+
+Verified arXiv:2602.20889v2 and arXiv:2607.08576v1 and added canonical
+bibliography entries `Li2026Jackpot` and `Li2026WFI2033`. Added concise claim

+H0 inference, which does not yield a robust standalone constraint. No PDFs
+were stored in the repository.

+## 2026-10-11 — DSPL references for the Euclid manuscript
+
+- Added missing canonical entries `Sahu2025DSPL` (ApJ 991, 72) and `EuclidQ1DSPL` (A&A 711, A29), checking DOI, arXiv ID, and title for duplicates.
+- Added compact support and scope notes in `sources/gr-cosmology.md`, distinguishing the AGEL cosmography measurement from the Euclid Q1 candidate-discovery and modelling study.
+- Verified against arXiv:2504.00656, arXiv:2503.15327, and their published records. Author confirmed that “Sheu” meant Sahu and that the Li reference was the Euclid Q1 paper.

+
+**Canonical BibTeX key:** `Li2026Jackpot`
+**Reference:** Li et al. 2026, MNRAS 548, stag683; doi:10.1093/mnras/stag683; arXiv:2602.20889 (v2).
+**Concepts:** [[bulge-halo-decomposition]], [[mass-sheet-degeneracy]], [[mass-models]]
+
+**Supports:**
+- Models J0946+1006 using MGE-traced stellar mass, allowing a radial mass-to-light gradient, plus a generalised NFW dark halo.
+- The two source planes provide additional constraints on radial structure and mass-sheet freedom.
+- Within the tested models, the preferred stellar normalisation is Salpeter-like, with an approximately constant mass-to-light ratio and an NFW-compatible inner halo slope.
+
+**Use when:**
+- Citing a recent composite mass analysis of a double-source-plane lens or motivating stellar–dark-matter decomposition with Euclid lenses.
+
+**Do not use for:**
+- A universal IMF or halo-profile conclusion for all ellipticals, or a model-independent removal of every mass-sheet degeneracy.

+**Reference:** ApJ, 991, 72; https://doi.org/10.3847/1538-4357/adf442; https://arxiv.org/abs/2504.00656
+**Concepts:** [[lens-equation]], [[mass-sheet-degeneracy]]
+
+**Supports:**
+- Modelling AGEL150745+052256 with HST imaging and Keck spectroscopy constrains a cosmological distance ratio sensitive to matter density and dark energy.
+- Combining this system with the Jackpot lens and CMB measurements demonstrates complementarity between DSPL cosmography and other cosmological probes.
+
+**Use when:**
+- Citing an observed galaxy-scale DSPL cosmography measurement beyond Collett and Auger's Jackpot analysis.
+
+**Do not use for:**

+**Concepts:** [[euclid-q1]], [[lens-finding]], [[lens-equation]]
+
+**Supports:**
+- Euclid Q1 yielded four new galaxy-scale DSPL candidates, with lens models estimating their cosmological scaling factors.
+- The study motivates larger DSPL samples as probes of galaxy structure and cosmological distance ratios.
+
+**Use when:**
+- Motivating Euclid's contribution to finding and modelling DSPLs for future cosmography.
+
+**Do not use for:**
+- A completed dark-energy measurement from these four candidates or an assertion that every candidate is spectroscopically confirmed.

+**Reference:** Li et al. 2026, arXiv:2607.08576 (v1); doi:10.48550/arXiv.2607.08576.
+**Concepts:** [[bulge-halo-decomposition]], [[time-delay-cosmography]], [[mass-sheet-degeneracy]]
+
+**Supports:**
+- Uses JWST/NIRCam imaging and measured quasar time delays to fit MGE-traced stellar mass with a free radial mass-to-light gradient plus a generalised NFW halo.
+- Tests two external cosmological priors; within each, time delays restrict mass-sheet freedom and allow the stellar and dark components to be separated.
+- Explores cosmological inference without stellar kinematics, but finds that the H0–halo-scale-radius degeneracy prevents a robust standalone H0 constraint.
+
+**Use when:**
+- Discussing composite lens models for time-delay lenses, their cosmological dependence, or the need for additional information in H0 inference.
+
+**Do not use for:**
