Igra Sentinel Stack

Chain safety gates and dual-network probes for Igra EVM — Galleon testnet rehearsal (chain 38836) plus read-only Igra mainnet health (chain 38833).

This is a slim, standalone companion to kaspa-frontier-engine. Swap routing, hub deploys, and the full DEX terminal remain in the frontier repo.

What this is

Layer	Shipped here
Network probes	Galleon + Igra mainnet RPC reachability, read-only detection
Safety gates	SHA-256 commitment checks (POST /v1/evm/safety-verify) — not on-chain ZK
Bridge verify	KatBridge KIP-21 structural checks (POST /v1/funding/bridge-verify)
Wallet connect UI	EIP-6963 + WalletConnect on Galleon (/ui/dex)
Client hooks	Fail-closed CLI before broadcast (python -m sentinel_stack.hooks)

What this is not

• Not an Igra Labs partnership, grant, or endorsement (not_partnership: true on all catalog endpoints).
• Not mainnet production sentinel — no FeePool/hub deploy on chain 38833 in this repo.
• Not consensus or SilverScript ZK — commitments are off-chain SHA-256 only.
• Not StrataX / Guard Sentinel — that is a separate product.

Quick start
