Parallel TxFrame creation: Creates TxFrames from XDR envelopes in parallel during transaction set deserialization. Uses work-stealing via std::async with even distribution across available threads. 2. Parallel transaction validation: Validates transactions in parallel in txsAreValid() when there are 2+ transactions. 3. Hash precomputation: Precomputes content and full hashes before parallel operations to avoid race conditions. 4. Test coverage: Adds StreamingShaTest for InvokeHostFunctionSuccessPreImage verification.

This avoids repeated xdr_size() calls during state updates, reducing CPU overhead in the hot path. Also adds Tracy zone to updateState() for profiling visibility.

OpenSSL automatically uses SHA-NI, providing 4.6x speedup for streaming add() (893ns->193ns/call) and 56% total SHA256 self-time reduction (3,744ms->1,659ms per 30s trace). Use opaque aligned storage for SHA256_CTX in the header to avoid naming conflict between OpenSSL's ::SHA256 function and stellar::SHA256 class.

The + commit path is now ~84ms faster than the original sequential ~220ms. + +5. **No TPS change**: The binary search step is 64 TPS. The 28ms saving on a + ~1000ms ledger close may not be enough to cross the next threshold, or the + bottleneck has shifted elsewhere (e.g., `applySorobanStageClustersInParallel` + at 752ms/call dominates the ledger close). + +## Thread Safety +- `mergedEntries`: Both threads read (const ref).

Budget cache accumulates charges across TXs for protocols < p25 The thread-local Budget cache in soroban_proto_any.rs reuses a Budget object across transactions via clone(), which only copies the Rc pointer to the shared BudgetImpl. For p25, reset_budget_for_new_tx() properly resets the counters. For p21-p24 and p26, it was a no-op, so charges from previous TXs accumulated, eventually causing Budget ExceededLimit errors. This broke modifySorobanNetworkConfig (used by many tests) because the 3rd TX in the upgrade sequence would fail. Fix: return bool from reset_budget_for_new_tx (true = reset succeeded). When it returns false, skip the cache and create a fresh Budget. 2. Pre-loaded RO TTL entries silently dropped during parallel apply The Soroban RO entry pre-loading optimization populates the global entry map with mIsDirty=false. When maybeMergeRoTTLBumps merges a thread's TTL bump into a pre-loaded entry, it updates the TTL value in-place but never sets mIsDirty=true, so commitChangesToLedgerTxn skips the entry entirely. Additionally, lastModifiedLedgerSeq was not propagated during the merge, causing stale metadata in subsequent stages. Fix: set mIsDirty=true after successful merge in commitChangeFromThread; propagate lastModifiedLedgerSeq in maybeMergeRoTTLBumps. 3. InMemoryLedgerTxn missing move overloads for createWithoutLoading The new InternalLedgerEntry&& overloads of createWithoutLoading and updateWithoutLoading were added to LedgerTxn but not overridden in InMemoryLedgerTxn. When called with a LedgerEntry temporary, the move overload was selected via implicit conversion, bypassing InMemoryLedgerTxn's updateLedgerKeyMap() that tracks offers for SQL. Fix: add move overloads to InMemoryLedgerTxn that extract the key before forwarding via std::move. Regenerate protocol-25 ledger close meta golden files to reflect the corrected TTL bump behavior.
