• Adds an interim (phase 1) FTA for Communication.ReturnsWrongFreeSampleCount with a single root cause, which moves the failure mode from [MISSING] to [OK] in the traceability report.
• Following the agreed approach, this is a "case 3" dummy FTA, because the original analysis states the failure mode is fully covered by one preventive measure; the detailed FTA and the measure-to-root-cause link follow in phase 2.

Before (main)

• [MISSING] TRLC Failuremode Communication.ReturnsWrongFreeSampleCount: missing reference to Root Causes
• root causes: 0

After (cd_add_fta_wrong_sample_count)

• [OK] TRLC Failuremode Communication.ReturnsWrongFreeSampleCount → mw_com_fta.RootCauseReturnsWrongFreeSampleCount
• [PARTIAL] TRLC Rootcause mw_com_fta.RootCauseReturnsWrongFreeSampleCount (no safety measure linked yet)
• root causes: 1
• Overall report: MISSING 64 → 63, OK 143 → 144, no regressions
