Coverage uploads have been failing since 2026-09-12. Codecov's newest data is commit e6922b5; everything merged since — including #213 and #214 — never reached it. That is why the badge still reads 69% after the selector fix.

From the most recent run's log:

['error'] There was an error running the uploader: Error uploading to https://codecov.io:
429 - {"message":"Rate limit reached. Please upload with the Codecov repository upload
token to resolve issue. Expected time to availability: 1291s."}

['info'] Codecov will exit with status code 0.

Two separate problems:

Tokenless uploads from public repos are rate limited. Codecov's own message names the fix: use a repository upload token.

The failure was invisible. codecov-action exits 0 on upload errors, so the job showed a green tick while the badge quietly went stale for two days and several merges.

Change

with:
  token: ${{ secrets.CODECOV_TOKEN }}
  fail_ci_if_error: true

fail_ci_if_error matters as much as the token — without it the next upload problem is equally silent.

CODECOV_TOKEN is already set on the repo.

Expected effect

The badge should move from 69% to ~82% on the first successful upload from main, reflecting the 175 tests #214 brought into the job.

Not addressed here

codecov-action is on v3 while v5 is current, and the run warns that actions/cache@v3, actions/checkout@v2 and actions/setup-java@v2 are being forced onto Node 24 across all workflows. Worth a separate pass.
