Phase 7.4 Status¶
NOT counting toward Phase 7.4 clean session precondition (halt ≠ duration_elapsed).
Ending Inventory (post-realignment)¶
- XRP: 79.507004 (on-chain confirmed)
- RLUSD: 83.463491 (on-chain confirmed)
- Total: ~196.77 RLUSD equivalent
Root Cause — inventory_truth_halt¶
FLAG-047: Cancel-fill race condition.
At 07:06:24 (tick ~172), truth check fired with: - on_chain_xrp=79.507004 vs internal=72.189397 → delta_xrp=−7.317607 - on_chain_rlusd=83.463491 vs internal=93.963491 → delta_rlusd=+10.5 RLUSD
This is a real fill (buy ~7.32 XRP / sell ~10.5 RLUSD) that was never recorded internally.
Sequence:
1. Engine enters DEGRADED → cancel_all fires → marks order CANCELLED_BY_ENGINE in DB before gateway submit
2. Counterparty fills the order on-chain before the cancel transaction arrives on the ledger
3. Cancel transaction gets tecNO_ENTRY (offer already gone)
4. Reconciler sees order in CANCELLED_BY_ENGINE state → fires RECONCILER_SKIP_ENGINE_CANCEL → skips fill recording entirely
5. Internal inventory stays at pre-fill values
6. Truth check sees the on-chain delta → inventory_truth_halt
This is distinct from the phantom fill cycle (FLAG-037). FLAG-037 was suppressing phantom fills from successfully-cancelled orders. FLAG-047 is suppressing real fills where the cancel arrived after the fill.
Realignment¶
Dry-run confirmed:
XRP: ON-CHAIN 79.507004 / INTERNAL 72.189397 / DELTA +7.317607
RLUSD: ON-CHAIN 83.463491 / INTERNAL 93.963491 / DELTA -10.500000
--confirm run by Katja. DB updated. Internal state now matches on-chain.
Anchor Regime Note¶
S48 anchor mean +2.94 bps is the best regime seen since hostile conditions began. CLOB-AMM divergence appears to be compressing. If this trend holds, conditions may be approaching the favorable range for Phase 7.4 clean sessions — once FLAG-047 is resolved.
Flags Filed This Session¶
- FLAG-047 — OPEN SESSION-BLOCKING: Cancel-fill race condition. S49 blocked until resolved.
Actions Required Before S49¶
- Orion: fix FLAG-047 — implement Option A (CANCEL_RACE_UNKNOWN state when cancel returns "not found," trigger on-chain tx history check) or equivalent
- Realignment dry-run before S49 launch (expected near-zero delta post-realignment)
- No further pre-session blockers (FLAG-037 confirmed fixed; FLAG-046 ANCHOR_IDLE patch applies tomorrow)
Orion Work Status¶
- FLAG-046 (ANCHOR_IDLE): Implementation in progress. 4-commit sequence approved. Patch bundle delivery expected. Apply tomorrow.
- FLAG-047 (cancel-fill race): New task. Should be sequenced as separate branch. Flag is SESSION-BLOCKING — prioritize over FLAG-046.
