# Codecov config. Coverage is REPORTED here for visibility (PR comment, trend
# graphs, per-crate breakdown). The REAL gate is the CI line floor in
# .github/workflows/ci.yml (the `coverage (>= 90% lines)` job runs
# `cargo llvm-cov --fail-under-lines 90`). The `project` status is
# informational (a nudge, never a block). `patch` is a real pass/fail traffic
# light on new-code coverage. Neither is a *required* check unless it is added
# to branch protection. Coverage uploads from ONE Linux cell, so flags,
# carryforward, and report-merging are not needed.
#
# Rust note: Codecov ingests the lcov that `cargo llvm-cov --lcov` emits
# directly; no cobertura conversion step is needed.
#
# Baseline: ~94% lines excluding src/main.rs (feed/selfcheck/ui/prober/
# chapters/index are all ≥98%; splitter is the lowest). src/main.rs is 0% (the
# live server wiring, not unit-testable) and is excluded from the report via
# `ignore` below.

# tests. It cannot be meaningfully unit-tested, so it is excluded from the

# line floor still measures the full tree; it carries enough headroom to
# absorb this ~0.8% of lines.)

# IMPORTANT: paths are EXPLICIT FILES, not `crates/<x>/**` globs. Codecov's
# component matcher silently does NOT pick up a `**` glob here (the component
# renders empty even at 100% coverage), whereas explicit file paths DO match.
# (Same quirk clauster's codecov.yml hit with its `db/**` / `hooks/**` components.)
# So when a crate gains a module, add its `.rs` file here; a glob would look
# fine and quietly track nothing.
