Subject and independence
Examination date: 2026-10-14 UTC. Reviewer: mathematical reviewer, GPT-6-astra, commissioned to refute the entire conclusion. The reviewer neither authored nor helped construct the frozen argument and had no exposure to it before this examination. Project examination work is attributed to Plasma AI. The source-record exposure described under Premises requires a distinct grader's materiality ruling; this report makes no ruling about its own eligibility or contract acceptance.
Frozen subject: the extraction frozen at
2026-10-14T17:08:39.381721Z. The full proof subject is the D1 mathematical
subsection preserved in
wiki/research/erdos_354/evidence/assets/dyadic_root_subject/argument.md,
including its imported premise and consequence sentence. The original catalog
statement and formulation come from
wiki/problems/additive_bases/E0354/_index.md. The examination covers every
integer , every real , every prescribed first index, every finite
deletion, distinct-value completeness, and the exact existential-base
consequence. It does not examine the universal-base question, a full E0349
classification, historical novelty, or another candidate proof.
All five preserved files below were read in full. Their unchanged extraction
bytes, including the uniform [cut] markers, are part of this record. The
public manifest records the
freeze date and source mapping. The argument snapshot itself is the assigned
public proof subject: it preserves the complete mathematical D1 subsection,
without the surrounding account. No inference is drawn from omitted text.

The mathematical read set was these files and their manifest, followed by the
two narrowly authorized current dependency paths listed under Premises.
The known over-read at the latter boundary is disclosed there. Operating reads
were the commissioned repository guidance: README.md; the Claims, Evidence,
Tiers, Naming and Project claims portions of docs/anatomy.md and its
introductory conventions; docs/verification.md; docs/evidence.md;
docs/approach_vetting.md; docs/math_authoring.md; docs/weaving.md;
campaign/AGENTS.md; campaign/guides/verification.md; and the Reading
section of campaign/guides/research.md, with the supplied operating context.
Their examples and links did not enlarge the mathematical read set.
An empty subscription table was checked before mathematical reading. No incoming inter-node messages, web results, author plans, sibling reports, or earlier examinations of this deduction were read. No source URL was opened. The subject remained fixed; it was not repaired or replaced. The independent reasoning and exact attack examples are retained below. There is no mathematical code or numerical sampling leg. The external proof was neither read in full nor replayed here.
Restatement
Write . For an integer , put , the positive real root, and for and . The single-ray assertion, including its strengthening, is:
Thus each integer value is used at most once. Allowing an integer lower bound merely leaves the nonnegative-index sequence unrestricted. In particular, the assertion covers either starting-index convention or and every later tail. Only integer deleted values matter; other deleted objects cannot equal a sequence value. A finite deletion of indexed occurrences is also allowed, by taking a tail beyond their indices. The proof below handles that deletion simultaneously with .
The threshold may depend on . In the frozen proof, and influence the preliminary choice , and the imported theorem then supplies . Completeness is eventual; there is no assertion about every small integer or a numerical uniform threshold.
The consequence under examination has the quantifier order
where and . Here completeness uses finite sets of positions in . The frozen argument actually claims this conclusion at the single fixed base for all positive , without the ratio restriction. This is distinct from a statement for every real base in . The catalog wording in the target snapshot does not decide between those formulations.
Weakest steps
1. A valid shift exists for all parameters
The root and floor arguments must hold for every , including composite , and for arbitrarily small . If with coprime positive integers , then . Consequently divides , so . But a positive integer has th power either or at least when , never . Hence is irrational. From and monotonicity of the th power on positive reals, .
Let , , and . Choose a nonnegative integer so large that
Such a exists: for nonnegative integers , which is unbounded. One can require as well when using the starting-index convention . For every ,
The floor inequality follows from and . It follows that all the values with are positive, avoid , and are pairwise distinct. No estimate is asserted uniformly as grows or varies.
Set and . Both are positive, and is irrational: a rational nonzero reciprocal would make rational. These are precisely the hypotheses of the imported indexed theorem. In particular, the arbitrary coefficient introduces no exceptional arithmetic class.
This expands the frozen choice of and its elementary floor and root inferences. The explicit sufficient inequality for is a reconstruction of the stated “large enough” choice, not a different proof route or an added theorem premise.
2. The indexed representations really use distinct surviving values
Apply the imported theorem to these fixed . It supplies an integer threshold such that every integer has finite sets with
The theorem allows and to overlap. That causes no problem after the transport. The equalities give, exactly,
Each index map is injective. If their images intersected, then , so , impossible for an integer . Thus the finite union
contains each transported index exactly once, with every index at least . The equality of sums is therefore
The second equality uses the injectivity of on the chosen tail, proved in step 1. Without it, the equality of a sum over indices and a sum over values could fail. All these values lie outside .
Taking proves the restated conclusion. The order of choices is , then , then , then the representations for all . The chosen tail is independent of ; this is not a separate tail chosen for each desired sum.
For a finite set of deleted occurrences, increase the prescribed lower bound to . Every selected index then avoids as well. Deleting finitely many distinct values is already the arbitrary case. This supplies the claimed strong completeness under both conventions. It does not infer strong completeness from ordinary completeness: the source theorem is applied anew to the coefficients obtained after each deletion and shift.
The finite-set image and sum equalities, the explicit quantifier order, and the indexed-deletion specialization reconstruct the frozen argument's stated transport and “either convention” conclusion. No substantive missing lemma or replacement argument was found in these steps.
3. The existential consequence uses one fixed base
Take once and for all, so is fixed before and . For any , step 2 with and no deletions supplies representations by distinct values on the ray. If is the corresponding finite set of ray indices, then is a finite set of positions of with the same sum. It uses no position from the ray.
This proves the asserted consequence for every positive , irrespective of . Values shared by the two rays cannot invalidate a representation using only the first ray. The same representation also works if the two rays are viewed as a set of integer values. Changing the first index to is covered by the corresponding tail in step 1.
This is the exact inclusion argument behind “Adding the beta ray preserves completeness.” It preserves the required global existential quantifier. It does not provide a theorem for an arbitrary real : the proof specifically uses an integer with .
Strongest attack and exact failed witnesses
The strongest attack was that an indexed completeness theorem may rely on equal summands at different positions, making its transfer to distinct integer values invalid. This risk occurs inside the actual parameter family: at , the terms at indices and are both . Taking satisfies the source's irrational-ratio hypothesis, but the representation using both zeroth source terms repeats the value . Irrationality alone does not prevent the collision.
There is no general implication from indexed completeness to distinct-value completeness. As an exact auxiliary counterexample to that proposed shortcut, take two indexed copies of for every . Finite indexed sums represent every nonnegative integer by its ternary digits . Distinct values give only sums of different powers of and miss for every : a larger power already exceeds that integer, while
This auxiliary example is a counterexample to the generic shortcut, not to the commissioned theorem. The frozen argument does not use that shortcut. Its single shifted tail has pairwise distinct values, and the two transported residue classes are disjoint. The source theorem is applied only after those properties have been secured. Thus even a source representation choosing both ray terms at the same source exponent becomes a sum of distinct original values. The attack fails for the frozen proof for the exact reasons in steps 1 and 2.
A separate attack targeted the finite-deletion conclusion. Ordinary completeness does not survive arbitrary finite deletion: the values represent every nonnegative integer, but removing leaves only even sums and misses arbitrarily large odd integers. This is also an exact negative control for dropping : with , it is the very single ray under discussion. At that excluded endpoint the proposed source ratio is rational and the residue classes are not disjoint. For , the frozen proof instead changes the coefficients after the deletion and reapplies the theorem. It never assumes a deletion property of the source theorem. The negative control therefore does not refute the actual argument.
Further boundary attacks found no omitted case. The maximum of exists even when is empty, includes the zero boundary, and bounds every deleted integer value. A large and an arbitrarily large finite deleted value both affect before the source application. Very small or large can delay the increasing tail, but cannot prevent it because and . Dropping would be fatal: gives only zero sums. These boundary controls test hypotheses; none enlarges the theorem's domain.
The uniformity attack is also exact. No threshold can work for all finite deleted value sets: for any proposed common threshold choose an integer above it and delete . Every remaining nonnegative value is zero or exceeds , so is not representable. The frozen statement avoids that false uniform strengthening. No claim that a threshold must depend on each individual parameter separately is needed.
Finally, the consequence was attacked for reversal of and , and for accidentally applying the source theorem to the pair at base . Step 3 exhibits one fixed base; step 1 applies the source theorem at base to . Neither quantifier reversal nor wrong-base application occurs. No counterexample or unsupported essential inference was found in the commissioned conclusion.
Premises
Exact external interface and reading depth
There is one substantive theorem premise, derived from the actual proof and its consequence rather than from a list of citations:
for suitable finite . The finite sets may overlap and equal integer values in the two indexed rays may count separately. No strong-completeness, distinct-value, or smaller-base theorem is imported. The specialization is exactly , , whose hypotheses are checked in step 1.
The source is the accepted external result recorded as the first part of
E0354, with formal target Erdos354.erdos_354.parts.i and answer True.
The theorem's displayed type True ↔ P yields the required proposition
by its forward implication. The supplied definitions identify finite sets of
interleaving positions with the pair of finite exponent sets, by the maps
and . They identify “every sufficiently large
integer” with the eventual natural-number formulation without changing any
large positive target.
The source/version locator is Conjectures.io record
815c1d5f-3afb-4430-8e2c-260d9038f5b0, with the task, external source
versions, and ports identified in Task, Environment, and Port of
the preserved replay snapshot. The acceptance record reports a repository
rebuild on Lean v4.34.1 and an empty-environment kernel replay. The receipt
records its successful replay on 2026-10-14T01:08:29Z, target and statement
definition agreement, and exactly propext, Classical.choice, and
Quot.sound as target axioms. The site's own certification is not the basis
used here.
Reading depth is claims checked: the exact displayed theorem, its supplied definition interface, the permitted acceptance paragraph, and the replay record were inspected. The full imported proof is unread. The source statement snapshot and the replay snapshot identify different formal-conjectures version locators. Both explicitly describe the same mathematical indexed conclusion, and the current claim interface agrees with it. This examination does not assert byte identity between those two external versions or independently recheck their definitional closures; it relies on the identified acceptance and statement check for the replayed task.
This is the nonrecursive external-source boundary permitted by
docs/verification.md, Premises and source boundaries. The acceptance and
receipt support precisely the indexed premise used, at its recorded
accepted/formalized standing. They are not acceptance evidence for the new
dyadic-root deduction. The absence of a fresh imported-proof audit or replay
is explicit, not a stronger theorem assumed silently. The elementary root,
growth, floor and finite-set arguments are rederived above. No native L-claim
is consumed, and no native ledger row or native tier is imported.
Current dependency reading and exposure
At final filing on 2026-10-14 at 17:49 UTC, the then-current commissioning revision was resolved, and the following two paths were read at that same revision, without synchronization:
wiki/problems/additive_bases/E0354/claims/2026_09_11_jenw1n.md, the fieldsstatus,claim,scope,evidence, its Claim/Covers statement interface, and its first Acceptance paragraph.library/number_theory/conjectures_io_2026_lean_solutions_erdos_problems/evidence/verify/receipt_e0354_815c1d5f.md, the supplied replay receipt path.
The permitted metadata reads status: accepted, claim: proved,
scope: partial, and evidence: [formalized]. “Partial” limits the source
claim to the first, base- question; its Covers paragraph explicitly
excludes strong completeness, the set-union formulation and the second
question. These exclusions agree with the frozen interface and are respected
by the deduction. The four metadata fields and first Acceptance paragraph
match the frozen warrant; the current replay receipt's body matches the
preserved replay extraction. No difference in the consumed statement or
warrant, and no pending source acceptance, was found in the permitted fields.
Exposure during the dependency examination. At 17:31:12 UTC on the same date, the extraction of the current claim page selected whole labelled sections rather than only the permitted statement interface and first Acceptance paragraph. After the statement it displayed a source-proof description involving coefficient rescaling, binary digit criteria, and a joining/disjointness argument. After the first Acceptance paragraph it displayed additional site-certification, manual-review and prior-art claims; historical catalog-standing statements; a note concerning an unrun second kernel; and historical source-version retrieval and reconstruction statements. Those additional passages were outside the commissioned reading boundary.
The exposure was disclosed immediately to the commissioning party. A corrected selection at 17:32:57 UTC checked only the authorized interfaces and first Acceptance paragraph. No linked proof, source file or other review was opened. The additional passages are not used as a premise or as acceptance evidence in this report. Their materiality remains for a distinct grader to decide; this report does not treat the corrected extraction as erasing the exposure. The exact content categories and the point at which they were received are recorded here so that the ruling can address their possible influence.
Reproduction boundary
The five preserved snapshots and the derivations and attack witnesses in this report reconstruct the assessed deduction from an ordinary clone. Interpret relative links printed inside a verbatim snapshot against the original public path in its manifest; those printed links are not additional material examined here. The mathematical checks are the displayed exact inequalities, index maps, and positional-expansion witnesses. No computational rerun command or code is needed for them.
The imported receipt describes an earlier replay command and a solution and port with restricted holding. That command was not rerun; the solution, driver, port and underlying Lean proof were not inspected. The five-file package does not supply an ordinary-clone reproduction of that external replay. It preserves the prior acceptance warrant and its exact theorem interface, which is the external premise boundary of this examination. There is no new kernel or computational certification here.
Checklist
The following verdicts concern the complete D1 deduction and its stated consequence, with the external-proof boundary just described. “No defect found” records an examination result, not a grader's contract judgment. Every row applies to both conclusions. Steps 1–2 establish the single-ray statement with finite deletion; step 3 then uses it for the consequence, without an additional theorem premise.
Erdos-specific checklist
| Item | Verdict and reason |
|---|---|
| Quantifiers and scope | No defect found. Steps 1–2 fix one tail before all large targets and cover every . They assert eventual completeness, not coverage of all small integers. Step 3 fixes the base before both coefficients. |
| Circularity | No defect found. The external base- theorem has strictly the recorded interface; growth, injectivity and inclusions are proved without assuming the single-ray conclusion. No induction assumes completeness or termination. |
| Model and convention changes | No defect found. The index-to-value transfer is justified by two disjoint index maps and an injective tail. Both starting-index conventions and both finite-deletion conventions are accounted for. |
| Finite and statistical overreach | Inapplicable to the proof: no finite experiment, density estimate, averaging heuristic or statistical sample supports it. The attack examples above refute proposed shortcuts; no finite evidence is extrapolated to an infinite theorem. |
| Uniformity | No defect found. depends on the prescribed parameters, and the external threshold depends on the resulting coefficients. No numerical uniformity or exchange of limits is asserted. The arbitrary- uniformity counterexample is retained. |
| Extremal conclusions | Inapplicable. There is no sharp threshold, optimal base, infimum, supremum or attainment assertion. The fixed root is a witness, not an extremizer. |
| Consequences and composition | No defect found at the stated source standing. Source hypotheses, exact power identities, pairwise disjointness and positivity are established before composition. Step 3 separately checks the consequence. The universal-base reading receives no verdict. |
| Computation | Inapplicable to the new deduction. All arithmetic and examples are exact and exposed in prose. No numeric enclosure, range-enumeration result or executable checker is used. The external replay has only its recorded acceptance weight. |
| Reproduction | The noncomputational derivations and all five exact inputs are retained. No new rerun is claimed. The prior replay command and full external proof remain outside the execution and inspection coverage, explicitly recorded above. |
| Source and verdict fidelity | The permitted external statement, warrant and live interface agree at the strength used. No earlier verdict on D1 is imported. The source-record over-read is disclosed and requires independent materiality adjudication. The verdict words below are written in full. |
General canonical modes
| Mode | Explicit disposition |
|---|---|
| “Almost all” upgraded to “all” | Absent. The source gives every sufficiently large target; all parameter values satisfy the checked specialization. No exceptional parameter set is discarded. |
| Induction presupposing termination | Absent. Tail existence follows from an explicit unbounded lower bound for ; no search is assumed to terminate because completeness is desired. |
| Probabilistic or averaging heuristics treated as proof | Absent from D1. No claim about the methods of the unread imported proof is made. |
| Circular use of an equivalent statement | Absent. Neither the single-ray statement nor its existential consequence is a premise. Ordinary definitions of subset sums do not assert completeness. |
| Exceptional sets dropped from density arguments | Inapplicable. There is no density argument. Positivity and irrationality are verified for every chosen pair of source coefficients. |
| Finite verification treated as more than base-case coverage | Absent. The proof is symbolic for arbitrary parameters; the finite illustrative collisions are not cited as a universal verification. |
| Relaxed or averaged convergence substituted for the objects | Absent. Every transported term equals an actual floor term, and the finite index-to-value map preserves the sum exactly. |
Named patterns
| Pattern | Explicit disposition |
|---|---|
| Model-class transport instead of entailment | No model-class classification is used. The relevant convention transfer is an explicit injective sum-preserving map, not an analogy of formulas or terminology. |
| Uniformity over an infinite family from finite instances | Absent. The argument works for arbitrary with parameter-dependent choices, and no experiment supplies a uniform constant. |
| Extremal claims in the claim's own units | Inapplicable. No extremal claim is made. The finite maximum of is an ordinary finite-set bound whose existence is proved by finiteness. |
| Consequence sentences are claim surfaces | Checked independently in step 3 and in the quantifier attack. The witness proves the existential reading, with the stronger all-positive-pairs statement at that fixed base. |
| Carry the hypotheses used by a quantified argument | Checked. Finiteness of supplies its bound; and supply growth; integer supplies irrationality and disjoint classes. No boundedness of the entire parameter family is used. |
| A composition inherits its unproved premises | Checked at the exact external boundary. Only indexed dyadic completeness is imported; all strengthening steps are supplied above. The full imported proof retains its recorded acceptance and has not gained a new audit from this examination. |
| Reproducibility notes are claims | No new execution or passing-run claim is made. Reconstruction of the deduction uses the retained snapshots and exact derivations; the external replay command is explicitly not re-executed or certified here. |
| Verifier quotations are claims | No previous examination of D1 is quoted or characterized. Descriptions of the imported acceptance are confined to the supplied first Acceptance paragraph and replay record. Broader material inadvertently displayed is disclosed, not adopted as warrant. |
| Verdict words spelled in full | Satisfied in this report: the mathematical verdict is written as refutation-failed. No abbreviated verdict or self-awarded grade is used. |
| Certified brackets fail loudly | Inapplicable. No numerical bracket, enclosure routine, iteration cap or phase window occurs. |
| A harness leg without a failing input is decoration | Inapplicable. No computational mathematical leg was manufactured. The exact collision, multiplicity and deletion examples expose real failures of the candidate shortcuts. Preservation checks are not used as mathematical evidence. |
| A gate reading caches instead of rerunning is defective | No new gate or replay is claimed. Prior external acceptance is used openly under the source-premise rule; cached output is not presented as a new execution. |
The neighboring coverage discipline is met by distinguishing the symbolic deduction from the unread external proof and its unreplayed acceptance record. The correlated-sample discipline is inapplicable because there is no statistical inference. This is neither a computational batch nor a second review cycle; there is no disjoint computational reproduction obligation to discharge.
Verdict and grading
Mathematical verdict for the complete single-ray theorem and its finite-deletion strengthening: refutation-failed. Under the exact accepted external indexed dyadic theorem, the frozen argument proves eventual completeness by distinct integer values for every , , prescribed first index and finite deleted set. Its routine inference reconstructions are displayed above; no substantive missing lemma, stronger imported premise or replacement proof is used.
Mathematical verdict for the stated existential-base consequence: refutation-failed. The single base works for all positive , and therefore for the irrational-ratio pairs in the commissioned formulation. No conclusion about every real base in , the entire ambiguous catalog question, a wider classification or novelty is warranted by this report.
These are mathematical findings about the preserved subject, not a grade or a standing decision. A distinct eligible grader must assess the complete report and rule on the disclosed source-record exposure before this report is relied on as an independently accepted examination. The imported proof's full audit and a new Lean replay remain outside the report's coverage. No native tier or project-solution standing is asserted.
