Release 0.203

v0.203.0 — 2026-07-25

The formulas workbench. /formulas becomes a place you can author a calculation, not only read one: a signature calling-contract (signatureOf — what must I hand this formula, per target, statically), a guided editor with a live in-browser validation rail over one form+YAML draft, sharing a formula as a /s live calculator (static equations + warnings render with no JS; only the calculator is an island), Euler the mathematician specialist, and five instructional seed formulas that double as the arithmetic regression suite.

Carries two pre-existing fleet-wide fixes found en route: copied share links pointed at the client origin (which does not serve /s — broken for every node type since the member carve), and client/web Tailwind never scanned packages/web-ui, so every Switch and Checkbox rendered with no checked state (full entry).
