"""Session 75: Type-6 Generic Tools + Catholic Reading Plan + Canon Enumeration.

Three scenarios from Cycle 2 architects:

  Scenario 1 — Type-6 Generic Tool Verification
    list_tools(), browse_tool(), get_tool_section() from accordance_mcp_server.
    Verifies module count, section markers, out-of-bounds handling, Unicode.

  Scenario 2 — Catholic Reading Plan Integrity
    daily_reading_plan("catholic") from accordance_mcp_server.
    Verifies plan structure, day count, deuterocanonical ordering, error paths.

  Scenario 3 — Catholic Canon Enumeration
    get_book_list(), get_chapter_list() from accordance_services.tools.text
    plus last_verse_of_chapter() from accordance_parser.canon.
    Verifies book counts, verse totals, chapter counts, boundary edges.
