  ## Additional Information

  * Dependent on #6517

  * Dependent on #6594

  * [bitcoin#19101](bitcoin#19101) has been split into two due to it performing two refactors in one commit, the first half deals with utilizing interfaces and managers as defined in `WalletContext` (as opposed to either passing them in separately as arguments or accessing them through globals) and the second half deals with deglobalizing wallet variables like `::vpwallets` and `cs_wallets`.

    * `WalletContext` still needs to be initialized with a constructor as it stores a const-ref `std::unique_ptr` of `interfaces::CoinJoin::Loader`. This requirement hasn't been done away with. Tests that don't have access to `coinjoin_loader` will still need to pass `nullptr`.

    * Bitcoin registers wallet RPCs through `WalletClient::registerRpcs()` ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/wallet/interfaces.cpp#L512-L522)), which a part of the `ChainClient` interface ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/interfaces/chain.h#L292-L293)). They are enumerated ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/wallet/rpcwallet.cpp#L4702-L4776)) differently from non-wallet RPCs ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/rpc/blockchain.cpp#L2638-L2682)).

      Wallet RPCs aren't supposed to have knowledge of `NodeContext` and likewise non-wallet RPCs aren't supposed to have knowledge of `WalletContext`. So far, Bitcoin has reworked their RPCs to maintain this separation and upstream RPCs are a part of the `libbitcoin_wallet` library.

        This isn't the case for some Dash RPCs, many of which reside in `libbitcoin_server`, some of which fit into two categories.

      * Requires knowledge of both `NodeContext` and `WalletContext`
        * Knowledge of `WalletContext` wasn't mandatory before deglobalization as wallet information could be accessed through the global context courtesy of `::vpwallets` and friends but now that it is, many RPCs need to be able to access `WalletContext` when otherwise they wouldn't need to.
        * Due to the mutual exclusivity mentioned above, RPCs that access `WalletContext` _cannot_ access `NodeContext` as their RPC registration logic doesn't give them access to `NodeContext` ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/wallet/interfaces.cpp#L516-L517), `m_context` here is `WalletContext`) but in order to give those RPCs `WalletContext`, we need to register them as wallet RPCs, which prevent us from accessing `NodeContext`.
        * This has been **tentatively** worked around by including a pointer to `NodeContext` in `WalletContext` ([source](https://github.com/dashpay/dash/blob/eea8e42e631575de2968b9c1205c453bad88b135/src/wallet/context.h#L47-L52)) and modifying `EnsureAnyNodeContext()` to fetch from `WalletContext` if regular behavior doesn't yield a `NodeContext` ([source](https://github.com/dashpay/dash/blob/eea8e42e631575de2968b9c1205c453bad88b135/src/rpc/server_util.cpp#L28-L37)).

      * Are RPCs that possess both wallet and non-wallet functionality (i.e. have "reduced" capabilities if wallet support isn't compiled in as opposed to being absent altogether).
        * To enable wallet functionality, the RPCs need to be _registered_ as wallet RPCs. If wallet functionality is disabled, those RPCs are not registered. Simple enough, unless you have an RPC that can _partially_ work if wallet functionality as disabled, as the lack of registration would mean those RPCs are _entirely_ inaccessible.
        * This is also **tentatively** worked around by registering them as non-wallet RPCs in the cases where wallet RPCs aren't registered (i.e. if wallet support isn't compiled in **or** if wallet support is disabled at runtime).
          * Bitcoin doesn't use `#ifndef ENABLE_WALLET` for checking if support is absent, we're expected to use `!g_wallet_init_interface.HasWalletSupport()` (which will always evaluate `false` if support isn't compiled in, [source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/dummywallet.cpp#L19), as the stub wallet would be utilized to initialize the global in those cases, [source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/dummywallet.cpp#L57)). This has been done in the PR.
          * A notable change in this PR is that a lot of behavior that would be enabled if support was compiled in but disabled at runtime would now be disabled if support was disabled at runtime as `wallet_loader` won't be initialized if runtime disablement occurs ([source](https://github.com/bitcoin/bitcoin/blob/62a09a30772141ef4add2f10d29927211abf57eb/src/wallet/init.cpp#L128-L131)), which in turns means that anything that relies on `wallet_loader` wouldn't work either, such as `coinjoin_loader`.

             This means that we also need to register the RPC as a non-wallet RPC if support is compiled in but disabled at runtime ([source](https://github.com/dashpay/dash/blob/eea8e42e631575de2968b9c1205c453bad88b135/src/rpc/evo.cpp#L1841-L1843)).

    * To register RPCs as wallet RPCs, generally they're done through `WalletClient::registerRpcs()`, which iterates through `GetWalletRPCCommands()`. This is perfectly fine as both reside in `libbitcoin_wallet`. Unfortunately, our Dash RPCs reside in `libbitcoin_server` and `registerRpcs()` cannot be extended to enumerate through RPCs not included in its library.

      We cannot simply move the Dash RPCs either (at least in its current state) as they rely on non-wallet logic, so moving the source files for those RPCs into `libbitcoin_wallet` would pull more or less, all of `libbitcoin_server` along with it.
      * To **tentatively** get around this, a new method has been defined, `WalletLoader::registerOtherRpcs()`, which will accept any set of RPCs for registration ([source](https://github.com/dashpay/dash/blob/eea8e42e631575de2968b9c1205c453bad88b135/src/wallet/interfaces.cpp#L603-L606)) and we use it in RPC init logic ([source](https://github.com/dashpay/dash/blob/eea8e42e631575de2968b9c1205c453bad88b135/src/init.cpp#L1513-L1528)).

    * Some usage of `CoreContext` had to be removed ([source](b27d2dc#diff-157f588a09ff1da05b8c74acfcfb4da21917b6a97ed5d2e702228d621d23e66dL1024)) as without those removals, the test suite would crash.

  * [bitcoin#23288](bitcoin#23288) finished what e3687f7 ([dash#6078](#6078)) started and `coinselection_tests` has now been realigned with upstream.
    * Dash-specific tests in `wallet_tests` (as introduced in [dash#3367](#3667)) have not been moved over to descriptor wallets and are still based on legacy wallets (to this effect, the old `AddKey` logic has been retained as `AddLegacyKey`, [source](https://github.com/dashpay/dash/blob/d4e8d1f1628933d9d9159fc261b22fc4427a1c7a/src/wallet/test/wallet_tests.cpp#L873-L879)).

      * To prevent merge conflicts, Dash-specific tests have been moved to the end of the source file and demarcated by a comment ([source](https://github.com/dashpay/dash/blob/d4e8d1f1628933d9d9159fc261b22fc4427a1c7a/src/wallet/test/wallet_tests.cpp#L868)).

  ## How Has This Been Tested?

  6813863 was tested on Debian 12 (`bookworm`) mixing ~1 tDASH on default settings.

  ![CoinJoin run](https://github.com/user-attachments/assets/bdc6a20b-a2f5-4826-96b2-a1954e579e00)

  ## Breaking Changes

  * The RPCs `coinjoin`, `coinjoinsalt`, `getpoolinfo`, `gobject list-prepared`, `gobject prepare`, `gobject vote-alias`, `gobject vote-many`, `masternode outputs`, `protx update*`, `protx register*` and `protx revoke` will no longer be available if wallet support is disabled at runtime. This is not a change in **functionality** as they were already inoperative with disabled wallets but is a change in **reporting** as they would not be available at all.
