Atlas Ruling — S55, FLAG-053, and S40-Baseline Diagnostic

Date: 2026-04-22 From: Atlas (CSO) To: Vesper, Katja, Orion

Rulings

1. S40-Baseline Diagnostic — APPROVED

Diagnostic clone approved. Purpose: determine whether fills are achievable under a simpler pre-cascade control model. This is a diagnostic branch, not a recovery branch.

Constraints: - Fresh DB, no reuse of main branch state - Seed current on-chain balances (79.684 XRP / 83.463 RLUSD) - No changes inside the diagnostic clone before first run — historically faithful - 10–15 minute initial window only; extend only if behaving meaningfully - No production inference from one run — comparative evidence only

Measure: fills, quote placement, order survival, realized spread, whether engine self-idles, inventory drift, CLOB conditions.

2. FLAG-053 — FILE NOW

Title: ANCHOR_IDLE / dual-signal convergence and reporting mismatch

Two potentially related issues under one flag: 1. Signal/reporting mismatch — dashboard anchor sign vs tick-level CLOB-AMM divergence sign (opposite signs in S55) 2. EMA deadlock / non-progress — if EMA cannot converge while idle, ANCHOR_IDLE becomes a trap state (architecturally unacceptable)

3. Further sessions on main — NO

Hold main branch until Orion's investigation is complete. Exception: S40-baseline diagnostic clone only.

4. Did we drift from the agreed progression? — YES

Not in bad faith. But real bugs forced reactive patches faster than the system was being re-simplified. Cumulative interaction space widened faster than legibility was maintained. Katja is correct to call it out.

Corrective Posture

  • Freeze main-branch progression temporarily
  • Investigate signal coherence (FLAG-053, Orion)
  • Run S40-baseline diagnostic
  • Re-establish legibility before resuming

Must be able to answer: what the anchor signal means, why ANCHOR_IDLE is entered, what causes exit, whether dashboard and tick logs are consistent, whether the engine can still participate in the current market under a simpler stack.

Approved Execution Order

  1. File FLAG-053
  2. Orion completes investigation report (sign mismatch + EMA progression + ANCHOR_IDLE exit mechanics)
  3. Prepare S40-baseline diagnostic clone
  4. Run short diagnostic session on clone
  5. Compare clone behavior against current branch
  6. Return to architecture ruling

Atlas Bottom Line

"The current control surface is no longer legible enough to justify continued normal iteration. The correct move is: hold, diagnose, compare, simplify if needed."
