### Overview This PR integrates the `pallet-safe-mode` and `pallet-tx-pause` from Polkadot SDK to provide comprehensive emergency governance controls across all DataHaven runtime networks (mainnet, stagenet, testnet). ### Key Changes #### 🔧 **Core Integration** - **Dependencies**: Added `pallet-safe-mode` and `pallet-tx-pause` from `polkadot-stable2412-6` - **Runtime Integration**: Integrated both pallets across all three runtime networks with pallet indices 103 and 104 - **Call Filtering**: Implemented unified `RuntimeCallFilter` that combines Normal, SafeMode, and TxPause restrictions #### 🛡️ **SafeMode Pallet Configuration** - **Duration**: 1 day activation period (`DAYS` constant) - **Deposits**: Disabled permissionless entry/extension (all `None`) - **Origins**: Root-only for all force operations (`force_enter`, `force_exit`, `force_extend`, etc.) - **Whitelisting**: SafeMode and Sudo calls are immune to restrictions #### ⏸️ **TxPause Pallet Configuration** - **Origins**: Root-only pause/unpause control - **Whitelisting**: SafeMode and Sudo calls cannot be paused - **Max Call Name Length**: 256 characters #### 🏗️ **Architecture** - **Shared Types**: Created `operator/runtime/common/src/safe_mode.rs` with reusable configurations - **Combined Filtering**: `RuntimeCallFilter` applies all three filter layers (Normal + SafeMode + TxPause) - **Consistent Config**: Identical configuration across mainnet, stagenet, and testnet #### 📊 **Infrastructure Updates** - **Benchmarking**: Added both pallets to benchmark suites across all networks - **Weight Mappings**: Placeholder weights using Substrate defaults (ready for chain-specific benchmarking) - **Metadata**: Updated runtime metadata for new pallet exposure #### 🧪 **Testing Framework** - **Coverage**: Tests for individual pallet behavior, combined restrictions, whitelisting, and edge cases ### Emergency Control Capabilities **SafeMode Pallet** (8 calls): - User calls: `enter`, `extend`, `release_deposit` - Force calls: `force_enter`, `force_exit`, `force_extend`, `force_slash_deposit`, `force_release_deposit` **TxPause Pallet** (2 calls): - `pause_call` / `unpause_call` - Granular transaction type pausing --------- Co-authored-by: Steve Degosserie <723552+stiiifff@users.noreply.github.com> |
