XARTATOMS 研究 M104（草帽星系）的热气体晕：用 XMM-Newton 与 Chandra 的 X 射线光谱，测出晕内气体的温度、密度、熵随半径的分布，并检验“引力束缚的静力气体”与“反馈加热的风”两种图景。数据是 XMM 的三次观测（中心 0900170101 加两个偏置指向），拟合用 Sherpa 的 APEC 热等离子体模型加多种背景成分。当前科学基线是 v18 拟合管线。
XARTATOMS studies the hot-gas halo of M104 (the Sombrero Galaxy): using X-ray spectra from XMM-Newton and Chandra it measures how the temperature, density and entropy of the halo gas change with radius, and tests the two competing pictures — a gravitationally bound hydrostatic gas versus a feedback-heated wind. The data are three XMM observations (central 0900170101 plus two offset pointings); the fitting uses Sherpa with an APEC thermal-plasma model plus several background components. The current science baseline is the v18 fitting pipeline.

四问目标（2026-10-14 PI 新增）
The four-question objectives (added by the PI on 2026-10-14)

|---|---|---|---|---|---|---|
| Q-AQ-A | 哪种本地拟合策略给出的投影温度可靠？ | Which local fitting strategy gives a reliable projected temperature? | QuestionedQuestioned | 内区（2–4′）参考 = MOS2 单相机（S3）：四个背景错设臂全部通过（偏差 +0.008…+0.014 keV，覆盖率 0.71–0.77）；8–10′ 无策略合格（kT ≤ 1 keV 上界撞墙 4–11%，CXB×1.1 偏差 +0.035 keV）；视场边缘与 2D 图未合格；红队 RT-02 后 D48 收窄为 Questioned（MOS2 优于 MOS1 成立，但 MOS2 自身未被证明干净 — D50/T159）— cognition-os/insights/I067_*.md；cognition-os/04_DECISION_LOG.md D50。新增（2026-10-16，R020/D64/B024）：PI 提出“v2 mask 把盘侧遮得太狠”，mask 深度阶梯阶段 A 检验后被红队 RT-17 推翻——v18 实际把源幂律（SrcPo）固定在 0，所谓“轻 mask 只偏 ≤ 0.012 keV”需要一个 v18 没有的自由幂律成分；按 v18 的真实合同，只遮延展源+恒星会把 2–4′ kT 推高 +0.18…+0.22 keV → 全套 v2 点源 mask 在所有 v18 合同谱、Fe-L 硬度与 2D 图上继续使用，窄阶段 B 取消。教训：写 brief/决策前必须读模型成分的最终状态（所有 set/freeze 之后），不能只读声明（B024） |
Inner (2–4′) reference = MOS2-only (S3): passes all four background-misspecification arms (bias +0.008…+0.014 keV, coverage 0.71–0.77); 8–10′ none qualified (kT ≤ 1 keV bound hits 4–11 %, CXB×1.1 bias +0.035 keV); edge and the 2D map unqualified; after red team RT-02, D48 is narrowed to Questioned (MOS2 preferred over MOS1 stands, but MOS2 itself is not shown clean — D50/T159) — cognition-os/insights/I067_*.md; cognition-os/04_DECISION_LOG.md D50. New (2026-10-16, R020/D64/B024): the PI asked whether the v2 mask masks the disk side too hard; the mask-depth-ladder stage A test was overturned by red team RT-17 — v18 as run freezes the source power law (SrcPo) at 0, so the "lighter mask biases kT by only ≤ 0.012 keV" result needs a free power-law component that v18 does not have; under the literal v18 contract, masking only extended sources + stars pushes the 2–4′ kT up by +0.18…+0.22 keV → the full v2 point mask stays for every v18-contract spectrum, the Fe-L hardness and the 2D maps, and the narrow stage B is cancelled. Lesson: read a model component's final state (after all set/freeze lines), not its declaration, before writing a brief or a decision (B024) |

| Q-BQ-B | Chandra+XMM 联合的 M104 温度 profile 是什么（10′ 内）？ | What is the Chandra+XMM kT profile of M104 (within 10′)? | First profileFirst profile | 径向 kT 问题（升 vs 平）开放，只由预注册的匹配合同测试（D55）判定：扇区谱外热（A2 +0.22 / A1 +0.37 keV 点对比，外区未合格）；单温 Fe-L 硬度平（0.77–0.79 keV，2–12′，I068/T160；两相混合可给出同样 H，RT-06）；Chandra-only 与单一温度 0.725 keV 一致（p = 0.54，D56；内环在 I3 瞄准芯片、外环在 FI 芯片，D61 更正 S3 说法；污染模型版本影响 ≤ 0.012 keV）——但红队 RT-23 已分诊（R028/D69）：这条不能用来反对 XMM 的外升，因为 Chandra 2–10′ 的“环”其实只有 35–62% 的部分环带（8–10′ 的两个 ObsID 各盖对面一半），而共同 kT 检验探不到 ΔkT ≲ 0.27 keV 的差（8–10′ 的 95% 上界 0.954 keV 包含 XMM 的 0.90）→ “Chandra 等温”既没有匹配的孔径、也没有功率去证实或否证 XMM 的升；“张力 = 合同不匹配”已撤回（R009）；测试暂停：Virgo 阶段 1 的口径谱缺 v2 mask（B023）→ 阶段 1b 重抽（曾被 Virgo 网络中断挡住，08:39Z 恢复）；红队 RT-15（0.7 keV 前景成分：v18 该槽位实为 0 且冻结 → D62 只是外区 kT 的附带假设）与 RT-16（固定 Z = 0.3：Z = 1.5 真值按 Z = 0.3 拟合在 8–10′ 只低 0.017 keV → 不是外升成因，D63；阶段 5 把 Z = 1 与 Z 自由作次要诊断）已分诊 → 待定的是阶段 5 本身 — cognition-os/04_DECISION_LOG.md D55/D56/D62/D63/D69 |
The radial kT question (rise vs flat) is open, decided only by the pre-registered matched-contract test (D55): sector spectra are hotter outside (A2 +0.22 / A1 +0.37 keV point contrasts, outer unqualified); the one-temperature Fe-L hardness is flat (0.77–0.79 keV over 2–12′, I068/T160; a two-phase mixture can give the same H, RT-06); Chandra-only is consistent with one temperature 0.725 keV (p = 0.54, D56; the inner ring is on the I3 aim-point chip and the outer ring on FI chips — D61 corrects the "S3" wording; the contamination-model version moves kT by ≤ 0.012 keV) — but red team RT-23 is triaged (R028/D69): this cannot be used against the XMM rise, because the Chandra 2–10′ "rings" are only 35–62 % partial annuli (the two 8–10′ ObsIDs cover opposite halves) and the common-kT test cannot detect a ΔkT below ≈ 0.27 keV (the 8–10′ 95 % upper bound of 0.954 keV contains the XMM 0.90) → "Chandra isothermal" has neither a matched aperture nor the power to corroborate or refute the XMM rise; "tension = contract mismatch" is withdrawn (R009); the test is paused: the Virgo stage-1 aperture spectra lack the v2 mask (B023) → stage 1b re-extracts them (blocked for a while by a Virgo network outage, resumed 08:39Z); red teams RT-15 (a 0.7 keV foreground component: that v18 slot is actually 0 and frozen → D62 is only a stated assumption for the outer kT) and RT-16 (fixed Z = 0.3: a Z = 1.5 truth fitted with Z = 0.3 reads only 0.017 keV low at 8–10′ → not the cause of the rise, D63; stage 5 reports Z = 1 and Z-free as a secondary diagnostic) are triaged → what is pending is stage 5 itself — cognition-os/04_DECISION_LOG.md D55/D56/D62/D63/D69 |

| Q-CQ-C | 为何 ~13′ 亮度反而比内侧和 15–30′ 更亮？ | Why is the intensity brighter at ~13′ than inside and at 15–30′? | Resolved: artefactResolved: artefact | 假象（Provisional，I065）：flux 已是每 arcmin²（B020），旧 flux/area 双重归一；裸 SB 比 1.37，冻结 kT 后 1.07；图像 1.041±0.068 无超出；WARP 星系团拟合为 0 — cognition-os/insights/I065_*.md；经受住红队 RT-01（4 条次要、0 条实质；图像检验 −2.7σ 支持无超出，I065 修订）；开放：外环拟合方法；15–45′ profile 为 Questioned（E039：偏移拟合简并/不自洽，需 0501 ODF + Virgo 重处理） |
Artefact (Provisional, I065): the saved flux is already per arcmin² (B020), so the old flux/area double-normalised; bare-SB ratio 1.37, 1.07 with kT frozen; images 1.041±0.068 show no excess; the WARP cluster fits to 0 — cognition-os/insights/I065_*.md; it survived red team RT-01 (4 minor, 0 material objections; the image test at −2.7σ supports no excess, I065 amendment); open: the outer-ring fit method; the 15–45′ profile is Questioned (E039: offset fits degenerate/inconsistent; needs the 0501 ODF + Virgo re-reduction) |

Intensity map done; the 2D proxy map (stage 2, E038): Fe-L × quadrant anchors; the joint MOS2+pn0 minor-axis vs disk contrast lies within ≲ 0.08–0.11 keV (calibrated intervals, radius/geometry-dependent, asymmetric: ±45° 2–5′ [−0.056,+0.076] keV) — the contrast response R≈0.67–1.0 sets the sensitivity; N>S is only a hint (cross-arm familywise p≈1), not a detection (E038 + RT-07 amendment) — cognition-os/experiments/E038_*.md (D49). New (2026-10-16): 2D intensity (E042/R016) — the 2–5′ disk-aligned asymmetry (minor/disk 0.674 ± 0.100) is consistent with smooth β ellipticity (injection prediction 0.752 [0.656, 0.846]); a ≥ +30 % minor-axis bicone is excluded at 2–5′; 2D kT (E043/R018) — the best estimator is the Fe-L 2-band + MOS1 (free normalisation) on cone45 bins (σ ×1.12, unbiased in injections), but only on the 3-camera common footprint (56 % of the area); the second arm agrees; the production maps (P12/E045) replay stage 3 exactly and read: no minor-axis vs disk contrast at 2–5′, an inner N−S +0.10 keV hint (one method only, pending; the East arrow was once drawn toward West — the fix is in progress and the map is not shown until it is). The folded 2D kT map v2 (E046/T171, Provisional; see state §2h): the four quadrants folded about the optical major/minor axes (≈4× counts per bin), primary estimator E1 = MOS2 + pn0, the v2 mask applied throughout; the per-bin kT over 2–12′ has a median band of 0.70–0.80 keV (per-bin range 0.53–0.89 keV; global 0.736 keV [0.723, 0.748]; 8/21 bins outside the band — wording narrowed per RT-20/D68/R025) and the all-angle slope is +0.009 keV/arcmin (95 % [−0.003, +0.020], +1.5σ) → no inner-cool/outer-hot trend at ≥ 2σ for this one-temperature proxy; a gradient of +0.1 keV per 5′ would be detected 91 % of the time (disfavoured at ≈ 95 %, but for the one-temperature proxy only — that proxy hides 13–18 % of a real rise); the disk wedge's outer cells 0.85–0.88 vs the minor wedge 0.61–0.77 keV are suggestive only (≈ 1.4σ, pn0-driven, near the field edge); MOS2 and pn0 agree bin by bin (p = 0.60); scaling pn0's QPB to M104's own 0.772 ± 0.016 pushes the slope to ≈ 2σ → the trend is background-sensitive (the scaling is test-only); the core inside 2′ is masked, so a cooling flow cannot be tested here; E045's inner N−S +0.10 keV hint is downgraded to Questioned after RT-19's multiplicity check (R022) — cognition-os/experiments/E046_*.md |

未来 1–4 周计划
Plan for the next 1–4 weeks
计划完全来自 cognition-os/02_CURRENT_QUESTION.md（2026-10-16 节，只保留当前状态）与各 job 的 BRIEF/REPORT，不是本手册的发明。2026-10-16 09:39Z 更新：Q-B 的决定性检验是 D55 预注册的匹配合同测试（规则已在任何阶段 5 拟合前冻结），但它暂停——Virgo 阶段 1 的口径谱只有自动 mask（B023），阶段 1b 在重抽（Virgo 网络中断 ≈06:45–08:3xZ，08:39Z 恢复）；Chandra-only 与单一温度 0.725 keV 一致（D56/D61），“合同不匹配”表述已撤回（R009）；Q-D：2D 强度阶段 2 完成（E042/R016：2–5′ 不对称与 β 椭圆率一致，≥+30% 双锥被排除），2D kT 阶段 3 完成（E043/R018：估计器 E3 + cone45，双臂一致，共同足迹 56%），生产图运行中；mask 深度阶梯阶段 A 的"内区谱可轻 mask"结论被 RT-17 推翻（R020/D64：v18 无自由源幂律，轻 mask 偏 +0.18…+0.22 keV → 全套 v2 mask 保留，阶段 B 取消）；红队 RT-15（D62）、RT-16（D63：Z 不是外升成因）、RT-17（R020/D64）已分诊；RT-18（v18 合同逐成分审计，阶段 5 前必做）与 RT-19（2D kT 生产图）运行中（待定）。
The plan comes entirely from cognition-os/02_CURRENT_QUESTION.md (2026-10-16 section, current state only) and the job briefs/reports; it is not invented by this handbook. Update 2026-10-16 09:39Z: Q-B's decisive test is the D55 pre-registered matched-contract test (its rule frozen before any stage-5 fit), but it is paused — the Virgo stage-1 aperture spectra carry only the automatic mask (B023) and stage 1b is re-extracting them (Virgo network outage ≈06:45–08:3xZ, resumed 08:39Z); Chandra-only is consistent with one temperature 0.725 keV (D56/D61) and the "contract mismatch" headline is withdrawn (R009); Q-D: 2D intensity stage 2 done (E042/R016: the 2–5′ asymmetry is consistent with β ellipticity, a ≥ +30 % bicone is excluded), 2D kT stage 3 done (E043/R018: estimator E3 + cone45, both arms agree, common footprint 56 %), the production maps are running; mask-depth-ladder stage A's "lighter mask safe for inner spectra" conclusion was overturned by RT-17 (R020/D64: v18 has no free source power law, a lighter mask biases +0.18…+0.22 keV → the full v2 mask stays, stage B cancelled); red teams RT-15 (D62), RT-16 (D63: Z is not the cause of the rise) and RT-17 (R020/D64) are triaged; RT-18 (a per-component audit of the v18 contract, required before stage 5) and RT-19 (the 2D kT production maps) are running (Pending).

本次更新
What's new
- 2026-10-16 20:5xZ（阶段 12：E047 措辞按 RT-24 收窄 + RT-23/RT-25 分诊）：P18 端到端模拟的功率必须按统计量分开引（E047/T172/R026，Provisional 暂定；R029/D70）——那个 “0.70 → 0.90 keV 的向外升在 93.5% 的实现里以 ≥ 2σ 被探测到” 说的是全角度 2–12′ 斜率；与真实折叠图上逐楔 2–8′ 检验对应的统计量功率只有 27–36%（大轴/中轴/小轴楔 0.34/0.355/0.27）→ 真实图“没看到”这种上升，并不排除单个楔里存在它；93.5% 在修掉一次重复计算 vignetting 的归一化错误之前是 62%。模拟真值的折叠网格与拟合器逐位相同 → 响应误差未测。S7b 在逐点 99%（Holm 后 97%）上被否定，但真实数据的盘 − 小轴差（−0.030 keV）与 S7b 自己的（−0.036）几乎相同 → 被否定的只是 S7b 那条径向律，不是冷却流这个大类；S7a/S7c 不能被稳健排除（S7a 的 p = 0.045/0.065/0.075，随背景 −10/0/+10% 而变）。两相 S6 的单温 Fe-L 偏差按臂而变：+0.067 keV（sol）vs +0.172 keV（独立臂） → 引作范围。红队：RT-23（Q-B 的 Chandra 半边）已分诊 → R028/D69：Chandra 2–10′ 的“环”其实只有 35–62% 的部分环带（8–10′ 的两个 ObsID 各盖对面一半），共同 kT 检验探不到 ΔkT ≲ 0.27 keV 的差 → “Chandra 等温”不能用来反对 XMM 的外升；RT-24（E047 模拟）与 RT-25（mask/强度）已分诊 → R029/R030/D70；RT-26（OS 一致性）与 RT-27（拟合能段/P16）运行中（待定）。mask（R030）：D64“保留全套 v2 mask”的判定不变，但“不用全套点源 mask 会偏 +0.2 keV”这条是在 0.4–3.2 keV 上量的，而 as-run 拟合 notice 的是 0.375–9.0 keV；被 mask 挡掉的光主要是 M104 自身的光与恒星 → 机制待定，待 as-run 能段重拟合。
- 2026-10-16 20:5xZ (stage 12: the E047 wording narrowed after RT-24 + the RT-23/RT-25 triage): the P18 mock's power must be quoted per statistic (E047/T172/R026, Provisional; R029/D70) — the "0.70 → 0.90 keV outward rise is detected at ≥ 2σ in 93.5 % of the draws" refers to the all-angle 2–12′ slope; the statistic matching the real folded map's per-wedge 2–8′ test has a power of only 27–36 % (major/middle/minor wedge 0.34/0.355/0.27) → the real map's failure to see such a rise does not exclude it inside a single wedge; the 93.5 % was 62 % before a double-counted vignetting normalisation was fixed. The mock truth's folding grid is bit-for-bit the fitter's → response error is untested. S7b is disfavoured at 99 % pointwise (97 % after Holm), but the real data's disk − minor difference (−0.030 keV) is essentially the same as S7b's own (−0.036) → what is rejected is the S7b radial law, not cooling flow as a class; S7a/S7c cannot be robustly excluded (S7a's p = 0.045/0.065/0.075 as the background moves −10/0/+10 %). The two-phase S6 one-temperature Fe-L bias is arm-dependent: +0.067 keV (sol) vs +0.172 keV (independent arm) → quote it as a range. Red teams: RT-23 (the Chandra half of Q-B) is triaged → R028/D69: the Chandra 2–10′ "rings" are only 35–62 % partial annuli (the two 8–10′ ObsIDs cover opposite halves) and the common-kT test cannot detect a ΔkT below ≈ 0.27 keV → "Chandra isothermal" cannot be used against the XMM rise; RT-24 (the E047 mock) and RT-25 (mask/intensity) are triaged → R029/R030/D70; RT-26 (OS consistency) and RT-27 (fit band / P16) are running (Pending). Mask (R030): the D64 verdict "keep the full v2 mask" stands, but the "+0.2 keV bias without the full point mask" was measured on 0.4–3.2 keV while the as-run fit notices 0.375–9.0 keV; the light the mask removes is mostly M104's own light and stars → the mechanism is open (Pending), awaiting a refit on the as-run band.
- 2026-10-16 14:2xZ（阶段 10：折叠 2D kT 图 v2 + v18 合同更正）：PI 12:2xZ 要求的四象限折叠 2D 温度图 v2已出（E046/T171，Provisional 暂定，首页与状态页 §2h 六图）——四象限关于光学长/短轴折叠（每箱约 4 倍计数，对称性经 N−S/E−W 两半检验，1–2 个 5–7′ 30–60° 箱不安全 → 天空面板只叫"对称模型展示"）；2–12′ 的逐箱 kT 中位带为 0.70–0.80 keV（逐箱范围 0.53–0.89 keV，全局 0.736 keV，8/21 箱在带外——措辞按 RT-20/D68/R025 收窄），全角度斜率 +0.009 keV/角分（95 % [−0.003, +0.020]，+1.5σ）→ 对这种单温代理而言无 ≥ 2σ 的内冷外热；每 5′ 升 0.1 keV 的梯度 91% 可被探测（只对单温代理成立）；盘楔外箱 0.85–0.88 vs 小轴楔 0.61–0.77 keV 只是提示（≈ 1.4σ，pn0 主导）；MOS2 与 pn0 逐箱一致（p = 0.60）；pn0 QPB 按 M104 自己的 0.772 ± 0.016 缩放（测试用）把斜率推到 ≈ 2σ → 趋势对背景敏感；< 2′ 核被 v2 mask 遮住，冷却流在此不可检验（D66 定义 + P18 模拟，待定）；E045 的内区 N−S +0.10 keV 提示经 RT-19 多重比较后降为 Questioned（R022）。v18 合同更正（B025/R023，RT-18 重放）：v18 实际拟合源 0.375–9.0 keV、背景 0.375–6.23 keV（脚本注释的 0.4–3.2 keV 是错的，Sherpa notice/ignore 取并集）；RASS 过滤器损坏；P16 测量其对已存 kT 的影响（待定，新增开问题行）；mask 阶梯 +0.18…+0.22 keV 数字按 0.4–3.2 keV 测量重新定界（R021），但"保留全套 v2 mask"的判定（D64）不变。红队 19 支已分诊，RT-20（攻击折叠图）/RT-21（B025 后的阶段 5 规格书）运行中。
- 2026-10-16 14:2xZ (stage 10: the folded 2D kT map v2 + the v18-contract correction): the four-quadrant-folded 2D temperature map v2 the PI asked for at 12:2xZ is out (E046/T171, Provisional; home page and state §2h, six figures) — the four quadrants folded about the optical major/minor axes (≈4× counts per bin; the symmetry was tested with N−S/E−W halves and 1–2 cells at 5–7′ 30–60° are unsafe, so the sky panel is called only a "symmetric model display"); the per-bin kT over 2–12′ has a median band of 0.70–0.80 keV (per-bin range 0.53–0.89 keV; global 0.736 keV; 8/21 bins outside the band — wording narrowed per RT-20/D68/R025) and the all-angle slope is +0.009 keV/arcmin (95 % [−0.003, +0.020], +1.5σ) → no inner-cool/outer-hot trend at ≥ 2σ for this one-temperature proxy; a gradient of +0.1 keV per 5′ would be detected 91 % of the time (for the one-temperature proxy only); the disk wedge's outer cells 0.85–0.88 vs the minor wedge 0.61–0.77 keV are suggestive only (≈ 1.4σ, pn0-driven); MOS2 and pn0 agree bin by bin (p = 0.60); scaling pn0's QPB to M104's own 0.772 ± 0.016 (test-only) pushes the slope to ≈ 2σ → the trend is background-sensitive; the core inside 2′ is masked by v2, so a cooling flow cannot be tested here (the D66 definition + the P18 mock, pending); E045's inner N−S +0.10 keV hint is downgraded to Questioned after RT-19's multiplicity check (R022). The v18-contract correction (B025/R023, replayed by RT-18): v18 as run fits source 0.375–9.0 keV and background 0.375–6.23 keV (the script comment's "0.4–3.2 keV" is wrong — Sherpa's notice/ignore take a union); the RASS filter is corrupt; P16 measures its effect on the saved kT (pending, a new open-problem row); the mask ladder's +0.18…+0.22 keV number was measured on 0.4–3.2 keV and is re-scoped (R021), but the "keep the full v2 mask" verdict (D64) stands. 19 red teams triaged; RT-20 (attacking the folded map) and RT-21 (the stage-5 specification after B025) are running.
- 2026-10-16 11:34Z（第三次刷新 + 修正轮 1）：Q-B 只由 D55 预注册的匹配合同测试判定，但暂停——阶段 1 口径谱缺 v2 mask（B023，执行器在任何拟合前抓住）→ 阶段 1b 重抽（内容门已过，引擎恢复合同不允许复用 B3 → 全新整跑）；Chandra-only 与 0.725 keV 等温一致（D56；D61 更正：ACIS-I 全前照芯片，非 S3；污染模型 ≤ 0.012 keV）；E040 事件级复现（ARF +4%）；2D 强度阶段 2 + 注入检验（E042/R016：2–5′ 与 β 椭圆率一致，≥+30% 双锥排除）；2D kT 阶段 3（E043/R018：E3 + cone45，双臂一致，共同足迹 56%）；mask 阶梯"轻 mask"结论被 RT-17 推翻（R020/D64：v18 无自由源幂律 → 全套 v2 mask 保留、阶段 B 取消；B024：两次从声明而非最终状态写前提）；Z = 0.3 不是外升成因（D63：Z = 1.5 真值只低 0.017 keV）；文献表（Li+2007/2011、2026 SZ、Igarashi+2014：平 kT 无法区分束缚气体与慢风）；红队 17 支已分诊，RT-18（v18 合同审计）/RT-19（生产图）运行中。
- 2026-10-16 11:34Z (third refresh + fix round 1): Q-B is decided only by the D55 pre-registered matched-contract test, but it is paused — the stage-1 aperture spectra lack the v2 mask (B023, caught by an executor before any fit) → stage 1b re-extracts them (content gate passed; the engine's resume contract admits no lane reusing B3 → a fresh full run); Chandra-only is consistent with isothermal 0.725 keV (D56; D61 corrects: ACIS-I, all front-illuminated chips, not S3; contamination model ≤ 0.012 keV); E040 event-level reproduction (ARF +4 %); 2D intensity stage 2 + injection test (E042/R016: 2–5′ consistent with β ellipticity, ≥ +30 % bicone excluded); 2D kT stage 3 (E043/R018: E3 + cone45, both arms agree, common footprint 56 %); the mask ladder's "lighter mask" conclusion was overturned by RT-17 (R020/D64: v18 has no free source power law → the full v2 mask stays, stage B cancelled; B024: two premises written from declarations rather than final states); Z = 0.3 is not the cause of the rise (D63: a Z = 1.5 truth reads only 0.017 keV low); the literature table (Li+2007/2011, the 2026 SZ paper, Igarashi+2014: a flat kT profile cannot separate bound gas from a slow wind); 17 red teams triaged, RT-18 (the v18-contract audit) / RT-19 (the production maps) running.
- 2026-10-15 13:09Z（首次 8 小时刷新）：Q-A 阶段 2 裁定内区参考 = MOS2 单相机（D48/I067），外区/边缘/2D 未合格，阶段 3 运行中；Chandra-only profile（E037）与 J-linked profile（T155）每 ≤1σ 一致；亮度图完成；2D 温度图按 D49 转入代理探索；红队 RT-01/RT-02 启动。
- 2026-10-15 21:49Z（第二次刷新）：Q-A 阶段 3（S4 外区/边缘未合格，测试偏差 ≤ 0.05 keV → D51 探索性引用）；阶段 4（8–10′ 张力 = 合同不匹配，I070/D52）；Fe-L 硬度第二方法平温（I068，RT-06 修订：单温反演平，等温性未确立）；2D 代理阶段 2（E038 + RT-07：校准区间 ≲0.08–0.11 keV、N>S 仅提示）；红队 6 支已分诊（RT-01 存活、RT-03 J-linked 非独立、RT-05 mask 61% → D53）；外区 15–45′ profile Questioned（E039）；Virgo 阶段 1 运行中。刷新期间新增（D54，21:55Z）：RT-08 撤回 I070 主表述（→ Questioned）、RT-09 修订 ±0.05 keV 口径（逐拟合 68% ≈ ±0.15 keV、组合压力未测）；RT-04/RT-10 启动；0501/0601 ODF 已下载校验。
- 2026-10-15 13:09Z (first 8-hour refresh): Q-A stage 2 sets the inner reference to MOS2-only (D48/I067), outer/edge/2D unqualified, stage 3 running; the Chandra-only profile (E037) and the J-linked profile (T155) agree within 1σ per ring; the intensity map is done; the 2D kT map moves to proxy exploration per D49; red teams RT-01/RT-02 launched.
- 2026-10-15 21:49Z (second refresh): Q-A stage 3 (S4 outer/edge not qualified, tested biases ≤ 0.05 keV → D51 exploratory quoting); stage 4 (the 8–10′ tension = contract mismatch, I070/D52); the Fe-L hardness second method is flat (I068, RT-06 amendment: the one-T inversion is flat, isothermality not established); 2D proxy stage 2 (E038 + RT-07: calibrated bounds ≲0.08–0.11 keV, N>S a hint only); 6 red teams triaged (RT-01 survives, RT-03 J-linked not independent, RT-05 mask 61 % → D53); the outer 15–45′ profile Questioned (E039); Virgo stage 1 running. During the refresh (D54, 21:55Z): RT-08 withdrew I070's headline (→ Questioned), RT-09 amended the ±0.05 keV wording (per-fit 68 % ≈ ±0.15 keV, the combined stress untested); RT-04/RT-10 launched; the 0501/0601 ODFs downloaded and verified.
- 2026-10-15（阶段 2 修订）：Q-C 13′ 超出改判为假象（I065/B020）——v18 保存的 flux 本就是每 arcmin²，旧 flux/area 双重归一；图与文字全部更正。Q-A 试点结果（无策略认证，T153）、Q-B 搁置与逐仪器路线（D46）、GTI 保留 2.filter（I066）、mask 规则 v2 与"残余必须建模"（E035）、Virgo 再抽谱计划（D47）入表。新增开问题：MOS1 静态硬过剩。
- 2026-10-15 (stage-2 revision): the Q-C 13′ excess is reclassified as an artefact (I065/B020) — the v18 saved flux was already per arcmin², so the old flux/area double-normalised; figure and text corrected throughout. The Q-A pilot result (no strategy certified, T153), the Q-B parking and per-instrument route (D46), keeping GTI 2.filter (I066), mask rule v2 with "the residual must be modelled" (E035), and the Virgo re-reduction plan (D47) entered the tables. New open problem: the MOS1 quiescent hard excess.
- 2026-10-15：手册首次构建（H-XART-001）；PI 新增四问（Q-A…Q-D），四个研究 job 派出。
- 2026-10-15: first handbook build (H-XART-001); the PI added four questions (Q-A…Q-D) and four research jobs were dispatched.
- 2026-07-15：D45 — P0 反馈检验 NO-GO（full-nuisance 区间过零），P1 停止。
- 2026-07-15: D45 — P0 feedback test NO-GO (full-nuisance interval crosses zero); P1 stopped.
- 2026-10-05/06：Chandra+XMM 联合管线停在 8/20 PASS。
