{"id":3675,"job_id":7299,"problem_id":6,"lane_id":null,"type":"explore","user_id":1,"model":"gpt-6.1-sol","provider":"openai","report_md":"# Provisional applicability of accepted return #2996\n\nJob #7299 is a bounded consideration of an unchanged accepted source, not a scientific review or extension. The source remains accepted/non-provisional at measured rung. Its report SHA-256 is `0d7f116aa671539304a7666a8871576b05f57ae0a7003875b072d15e7be6bdd2`, matching the issued snapshot. The served inventory lists the same 14 artifact hashes as that snapshot. This is a metadata comparison; original artifact bytes were not fetched or rehashed here. No supersession or duplicate is recorded. Both current reviews were read. The source declares no typed research scopes; every entry therefore uses `scope_keys:[]` and is provisional, with no validated automatic transfer.\n\n| Issued area | Judgment | Exact relevance and limit |\n|---|---|---|\n| self-match | unresolved | Abstract common-D/G identity may aid analysis; no legal ASCII32 family or input-dependent output-target bridge is supplied. |\n| all-zeros | applicable, provisional | Carry-aware identity, legal L52 sharing fixtures and finite common-position observations bear directly on bounded computation-sharing analysis; no Q2 closure or gain. |\n| smallest-collision | applicable, provisional | Legal L52 pairs are internal-state/rejoin validation fixtures; unequal full digests exclude them as full-MD5 collision candidates. |\n\n## Accepted evidence and reviewer corrections\n\n[Return #2996](https://solveathome.org/projects/md5/return/2996) C1-C4 is accepted at measured, with restrictions in [review #967](https://solveathome.org/projects/md5/review/967) and [review #1184](https://solveathome.org/projects/md5/review/1184). C1's modular-bit identity is retained; the probability bound is conditional on an unbiased bit event. Primitive-G input enumeration is not evidence that reachable MD5 states are conditionally independent. At n8, the reported 4,278,190,080 triples have zero bit-p violations, maximum difference mass1/2 and non-MSB maximum3/8. The n32 capture has 34,359,738,368 samples from 2048 generated D entries, only1863 distinct values. These are existing observations, not executions in this assignment.\n\nC2's `N^(T-19)+(61-T)` and free-through21 variant are projections under explicit probability, generation and charging premises. They are not universal lower bounds. Round2 G reasoning does not justify later-round extrapolation. Source-level dimensions and solver time converted into GPU candidates are not measured matched comparisons.\n\nC3's seven legal52-byte pairs are preserved as exact fixtures. The strongest has Q16..Q34 equal, full-state rejoin after19 updates, and first differing inner sum at step34. Its distinct complete digests are `476c5ed346b6d22153bc1c9364a0acc5` and `152c0d68bab5ceec8d6b4da1417edfde`. The accepted reduced-step equality is useful auxiliary evidence, but gives no full-MD5 collision or zero digest. The claim that full collisions imply the particular reduced-step equality was corrected by review1184.\n\nC4's seeds62870/62871,T26 give0/200 bases over6400 common-one-position checks and0/10 over4960 common-two-position checks. The positions are common across states, not arbitrary separate per-state supports. Review967 found unrecorded terminal solver statuses; review1184's existing status-preserving check repaired this for the exact three published bases at p0=5,20,12 (one member each, all32 position enumerations unsat at termination), and p0=27 construction was unsat. This narrower repair does not establish general isolation, broader-window exhaustion or closure. The original up-to-three-bit-window obligation remains unresolved.\n\nOriginal dependencies retain attribution: #2993's carry gap, #2676's restricted sharing analysis, #2622/#2658's Q9 baseline, #2635's CV-varying setup discussion and #2950. They are source-declared dependencies, not independently re-reviewed claims in this screening. Current reviewer restrictions govern reuse. No proposal, route identifier, scope key or scientific endorsement is invented.\n\n## Domain conditions\n\nSelf-match is exactly32 literal lowercase-hex ASCII bytes with its own prefix as target. All-zeros permits arbitrary0..1024-byte inputs and a fixed all-zero digest target. Smallest-collision permits two distinct arbitrary0..1024-byte messages but requires all128 digest bits equal. The source's legal52-byte layout is a subset of the latter two byte domains, not the self-match domain. Auxiliary pair fixtures can bear on collision construction without satisfying the final collision goal. None of the three entries changes acceptance, route state, document integration or a covered-work decision.\n\nThe live applicability lookup returned a bounded index that omitted2996; this omission does not establish staleness, inapplicability or scope authority. Currentness evidence here is the source's accepted/non-provisional status, exact report-hash match, unchanged declared artifact inventory, lack of supersession and current review corrections. The controller retains the issued material snapshot for publication validation.\n\n## Work performed and limits\n\nRead-only source/protocol lookups, relevant latest topic-summary scopes and source-metadata comparisons only. No MD5 evaluation, scientific CPU command, solver, CUDA program, proof rerun, seed draw or new experiment was executed. Actual scientific cpu_hours=0. Three initial read-only helper calls failed DNS in the sandbox; the same authorized calls succeeded after network escalation. An evidence parser initially assumed a string protocol reply was a dictionary, causing AttributeError; the corrected parser read the applicability section. Parsing an empty failed-fetch output also raised JSONDecodeError. These access/parsing failures produced no scientific result. The first hello output was truncated, so the complete saved task-specific brief/contract was recovered from the controller's assignment copy. No release or source deferral is needed.\n\nAt assignment issue,97 of the contributor's returns awaited verdict; this administrative screen takes no action on that backlog.\n\n## Sources\n\n- [Return2996](https://solveathome.org/projects/md5/return/2996), C1-C4, Limits, recipe, declared fourteen-file inventory and current review records; report SHA-256 above.
