Completes the crash-interrupted #192 WIP (app/build.gradle.kts already had a
jacocoTestReport task and toolVersion pin recovered onto build-192-jacoco):
- Move the JaCoCo tool version into gradle/libs.versions.toml instead of a
hardcoded string in app/build.gradle.kts, matching how every other plugin
version in this repo is sourced.
- Fix the generated-code exclusion list against the real compileDebugKotlin
output (verified by inspecting the compiled class tree): Room's
KSP-generated `_Impl` DAOs/database and the Compose compiler's per-file
ComposableSingletons holders are the only generated code that actually
lands in classDirectories, since Hilt/Dagger's generated Java and AGP's
BuildConfig/R/Manifest are compiled by a separate javac task this report
never reads. Drop the blanket `**/*$$*` exclude the WIP had — it was
silently discarding ~200 real classes' worth of coverage on Kotlin's own
`$$inlined$` synthetic classes (e.g. Flow.map { ... } transforms in the
repositories), which is hand-written logic, not generated boilerplate.
- Add Hilt_*/Dagger* prefix patterns so the (currently inert,
belt-and-suspenders) Hilt exclusions are actually correct if the
classDirectories scope ever changes.
- Add a minimal CI step to the existing unit-tests job that runs
jacocoTestReport and uploads the XML+HTML report as a build artifact.
No coverage threshold gate yet (a jacocoTestCoverageVerification rule is
a natural follow-up once there's a baseline).
- Document the new :app:jacocoTestReport task in CLAUDE.md.
Verified on JDK 21: fast gate (assembleDebug, testDebugUnitTest,
compileDebugAndroidTestKotlin, lintDebug, ktlintCheck, detekt) plus
jacocoTestReport all pass, from both a warm and a `clean` build. The
report shows real signal (30% instruction / 38% line coverage) with no
generated classes leaking in.

assembleDebug, testDebugUnitTest, and lintDebug never compile the
androidTest source set, so a change that breaks it (e.g. an
instrumented test calling a UI API that just changed signature) passed
preflight locally yet only failed once CI ran. Add
:app:compileDebugAndroidTestKotlin to the fast gate to catch that
class of breakage before pushing, and update CLAUDE.md's summary of
the gate to match.

CI's "Static analysis" job runs :app:ktlintCheck :app:detekt, which the
local preflight gate did not, so style violations in test/androidTest
source sets (which lintDebug skips) failed the merge gate only after
push. Add both to the /preflight skill and mirror the change in CLAUDE.md.

- CLAUDE.md: build gotchas (JDK 17-21, AGP built-in Kotlin, KSP-not-KAPT),
test stack, the SPDX header rule, Conventional Commits, and commands.
- .claude/settings.json + hooks/check-spdx.py: PostToolUse hook that warns
(non-blocking) when a .kt/.kts file lacks the SPDX license header.
- .claude/skills/preflight: runs the fast CI gate (assembleDebug +
testDebugUnitTest + lintDebug) locally.
