- Add Exploration and Formation axis definitions with feature extraction from source code pattern matching (exploration/formation indicators) - Extend Grid key from (x,y) to (x,y,z,w) with 3⁴=81-cell behavior grid - Update bin assignment, promotion gate, and persistence (JSON snapshot) - Add Slice() for 2-D dashboard visualization across any axis pair - Migration: old 2-D archives project at z=middle, w=middle - Update cross-pollination to pad 2-element behavior vectors to 4 - Add Prometheus metrics to matchmaker (bot crashes, stale job count) - Add rivalry detection to index builder (data/meta/rivalries.json) - Web: batched bot list loading, leaderboard keyboard accessibility, improved ARIA attributes on match/playlist cards Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
