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
+"""
+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.
+
+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.
+
+Key Features:
+- Lifecycle hooks: `before`, `on_success`, `on_error`, `after`, `on_teardown`
+- 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
+
+Usage Scenarios:
+- Wrapping business logic, utility functions, or external API calls
+- Converting lightweight callables into structured CLI actions
+- Composing workflows using `Action`, `ChainedAction`, or `ActionGroup`
+
+Example:
+    def compute(x, y):
+        return x + y
+
+    Action(
+        name="AddNumbers",
+        action=compute,
+        args=(2, 3),
+    )
+
+This module serves as the foundation for building robust, observable,
+and composable CLI automation flows in Falyx.

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+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",

+"""
+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.

+    ActionGroup executes multiple actions concurrently in parallel.
+
+    It is ideal for independent tasks that can be safely run simultaneously,
+    improving overall throughput and responsiveness of workflows.
+
+    Core features:
+    - 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.
+    - Isolating errors while maximizing successful execution.

+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.

+"""
+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",
+                actions=[
+                    Action(
+                        name="ValidateInputs",
+                        action=validate_inputs,

+            ),

+                action=upload,
+            ),

+"""
+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),

+            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,

+
+This Action is useful for embedding literal values (e.g., strings, numbers,

+- 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

+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:

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+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,
+self-contained decision points within a workflow. It supports both interactive and
+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
+
+Example:
+    MenuAction(
+        name="SelectEnv",
+        menu_options=MenuOptionMap(options={
+            "D": MenuOption("Deploy to Dev", DeployDevAction()),
+            "P": MenuOption("Deploy to Prod", DeployProdAction()),
+        }),
+        default_selection="D",
+    )
+
+This module is ideal for enabling structured, discoverable, and declarative
+menus in both interactive and programmatic CLI automation.

+    MenuAction displays a one-time interactive menu of predefined options,
+    each mapped to a corresponding Action.
+
+    Unlike the main Falyx menu system, `MenuAction` is intended for scoped,
+    self-contained selection logic—ideal for small in-flow menus, decision branches,
+    or embedded control points in larger workflows.
+
+    Each selectable item is defined in a `MenuOptionMap`, which maps a string key
+    to a `MenuOption`, bundling a description and a callable Action.
+
+    Key Features:
+    - One-shot selection from labeled actions
+    - Optional default or last_result-based selection
+    - Full hook lifecycle (before, success, error, after, teardown)
+    - Works with or without rendering a table (for headless use)
+    - Compatible with `BackSignal` and `QuitSignal` for graceful control flow exits
+
+    Args:
+        name (str): Name of the action. Used for logging and debugging.
+        menu_options (MenuOptionMap): Mapping of keys to `MenuOption` objects.
+        title (str): Table title displayed when prompting the user.
+        columns (int): Number of columns in the rendered table.
+        prompt_message (str): Prompt text displayed before selection.
+        default_selection (str): Key to use if no user input is provided.
+        inject_last_result (bool): Whether to inject `last_result` into args/kwargs.
+        inject_into (str): Key under which to inject `last_result`.
+        prompt_session (PromptSession | None): Custom session for Prompt Toolkit input.
+        never_prompt (bool): If True, skips interaction and uses default or last_result.
+        include_reserved (bool): Whether to include reserved keys (like 'X' for Exit).
+        show_table (bool): Whether to render the Rich menu table.
+        custom_table (Table | None): Pre-rendered Rich Table (bypasses auto-building).
+
+    Returns:
+        Any: The result of the selected option's Action.
+
+    Raises:
+        BackSignal: When the user chooses to return to a previous menu.
+        QuitSignal: When the user chooses to exit the program.
+        ValueError: If `never_prompt=True` but no default selection is resolvable.
+        Exception: Any error raised during the execution of the selected Action.
+
+    Example:
+        MenuAction(
+            name="ChooseBranch",
+            menu_options=MenuOptionMap(options={

+# 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.

+
+Supported formats: TEXT, JSON, YAML, TOML, CSV, TSV, XML
+
+Key Features:
+- Auto-serialization of Python data to structured formats
+- Flexible path control with directory creation and overwrite handling
+- Injection of data via chaining (`last_result`)
+- Preview mode with file metadata visualization
+
+Common use cases:
+- Writing processed results to disk
+- Logging artifacts from batch pipelines
+- Exporting config or user input to JSON/YAML for reuse

+    Saves data to a file in the specified format.
+
+    `SaveFileAction` serializes and writes input data to disk using the format
+    defined by `file_type`. It supports plain text and structured formats like
+    JSON, YAML, TOML, CSV, TSV, and XML. Files may be overwritten or appended
+    based on settings, and parent directories are created if missing.
+
+    Data can be provided directly via the `data` argument or dynamically injected
+    from the previous Action using `inject_last_result`.
+
+    Key Features:
+    - Format-aware saving with validation
+    - Lifecycle hook support (before, success, error, after, teardown)
+    - Chain-compatible via last_result injection
+    - Supports safe overwrite behavior and preview diagnostics
+
+    Args:
+        name (str): Name of the action. Used for logging and debugging.
+        file_path (str | Path): Destination file path.
+        file_type (FileType | str): Output format (e.g., "json", "yaml", "text").
+        mode (Literal["w", "a"]): File mode—write or append. Default is "w".
+        encoding (str): Encoding to use when writing files (default: "UTF-8").
+        data (Any): Data to save. If omitted, uses last_result injection.
+        overwrite (bool): Whether to overwrite existing files. Default is True.
+        create_dirs (bool): Whether to auto-create parent directories.
+        inject_last_result (bool): Inject previous result as input if enabled.
+        inject_into (str): Name of kwarg to inject last_result into (default: "data").

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+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(

+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 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")

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+Provides the `ExecutionRegistry`, a centralized runtime store for capturing and inspecting
+the execution history of Falyx actions.
+
+The registry automatically records every `ExecutionContext` created during action
+execution—including context metadata, results, exceptions, duration, and tracebacks.
+It supports filtering, summarization, and visual inspection via a Rich-rendered table.
+
+Designed for:
+- Workflow debugging and CLI diagnostics
+- Interactive history browsing or replaying previous runs
+- Providing user-visible `history` or `last-result` commands inside CLI apps
+
+Key Features:
+- Global, in-memory store of all `ExecutionContext` objects (by name, index, or full list)
+- Thread-safe indexing and summary display
+- Traceback-aware result inspection and filtering by status (success/error)
+- Used by built-in `History` command in Falyx CLI
+
+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.
+- summary(...): Rich console summary of stored execution results.

+Defines reusable lifecycle hooks for Falyx Actions and Commands.
+
+This module includes:
+- `spinner_before_hook`: Automatically starts a spinner before an action runs.
+- `spinner_teardown_hook`: Stops and clears the spinner after the action completes.
+- `ResultReporter`: A success hook that displays a formatted result with duration.
+- `CircuitBreaker`: A failure-aware hook manager that prevents repeated execution
+  after a configurable number of failures.
+
+These hooks can be registered on `HookManager` instances via lifecycle stages
+(`before`, `on_error`, `after`, etc.) to enhance resiliency and observability.
+
+Intended for use with:
+- Actions that require user feedback during long-running operations.
+- Retryable or unstable actions
+- Interactive CLI feedback
+- Safety checks prior to execution
+
+Example usage:
+    breaker = CircuitBreaker(max_failures=3)
+    hooks.register(HookType.BEFORE, breaker.before_hook)
+    hooks.register(HookType.ON_ERROR, breaker.error_hook)
+    hooks.register(HookType.AFTER, breaker.after_hook)

+# Falyx CLI Framework — (c) 2025 rtj.dev LLC — MIT Licensed
+"""
+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.

+    Manages multiple Rich spinners and handles their terminal rendering.
+
+    SpinnerManager maintains a registry of active spinners and a single

+    the Live loop starts automatically. When the last spinner is removed,
+    the Live loop stops and the panel clears (via `transient=True`).
+
+    This class is designed for integration with Falyx's `OptionsManager`
+    so any Action or Command can declaratively register spinners without
+    directly controlling terminal state.
+
+    Key Behaviors:
+        • Starts exactly one `Live` loop, protected by a start lock to prevent
+          duplicate launches in async/threaded contexts.
+        • Supports multiple simultaneous spinners, each with independent
+          text, style, and type.
+        • Clears the display when all spinners are removed.

+    Attributes:
+        console (Console): The Rich console used for rendering.
+        _spinners (dict[str, SpinnerData]): Internal store of active spinners.
+        _task (asyncio.Task | None): The running Live loop task, if any.
+        _running (bool): Indicates if the Live loop is currently active.

+General-purpose utilities and helpers for the Falyx CLI framework.
+
+This module includes asynchronous wrappers, logging setup, formatting utilities,
+and small type-safe enhancements such as `CaseInsensitiveDict` and coroutine enforcement.
+
+Features:
+- `ensure_async`: Wraps sync functions as async coroutines.
+- `chunks`: Splits an iterable into fixed-size chunks.
+- `CaseInsensitiveDict`: Dict subclass with case-insensitive string keys.
+- `setup_logging`: Configures Rich or JSON logging based on environment or container detection.
+- `get_program_invocation`: Returns the recommended CLI command to invoke the program.
+- `running_in_container`: Detects if the process is running inside a container.
+
+These utilities support consistent behavior across CLI rendering, logging,
+command parsing, and compatibility layers.

+- CommandValidator: Validates if the input matches a known command.
+- int_range_validator: Enforces numeric input within a range.
+- key_validator: Ensures the entered value matches a valid selection key.
+- yes_no_validator: Restricts input to 'Y' or 'N'.
+- word_validator / words_validator: Accepts specific valid words (case-insensitive).
+- MultiIndexValidator: Validates numeric list input (e.g. "1,2,3").
+- MultiKeyValidator: Validates string key list input (e.g. "A,B,C").
+
+These validators integrate directly into `PromptSession.prompt_async()` to
+enforce correctness and provide helpful error messages.
