Validator Core 0.3.0

Added

• validateGddValue() checks supplied data with exact paths and explicitly reports unsupported assertions without adding runtime dependencies.
• A read-only spec:check:upstream command and independent weekly GitHub workflow compare the pinned specification sources with EBU main.

Changed

• Update the pinned EBU snapshot to 8a74757b (22 September 2026), including the action-schema example annotation and corrected reference manifests. Graphics requirements and validation rules are unchanged.
• Restore the original UTF-8 author name in the logo reference manifest, correcting an encoding error in the previous local copy.
• Clarify that spec:check verifies local consistency without checking upstream freshness.

Fixed

• Schema diagnostics select the applicable action-duration branch, omit redundant conditional summaries, and preserve contextual corrections.
• Present null fields are diagnosed by type instead of being reported as missing.
• Unusual module extensions and defaults that violate data constraints are warnings, while explicit EBU default-type restrictions remain errors.

OGraf Validator App 0.2.4

Fixed

• Diagnose runtime failures from structured check metadata instead of matching words in Graphic errors; distinguish EmptyPayload, status fields, steps, exports, and Promise contracts.
• Bound test-data generation, validate generated input before invoking Graphics, exercise parameterless custom actions, and mark incomplete checks as inconclusive.
• Capture uncaught runtime errors through cleanup and check the expected first step when the manifest declares a known step count.
• Validate manual schedule parameter shapes and declared custom-action IDs before dispatch.
• Update indirect development dependencies brace-expansion and fast-uri to resolve the release audit findings.

Added

• Consistent diagnostic guidance and official specification references in the UI, clipboard output, and JSON/HTML reports.
• Browser regressions for runtime diagnostics, input gaps, cleanup failures, exports, and the versioned sandbox handshake.

OGraf Validator Core 0.2.1

Added

• Machine-readable metadata for the vendored EBU OGraf specification snapshot.
• Release checks that keep the snapshot directory, upstream commit, documentation, checksums, generated validator, and packaged files in sync.
• Regression tests for malformed snapshot metadata, stale documentation, and unsafe or duplicate checksum paths.

Changed

• Validator generation, snapshot tests, and the npm package smoke test now discover the active snapshot from its metadata instead of using a hardcoded directory.

See the Validator Core changelog for details.
