  phase_10_status='completed; G4 deviation resolved (0 SILENT_SWALLOW + 0 UNCLEAR + 0 migration-target in 37-file scope)'

- tracks.md: sub-track 6d-2 now shows shipped with 75/76 sites migrated,
  Phase 10 complete, G4 deviation resolved.

After Phase 10:
- 0 INTERNAL_SILENT_SWALLOW in 37-file scope (was 27)
