# Kernel Scheduler Activation Seed

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

## Purpose

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

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

## Current Posture

The default request evaluates the scheduler handoff seed and emits:

```text
activation_status=scheduler-activation-seed-ready
scheduler_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
activation_count=4
no_effect=1
```

Authority remains denied:

```text
scheduler_activation_allowed=0
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
runtime_entry_allowed=0
hardware_effect_allowed=0
host_effect_allowed=0
```

## Validation

Run:

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

Expected output:

```text
kernel_scheduler_activation: ok
kernel_scheduler_activation_report_runner: ok
```

## Non-claims

This slice does not schedule execution, activate execution, enter runtime, 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.
