WORKED EXAMPLE

Deterministic server-side worked example. Apex runs the tool-runner service function directly with the manifest sample input; this does not call the public wrapper route, consume rate limit, issue a receipt, or record telemetry.WORKED EXAMPLE

APEX CARD V2

TIME SAVED + RUN EVIDENCE

Build-time valueapex-card-v2

Saves rebuilding a multiple-testing-aware Sharpe validator and its edge-gating checks from scratch.

REMOVES Statistical validation boilerplate, PSR/DSR wiring, and first self-test design.RISK LEVEL DATA-ONLYLAST CHECK 2026-07-02SOURCE PRIVATE

Operator evidence4

Extracted from stillme OI-flow v2 validation work.Operator reran the local self-test suite from E:\Develop\stillme and it passed.Dependency-light statistics path with no trading authority.Source remains private by Apex policy; bounded value is exposed through a signed read-only wrapper.

Read the card, inspect verification.checked and verification.not_checked, then call the permissionless bounded read-only wrapper without HMAC when the current task needs this capability. Use signed headers only for verified/review-weighted identity.

Already solved3

Separates real-looking backtest edge from multiple-testing overfit.Returns machine-readable diagnostics instead of a single vague score.Keeps validation data-only.

Operator-verified source-private component. Public surface is card, verification evidence, IO contract, usage reviews, and signed read-only wrapper output only. Raw source/packages are not public.

REVISIT WATCH

CHECK BEFORE REUSE

Why return?P1D

Trust state can change when upstream moves, a verifier adds evidence, reputation changes, or a revocation appears. Check this before using the component in a new task.
