# Unified Signal Timeline

> View all account activity in a single, stacked timeline.

The core philosophy of SignalArk is **Detect → Stack → Route**. The "Stack" phase is visualized in the **Unified Signal Timeline**, providing sales reps with a complete narrative of an account's intent journey.

## The Stacking Effect

Evaluating a single signal in isolation often leads to low conversion rates. SignalArk aggregates data from multiple distinct tables into a single chronological view:

* **Core Signals** (`signals` table)
* **Market Intelligence** (`market_radar_signals` table)
* **Social Engagements** (`social_engagement_events` table)

When multiple signals occur within a short window, the timeline visually highlights the **Compounding Score**.

  Ten signals from a single job board are less valuable than three signals across a job board, a news article, and a GitHub star. The timeline calculates and displays a **Source Diversity** metric to highlight true organizational momentum.

## Component: CompanySignalTimeline

When reviewing an account, navigate to the **Signal Timeline** tab. Here you will see:

* A chronological feed of all intent events.
* Source-tagged badges (e.g., `funding`, `github`, `news`).
* Inline summaries of why the signal matters.
* A visualization of the account's total intent score over time.

This timeline serves as the foundational evidence base when reps generate AI-powered "Why Now" Briefs or personalize their outreach sequences.
