Combined commits no longer need separate executor implementations for single-stage execution, the first transaction of a split execution, and the subsequent actions or undelegations. Replace their duplicated retry loops and timeout adapters with one transaction executor. - Track the current strategy, an optional pending strategy, the confirmed commit signature, and the current attempt count in one concrete runner. Remove SingleStageExecutor, TwoStageExecutor, Initialized, Committed, the sealed trait, StageExecutor, and its three adapters. - Route selected strategies through execute_strategy. Borrow the existing authority, clients, preparator, callback scheduler, and committed-account list instead of cloning services or rebuilding the account list. - Preserve nonce, action, and undelegation recovery according to whether the commit has already landed. Keep execution-limit fallback splitting after the last combined commit and propagate recovered uniqueness nonces to the pending transaction. - Keep the ten-attempt recovery limit per transaction. Preserve attempts consumed before a timeout, resetting the count only when advancing to another transaction or switching to split execution. - Apply the existing intent-wide callback deadline to the shared loop, including callbacks in the pending transaction. Report each successful transaction's callbacks before preparing the next transaction and retain the existing callback behavior for preparation and recovery failures. - Reuse the confirmed commit signature when removing failed follow-up actions leaves no work. Preserve the failure when undelegation recovery empties the transaction, and prevent whole-intent retries after a known successful commit. - Surrender current, pending, and replaced strategies for cleanup on terminal paths. Record recovery cleanup before awaiting blockhash-cache invalidation so cancellation cannot lose that cleanup information. - Move integration tests to the shared entry point and check callback timing at the next transaction's preparation boundary. Add six focused unit tests covering timeout, retry counts, preparation and nonce-fetch failures, cleanup, and recovery after a confirmed commit. Keep transaction packing thresholds, result and error types, metric labels, persisted status/signature mappings, public intents, and buffer-close policy unchanged. Larger naming and persistence cleanup remains separate work. Validation: - All six transaction-executor unit tests passed. - Clippy with warnings denied passed for all committor-service targets and the test_intent_executor integration target. - Integration test targets compiled successfully. - Nightly formatting checks passed in both workspaces; git diff --check passed. - The devnet test_commit_id_actions_cpi_limit_errors_recovery test compiled but failed during fixture funding, before exercising the executor. Local RPC connectivity and the initial airdrop were unavailable in this session. - No performance benchmark was run. The refactor adds no production RPC calls or transactions; broader runtime coverage remains for CI.

Suggested reviewers: Merge Risk: 🔵 Low · up to The unified transaction executor appears to preserve the existing behavior. Two small follow-ups remain. The documentation should note that the commit and follow-up signatures can be identical when no follow-up transaction is sent. One integration test should reset its deadline so it does not fail intermittently when setup is slow. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Document that finalize_signature can equal commit_signature.
The new rustdoc says finalize_signature is the "Signature of the subsequent actions or undelegations." This is not always true. In TransactionExecutor::execute_current, a follow-up transaction can fail with ActionsError. If removing its actions leaves current.optimized_tasks empty, the executor returns Ok(commit_signature). No follow-up transaction is sent. ExecutionOutput::TwoStage then holds the same signature in both fields. persist_result stores that value as finalize_stage_signature. The integration test test_two_stage_action_failure_keeps_combined_commit asserts this behavior. Readers of the persisted signatures need this case documented.

Reset started_at before calling execute_strategy.
TestEnv::setup() starts the 60-second deadline before this test funds the payer, initializes the account, and builds the strategy. This direct execute_strategy call does not reset it. If those steps or execution use the remaining time, the timeout path reports TimeoutError and removes the actions. The test can then fail its assertions expecting an ActionsError callback and patched error.

Summary
Replace the separate single-stage and two-stage executors with one transaction executor. Keep follow-up transactions when needed, along with existing recovery, callback, retry, and cleanup behavior.
Closes #1768.
Stacked on #1764.
Breaking Changes
Internal Rust callers use
execute_strategyinstead of the removed executor types. Protocol and persisted data formats are unchanged.Test Plan
Six focused unit tests, targeted Clippy, integration compilation, and formatting passed. The devnet recovery test failed during fixture funding because local RPC was unavailable; runtime integration coverage remains for CI.
