What We Can Conclude
The synthesis: bounded mathematical findings, open obligations, and the novelty question, adding no new evidence and wrong wherever an earlier chapter is wrong.
Thirty chapters ago, the book asked whether “Lorentz boosts preserve the interval” is true, and answered that it depends on which sentence you mean. This chapter collects what the book can now say, in the vocabulary of the earlier chapters: the bounded findings, the obligations still open, and the question of whether any of it is new. It adds no new capability.
What has been established
In the mathematics (kernel- or computation-checked)
| Claim | Strongest recorded standing | Where |
|---|---|---|
Algebraic Lorentz interval invariance (γ²(1−v²)=1) |
formally_verified in Lean and Rocq; Z3 unsat (computation); hosted dossier source_claim_qualified for the project-owned source claim |
Ch. 20 |
Gamma bridge (γ = 1/√(1−v²), |v|<1 ⟹ γ²(1−v²)=1) |

Ch. 11, 12, 20 |
| Composed physical Lorentz theorem (1.1.0) | Kernel-accepted in Lean and Rocq (R4 source/audit bundle); not migrated into the accepted report, which still records 1.0.0 as computation_verified_within_stated_domain (SymPy only) |

About process (engine behaviours that held)
- Evidence is bound to an exact claim fingerprint, and a changed claim does not inherit old evidence (Ch. 1).
- Missing tools are
not_installed/not_evaluated, never a pass (Ch. 3, 13, 14). - Placeholders, unexpected axioms, and kernel rejections are caught by three independent guards (Ch. 3, 11).
- Conclusions are recomputed by fixed precedence from the records, with no tool vote and no score (Ch. 6).
- Failures, including the project’s own failed hosted runs and a corrected first implementation (P5-R1), are preserved (Ch. 8, 25, 28).
About an external record (P8)
For one pinned external Lean formalization record, the engine established a vector,
not a verdict: the challenge wrapper has a sorry (interface scope), the separate
solution theorem is kernel-accepted with a standard axiom set, the executed Comparator
accepts the configured mapping, the catalogue and documentation disagree, statement
correspondence is qualified, and proof digestion and historical correspondence are
not_evaluated. Neither dismissal nor full verification is justified (Ch. 28).
What has not been established
| Item | Standing |
|---|---|
| Cross-kernel semantic equivalence of Lean’s and Rocq’s reals | not_established (L3, Ch. 12/15) |
| Historical Euclid I.47 | not_evaluated; the modern theorem does not qualify it (Ch. 25) |
| Fidelity of the Euclid transcription to the page, and of the page to the Greek | not_evaluated (Ch. 25) |
| Any claim-bound Isabelle or SageMath result | Illustrative Docker checks only; no engine EvidenceResult (Ch. 13, 14) |
| Human proof digestion, anywhere | not_evaluated |
| Independent reproduction beyond the project’s own control | not_evaluated (Ch. 29) |
| Whether either repair is “right,” or accepted by anyone | not_decided / not_claimed (Ch. 27) |
| Anything empirical about relativity | No evidence layer exists (Ch. 4, 18) |
| Three-dimensional Lorentz group, tensors, curvature, field equations | No engine work (old-outline chapters 23–28, not written) |
| Any published criticism of any theory | None ingested (Ch. 23) |
| Experimental evidence | None (old-outline chapter 34, not written) |
Open obligations, in rough order of cost
- Report migration (R4). Move the accepted MATH01 report to physical claim 1.1.0, so the report and the kernel proofs say the same thing.
- Human review. A person reads the proofs, the transcription, and these drafts. This is the cheapest high-value step and nothing else substitutes for it.
- Bibliography. Entries now exist for the historical sources (Einstein, Lorentz, Minkowski, Heath), the tools and the Cannon background, but most were added as grounding and have not been read closely. Still missing: the reproducibility literature, the paper whose theorem P8 formalizes, and specific documentation pages for the tool behaviours the book relies on.
- Turn illustrative tool runs into evidence. Rocq and Isabelle compiled in
Docker examples, and Sage ran illustrative computations (Ch. 12-14). Add the
adapter and
EvidenceResultrecords, and decide which repaired sources may be promoted through a versioned evidence update. - Close the SymPy domain gap. The recorded
|v|<1domain is not enforced by SymPy (Ch. 9); change the status wording or the domain field in a new claim version. - Independent reproduction (R4). One outside party following the guide (Ch. 29).
- Cross-kernel correspondence. P9’s hosted record reports
structurally_consistentfor the algebraic pair; formal equivalence remainsnot_established, and the gamma-bridge coverage case isinconclusive. P10-A is a local-only abstract-ringequivalent_under_mappingcertificate. P10-B is local-only concrete correspondence under mapping for the designated 1.1.0 gamma and physical targets. No concrete real-model equivalence is established. - A real challenge case. Choose a published criticism and run the anatomy of Chapter 23 on it, with the faithful-reconstruction rules.
- The empirical layer and Part III’s later chapters. Large, separate programmes.
The novelty question
Is any of this new? The record answers what it can.
- The project’s landscape note says Physlib already contains a Lorentz-group definition, boosts, and rotations in Lean, so MATH01’s 1+1 identity “is a qualification example, not a claim to have newly formalized Lorentz invariance.”
- A targeted search found no equally direct maintained Rocq or Isabelle project for this exact theorem, which the note itself calls “a search result, not proof that no such formalization exists.”
- The P8 source note disclaims novelty for the conjecture, the formalization, the Comparator, and MathVet, and describes the project’s contribution as “a hypothesis-driven method, not a claim of novelty or acceptance.”
So this book makes no novelty claim. If a claim is later made, it would have to be for the method (evidence-first contracts, bounded conclusions, preserved failures) and would need a systematic literature search of the kind the landscape note lists as an immediate obligation. The mathematics is textbook.
What the book can responsibly say
A sentence that survives every status above: In a small, fully specified model, a Lorentz boost preserves the interval (checked by two proof kernels), a tempting alternative does not (checked by two solvers), and for a handful of related statements the engine can say precisely what was checked, by what, and what remains open. It does not say relativity is true, that anyone’s criticism fails, or that the formalizations mean what their prose says.
What this establishes
The project’s evidence is strong on a narrow band and says nothing outside it. That is the intended result: the method’s value is the discipline about which band a sentence belongs to. A reader who leaves able to ask of any mathematical claim “which claim, which version, which tool, which assumptions, and what remains open?” has what the book set out to give.
Human review of the book itself: none is recorded.
Try it yourself
Re-derive this chapter’s tables from the repository: the accepted report
(artifacts/math01/report.md), the R4 bundle (artifacts/math01-r4/), and the P6,
P7 and P8 evidence records. A discrepancy between this chapter and those records
means this chapter is wrong.
Open questions.
- Is “no novelty claim” the right stance, or does the method deserve a claim that a literature search would test?
- Which of the nine open obligations should block publication of a first edition, and which can follow it?
- If a reviewer found a flaw in the shared statement of the algebraic theorem, how many rows of the first table would change?
