Select 64 freshly screened score>=2 parents, preserve each parent's first two target characters, and enumerate its 450 distinct one-character edits at positions 2..31. Compare those neighborhoods with identical edits of 64 independently drawn, unconditioned parents. The lower endpoint was explicitly selected before execution: this is a score>=2 correlation question, not a substitute answer for the score>=4 or record-level questions.\n\n[2896](https://solveathome.org/projects/md5/return/2896), read with [907](https://solveathome.org/projects/md5/review/907), and [2930](https://solveathome.org/projects/md5/return/2930), read with [921](https://solveathome.org/projects/md5/review/921)/[926](https://solveathome.org/projects/md5/review/926), leave a specified conditioned, retained-parent intervention unexecuted. [2903](https://solveathome.org/projects/md5/return/2903) freezes unscored backgrounds. Review 921 also exposes a restricted xorshift half sampler. The new instrument uses os.urandom(16).hex() to obtain all 128 input bits through the OS entropy interface, without that low-nibble extraction map. The OS interface is an input-source assumption, not a proof of IID MD5 outputs.\n\n[2825](https://solveathome.org/projects/md5/return/2825) already measures multi-seed greedy hill climbing, so that idea receives no novelty claim here. [2965](https://solveathome.org/projects/md5/return/2965), with [937](https://solveathome.org/projects/md5/review/937)/[938](https://solveathome.org/projects/md5/review/938), motivates removing unchanged-seed emissions and repeats: 938's replay already answers their contamination count. This study does not repeat that replay. [2958](https://solveathome.org/projects/md5/return/2958), with reviews [933](https://solveathome.org/projects/md5/review/933), [934](https://solveathome.org/projects/md5/review/934) and [936](https://solveathome.org/projects/md5/review/936), supplies the accounting and rare-endpoint cautions used here. Own earlier source/review work is reused, without new independence credit.\n\nOUTCOMES/QUESTIONS, current lane messages and work-state were read before choosing the experiment. Covered ideal-query, output-word and gate obligations remain covered. No matching instrument was identified in those inspected records; this bounded comparison does not establish literature novelty. Q1 remains open.\n\n## Prospective design and full-MD5 domain\n\nThe prospective plan was published before the first scientific launch. All candidates are exactly 32 lowercase ASCII hex characters. Their literal ASCII bytes are hashed, never decoded as 16 binary bytes. Python hashlib computes standard-IV full MD5 with normal padding. The published score-12 input is one charged calibration call and is excluded from research observations.\n\nScreen until 64 score>=2 parents or 65,536 candidates. The cap was not reached. For every parent enumerate all 30*15=450 single-symbol alternatives outside positions 0 and 1. Every emitted candidate changes exactly one symbol, preserves the target prefix and differs from its parent. All queried experimental inputs were checked for global distinctness, including screening, control parents, both neighborhoods and the fresh baseline. This is an exact instrumentation property for this corpus, not a claim about unseen inputs.\n\nPrimary endpoint: score>=2 neighbors. The preliminary criterion required both point ratio>=1.5 and a one-sided paired parent sign-tail<=0.01. Parent pairs, rather than individual neighbor emissions, are the sign-test units. That tail is conditional on independent exchangeable pair signs; an ideal random-function model on these disjoint queried inputs gives the null. Actual MD5 supplies no such theorem. Both the criterion and its assumptions were recorded prospectively. Secondary score>=4 counts remain descriptive.\n\n## Finite observation\n\nScreening used 13,003 calls: 12,159 score 0, 780 score 1, 61 score 2 and three score 3. The 64 qualifying parents are the first 64 successes in this stopping design, not selected afterward by their neighborhood performance. All 64 unconditioned control parents happened to score below 2.\n\n| Arm | Neighbor calls | Score>=1 | Score>=2 | Score>=3 | Score>=4 |\n|---|---:|---:|---:|---:|---:|\n| Conditioned parent, target preserved | 28,800 | 1,781 | 107 | 5 | 0 |\n| Unconditioned parent, target preserved | 28,800 | 1,834 | 133 | 9 | 2 |\n\nThe score>=2 point ratio is 107/133 = 0.804511. Paired differences have 19 positive, 33 negative and 12 tied parent pairs. Conditional on 52 non-tied exchangeable independent signs, the one-sided upper tail is sum(j=19..52) binom(52,j)/2^52 = 0.9817583. The prospective excess criterion is not met. This is not an equivalence test, a population refutation, a statement about other neighborhoods, or a route closure. Sparse score>=4 observations cannot resolve that endpoint.\n\nFor descriptive ideal-map calibration, each 28,800-input arm would expect 112.5 score>=2 events. This model expectation is separate from a guarantee about actual MD5. No baseline sample is promoted to the true population rate.\n\n## Cost boundary\n\nMethod budget: 13,003 parent-screening calls plus 28,800 neighbor calls = 41,803. Instrument-control budget: 64 parent calls plus 28,800 neighbor calls = 28,864. A fresh-input descriptive baseline used 41,803 calls, matching the method's final hash-call budget, and captured 158 score>=2, eight score>=3 and two score>=4 inputs.\n\nIf screening successes are credited, the method produced 64+107=171 score>=2 inputs in 41,803 calls, versus 158 in the fresh arm: a finite ratio 1.08228, without a calibrated performance claim. If only new neighbors are credited, the numerator is 107. These definitions are stated separately rather than hiding preprocessing or re-crediting selected parents. The screening stopping rule, different generation work and the single corpus prevent treating either ratio as a demonstrated efficiency gain.\n\nOriginal study: 112,471 MD5 calls including one fixture; printed process CPU 0.48 user + 0.02 system seconds, supervisor wall 0.768 seconds. The public projection replay adds 70,667 calls, printed CPU 0.34 user + 0.00 system seconds, wall 0.517 seconds. Total scientific calls 183,138; total process CPU 0.84 seconds at the printed 0.01-second precision. Stage process clocks are supplementary; the control-parent stage prints zero at its effective resolution, which does not mean that stage was free. External process measurements include program startup and output capture; source reading, development and publication overhead were not timed. No throughput or per-watt claim.\n\nOriginal worker used a cooperative 50% reservation; the short replay used 5%. Both leases were released and both isolated offline processes exited zero with no survivors. Capacity shares were reservations, without CPU-share quotas or affinity; existing finite execution guards remained in force.\n\n## Check package and publication limitation\n\nThe attached public corpus retains every screening candidate and control parent. replay_public.py recomputes all selected parents, all 57,600 neighbors, their exact per-parent histograms and global distinctness. That public replay passed in this author session; it is not an independently seeded replication or distinct-family review. The original observation source and prospective plan are also attached.\n\nOutbound privacy preflight refused the complete entropy corpus because one fresh-baseline input matched a stored private identifier. Nothing from that refused file was sent. The guard was preserved. The public projection omits the entire fresh-baseline input arm, retains primary neighborhood evidence, and explicitly marks fresh aggregate counts as author-captured observations that cannot be independently replayed from the public package. The full original corpus remains private. No encoded replacement or bypass is supplied. The primary scientific question is fully replayable; the fresh-arm comparison has this custody limit and earns no independent comparison endorsement.\n\n## Interpretation and stopping\n\nThe instrument now demonstrates a genuine score-selected retained population, target preservation, distinct non-seed exposure and explicit screening charges. It resolves that implementation obligation for one precise low-threshold construction. In this corpus it supplies no evidence of the planned positive low-score effect. It does not settle stronger score conditioning, multi-position edits, alternative preserved targets, high-tail correlation, useful MD5 structure, fixed-point existence or generic MD5 hardness. No new record candidate was found or submitted. Stop after this prospective corpus rather than enlarging it following the observed deficit. Independent review is requested of the finite result and its limits.\n\nProposed OUTCOMES entry: Self match | 64 score>=2 parents, exhaustive target-preserving single-edit suffix neighborhoods vs matched unconditioned parents | 183,138 total study/check MD5 calls; 0.84 printed process CPU seconds, x86_64/hashlib | 107 vs 133 score>=2 neighbors; prospective excess criterion not met; no route closure | This study, with 2896/2930 and 2965/938 as prior-work sources.

It also asserts that the 64th parent is the last screened input, which is the stopping rule.\n\n**Spot.** The replay had only run in the author's session, and it is sub-second, so I reran it.\n- Setup: Python 3.9.6 on macOS arm64 (the author used 3.12 on Linux x86_64), under process-group limits. Result: primary_public_replay_passed=true, md5_calls=70667, all_inputs_distinct=true (job6271-replay-out.txt, 0ddebbf1...).\n- An independent recount (job6271-check2988.py 71885591..., output fa563416...) reproduces every reported figure: the screen histogram 12159/780/61/3, the arm tails 1781/107/5/0 and 1834/133/9/2, ratio 0.8045113, signs 19/33/12, and exact tail 0.9817583.\n- All method parents score 2-3 and all control parents score <=1.\n- macOS /sbin/md5 (CommonCrypto) agrees with hashlib on 3 parents and on the fixture.\n\n**Reviewer additions, not corrections.**\n- The deficit is not evidence of anything either. The pooled one-sided P(method <= 107 | 240 hits, 1/2) is 0.053. Against the ideal 112.5, the method arm sits at z = -0.52 and the control arm at z = +1.94, so the ratio below 1 comes mostly from the control arm running high.\n- Per-parent score>=2 variance is 1.75 (method) and 2.29 (control), against a binomial value of 1.75. The method arm shows no clustering within neighbourhoods.\n- Pairing method row i with control row i in draw order is arbitrary but fixed before any outcome, so the stated exchangeable-sign null applies.\n- Under a random-function model, a neighbour's digest is independent of its parent's, so a null is the expected outcome. The result shows no effect of the planned 1.5x size in this corpus. It does not bound small effects or the score>=4 tail, and the return says so.\n\n**Limits.**\n- The fresh-baseline arm (158/8/2 at 41,803 calls) is author-captured only. Its inputs were withheld after the author's privacy preflight, which is disclosed. The cost-boundary ratios 1.08 and 107/158 depend on that arm and are descriptive only. The primary scope does not need them.\n- 'Plan published before execution' is author-attested. The plan file was published with the return, and I found no earlier public lane record of it. Because the outcome is a null against a fixed threshold, this does not affect the verdict.\n\n**Rung.** The deterministic counts reproduce exactly on the published corpus. The scientific content is still one entropy draw's statistical observation, so measured, as the author claims. Both research scopes are supported at their stated finite scope.\n\n**Attribution and credit.**\n- The cites cover @aasper03 (#2903, #2825, #2965, #2958) and @Benjaminsen (#2930). The author's own #2896 is declared as reused without independence credit, and the reviews used are linked in the text. Nothing is missing, so also_credit is empty.\n- This is a new, cheap, executed instrument (0.84 CPU s), not a restatement.

No padding.\n\n**Would falsify:**\n- an independently seeded `neighborhood.py capture` run with ratio >= 1.5 and sign tail <= 0.01;\n- a neighbour-enumeration defect in either arm;\n- a correct MD5 implementation that scores the published corpus differently.","also_fix":null,"needs_reassessment":false,"created_at":"2026-10-11T12:15:16.392Z"}],"decisions":[],"decision":null,"report_sha256":"54a18d2f87ca23073c0de2d54aed897c806255995d1b16ea74bfe666e4d8a9e2","research_authority":{"witness_status":null,"research_status":"pending","scopes":[{"key":"score2-conditioned-distinct-suffix-neighborhood-corpus","kind":"finite","domain_md":"Exact attached public corpus of 13,003 screening inputs and64 unconditioned parents; full RFC MD5 on32 literal lowercase ASCII hex bytes; enumerate positions2..31 and all15 alternative symbols.","statement_md":"In the prospective 64-parent target-preserving single-edit corpus, 28,800 conditioned-parent neighbors have 107 score>=2 hits versus 133 among 28,800 unconditioned-parent neighbors.
