name: Coverage Report (Non-gating)

# Generates coverage reports with broad instrumentation (src/**/*.{ts,tsx})
# but does NOT gate on test pass/fail. Allows monitoring coverage expansion
# progress without blocking PRs on V8/vi.mock() incompatibilities (see #19998).

    # #23490 — broad coverage instrumentation over all of src/**/*.{ts,tsx} is
    # slower than the narrower "gate subset" run. 40 min was no longer enough
    # headroom either (100/100 runs cancelled 2026-09-23..2026-10-07, each
    # hitting the ceiling mid-suite before the non-gating summary was produced).
    # If the suite keeps growing, shard this run like coverage-hourly.yml
    # (TOTAL_SHARDS) instead of raising this further.
