Use Assume for fixture invariants.
Replace these new assert and Assert calls with Assume. A missing test fixture dependency is an invariant failure. It does not require an immediate crash for memory-safety or persisted-state protection.

Both Assert and assert are accepted project patterns, and the new check matches the existing assert(m_node.cj_walletman) after the same factory call in TestingSetup. The two coinjoin_inouts_tests.cpp sites are outside this PR's diff and already exist in the merge base, so this is neither an in-scope correctness issue nor a necessary change.

@thepastaclaw, agreed on the two src/test/coinjoin_inouts_tests.cpp call sites. They are outside this PR and should not be part of this finding.
The new assert(m_node.cj_walletman) at Line 386 remains in scope. The fixture check is an invariant, and the supplied guideline specifies Assume(cond) as the default for this case. The existing matching assert does not change that guidance.
Please limit this finding to Line 386.

Learning: In dashpay/dash, the CMake configuration strips `-DNDEBUG`/`/DNDEBUG` from release-mode compiler flags (per `src/secp256k1/CMakeLists.txt`), so `assert()` remains enabled in all build types. Therefore, in this repository, do not treat bare `assert()` usage as “unsafe-in-release-builds” or a release-only issue; only flag `assert()` concerns when there is a different, concrete problem (e.g., side effects, incorrect assumptions, or thread-safety), not based solely on release/build-type behavior.

Resolved differently in c43e3e4: the new assert is removed entirely rather than converted. CJWalletManager::make() unconditionally returns std::make_unique, so the pointer can never be null and neither assert nor Assume can ever fire — the check was noise. The constructor's pre-existing assert and the two coinjoin_inouts_tests.cpp sites are outside this PR's diff, as already agreed above.

When a wallet-enabled fixture has already added a wallet through CoinJoinLoaderImpl::AddWallet() and then calls LoadVerifyActivateChainstate(), this reset destroys the only m_wallet_manager_map entries, while the newly constructed manager below is never repopulated from the still-loaded wallets. Subsequent loader operations such as WithClient() therefore return false and CoinJoin processing silently stops for those wallets; preserve or re-register the loaded wallets as part of the rebuild.

Addressed in c43e3e4 by documenting the invariant at the rebuild site rather than re-registering: no current fixture has wallets loaded when the chainstate is reloaded (verified all three caller families), and setup_common cannot reach the shared_ptr that addWallet() requires without new plumbing. Details in the thepastaclaw thread on this line.

Preliminary review — Codex only
The PR correctly rebuilds the managers around chainstate replacement and reconnects CConnman to the new PeerManager, but rebuilding CJWalletManager discards all existing CoinJoin wallet registrations. This leaves wallets that remain loaded across the fixture reload unavailable through CoinJoinLoaderImpl, so the registrations must be restored before the lifecycle fix is complete.

🔴 Blocking: Restore wallet registrations in the rebuilt CoinJoin manager

Verified against every caller of LoadVerifyActivateChainstate(): TestingSetup's constructor (runs before any wallet can load), the utxo_total_supply fuzz target (plain ChainTestingSetup, no wallet loader), and the SnapshotTestSetup tests (none load a wallet). No wallet is ever registered when the rebuild runs, so WithClient() cannot regress anywhere in the current suite.
For a hypothetical future fixture that loads a wallet and then reloads, the pre-PR state was not "working CoinJoin" — the surviving manager held a dangling chainman reference after SimulateNodeRestart() and, on the reindex path, freed mempool/dmnman/isman. Preserving the old manager preserved undefined behavior, not registrations.
Re-registering from setup_common.cpp is not cleanly possible today: addWallet() needs a shared_ptr<CWallet>, which the test util cannot reach (WalletContext is private to WalletLoaderImpl; interfaces::Wallet::wallet() exposes only a raw pointer). Rather than add plumbing plus dead, untestable re-registration code for an unreachable case, c43e3e4 documents the invariant at the rebuild site: a future test that loads wallets before a reload must re-register them with the new manager. Happy to add the plumbing in a follow-up if a test actually needs it.

Resolved in this update — Restore wallet registrations in the rebuilt CoinJoin manager no longer present.
Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
PeerManagerImpl holds the mempool, dmnman, isman, clhandler and llmq_ctx by reference; CJWalletManagerImpl holds the chainman, dmnman, mempool and isman. LoadVerifyActivateChainstate() always recreates llmq_ctx (via LoadChainstate) and, since dash#7603, its reindex path also replaces the mempool and those managers, so a fixture that already built peerman or cj_walletman (any SnapshotTestSetup test reloading after SimulateNodeRestart) was left holding dangling references for the rest of the test. Nothing dereferences them today, but any future use would silently read freed memory. Tear both down before the reload and rebuild them afterwards, mirroring AppInitMain, which constructs them only after the chainstate is loaded. connman's raw m_msgproc pointer is cleared for the duration of the reload and wired back up to the new peerman at the end.

Final validation — Codex/Sol only (Phase 2 disabled)
The lifecycle change tears down and reconstructs both managers in the correct order and reconnects CConnman to the replacement PeerManager. The current reload callers do not have registered wallets, so the previously reported wallet-registration issue is intentionally deferred, but the rebuilt managers and CConnman wiring remain untested and the pre-PR behavior would still pass the existing suite.

Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

- [SUGGESTION] src/test/util/setup_common.cpp:382-398: Exercise the rebuilt managers in a regression test
The snapshot tests call `LoadVerifyActivateChainstate()` but never access `m_node.peerman` or `m_node.cj_walletman` afterward, and they do not verify that CConnman routes message processing through the replacement PeerManager. As a result, removing this rebuild or leaving CConnman's `m_msgproc` connected to the old manager would not necessarily fail the current suite—the pre-PR dangling-reference behavior passed these same reload tests. Add a focused snapshot-restart test that uses the replacement PeerManager through CConnman after reload and exercises a CoinJoin manager operation against the rebuilt dependencies when wallet support is enabled.

Follow-up to #7603: latent dangling references in the test fixtures.
PeerManagerImplholds the mempool, dmnman, isman, clhandler and llmq_ctx by reference;CJWalletManagerImplholds the chainman, dmnman, mempool and isman.ChainTestingSetup::LoadVerifyActivateChainstate()always recreatesllmq_ctx(insideLoadChainstate()), and since #7603 its reindex path also replaces the mempool and those managers. AnySnapshotTestSetuptest that reloads the chainstate afterSimulateNodeRestart()therefore leftm_node.peermanandm_node.cj_walletman(built earlier byTestingSetup) holding dangling references for the rest of the test. Nothing dereferences them today — neither object is registered as a validation interface in unit tests, no scheduled tasks or handlers exist, and their destructors don't touch the referenced objects — but any future test touching them after a reload would silently read freed memory.What was done?
LoadVerifyActivateChainstate()now tears downcj_walletmanandpeermanbefore the reload (when the fixture had built them) and rebuilds them afterwards, mirroringAppInitMain, which constructs them only after the chainstate is loaded.connman's rawm_msgprocpointer is cleared for the duration of the reload and wired back up to the new peerman at the end. Fixtures that never built them (plainChainTestingSetup, theutxo_total_supplyfuzz target,TestingSetup's own constructor-time call) are unaffected.How Has This Been Tested?
