+# Code Coverage Contract
+
+Code coverage is execution evidence: it shows which instrumented code ran during a test run. It does not prove behavior is correct, tests assert the right outcomes, or UI and device paths are adequately verified.
+
+## Default Policy
+
+- Report coverage by target and file, and include function-level detail when the tool provides it.
+- Keep test failures, coverage-collection failures, and missing-report failures as separate results.
+- Default to reporting only. Do not invent a global coverage percentage, fail a build, exclude a source path, or claim changed-line coverage without an explicit repository policy.
+- Treat generated, vendored, test-target, and platform-glue sources as visible in the first report. Exclude them only with a checked-in, human-readable reason.
+- Do not commit generated coverage reports by default. Keep local reports ephemeral and upload CI reports only when that repository's CI policy asks for it.
+
+## Required Evidence Packet
+
+Every coverage result should state the toolchain and coverage command; configuration, scheme or package, and destination when applicable; report artifact path and format; target and file summary; exclusions and their reason; whether the result is comparable with a baseline; and test, collection, and report-extraction failures independently.
+
+## Comparison And Gates
+
+Compare coverage only when the source revision, toolchain, build configuration, selected targets, destination, and exclusion policy are compatible. A raw project-wide percentage is not a substitute for changed-file or changed-line evidence.
+
+Add a CI gate only after the repository chooses one concrete metric: an overall minimum, target minimum, changed-file minimum, or changed-line minimum. Record the policy and allowed exceptions in the repository; keep the Apple Dev Skills default report-only.

+# SwiftPM Code Coverage
+
+Use SwiftPM coverage for a package-first test surface. Follow the shared [`code-coverage-contract`](../../../shared/references/code-coverage-contract.md) for evidence, artifacts, comparisons, and gates.
+
+## Collection And Report Discovery
+
+Run coverage as part of the test command:
+
+```bash
+swift test --enable-code-coverage
+```
+
+After a successful collection, ask the active toolchain for the exported JSON location instead of hard-coding a `.build` path:
+
+```bash
+swift test --show-codecov-path
+```
+
+Treat `--show-codecov-path` as a separate report-location query. Do not assume every SwiftPM release accepts it combined with `--enable-code-coverage`, and do not split coverage into a separate build plus `swift test --skip-build` path unless that exact toolchain has been verified.
+
+## Reporting
+
+Read the exported JSON from the reported path and summarize the targets and files it contains. Preserve the original artifact path in the evidence packet. If the file is missing, unreadable, or does not contain the expected coverage payload, report extraction failed; do not substitute a guessed `.build` location or a percentage inferred from test output.
+
+SwiftPM coverage is appropriate for package targets and their ordinary tests. It does not replace app-host, XCUITest, simulator, physical-device, or Xcode test-plan coverage. Hand off to `xcode-testing-workflow` when those surfaces matter.
+
+## Failure Boundaries
+
+- A passing `swift test` without an exported coverage JSON is a coverage-collection failure, not a zero-coverage result.
+- Keep package coverage reports out of version control unless the package has an explicit artifact policy.
+- Do not create a coverage gate without a repository-owned metric and exclusion policy.

+# Xcode Code Coverage
+
+Use Xcode coverage for Xcode-managed test targets, UI tests, app-hosted tests, simulator or device destinations, and `.xctestplan` configurations. Follow the shared [`code-coverage-contract`](../../../shared/references/code-coverage-contract.md) for evidence, artifacts, comparisons, and gates.
+
+## Collection
+
+For an explicit CLI run, use a real project or workspace, scheme, and destination. Capture an `.xcresult` bundle so the coverage data is inspectable after the test process exits:
+
+```bash
+xcodebuild test -workspace <workspace>.xcworkspace -scheme <scheme> \
+  -destination '<destination>' -enableCodeCoverage YES \
+  -resultBundlePath <artifacts>/<run>.xcresult
+```
+
+Replace `-workspace` with `-project <project>.xcodeproj` only when the project is not workspace-managed. For repeatable named configurations, version an `.xctestplan` that enables coverage and run it with `-testPlan <plan>`; do not use a plan merely to hide an otherwise simple one-off coverage command.
+
+## Reporting
+
+Use `xccov` against the result bundle rather than scraping test logs:
+
+```bash
+xcrun xccov view --report --json <artifacts>/<run>.xcresult
+xcrun xccov view --archive --json <artifacts>/<run>.xcresult
+```
+
+The report gives target, file, and function coverage. The archive provides execution-count detail. Use `xcrun xccov diff --json <before>.xcresult <after>.xcresult` only when the two runs meet the shared comparison contract.
+
+## Xcode 27 MCP Boundary
+
+Xcode 27 beta documents new MCP capabilities for active run-state control, debugger-console interaction, scheme and run-destination management, build-setting/compiler-flag/entitlement/Info.plist inspection and mutation, runtime health insights, simulator interaction, preview variants, and String Catalog workflows. Discover the tool inventory from the live Xcode session before naming or invoking a specific tool.
+
+Apple does not document a coverage-report MCP tool in this beta. Use Xcode MCP for session discovery and test execution when the live session provides those tools, then use `xcodebuild` and `xccov` for deterministic coverage collection and report extraction.
+
+## Failure Boundaries
+
+- A successful test run without an `.xcresult` or readable `xccov` report is a coverage-collection failure, not a coverage result.
+- A coverage report with failing tests remains a failing test run; do not report its percentage as a passing quality signal.
+- Do not compare simulator and physical-device coverage, Debug and Release coverage, or different schemes as though they are the same baseline.
