Sprint 198 Plan: Long-Range Edit Reliability III (Execution)

Context

Need transactional execution engine for long-range plans.

Goals

1. Execute long-range plans transactionally
2. Support partial failure rollback
3. Persist deterministic execution traces

Steps

Step 2029: Transactional long-range executor (10 tests)

Execute graph-ordered edits with transaction boundaries.

Step 2030: Partial failure rollback engine (10 tests)

Rollback to nearest deterministic checkpoint on failure.

Step 2031: Multi-file conflict detection during execution (8 tests)

Detect and classify cross-file edit conflicts.

Step 2032: Execution trace and recovery packet export (8 tests)

Persist per-node execution and rollback traces.

Step 2033: Sprint 198 Integration Summary (8 tests)

Add editor/src/Sprint198IntegrationSummary.h.

Architecture Gate

• Long-range execution must be transaction-safe with deterministic rollback.
