# Glossary

> Definitions for key terms used across Centaur.

## Aggregate Window

A fixed UTC interval summarized as one Generated Aggregate Narrative Summary.

## Asset Focus

The assets most represented in a trader's selected position sample.

## Direction Bias

The long/short/neutral balance of positions in the selected context.

## Eligible Signed-up User

A Centaur user whose account is active and email-verified. This is the current eligibility rule for Centaur MCP OAuth and self-serve API key management.

## Generated Aggregate Narrative Summary

A generated cross-source market narrative summary for one Aggregate Window. It exposes coverage counts, not source trader or channel identities.

## Generated Channel Narrative Summary

A generated narrative summary for one trader/channel Source Window. Public reads expose `traderId` for continuity but not channel identity or raw source material.

## Ingestion Watermark

The change-feed position used by the partner feed's `since` polling mode. It tracks newly visible event-log rows, not message post time, so a newly ingested retrospective event can make an older source-message group reappear. Persist the newest non-null `nextCursor` from every successful poll, including empty polls, so the watermark advances through quiet periods.

## Low-Signal Summary

A generated narrative summary whose source window has little or no useful trading insight. It is a successful generated output, not a failure.

## Open Position

A position with no captured close in the current public read model. Open-position reads expose current mark-to-market state when pricing is available.

## Open-position Skew

The directional balance of currently open long and short positions for a trader or asset context.

## Partner Feed

The curated read surface at `GET /api/v1/feed` and `list_feed`, gated by `feed.read`. It returns presentation-ready source-message groups with server-curated events, `cursor` scroll-back pagination, and `since` change polling with whole-group upsert semantics.

## Position

A grouped trade record made from related open, increase, decrease, and close events.

## Position History Read

A read of open and closed positions selected by position open time. It includes `1D`, `7D`, and `30D` time-based performance where available.

## Source Message ID

The stable opaque public handle for a source message. Event rows can reference it with `messageId`; message reads can hydrate it with `ids`. Platform source IDs and platform message IDs are source metadata, not public message identity.

## Source Identity

The source account or channel that produced source material. Public message reads expose it under `source.identity` with platform, handle, display name, profile URL, avatar URL, and audience count when available.

## Source Preview

The display-ready source-message payload under `source.preview`. It includes message time, source URL, sanitized text, attachments, and platform-specific flags when available.

## Source Window

A fixed message-time interval summarized as one Generated Channel Narrative Summary.

## Time-Based Performance

Performance measured at a fixed window after position entry, such as `1D`, `7D`, or `30D`.

## Trade Event

A structured action in a position lifecycle: open, increase, decrease, or close.

## Trade Sample Window

The sample of position opens included in a product or stats query, such as `30d`, all-time, custom bounds, or API `startTime`/`endTime`.
