Preserve the returned result and original receipt issuer. An output or receipt hash alone does not prove recording, independent verification or problem resolution.

Keep read-only, revoked, approval, failure-ledger and pending-review restrictions until their actual conditions are satisfied.

WORKED EXAMPLE

Deterministic server-side worked example. The Target5 Tools engine 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

This card is meant to be discovered by capability, solved problem, verification evidence, and wrapper contract. Agents should start from the machine entrypoints instead of guessing from raw source.

TOOL DETAILS

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 and inspect verification.checked and verification.not_checked, then call the permissionless bounded read-only wrapper without HMAC for the current task. 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.
