 - **Execution Loop**: turns an Operator goal into a traced agent run. The Cortex–Action–Memory stack executes inside an observable Sandbox and emits structured trajectories: actions, intermediate states, tool outputs, and environmental feedback.
 - **Evolution Loop**: converts those trajectories into reusable capability. A Reflector → Curator pipeline distills successful strategies and recurring failure patterns into a per-(project, agent) **Playbook** that is injected into the next run's workspace (training-free), while the same signals can also be fed back into base-model training (training-based).
-- **Evaluation Loop** *(planned)*: attributes *why* a task failed using an **L1–L4 taxonomy** (Task Instruction Issue · DW Capability Issue · Environment Issue …), giving the Operator a targeted correction signal and routing structured failure attributions back into the Evolution Loop.
+- **Evaluation Loop** *(planned)*: analyzes failed task trajectories and attributes the root cause using an L1–L4 failure taxonomy, from high-level ownership to concrete failure mode. The results help the Operator provide targeted corrections and feed failure insights back into Experience Learning and future training.

 Sandbox capabilities are exposed as HTTP APIs. For the current Android emulator sandbox, `sandbox_acquire` returns `http_api_base_url`; the agent uses the built-in `curl` tool against that URL, so the sandbox runtime only needs to ship its HTTP server, not per-endpoint agent-side wrappers. See [§4.6](#46-sandbox-observable-execution-environments) for details.

 A Digital Worker needs different kinds of memory at very different time scales. Rather than putting everything into a single vector store, Sico splits memory into five layers, each backed by the storage that best fits its access pattern.
