# Latticra Seal Ed25519 Verify Status

Status: status record for the Latticra Seal Ed25519 verify-only result surface
Source: local follow-up slice
Scope: status and public-entry alignment after the Seal Ed25519 verify-only contract and local implementation. This record does not add 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 local Ed25519 verify-only implementation visible from public entry points.

The verify-only layer is important because it is the first local cryptographic operation in the Seal lane, while still refusing to treat a successful verification result as authority by itself.

## Validation

This status surface is covered by:

```sh
sh scripts/test-latticra-seal-ed25519-verify-status.sh
```

The underlying implementation remains covered by:

```sh
sh scripts/test-latticra-seal-ed25519-verify.sh
```

Expected output:

```text
seal ed25519 verify status: ok
seal ed25519 verify invariants: ok
```

## Boundary

This status record is documentation/status alignment only.

The local Ed25519 verify-only implementation verifies caller-provided message, public-key, and signature bytes through OpenSSL EVP, but a successful result remains authority-neutral.

It does not add 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 status/public-entry alignment.

The next valid Latticra Seal slice is verified receipt promotion status/public-entry alignment or another narrow status/index alignment follow-up.
