# Notebook source checks — 2026-09-23

The weekly notebooks reuse the existing local specifications, v6 chapters and resource cards. This is a targeted verification log, not a claim that every external card, paper, video or dataset was read or tested. Historical verification dates in the original materials remain unchanged.

| Source | Check and use |
|---|---|
| [Google source import guidance](https://support.google.com/notebooklm/answer/16215270?hl=en) | Official page retrieved. Text, Markdown and pasted text are supported source routes. Linked pages are not recursively imported; check the imported source content. Product/interface wording may differ from the programme’s NotebookLM name. |
| [OpenStax Calculus 5.1](https://openstax.org/books/calculus-volume-1/pages/5-1-approximating-areas) | Official section retrieved; optional foundation repair for accumulation and area approximations. The notebook’s pump and biomass examples are original teaching examples, not research results. |
| [SciPy solve_ivp](https://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.solve_ivp.html) | Official API page retrieved. Use the documented function interface and examples with your installed version; the plan’s particular predator–prey example may differ by documentation version. |
| [scikit-learn common pitfalls](https://scikit-learn.org/stable/common_pitfalls.html) | Official guide retrieved; supports the preprocessing/leakage checks. No installed-version compatibility or project experiments were tested by browsing it. |
| [Conformal prediction tutorial](https://arxiv.org/abs/2107.07511) | Primary paper record retrieved. Use sections 1–2 and verify the applicable calibration rule and assumptions before implementing; shifted-data coverage is not assumed. |
| [FLIP author repository](https://github.com/J-SNACKKB/FLIP) | Verified working author repository via the [original FLIP paper](https://www.biorxiv.org/content/10.1101/2021.11.09.467890v2). The inherited `github.com/J-SN/FLIP` returned 404. New notebooks use the corrected locator where that URL occurred. Existing master plans/cards remain preserved. Inspect task-specific split guidance before comparing scores. |
| [Europe PMC API documentation](https://europepmc.org/RestfulWebService) | Main documentation request returned 403 in the browsing tool. The [provider’s development documentation](https://dev.europepmc.org/RestfulWebService) was readable and points to the [official EBI search endpoint](https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=p53). Do not assume the development site is a production data source; verify current production access when executing. |
| [statsmodels mixed effects](https://www.statsmodels.org/stable/mixed_linear.html) | Official documentation retrieved. Consult model assumptions and examples for the specific field-trial design. This does not validate a future analysis. |
| [Zhang, Chung and Oldenburg 1999](https://journals.sagepub.com/doi/10.1177/108705719900400206) | Primary publisher record located; [Broad-hosted paper PDF](https://data.broadinstitute.org/bbbc/linked_files/Zhang_JBiomolScr_1999.pdf) accessible. Reference for Z-prime/control separation, not a universal assay acceptance policy. |
| [arXiv endorsement](https://info.arxiv.org/help/endorsement.html) | Official guidance retrieved. Recheck category eligibility at execution; endorsement, moderation and peer review are distinct. |
| [JOSS submissions](https://joss.readthedocs.io/en/latest/submitting.html) | Official guidance retrieved. Eligibility and submission requirements must be checked again against the actual software at Week 36. |

The original weekly plans already correct several aspirational master-plan statements. The notebooks retain those corrections: IndPenSim is simulated; lag requires an explicit mechanism; DO alone may not identify kLa; exact SINDy recovery is not guaranteed; computational rankings are not wet-lab validation; external events need actual evidence.

For an inaccessible source, record the title, attempted URL, access date and the exact gap. Use a free primary-source substitute addressing the same concept, or keep the relevant task pending. Never describe a search link as an inspected source or fabricate an exact video timestamp.
