# Kernel Runtime Entry Scheduler Return Observation View Seed

Status: controlled runtime-entry scheduler-return-observation-view metadata seed
Scope: report-only bridge from runtime-entry post-resume-observation-view metadata to declared scheduler-return observation metadata.

This slice connects runtime-entry post-resume-observation-view metadata to deterministic scheduler-return-observation-view metadata.

It remains no-effect and denied-by-default.

## Report Fields

The report exposes the chained runtime-entry path:

```text
scheduler_return_observation_view_status=runtime-entry-scheduler-return-observation-view-seed-ready
runtime_entry_post_resume_observation_view_status=runtime-entry-post-resume-observation-view-seed-ready
runtime_entry_user_mode_resume_view_status=runtime-entry-user-mode-resume-view-seed-ready
runtime_entry_syscall_exit_view_status=runtime-entry-syscall-exit-view-seed-ready
runtime_entry_syscall_return_view_status=runtime-entry-syscall-return-view-seed-ready
runtime_entry_syscall_dispatch_view_status=runtime-entry-syscall-dispatch-view-seed-ready
runtime_entry_syscall_gate_view_status=runtime-entry-syscall-gate-view-seed-ready
runtime_entry_privilege_level_view_status=runtime-entry-privilege-level-view-seed-ready
```

It also keeps scheduler-return observation authority explicitly denied:

```text
runtime_entry_scheduler_return_observation_view_allowed=0
runtime_entry_post_resume_observation_view_allowed=0
runtime_entry_user_mode_resume_view_allowed=0
runtime_entry_allowed=0
post_resume_observation_allowed=0
scheduler_return_observation_allowed=0
scheduler_return_allowed=0
scheduler_execution_allowed=0
scheduler_dispatch_allowed=0
scheduler_handoff_allowed=0
scheduler_activation_allowed=0
scheduler_run_entry_allowed=0
dispatch_allowed=0
context_switch_allowed=0
run_queue_mutation_allowed=0
instruction_pointer_read_allowed=0
stack_pointer_read_allowed=0
cpu_mode_read_allowed=0
hardware_effect_allowed=0
host_effect_allowed=0
no_effect=1
```

## Metadata Shape

The first declared scheduler-return-observation-view record is the kernel report process metadata:

```text
scheduler_return_observation_view[0].process_label=kernel-report-process-metadata
scheduler_return_observation_view[0].scheduler_return_observation_view_class=kernel-report-runtime-entry-scheduler-return-observation-view
scheduler_return_observation_view[0].scheduler_return_observation_view_token=0
scheduler_return_observation_view[0].post_resume_observation_view_token=0
scheduler_return_observation_view[0].resume_slot=4096
scheduler_return_observation_view[0].observation_slot=5120
scheduler_return_observation_view[0].scheduler_return_slot=6144
scheduler_return_observation_view[0].scheduler_return_epoch_slot=17
scheduler_return_observation_view[0].scheduler_return_reason_slot=18
```

Those fields are declaration metadata only. They do not return from a
scheduler, observe a running scheduler, dispatch work, perform a context
switch, mutate a run queue, read live instruction pointers, read live stacks,
observe a running CPU mode, or touch hardware or host state.

## Boundary

This slice adds a deterministic metadata point after runtime-entry
post-resume observation while preserving the denial of scheduler-return
observation, scheduler returns, scheduler execution, scheduler dispatch,
context switching, run queue mutation, instruction pointer reads, stack pointer
reads, CPU mode reads, runtime entry, hardware effects, and host effects.

## Validation

```sh
sh scripts/test-kernel-runtime-entry-scheduler-return-observation-view.sh
sh scripts/test-kernel-runtime-entry-scheduler-return-observation-view-report-runner.sh
```

Expected output:

```text
kernel_runtime_entry_scheduler_return_observation_view: ok
kernel_runtime_entry_scheduler_return_observation_view_report_runner: ok
```
