# Production Installer Multi-VM Validation Status Contract

Status: no-effect installer multi-VM validation status contract
Evidence level: 10 target, status evidence only
Scope: fresh disposable Fedora VM, repeat disposable Fedora VM, existing-install upgrade, remove-and-reinstall, unsupported-target block, non-root CLI use, root-boundary, checksum verification, and package-signature verification status for future production-installer artifacts without running VMs, installing, uninstalling, upgrading, rolling back, package-manager invocation, network access, or host mutation.

## Purpose

The production-installer readiness contract requires multi-VM validation before Latticra can claim production installer readiness.

The current repository has disposable Fedora VM evidence for the bounded no-effect CLI payload. That is still not multi-VM production-installer validation evidence.

This contract adds a no-effect status command that records the missing multi-VM validation evidence and keeps every production readiness claim closed.

The paired multi-VM evidence intake validator is present as a no-effect checker for future reviewed multi-VM evidence bundles. It does not accept evidence, pass promotion, run VMs, or change the current multi-VM readiness flags.

## Status command

```sh
sh scripts/production-installer-multi-vm-validation-status.sh
```

## Required prerequisite records

The installer multi-VM validation status binds these prerequisite records:

```text
local_artifact_manifest_fixture_required=1
local_artifact_manifest_fixture_present=1
production_installer_transcript_status_present=1
production_installer_lifecycle_validation_status_present=1
production_installer_recovery_failure_mode_status_present=1
```

## Required status report fields

Every installer multi-VM validation status report must include:

```text

It does not run VMs, install, uninstall, upgrade, rollback, invoke a package manager, write transcripts, mutate a host, or validate production installer multi-VM behavior.

## Required multi-VM promotion evidence

Before any multi-VM readiness flag can become `1`, a future lane must provide:

```text
fresh_vm_validation_evidence_present=1
repeat_vm_validation_evidence_present=1
existing_install_validation_evidence_present=1
remove_reinstall_validation_evidence_present=1
unsupported_target_validation_evidence_present=1
non_root_cli_validation_evidence_present=1
root_boundary_validation_evidence_present=1
checksum_verification_evidence_present=1
package_signature_verification_evidence_present=1
fresh_vm_validation_reviewed=1
repeat_vm_validation_reviewed=1
existing_install_validation_reviewed=1
remove_reinstall_validation_reviewed=1
unsupported_target_validation_reviewed=1
non_root_cli_validation_reviewed=1
root_boundary_validation_reviewed=1
checksum_verification_reviewed=1
package_signature_verification_reviewed=1
fresh_disposable_fedora_vm_validation=1
repeat_disposable_fedora_vm_validation=1
existing_install_upgrade_validation=1
remove_and_reinstall_validation=1
unsupported_target_block_validation=1
non_root_cli_use_validation=1
root_boundary_validation=1
checksum_verification_validation=1
package_signature_verification_validation=1
installer_multi_vm_validation_completed=1
installer_fresh_vm_validation_completed=1
installer_repeat_vm_validation_completed=1
installer_existing_install_validation_completed=1
installer_non_root_cli_validation_completed=1
installer_root_boundary_validation_completed=1
```

## Guard validation

This contract is guarded by:

```sh
sh scripts/test-production-installer-multi-vm-validation-status-contract.sh
```

Expected output:

```text
production_installer_multi_vm_validation_status_contract: ok
```

## Next implementation lane

```text
Attach reviewed fresh VM, repeat VM, existing-install upgrade, remove-and-reinstall, unsupported-target block, non-root CLI, root-boundary, checksum verification, and package-signature verification evidence from disposable production-installer validation.
Validate fresh VM, repeat VM, existing-install upgrade, remove-and-reinstall, unsupported-target block, non-root CLI, root-boundary, checksum verification, package-signature verification, and review evidence with the multi-VM evidence intake validator.
```

That lane should preserve `production_installer_ready=0` unless every other production-installer readiness gate is also satisfied.

## Non-claims

This status record is not a production installer.

It is not multi-VM evidence, not install evidence, not uninstall evidence, not upgrade evidence, not rollback evidence, not recovery evidence, not package-manager execution, not host mutation, not release artifact evidence, not SBOM review, not Fedora approval, not Fedora distribution readiness, not daily-driver readiness, not immutable Fedora readiness, not security hardening, not malware prevention, not ransomware prevention, and not OS-replacement readiness.
