TGK Reputation Timeline -- Future Dev Spec

Created: 13 March 2026
Priority: Next sprint (week of 18 March 2026)
Status: Scoped, ready to build
Lives in: /dashboard/keys/ -- middle section

Overview

A graph visualisation on the Keys page showing a member's reputation journey over time. Not just a current score snapshot -- a visual history of how their engagement and contribution has grown since joining TGK.

What It Shows

• Time on the x axis (from member join date to today)
• Keys earned on the y axis
• Activity spikes visible at a glance
• Most recent activity surfaces first
• Filterable by key type (Agree, Insight, Steel Man) using the existing Keys page filter already built and live

Keys Page Layout (full picture)

The Keys page at /dashboard/keys/ will have three sections:

Top -- Keys Overview Total keys earned, broken down by type: Agree (1 key), Insight (2 keys), Steel Man (3 keys). Filter by engagement type already built and live as of 13 March 2026.

Middle -- Reputation Timeline (this spec) Graph visualisation of keys earned over time. Member sees their full journey on the platform at a glance.

Bottom -- Top Contributions Comprehensive list of the member's top contributions sorted by engagement score (keys plus replies), filterable by pillar.

Technical Notes

• Data already exists in Firestore -- this is a visualisation layer only, no new data collection required
• Use D3.js for rendering -- consistent with the Reading Web graph already built and live
• Must be mobile responsive
• Must match TGK visual language -- dark background, gold, card layout
• Sits within the existing Keys page structure, does not require a new page

SaaS Extraction Note

The reputation timeline component is independently extractable. Any community platform that wants to show members their engagement history rather than just a static score has a use for this. Pairs naturally with the Steel Man Engine as part of a community reputation SaaS package.
