# Production Installer Transcript Evidence Template Contract Status: no-effect transcript evidence template contract Evidence level: 10 target, template only Scope: print the required future production-installer dry-run transcript evidence bundle shape without installing, uninstalling, invoking package managers, calculating transcript hashes, writing evidence files, accepting evidence, passing promotion, using network access, or mutating the host. ## Purpose The transcript evidence intake validator can validate a complete future dry-run transcript evidence bundle, but the bundle still needs a stable, reviewable shape before a release operator can collect install, uninstall, post-removal absence, and review evidence safely. This contract records a no-effect stdout-only template for that future evidence bundle. It mirrors the validator's required fields and keeps placeholder digest values intentionally invalid until real dry-run transcript and review files exist. It does not write the evidence file and does not make a candidate valid. ## Command ```sh sh scripts/production-installer-transcript-evidence-template.sh ``` ## Current classification ```text transcript_evidence_template_present=1 transcript_evidence_template_mode=no-effect-template transcript_evidence_template_decision=blocked-template-only-no-evidence-write transcript_evidence_template_complete=0 transcript_evidence_intake_validator_present=1 transcript_evidence_intake_validation_mode=no-effect-validation install_transcript_file_present= uninstall_transcript_file_present= post_removal_absence_transcript_file_present= install_transcript_review_file_present= uninstall_transcript_review_file_present= post_removal_absence_review_file_present= transcripts_created_by_template=0 transcript_hashes_calculated_by_template=0 transcript_evidence_written_by_template=0 transcript_evidence_accepted_by_template=0 transcript_evidence_accepted_by_intake_validator=0 transcript_evidence_written_by_intake_validator=0 installer_transcript_promotion_allowed_by_intake_validator_alone=0 release_artifact_promotion_gate_passed=0 installer_install_transcript_recorded=0 installer_uninstall_transcript_recorded=0 installer_post_removal_absence_verified=0 install_performed=0 uninstall_performed=0 package_manager_invoked=0 network_allowed=0 host_mutation_performed=0 production_installer_ready=0 ``` ## Required transcript markers The template must print the marker blocks required in future transcript files: ```text LATTICRA PRODUCTION INSTALLER DRY RUN INSTALL TRANSCRIPT production_installer_dry_run_performed=1 install_transcript_present=1 install_performed=0 package_manager_invoked=0 host_mutation_performed=0 network_allowed=0 LATTICRA PRODUCTION INSTALLER DRY RUN UNINSTALL TRANSCRIPT production_installer_dry_run_performed=1 uninstall_transcript_present=1 uninstall_performed=0 package_manager_invoked=0 host_mutation_performed=0 network_allowed=0 LATTICRA PRODUCTION INSTALLER DRY RUN POST-REMOVAL ABSENCE TRANSCRIPT production_installer_dry_run_performed=1 post_removal_absence_transcript_present=1 post_removal_absence_check_performed=1 post_removal_absence_verified=1 host_mutation_performed=0 network_allowed=0 ``` ## Required evidence fields The template must print the same required field names that the intake validator expects: ```text LATTICRA PRODUCTION INSTALLER TRANSCRIPT EVIDENCE transcript_evidence_status=complete production_installer_dry_run_performed=1 install_transcript_present=1 uninstall_transcript_present=1 post_removal_absence_transcript_present=1 install_transcript_reviewed=1 uninstall_transcript_reviewed=1 post_removal_absence_reviewed=1 installer_install_transcript_recorded=1 installer_uninstall_transcript_recorded=1 installer_post_removal_absence_verified=1 install_transcript_sha256= uninstall_transcript_sha256= post_removal_absence_transcript_sha256= install_transcript_review_sha256= uninstall_transcript_review_sha256= post_removal_absence_review_sha256= install_performed=0 uninstall_performed=0 package_manager_invoked=0 release_artifact_promotion_gate_passed=0 production_installer_ready=0 fedora_distribution_ready=0 fedora_approval_claimed=0 daily_driver_install_ready=0 immutable_fedora_ready=0 host_mutation_performed=0 network_allowed=0 ``` The placeholders above must be replaced with real SHA-256 values before the evidence intake validator can pass. ## Required source records The template binds the current blocked transcript posture: ```text production_installer_ready=0 transcript_evidence_intake_validator_present=1 transcript_evidence_status=complete release_artifact_promotion_gate_passed=0 ``` ## Guard validation This contract is guarded by: ```sh sh scripts/test-production-installer-transcript-evidence-template-contract.sh ``` Expected output: ```text production_installer_transcript_evidence_template_contract: ok ``` ## Next implementation lane ```text Use the template after a disposable Fedora VM production-installer dry-run exists, fill real SHA-256 values from reviewed install, uninstall, post-removal absence, and review files, then validate the completed evidence bundle with the transcript evidence intake validator. ``` Production readiness must remain closed until every other production-installer readiness gate is also satisfied. ## Non-claims This template is not install evidence, not uninstall evidence, not post-removal absence evidence, not transcript evidence acceptance, not evidence writing, not package-manager execution, not host mutation, not release artifact evidence, not SBOM review, not artifact promotion, not upgrade validation, not rollback validation, not recovery validation, not multi-VM validation, not Fedora approval, not Fedora distribution readiness, not daily-driver readiness, not immutable Fedora readiness, and not production installer readiness.
