* Nastran bulk data writer: fixed-format entries, exact large-field reals, SOL 101/103 decks Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Nastran writer tests: golden decks, a re-reader of our output, node order against Nastran's conventions Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * docs: Nastran writer in the roadmap, parity table and deck notes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Nastran writer: simplify planning (subcases, one property table), stream cards into the deck, write through the VFS ElementKind::corner_count/is_quadratic and Dofs::bits/from_bits join the model. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Nastran joins the shared deck formats; deck.write chooses steps for every format nastran::write_resolved is the FORMATS row; Format::write_steps and with_steps write a subset of steps (a Nastran run is static or frequency steps); problems go through the shared unsupported().
