codecov.yml

# Codecov — the primary PR coverage gate (replaces the fixed absolute-% pin that
# vitest.config.mjs used to enforce; those thresholds are now just a backstop
# floor). This is DELTA-based, so it never causes the "every PR must match a
# near-peak absolute number and one merge pushes the others below it" churn:
#   - `project` compares total coverage to the PR base, tolerating a small drop.
#   - `patch` checks only the lines THIS PR changed (the real "test your new
#     code" signal — PR-local, independent of global fluctuation).
# The uploaded lcov is already scoped to runtime code (src/** + workers/** + 5
# named scripts) by vitest's coverage.include, so Codecov reports only those.

# Codecov's own status checks are only merge-blocking if added to branch
# protection's required checks (metagraphed's are intentionally empty — the owner
# admin-merges). Until then these are informative PR annotations + the dashboard.
