# Production Installer Lifecycle Validation Status Contract Status: no-effect installer lifecycle validation status contract Evidence level: 10 target, status evidence only Scope: upgrade, rollback, downgrade, and reinstall-idempotence validation status for future production-installer artifacts without installing, upgrading, downgrading, rollback, reinstalling, package-manager invocation, network access, or host mutation. ## Purpose The production-installer readiness contract requires upgrade validation, rollback or downgrade validation, and reinstall idempotence validation before Latticra can claim production installer readiness. The current repository records no production-installer install or uninstall transcript. Without those prerequisites, upgrade, rollback, and reinstall idempotence evidence cannot be accepted. This contract adds a no-effect status command that records the missing production-installer lifecycle validation evidence and keeps every production readiness claim closed. It is paired with a no-effect lifecycle evidence intake validator for future reviewed lifecycle transcript evidence bundles. ## Status command ```sh sh scripts/production-installer-lifecycle-validation-status.sh ``` ## Required prerequisite records The installer lifecycle validation status binds these prerequisite records: ```text production_installer_transcript_status_present=1 installer_install_transcript_recorded=0 installer_uninstall_transcript_recorded=0 installer_post_removal_absence_verified=0 production_installer_release_artifact_promotion_gate_present=1 production_installer_sbom_status_present=1 ``` ## Required status report fields Every installer lifecycle validation status report must include: ```text LATTICRA PRODUCTION INSTALLER LIFECYCLE VALIDATION STATUS status_version=1 status_mode=no-effect-installer-lifecycle-validation-status production_installer_lifecycle_validation_status_present=1 installer_upgrade_status_present=1 installer_rollback_status_present=1 installer_reinstall_idempotence_status_present=1 installer_lifecycle_validation_status_no_effect=1 installer_upgrade_candidate_present=0 installer_rollback_candidate_present=0 installer_reinstall_candidate_present=0 upgrade_transcript_present=0 rollback_transcript_present=0 reinstall_transcript_present=0 upgrade_transcript_reviewed=0 rollback_transcript_reviewed=0 reinstall_transcript_reviewed=0 lifecycle_evidence_intake_validator_present=1 lifecycle_evidence_intake_validation_mode=no-effect-validation lifecycle_evidence_candidate_valid=0 upgrade_transcript_file_present=0 rollback_transcript_file_present=0 reinstall_transcript_file_present=0 upgrade_transcript_sha256_recorded=0 rollback_transcript_sha256_recorded=0 reinstall_transcript_sha256_recorded=0 upgrade_transcript_review_present=0 rollback_transcript_review_present=0 reinstall_transcript_review_present=0 lifecycle_evidence_accepted_by_intake_validator=0 lifecycle_evidence_written_by_intake_validator=0 installer_lifecycle_promotion_allowed_by_intake_validator_alone=0 installer_upgrade_path_validated=0 installer_rollback_path_validated=0 installer_downgrade_or_rollback_path_validated=0 installer_reinstall_idempotence_validated=0 production_installer_lifecycle_validation_performed=0 upgrade_performed=0 rollback_performed=0 reinstall_performed=0 package_manager_invoked=0 host_mutation_performed=0 network_allowed=0 production_installer_ready=0 ``` ## Current readiness classification This slice adds lifecycle validation status evidence only: ```text production_installer_lifecycle_validation_status_present=1 installer_upgrade_status_present=1 installer_rollback_status_present=1 installer_reinstall_idempotence_status_present=1 installer_lifecycle_validation_status_no_effect=1 upgrade_transcript_present=0 rollback_transcript_present=0 reinstall_transcript_present=0 lifecycle_evidence_intake_validator_present=1 lifecycle_evidence_intake_validation_mode=no-effect-validation lifecycle_evidence_candidate_valid=0 upgrade_transcript_file_present=0 rollback_transcript_file_present=0 reinstall_transcript_file_present=0 upgrade_transcript_sha256_recorded=0 rollback_transcript_sha256_recorded=0 reinstall_transcript_sha256_recorded=0 upgrade_transcript_review_present=0 rollback_transcript_review_present=0 reinstall_transcript_review_present=0 lifecycle_evidence_accepted_by_intake_validator=0 lifecycle_evidence_written_by_intake_validator=0 installer_lifecycle_promotion_allowed_by_intake_validator_alone=0 installer_upgrade_path_validated=0 installer_rollback_path_validated=0 installer_downgrade_or_rollback_path_validated=0 installer_reinstall_idempotence_validated=0 production_installer_ready=0 ``` It does not install, upgrade, downgrade, rollback, reinstall, invoke a package manager, write transcripts, mutate a host, or validate production installer lifecycle behavior. ## Required lifecycle promotion evidence Before any lifecycle validation readiness flag can become `1`, a future lane must provide: ```text production_installer_lifecycle_validation_performed=1 installer_upgrade_candidate_present=1 installer_rollback_candidate_present=1 installer_reinstall_candidate_present=1 upgrade_transcript_present=1 rollback_transcript_present=1 reinstall_transcript_present=1 upgrade_transcript_reviewed=1 rollback_transcript_reviewed=1 reinstall_transcript_reviewed=1 installer_upgrade_path_validated=1 installer_rollback_path_validated=1 installer_downgrade_or_rollback_path_validated=1 installer_reinstall_idempotence_validated=1 ``` ## Guard validation This contract is guarded by: ```sh sh scripts/test-production-installer-lifecycle-validation-status-contract.sh ``` Expected output: ```text production_installer_lifecycle_validation_status_contract: ok ``` ## Next implementation lane ```text Attach reviewed upgrade, rollback, and reinstall idempotence transcripts from disposable Fedora VM production-installer lifecycle validation. Validate upgrade, rollback, reinstall idempotence, and lifecycle-review evidence with the lifecycle 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 upgrade evidence, not rollback evidence, not downgrade evidence, not reinstall idempotence evidence, 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.
