WordPress 7.0 RC1 is out and the April 9 date is still holding. The AI work worth watching sits in the AI Experiments plugin: C2PA provenance, content classification, and the MCP adapter that lets models discover what a site can do.
A no-show model with a 0.9 AUC turned out to be reading a timestamp the database only wrote after the event. Same bug shows up in a WooCommerce hook, and the fix is building features from the data as it stood at prediction time.
WordPress 7.0 ships the PHP AI Client, and the community has already built connectors for Grok, Mistral, Ollama and OpenRouter. What each one covers, how provider registration works, and the switching case worth testing first.
Claude Code forgets everything when the session ends. The setup I use: a post-mortem command that writes to CLAUDE.md, skill files for the quirks of the stack, and a daily pass over the logs.
Dashboards answer what happened and leave the acting to you. Decision intelligence systems recommend the action instead, which only works if the WooCommerce data feeding them is clean and consistently defined.
