Hi maintainers,

I run the JS/TS Coverage Index at TaskBounty and currently show h3js/h3 at 78%:

https://www.task-bounty.com/coverage-check/h3js/h3

Coverage is a map, not a grade, so I do not want to imply the number says anything final about quality. I’m sharing this because there may be a small opportunity to improve confidence in one focused area.

Would you be open to a small PR that adds behavior tests for one uncovered path?

Guardrails:

• no snapshot padding
• no mock-only assertions
• no threshold changes
• no excluded files
• existing tests stay green
• PR stays small enough to review

If this is not welcome, feel free to close this and I will not follow up. I do not want to create drive-by maintenance work.
