# Production Installer Transcript Status Contract

Status: no-effect installer transcript status contract
Evidence level: 10 target, status evidence only
Scope: install, uninstall, and post-removal absence transcript status for future production-installer artifacts without installing, uninstalling, upgrading, rollback, package-manager invocation, network access, or host mutation.

## Purpose

The production-installer readiness contract requires reviewed install and uninstall transcripts, plus post-removal absence verification, 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 production-installer transcript evidence.

This contract adds a no-effect status command that records the missing production-installer transcript evidence and keeps every production readiness claim closed. It is paired with a no-effect transcript evidence intake validator for future reviewed dry-run transcript evidence bundles.

## Status command

```sh
sh scripts/production-installer-transcript-status.sh
```

## Required prerequisite records

The installer transcript status binds these prerequisite records:

```text
local_artifact_manifest_fixture_required=1
local_artifact_manifest_fixture_present=1
production_installer_preflight_guard_present=1
installer_install_plan_preview_present=1
production_installer_release_artifact_promotion_gate_present=1
production_installer_sbom_status_present=1
```

## Required status report fields

Every installer transcript status report must include:

```text
LATTICRA PRODUCTION INSTALLER TRANSCRIPT STATUS
status_version=1
status_mode=no-effect-installer-transcript-status
production_installer_transcript_status_present=1
installer_transcript_status_present=1
installer_install_transcript_status_present=1
installer_uninstall_transcript_status_present=1
installer_post_removal_absence_status_present=1
installer_transcript_status_no_effect=1
install_transcript_path=<recorded>

```

## Current readiness classification

This slice adds transcript status evidence only:

```text
production_installer_transcript_status_present=1
installer_transcript_status_present=1
installer_install_transcript_status_present=1
installer_uninstall_transcript_status_present=1
installer_post_removal_absence_status_present=1
installer_transcript_status_no_effect=1
install_transcript_present=0
uninstall_transcript_present=0
post_removal_absence_transcript_present=0
transcript_evidence_intake_validator_present=1
transcript_evidence_intake_validation_mode=no-effect-validation
transcript_evidence_candidate_valid=0
install_transcript_file_present=0
uninstall_transcript_file_present=0
post_removal_absence_transcript_file_present=0
install_transcript_sha256_recorded=0
uninstall_transcript_sha256_recorded=0
post_removal_absence_transcript_sha256_recorded=0
install_transcript_review_present=0
uninstall_transcript_review_present=0
post_removal_absence_review_present=0
transcript_evidence_accepted_by_intake_validator=0
transcript_evidence_written_by_intake_validator=0
installer_transcript_promotion_allowed_by_intake_validator_alone=0
installer_install_transcript_recorded=0
installer_uninstall_transcript_recorded=0
installer_post_removal_absence_verified=0
production_installer_ready=0
```

It does not install, uninstall, invoke a package manager, verify absence on a host, write transcripts, or validate production installer behavior.

## Required transcript promotion evidence

Before any transcript readiness flag can become `1`, a future lane must provide:

```text
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
```

## Guard validation

This contract is guarded by:

```sh
sh scripts/test-production-installer-transcript-status-contract.sh
```

Expected output:

```text
production_installer_transcript_status_contract: ok
```

## Next implementation lane

```text
Run a disposable Fedora VM production-installer dry-run and attach reviewed install, uninstall, and post-removal absence transcript evidence.
Validate install, uninstall, post-removal absence, and transcript-review evidence with the transcript 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 install evidence, not uninstall evidence, not post-removal absence verification, not upgrade validation, not rollback validation, 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.
