codecov.yml

# Codecov configuration for the PIM sync engine — the SINGLE SOURCE OF TRUTH for the
# coverage thresholds.
#
# - `coverage.status.project.default.target` (below) is the whole-repo line-coverage
#   floor. The CI "Code coverage" job reads THIS value with `yq` and passes it to
#   `cargo llvm-cov report --fail-under-lines` (see .github/workflows/ci.yml), and the
#   local pre-PR check does the same (AGENTS.md), so the number lives in exactly one
#   place. Codecov also enforces it as the `project` status.
# - `coverage.status.patch.default.target` is enforced by Codecov only (the native
#   `cargo llvm-cov` has no per-diff metric). It is looser than `project` because the
#   provider crates have a thin HTTP/TLS boundary whose raw dial glue is only reachable
#   against a live server (covered by the gated `stalwart` job, excluded from the
#   offline metric); a strict patch target would red-X a small diff on that plumbing.
#
# Real coverage sits ~96–97%; these targets are the floor, not the aim.

coverage:
  # Round displayed percentages to two decimals, like the CI summary.
  precision: 2
  round: down
  status:
    project:
      default:
        # Whole-repo line-coverage floor. Read by the CI native gate + the local
        # pre-PR check; also enforced here by Codecov. Must not drop >1% vs. base.
        target: 95%
        threshold: 1%
    patch:
      default:
        # New/changed lines target (Codecov-only). Looser than `project` so a handful
        # of live-only transport lines in a small diff do not turn the PR red.
        target: 90%
        threshold: 1%

# Mirror the CI metric's test-support exclusions: the live/integration test files and
# the Stalwart harness are exercised in the `stalwart` job, not the offline coverage
# run, so counting them here would understate real coverage.
