GPT-5.4 Prototype Docs

This is a documentation-focused packaging of the GPT-5.4 design pass.

Goals of this prototype:

• Keep Markdown as the readable source format
• Use stable heading anchors for cross-document links
• Add one machine-friendly JSON layer for AI and tooling
• Leave the original top-level source files untouched

Documents

• Cards
• Card Pool Audit
• Card Pool Wave 1 Recommendations
• Ability Definitions
• Tutorials
• Recommendations
• Canon JSON

Format Choice

This prototype uses JSON instead of YAML for the structured layer.

Why JSON here:

• Better direct support in most programming toolchains
• Easier validation against future schemas
• Cleaner ingestion for game tooling and AI pipelines
• Less ambiguity around indentation and scalar parsing
