# Production Installer Recovery Failure Mode Status Contract

Status: no-effect installer recovery failure-mode status contract
Evidence level: 10 target, status evidence only
Scope: recovery runbook, failure-mode register, recovery drill, rollback drill, and operator recovery evidence status for future production-installer artifacts without installing, uninstalling, upgrading, rolling back, package-manager invocation, network access, or host mutation.

## Purpose

The production-installer readiness contract requires documented failure modes and a recovery runbook before Latticra can claim production installer readiness.

The current repository has no reviewed production-installer recovery runbook, failure-mode register, recovery drill transcript, rollback drill transcript, or operator recovery receipt.

This contract adds a no-effect status command that records those missing recovery and failure-mode evidence records while keeping every production readiness claim closed.

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

## Status command

```sh
sh scripts/production-installer-recovery-failure-mode-status.sh
```

## Required prerequisite records

The installer recovery failure-mode 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
```

## Required status report fields

Every installer recovery failure-mode status report must include:

```text

## Current readiness classification

This slice adds recovery and failure-mode status evidence only:

```text
production_installer_recovery_failure_mode_status_present=1
installer_failure_mode_status_present=1
installer_recovery_runbook_status_present=1
installer_recovery_drill_status_present=1

recovery_runbook_present=0
failure_mode_register_present=0
recovery_drill_transcript_present=0
rollback_drill_transcript_present=0
operator_recovery_receipt_present=0
recovery_runbook_reviewed=0
failure_mode_register_reviewed=0
recovery_drill_reviewed=0
rollback_drill_reviewed=0
operator_recovery_receipt_reviewed=0
recovery_evidence_intake_validator_present=1
recovery_evidence_intake_validation_mode=no-effect-validation

host_mutation_performed=0
production_installer_ready=0
fedora_distribution_ready=0
fedora_approval_claimed=0
daily_driver_install_ready=0
immutable_fedora_ready=0
```

It does not install, uninstall, upgrade, rollback, recover a host, invoke a package manager, write transcripts, mutate a host, or validate production installer recovery behavior.

## Required recovery promotion evidence

Before any recovery or failure-mode readiness flag can become `1`, a future lane must provide:

```text
recovery_runbook_present=1
failure_mode_register_present=1
recovery_drill_transcript_present=1
rollback_drill_transcript_present=1
operator_recovery_receipt_present=1
recovery_runbook_reviewed=1
failure_mode_register_reviewed=1
recovery_drill_reviewed=1
rollback_drill_reviewed=1
operator_recovery_receipt_reviewed=1
installer_failure_mode_documented=1
installer_recovery_runbook_present=1
installer_recovery_runbook_reviewed=1
installer_recovery_drill_validated=1
installer_rollback_drill_validated=1
installer_failure_mode_evidence_recorded=1
```

## Guard validation

This contract is guarded by:

```sh
sh scripts/test-production-installer-recovery-failure-mode-status-contract.sh
```

Expected output:

```text
production_installer_recovery_failure_mode_status_contract: ok
```

## Next implementation lane

```text
Create and review the production-installer recovery runbook, failure-mode register, recovery drill transcript, rollback drill transcript, and operator recovery receipt.
Validate recovery runbook, failure-mode register, recovery drill, rollback drill, operator receipt, and review evidence with the recovery 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 recovery evidence, not failure-mode evidence, not recovery safety, not rollback safety, not install evidence, not uninstall 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.
