+# Sponsorship Automation
+
+This document describes the standard automation flow for GregFramework sponsorship tiers.
+
+## Goal
+
+Keep sponsor tier data synchronized and use it as a source of truth for:
+
+- Discord role sync
+- private/VIP channel access
+- website and wiki placements
+- Mod Store footer sponsor block
+- in-repo sponsor pages and credits
+
+## Repository Workflow
+
+Each repository contains `.github/workflows/sponsor-tier-sync.yml`.
+
+The workflow:
+
+1. runs hourly (and on manual trigger),
+2. queries active GitHub Sponsors,
+3. exports normalized data to `sponsors/sponsors.json`,
+4. commits changes automatically when sponsor data changes.
+
+## Required Secret
+
+Add this repository secret:
+
+- `SPONSORS_READ_TOKEN`: GitHub PAT with access to read sponsor relationships.
+
+Without this secret, the workflow still completes but exports an empty snapshot.
+
+## Tier Mapping
+
+Use this mapping in downstream systems:
+
+- `$1` -> `coffee_supporter`
+- `$5` -> `bronze_backer`
+- `$15` -> `silver_tester`
+- `$25` -> `gold_developer`
+- `$50+` -> `ecosystem_architect`
+
+## VIP Operational Rules
+
+For `$50+` sponsors:
+
+- assign top sponsor placement (Wiki front page + Mod Store footer)
+- create/maintain private 1-on-1 Discord lounge
+- offer featured mod spotlight
+
+## Example Consumer Script (Discord/Wiki Sync)
+
+Use `sponsors/sponsors.json` as input and run a separate scheduled job (bot or CI worker) that:
+
+1. maps each sponsor to a tier role,
+2. grants/revokes Discord roles,
+3. maintains VIP private channels,
+4. updates website/wiki data endpoints.
+
+## First Verified VIP

+Current VIP sponsor:
