…alesce a save burst, classify the cheapest correct route Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
…ndness (Blocker) + MOVED_TO watch Blocker (SourceAnnotationScanner TYPE_DECLARATION): the declared-name regex captured "class" for Kotlin `enum class`, and had no branch for `typealias` or top-level `const val`, so edits to such anchor files classified as reload-safe and shipped stale generated code. Fixed the alternation (`enum\s+class` first) and added `typealias` + `const\s+val` branches; added the conservative backstop in AnnotationImpactAnalyzer (a declaration change in a file declaring no recognized name escalates while a processor is active). Covered by AnnotationImpactAnalyzerTest: "adding an entry to an enum class an entity stores escalates", "retargeting a typealias an entity column uses escalates", "bumping a top-level const the database version reads escalates", and "a declaration change in a file declaring no recognized name escalates". Important (AndroidProjectWatcher): directory MOVED_TO never triggered watch registration, leaving a renamed/moved-in package inotify-blind for the session. The recursion gate now fires on CREATE or MOVED_TO; files inside the moved tree are supplied by the poll sweep. FileObserver glue is JVM-inert in this module (isReturnDefaultValues), so the gate carries a precise comment rather than a faked test.

Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This change adds project watching and build-route classification, but current code can block the calling thread, leave file watches active after shutdown, and misclassify processor or annotation edits so generated code becomes stale.

Inline comments:
In `@quickbuild/core/build.gradle.kts`:
- Around line 32-40: Add a JacocoCoverageVerification task alongside
jacocoTestReport, using the v8Debug unit-test execution data and applying 0.90
minimum thresholds for both line and branch coverage. Make the existing CI
verification path depend on this verification task so the 90% gate is enforced
rather than only generating a report.
In `@quickbuild/core/README.md`:
- Around line 12-22: Update the ownership statements in the README to
distinguish app-owned implementations of Android capability ports from
Android-specific adapters that belong to quickbuild core, including
AndroidProjectWatcher and deploy services. Revise the repeated data-layer
ownership claim so it no longer implies all data implementations live in :app,
while preserving the domain layer’s Android-free contract.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/data/AndroidProjectWatcher.kt`:
- Around line 105-116: Guard registerCreatedTree against post-stop registration
by adding a stopped-state flag, checking it while holding the same observers
lock before creating or adding observers, and setting it during stop() before
clearing observers. If start() is reusable after stop(), reset the flag in
start().
- Around line 79-103: Move the filesystem walk, observer registration, and
restampSettled file-stat work in start into an IO-backed dispatcher instead of
the unconstrained scope. Ensure asynchronous registration remains
lifecycle-safe: track startup work, coordinate stop() with it, and prevent
cancellation during the non-suspending walk from leaving registered observers
untracked. Preserve the existing event collection and polling behavior.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/domain/classify/README.md`:
- Around line 5-8: Add a README package-table row for TestSourceFilter.kt,
describing its public split, isTestSource, and Split APIs, so the documentation
matches the new classifier source.

Align the implementation-ownership contract.
Lines 14-15 state that every Android capability is implemented in :app, but Lines 18-22 identify AndroidProjectWatcher and deploy services inside :quickbuild:core. Lines 48-49 repeat the :app ownership claim for data/.
Restrict the :app statement to app-owned port implementations, or document the core-owned Android adapters separately.

Keep watcher filesystem work off the caller thread.
start() recursively walks the project and registers observers synchronously. restampSettled() stats files on the unconstrained scope. Enforce an IO-backed dispatcher at the watcher boundary. If registration becomes asynchronous, make startup and stop() lifecycle-safe; cancellation can finish the non-suspending walk and leave observers untracked.

Guard registerCreatedTree against a post-stop() registration.
onEvent runs on the FileObserver thread. A callback in flight during stop() can enter registerCreatedTree after observers.clear(). registerCreatedTree then starts new observers that no longer sit in observers, so stop() never stops them. Their inotify watches stay active for the process lifetime.
Record the stopped state and check it inside the same lock.
🔒️ Proposed fix
private var pollJob: Job? = null
+
+ /** Set by [stop] under the [observers] lock, so a late inotify callback cannot re-register. */
+ private var stopped = false synchronized(observers) {
+ stopped = true
observers.forEach(FileObserver::stopWatching)
observers.clear()
} internal fun registerCreatedTree(dir: File) {
synchronized(observers) {
+ if (stopped) return
// Built fully, then published, so a live iteration of observers never sees a
// half-built batch.
val fresh = arrayListOf<FileObserver>()If start() must stay usable after stop(), reset stopped in start() as well.

Add the TestSourceFilter.kt row.
This PR adds TestSourceFilter.kt to domain/classify/, with a public split, isTestSource, and Split. The package table omits it, so the README no longer describes the package it documents.

Part 5/11 of the stacked split of #1669 (requested by Akash). Base: feature/ADFA-4128-qb-04-runtime. Stack overview + review mechanics: PR 1 (#1713). Terms are defined in quickbuild/README.md (lands in PR 1).
This is the first of several PRs for the Quick Build core that runs inside of Code on the Go.
Lets Quick Build notice every change a developer makes, however it arrives, so nothing ever builds stale.
