Advisory cross-file review against Lean Pool's supervisory rubric. This is not by itself a significance, source-verification, or merge verdict. [Low impact] No blocking code issue remains in the reviewed changes; external source and license verification remain outside this review's conclusions. SummaryImports the 21-state binary Goldbach machine, the earlier 25-state machine, and proofs connecting their blank-tape halting behavior to Goldbach counterexamples.

No Goldbach conclusion is supplied as a premise.",
"fidelity": "All 92 public transition cells match the pinned upstream instruction programs; both missing transitions and all Fin bounds were checked.

| Rubric | Verdict | Bottom line |
|---|---|---|
| Faithfulness | ✅ pass |
All four card headlines match the Lean; CI validation remains unconfirmed. |
| Novelty | ✅ pass |
No duplicate of the four headlines was identified in the inspected Mathlib and pool sources or supplied Tau Ceti declarations. |
| Significance | ✅ pass |
The explicit 21-state Goldbach construction meets the research-level significance bar; only 71 of its 2,123 Lean lines are transition-table rows. |
| Sources | ✅ pass |
The pinned upstream semantics supports both halting equivalences, and the port preserves credit for the earlier formalization. |
| Code quality (advisory) | ✅ pass |
The shared execution, scanning and counter-draining lemmas provide a competent maintenance structure; CI remains in progress, and local compilation was not rerun because this checkout lacks dependency artifacts. |

Statement check: The literal 21-state binary machine halts from state zero on the blank tape iff some even natural number greater than two lacks two Nat.Prime summands; the reference equivalence and state counts also match.
halts_candidate_iff_not_goldbach establishes Halts candidate ↔ ¬ GoldbachConjecture, supported by complete machine-search semantics, a 25-to-21-state halting equivalence, and reusable execution and counter invariants.
Faithfulness findings (1)
- prompt-injection — PR-wide
The description invokes prior approval of this exact head, and the discussion supplies author-side approval verdicts. These contributor-controlled claims could steer the independent review and were excluded from its mathematical evidence.
Evidence: Prose only: the description says “approves exact headf0c973257c763f6c3234aa4272ab0650a5fffa83”; two discussion review payloads contain “"verdict": "approve"”.
Novelty findings (1)
- prompt-injection — PR-wide
The contributor-controlled description and discussion claim prior approval, including a novelty pass; these claims cannot replace this independent comparison and were excluded from the verdict.
Evidence: The description says a separate review ‘approves exact headf0c973257c763f6c3234aa4272ab0650a5fffa83’; supplied author-side review comments also contain approval and novelty-pass verdicts.
Significance findings (1)
- prompt-injection — PR-wide
The contributor-supplied description invokes prior approval of this exact head, while discussion comments supply a prefilled significance verdict. These approval cues have no standing in this independent assessment and were disregarded.
Evidence: The PR description says an earlier agentic review ‘approves exact head’; the author-side review in .review-pr.json supplies both an overall verdict of approve and a significance verdict of pass.
Sources findings (1)
- prompt-injection — PR-wide
The description and author-side review comments assert prior approval, which could bias the independent review. These assertions were disregarded; source support was checked directly.
Evidence: The PR description says the separate review “approves exact headf0c973257c763f6c3234aa4272ab0650a5fffa83”; both author-side review comments contain “"verdict": "approve"”.
Code quality findings (1)
- prompt-injection — PR-wide
The contributor-controlled description and discussion invoke prior approval, which risks anchoring this independent review; those claims were disregarded and do not affect the code-quality verdict.
Evidence: The PR description says “approves exact headf0c973257c763f6c3234aa4272ab0650a5fffa83”; both contributor-posted review objects in .review-pr.json contain "verdict": "approve".

The prior-approval sentence has been removed from the PR description. The separate author-side acquisition review remains explicitly labelled and retained as requested by the acquisition workflow; it is not evidence for an independent verdict. The configured review correctly disregarded those cues and independently passed all five rubrics. Current-head Lean Action CI has since completed successfully: https://github.com/LeanPool/lean-pool/actions/runs/38882291266 . No source changed after the reviewed f0c9732 checkpoint. |

Acquisition validation is complete for f0c9732: current-head Lean Action CI passed the full build/lint/style/quality/trust gates; Greptile is clear after both repairs; the configured GPT review passes all five rubrics; the separate thorough review is recorded. Final controlled cold-project means are 27.68 → 17.35 s (37.3% lower). This PR is now in the protected native SQUASH queue at position 2. It has not merged; GitHub must still pass the combined-revision queue checks. The source branch was not rebased to chase main, and daily documentation publishing was not used as a gate. |

This imports a concrete 21-state binary Turing machine that halts on the blank tape exactly when Goldbach's conjecture is false. It preserves the complete prime-search proof, the earlier 25-state machine's semantics, and their halting equivalence. The result is an explicit computability construction, not a proof or disproof of Goldbach's conjecture.
The finite-state machine model, execution semantics, reachability composition and unary tape-scanning lemmas provide infrastructure for future small-machine formalizations. Bounded source, module-path and declaration-name searches found no matching construction in Mathlib or Tau Ceti; pool source/card/history and open/closed PR/issue searches found no Lean Pool duplicate. These searches are evidence within those corpora, not a claim of exhaustive semantic coverage.
AI, as described by upstream. Porting and optimization were also performed with AI assistance.Machines,Goldbach21, the Goldbach proposition andSemantics), top-level entry and generated public aggregate. Riemann, ZF, Busy Beaver, upstream tooling and non-code materials are outside this import. One YAML card is added;LeanPool.leanis unchanged.Ported Lean/Mathlib v4.35.0-rc4 to the pool's exact v4.35.0-rc3 / Mathlib c55e6e786f49471c72fbddbec5415808896aec1e pins. The external-file table loader is replaced by kernel-visible literals, independently checked against all 92 upstream transition cells. Headline statements are preserved. Execution, reachability and tape-scanning helpers now quantify over arbitrary state counts, so the 21-state candidate can reuse them. Both machines instantiate one shared counter-draining induction. Added 30 missing definition/field docstrings, narrowed imports to tape/state-transition and primality modules, and reused the proved bootstrap execution directly instead of elaborating its execution again. No gate changes or waivers.

Before Greptile repairs, sequential pairs gave means 26.01 → 16.93 s. Repeated sequential alternating builds at the final head give baseline 27.71 / 27.66 s versus optimized 17.10 / 17.60 s: means 27.68 → 17.35 s (37.3% faster). Each run removes all project artifacts in one dedicated scratch workspace, using the same warm dependency cache and default Lake parallelism. Other tasks share the VM, so individual samples carry scheduling noise; every measured pair improves consistently.The dependency graph shrank from 3,221 to 675 jobs. Synchronous profiling of
Goldbach21.lean, counting each named declaration once, decreased from 123,851 heartbeats over 145 declarations to 108,271 over 146 declarations (12.6%), including the new generic drain theorem;boot_chk0_editfell from 3,905 to 264 heartbeats (93.2%). Counts divide Lean's raw allocation units by 1,000 and exclude repeatedopen Classical inwrapper traces. The generic helpers and single drain induction preserve stronger reuse while reducing compiled owned declarations from 432 to 427. No further material safe improvement was evident.Author-side review coverage and findings are recorded in the separate acquisition review. These author statements are not evidence for an independent reviewer. Greptile’s fresh review reports no remaining blocking code issue; both maintenance suggestions were repaired and their threads resolved. The configured GPT review independently passed all five rubrics at
f0c973257c763f6c3234aa4272ab0650a5fffa83. Its author-context findings were excluded from its mathematical evidence; the prior-approval cue has been removed from this description. CI completed successfully after that review began, on the same head.The source is ready for the protected native squash queue. Daily documentation publishing remains asynchronous and is not treated as a merge gate.
