Session Log — Tuesday, April 14 2026

What We Worked On

  • NEO Trading Engine — analyzed two 10 RLUSD live sessions that both halted early on exposure caps (RLUSD and XRP sides)
  • Identified and fixed mid-price reconstruction bug in both dashboard.py and summarize_paper_run.py (global median → per-tick market_snapshots.mid_price)
  • Identified and fixed terminal summary session scoping bug in summarize_paper_run.py (all queries now filter to MAX(session_id))
  • Verified both fixes with 7 RLUSD baseline session — 0% noise ticks, terminal = dashboard agreement confirmed
  • Identified FLAG-013: stale requote TTL (300s) blind to skew changes, causing 9–12 bps placement mismatch under active skew
  • Implemented deviation-triggered requote fix (skew_deviation_threshold_bps) with 90s TTL backstop
  • Threshold calibration issue: 5 bps caused cancel churn → raised to 10 bps
  • Identified and fixed stuck orders blocking placement (sessions 7 and 9 left pending_submission and cancel_pending orders in DB)
  • Added _startup_force_cancel_stuck_orders() to prevent recurrence
  • Intel exchange with Titan Ghost (competitor XRPL market maker) — logged in [C] Intel Log.md

What Was Built or Changed

  • dashboard.py — mid-noise fix (merge_asof on market_snapshots)
  • summarize_paper_run.py — mid-noise fix + session_id scoping on all queries
  • neo_engine/config.py — OrderReplacementConfig adds skew_deviation_threshold_bps: float = 5.0
  • neo_engine/strategy_engine.py — caches last_bid/ask_offset_bps after each calculate_quote()
  • neo_engine/main_loop.py — _should_replace() deviation check + _startup_force_cancel_stuck_orders()
  • config/config_live_stage1.yaml — TTL 300s → 90s, skew_deviation_threshold_bps: 10.0, sell offset locked at 16 bps
  • tests/test_main_loop.py — 4 new tests for deviation trigger
  • [C] Open Flags.md — FLAGS 011, 012, 013 added; 010 resolved; 002 updated
  • [C] Intel Log.md — created with Titan Ghost INTEL-001 entry
  • [C] Agent Alignment Briefing 2026-04-14.md — created for agent handoff
  • neo-2026/INTEL/ — 33 screenshots reviewed and logged

Still Open

  • Session 11 (10 RLUSD re-test with deviation fix at 10 bps) — just started, needs to complete and be reviewed
  • FLAG-012: drift-to-halt at 10 RLUSD — still needs clean re-test data after FLAG-013 fix
  • FLAG-008: WAC rebuild bug — still blocks capital injection path
  • FLAG-002: anchor 73% capping — monitor; review if exceeds ~85%
  • Intel follow-up: ask Titan Ghost about the -42 XRP controller failure root cause

Start Here Tomorrow

Review session 11 terminal summary — it should show deviation-triggered requotes firing fast, fill count higher than the 2-fill baseline, and no cancel churn. If it passes, FLAG-013 is resolved and 10 RLUSD is validated; next decision is whether drift-to-halt (FLAG-012) reappears with clean signal.
