# Latticra Panel Signed Updater Manifest Fixture Validation

Status: local no-effect signed updater manifest fixture validation
Date: 2026-05-26 CDT
Scope: validation for the committed Latticra Panel signed-updater manifest fixture.

## Purpose

This slice validates the committed manifest fixture shape without making the fixture trusted signed update evidence.

The validator reads only the local fixture, checks the expected schema and closed-authority fields, and reports that the fixture is valid only as no-effect input for future updater design work.

```text
signed_updater_manifest_fixture_validation_present=1
signed_updater_manifest_fixture_validated=1
signed_updater_manifest_fixture_validation_scope=shape-and-closed-authority-fields
manifest_fixture_trusted_for_apply=0
signed_updater_manifest_fixture_valid_for_apply=0
trusted_signed_manifest_present=0
signed_update_apply_allowed=0
```

## Command

```sh
sh scripts/latticra-panel-signed-updater-manifest-fixture-validation.sh
```

The command reads:

```text
fixtures/latticra-panel/signed-updater-manifest.fixture.toml
```

It writes only a deterministic report to stdout.

## Validation Boundary

The validator checks local fixture shape:

```text
manifest_schema_validated=1
manifest_fixture_flag_validated=1
manifest_fixture_scope_validated=1
manifest_fixture_effect_validated=1
local_checkout_strategy_validated=1
closed_authority_fields_validated=1
non_claims_validated=1
```

The validator does not verify a real signed update:

```text
signed_manifest_present=0
manifest_signature_verified=0
artifact_hash_verified=0
artifact_signature_verified=0
rollback_plan_present=0
operator_confirmation_observed=0
update_receipt_written=0
```

The authority boundary remains closed:

```text
network_fetch_authority=0
network_fetch_attempted=0
remote_update_repository_trust=0
staged_update_performed=0
signed_update_apply_performed=0
validation_write_performed=0
host_mutation_performed=0
root_authority=0
production_update_ready=0
```

## Validation

This slice is guarded by:

```sh
sh scripts/test-latticra-panel-signed-updater-manifest-fixture-validation.sh
```

Expected output:

```text
latticra_panel_signed_updater_manifest_fixture_validation: ok
```

## Next Recommended Lane

```text
Add Panel signed-updater state transition denial disposition closeout audit review disposition review closeout without enabling transition execution or update apply.
```

## Non-Claims

This validation is not signed update evidence, network update evidence, update-server evidence, trusted repository evidence, artifact-verification evidence, rollback evidence, receipt evidence, production update readiness, production installer readiness, root installer readiness, kernel integration, systemd integration, SELinux integration, runtime enforcement, malware prevention, ransomware prevention, sandboxing, or a production security-product claim.
