Feature / Fix ComponentResolution Details
Leap Year Verification (#2094)Added an isolated unit test block to lib/calculate.test.ts that specifically simulates a leap-year calendar setup, ensures boundary dates process correctly using mock time variables, and asserts that longestStreak and currentStreak evaluate accurately.

Core Logic Stability: Ensured that calendar generation logic handles the shift across February 28th, February 29th, and March 1st without breaking contribution streak arrays.
Boundary Math: Validated that leap day offsets do not result in index evaluation bugs or miscalculations during streak array parsing.

Difficulty — intermediate: Large PR touching 80+ files across API routes, middleware, tests, types, and library code. The scope includes leap year validation fixes, API security improvements, studio copy actions, and major type definition changes (WrappedStats.totalContributions from number to RepoContribution[]). This breadth makes it intermediate despite individual changes being simple.

Type — bug + security + refactor: Leap year validation fixes (bug), security improvements in API routes (security), type definition corrections (refactor).

⚠️ This PR is currently blocked (status:blocked label — failing CI checks). Cannot approve a blocked PR. The changes themselves look reasonable, but this needs passing CI before it can be merged. Please address the CI failures and rebase, then I'll be happy to re-review.

Keep at it — the scope of changes here shows solid understanding of the codebase! 💪

The title mentions 'leap year validation, API security, and studio copy actions' but the changes are much broader. This appears to be a duplicate or overlap with #5850.
