# Kernel Scheduler Selection Seed

Status: controlled scheduler selection metadata seed
Scope: report-only bridge from scheduler credit metadata to scheduler candidate selection intent.

## Purpose

This slice connects the scheduler credit seed to deterministic scheduler selection metadata.

It does not select a runnable process, enqueue or dequeue work, dispatch, switch contexts, update scheduler credits, update quotas, write CPU usage, preempt execution, wake processes, persist state, or touch hardware. It records candidate selection declarations that future scheduler work can refine behind explicit authority gates.

## Current Posture

The default request evaluates the scheduler credit seed and emits:

```text
selection_status=scheduler-selection-seed-ready
scheduler_credit_status=scheduler-credit-seed-ready
preemption_status=preemption-seed-ready
time_accounting_status=time-accounting-seed-ready
context_switch_status=context-switch-seed-ready
run_queue_status=run-queue-seed-ready
scheduler_tick_status=scheduler-tick-seed-ready
timer_source_status=timer-source-seed-ready
selection_count=4
no_effect=1
```

Authority remains denied:

```text
scheduler_selection_allowed=0
dispatch_allowed=0
run_queue_mutation_allowed=0
context_switch_allowed=0
preemption_allowed=0
scheduler_credit_update_allowed=0
quota_update_allowed=0
cpu_usage_write_allowed=0
time_accounting_allowed=0
time_read_allowed=0
process_wake_allowed=0
hardware_effect_allowed=0
host_effect_allowed=0
```

## Validation

Run:

```sh
sh scripts/test-kernel-scheduler-selection.sh
sh scripts/test-kernel-scheduler-selection-report-runner.sh
```

Expected output:

```text
kernel_scheduler_selection: ok
kernel_scheduler_selection_report_runner: ok
```

## Non-claims

This slice does not schedule execution, select a runnable process, mutate run queues, perform context switches, read clocks, account CPU time, update quotas, update scheduler credits, preempt execution, wake processes, dispatch interrupts, perform I/O, boot hardware, or replace an operating system.
