Represents a Directed Acyclic Graph (DAG) of Parslet tasks. This class is responsible for constructing the task graph based on declared

Executes tasks defined in a Parslet DAG in the correct topological order. The DAGRunner uses a `ThreadPoolExecutor` to run tasks concurrentl

Evaluate declarative context requirements for Parslet tasks. Parameters ---------- enabled : Iterable[str] | None, optional Manua

Replace Dask delayed constructs with Parslet equivalents.

Decide worker pool size based on system resources.

Representation of a single task in the interoperability graph.

Snapshot of the system's current power conditions.

Simple resource-aware scheduler for DAGRunner.

Replace Parsl decorators and APIs with Parslet equivalents.

Represents the placeholder for the future result of a Parslet task. When a function decorated with `@parslet_task` is called, it does not

Custom exception raised when Graphviz executable (e.g., 'dot') is not found by `pydot`. This error indicates that while `pydot` might be

Result of model prediction.

Lightweight container for system resource metrics.

Raised when a security sentry blocks an operation.

Task skipped because system battery level is too low.

Raised when system battery is below threshold.

Manage task checkpoints using a simple JSON file.

Generate high-touch concierge experiences for Parslet runs.

Bundle of useful counters about a DAG run.

Task skipped because its context requirements were not satisfied.

Structured result describing a context evaluation.

Custom exception raised when a cycle is detected in the task dependency graph. This error indicates that the defined task dependencies f

Hybrid policy that considers task metadata and power state.

Copy result files to a remote destination using ``scp`` if available.

Container for a task graph used in conversions.

Raised when system RAM is below threshold.

Replace Parslet decorators with Parsl equivalents.

Custom exception raised when `pydot` library is required but not found. This typically occurs when trying to use DOT or PNG export functiona

Task failed due to system resource exhaustion (e.g., memory).

Stub model predicting based on pixel mean.

Stub model predicting based on pixel standard deviation.

Custom exception raised when a task cannot run because one of its upstream dependencies failed. Attributes: skipped_task_id (str

Minimal stub of Parsl's ``DataFlowKernel``. Instantiating this class issues a warning since Parslet manages task scheduling internally.

Security layer with multiple levels.

Small protocol subset of :class:`parslet.core.runner.DAGRunner`.
