Multi-Harness Shared Brain — GitHub as Source of Truth

Point any coding harness at this file + a brain/ folder and get cross-harness continuity. Works with Opencode, Claude Code, Cursor, Codex, Grok, Cline, Windsurf, or any agent with file read/write + git.

1. Philosophy

GitHub is the durable truth. Each harness is a stateless worker. A cheap classifier is the gatekeeper.

 * Use case: Want to order by meta key = value, while including all posts, not just those matching said meta value.
 * 
 * WP_Query's capacity for ordering has improved so much - but as of right now, it's not possible
 * to get _all_ posts, not just ones where a value may or may not exist, and may or may not equal something, and 
 * have all of those be at the top of results.
 * 
 * My very specific use case: a use can set their city and it's saved as a cookie.
