# Kernel Seed Implementation

Status: first kernel implementation surface
Scope: compiled no-effect kernel seed, deterministic kernel report, and operator-facing report runner.

## Purpose

This slice creates the first Latticra kernel surface.

The kernel seed is not a bootable kernel. It is a compiled C interface that owns kernel identity, kernel status labels, subsystem status labels, and a deterministic kernel report while coordinating the already merged system bootstrap surface.

This is the next system-building step after `SYSTEM_BOOTSTRAP_IMPLEMENTATION.md`.

## Public API

```

## Kernel report fields

The deterministic report emits:

```text
LATTICRA KERNEL REPORT
kernel_id
kernel_mode
kernel_status
boot_status
runtime_status
scheduler_status
memory_status
process_status
filesystem_status
network_status
device_status
security_status
bootstrap_status
bootstrap_runtime_entry_status
bootstrap_no_effect
no_effect
execution_allowed
mutation_allowed
file_io_allowed
network_allowed
server_allowed
recovery_allowed
hardware_allowed
boot_allowed
evidence_level
source_identity
```

## Current kernel posture

The kernel seed reports:

```text
kernel_mode=seed-kernel
kernel_status=initialized-report-only
boot_status=not-booted
runtime_status=not-entered
scheduler_status=not-started
memory_status=metadata-only
process_status=not-started
filesystem_status=disabled
network_status=disabled
device_status=disabled
security_status=not-production-boundary
no_effect=1
```

## Validation

Run:

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

The guards compile the kernel seed, verify no-effect invariants, render the deterministic kernel report, and verify stable report fields.

## Boundary

This implementation does not add a bootloader, bootable image, hardware control, interrupts, paging, scheduler execution, process execution, system calls, filesystem I/O, network I/O, mutation, server interaction, recovery behavior, sandboxing, malware prevention, ransomware prevention, production security boundary, or operating-system replacement.

It is the first compiled kernel identity and report surface.
