…tem 2 parked) GOAL_CUTOVER_READY.md Phase 2, chunk C1 (inventory: journal s7). The engine now always runs the Clojure semantics on degenerate input: - _compute_pca: only a truly-EMPTY matrix short-circuits (Clojure runs real math on 1x1 — every-vote step-0 oracle); the improved-mode <2 guard is deleted. - _compute_clusters: the <2-in-conv-participants early return and the <2-base-clusters early return (improved-only) are deleted — degenerate ticks fall through to the full base->group chain exactly like conversation.clj (max-k always >= 2). - conv_repness: the <2 matrix guard is deleted — repness/consensus computed at every size (best-agree guarantee). The deleted improved-mode guards are queue item 2 in POST_CUTOVER_IMPROVEMENTS.md; the improvements/* park commit is minted at the end of the collapse (reverse of this commit's guard hunks). Improved-mode guard tests deleted with their branches (test_degenerate_tick_parity.py). Legacy tests unchanged and green. commit-id:13e86ed3
