Pengyi Fund · A500 Enhancement Data Foundation
Data built to earn production trust.
A governed path from investment data requirements to immutable raw evidence, reproducible clean datasets, and explicit production approval.
One system · Three control planes
From demand to trusted data.
PENGYIDATA separates what a strategy needs, how data physically lands, and whether an immutable snapshot is permitted to serve research, paper trading, or production.
Data Requirements
Define A500 benchmark, market, fundamental, event, news, sentiment and alternative-data needs with point-in-time semantics.
Open requirements ↗ Data engineeringRaw & Clean Landing
Preserve source-faithful immutable Raw snapshots, then derive canonical Clean snapshots with deterministic lineage.
Open landing system ↗ Trust controlRisk, Approval & Audit
Gate datasets through quality, point-in-time, licensing, operational and human-review evidence before production use.
Open audit control ↗Current blueprint
A500 data scope.
These figures describe the current contract design—not live production feeds. Status becomes operational only after ingestion and approval evidence exist.
Controlled state transition
The route to production.
Downloaded data is not trusted data. Clean data is not automatically production data. Every transition creates evidence and remains reversible.
