feat: add path completion, LCP-based suggestions, and validator tests

- Refactored `FalyxCompleter` to support longest common prefix (LCP) completions by default.
- Added `_ensure_quote` helper to auto-quote completions containing spaces/tabs.
- Integrated `_yield_lcp_completions` for consistent completion insertion logic.
- Added `_suggest_paths()` helper to dynamically suggest filesystem paths for arguments of type `Path`.
- Integrated path completion into `suggest_next()` for both positional and flagged arguments.
- Updated `argument_examples.py` to include a `--path` argument (`Path | None`), demonstrating file path completion.
- Enabled `CompleteStyle.COLUMN` for tab-completion menu formatting in interactive sessions.
- Improved bottom bar docstring formatting with fenced code block examples.
- Added safeguard to `word_validator` to reject `"N"` since it’s reserved for `yes_no_validator`.
- Improved help panel rendering for commands (using `Padding` + `Panel`).
- Added full test coverage for:
  - `FalyxCompleter` and LCP behavior (`tests/test_completer/`)
  - All validators (`tests/test_validators/`)
- Bumped version to 0.1.80.

 # Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
-"""action.py
+"""
+Defines `Action`, the core atomic unit in the Falyx CLI framework, used to wrap and
+execute a single callable or coroutine with structured lifecycle support.
 
-Core action system for Falyx.
+An `Action` is the simplest building block in Falyx's execution model, enabling
+developers to turn ordinary Python functions into hookable, retryable, introspectable
+workflow steps. It supports synchronous or asynchronous callables, argument injection,
+rollback handlers, and retry policies.
 
-This module defines the building blocks for executable actions and workflows,
+Key Features:
-providing a structured way to compose, execute, recover, and manage sequences of
+- Lifecycle hooks: `before`, `on_success`, `on_error`, `after`, `on_teardown`
-operations.
+- Optional `last_result` injection for chained workflows
+- Retry logic via configurable `RetryPolicy` and `RetryHandler`
+- Rollback function support for recovery and undo behavior
+- Rich preview output for introspection and dry-run diagnostics
 
-All actions are callable and follow a unified signature:
+Usage Scenarios:
-    result = action(*args, **kwargs)
+- Wrapping business logic, utility functions, or external API calls
+- Converting lightweight callables into structured CLI actions
+- Composing workflows using `Action`, `ChainedAction`, or `ActionGroup`
 
-Core guarantees:
+Example:
-- Full hook lifecycle support (before, on_success, on_error, after, on_teardown).
+    def compute(x, y):
-- Consistent timing and execution context tracking for each run.
+        return x + y
-- 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(
-- Action: wraps a function or coroutine into a standard executable unit.
+        name="AddNumbers",
-- ChainedAction: runs actions sequentially, optionally injecting last results.
+        action=compute,
-- ActionGroup: runs actions in parallel and gathers results.
+        args=(2, 3),
-- 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.
+This module serves as the foundation for building robust, observable,
+and composable CLI automation flows in Falyx.

-from typing import Any
+Defines `ActionFactory`, a dynamic Falyx Action that defers the construction of its
+underlying logic to runtime using a user-defined factory function.
+
+This pattern is useful when the specific Action to execute cannot be determined until
+execution time—such as when branching on data, generating parameterized HTTP requests,
+or selecting configuration-aware flows. `ActionFactory` integrates seamlessly with the
+Falyx lifecycle system and supports hook propagation, teardown registration, and
+contextual previewing.
+
+Key Features:
+- Accepts a factory function that returns a `BaseAction` instance
+- Supports injection of `last_result` and arbitrary args/kwargs
+- Integrates into chained or standalone workflows
+- Automatically previews generated action tree
+- Propagates shared context and teardown hooks to the returned action
+
+Common Use Cases:
+- Conditional or data-driven action generation
+- Configurable workflows with dynamic behavior
+- Adapter for factory-style dependency injection in CLI flows
+
+Example:
+    def generate_request_action(env):
+        return HTTPAction(f"GET /status/{env}", url=f"https://api/{env}/status")
+
+    ActionFactory(
+        name="GetEnvStatus",
+        factory=generate_request_action,
+        inject_last_result=True,

+"""
+Defines `ActionGroup`, a Falyx Action that executes multiple sub-actions concurrently
+using asynchronous parallelism.
+
+`ActionGroup` is designed for workflows where several independent actions can run
+simultaneously to improve responsiveness and reduce latency. It ensures robust error
+isolation, shared result tracking, and full lifecycle hook integration while preserving
+Falyx's introspectability and chaining capabilities.
+
+Key Features:
+- Executes all actions in parallel via `asyncio.gather`
+- Aggregates results as a list of `(name, result)` tuples
+- Collects and reports multiple errors without interrupting execution
+- Compatible with `SharedContext`, `OptionsManager`, and `last_result` injection
+- Teardown-aware: propagates teardown registration across all child actions
+- Fully previewable via Rich tree rendering
+
+Use Cases:
+- Batch execution of independent tasks (e.g., multiple file operations, API calls)
+- Concurrent report generation or validations
+- High-throughput CLI pipelines where latency is critical
+
+Raises:
+- `EmptyGroupError`: If no actions are added to the group
+- `Exception`: Summarizes all failed actions after execution
+
+Example:
+    ActionGroup(
+        name="ParallelChecks",
+        actions=[Action(...), Action(...), ChainedAction(...)],
+    )
+
+This module complements `ChainedAction` by offering breadth-wise (parallel) execution
+as opposed to depth-wise (sequential) execution.

+"""
+Defines `ChainedAction`, a core Falyx construct for executing a sequence of actions
+in strict order, optionally injecting results from previous steps into subsequent ones.
+
+`ChainedAction` is designed for linear workflows where each step may depend on
+the output of the previous one. It supports rollback semantics, fallback recovery,
+and advanced error handling using `SharedContext`. Literal values are supported via
+automatic wrapping with `LiteralInputAction`.
+
+Key Features:
+- Executes a list of actions sequentially
+- Optional `auto_inject` to forward `last_result` into each step
+- Supports fallback recovery using `FallbackAction` when an error occurs
+- Rollback stack to undo already-completed actions on failure
+- Integrates with the full Falyx hook lifecycle
+- Previews and introspects workflow structure via `Rich`
+
+Use Cases:
+- Ordered pipelines (e.g., build → test → deploy)
+- Data transformations or ETL workflows
+- Linear decision trees or interactive wizards
+
+Special Behaviors:
+- Literal inputs (e.g., strings, numbers) are converted to `LiteralInputAction`
+- If an action raises and is followed by a `FallbackAction`, it will be skipped and recovered
+- If a `BreakChainSignal` is raised, the chain stops early and rollbacks are triggered
+
+Raises:
+- `EmptyChainError`: If no actions are present
+- `BreakChainSignal`: When explicitly triggered by a child action
+- `Exception`: For all unhandled failures during chained execution
+
+Example:
+    ChainedAction(
+        name="DeployFlow",
+        actions=[
+            ActionGroup(
+                name="PreDeploymentChecks",

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+Defines `ConfirmAction`, a Falyx Action that prompts the user for confirmation
+before continuing execution.
+
+`ConfirmAction` supports a wide range of confirmation strategies, including:
+- Yes/No-style prompts
+- OK/Cancel dialogs
+- Typed confirmation (e.g., "CONFIRM" or "DELETE")
+- Acknowledge-only flows
+
+It is useful for adding safety gates, user-driven approval steps, or destructive
+operation guards in CLI workflows. This Action supports both interactive use and
+non-interactive (headless) behavior via `never_prompt`, as well as full hook lifecycle
+integration and optional result passthrough.
+
+Key Features:
+- Supports all common confirmation types (see `ConfirmType`)
+- Integrates with `PromptSession` for prompt_toolkit-based UX
+- Configurable fallback word validation and behavior on cancel
+- Can return the injected `last_result` instead of a boolean
+- Fully compatible with Falyx hooks, preview, and result injection
+
+Use Cases:
+- Safety checks before deleting, pushing, or overwriting resources
+- Gatekeeping interactive workflows
+- Validating irreversible or sensitive operations
+
+Example:
+    ConfirmAction(
+        name="ConfirmDeploy",
+        message="Are you sure you want to deploy to production?",
+        confirm_type="yes_no_cancel",
+    )
+
+Raises:
+- `CancelSignal`: When the user chooses to abort the action
+- `ValueError`: If an invalid `confirm_type` is provided

+"""
+Defines `FallbackAction`, a lightweight recovery Action used within `ChainedAction`
+pipelines to gracefully handle errors or missing results from a preceding step.
+
+When placed immediately after a failing or null-returning Action, `FallbackAction`
+injects the `last_result` and checks whether it is `None`. If so, it substitutes a
+predefined fallback value and allows the chain to continue. If `last_result` is valid,
+it is passed through unchanged.
+
+This mechanism allows workflows to recover from failure or gaps in data
+without prematurely terminating the entire chain.
+
+Key Features:
+- Injects and inspects `last_result`
+- Replaces `None` with a fallback value
+- Consumes upstream errors when used with `ChainedAction`
+- Fully compatible with Falyx's preview and hook systems
+
+Typical Use Cases:
+- Graceful degradation in chained workflows
+- Providing default values when earlier steps are optional
+- Replacing missing data with static or precomputed values
+
+Example:
+    ChainedAction(
+        name="FetchWithFallback",
+        actions=[
+            Action("MaybeFetchRemoteAction", action=fetch_data),
+            FallbackAction(fallback={"data": "default"}),
+            Action("ProcessDataAction", action=process_data),
+        ],
+        auto_inject=True,
+    )
+
+The `FallbackAction` ensures that even if `MaybeFetchRemoteAction` fails or returns
+None, `ProcessDataAction` still receives a usable input.

+"""
+Defines `LiteralInputAction`, a lightweight Falyx Action that injects a static,
+predefined value into a `ChainedAction` workflow.
+
+This Action is useful for embedding literal values (e.g., strings, numbers,
+dicts) as part of a CLI pipeline without writing custom callables. It behaves
+like a constant-returning function that can serve as the starting point,
+fallback, or manual override within a sequence of actions.
+
+Key Features:
+- Wraps any static value as a Falyx-compatible Action
+- Fully hookable and previewable like any other Action
+- Enables declarative workflows with no required user input
+- Compatible with auto-injection and shared context in `ChainedAction`
+
+Common Use Cases:
+- Supplying default parameters or configuration values mid-pipeline
+- Starting a chain with a fixed value (e.g., base URL, credentials)
+- Bridging gaps between conditional or dynamically generated Actions
+
+Example:
+    ChainedAction(
+        name="SendStaticMessage",
+        actions=[
+            LiteralInputAction("hello world"),
+            SendMessageAction(),
+        ]
+    )
+
+The `LiteralInputAction` is a foundational building block for pipelines that
+require predictable, declarative value injection at any stage.

+"""
+Defines `LoadFileAction`, a Falyx Action for reading and parsing the contents of a file
+at runtime in a structured, introspectable, and lifecycle-aware manner.
+
+This action supports multiple common file types—including plain text, structured data
+formats (JSON, YAML, TOML), tabular formats (CSV, TSV), XML, and raw Path objects—
+making it ideal for configuration loading, data ingestion, and file-driven workflows.
+
+It integrates seamlessly with Falyx pipelines and supports `last_result` injection,
+Rich-powered previews, and lifecycle hook execution.
+
+Key Features:
+- Format-aware parsing for structured and unstructured files
+- Supports injection of `last_result` as the target file path
+- Headless-compatible via `never_prompt` and argument overrides
+- Lifecycle hooks: before, success, error, after, teardown
+- Preview renders file metadata, size, modified timestamp, and parsed content
+- Fully typed and alias-compatible via `FileType`
+
+Supported File Types:
+- `TEXT`: Raw text string (UTF-8)
+- `PATH`: The file path itself as a `Path` object
+- `JSON`, `YAML`, `TOML`: Parsed into `dict` or `list`
+- `CSV`, `TSV`: Parsed into `list[list[str]]`
+- `XML`: Returns the root `ElementTree.Element`
+
+Example:
+    LoadFileAction(
+        name="LoadSettings",
+        file_path="config/settings.yaml",
+        file_type="yaml"
+    )
+
+This module is a foundational building block for file-driven CLI workflows in Falyx.
+It is often paired with `SaveFileAction`, `SelectionAction`, or `ConfirmAction` for
+robust and interactive pipelines.

+Defines `MenuAction`, a one-shot, interactive menu-style Falyx Action that presents
+a set of labeled options to the user and executes the corresponding action based on
+their selection.
+
+Unlike the persistent top-level Falyx menu, `MenuAction` is intended for embedded,

+non-interactive (headless) usage, integrates fully with the Falyx hook lifecycle,
+and allows optional defaulting or input injection from previous actions.
+
+Each selectable item is defined in a `MenuOptionMap`, mapping a single-character or
+keyword to a `MenuOption`, which includes a description and a corresponding `BaseAction`.
+
+Key Features:
+- Renders a Rich-powered multi-column menu table
+- Accepts custom prompt sessions or tables
+- Supports `last_result` injection for context-aware defaults
+- Gracefully handles `BackSignal` and `QuitSignal` for flow control
+- Compatible with preview trees and introspection tools
+
+Use Cases:
+- In-workflow submenus or branches
+- Interactive control points in chained or grouped workflows
+- Configurable menus for multi-step user-driven automation

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+Defines `ProcessAction`, a Falyx Action that executes a blocking or CPU-bound function
+in a separate process using `concurrent.futures.ProcessPoolExecutor`.
+
+This is useful for offloading expensive computations or subprocess-compatible operations
+from the main event loop, while maintaining Falyx's composable, hookable, and injectable
+execution model.
+
+`ProcessAction` mirrors the behavior of a normal `Action`, but ensures isolation from
+the asyncio event loop and handles serialization (pickling) of arguments and injected
+state.
+
+Key Features:
+- Runs a callable in a separate Python process
+- Compatible with `last_result` injection for chained workflows
+- Validates that injected values are pickleable before dispatch
+- Supports hook lifecycle (`before`, `on_success`, `on_error`, etc.)
+- Custom executor support for reuse or configuration
+
+Use Cases:
+- CPU-intensive operations (e.g., image processing, simulations, data transformations)
+- Blocking third-party libraries that don't cooperate with asyncio
+- CLI workflows that require subprocess-level parallelism or safety
+
+Example:
+    ProcessAction(
+        name="ComputeChecksum",
+        action=calculate_sha256,
+        args=("large_file.bin",),
+    )
+
+Raises:
+- `ValueError`: If an injected value is not pickleable
+- `Exception`: Propagated from the subprocess on failure
+
+This module enables structured offloading of workload in CLI pipelines while maintaining
+full introspection and lifecycle management.

+    """
+    Displays a single-line interactive prompt for selecting an option from a menu.
+
+    `PromptMenuAction` is a lightweight alternative to `MenuAction`, offering a more
+    compact selection interface. Instead of rendering a full table, it displays
+    available keys inline as a placeholder (e.g., `A | B | C`) and accepts the user's
+    input to execute the associated action.
+
+    Each key is defined in a `MenuOptionMap`, which maps to a `MenuOption` containing
+    a description and an executable action.
+
+    Key Features:
+    - Minimal UI: rendered as a single prompt line with placeholder
+    - Optional fallback to `default_selection` or injected `last_result`
+    - Fully hookable lifecycle (before, success, error, after, teardown)
+    - Supports reserved keys and structured error recovery
+
+    Args:
+        name (str): Name of the action. Used for logging and debugging.
+        menu_options (MenuOptionMap): A mapping of keys to `MenuOption` objects.
+        prompt_message (str): Text displayed before user input (default: "Select > ").
+        default_selection (str): Fallback key if no input is provided.
+        inject_last_result (bool): Whether to use `last_result` as a fallback input key.
+        inject_into (str): Kwarg name under which to inject the last result.
+        prompt_session (PromptSession | None): Custom Prompt Toolkit session.
+        never_prompt (bool): If True, skips user input and uses `default_selection`.
+        include_reserved (bool): Whether to include reserved keys in logic and preview.
+
+    Returns:
+        Any: The result of the selected option's action.
+
+    Raises:
+        BackSignal: If the user signals to return to the previous menu.
+        QuitSignal: If the user signals to exit the CLI entirely.
+        ValueError: If `never_prompt` is enabled but no fallback is available.
+        Exception: If an error occurs during the action's execution.
+
+    Example:
+        PromptMenuAction(
+            name="HotkeyPrompt",
+            menu_options=MenuOptionMap(options={

 # Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
-"""select_file_action.py"""
+"""
+Defines `SelectFileAction`, a Falyx Action that allows users to select one or more
+files from a target directory and optionally return either their content or path,
+parsed based on a selected `FileType`.
+
+This action combines rich interactive selection (via `SelectionOption`) with
+format-aware parsing, making it ideal for loading external resources, injecting
+config files, or dynamically selecting inputs mid-pipeline.
+
+Supports filtering by file suffix, customizable prompt layout, multi-select mode,
+and automatic content parsing for common formats.
+
+Key Features:
+- Lists files from a directory and renders them in a Rich-powered menu
+- Supports suffix filtering (e.g., only `.yaml` or `.json` files)
+- Returns content parsed as `str`, `dict`, `list`, or raw `Path` depending on `FileType`
+- Works in single or multi-selection mode
+- Fully compatible with Falyx hooks and context system
+- Graceful cancellation via `CancelSignal`
+
+Supported Return Types (`FileType`):
+- `TEXT`: UTF-8 string content
+- `PATH`: File path object (`Path`)
+- `JSON`, `YAML`, `TOML`: Parsed dictionaries or lists
+- `CSV`, `TSV`: `list[list[str]]` from structured rows
+- `XML`: `ElementTree.Element` root object
+
+Use Cases:
+- Prompting users to select a config file during setup
+- Dynamically loading data into chained workflows
+- CLI interfaces that require structured file ingestion
+
+Example:
+    SelectFileAction(
+        name="ChooseConfigFile",
+        directory="configs/",
+        suffix_filter=".yaml",
+        return_type="yaml",
+    )
+
+This module is ideal for use cases where file choice is deferred to runtime
+and needs to feed into structured automation pipelines.

+Defines `SelectionAction`, a highly flexible Falyx Action for interactive or headless
+selection from a list or dictionary of user-defined options.
+
+This module powers workflows that require prompting the user for input, selecting
+configuration presets, branching execution paths, or collecting multiple values
+in a type-safe, hook-compatible, and composable way.
+
+Key Features:
+- Supports both flat lists and structured dictionaries (`SelectionOptionMap`)
+- Handles single or multi-selection with configurable separators
+- Returns results in various formats (key, value, description, item, or mapping)
+- Integrates fully with Falyx lifecycle hooks and `last_result` injection
+- Works in interactive (`prompt_toolkit`) and non-interactive (headless) modes
+- Renders a Rich-based table preview for diagnostics or dry runs
+
+Usage Scenarios:
+- Guided CLI wizards or configuration menus
+- Dynamic branching or conditional step logic
+- User-driven parameterization in chained workflows
+- Reusable pickers for environments, files, datasets, etc.
+
+Example:
+    SelectionAction(
+        name="ChooseMode",
+        selections={"dev": "Development", "prod": "Production"},
+        return_type="key"
+    )
+
+This module is foundational to creating expressive, user-centered CLI experiences

+    inputs. It renders a prompt (unless `never_prompt=True`), validates user input
+    or injected defaults, and returns a structured result based on the specified
+    `return_type`.
+
+    It is commonly used for item pickers, confirmation flows, dynamic parameterization,
+    or guided workflows in interactive or headless CLI pipelines.
+
+    Features:
+    - Supports single or multiple selections (`number_selections`)
+    - Dictionary mode allows rich metadata (description, value, style)
+    - Flexible return values: key(s), value(s), item(s), description(s), or mappings
+    - Fully hookable lifecycle (`before`, `on_success`, `on_error`, `after`, `on_teardown`)
+    - Default selection logic supports previous results (`last_result`)
+    - Can run in headless mode using `never_prompt` and fallback defaults
+
+    Args:
+        name (str): Action name for tracking and logging.
+        selections (list[str] | dict[str, SelectionOption] | dict[str, Any]):
+            The available choices. If a plain dict is passed, values are converted
+            into `SelectionOption` instances.
+        title (str): Title shown in the selection UI (default: "Select an option").
+        columns (int): Number of columns in the selection table.
+        prompt_message (str): Input prompt for the user (default: "Select > ").
+        default_selection (str | list[str]): Key(s) or index(es) used as fallback selection.
+        number_selections (int | str): Max number of choices allowed (or "*" for unlimited).
+        separator (str): Character used to separate multi-selections (default: ",").
+        allow_duplicates (bool): Whether duplicate selections are allowed.
+        inject_last_result (bool): If True, attempts to inject the last result as default.
+        inject_into (str): The keyword name for injected value (default: "last_result").
+        return_type (SelectionReturnType | str): The type of result to return.
+        prompt_session (PromptSession | None): Reused or customized prompt_toolkit session.
+        never_prompt (bool): If True, skips prompting and uses default_selection or last_result.
+        show_table (bool): Whether to render the selection table before prompting.
+
+    Returns:
+        Any: The selected result(s), shaped according to `return_type`.
+
+    Raises:
+        CancelSignal: If the user chooses the cancel option.
+        ValueError: If configuration is invalid or no selection can be resolved.
+        TypeError: If `selections` is not a supported type.

+Defines `SignalAction`, a lightweight Falyx Action that raises a `FlowSignal`
+(such as `BackSignal`, `QuitSignal`, or `BreakChainSignal`) during execution to
+alter or exit the CLI flow.
+
+Unlike traditional actions, `SignalAction` does not return a result—instead, it raises
+a signal to break, back out, or exit gracefully. Despite its minimal behavior,
+it fully supports Falyx's hook lifecycle, including `before`, `on_error`, `after`,
+and `on_teardown`—allowing it to trigger logging, audit events, UI updates, or custom
+telemetry before halting flow.
+
+Key Features:
+- Declaratively raises a `FlowSignal` from within any Falyx workflow
+- Works in menus, chained actions, or conditionals
+- Hook-compatible: can run pre- and post-signal lifecycle hooks
+- Supports previewing and structured introspection
+
+Use Cases:
+- Implementing "Back", "Cancel", or "Quit" options in `MenuAction` or `PromptMenuAction`
+- Triggering an intentional early exit from a `ChainedAction`
+- Running cleanup hooks before stopping execution
+
+Example:
+    SignalAction("ExitApp", QuitSignal(), hooks=my_hook_manager)

+It supports dynamic prompt interpolation, prompt validation, default text fallback,
+and full lifecycle hook execution.
+
+Key Features:
+- Rich Prompt Toolkit integration for input and validation
+- Dynamic prompt formatting using `last_result` injection
+- Optional `Validator` support for structured input (e.g., emails, numbers)
+- Hook lifecycle compatibility (before, on_success, on_error, after, teardown)
+- Preview support for introspection or dry-run flows
+
+Use Cases:
+- Asking for confirmation text or field input mid-chain
+- Injecting user-provided variables into automated pipelines
+- Interactive menu or wizard experiences
+
+Example:
+    UserInputAction(
+        name="GetUsername",
+        prompt_message="Enter your username > ",
+        validator=Validator.from_callable(lambda s: len(s) > 0),
+    )

 # Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
-"""bottom_bar.py"""
+"""
+Provides the `BottomBar` class for managing a customizable bottom status bar in
+Falyx-based CLI applications.
+
+The bottom bar is rendered using `prompt_toolkit` and supports:
+- Rich-formatted static content
+- Live-updating value trackers and counters
+- Toggle switches activated via Ctrl+<key> bindings
+- Config-driven visual and behavioral controls
+
+Each item in the bar is registered by name and rendered in columns across the
+bottom of the terminal. Toggles are linked to user-defined state accessors and
+mutators, and can be automatically bound to `OptionsManager` values for full
+integration with Falyx CLI argument parsing.
+
+Key Features:
+- Live rendering of structured status items using Rich-style HTML
+- Custom or built-in item types: static text, dynamic counters, toggles, value displays
+- Ctrl+key toggle handling via `prompt_toolkit.KeyBindings`
+- Columnar layout with automatic width scaling
+- Optional integration with `OptionsManager` for dynamic state toggling
+
+Example:
+    ```
+    bar = BottomBar(columns=3)
+    bar.add_static("env", "ENV: dev")
+    bar.add_toggle("d", "Debug", get_debug, toggle_debug)
+    bar.add_value_tracker("attempts", "Retries", get_retry_count)
+    bar.render()
+    ```
+
+Used by Falyx to provide a persistent UI element showing toggles, system state,
+and runtime telemetry below the input prompt.

-Configuration loader for Falyx CLI commands."""
+Configuration loader and schema definitions for the Falyx CLI framework.
+
+This module supports config-driven initialization of CLI commands and submenus
+from YAML or TOML files. It enables declarative command definitions, auto-imports
+Python callables from dotted paths, and wraps them in `Action` or `Command` objects
+as needed.
+
+Features:
+- Parses Falyx command and submenu definitions from YAML or TOML.
+- Supports hooks, retry policies, confirm prompts, spinners, aliases, and tags.
+- Dynamically imports Python functions/classes from `action:` strings.
+- Wraps user callables into Falyx `Command` or `Action` instances.
+- Validates prompt and retry configuration using `pydantic` models.
+
+Main Components:
+- `FalyxConfig`: Pydantic model for top-level config structure.
+- `RawCommand`: Intermediate command definition model from raw config.
+- `Submenu`: Schema for nested CLI menus.
+- `loader(path)`: Loads and returns a fully constructed `Falyx` instance.
+
+Typical Config (YAML):
+```yaml
+title: My CLI
+commands:
+  - key: A
+    description: Say hello
+    action: my_package.tasks.hello
+    aliases: [hi]
+    tags: [example]
+```
+
+Example:
+    from falyx.config import loader
+    cli = loader("falyx.yaml")
+    cli.run()

-introspecting the execution history of Falyx actions.
+execution—including context metadata, results, exceptions, duration, and tracebacks.
+It supports filtering, summarization, and visual inspection via a Rich-rendered table.
 
-The registry captures `ExecutionContext` instances from all executed actions, making it
+Designed for:
-easy to debug, audit, and visualize workflow behavior over time. It supports retrieval,
+- Workflow debugging and CLI diagnostics
-filtering, clearing, and formatted summary display.
+- Interactive history browsing or replaying previous runs
+- Providing user-visible `history` or `last-result` commands inside CLI apps
 
-Core Features:
+Key Features:
-- Stores all action execution contexts globally (with access by name).
+- Global, in-memory store of all `ExecutionContext` objects (by name, index, or full list)
-- Provides live execution summaries in a rich table format.
+- Thread-safe indexing and summary display
-- Enables creation of a built-in Falyx Action to print history on demand.
+- Traceback-aware result inspection and filtering by status (success/error)
-- Integrates with Falyx's introspectable and hook-driven execution model.
+- Used by built-in `History` command in Falyx CLI
-
-Intended for:
-- Debugging and diagnostics
-- Post-run inspection of CLI workflows
-- Interactive tools built with Falyx
 
 Example:
     from falyx.execution_registry import ExecutionRegistry as er
+
+    # Record a context
     er.record(context)
+
+    # Display a rich table summary
     er.summary()

+    # Print the last non-ignored result
+    er.summary(last_result=True)
+
+    # Clear execution history
+    er.summary(clear=True)
+
+Note:
+    The registry is volatile and cleared on each process restart or when `clear()` is called.
+    All data is retained in memory only.
+
+Public Interface:
+- record(context): Log an ExecutionContext and assign index.
+- get_all(): List all stored contexts.
+- get_by_name(name): Retrieve all contexts by action name.
+- get_latest(): Retrieve the most recent context.
+- clear(): Reset the registry.

+- `get_arg_parsers()`: Factory for generating full parser suite.
+- `get_root_parser()`: Creates the root-level CLI parser with global options.
+- `get_subparsers()`: Helper to attach subcommand parsers to the root parser.

+"""
+Centralized spinner rendering for Falyx CLI.
+
+This module provides the `SpinnerManager` class, which manages a collection of
+Rich spinners that can be displayed concurrently during long-running tasks.
+
+Key Features:
+    • Automatic lifecycle management:
+        - Starts a single Rich `Live` loop when the first spinner is added.
+        - Stops and clears the display when the last spinner is removed.
+    • Thread/async-safe start logic via a lightweight lock to prevent
+      duplicate Live loops from being launched.
+    • Supports multiple spinners running simultaneously, each with its own
+      text, style, type, and speed.
+    • Integrates with Falyx's OptionsManager so actions and commands can
+      declaratively request spinners without directly managing terminal state.
+
+Classes:
+    SpinnerData:
+        Lightweight container for individual spinner settings (message,
+        type, style, speed) and its underlying Rich `Spinner` object.
+    SpinnerManager:
+        Manages all active spinners, handles Live rendering, and provides
+        methods to add, update, and remove spinners.
+
+Example:
+    ```python
+    >>> manager = SpinnerManager()
+    >>> await manager.add("build", "Building project…", spinner_type="dots")
+    >>> await manager.add("deploy", "Deploying to AWS…", spinner_type="earth")
+    # Both spinners animate in one unified Live panel
+    >>> manager.remove("build")
+    >>> manager.remove("deploy")
+    ```
+
+Design Notes:
+    • SpinnerManager should only create **one** Live loop at a time.
+    • When no spinners remain, the Live panel is cleared (`transient=True`)
+      so the CLI output returns to a clean state.
+    • Hooks in `falyx.hooks` (spinner_before_hook / spinner_teardown_hook)
+      call into this manager automatically when `spinner=True` is set on
+      an Action or Command.
