τ response: Structurally constrained
External: externally open
Verification: pending external review
The Corpus currently constrains, reframes, or materially supports an account of this problem.
Structural Challenge
This response is paired with its canonical Structural Challenge:
Yang–Mills Existence and Mass Gap
(CB-YANG-MILLS) in the
Mathematics Structural Challenge Ledger.
τ response
Registry evidence gives a direct Corpus account or constraint.
Evidence route
This response is supported by 5 canonical registry items in the τ Corpus.
Notes
The τ-internal mass-gap theorem IV.T75 closes kernel-only against Mathlib + native_decide alone — no custom-axiom dependency. The reason this Challenge Response carries a Structurally constrained status rather than Internally addressed is the bridge layer: the formal correspondence between the τ-formulation of Yang–Mills and the Clay Yang–Mills statement on ℝ⁴ is treated separately and not yet formally bridged via Lean. This is the same pattern as the Master Schema → classical Riemann Hypothesis split: a τ-internal kernel-only result plus an unproven bridge to the orthodox classical statement. See the Yang–Mills note on the Custom Axiom Inventory for the full split, and IV.T75 for the kernel-only theorem itself. The bridge layer is the program’s open work; IV.T75 is not axiom-dependent.
Verification
External-review boundary
External mathematical review of the τ formulation, comparison against orthodox proofs/disproofs, and assessment of the bridge between τ-internal results and standard mathematical statements.
Provenance
Status disclaimer
A Challenge Response reports the program's current internal stance against a canonical Structural Challenge. It does not imply external verification, scientific consensus, philosophical settlement, or final proof. Read it together with its evidence route, registry references, verification status, and external-review boundary.
