+# Bounty Video Bug-Report Challenge
+
+## Overview
+This challenge enables miners to submit video bug-reports for bounty rewards.
+
+## Workflow
+1. Miner uploads video via multipart form to `/submit` on `:8095`.
+2. Service compresses video using `ffmpeg`.
+3. Service checks for duplicates using OpenRouter DeepSeek V4 Flash.
+4. If duplicate found within 24h, returns `409 Conflict`.
+5. Otherwise, saves as `PENDING` in PostgreSQL.
+6. Admin approves via `/approve/:id` with `X-Admin-Token`.
+7. Approved submissions trigger `score_epoch` TARGET=50 emission with uid0 burn sink.
+
+## Trust Root Weights
+Configured in `config/challenges.toml`:
+- design: 3000 bps
+- prism: 4500 bps
+- bounty: 2500 bps
+
+## Edge Cases
+- Bad multipart: `400 Bad Request`
+- Similarity reject within 24h: `409 Conflict`
+- Unauthorized admin: `401 Unauthorized`
