# Runbooks — Master Index

**Last Updated:** 2026-05-11  
**Purpose:** Single entry point for all operational runbooks.

**Canonical index:** [03-deployment/OPERATIONAL_RUNBOOKS.md](03-deployment/OPERATIONAL_RUNBOOKS.md) — use that document as the master index of every runbook (Besu, CCIP, Blockscout, maintenance, liquidity, network, etc.). **Doc hygiene:** [MASTER_INDEX.md](MASTER_INDEX.md) status block lists the latest verification snapshots (E2E, submodules, DealFlow).

This file exists for backward compatibility with links that point to `RUNBOOKS_MASTER_INDEX.md`. All content and links are maintained in [03-deployment/OPERATIONAL_RUNBOOKS.md](03-deployment/OPERATIONAL_RUNBOOKS.md).
