    "rationale": "Matched 1:1 biweekly cadence, following the ASTR230/ASTR310/ASTR320/ASTR340 precedent (a 3-credit, 14-lecture structure), because ASTR350's seven thematic units are each exactly two lectures long (unlike ASTR320's variable 2-3 lecture units), so a strict two-lecture-per-lab grid is the natural, unambiguous cadence. See syllabus.html Lecture, Lab, and Problem-Set Cadence."

      "51 Pegasi b and HD 209458 b system parameters - live-verified via direct web fetch this session (Wikipedia, 2026-09-24), citing Mayor & Queloz (1995) and Charbonneau et al. (2000)/Henry et al. (2000). A units error in the fetched 51 Pegasi b infobox (K given as km/s instead of m/s) was caught by cross-checking against the article's own prose and the published literature value, and corrected before use.",
      "TRAPPIST-1 seven-planet system - reused and extended from this curriculum's ASTR320 course, where it was live-verified via direct web fetch (Wikipedia, 2026-09-24), citing Agol et al. (2021), Ducrot et al. (2020), Gillon et al. (2017), and Delrez et al. (2022). Per-planet mass/radius values are standard published (Agol et al. 2021), consistent with the range already established in ASTR320.",
      "HD 80606 b and 16 Cygni B b (eccentric RV planets); extremophile survival/growth records; Miller-Urey relative amino-acid abundance ranking; Kasting-Whitmire-Reynolds (1993) habitable-zone flux boundaries - standard published primary literature, not independently re-verified this session, flagged for spot-check in reference-log.md.",
      "Drake equation biological terms (f_l, f_i, f_c, L) - explicitly labeled illustrative/synthetic order-of-magnitude placeholders, not claimed measurements."
