New private member in `AgentLoop`: + ```cpp + std::vector> abandoned_tasks_; + static constexpr size_t kMaxAbandonedTasks = 32; + ``` + +2. New private method `drain_abandoned_tasks()`: + - Non-blocking poll: `f.wait_for(0ms) == ready` + - Remove completed futures from the vector via erase-remove idiom + - Called at the start of each turn in `run_loop()` + +3. Timeout branch in `handle_tool_calls()`: + - Call `ctx.cancellation->cancel()` to signal the tool thread + - `std::move(result_future)` into `abandoned_tasks_` (avoids blocking destructor) + - If `abandoned_tasks_.size() >= kMaxAbandonedTasks`, log error and `.get()` the oldest + (safety valve against unbounded accumulation) + +4. Add `int abandoned_tasks = 0` to `RunMetrics` for observability, incremented on each timeout. + +**Rationale:** Claude Code uses this same pattern — abandoned futures are collected and +polled non-blockingly. The cancellation token is signaled on timeout as a cooperative hint; +tools that check it can stop early. Tools that don't check it run to completion in the +background and get cleaned up in a subsequent `drain_abandoned_tasks()` call. + +**Files:** `libs/loop/include/merak/agent_loop.hpp` (+4), `libs/loop/src/agent_loop.cpp` (+25) + +--- + +### Fix 3 — `fan_out` error result constructed but never stored + +**Problem:** In `SubAgentRunner::fan_out()`, the catch block constructs `AgentResponse err` +and logs a warning, but never inserts the error into the `results` map. The caller receives +N-1 results for N tasks with no indication of which task failed. + +**Design (restructure to capture agent_id in catch):** + +Current code iterates `batch` futures indexed by position. The agent_id is captured in the +lambda that produced each future, but lost in the batch collection loop. Fix: + +```cpp +for (size_t i = 0; i < batch.size(); i++) { + // tasks[batch_start + i] holds the original Delegation with agent_id + auto& d = tasks[batch_start + i]; + try { + auto result = batch[i].get(); + results[result.first] = result.second; + } catch (const std::exception& e) { + AgentResponse err; + err.text = std::string("Sub-agent error: ") + e.what(); + results[d.agent_id] = err; // store with agent_id as key + spdlog::warn("SubAgentRunner: fan_out task '{}' failed: {}", d.agent_id, e.what()); + } +} +``` + +This requires tracking `batch_start` alongside the `batch` vector throughout the while loop, +so the index into `tasks` can be reconstructed for the catch block. + +**Files:** `libs/loop/src/sub_agent_runner.cpp` (~8 lines changed) + +--- + +### Fix 4 — `restricted_tools` hardcoded string list should use `ToolDomain` + +**Problem:** TurnGuard detects world-query-only loops correctly via `ToolDomain::WorldQuery` +bitflags (in `agent_loop.cpp`), but the remediation — restricting tools — uses a hardcoded +list of 5 tool names in `turn_guard.cpp`.
