Module default_selector 

Default priority-then-FIFO selector for ready runs.

This module implements the default run selection policy for v0.1:

• Runs are selected by priority (higher values considered higher priority)
• Runs with the same priority are selected in FIFO order (earlier created_at first)
• Runs with identical priority and created_at are selected by RunId for full tie-breaking

Structs

ReadyRunSelectionInput

Selector-ready input that pairs a run with a pre-resolved snapshot priority.

SelectionResult

Result of running the default selector.

Functions

ready_inputs_from_index

Builds selector-ready inputs from a ready index.

select_ready_runs

Default selector that picks runs by priority (descending), FIFO (ascending created_at), and finally by RunId for full ties.
