database, files, cache, etc.
-   - **REQUIRED ACTION**: Call ask_clarification to let user choose the approach
-
-4. **Risky Operations** (`risk_confirmation`): Destructive actions need confirmation
-   - Example: Deleting files, modifying production configs, database operations
-   - Example: Overwriting existing code or data
-   - **REQUIRED ACTION**: Call ask_clarification to get explicit confirmation
-
-5. **Suggestions** (`suggestion`): You have a recommendation but want approval
-   - Example: "I recommend refactoring this code. Should I proceed?"
-   - **REQUIRED ACTION**: Call ask_clarification to get approval
-
-**STRICT ENFORCEMENT:**
-- ❌ DO NOT start working and then ask for clarification mid-execution - clarify FIRST
-- ❌ DO NOT skip clarification for "efficiency" - accuracy matters more than speed
-- ❌ DO NOT make assumptions when information is missing - ALWAYS ask
-- ❌ DO NOT proceed with guesses - STOP and call ask_clarification first
-- ❌ DO NOT call any other tool in the same turn as ask_clarification — sibling calls are dropped
-- ✅ Analyze the request in thinking → Identify unclear aspects → Ask BEFORE any action
-- ✅ If you identify the need for clarification in your thinking, you MUST call the tool IMMEDIATELY
-- ✅ After calling ask_clarification, execution will be interrupted automatically
-- ✅ Wait for user response - do NOT continue with assumptions
-
-**How to Use:**
-```python
-ask_clarification(
-    question="Your specific question here?",
-    clarification_type="missing_info",  # or other type
-    context="Why you need this information",  # optional but recommended
-    options=["option1", "option2"]  # optional, for choices
-)
-```
-
-**Example:**
-User: "Deploy the application"
-You (thinking): Missing environment info - I MUST ask for clarification
-You (action): ask_clarification(
-    question="Which environment should I deploy to?",
-    clarification_type="approach_choice",
-    context="I need to know the target environment for proper configuration",
-    options=["development", "staging", "production"]
-)
-[Execution stops - wait for user response]
-
-User: "staging"
-You: "Deploying to staging..." [proceed]

 ### Sandbox System (`packages/harness/deerflow/sandbox/`)
 
+**Network approval interaction policy**: Sync and async `SandboxMiddleware` tool
+wrappers use `resolve_run_interaction_policy()` to decide whether a lead run can
+open a network approval card. Explicit `autonomous`, `webhook`, and `scheduled`
+modes auto-deny pending requests, as do the legacy unattended flags and GitHub
+channel fallback. An explicit `interactive` mode takes precedence over those
+legacy hints. Subagents always auto-deny, including in interactive runs; never
+consume events into a human-input card when no human can respond.
+
 **Interface**: `Sandbox`: `execute_command(command, env=None)`, additive `execute_command_in_scope(..., scope_id=...)` / `release_command_scope(scope_id)`, `read_file`, `write_file`, `list_dir`, `glob`, `grep`. Scoped hooks default to pass-through without server-side sessions, preserving third-party subclasses. `grep` accepts a text file or directory tree. Per-call `env` injects secrets: `LocalSandbox` merges into the subprocess environment; `AioSandbox` uses fresh `bash.exec(env=...)` sessions. `list_dir`: missing path → `FileNotFoundError`; command/client failure → `OSError`, never `[]` (`ls_tool`: `(empty)`). Remote `glob`/`grep` share it via `sandbox/remote_search.py`: missing root → `FileNotFoundError`, failed search → `OSError`; only a genuine no-match returns `[]`. The parser takes the command's `limit` and reports `truncated` when output passed it, which providers return after Python-side filtering; tools call an empty truncated result incomplete. Remote `grep(glob=...)` scopes like `glob()` (root-relative `path_matches`), never by basename alone. Remotes use `sandbox/remote_list_dir.py`: capture `find`'s status, not `| head`'s (`sh -lc` lacks `pipefail`); missing binary → `OSError`; truncation SIGPIPE → success.
 **Provider Pattern**: `SandboxProvider` exposes `acquire`, `acquire_async`, `get`, `release`. Async agent/tool paths use async hooks to keep Docker creation, discovery, cross-process locking, readiness polling, and release off-loop. Set `supports_agent_skill_isolation=True` only when the whole tool surface enforces explicit lead Agent policy: bind mounts use prepared thread roots; upload providers implement `sync_agent_skills`. Host-backed providers report false if an enabled shell bypasses path mappings. Under explicit policy, middleware rejects unsupported providers before acquire.
 **Shared components** (RFC #4741): remote IDs use `derive_sandbox_scope_token` (`sandbox/identity.py`); preserve its keyword-only SHA-256/16-hex contract to avoid orphaning containers. `AcquireSerializer` (`sandbox/acquire_serialization.py`) serializes selected acquire/release transitions with a bounded, refcounted per-key `threading.Lock` table and dedicated bounded executor (no event-loop/default-executor blocking). Workers own cancellation cleanup without waiting for cancelled tasks to resume; provider `shutdown()`/`reset()` calls idempotent `close()`. Keys: AIO `(user_id, thread_id)`, E2B `(user_id, thread_id, skills_root)`, BoxLite/Tenki/OpenSandbox derived id. Random-UUID `thread_id=None` acquires bypass serialization.

 The ordinary `task` boundary carries one narrow parent-loop middleware recorder into the isolated subagent runtime under separate loop-detection, tool-promotion, and tool-progress keys. It schedules only `record_middleware` calls back onto the loop that owns `RunJournal`, keeps an execution-local atomic promotion claim so parallel searches do not double-report one new schema, is fenced and drained once before `task` returns, and never exposes the journal or event store to the child loop. Durable batch tasks have no parent run journal and do not use this bridge.
 
 Scheduled-task runtime note:
-- Scheduled background runs set `context.non_interactive=true` and therefore exclude `ask_clarification` from the lead-agent tool list. This keeps scheduler-triggered runs from stalling on human confirmation mid-execution. `non_interactive` is an internal-only context key: it is merged from `body.context` only when the request authenticated as the process-internal user (the scheduler path), never from arbitrary HTTP/IM clients.
+- Scheduled background runs resolve to the `scheduled` interaction policy through trusted `context.non_interactive=true` and therefore exclude `ask_clarification` from the lead-agent tool list. The legacy `context.non_interactive=true` key remains accepted only for internally authenticated scheduler calls during migration; arbitrary HTTP/IM clients cannot set it.
 
 Durable MCP task-management tools are added only while the process-local task submitter is installed. They expose bounded local task fields, including whether cancellation was requested, but never the remote handle. Cancellation records that request durably and returns immediately; the background service owns the remote call and retries. These remain ordinary business tools under an active skill's `allowed-tools` policy and must be declared explicitly.
