copy_last 两级增殖重加权(β_type=-4、β_cell=-1)+ 类型内增殖-表达 OLS 斜率的逐细胞放大(γ=-1.6、|slope|>0.15);PLAN 的分解式调整(类型均值平移 γ_mean + 衰减 γ_dev)实测正负两向均降分,γ_dev 与 β_cell 局部扫描亦全部低于基线,确认父配置为局部最优,发布输出与节点 23 逐字节等价。

方法(继承节点 4/6/7/18/23,已多节点验证)

输出 = 最新「官方」输入阶段的加权无放回抽样(Efraimidis–Spirakis,n=max_cells)。权重两级相乘:

  • 类型级 w_type = max(1e-6, 1 + β_type·(prolif_type − mean_prolif)),β_type = -4;
  • 细胞级 w_cell = max(1e-6, 1 + β_cell·(prolif_cell − prolif_type)),β_cell = -1。

prolif 得分 = 通用 cell-cycle 基因(Mki67, Top2a, Pcna, Cdk1, Ccna2, Ccnb1, Aurkb, Bub1, Cenpf, Nusc1;与面板取交集,≥3 个才启用)log 表达逐细胞均值,完全在输入快照内计算,单阶段可用(proxy 退路)。生物学依据:增殖-分化权衡是通用发育机制(非阶段特异知识),来源为通用细胞周期基因注释(GO cell cycle / Reactome Cell Cycle 通路的核心基因名,不针对禁窗)。

表达调整:每类型(≥20 细胞)内 OLS slope_g = cov(x_g, prolif)/var(prolif),只保留 |slope_g| > 0.15;每个被选细胞 x_adj[i,g] = x[i,g] + slope_g·(γ_mean + γ_dev·(tmean − p_i)),clip ≥0,1024 行分块。发布配置 γ_mean=0、γ_dev=-1.6(外部阶段与退化视图跳过调整,X3 上实测有害 50.0→43.2)。

本节点做的事(PLAN:分解式斜率调整)——假设被证伪,全部关闭

PLAN 假设:γ_mean(类型内一致的均值平移,不增加类型内方差)能抬 direction 且不伤 covariation,同时可减小 |γ_dev| 保护协变结构。实测(A 半 proxy seed0,基线 γ_mean=0 → 57.60):

+0.553.6446.8457.24
+0.847.8137.6246.71
−0.356.1051.4558.72

正负两向单调降分,且 covariation 与 cell_state 同步受损 → 类型均值平移把质心推离真值位置,机制假设不成立。按 PLAN 预定判定(无一超过 57.6)应中止;补充的 γ_dev / β_cell 扫描亦确认基线为峰值:

  • γ_dev=-1.2 → 57.41(cov 53.81↑ 但 cell_state 62.02↓,等 board trade-off,与 node 26 结论一致);γ_dev=-2.0 → 57.56。
  • β_cell=-0.5 → 56.83;β_cell=-1.5 → 56.21。

故默认 GAMMA_MEAN=0、GAMMA=-1.6、BETA_CELL=-1、SLOPE_MIN=0.15,输出与节点 23 逐字节相同(md5 已核)。γ_mean 参数保留(--gamma-mean)可复现。

查分记录(A 半,本节点 13 次查询)

  • proxy seed0 基线:57.60(de_recovery 52.48 / direction 59.67 / cell_state 62.87 / covariation 53.5)
  • proxy2 seed0:输出与 proxy 逐字节相同(md5 一致,外部 Qiu E9.0 被 pick_stage 忽略),未重复查分
  • X3 seed0:50.0(退化+外部保护生效,= copy_last)
  • 参数扫描 9 次:见上表(gm+0.3/+0.5/+0.8/−0.3、gd−1.2/−2.0、bc−0.5/−1.5,另 4 次为重复捕获输出)

验证过

  • 三视图(proxy / proxy2 / X3)跑通、vec-check 全 ok、~4.3 s、内存远低于限额。
  • 确定性:仅 np.random.default_rng(seed);γ_mean=0 默认路径与父节点 md5 相同。
  • proxy ≡ proxy2(逐字节),X3 = 50.0 保底。

没验证 / 风险

  • 本节点为已确认的 null result:发布配置与节点 23 完全相同,B 半分数预期 ≈54.7(3 种子均值 54.68),无过拟合新风险。
  • γ_mean 的证伪基于单 seed A 半,但降幅(−1.4 至 −9.8)远超 T1 噪声(~2 分,除 γ_mean=+0.3/−0.3 外),方向性结论可靠;±0.3 档也在噪声边缘以下且无正向信号,未做多种子确认。
  • final 视图(E8.5+E9.5→E10.5)未测:逻辑与 proxy 相同(取最新官方阶段),若 E9.5 池 ≤ 目标细胞数则退化保护退回 copy_last,安全。

对后续节点的建议

该家族(copy_last + 增殖重加权 + 斜率表达调整)的参数空间已被 10+ 节点扫尽:γ、γ_mean、γ_dev、β_type、β_cell、slope_min、PC 投影、top-N、通路平滑全部在 (−4,−1,−1.6,0.15,0) 处达到局部峰值,covariation↔cell_state 是等 board trade-off 曲线。继续调参预期收益为 0;建议换机制家族(如细胞类型组成层面的出生/改名模型、或 OT 到增殖轴的分层抽样)。

调研员的计划

名称Decomposed slope adjustment: type-mean shift + attenuated cell-deviation
动机Parent node 23 (score 54.73) has covariation 52.58 and direction 56.23 as the weakest responsive groups (de_recovery 51.69 is confirmed immune to all perturbations across 7+ nodes). The current expression adjustment x_adj[i,g] = x[i,g] + γ·slope_g·(tmean_prolif - p_i) with γ=-1.6 is purely cell-specific: since mean(tmean - p_i)=0 within each type, the adjustment has ZERO type-mean shift and only redistributes variance within types. This cell-specific perturbation is the likely source of covariation disruption (gene-gene correlations distorted by heteroscedastic per-cell noise) while providing no directional mean shift. Node 26 showed that reducing the number of adjusted genes (top-N) trades covariation for cell_state at equal board score, confirming the adjustment itself is the covariance bottleneck. A type-level uniform shift along the slope vector is a fundamentally new degree of freedom: it moves each type's centroid in gene space (helping direction) without adding within-type variance (preserving covariation), while allowing γ_dev to be reduced.
做法Modify the expression adjustment in run.py to decompose into two components:

1. Type-mean shift: x_adj[i,g] += γ_mean · slope_g (uniform for all cells of a type, where |slope_g| > SLOPE_MIN). This shifts the type centroid along the proliferation-expression coupling direction. Since it's uniform within a type, it does NOT change within-type covariance.

2. Cell-deviation: x_adj[i,g] += γ_dev · slope_g · (tmean_prolif - p_i). This is the existing mechanism, but with γ_dev as a separate (potentially smaller) parameter.

Full formula: x_adj[i,g] = x[i,g] + slope_g · (γ_mean + γ_dev · (tmean_prolif - p_i)), clipped ≥ 0, only for |slope_g| > 0.15.

Parameter search (A-half proxy seed0, ~4.4s per run):
- Phase 1: Fix γ_dev = -1.6 (current), sweep γ_mean ∈ {0.0, 0.3, 0.5, 0.8, 1.0, 1.5}. If γ_mean > 0 helps, proceed.
- Phase 2: Fix γ_mean at best, sweep γ_dev ∈ {0.0, -0.4, -0.8, -1.2, -1.6}. Hypothesis: smaller |γ_dev| preserves covariation while γ_mean maintains direction/cell_state.
- Phase 3: If a combination improves board by >2 (noise threshold), verify with seed1. If improvement is <2, test 3 seeds to confirm.

Single-stage fallback: all computation uses within-snapshot proliferati…
风险1. γ_mean may disrupt cell_state if the type-mean shift moves cells away from their true target positions (the slope direction may not align with the actual developmental trajectory for all types). Engineer should check cell_state group in every vec-score query; abort if cell_state drops >2 from 57.46.
2. The covariation score may be insensitive to within-type covariance changes if it measures cross-type correlations instead. If γ_dev reduction doesn't improve covariation after 2-3 runs, the mechanism assumption is wrong; revert to parent config.
3. Improvement may be <2 (noise). If Phase 1 shows all γ_mean values within ±1 of baseline, skip Phase 2 and report null result with 2-seed confirmation.
4. γ_mean > 0 with negative slopes could push some genes' expression in the wrong direction. The clip ≥ 0 handles this, but many clipped genes could create artifacts. Monitor: if >20% of adjusted values are clipped for any type, reduce γ_mean.
5. Early detection: after first 5 parameter combinations, if none exceed board 57.6, abort and report.

分析结果?分析员写的 ANALYSIS.json:改了什么、各组分数怎么变、假设是否成立、经验和下一步建议。

改了什么实现了 PLAN 的分解式斜率调整:新增 --gamma-mean 参数,调整公式变为 x_adj += slope_g·(γ_mean + γ_dev·(tmean−p_i))。A 半扫描 γ_mean∈{+0.3,+0.5,+0.8,−0.3} 全部降分(56.24/53.64/47.81/56.10 vs 基线 57.60),另扫 γ_dev∈{−1.2,−2.0}(57.41/57.56)与 β_cell∈{−0.5,−1.5}(56.83/56.21)也均低于基线,故发布配置 γ_mean=0,输出与父节点 23 逐字节相同(md5 已核)。
各组分数的变化board:不变 +0.00(54.73),发布输出与父节点逐字节相同,非噪声问题而是完全同一输出
cell_state:不变 +0.00(57.46),A 半扫描中 γ_mean 与 γ_dev 变化均使 cell_state 与 covariation 同步受损或等 board trade-off
covariation:不变 +0.00(52.58),γ_dev=−1.2 时 A 半 cov 升至 53.81 但 cell_state 降至 62.02,board 反降(57.41<57.60)
de_recovery:不变 +0.00(51.69),与全树 7+ 节点一致,对表达级扰动免疫
direction:不变 +0.00(56.23),γ_mean 均值平移未能抬升 direction,A 半实测反而随 |γ_mean| 增大单调降分
假设是否成立否
经验
  1. 在 copy_last+增殖重加权+斜率调整家族上,对每类型加沿 slope 的一致均值平移(γ_mean):正负两向(±0.3~0.8)全部使 A 半 board 从 57.60 降至 47.8~56.2,且 covariation 与 cell_state 同步受损,说明 slope 方向不与真实发育轨迹对齐,类型质心平移推离真值。
  2. 减小 |γ_dev|(−1.6→−1.2)确实抬 covariation(53.5→53.81)但等量压低 cell_state(62.87→62.02),board 净降,与 node 26 结论一致:该家族内 covariation↔cell_state 是等 board trade-off 曲线,无法同时改善。
  3. β_cell 在 −1 处为局部峰值(−0.5→56.83,−1.5→56.21),加上此前 γ、β_type、slope_min、PC 投影、top-N、通路平滑的扫描,(β_type,β_cell,γ,slope_min,γ_mean)=(−4,−1,−1.6,0.15,0) 已被 10+ 节点确认为该机制家族的局部最优,继续调参预期收益为 0。
  4. 在参数扫描全部低于基线时按 PLAN 预设阈值(无一超 57.6)中止并回退到父配置发布,是正确做法:节点状态为 scored 且零风险,同时留下了完整的证伪记录。
下一步建议
  1. 停止在该家族内调参(所有分组均已在局部峰值),换机制家族:针对 covariation/direction,尝试类型组成层面的改动(如基于增殖轴的细胞出生/类型改名模型)重构群体比例,而非仅重加权抽样。
  2. 针对 cell_state/covariation,尝试最优传输(OT)或分层抽样沿增殖轴重新分配细胞到类型,替代逐细胞表达修改,避免破坏基因间协方差。
  3. de_recovery(51.69)已确认对表达级扰动完全免疫(7+ 节点不动),后续不要再把资源花在该组的表达调整上,若要改善需从 DE 基因选择/伪时间对齐等不同机制入手。

最后的回答(摘录)
完成。

**做了什么**:实现 PLAN 的分解式斜率调整(类型均值平移 γ_mean + 细胞偏离项 γ_dev,`--gamma-mean` 参数),在 proxy A 半扫描 γ_mean∈{+0.3,+0.5,+0.8,−0.3}、γ_dev∈{−1.2,−2.0}、β_cell∈{−0.5,−1.5}(13 次查询)。

**查分结果**:γ_mean 正负两向全部降分(56.24/53.64/47.81/56.10 vs 基线 57.60),covariation 与 cell_state 同步受损,PLAN 假设被证伪;γ_dev、β_cell 扫描也确认父配置 (−1.6, −1) 为峰值。发布输出与节点 23 逐字节相同(proxy 57.60 / proxy2 md5 一致 / X3 50.0,三视图 vec-check ok,~4.3s)。

**下一步建议**:该家族参数空间已被 10+ 节点扫尽,covariation↔cell_state 是等 board trade-off,继续调参预期收益为 0;应换机制家族(类型组成级出生/改名模型,或沿增殖轴的 OT/分层抽样重构群体)。

最后的回答(摘录)
. For X3/external/degenerate: existing guard skips adjustment entirely.\n\nvec-score usage: run `vec-score` after each parameter combination on proxy A-half seed0. Compare board and 4 group scores. Only advance combinations with board ≥ 57.6 (current A-half) AND covariation ≥ 53.0.\n\nImplementation: add two CLI args --gamma-mean (default 0.0 for backward compat) and --gamma-dev (default None, falls back to --gamma / GAMMA). Modify the adjustment loop: precompute slope vector per type as before, then apply x_adj += slope * (gamma_mean + gamma_dev * (tmean - p_i)). The gamma_mean term is a constant vector added to all cells of a type (vectorized, no extra loop). Memory and time impact negligible (<0.1s).\n\nTotal Engineer time estimate: 10 min implementation, 15 min parameter sweep (~20 runs × 4.4s + vec-score queries), 5 min verification. Fits within 30 min.",
  "expected_groups": ["direction", "covariation"],
  "risks": "1. γ_mean may disrupt cell_state if the type-mean shift moves cells away from their true target positions (the slope direction may not align with the actual developmental trajectory for all types). Engineer should check cell_state group in every vec-score query; abort if cell_state drops >2 from 57.46.\n2. The covariation score may be insensitive to within-type covariance changes if it measures cross-type correlations instead. If γ_dev reduction doesn't improve covariation after 2-3 runs, the mechanism assumption is wrong; revert to parent config.\n3. Improvement may be <2 (noise). If Phase 1 shows all γ_mean values within ±1 of baseline, skip Phase 2 and report null result with 2-seed confirmation.\n4. γ_mean > 0 with negative slopes could push some genes' expression in the wrong direction. The clip ≥ 0 handles this, but many clipped genes could create artifacts. Monitor: if >20% of adjusted values are clipped for any type, reduce γ_mean.\n5. Early detection: after first 5 parameter combinations, if none exceed board 57.6, abort and report."
