WHAT IS IN THE ARCHIVE

   The_Price_Duration_Curve.xlsx      Chapters 2 and 5
   The_Plant_Four_Ways.xlsx           Chapters 4 to 7 and 10

   00_START_HERE.md                   what changed is at the end
   Each workbook closes on a checks sheet: 152 checks, ALL OK.

2. Blank_Model_Set/  (new)
   The four workbooks with every blue input emptied, for your own curve,
   plant, customers and documentation. Each checks sheet counts what is
   still missing and tests what holds for any inputs. The book's figures
   are in book_inputs.txt: type them back in and the book's results come back.

3. Working_Documents.pdf  (new)
   Thirteen printable pages: the position report interrogated, the curve on
   one page, marginal cost and the spark spread, dispatch and concentration,
   the plant valuation four ways, the outage plan as a valuation, the retail
   hedge proposal, the true short reconciled, two legs and two clocks,
   liquidity as a position limit, the group on four cells, the report that
   would survive, and the one page with Monday's four tasks. A4, fits Letter.

4. Forty_Questions.xlsx  (new)
   Forty questions across the book, marked by the file as you type.

5. Cases/  (new)
   Case_1_The_Gas_Leg_Nobody_Counts.xlsx        Chapters 4 and 10
   Case_2_Three_Dates_The_Diary_Allows.xlsx     Chapters 7 and 15
   Case_3_The_Three_Reliefs_Priced.xlsx         Chapters 13 and 14
   Each case: the note on the first sheet, the model after it, checks at the end.
