Community Relevance — why this belongs in Echopedia

• Tier D (ruled 2026-10-19, card t_18d620b8). The story is about TSMC, not about us: the community is not a party to a corporate capacity announcement (Chair C.C. Wei 魏哲家, Q3 earnings call; additional 3nm fab in Tainan Science Park, H1-2028 ramp). The digest’s own tie_state gate returns unknown for this story — no vault page for TSMC or 魏哲家, and the archive’s 台積電 mentions are third-party reporting reprints (taiwanjustice corpus) plus Arizona demographic context about the Phoenix fab, a different story. Cited here as current-history reporting only; no subject page minted. The original Community Relevance line was unconditional mint boilerplate, not a ruling.
