# Latticra Seal Crypto Verify Backend Status

Status: status record for the Latticra Seal crypto verify backend readiness surface
Source: local follow-up slice
Scope: status and public-entry alignment after the Seal crypto verify backend contract and readiness implementation. This record does not perform signature verification itself, signing, key generation, private-key storage, public-key trust stores, network trust lookup, revocation lookup, object sealing, capability enforcement, runtime authority, host reads, host writes, kernel behavior, Fedora approval claims, production readiness, or operating-system behavior.

## Purpose

This status record makes the Latticra Seal crypto verify backend readiness layer visible from public entry points.

The backend layer is important because it records the local Ed25519 verification backend as ready without treating readiness metadata as authority.

It remains verification-not-performed, authority-neutral, and no-effect.

## Validation

This status surface is covered by:

```sh
sh scripts/test-latticra-seal-crypto-verify-backend-status.sh
```

The underlying readiness implementation remains covered by:

```sh
sh scripts/test-latticra-seal-crypto-verify-backend.sh
```

Expected output:

```text
seal crypto verify backend status: ok
seal crypto verify backend invariants: ok
```

## Boundary

This status record is documentation/status alignment for the backend readiness boundary.

It does not perform signature verification in the backend, signing, key generation, private-key handling, trust-store behavior, revocation lookup, object sealing, capability enforcement, effect execution, runtime behavior, host behavior, network behavior, production readiness, external endorsement, or authority grants.

## Current next valid slice

No completion-estimate review is required from this documentation/status-only alignment.

The next valid Latticra Seal slice is Ed25519 verify-only implementation status/public-entry alignment or another narrow status/index alignment follow-up.
