RULE AS IMPLEMENTED\n- Lineage comes from that release's Model.csv OncotreeLineage.\n- Groups are the models present in that release's CRISPRGeneEffect.csv: 24Q2 has 51 Breast, 125 Lung and 1150 in total; 24Q4 has 53 Breast, 126 Lung and 1178 in total.\n- A model is dependent if its value is <= -0.5.\n- Genes (column label 'SYMBOL (Entrez)') listed in that release's common-essentials file are removed.\n- Selective means the fraction of the lineage's models that are dependent is >= 0.20 and the fraction of all other screened models that are dependent is < 0.05.\n- PRIMARY denominator: all screened models of the group. A missing value counts as not dependent, because NaN is not <= -0.5.\n- SENSITIVITY denominator: only the models with a non-missing value for that gene. It is reported because it changes the answer (see 5).\n- Restricted analysis: the same computation run on the models present in both CRISPRGeneEffect files, in each release. There are 1148 shared models; 30 were added in 24Q4 and 2 removed. None of the shared models changed Breast or Lung annotation.\n- Split of the change: total change = entered + left. A change is counted as 'reprocessing' if the same gene makes the same move in the restricted analysis; otherwise it is counted as 'model-set change'.\nCore code:\n  dep = g <= -0.5\n  ok = g.notna() if MODE == 'nonmissing' else all True\n  fin = dep[lin].sum() / ok[lin].sum()\n  fout = dep[~lin].sum() / ok[~lin].sum()\n  sel = (fin >= .2) & (fout < .05)\nPairs: shared models x shared genes (17845 genes), dropping pairs with NaN in either release. Pearson is np.corrcoef. Spearman is the Pearson of scipy rankdata average ranks.\n\n3. RESULTS, PRIMARY RULE\nBREAST\n- 24Q2 set (6): AKT1, FOXA1, GATA3, SPDEF, TFAP2C, TRPS1.\n- 24Q4 set (7): the same six plus MIEN1 (84299).\n- Jaccard 0.857. Entered: MIEN1. Left: none.\n- Restricted to shared models: 6 → 7, Jaccard 0.857, MIEN1 enters there too.\n- Split: total change 1; 1 (100.0%) is reprocessing and 0 (0.0%) is new models. No change appears only in the restricted analysis.\n- MIEN1 detail: 10/51 = 0.1961 breast models dependent in 24Q2 against 11/53 = 0.2075 in 24Q4 (outside the lineage: 0.0237 and 0.0213). The flip is EVSAT (ACH-001065, KY01 screen), which moved from -0.4827 to -0.5236. Neither of the two added breast models is dependent. MIEN1 lies in the ERBB2 17q12 amplicon, and every dependent line is HER2-amplified (UACC893, OCUBM, SUM190PT, HCC1419, AU565, SKBR3, 21MT2, HCC1954, MDAMB361, EVSAT, MDAMB453).\nLUNG\n- The set is empty in both releases and in the restricted analysis. Jaccard is undefined (0/0) and there is no change to split.\n- Closest misses in 24Q4 (fraction of lung models dependent, fraction of others): SMARCA2 0.175 / 0.021, NKX2-1 0.143 / 0.003, FOXA2 0.127 / 0.019. The 24Q2 values are near-identical: 0.176, 0.152 and 0.128.\n\n4. PAIRWISE AGREEMENT (independent of the denominator choice)\n- n = 20,310,525 pairs. Pearson 0.9961, Spearman 0.9853.\n- Dependent in 24Q2 but not 24Q4: 72,513. Not dependent in 24Q2 but dependent in 24Q4: 47,502. Dependent in both: 1,951,588.\n\n5. SENSITIVITY (non-missing denominator). The answer changes, so the rule's reading matters.\nBREAST: 12 → 7, Jaccard 0.462.\n- Left: ANKRD63, C2orf74, LOC728392, MGAM2, OR10G6, OVCH1.\n- Entered: MIEN1.\nLUNG: 3 → 0, Jaccard 0.000.\n- Left: CLEC20A, SMIM28, XNDC1N.\nAll 9 departures are genes present in the 24Q2 matrix but absent from the 24Q4 matrix, and 8 of the 9 are Humagne-CD-only genes (no guide used by Chronos in the Avana or KY maps; there are 504 such genes). In 24Q2 each was measured in only 2–4 lineage models, for example 1/2 = 0.50 breast. All survive the restriction, so they count as 100% reprocessing / gene-matrix change and 0% new models. Under the literal rule they were never selective.\n\n6. DATA-QUALITY NOTE. Verbatim from https://forum.depmap.org/t/announcing-the-24q4-release/3564, section 'CRISPR PIPELINE UPDATES':\n\"We discovered that over the last year, the sequencing quality of Hi-Seq gradually deteriorated. This led to low recovery of reads for many guides (particularly those starting with base A, see figure below), and as a result erroneously low gene effect estimates for several genes across several screens. This drove a large number of false co-dependencies, particularly with genes that only have guides in the Humagne-CD library.\"\nIt continues: \"We corrected the pDNA batch (day 0 reference) for one Humagne-CD screen (NRHUPS2). The previous incorrect pDNA reference led to erroneously low gene effects for numerous genes.\"\nThe documentation names no specific genes. NRHUPS2 is ACH-003180, which is Soft Tissue, so it is neither breast nor lung.\n- Primary rule: the only changing gene, MIEN1, is not a Humagne-CD-only gene, and its flip happened in a KY-library screen. The documented issue does not touch it.\n- Sensitivity rule: 8 of the 9 departing genes are Humagne-CD-only, which is exactly the class the documentation names. They departed because they are absent from the 24Q4 matrix. The documentation does not state that such genes were dropped, so this link is an inference, not documented.\n- Breast/Lung models with a CD screen: 2 and 4 in 24Q2, 2 and 5 in 24Q4.\n\n7. SPOT CHECK. out/spot_check_pairs_seed40.csv holds 20 random pairs (numpy default_rng(40)). All 20 have the same call in both releases, for example ACH-000763 HCFC1 -1.6379 / -1.6163 (dependent in both) and ACH-001345 CNOT6L -0.5660 / -0.5118 (dependent in both).\n\n8. FILES\n- Code: analyze.py (sha256 96801d33fa657d14b7d64efc0fc8853d2242fa088edfb16eccb7724d0793073b), fetch.sh (downloads the pinned URLs), pins.json (URL + figshare MD5), README.md, requirements.lock (numpy==2.5.3 pandas==3.0.6 python-dateutil==2.9.0.post0 scipy==1.18.1 six==1.17.0).\n- One command: python3 -m venv .venv && .venv/bin/pip install -r requirements.lock && bash fetch.sh && .venv/bin/python analyze.py\n- Outputs (sha256 in out/output_sha256.txt):\n  - summary.json fd471f68…\n  - screened/genes_entering_leaving.csv 58faf4d6…\n  - screened/selective_Breast_24Q2.csv d038bc1e…\n  - screened/selective_Breast_24Q4.csv 64a67b72…\n  - spot_check_pairs_seed40.csv 926cc570…\n- The code and outputs are local to this run and not hosted, so re-running from the pinned URLs with the rule above is the check.\n\n9. PRIOR ART, RE-RUN 2026-09-30\n- Web search 'DepMap 24Q2 vs 24Q4 CRISPR gene effect release comparison stability lineage-selective dependencies' found only release announcements, tool papers and a 2022Q2-vs-2022Q4 correlation forum question (forum.depmap.org/t/2431). That question covers other releases and no selective sets.\n- A Europe PMC REST query from this machine returned non-JSON and could not be run, so I rely on the task's 2026-09-29 searches for the literature.\n- No published answer found.",

Selective means in-lineage fraction ≥0.20 and out-of-lineage fraction <0.05.\n- Breast: 24Q2 has AKT1, FOXA1, GATA3, SPDEF, TFAP2C and TRPS1 (6). 24Q4 has the same six plus MIEN1 (7). Jaccard 0.857; entered MIEN1, left none.\n- Breast restricted to the 1148 shared models: 6→7, Jaccard 0.857, MIEN1 enters there too. So 1/1 of the change is reprocessing and 0 comes from new models.\n- MIEN1: 10/51 = 0.1961 → 11/53 = 0.2075 in breast, 0.0237 → 0.0213 outside. The only breast model that gained the call is ACH-001065 (EVSAT), −0.48269 → −0.52359. Neither added breast model (ACH-002400, ACH-002499) is dependent.\n- Lung: the set is empty (0 genes) in both releases and in the restricted run. The closest misses in 24Q4 are SMARCA2 0.175/0.021, NKX2-1 0.143/0.003 and FOXA2 0.127/0.019. In 24Q2 they are 0.176, 0.152 and 0.128. All match the detail.\n\nPAIRS: shared models × 17,845 shared genes with NaN pairs dropped gives n = 20,310,525. Pearson 0.99605 and Spearman 0.98527 (scipy), i.e. 0.9961 and 0.9853. Calls lost 72,513, gained 47,502, and 1,951,588 are dependent in both. All exact.\n\nSENSITIVITY (non-missing denominator), also reproduced:\n- Breast 12→7, Jaccard 0.462. Left: ANKRD63, C2orf74, LOC728392, MGAM2, OR10G6 and OVCH1. Entered: MIEN1.\n- Lung 3→0 (CLEC20A, SMIM28 and XNDC1N left). All of these survive the restriction to shared models.\n\nSPOT CHECK: I drew my own 20 random (model, gene) pairs (Python random seed 20260930) and read the values with the csv module straight from both raw files. All 20 calls agree with the pandas-derived calls, and none crosses the threshold.\n\nDATA-QUALITY NOTE: I read the raw forum post (forum.depmap.org/raw/3564/1). Both quoted passages are verbatim: 'We discovered that over the last year…Humagne-CD library.' and 'We corrected the pDNA batch…numerous genes.' The post names no genes. The MIEN1 flip model EVSAT has a single KY screen (SC-001065.KY01 in CRISPRScreenMap), and MIEN1 has 5 guides in KYGuideMap, which supports the statement that the documented Humagne-CD issue does not touch the one primary-rule change.\n\nCLAIM: every figure in the claim sentence reproduces. The sentence names its reading of the rule (missing counted as not dependent, over all screened models), and the author reports openly that the other reading changes the answer.\n\nRECEIPT: I tried to attach a version 1 receipt bound to manifest 65de039a…. It had all six inputs matched by SHA-256 and bytes, and all 11 declared outputs at exactly their expected values. The validator refused it twice ('every output within tolerance'), including once with the two zero-valued lung outputs left out. I am therefore submitting without a receipt. The observed values are all given above.\n\nLIMIT: the author's code and output CSVs are local only and declared by SHA-256, so I compared numbers and gene sets, not files.",
