**F1 — Tier.** T0 (mathematical theorem — Noether’s first theorem).

**F2 — Sources.** 
- Noether, E. (1918). “Invariante Variationsprobleme.” Nachrichten von der Gesellschaft der Wissenschaften zu Gottingen, Mathematisch-Physikalische Klasse, 235–257.
- Lie, S. (1888–1893). Theorie der Transformationsgruppen. 3 vols. Leipzig: Teubner.
- Gauge theory framework: Weyl, H. (1918). “Gravitation und Elektrizitat.” Sitzungsberichte der Preussischen Akademie der Wissenschaften, 465–480; Yang, C.N. & Mills, R.L. (1954). “Conservation of isotopic spin and isotopic gauge invariance.” Physical Review, 96(1), 191–195.

**F3 — Domains.** Core physics — classical mechanics, electromagnetism, general relativity, quantum field theory, particle physics.

**F4 — Scale.** All scales where physical law applies.

**F5 — Falsifier.** n/a (mathematical theorem). Noether’s theorem is proven; it cannot be falsified. The physical applicability — whether nature’s Lagrangians carry the required symmetries — is an empirical matter, but the theorem itself stands.

**F6 — Rival (strongest form).** The symmetry-conservation link is a mathematical identity, not a physical claim. It tells us nothing about which symmetries nature actually possesses — it merely formalizes the consequences of symmetries we posit. The deep question is why nature has the symmetries it does; Noether’s theorem answers the consequence, not the cause. (Wigner 1967 Symmetries and Reflections; standard position in philosophy of physics.)

**F7 — Independence.** Mathematical proof — universal by construction. The theorem applies wherever the premises (action principle + differentiable symmetry) hold. Independence is not at issue; this is a T0 node.

**F8 — Pattern type.** Mathematical.

**F9 — Maps.** A1 (foundational structure), A3 (pattern-dynamics).
