[dependabot]

Bumps js-yaml from 4.1.0 to 4.3.0.

Changelog

Sourced from js-yaml's changelog.

4.3.0, 3.15.0 - 2026-06-27

Security

• Backported maxTotalMergeKeys option.

[5.2.0] - 2026-06-26

Added

• Added maxTotalMergeKeys (10000) loader option to limit the total number of keys processed by YAML merge (<<) across one load() / loadAll() call.
• Added maxAliases (-1) loader option to limit the number of YAML aliases per document.

Removed

• maxMergeSeqLength replaced with maxTotalMergeKeys for limiting YAML merge processing.

Fixed

• Round-trip of integers with exponential form (>= 1e21)

[5.1.0] - 2026-06-23

Added

• Collection tags can finalize an incrementally populated carrier into a different result value.

Changed

• [breaking] quoteStyle now selects the preferred quote style; use the restored forceQuotes option to force quoting non-key strings.

[5.0.0] - 2026-06-20

Added

• Added named exports for schemas, tags, parser events and AST utilities.
• Reworked JSON_SCHEMA and CORE_SCHEMA with spec-compliant scalar resolution rules, and added YAML11_SCHEMA.
• Added realMapTag for lossless mappings with non-string and complex keys. Object-based mappings now reject complex keys instead of stringifying them.
• Added dump() transform option for changing the generated AST before rendering.
• Added dump() options seqInlineFirst, flowBracketPadding, flowSkipCommaSpace, flowSkipColonSpace, quoteFlowKeys, quoteStyle and tagBeforeAnchor.
• Added formal data layers (events and AST) for modular data pipelines.
  • Added low-level parser (to events), presenter and visitor APIs.
• Added the YAML Test Suite to the test set.

Changed

• See the migration guide for upgrade notes.
• Rewritten in TypeScript and reorganized the public API around flat named exports.

Pull Request Overview

This PR is currently out of sync: while package-lock.json has been updated to js-yaml version 4.3.0, the package.json manifest was not included in the changes. This creates a discrepancy that will likely lead to build or deployment inconsistencies. Additionally, the move to version 4.3.0 includes breaking changes to the library's API—specifically the replacement of maxMergeSeqLength with maxTotalMergeKeys. These structural and functional gaps should be addressed before merging.

About this PR

• The PR updates package-lock.json but omits package.json. This results in a manifest/lockfile mismatch. Please include the package.json change in this PR.
• Check the codebase for any usage of the maxMergeSeqLength option in js-yaml loader calls. This option has been removed and replaced by maxTotalMergeKeys. If currently in use, it must be updated to prevent breakage.

Test suggestions

• Verify that the js-yaml version is incremented to 4.3.0 in package.json
• Confirm that YAML parsing functionality remains stable after the dependency update

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that the js-yaml version is incremented to 4.3.0 in package.json
2. Confirm that YAML parsing functionality remains stable after the dependency update
