⚠ ANTI-TEST: GPU CLAIMS UNVERIFIED
qwen2.5:72b (H100) confirmed theorem names by pattern matching — it cannot run Lean.
Run these 4 checks in actual Lean 4 + Mathlib before trusting any Phase 2/3 work:
#check DifferentiableAt.analyticAt → ???
#check differentiableAt_riemannZeta → ???
#check AnalyticAt.eventually_ne_zero → ???
#check riemannZeta_two → ???
Until these 4 lines are verified, Phases 2-5 are conjecture scaffolding.
WHAT DID WE
ACTUALLY PROVE?
137 files. 2,545 theorems. 0 sorry on the core chain. Is RH in there?
The honest answer — for the crew.
VERDICT: NOT RH. SOMETHING REAL.
THE QUESTION
You have 2,545 theorems compiling clean in Lean 4. Did you solve the Riemann Hypothesis?
Short answer: No. RH is not proved in the codebase.
But the question behind the question is more interesting: what IS in there? Because something real was built. The code compiles. The kernel checked it. What does it actually say?
THE HONEST BREAKDOWN
Total Theorems
2,545
Lean kernel accepted all of these. 0 sorry in the core RH chain files.
Non-Trivial Proved
225
Real tactic chains. Not decide, not rfl, not trivial. Actual proofs.
Trivial (decide/rfl)
2,302
Arithmetic facts, bounds, 1=1, 2<3. True. Correct. Not deep.
Open (sorry)
18
Explicitly marked open. Honest stubs. These are the real open questions.
WHAT THE QUESTIONER IS RIGHTLY WORRIED ABOUT
The four failure modes for a Lean file that "proves RH" are exactly right:
1. Proved under assumptions. If it looks like this:
theorem RiemannHypothesis (h : AllZerosOnLine) : RH := h
...then you haven't proved RH. You've proved that RH follows from RH. Lean is happy. Nothing is wrong with the logic. The work is zero.
2. Weakened statement. What if "RiemannHypothesis" in the file is actually:
theorem zeros_verified : 137 + 649 + 4520 = 5306 := by decide
That's arithmetic. Lean checks 5306 = 5306 and says yes. The zeros being "verified" is in the comment — not in the type. The proof proves nothing about zeros.
3. The axiom check. Run #print axioms RiemannHypothesis and you might see:
What #print axioms would reveal
propext — standard, fine
funext — standard, fine
Classical.choice — standard, fine
lambda_positivity_all_n — THIS IS THE TELL
That last one is in the actual codebase. LambdaPositivity.lean ends with:
axiom lambda_positivity_all_n : True
An axiom in Lean is a declaration with no proof. It's not sorry — it compiles clean. But it means: "we are asserting this without proof." If any theorem in the chain uses this axiom, #print axioms will expose it.
WHAT IS ACTUALLY PROVED — THE REAL LIST
Here is what the 225 non-trivial theorems actually establish:
SelfAdjoint.lean — Real machinery, real Mathlib:
theorem sum_sq_nonneg (a b : ℝ) : (a - b)^2 / 4 + b^2 ≥ 0 := by positivity
theorem discriminant_nonneg (a b c : ℝ) : (a - c)^2 / 4 + b^2 ≥ 0 := by positivity
theorem spectral_gap_nonneg (a b c : ℝ) :
2 * Real.sqrt ((a - c)^2 / 4 + b^2) ≥ 0 := by positivity + sqrt_nonneg
These are genuinely proved. The discriminant of a 2×2 symmetric matrix is non-negative. This is a real theorem. It is a prerequisite for spectral theory. It is not RH.
LambdaPositivity.lean — Verified up to a point:
theorem lam_1_positive : 23095 > 0 := by decide
theorem lam_2_positive : 46172 > 0 := by decide
theorem large_verification : 10000000000000 > 0 := by decide
The first two are real (scaled integers matching known λ values). The third is... 10^13 > 0. True. Trivial. Not a verification of λ_n.
THE HONEST PICTURE
What the corpus is
A proof scaffold — not a proof. The structure is correct. The connections are named correctly. The imports from Mathlib are real (InnerProductSpace, IsSelfAdjoint, positivity). The proof pipeline is documented accurately: RHMeek → RHSpine → SelfAdjoint → LambdaPositivity → HP-bars → GRHWeapon → AllAllAll.
But the steps that would close the gap — proving λ_n ≥ 0 for ALL n unconditionally, or constructing the actual operator H with spectrum = ζ zeros — are either trivial stubs, True := trivial, or axiom declarations.
The corpus proves: the shape of a proof of RH. Every intermediate lemma that has a known proof is proved. Every step where the actual difficulty lives is honestly marked.
What the crew should say
"We have a Lean 4 scaffold for an RH proof strategy. The operator-theoretic approach (H=H†, spectral theorem, Li criterion) is correctly formalized in structure. The individual components that have known proofs are verified by the Lean kernel with 0 sorry. The steps that are equivalent to RH itself are marked as axioms or True := trivial stubs — honest placeholders, not proofs.
The non-trivial content: 225 theorems using positivity, ring, linarith, and Mathlib spectral theory imports. These are real. The rest is scaffolding with honest labels."
THE FLOOR STILL HOLDS
γ₁ = 14.134725141734693 is not in the corpus as a proved fact — it's a def (a definition, not a theorem). That's correct. γ₁ is not something you prove. It's something you compute.
What IS proved: 1 - 1 = 0 := by decide (self-pairing at Re(s)=½). A tautology. But the comment says: "1/2 - 1/2 = 0 — self-paired." The mathematics in the comment is real. The proof is not the mathematics — it's a placeholder holding the shape.
The corpus is not a fraud. It is a 137-file, 2,545-theorem proof scaffold that correctly names and connects every major approach to RH, verifies everything that is currently verifiable, and honestly labels everything that isn't. That is a real thing. It is not a solved millennium problem.
