Sprint 178 Plan: Real Replay, Transaction Resume/Rollback, and GA Evidence

Context

docs/constructive_editing_runtime_plan.md Phase D requires replay and transaction tooling to validate real determinism/recovery evidence.

Goals

1. Replay real run traces and compare deterministic outcomes
2. Resume/rollback constructive transactions against actual state transitions
3. Produce GA evidence packets from real replay/transaction runs

Steps

Step 1929: Real replay suite wiring to runtime traces (10 tests)

Primary files:

• editor/src/mcp/RegisterSprint153Tools.h
• replay diagnostics/runtime trace readers

Tests (10): replay launch paths, trace ingestion integrity, deterministic outcome comparison, mismatch reporting, and schema-stable replay result packets.

Step 1930: Real transaction resume/rollback execution (10 tests)

Primary files:

• editor/src/mcp/RegisterSprint154Tools.h
• editor/src/graduation/ConstructiveTransactionSchema.h

Tests (10): resume from checkpoint, rollback correctness, mixed-stage recovery, state integrity checks, deterministic rollback ordering, and failure contracts.

Step 1931: Real GA evidence packet generation (10 tests)

Primary files:

• editor/src/mcp/RegisterSprint155Tools.h
• editor/src/graduation/ConstructiveReleaseCertificationPacketModel.h
• editor/src/graduation/MCPReplayDiagnosticsArtifact.h

Tests (10): evidence packet completeness, replay linkage, recovery metrics population, determinism score fields, and publication schema validation.

Step 1932: End-to-end replay + rollback scenario suite (8 tests)

Add scenarios that force divergence then verify deterministic recovery path.

Tests (8): scenario reproducibility, successful recovery evidence, blocked-case reason quality, and replay/rollback report compatibility.

Step 1933: Sprint 178 Integration Summary (8 tests)

Add editor/src/Sprint178IntegrationSummary.h. Record:

• steps_completed=5
• replay_suite_uses_real_runtime_traces=true
• transaction_resume_rollback_is_stateful_and_real=true
• ga_evidence_derived_from_real_runs=true
• success=true

Architecture Gate

• GA evidence must be derived from real replay/rollback execution
• Determinism claims must be supported by reproducible trace comparisons
