Module segment 

Compatibility surface for segmented Oniro trials.

The implementation is deliberately split into private plan, configuration, runtime-command, and orchestration layers. These re-exports retain the established atune_oniro::segment::* paths for existing callers.

Structs

Segment

One oniro run invocation in a segmented trial.

SegmentPlan

An immutable, bounded segmentation policy.

SegmentedObjective

Runs a trial as a sequence of resumable oniro run operations.

Enums

RungFloor

Policy for refusing segments below an algorithm’s learn floor.

Constants

DEFAULT_FIDELITY_KEY

The dotted config key carrying a trial’s total fidelity.

DESCRIPTORS_PER_PROCESS

Descriptor units charged for one process’s pipes and cancellation sockets.

FLOOR_GATED_ALGOS

Algorithms for which the config exposes an env-step learn gate.

MAX_SEGMENTS

The maximum number of processes one segmented trial may spawn.

MAX_TOTAL_DESCRIPTORS

Maximum descriptor units admitted by one objective lifetime.

MAX_TOTAL_OPERATIONS

Maximum train/eval operations admitted by one objective lifetime.

MAX_TOTAL_PROCESSES

Maximum process invocations admitted by one objective lifetime.

MAX_TRIALS

Maximum logical trials admitted by one objective lifetime.

MAX_TRIAL_DURATION

The default ceiling on the wall clock one segmented trial may consume.

RESUME_BLOCKED_SUFFIXES

Shape-like config leaves that must remain fixed across checkpoint resumes.

Functions

fork_safe_pbt

Builds a PBT scheduler that cannot perturb checkpoint shape parameters.

learn_floor

Finds the SAC env-step learn floor in a complete config.

render_param

Renders one sampled value using the executor’s stable textual convention.

resume_blocked_params

Returns numeric parameters that must not change across a checkpoint fork.
