<think>I need to solve this advanced book portfolio analysis problem. Let me break this down into phases:

PHASE 1 - Database Setup:
1. Load JSON data files (books.json and book_prices.json)
2. Create SQLite database at /workdir/books.db
3. Create appropriate tables and load data
4. Ensure proper relationships and indexing

PHASE 2 - Complex Portfolio Query:
I need to find 8 books that meet all these constraints:

- Total cost between $115.00-$120.00
- No book > $25.00
- No book < $5.00
- Most expensive book >= $15.00
- Price variance < $12.00

TEMPORAL CONSTRAINTS:
- Exactly 3 books after 1990
- Exactly 3 books 1960-1990 (inclusive)
- Exactly 2 books before 1960
- Span at least 6 different decades
- No more than 2 books from same decade

DIVERSITY CONSTRAINTS:
- All 8 authors different
- At least 5 different genres
- No more than 2 books from any single genre
- At least 2 books with numbers in title
- Exactly 1 book from "Horror" genre

CONTENT CONSTRAINTS:
- Combined pages between 2800-3600
- At least 3 books > 400 pages
- No book < 150 pages
- Ordered by publication year (oldest to newest)
- Save as CSV with specific format

Let me start by exploring the data and setting up the database.</think>

<think>Now I understand the data structure. Both files contain JSON arrays:
- books.json: contains books with title, author, year, genre, pages
- book_prices.json: contains book prices with title and price

I need to create a database that combines these two datasets and then solve the complex portfolio problem. Let me start by setting up the database.

I'll need to:
1. Create SQLite database at /workdir/books.db
2. Create tables for books and prices
3. Load the data from JSON files
4. Create relationships and indexes
5. Write complex queries to find the 8 books that meet all constraints

Let me start by creating the database and loading the data.</think>
