Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review. 📝 WalkthroughWalkthroughThe change pins the delegation API dependency to a specific revision. It adds recovery errors and account-size retrieval for finalize tasks. Finalize and undelegate tasks now carry account data sizes. Preparation tasks generate typed preallocation instructions, and delivery preparation sends them in chunks before buffer preparation. The change renames preparation-task APIs, centralizes transaction error mapping, and adds integration coverage for oversized and mixed-size accounts. Assessment against linked issues
Suggested reviewers: Merge Risk: 🟡 Moderate · up to The PR enables larger account commits through preallocation, but the current implementation retains a public path that can panic and may overload the RPC endpoint with large strategies; it also documents Undelegate support that is silently skipped. These issues should be fixed or explicitly accepted before merge. ✨ Finishing Touches🧪 Generate unit tests (beta)

`@magicblock-committor-service/src/transaction_preparator/delivery_preparator.rs`:
- Around line 135-140: Introduce a dedicated PreallocateTransactionErrorMapper
and preallocation-specific error variant, then update the preallocation
send/error path in DeliveryPreparator to use them instead of BufferErrorMapper
and InternalError::BufferExecutionError. Ensure AccountAlreadyInitialized and
retry classification follow preallocation semantics, and replace both related
TODOs.
- Around line 309-311: Remove the public preallocate_account method and its
todo!() stub from DeliveryPreparator; callers should use the existing
preallocate method that performs the account preallocation work.
In `@test-integration/test-committor-service/tests/test_delivery_preparator.rs`:
- Around line 115-123: Update the buffer_tasks[2] setup around the
BaseTaskImpl::Commit match to panic explicitly when the task is not a Commit
variant, while preserving the large_pubkey assignment for the matching case.
In `@test-integration/test-committor-service/tests/test_ix_commit_local.rs`:
- Around line 609-620: Update both test_ix_commit_finalize_3_large_1_small and
the corresponding test around the second commit_large_accounts call to pass
CommitIntentKind::CommitFinalize instead of CommitIntentKind::Commit, ensuring
the tests exercise finalization and delegated-account preallocation while
preserving their existing inputs and strategy assertions.
In
`@test-integration/test-committor-service/tests/test_transaction_preparator.rs`:
- Line 6: Update all five FinalizeTask fixtures to include the required
state_size field, using each fixture’s corresponding account data length;
preserve the existing fixture values and behavior.

214-224: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winBound concurrent preallocation sends.
Line 224 polls every preallocation chunk at the same time. The number of outstanding RPC requests grows with the strategy size. Each failed send can also retry up to three times. Large strategies can overload the RPC endpoint and fail delivery preparation.
Process chunks in bounded parallel batches.
Proposed fix
- let iter = chunked_ixs.iter_mut().map(|el| { - self.send_ixs_with_retry( - el, - authority, - 3, - uniqueness_nonce, - PreallocateErrorMapper, - ) - }); - - join_all(iter).await.into_iter().try_for_each(|el| el) + for batch in chunked_ixs.chunks_mut(MAX_PARALLEL_BUFFER_SENDS) { + let sends = batch.iter_mut().map(|instructions| { + self.send_ixs_with_retry( + instructions, + authority, + 3, + uniqueness_nonce, + PreallocateErrorMapper, + ) + }); + try_join_all(sends).await?; + } + Ok(())🤖 Prompt for AI Agents

What changed
This PR enables commits & finalizations of account with size diff over 10kb from committed size. Prior this failed with allocate errors as there's an SVM limit on allocation per instruction per account.
This PR integrates dlp preallocate logic that prepares account size in advance.
Closes #878
