Slate Validation Engine

slate-validation-engine is the public-facing runtime and adapter package for Slate. It is meant to stand alone as a small, inspectable command-line distribution, AppKit adapter surface, fixture set, and contract package for validating Apple movie package metadata.

This repository skeleton is intentionally narrow:

• documented public runtime and CLI behavior
• documented public Slate.app Apple Events
• public Slate.app adapter source that calls sibling runtimes
• public paneharness proof target
• machine-readable report contracts
• tiny public fixtures
• examples and golden outputs

It does not include private validation engine internals, package normalization logic, track classification logic, chapter/timecode reasoning, review intelligence, private media, or private Git history.

Current Status

This directory is the reviewed public package prepared inside the private Slate worktree. It carries only the public runtime surface: docs, schemas, fixtures, examples, public adapter source, proof harness source, and intentional runtime deliverables.

Quick Start

tools/verify_public_package.sh
tools/verify_runtime_manifest.sh
./Runtime/slate report --package fixtures/media_pkg/valid/source-basic.itmsp/metadata.xml
./Runtime/slate analyze fixtures/media_json/valid/source-basic.json
./Runtime/slate readiness -p fixtures/media_pkg/invalid/source-missing-path.itmsp/metadata.xml
fixtures/verify_golden.sh
cd slate-application && ./build_public_apps.sh

See docs/apple-events.md for the public Slate.app and paneharness.app Apple Event surface.

The golden outputs normalize the absolute checkout path to <repo> so results can be reviewed from any clone location.

The public application build writes local products to slate-application/build/Release. That build directory is ignored and is not part of the public package history. Runtime executables live in slate-application/Runtime; the Xcode targets copy them beside Slate.app and paneharness.app during local builds.

Public Preview Usage Cap

The public preview Runtime/slate binary is limited to 60 validation runs: 20 analyze, 20 report, and 20 readiness calls. Help and usage failures do not consume the preview ledger.

When the preview limit is reached, analyze and report return a parseable slate.validationUsageError.v1 JSON object and exit 68. readiness returns a plain operator message and exits 68. A corrupt or tampered preview ledger also fails closed with exit 68.
