+

+    - Parallel execution of all contained actions.
+    - Shared last_result injection across all actions if configured.
+    - Aggregated collection of individual results as (name, result) pairs.
+    - Hook lifecycle support (before, on_success, on_error, after, on_teardown).
+    - Error aggregation: captures all action errors and reports them together.
+
+    Behavior:
+    - If any action fails, the group collects the errors but continues executing
+      other actions without interruption.
+    - After all actions complete, ActionGroup raises a single exception summarizing
+      all failures, or returns all results if successful.
+
+    Best used for:
+    - Batch processing multiple independent tasks.
+    - Reducing latency for workflows with parallelizable steps.

+
+Core action system for Falyx.
+
+This module defines the building blocks for executable actions and workflows,
+providing a structured way to compose, execute, recover, and manage sequences of
+operations.
+
+All actions are callable and follow a unified signature:
+    result = action(*args, **kwargs)
+
+Core guarantees:
+- Full hook lifecycle support (before, on_success, on_error, after, on_teardown).
+- Consistent timing and execution context tracking for each run.
+- Unified, predictable result handling and error propagation.
+- Optional last_result injection to enable flexible, data-driven workflows.
+- Built-in support for retries, rollbacks, parallel groups, chaining, and fallback
+  recovery.
+
+Key components:
+- Action: wraps a function or coroutine into a standard executable unit.
+- ChainedAction: runs actions sequentially, optionally injecting last results.
+- ActionGroup: runs actions in parallel and gathers results.
+- ProcessAction: executes CPU-bound functions in a separate process.
+- LiteralInputAction: injects static values into workflows.
+- FallbackAction: gracefully recovers from failures or missing data.
+
+This design promotes clean, fault-tolerant, modular CLI and automation systems.

+    ShellAction wraps a shell command template for CLI pipelines.
+
+    This Action takes parsed input (from stdin, literal, or last_result),
+    substitutes it into the provided shell command template, and executes
+    the command asynchronously using subprocess.
+
+    Designed for quick integration with shell tools like `grep`, `ping`, `jq`, etc.
+
+    ⚠️ Security Warning:
+    By default, ShellAction uses `shell=True`, which can be dangerous with
+    unsanitized input. To mitigate this, set `safe_mode=True` to use `shell=False`
+    with `shlex.split()`.
+
+    Features:
+    - Automatically handles input parsing (str/bytes)
+    - `safe_mode=True` disables shell interpretation and runs with `shell=False`
+    - Captures stdout and stderr from shell execution
+    - Raises on non-zero exit codes with stderr as the error
+    - Result is returned as trimmed stdout string
+
+    Args:

+Defines the Command class for Falyx CLI.
+
+Commands are callable units representing a menu option or CLI task,
+wrapping either a BaseAction or a simple function. They provide:
+
+- Hook lifecycle (before, on_success, on_error, after, on_teardown)
+- Execution timing and duration tracking
+- Retry logic (single action or recursively through action trees)
+- Confirmation prompts and spinner integration
+- Result capturing and summary logging
+- Rich-based preview for CLI display

+Every Command is self-contained, configurable, and plays a critical role

+    Represents the runtime metadata and state for a single action execution.

+    integration with the Falyx hook system and execution registry, enabling lifecycle

+
+    Attributes:
+        name (str): The name of the action being executed.

+        kwargs (dict): Keyword arguments passed to the action.
+        action (BaseAction | Callable): The action instance being executed.
+        result (Any | None): The result of the action, if successful.
+        exception (BaseException | None): The exception raised, if execution failed.
+        start_time (float | None): High-resolution performance start time.
+        end_time (float | None): High-resolution performance end time.
+        start_wall (datetime | None): Wall-clock timestamp when execution began.
+        end_wall (datetime | None): Wall-clock timestamp when execution ended.
+        extra (dict): Metadata for custom introspection or special use by Actions.

+        shared_context (SharedContext | None): Optional shared context when running in
+                                               a chain or group.
+
+    Properties:
+        duration (float | None): The execution duration in seconds.
+        success (bool): Whether the action completed without raising an exception.
+        status (str): Returns "OK" if successful, otherwise "ERROR".
+
+    Methods:
+        start_timer(): Starts the timing and timestamp tracking.

+        to_log_line(): Returns a single-line log entry for metrics or tracing.

+        get_shared_context(): Returns the shared context or creates a default one.

+This module provides the `ExecutionRegistry`, a global class for tracking and
+introspecting the execution history of Falyx actions.
+
+The registry captures `ExecutionContext` instances from all executed actions, making it
+easy to debug, audit, and visualize workflow behavior over time. It supports retrieval,
+filtering, clearing, and formatted summary display.
+
+Core Features:
+- Stores all action execution contexts globally (with access by name).
+- Provides live execution summaries in a rich table format.
+- Enables creation of a built-in Falyx Action to print history on demand.
+- Integrates with Falyx's introspectable and hook-driven execution model.
+
+Intended for:
+- Debugging and diagnostics
+- Post-run inspection of CLI workflows
+- Interactive tools built with Falyx
