Session Summary — S47 (session_id=50)¶
Key Outcome¶
FLAG-037 CONFIRMED CLOSED. CANCELLED_BY_ENGINE guard worked correctly throughout. No phantom fill cycle. This is the primary result of this session.

FLAG-037 Confirmation¶
CANCELLED_BY_ENGINE guard fired correctly for both cancelled orders (offer_sequence 103476194 and 103476195):
RECONCILER_SKIP_ENGINE_CANCELlog token confirmed on every subsequent tick- Truth check: delta_xrp=3.97e-05, delta_rlusd=0.0 →
status: ok - Engine exited DEGRADED cleanly on truth-ok: "Exiting DEGRADED mode — truth check returned ok, resuming quoting"
- No
inventory_truth_halt - No phantom fill cycle
FLAG-037 is CLOSED. The two-layer implementation (C1-C7) is confirmed correct.
Halt Analysis¶
Halt: degraded_episode_limit_halt — FLAG-044 episode cap (3 degraded episodes per source per session).
Episodes in this session:
1. Drift guard — condition C (no opposing fill after 16 ticks post-buy fill at 06:02:08). DEGRADED entered, cancel_all fired, truth check ok, DEGRADED exited.
2. Anchor saturation — mean=−7.11 bps, 64% prevalence over 25 ticks. DEGRADED re-entered (FLAG-044 cooldown for drift armed, 120 ticks).
3. Third episode triggered episode limit → degraded_episode_limit_halt.
This is correct FLAG-044 behavior. No fault.
Anchor Regime¶
| Metric | Value |
|---|---|
| Mean | −5.62 bps |
| Median | −5.17 bps |
| Range | [−10.0, +1.7] |
| Bias | Negative |
| |err|>5bps | 50% |
Regime remains hostile (negative bias, 50% >5bps — at the boundary of the saturation guard threshold). However, CLOB-AMM divergence improved during this session (1-3 bps at times — the most favorable conditions since S42). The anchor bias shift from positive (S43-S45) to negative (S46-S47) is a structural change worth watching.
Momentum Filter¶
- Buy suppressions: 3
- Sell suppressions: 1
Actions Required Before S48¶
-
Realignment dry-run (expected near-zero delta — FLAG-037 fix prevents phantom fills, only real inventory change is the 1 buy fill of 2 RLUSD):
If delta is negligible (< 0.1 XRP / < 0.1 RLUSD), proceed withoutpython tools/realign_inventory_to_onchain.py --config config/config_live_stage1.yaml --db neo_live_stage1.db --dry-run--confirm. -
No code changes required before S48. All active guards are working correctly.
Open Items (not blocking S48)¶
- FLAG-040 (WAC correction) — now unblocked post-FLAG-037. Low urgency, display-only. Queue for next Orion pass.
- FLAG-045 (CANCELLED_BY_ENGINE accumulation in reconcile set) — low urgency. Monitor in longer sessions.
- FLAG-038 (apply_fill zero-qty silent drop) — open, low urgency.
Phase 7.4 Precondition Status¶
S47 does NOT count toward the 2 clean session precondition (halt ≠ duration_elapsed). Session count: 0 / 2 clean sessions.
Anchor regime and CLOB-AMM conditions are the key variable for next session. If CLOB-AMM stays in the 1-3 bps range observed during S47, the engine will have more quoting time before guards fire.
