# Proof Verifier (End-to-End)

This skill verifies a proof chain as far as you provide artifacts:

1) **Merkle Forest**: ROOT.txt + leaf/level files (optional)  
2) **RFC3161**: request.tsq + response.tsr (optional)  
3) **Ethereum**: tx hash + receipt (optional)  
4) **Bitcoin**: txid + node visibility (optional)

It is **read-only**. No funds move, nothing changes on the system.

## Quick Start

```bash
cd ~/.claude/skills/proof-verifier

# point to a merkle-forest run dir
export MERKLE_RUN_DIR="$HOME/.claude/skills/merkle-forest/outputs/runs/<run>"

# optional: rfc3161 outputs
export RFC3161_DIR="$HOME/.claude/skills/rfc3161-anchor"   # where request.tsq/response.tsr live

# optional: eth-anchor outputs
export ETH_RUN_DIR="$HOME/.claude/skills/eth-anchor/outputs/runs/<run>"
export ETH_RPC_URL="https://..."

# optional: btc-anchor outputs
export BTC_RUN_DIR="$HOME/.claude/skills/btc-anchor/outputs/runs/<run>"
export BTC_NETWORK="testnet"

./scripts/00_preflight.sh
./scripts/10_plan.sh
./scripts/11_verify.sh

./scripts/99_report.sh
```
