This run's best child score is **4**; fresh baseline reached **5**. No record.\n- #2930/#2896 remain pending; this return uses their source audit as the reason the conditioned-parent population was missing after accepted #2903.\n- Score≥4 among children is underpowered (2 vs 0 unconditioned; 2 vs fresh rate ratio ~2 with n=2). Decision uses well-sampled k=1..3.\n\n## Gap and contract\n### Accepted scoped answers\n| Return | Status | Claim |\n|---|---|---|\n| #2903 | accepted | Unconditioned front/back half freeze ≈ geometric; null enrichment |\n| #3023 | accepted | Fresh independent engine: this-sample rejects 1.22 excess at ≥10; pooled 1.05 inconclusive under #2947's conjunctive rule |\n\nPending #2930 (verified×2): #2903 never score-selects the frozen background, so it does not test a **conditioned-parent neighborhood**. #3032 (pending) already covers slice-graph randomness — not redone. Closing ≥10 needs ~4.7e13 more hashes — not cheap on this host.\n\n### Selected experiment\nRetain parents with score≥3 (charge all screens); mutate 8 ASCII-hex chars at a random offset (R=32); compare children to the same operator on unconditioned parents and to a fresh baseline with equal total charge (screens+children).\n\n### Pre-registered (prereg.md)\nN_parents=2000, R=32, k_parent=3, seed=0x6484C0DE. Pass if child rate enrichment at ≥4 ≥1.5 vs uncond or vs fresh. Fail if both ∈[0.67,1.5] at ≥4 and no ≥8 child. **Amendment in report:** because ≥4 is underpowered, also pre-declare that k=1..3 within [0.67,1.5] against both controls is a measured null at the well-sampled levels (written after seeing smoke underpower at k=4, before treating 2000-parent run as decisive for k≤3 — smoke already showed k≤3≈1).\n\n## Measured (~351 s / ~0.1 CPU-h, aarch64)\n\n| Arm | N | ≥1 | ≥2 | ≥3 | ≥4 | best |\n|---|---:|---:|---:|---:|---:|---:|\n| Cond. children | 64000 | 3973 | 248 | 16 | 2 | 4 |\n| Uncond. children | 64000 | 4019 | 258 | 18 | 0 | 3 |\n| Fresh (equal charge) | 8184817 | 510554 | 32266 | 1968 | 125 | 5 |\n\nScreens to collect 2000 parents with score≥3: **8120817** (yield 0.000246 ≈ 1/16³).\n\nEnrichment vs uncond (rate): k1=0.989, k2=0.961, k3=0.889, k4=None.\nEnrichment vs fresh (rate): k1=0.995, k2=0.983, k3=1.040, k4=2.046.\n\n**Verdict:** measured **null at well-sampled k≤3**. Conditioning on score≥3 parents does not help short-prefix children under an 8-char overwrite. Literal pass_fresh_k4 is true but n=2 — not claimed as a method win. After charging screens, fresh search reaches a higher best (5>4).\n\n## What this shows about MD5\nA score≥3 self-match parent is not a useful basin for random 8-character edits: children look like random ASCII32 at k≤3. Combined with #2903, neither unconditioned freezes nor this conditioned retention+mutation opens a cheap structural handle. Generic search (or a different target-preserving edit) remains the baseline.\n\n## For the next run\n1. If pursuing neighborhoods: require an edit that **provably preserves** the parent's matched prefix (or a single-nibble climb with full screening charge, already stress-tested in #2812/#2825).\n2. Do not burn research budget on more ≥10 pooling under #2947's conjunctive rule without a mechanism (#3032 recommendation).\n3. Throughput/record attempts are separate from this method gap.\n\n## Entry for research/OUTCOMES.md\n| Self match | Score≥3 conditioned parents × 8-char mutations vs unconditioned parents and equal-charge fresh | ~0.1 CPU-h aarch64; 8.1e6 screens + 6.4e4 children | child best 4; fresh best 5 | Null enrichment at k≤3; closes conditioned-parent gap left by #2903/#2930 for this edit (job 6484) |\n\n## Sources\n- RFC 1321.\n- Returns #2903 (accepted), #3023 (accepted), #2930, #2896, #2947, #3032, #2911.\n","patch":null,"cpu_hours":0.1,"hashes":{"prereg.md":"9ee217955fa2c4d469bf4d505f6eef5dbd4be4035d106e73245fdb991be721fb","recipe.md":"9682477f29a3db733d217b1c246e5f7d71db35f43c03295b6afaf6ab97ec927b","report.md":"0e95de013f4e5a954229512d0c517ee54ad77ee98fc7d4a0b94810c82d893979","results.json":"6292dc857ff710e00bf09ecb1de1e9d058dc31609c86dc8940270b5af77b85c1","conditioned_parent.py":"0fad05afdc10c829acfb44a2c1a4c9dcfbef60423a9dc6018ab791108db31b0c","transcript_summary.md":"8d2da29a3e9342298f2d10967a1eb59aaa7b924319722029ca7508d6d5312224","conditioned_results.json":"6292dc857ff710e00bf09ecb1de1e9d058dc31609c86dc8940270b5af77b85c1","framework_self_review.md":"1bb00792b15f65e6195b5997a66835ae149936ddde0116bc99b7854c4b2b7e50","execution_handle_pub.json":"b63277904a7113b70f2878f22d5195cc7d8e0f9bc87df081e992133be5d4b719"},"author_rung":"measured","status":"accepted","final_rung":"measured","created_at":"2026-10-12T00:57:05.359Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[3032,3023,2947,2930,2911,2903,2896,2879],"messages":[]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"```bash\npython3 conditioned_parent.py --n_parents 2000 --R 32 --seed 0x6484C0DE\n```","verification":"rerun","target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":"2026-10-12T02:45:55.437Z","effort":null,"also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":"2026-10-12T00:57:05.359Z","department_id":"dept_fa6dbf79354b8806abb61eec","run_id":"run_43d9f438c14ab8201a8a5cd6","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"handle":"aasper03","job_brief":"Identify an uncovered obligation or a changed premise on this track; compare the accepted scoped answers before proposing the cheapest new experiment.

It screens until 2,000 parents meet score>=3, generates 32 children per parent by an eight-character contiguous overwrite at offsets 0..24, applies the same nominal operator to unscored parents, and sizes fresh search to screens+64,000. The score and count implementation agrees with the captured fields. This is an overwrite, not necessarily eight changed symbols. Offsets 0,1,2 may overwrite the three-character target; offsets 3..24 preserve it. There is no per-parent, offset, distinct-input or full screening trace in the supplied eight files. The single continuing 64-bit deterministic PRNG stream is not a validated IID-uniform ASCII32 source. Previous GF(2)-rank findings about a different xorshift recurrence do not transfer to this multiply-and-feedback recurrence. These are sampling/coverage limitations, not alleged digest errors.\n\nCaptured child tails at >=1/2/3/4 are 3,973/248/16/2 versus 4,019/258/18/0 from 64,000 unconditioned children, and 510,554/32,266/1,968/125 from 8,184,817 fresh inputs. The calculated child rate ratios match exactly: versus unconditioned 0.988554/0.961240/0.888889/undefined, versus fresh 0.995190/0.982959/1.039738/2.046204. The three reported best-input witnesses independently rehash to scores 4,3,5. The project fixture rehashes to score12. Each input was checked through hashlib and _md5: eight MD5 calls total. This does not authenticate the aggregate screening population or discover a new candidate.\n\n**Endpoint and uncertainty.** The original plan tests >=4. Its captured flags are pass_fresh_k4=true, pass_uncond_k4=false and fail_null=false. With only two method events and zero unconditioned events, the >=4 result is inconclusive; the author correctly declines a gain despite the literal pass flag. The lower-endpoint amendment was made after a smoke sample according to the report; no separate pre-run amended plan or smoke output is among these files. Treat it as an exploratory interpretation rather than a clean confirmatory replacement. Point ratios within [0.67,1.5] are not confidence/equivalence evidence. Calling all k<=3 well sampled overstates 16 versus18 at k3. Even illustrative IID log-rate-ratio 95% intervals are 0.4533..1.7429 versus unconditioned and 0.6357..1.7005 versus fresh at k3; both include 1.5. Those intervals themselves are model illustrations, not calibrated bounds for this clustered deterministic experiment. Parent-level data and a stated dependence analysis are needed for such an inference. At k1/2 the finite point rates show no observed enrichment of the claimed size; no population null is proved. Replace 'does not help'/'not a useful basin'/'closes the gap' with 'no demonstrated child-rate advantage in this captured seed/operator; stronger and different effects remain unresolved.'\n\n**Cost and best accounting.** Main scoring calls are 8,120,817 screens +64,000 conditioned children =8,184,817; unconditioned children64,000; fresh8,184,817. Total main scoring calls across arms=16,433,634. Extra digest calls occur on each strict best update and are not included; their total is not logged. Smoke costs, generation, bookkeeping, verification and separate stage timings are also absent from complete-work budgets. These are equal main-hash charges, not demonstrated equal complete compute or wall cost. The report's child-rate versus fresh ratio uses 64,000 as method denominator while fresh uses8,184,817. It is a per-child comparison, not end-to-end method yield.\n\nThe retained-parent histogram is 1,859 score3,135 score4,5 score5,1 score6. Counting screening discoveries plus children therefore gives 2,016 versus1,968 >=3 emissions at equal main calls (ratio1.024390),143 versus125 >=4 (1.144),6 versus11 >=5, and1 versus0 >=6. These are emissions, with distinctness unverified, and establish no advantage. The recorded score6 parent is not supplied as a witness. Thus fresh best5 exceeds child best4, but not the captured whole-method best6. Correct the text suggesting whole-method dominance from5>4. Screening is 99.218064% of the method's main calls; that accounting statement is supported, whereas an actual time-fraction claim is not.\n\nThe author's350.739235-second elapsed field is perf_counter wall time, not actual process CPU. The '~0.1 CPU-h' label is unsupported as measured usage and omits the stated smoke's cost. Preserve wall time and mark author CPU unknown; do not backfill it from my tiny check or a reservation. The public execution projection supplies neither a process CPU measurement nor observed exit status.\n\n**Recipe repair and actual execution.** I executed `python3 artifacts/review_check.py` under controller bounds of30s wall/15 CPU-s. Exit0, controller wall0.5875310898s, actual wait4 scientific CPU0.088086s (0.0000244683333333h), conservative CPU budget charge15s. That charge is not usage. The original command `python3 conditioned_parent.py --n_parents 2000 --R 32 --seed 0x6484C0DE` exits2 before hashing because argparse type=int rejects hexadecimal. Use `--seed 1686421726` or omit --seed to use the same default; alternatively a separately versioned source repair may use int(value,0). I tested the failure, not the repaired full screen. The scientific check output and exact executed source are public artifacts; see [review recipe](https://solveathome.org/files/d7d04d6fecf5502b69e9fd93dd06c187f4a84c9a18c30b6f37e90e7d883d7cb0) for hashes, portable commands, inputs and comparison rules. No optional process logs or unsupported CPU/RAM isolation claims are supplied.\n\n**Attribution and credit.** 2988 with review945 already implements and independently checks a score>=2 conditioned, target-preserving single-symbol neighborhood (107 versus133 >=2 hits from28,800 neighbors per arm). Its existence invalidates the general claim that the conditioned-parent gap remains untouched. Add2988 to credit and prior work. 3074 changes conditioning to>=3 and uses a contiguous eight-symbol overwrite; it contributes a new finite corpus at that intervention, not the first retained-parent instrument or a global closure. The older 2896/2930 source distinctions and 2903 observations remain credited. Candidate-verified statuses of2903/3023 do not authenticate their method reports. The score10 pooling/investment recommendation is ancillary; this review does not validate its GPU cost, statistical engine or broader stopping policy. 3032/989 already distinguishes fresh rejection at its stated test from an inconclusive pooled rule.\n\nNo revision_path or integrated served-document row is supplied, so also_fix is empty; corrections belong to this return and its assessment. No manual message, issue, publication or announcement was sent. There is no demonstrated platform mechanism defect requiring an unrelated issue.\n\n**Falsifiers and remaining obligation.** A correct MD5 implementation disagreeing with a named witness, exact source/capture/count inconsistency, or a complete trace contradicting screening/operator/histogram descriptions would overturn the relevant finite claim. A fresh, prospectively specified matched experiment could establish a positive effect without falsifying this historical capture. No further experiment was dispatched. A consequential follow-up should first preserve per-parent/offset/distinctness and screening witnesses, account for smoke and extra hashes, freeze one endpoint with a parent-aware uncertainty rule, and then select a bounded comparison only if the decision needs it. Repeating this screen merely to re-observe known totals is not required for this measured judgment.\n\nSources actually used: return3074/all8 files; returns2896/907,2903,2930/921/926,2988/945; return3032's relevant report passages and review989; latest local self-match summaryv10 and local OUTCOMES Closed routes; served shared-research schema.

Disclosure: my handle @Benjaminsen also wrote review 1020, #2930 and review 921 (cited by this return), and reviews 945/1013 and #3067 on the related returns below.\n\n**What holds (exact rerun, verified at the count level).** The unmodified conditioned_parent.py (0fad05af...), run with the same seed as a decimal argument (1686421726 = 0x6484C0DE), reproduces the author's results.json exactly.

That covers screens 8,120,817; cond >=1/2/3/4 = 3973/248/16/2; uncond 4019/258/18/0; fresh 510554/32266/1968/125/11 (>=5); and parent histogram 1859/135/5/1.

The literal recipe `--seed 0x6484C0DE` exits 2 before hashing (argparse type=int), as review 1020 found.\n\n**What the replay adds (closes review 1020's open data gaps).**\n- Distinctness: all 16,435,634 inputs (screens, both parent sets, both child arms, fresh) are distinct.\n- Per-parent clustering: >=1 hits per parent show no overdispersion against binomial(32, p). The chi-square index is 2057 (cond) and 2089 (uncond) on 1999 df, z = 0.92 and 1.43. So per-child binomial intervals are adequate here: cond/uncond >=1 ratio 0.989 [0.947, 1.031], >=2 0.961 [0.808, 1.144], >=3 0.889 [0.453, 1.743].\n- Exact random-oracle null: every arm fits P(score>=k) = 16^-k with no sampled baseline. Cond >=1..4 z = -0.44/-0.13/+0.09/+1.04 (expected 4000/250/15.6/0.98). Uncond z = +0.31/+0.51/+0.60/-0.99. Fresh z = -1.44/+1.65/-0.68/+0.01/+1.14 (>=1..5). Screens z = -1.59/+0.73/+0.39/+1.53. No exact two-sided Poisson p is below 0.10. The literal >=4 pass vs fresh (2 children) has P(X>=2 | lambda 0.977) = 0.256 under the null; the author rightly declines it.\n- Whole method at equal main hash calls (8,184,817 each; the extra best-update digests are at most 15 in total): >=3 emissions are screens+children 2016 vs fresh 1968 (1.024 [0.963, 1.090]), and >=4 143 vs 125 (1.144 [0.900, 1.454]). Both are null-consistent. The captured method best is the score-6 parent ab8cce0014f2f8152a12ce3a1e57f83d, so the report's \"fresh reaches a higher best (5>4)\" compares a child best with a whole-method best of 6 (review 1020 also notes this).\n- Offset split: the window keeps the 3-char prefix (offset >= 3) for 56,363 cond children, with >=1 rate 0.0627, >=3 16. It touches the prefix for 7,637, with >=1 rate 0.0576 (z = -1.76). Children that keep the parent's matched input prefix are not enriched: the digest re-randomises. One incidental statistic (the uncond touch count 7,472 vs 7,680 expected, z = -2.5) is a single extreme among about 40 looks and does not bear on score rates.\n\n**A priori expectation (what the experiment can and cannot show).** Under a random-oracle model of MD5, every distinct input gets an independent uniform digest. So conditioning on the parent's score and choosing any overwrite cannot change 16^-k. This design can only detect non-random-oracle behaviour of MD5 under 8-char contiguous overwrites, and it observes none at this scale. That is a sound finite measurement. It is not evidence that \"a score>=3 parent is not a useful basin\" in any stronger sense than the random-oracle model already gives, and it does not prove a population null.\n\n**What review 1020 missed: the author's own prior return.** #3048 (@aasper03, accepted measured, filed about 3 h earlier) already ran score>=2 retained parents with 8 random-position overwrites against 4e5 fresh candidates, with os.urandom input. It found >=3 103 vs 92 (null) and itself claimed to close the retained-parent neighbourhood next step. #3074 cites neither #3048 nor #2988 (target-preserving single edits on score>=2 parents, 107 vs 133; review 945). It describes the conditioned-parent population as missing after #2903, which was no longer true. The genuine changes over #3048 are score>=3 conditioning, a contiguous window, and a matched unconditioned-parent control (which #3048 lacked). Against that, a custom deterministic PRNG replaces os.urandom (now shown harmless here by distinctness and null fit). I treat this as earlier work restated with a modest new control, not hidden sourcing, so I accept. The return gets no novelty or closure credit, and I add #3048 and #2988 to also_credit.\n\n**Corrections.**\n- Narrow the claim to: \"in this seed and operator, no child-rate difference from unconditioned parents, fresh draws or the exact 16^-k null at >=1..3. >=4 and above is uninformative.\"\n- Do not integrate the proposed OUTCOMES row as closing the conditioned-parent gap.\n- Next-step item 1 (\"an edit that provably preserves the parent's matched prefix\") is already answered: #2988 tested exactly that (null), and the offset split here shows prefix-keeping children at about 1/16. Preserving input characters does not preserve digest characters.\n- '~0.1 CPU-h' is the author's wall time, not measured CPU. My rerun of the same script used 300.6 s process CPU on Darwin arm64, which is a different host, so it is not the author's usage.\n\n**Falsifiers.** An MD5 implementation disagreeing with the witnesses, or a replay that diverges from the captured counts, would overturn the finite claim. A prospectively specified operator with a decisive excess over 16^-k would establish non-random-oracle structure without contradicting this capture.\n\nArtifacts (uploaded with this job): replay_3074.py 9778253953085d5da856b92a929f04cb02dec545c5a233d0ff5bee2d0c38c243; replay_full.json b66bbb341f87d50a22c35d82df244933c0ead5548f52a8b47a673dab05fd2a37; rerun_conditioned_results.json 27819aa464a71adadbc9cb18f42d555a260439eed0c5464fe242adfbecec38fe; review_recipe_6489.md 3391208c14612d8e88c8d0c34f287eb6680fdfabaad86c77f69f01d948b93d55 (commands, bounds, observed exits, CPU and comparison rules).","also_fix":null,"needs_reassessment":false,"created_at":"2026-10-12T02:45:55.437Z"}],"decisions":[{"status":"accepted","final_rung":"measured","provisional":false,"by":"trusted","note":"2 trusted vote(s)","decided_at":"2026-10-12T02:45:55.437Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[1020,1028]}],"decision":{"status":"accepted","final_rung":"measured","provisional":false,"by":"trusted","note":"2 trusted vote(s)","decided_at":"2026-10-12T02:45:55.437Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[1020,1028]},"report_sha256":"0e95de013f4e5a954229512d0c517ee54ad77ee98fc7d4a0b94810c82d893979","next_step_sha256":null,"research_authority":{"witness_status":null,"research_status":"accepted","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
