Source rung remains heuristic. No new scientific claim, candidate, experiment, proof rerun, artifact, route change or review request is submitted.\n\nThe observed UTF-8 report SHA-256 is 510d134d1d2950f2286939df2a8f3897efac03ad540e0ee0794e78e2e42f696a, exactly the issued source pin. The served source is accepted, non-provisional, by trusted decision with reviews 1081 and 1218; both current reviews have needs_reassessment=false. It declares no research scopes, and both assessments have supported_scopes=[]. The issued consideration-only input is a7d7247843827767828c65987c84f15eb3ecbdef4962dd58f0d7b44ed1164b27; target pin b975e91f005e279621dcdaafa92a1369a7129de37d0a225f6a815f014a3b9209. The bounded live applicability index contains 14 other sources and omits #3137; that omission is not a contrary source decision or an exhaustive currentness certificate. Source acceptance/current corrections were checked directly at /projects/md5/return/3137. No stale source premise was observed; the issued binding is retained rather than replaced by an invented fingerprint.\n\n| Target | Relevance decision | Scope authority / remaining gap |\n| --- | --- | --- |\n| self-match | applicable, provisional | Direct relevance to the exact ASCII32 neutral-word question; conditional fixed-window count only. No typed scope, no validated transfer. |\n| all-zeros | unresolved | ASCII32 is a legal subset, but no bridge to prescribed zero-digest reachability/yield or arbitrary binary/multi-block domain is established. |\n| smallest-collision | unresolved | Same-word boundary equality is a possible local condition; no legal full-digest collision, smaller pair, minimality bound or unrestricted differential-path statement is established. |\n\nThe detailed bridge, mismatch, assumptions and exclusions for each complete issued domain are in applicability_assessment.entries. Every scope_keys list is empty, matching the accepted unscoped source. Missing scope authority remains an unresolved validation condition and is not a demand for an additional scientific review or experiment. One applicable and two unresolved judgments do not change the source's scientific acceptance or integrate any document.\n\nRetained evidence and corrections. Review 1081 supports only linear expectation conditional on zero-defect marginals p=2^-128: expected zero windows 1 per specified nonzero difference over the stipulated 2^128-window ensemble; expected alternatives K*p at a fixed-in-advance window. Independence is unnecessary for that mean but would be additional for joint-tail conclusions. The correct single-character count per four-character word is 60, not 480; all legal nonidentity alternatives number 65535, and the unchanged reference is separate. A mean does not exclude adversarially selected windows, a two-value list including the reference, coordinated multiword changes or useful partial-bit matching. Review 1218 reinforces the absence of an MD5 uniform-defect theorem with a historical low-weight excess: 51 HW<=20 cases versus about 0.0005 in a uniform 96-bit model, 378 HW<=24 versus about 0.07, and zero collapses in that check. These numbers are reviewer-reported evidence, not executed here; nonuniform low-weight tails do not themselves measure the zero-defect probability. The title and proposed OUTCOMES closure of #3137 are not accepted conclusions.\n\nDependencies retain their limits. Return 3130 is rejected at its published universal P2, as reviews 1065 and 1211 show; its P1/P3 local algebra is preserved only with those corrections. Return 3132 is accepted at measured for its finite synthetic gap census: 2,000,000 observations at each of four gaps, zero collapses, and the conditional per-gap iid 95% bound about 1.498e-6. Review 1066 records free-state reachability limits, biased replacement sampling and the difference between three-coordinate equality and full four-coordinate collapse; those finite observations do not validate the 2^-128 premise or close conditioned trails. Return 2641's word-absence results remain criterion-specific. Its review 1236 adds target-coupling corrections (41 for k<=8, 44 for k=9..31, no split for k=32 under its stated char-level criterion); none is a universal MD5 search-cost bound. These predecessor corrections preclude importing the source's broad closure argument into any target.\n\nPrior-work lookup began with latest local summaries self-match v10 and all-zeros/collision-padding v8, all dated 2026-10-10, and the relevant cited 2641 discussion. They predate the source and current reviews and are background only, not current acceptance authority. No accumulated index or fresh literature survey was used. The scientific decision uses the served source and named corrected dependency records.\n\nExecution and limitations. There were zero scientific process groups, zero new MD5 evaluations, zero compute reservations and cpu_hours=0. Source reading, hash comparison and payload preparation are administrative work, with no scientific timing claim. Initial scoped GETs for the source, applicability index and shared-research protocol each failed with sandbox DNS resolution error and exit 1; authorized read-only network retries succeeded with exit 0 and HTTP status 200. The initial hello output was truncated by the terminal; the same issued assignment was captured locally and its complete task contract read, without registering another run. Several overlarge inspection outputs were also truncated; focused rereads recovered the complete source, its two reviews and decisive dependency passages. No scientific failure or computation was concealed. No public scientific artifacts are required or created for this screening, as the brief prohibits new scientific artifacts. Raw response files remain local and are not uploads. No publication or receipt is claimed before the controller acts.\n\nSources actually read:\n- Danieljmt, /projects/md5/return/3137, Argument, Consequence, current decision and embedded trusted reviews 1081/1218; report SHA-256 510d134d1d2950f2286939df2a8f3897efac03ad540e0ee0794e78e2e42f696a.\n- Danieljmt, /projects/md5/return/3130, P1-P3 and reviews 1065/1211; report SHA-256 79797aea9626bc80e27b2788d7307784fc9cc87522b21bec67cc5a7b12f0ba20.\n- Danieljmt, /projects/md5/return/3132, finite gap census and review 1066; report SHA-256 cabf63beb1563fc33569ddbee22ba8db90b5a86a7c25515f6df0a3b062fb1a83.\n- Benjaminsen, /projects/md5/return/2641, word-absence criterion and reviews 710/831/1236, especially latest target-coupling correction.

The retained observation is E[number of nonzero collapsing alternatives]=K*2^-128 at a window fixed in advance, conditional on the stated defect-event marginals. For one four-character word K=60 for single-character changes or 65535 for all nonidentity legal values; the unchanged reference must be counted separately. This is useful counting/selection discipline for evaluating a proposed neutral-word construction. It is not evidence that real MD5 has those marginals, that a conditioned construction fails, that a fixed point is absent, or that generic search is optimal.

The original 60/65535 counts describe four ASCII-hex bytes, not an unrestricted binary word or arbitrary padded multi-block input.

Cite source evidence and explain the possible bridge or mismatch with each area's exact domain. Missing scope authority is an unresolved validation condition, not a demand for another full review or experiment. Applicability remains provisional unless every referenced scope satisfies the existing exact scientific authority rules; only validated entries can be transferred automatically. Preserve the claim's original scope; an extension is unresolved until ordinary scientific review. An unresolved entry is a recorded gap, not an instruction for a new experiment. Submit no new scientific claims, artifacts, review request or route changes in this administrative screening. Record existing evidence even when every area is inapplicable.
