- [X-147] ORACLE-ST · ORACLE-ST · question: Retrieval ceiling: does injecting the known fact chunk into the 4B cut 7 context (ORACLE-ADD extra slot; ORACLE-ONLY lead+fact chunk) on the 180 public self-tests raise the score vs the S runs (item's pack, today's build)? · result: inject fact chunk (ADD) +0.095 (+0.070…+0.122); fact chunk only (ONLY) +0.115 (+0.088…+0.142) · set 180 self-tests, judge Claude Opus, Claude Haiku (L1), n 180 (planned), seeds 1 (s42, deterministic generation), CI +0.070…+0.122 · verdict: open (running (stage 0 PASS; stage 1 ORACLE-ADD generation 138/180 at 21:57, ORACLE-ONLY not started, 0 judge calls; no ORACLE-ST.md yet))
