Do not ignore every test path.
A slashless test pattern recursively ignores any file or directory with that name, which can silently exclude test source. Remove it or scope it to the intended generated artifact.

Express.js 4.x 5.x strictRouting trailing slashes /foo and /foo/ route matching
💡 Result:
In Express.js, both version 4.x and 5.x provide a strict routing option that controls how the router handles trailing slashes in request paths [1][2]. By default, the strict routing option is disabled (false) [1][2]. When it is disabled, Express treats paths with and without a trailing slash (e.g., /foo and /foo/) as identical, meaning they will match the same route [1][2]. When the strict routing option is enabled (true), the router treats /foo and /foo/ as distinct, different routes [1][3]. To enable this behavior, you can pass the strict: true option when creating a router instance [1][2]: const router = express.Router({ strict: true }); This setting applies to the specific router instance. If you are using the main application object as a router, note that Express applications do not typically expose a direct configuration option for strict routing at the app level in the same way, though you can use a mounted router to enforce this behavior for specific sub-paths [1][2].

Normalize paths before checking blocked routes.
Exact matching lets trailing-slash variants such as /submit/ bypass the middleware while Express still dispatches them to the /submit handler. Strip a single trailing slash from every non-root path before SUBNET_ROUTES.includes(...) and add coverage for the blocked route variants.

Validate and canonicalize the Nethermind count before storing/updating it.
parseInt(params["...-count"]) can disagree with the raw NUM_NETHERMIND value, and negative values bypass chainspec generation while still being written to the environment. Server-side normalize the count to a non-negative safe integer (or reject invalid values), write that normalized value to NUM_NETHERMIND, and add min='0'/step='1' to the form input.

XDPoS v2 allConfigs masternodeReward protectorReward observerReward chainspec.json
💡 Result:
In the XDC Network's XDPoS v2 consensus mechanism, reward distribution is managed via a V2 configuration structure, often defined within the network's chain specifications [1][2]. These rewards are designed to incentivize different node roles, specifically Masternodes (Core Validators), Protector Nodes, and Observer Nodes [1][3][4]. The configuration parameters for these rewards are typically structured within a V2Config object or a similar configuration map, which can be found in source code files such as params/config_networks.go [1][2]. The relevant structure for these parameters is defined as follows [1]: type V2Config struct { MasternodeReward float64 json:"masternodeReward" ProtectorReward float64 json:"protectorReward" ObserverReward float64 json:"observerReward" MaxProtectorNodes int json:"maxProtectorNodes" MaxObserverNodes int json:"maxObserverNodes" } Key Implementation Details: 1. Reward Mechanism: Unlike V1, which focused on block rewards, XDPoS v2 calculates and distributes rewards per epoch (consisting of 900 rounds/blocks) [1][4]. 2. Configuration Storage: These parameters are part of the broader allConfigs map in the chainspec.json (or hardcoded genesis/params files), which allows the network to apply specific reward settings based on the current epoch or switch block [5][2]. 3. Hierarchy: The rewards are tiered. Core Validators (Masternodes) generally receive the highest rewards, followed by Protector Nodes (which act as hot backups), and then Observer Nodes (which monitor consensus without producing blocks) [3][4]. 4. Example Values: While these values are network-dependent, recent testnet configurations have used parameters such as MasternodeReward: 63.42, ProtectorReward: 50.27, and ObserverReward: 25.13 for specific protocol versions [2]. These are subject to governance and network upgrades [1][4]. For operators setting up nodes, these values are typically handled by the network's consensus engine parameters rather than manual configuration in a user-facing file, though they are visible and verifiable within the genesis block configuration or the node's chain parameters [2][6][4].

Do not silently zero V2 round rewards for Nethermind.
genesis-to-chainspec.js emits chainspec.json for Nethermind nodes, and lines 147-149 overwrite every round’s masternodeReward, protectorReward, and observerReward. If the generated genesis.json is a valid XDPoS v2 genesis, persist those values (or fail generation with a clear unsupported-rewards error) instead of deploying a network where configured economics are changed without an explicit opt-in.
