# Latticra Seal Runtime Dry-Run Report Surface

Status: report surface for the Latticra Seal runtime dry-run metadata layer
Scope: deterministic local report surface after the no-effect runtime dry-run metadata implementation. This document does not implement runtime behavior, runtime execution, runtime authority, effect execution, policy enforcement, capability enforcement, cryptographic verification, signature verification, freshness validation, replay detection, tool execution, AI agent execution, model execution, MCP protocol behavior, MCP server behavior, MCP client behavior, host reads, host writes, network behavior, operating-system behavior, production readiness, external endorsement, or authority grants.

## Purpose

This document records the first operator-visible report surface for Latticra Seal runtime dry-run metadata.

The report surface renders what the dry-run layer would deny without executing tools, touching host state, using the network, or granting authority.

## Added files

```text
tests/seal_runtime_dry_run_report_surface.c
scripts/latticra-seal-runtime-dry-run-report.sh
```

## Report runner

```sh
sh scripts/latticra-seal-runtime-dry-run-report.sh
```

## Expected report posture

The report surface renders the current dry-run posture, including:

```text
LATTICRA SEAL RUNTIME DRY RUN
runtime_dry_run_profile=latticra-seal-runtime-dry-run/0.1
request_class=core-blocked-request
policy_decision_state=report-only
runtime_gate_state=report-only
blocked_reason=default-deny-dry-run
dry_run_supported=1
dry_run_performed=1
input_policy_decision_present=1
input_runtime_gate_present=1

invalid_schema_denied=1
stale_request_denied=1
replayed_request_denied=1
invalid_signature_denied=1
report_only=1
mode=report-only
status=runtime-dry-run-metadata
```

## Boundary

This report surface compiles and runs a local deterministic fixture only.

It does not execute tools, execute shell commands, read host files, write host files, use the network, evaluate external policies, load policy files, verify signatures, validate freshness against live time, mutate replay caches, grant authority, claim production readiness, claim AI-agent security, or claim MCP implementation.

## Validation

Run:

```sh
sh scripts/test-latticra-seal-runtime-dry-run-report-surface.sh
```

Expected output:

```text
latticra seal runtime dry-run report surface: ok
```

The underlying runtime dry-run implementation remains covered by:

```sh
sh scripts/test-latticra-seal-runtime-dry-run.sh
```

## Claim boundary

This report surface does not justify the public claim that Latticra secures AI agents.

It makes the dry-run denial posture easier to inspect before any future runtime enforcement path is considered.

## Next valid slice

The next valid Latticra Seal slice is runtime dry-run report status alignment.

That future slice must preserve the no-effect posture and must not perform effects or grant authority.
