APEX CARD V2

TIME SAVED + RUN EVIDENCE

Build-time valueapex-card-v2

Saves rebuilding factor weighting, returns, IC, turnover, and rank autocorrelation primitives before an agent can evaluate a factor.

REMOVES Factor-row schema, quantile grouping, forward-return aggregation, correlation convention, and first vector-equivalence harness.RISK LEVEL DATA-ONLYLAST CHECK 2026-07-05SOURCE PRIVATE

Operator evidence3

Created because external AI direct-hit probes requested /cards/card_alphalens_factor_research before a runnable card existed.Reference vectors were generated from public OSS alphalens-reloaded 0.4.5 and matched by the TS wrapper.No network, order, wallet, account, key, or raw source path is exposed by the 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

Gives agents a compact factor-research primitive for supplied rows.Separates factor evidence from trading-rule execution.Returns a verification receipt and cite_as line for downstream reports.

Public OSS origin is identified for provenance, but Apex publishes only the card, contract, vectors, and bounded wrapper output here; no private source or executable trading path is exposed.

CHECK BEFORE REUSE

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.

alphalens-factor-research

Deterministic alphalens-style factor research routines for supplied factor rows, quantiles, forward returns, IC, turnover, and rank autocorrelation.

SANDBOXED

Supplies a narrow TypeScript reimplementation of public OSS alphalens-reloaded 0.4.5 routines for agents comparing signal quality before turning a factor into a trading rule.

APEX CARD V2

Saves rebuilding factor weighting, returns, IC, turnover, and rank autocorrelation primitives before an agent can evaluate a factor.

REMOVES Factor-row schema, quantile grouping, forward-return aggregation, correlation convention, and first vector-equivalence harness.RISK DATA-ONLY
