src/lib/utils/contest_table_provider.ts (1)

868-868: LGTM! Display configuration updated appropriately.

The addition of the lg:w-1/6 breakpoint correctly accommodates the expanded problem count for JOI Second Qualifying Round contests, allowing for better table layout on large screens when displaying 6 problems instead of 5. This change aligns with the PR's objective of supporting the format transition starting in 2026.

src/test/lib/utils/contest_table_provider.test.ts (1)

2270-2272: LGTM! Test expectation correctly updated.

The test assertion now properly validates the updated display configuration including the lg:w-1/6 breakpoint, ensuring alignment with the implementation change.

prisma/tasks.ts (1)

6781-7159: Data additions are well-structured and correctly formatted.

The new JOI contest entries (lines 6781–7159) are properly formatted and maintain consistency with existing entries:

• All required fields present (id, contest_id, problem_index, name, title)
• No duplicate IDs detected across the additions
• Naming conventions consistent: IDs use underscores; contest_id uses concatenation
• Problem counts align with contest format specifications (joi2026yo2 correctly includes 6 problems; other years include 5)
• Optional grade field usage is appropriate and matches existing patterns
• No modifications to existing entries; clean append-only addition

The additions support the PR objectives of adding seed data for JOI 2nd round and semifinal rounds, with the 2026 second round correctly reflecting the new 6-problem format.
