# Latticra Panel Signed Updater State Fixture Contract

Status: local no-effect signed updater state fixture contract
Date: 2026-05-26 CDT
Scope: local state fixture contract for future signed updater state work behind the Latticra Panel updater.

## Purpose

This slice adds a committed local state fixture for the Panel signed updater lane.

The fixture gives the closed delivery gate a state-shaped record to review without enabling state transitions, staging, activation, rollback execution, receipt writes, or signed update apply.

```text
signed_updater_state_fixture_contract_present=1
signed_updater_state_fixture_present=1
state_fixture_effect=none
current_update_state=blocked
state_transition_execution_allowed=0
signed_update_apply_allowed=0
```

## Fixture

The fixture lives at:

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

It records the planned state names while keeping the current fixture state blocked:

```text
available
downloaded
verified
staged
armed
applied
rolled_back
failed
blocked
current_update_state=blocked
requested_update_state=blocked
state_transition_decision=deny-transition
```

## Command

```sh
sh scripts/latticra-panel-signed-updater-state-fixture-contract.sh
```

The command writes only a deterministic report to stdout.

## Authority Boundary

The state fixture is explicitly not executable:

```text
state_transition_execution_allowed=0
state_transition_execution_performed=0
state_receipt_written=0
staged_state_materialized=0
armed_state_materialized=0
applied_state_materialized=0
rollback_execution_allowed=0
update_activation_allowed=0
signed_update_apply_allowed=0
```

The signed updater boundary remains closed:

```text
trusted_signed_manifest_present=0
manifest_signature_verified=0
artifact_hash_verified=0
artifact_signature_verified=0
rollback_plan_present=0
operator_confirmation_observed=0
network_fetch_attempted=0
host_mutation_performed=0
production_update_ready=0
```

## Validation

This contract is guarded by:

```sh
sh scripts/test-latticra-panel-signed-updater-state-fixture-contract.sh
```

Expected output:

```text
latticra_panel_signed_updater_state_fixture_contract: 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 update-state evidence, state-transition execution, 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.
