Before you ship

Check the runtime and version, integration limits, dependencies and licenses, and platform support. Verify security, failure, speed, monitoring, deploy, support owner, upgrade path, and rollback.

Outcome: Use or review HTML as a technical building block that the team can maintain. User context: A developer marks an article's heading, navigation, publish time, and figure with the right HTML elements. The page has a useful structure before CSS or JavaScript loads. HTML gives content structure and meaning, not its visual style. Technology or engineering concept: HTML. Why it fits: Use this term for a web page's structure, built-in controls, page information, or meaningful elements. Do not use it when: Do not use HTML as another name for CSS, JavaScript, or all frontend technology. Engineering fit: Define where it runs and which version to use. Set its job, interfaces, data flow, dependencies, supported systems, security, and speed limits. Explain how it fits the current stack. Lifecycle safeguards: Check dependency health and licenses. Add monitoring and a fallback. Name the upgrade owner. Do not add a second tool for the same job without a measured benefit. Acceptance criteria: A small integration proves the needed behavior. Test compatibility, security, failure, and performance. Document deploy, upgrade, support, and rollback steps. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Current stack, runtime and version rules, target systems, dependency owner, performance budget, support period, and migration limits.

Check this request

Review the current use of HTML. Definition: HTML is the standard markup language that gives a web page its parts and meaning. It tells the browser what is a heading, link, image, form, and more. Release checks: Check the runtime and version, integration limits, dependencies and licenses, and platform support. Verify security, failure, speed, monitoring, deploy, support owner, upgrade path, and rollback. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
