# Kernel Scheduler Handoff Seed

Status: controlled scheduler handoff metadata seed
Scope: report-only bridge from scheduler dispatch metadata to scheduler handoff intent.

## Purpose

This slice connects the scheduler dispatch seed to deterministic scheduler handoff metadata.

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

## Current Posture

The default request evaluates the scheduler dispatch seed and emits:

```text
handoff_status=scheduler-handoff-seed-ready
scheduler_dispatch_status=scheduler-dispatch-seed-ready
scheduler_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
handoff_count=4
no_effect=1
```

Authority remains denied:

```text
scheduler_handoff_allowed=0
scheduler_dispatch_allowed=0
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-handoff.sh
sh scripts/test-kernel-scheduler-handoff-report-runner.sh
```

Expected output:

```text
kernel_scheduler_handoff: ok
kernel_scheduler_handoff_report_runner: ok
```

## Non-claims

This slice does not schedule execution, hand off execution to a process, dispatch a runnable process, mutate run queues, enqueue or dequeue work, 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.
