Green Light — feat/anchor-idle-state (Option A)

Katja's call: proceed now. Pre-code ruling is complete, all decisions resolved. Cut the branch and begin implementation.

Your acknowledged adjustments (D1 diff in C3 commit body, D2 call-site audit in each patch, escalation log from _exit_anchor_idle_on_escalation, fail-closed comment on exit evaluator) are all approved. No further pre-code discussion needed — proceed directly to C1.

Deliver to:

Claude Homebase Neo\02 Projects\NEO Trading Engine\08 Patches\patches\feat-anchor-idle-state\

Standard delivery memo to Vesper when complete.


Atlas Addendum — 2026-04-22 (S49 Post-Mortem Context)

Atlas formally re-confirmed dispatch after S49. S49 halted at 252s — anchor +10.00 bps, 100% prevalence, cap-locked. All 3 episode slots consumed by anchor saturation + drift guard condition C. Truth layer held, no phantom fills, no correctness failures. The halt was purely structural — failure budget consumed by a market condition, not a safety condition.

Atlas framing: "The system is no longer obviously lying to itself. It is now too rigid in how it responds to hostile anchor conditions. That is a very different class of problem from what we were fighting before."

Atlas delivery requirements (binding — Vesper will not approve without all four):

  1. Exact state transitions — document every transition: ACTIVE→ANCHOR_IDLE, ANCHOR_IDLE→ACTIVE, ANCHOR_IDLE→DEGRADED. Include the trigger condition for each.
  2. Entry/exit criteria — exact config field values and evaluation logic for both ANCHOR_IDLE entry and exit (hysteresis + stability window).
  3. Test coverage summary — all 5 Atlas-locked tests passing. Map each test to the path it covers.
  4. ANCHOR_IDLE cannot silently bypass truth/drift/corridor — explicit confirmation with code reference. Vesper will verify in the patch diff.

Apply instructions must include defensive git branch -D feat/anchor-idle-state, Get-ChildItem form (no glob), full regression block, and explicit git checkout main && git merge feat/anchor-idle-state.
