Sol-Mod — open documentation questions

From the CoolSky Buildings iterations document (Ch. 5: Sol-Mod House):

1. Build year — Stated as “undated.” When was it built?
2. Location, owner, occupancy — Not documented in the KB.
3. Photographer — Who took the c. 2017 exterior photos?
4. Heating performance — Are there min/max temperature logs?
5. Materials and drawings — Is there a drawing set, take-off, or cost record? (See also solmod-pipe-material.md for the pipe material question.)
6. Summer drain cycle — Does the drainable array actually drain and refill for summer cooling?
7. Davis House 3 relationship — Is Davis House 3 the same building as the Sol-Mod, or a separate installation?
8. Photo count — Two images in the article vs. more in the gallery — which set is authoritative?

Also from the appendix — Dave House North: identity and date (2008–09 vs. 2009) are unclear. The iterations document marks this as the “top question for Jose/Bruce.”

Next action: Jose and Bruce for build history (#1–2, #7, appendix item); Bruce for the summer drain cycle (#6); photographer and materials questions may need archive research.
