Added GPT-5.2 Mini (fallback model) to available_models across all plans. Added bundled_tools (Codex CLI, DALL-E, Sora, Deep Research) to Plus, Pro, Business, and Enterprise plans.

Full pricing audit: all plan prices (Free $0, Go $6, Plus $20, Pro $200, Business $25/$30, Enterprise custom) verified against chatgpt.com/pricing. No changes needed.

Added ChatGPT Go ($6/month US baseline) to personal plan lineup and normalized plan comparison semantics for Free/Go/Plus/Pro.

Expanded coding-first trust sources with Codex pricing and flexible pricing docs to clarify usage limits, overage behavior, and credits flow.

OpenAI vendor reference was standardized to chatgpt.com/pricing, with plan-level pricing and billing checks validated from official Help Center plan articles.

Codex and flexible pricing behavior were clarified by plan: Plus/Pro support credit top-ups, while Business/Enterprise use shared flexible pricing pools for overage.
