refactor: Move decreaseOwnerCount onto AccountRootEntry

Replace the entry-taking decreaseOwnerCount free function with a writable member of AccountRootEntry, and drop the temporary friend declaration from the previous change. The member uses the entry's view and journal, so call sites pass their journal to the entry constructor. The AccountID-based overload stays as a shim.

Mayukha Vadari	16389dcb2e	refactor: Move decreaseOwnerCount onto AccountRootEntry Replace the entry-taking decreaseOwnerCount free function with a writable member of AccountRootEntry, and drop the temporary friend declaration from the previous change. The member uses the entry's view and journal, so call sites pass their journal to the entry constructor. The AccountID-based overload stays as a shim.	2026-10-05 15:46:48 +01:00
Mayukha Vadari	97a780b29f	refactor: Move increaseOwnerCount onto AccountRootEntry Replace both entry-taking increaseOwnerCount free functions with writable members of AccountRootEntry. The members use the entry's view and journal, so call sites pass their journal to the entry constructor. The AccountID-based overload stays as a shim. adjustOwnerCountSigned becomes a private member. decreaseOwnerCount is a temporary friend so it can still call it until it moves too. adjustOwnerCountImpl moves to namespace detail, because adjustLoanBrokerOwnerCount also uses it.	2026-10-05 15:46:44 +01:00
Mayukha Vadari	654edc9a08	refactor: Move checkReserve onto AccountRootEntry Replace both entry-taking checkReserve free functions with const members of AccountRootEntry. The members keep the ApplyViewContext parameter, because the check needs the transaction, and drop the journal parameter: call sites pass their journal to the entry constructor instead.	2026-10-05 15:46:39 +01:00

Mayukha Vadari	93498952b1	refactor: Move ownerCount onto AccountRootEntry Replace the entry-taking ownerCount(sle, j, adj) free function with the const member AccountRootEntry::ownerCount(adj). The member uses the entry's journal, so call sites pass their journal to the entry constructor. confineOwnerCount moves from the anonymous namespace to namespace detail, because both the member and the owner-count helpers use it.	2026-10-05 15:45:43 +01:00

Mayukha Vadari	e7a8e0336a	test: Drop extern template declarations from SLEBase test An explicit instantiation declaration stops clang from emitting the inline constructors of the header-only entries at -O0, so the debug builds fail to link xrpl_tests (undefined AccountRootEntry constructors). Naming each class in a static_assert already instantiates its definition, which is all the exhaustiveness check needs. (cherry picked from commit `611415e1f9`)	2026-10-05 15:45:38 +01:00
Mayukha Vadari	1d7e40777a	refactor: Move accountReserve onto AccountRootEntry Replace the entry-taking accountReserve(view, sle, j, adj) free function with the const member AccountRootEntry::reserve(adj). The member uses the entry's own view and journal, so call sites now pass their journal to the entry constructor. The AccountID-based accountReserve overload stays as a one-line shim. Adjustment moves to AccountRootEntry.h, since the member takes it. accountCountImpl moves from the anonymous namespace to namespace detail, because both reserve() and xrpLiquid() use it.	2026-10-05 15:45:38 +01:00
Mayukha Vadari	7bb43a243b	test: Declare, not define, entry instantiations in SLEBase test The exhaustive per-entry-type check in the SLEBase gtest used explicit instantiation definitions. Once an entry class gets out-of-line member bodies in its own .cpp (with the explicit instantiation definition there), the test would instantiate the class a second time, and MSVC rejects it with C4661 because those member bodies are not visible in the test translation unit. Explicit instantiation declarations still instantiate the class definition, which is all the check needs. (cherry picked from commit `8b07abc3cd`)	2026-10-05 15:45:37 +01:00

Mayukha Vadari	c35ac1339b	fix: Do not adopt the escrow SLE into an AccountRootEntry Before fixCleanup3_2_0, EscrowCancel passes the escrow SLE to escrowUnlockApplyHelper as sleDest. Wrapping it in AccountRootEntryR fires the "adopted SLE matches bound entry type" assertion in Debug builds (xrpl.app.EscrowToken "IOU Cancel DoApply"). When sleDest is not an AccountRoot, return what the old code returned for it: the tx reserve sponsor's error if the escrow owner submitted the tx, else tefINTERNAL from checkReserve's type check.

Mayukha Vadari	3044073401	refactor: Use AccountRootEntry everywhere Replace raw AccountRoot SLE pointers with the AccountRootEntryR and AccountRootEntryW wrappers in src/libxrpl and src/xrpld/app. - view.read(keylet::account(...)) becomes AccountRootEntryR and view.peek(keylet::account(...)) becomes AccountRootEntryW. - AccountRoot helpers (accountReserve, checkReserve, ownerCount, increase/decreaseOwnerCount, isPseudoAccount, checkDestinationAndTag) and the sponsor helpers (getTxReserveSponsor, getEffectiveTxReserveSponsor, getLedgerEntryReserveSponsor) take or return the wrappers. A missing sponsor is std::nullopt instead of a null pointer. - Generic functions that are not migrated yet (trustCreate, dirLink, addSponsorToLedgerEntry, ...) get rawSle() or mutableRawSle(). - Invariant checks cannot build a view-bound entry, so they use isPseudoAccountSle(), now declared in InvariantCheck.h. This changes pointers only. No helper moves onto the wrapper. It is a pure refactor with no behavior change and no amendment.	2026-10-05 13:33:30 +01:00
