- Service locator matches:
  - `src/Findings/StellaOps.Findings.Ledger/tools/LedgerReplayHarness/Program.cs`:95 var writeService = scope.ServiceProvider.GetRequiredService<ILedgerEventWriteService>();
  - `src/Findings/StellaOps.Findings.Ledger/tools/LedgerReplayHarness/Program.cs`:96 var projectionWorker = scope.ServiceProvider.GetRequiredService<LedgerProjectionWorker>();
  - `src/Findings/StellaOps.Findings.Ledger/tools/LedgerReplayHarness/Program.cs`:97 var anchorWorker = scope.ServiceProvider.GetRequiredService<LedgerMerkleAnchorWorker>();
  - `src/Findings/StellaOps.Findings.Ledger/tools/LedgerReplayHarness/Program.cs`:98 var logger = scope.ServiceProvider.GetRequiredService<ILoggerFactory>().CreateLogger("Harness");
  - `src/Findings/StellaOps.Findings.Ledger/tools/LedgerReplayHarness/Program.cs`:99 var timeProvider = scope.ServiceProvider.GetRequiredService<TimeProvider>();

### Fix Guidance
- Split files over 100 lines into smaller types or partials.
- Replace service locator usage with constructor injection.

## Testing Fullness Findings
- Status: PASS
- Expected layers: Unit
- Detected test projects: src/Findings/__Tests/StellaOps.Findings.Ledger.Tests/StellaOps.Findings.Ledger.Tests.csproj [Unit], src/Findings/__Tests/StellaOps.Findings.Ledger.ReplayHarness.Tests/StellaOps.Findings.Ledger.ReplayHarness.Tests.csproj [Unit], src/Findings/StellaOps.Findings.Ledger.Tests/StellaOps.Findings.Ledger.Tests.csproj [Unit]
- Missing layers: none

### Manual checks required
- Observability contract tests for WebService/Worker.
- Offline execution (tests must run without network access).

### Fix Guidance
- None.
