# Latticra Panel Signed Updater Delivery Gate

Status: no-effect signed updater delivery gate
Date: 2026-05-26 CDT
Scope: closed gate for any future signed, network-delivered update path behind the Latticra Panel updater.

## Purpose

The current Latticra Panel updater is a guarded local-checkout lane. It reuses the installer engine, requires preview before apply, and keeps network fetch authority disabled.

This contract defines the gate that must stay closed before any future signed or network-delivered updater can exist:

```text
signed_updater_delivery_gate_state=closed
signed_update_delivery_ready=0
network_self_update_ready=0
signed_update_apply_allowed=0
```

## Command

```sh
sh scripts/latticra-panel-signed-updater-delivery-gate.sh
```

The command writes only a deterministic report to stdout.

## Current Gate Decision

The current gate decision is:

```text
signed_updater_delivery_gate_decision=blocked-missing-signed-manifest-artifact-verification-and-rollback-evidence
```

The gate stays closed because these required future pieces are absent:

```text
signed_manifest_present=0
manifest_signature_verified=0
artifact_hash_verified=0
artifact_signature_verified=0
channel_policy_present=0
compatibility_policy_present=0
rollback_plan_present=0
rollback_evidence_present=0
post_update_validation_present=0
operator_confirmation_observed=0
update_receipt_written=0
```

## Required Preconditions

Before a signed update may ever be staged or applied, a later implementation must provide all of:

```text
signed_manifest_required=1
manifest_signature_required=1
artifact_hash_required=1
artifact_signature_required=1
channel_policy_required=1
compatibility_policy_required=1
rollback_plan_required=1
post_update_validation_required=1
operator_confirmation_required=1
update_receipt_required=1
```

## Authority Boundary

The current authority boundary remains:

```text
remote_update_repository_trust=0
network_fetch_authority=0
updater_network_fetch_enabled=0
staged_update_allowed=0
signed_update_apply_allowed=0
update_activation_allowed=0
host_mutation_allowed=0
host_mutation_performed=0
root_authority=0
system_mutation_authority=0
kernel_mutation_authority=0
systemd_mutation_authority=0
selinux_mutation_authority=0
boot_mutation_authority=0
production_update_ready=0
```

## Validation

This contract is guarded by:

```sh
sh scripts/test-latticra-panel-signed-updater-delivery-gate.sh
```

Expected output:

```text
latticra_panel_signed_updater_delivery_gate: 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 contract is not a signed updater, network updater, update server, remote repository trust policy, artifact verifier, rollback implementation, production update path, production installer, root installer, host mutation permission, boot integration, kernel integration, systemd integration, SELinux integration, malware prevention, ransomware prevention, sandbox, or production security-product claim.
