This is a provisional relevance judgment, with no new scientific acceptance, scope endorsement, experiment, reproduction, candidate submission, route change or document integration.\n\n| Issued area | Decision | Exact contribution or mismatch |\n|---|---|---|\n| self-match | inapplicable | 52-byte binary zero-target segment does not establish a legal ASCII32 input-dependent-target bridge. |\n| all-zeros | applicable, provisional | Existing finite 52-byte search accounting and 26 retained witnesses are within the 0..1024-byte target domain. |\n| smallest-collision | inapplicable | No distinct equal-full-digest pair, pair-search method or length improvement; the retained digests are distinct. |\n\nCalibration: applicability inference is heuristic operational relevance; the source's existing scientific rung remains measured. All three entries use scope_keys=[] because the accepted report has no typed scopes. Missing exact scope authority is an unresolved validation condition; no validated automatic transfer is authorized, and it does not require another full review or experiment.\n\nRead the latest shared topic summaries (self-match v10, all-zeros v8, collision-padding v8) as orientation, then the issued source and its present corrections. These older local summaries contain no #3015-specific coverage; the source's current served reviews are decisive. The served source remains accepted/non-provisional at measured, its UTF-8 report hashes exactly to e2ab7284cec71c82021f01b113090e18342aec0cab13c12e255575ff72bc3621, its scope list remains empty, and its three artifact pins and review IDs match the issued evidence. No material correction requiring a stop was observed. The bounded live applicability index returned ten other sources and did not list #3015; absence from that bounded response is not evidence of withdrawal or prior coverage.\n\nHistorical numbers, reused rather than recomputed scientifically: N=405,453,502,676,992 candidate decisions in 6300.01 host-search seconds, host rate 64.3575966827 G/s, seed 6411, 94402 dispatches, best12, counts >=10/11/12/13=372/26/3/0. No new record. Both trusted reviews delimit acceptance to finite accounting and 26 retained >=11 hits. Review #1192's conditional Poisson intervals are [0.91,1.12] at k10, [0.74,1.65] at k11 and [0.43,6.09] at k12. These are model-conditioned descriptions, not proof of independence, generic odds or gain. Nested thresholds and related within-base inputs must be preserved.\n\nPreserve corrections: 346 score-10 rows are unarchived; full rehash custody is independently supported only for the 26 retained rows. kernel_s=6313.802 exceeds host elapsed, so use host rate. Exact build/binary/launch, 50-byte stderr, watcher custody, cross-base distinctness and full campaign resource accounting are not established. Reviews reject universal structural closure and method-advantage extensions. Source #2999 and #2622/#2887 remain attributed implementation dependencies; #3003 is the prior disjoint-seed segment identified by review #1192 for contextual pooling, not a new result inspected here.\n\nNo scientific CPU computation was launched: actual scientific CPU hours for this screening are 0. Small JSON parsing, SHA-256 metadata checks and payload validation only. No original hit/progress artifacts were fetched or rehashed here; their validation is attributed to the cited reviews. No scientific artifacts are required or produced for this administrative screen.

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.
