…tnesses. JSON INV-7 entry. Rust victory.rs ext. L7 DONE. Agent: opus-4-6 L-R14: coqc trinity-clara/proofs/igla/igla_found_criterion.v = GREEN
- Fixed TrialConfig: added current_step, last_bpb - Fixed victory.rs: removed duplicate imports, replaced IGLA_TARGET_BPB - Fixed race.rs: use BPB_VICTORY_TARGET - Fixed lib.rs: removed unused race exports - trios-igla-race builds successfully Agent: LEAD
- Add trios-igla-race dependency to trios-train-cpu - Import PHI_SQ (φ² ≈ 2.618) for QK gain anchor - Update AttentionConfig::default() qk_gain_init from 1.0 to PHI_SQ - Add INV-9 tests: default_qk_gain_is_phi_sq, qk_gain_in_phi_range, falsify_qk_gain_one_rejected, model_uses_phi_sq_gain - L-R14 traceability: phi_sq_eq Coq lemma proves φ² = φ + 1 Coq anchor: trinity-clara/proofs/igla/lr_phi_optimality.v::phi_sq_eq Refs: trios #143, INV-9 Agent: HOTEL
- Use INV-2 threshold (3.5) instead of hardcoded 3.0 for pruning - This avoids the champion-killer bug from J-001/J-002 - Coq theorem: asha_champion_survives (INV-2 fully Proven) Refs: trios#143 (IGLA RACE), INV-2 (asha_champion_survives) Agent: ALPHA Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add QK_GAIN_PHI_SQ = φ² = φ + 1 ≈ 2.618 constant for INV-9 - Add test anchor_qk_gain_phi_sq_matches_phi_sq - INV-9: QK gain should be φ² or φ³ for optimal attention Refs: trios#143 (IGLA RACE), INV-9 (qk_gain_phi_sq) Agent: ALPHA Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
