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.

Not taking it here. No JacocoCoverageVerification exists anywhere in this repo, so gating one module of ~50 gives it a different build contract from every other one. The module currently reads 97.1% line and 91.6% branch, so a 0.90 branch gate has 1.6 points of headroom and would go red on a routine defensive branch. If we want enforcement it belongs on jacocoAggregateReport, applied once.

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.

Not taking it as filed. start() runs on a dedicated single-thread QuickBuildSession executor, deliberately off Main, so the caller thread being protected is not the one at risk. Making registration async opens a window where the session is live but unwatched, and saves in that window are silently dropped, which is the failure this feature exists to prevent. The narrower version, suspending start() and wrapping the walk in withContext(Dispatchers.IO) while still awaiting it, is a reasonable follow-up.

…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.

Release native watches when scope completes.
Cancelling the injected CoroutineScope cancels pipelineJob and pollJob, but it does not call stop(). The FileObserver instances remain active, and callbacks can continue adding events to the open unlimited rawEvents channel without a collector. Register idempotent completion cleanup that stops the observers, clears observers, and closes rawEvents; add a cancellation regression test.

Handle onBatch failures inside the collecting coroutine.
If onBatch throws, the collecting scope.launch terminates and propagates the exception to the scope. With supervisor semantics, pollJob can continue writing to the unlimited rawEvents channel without a collector. Catch non-cancellation failures, log them, and apply the watcher’s explicit failure policy.

Initialize deletion tracking before starting FileObserver instances.
When a file is deleted after initial.forEach(FileObserver::startWatching) but before pollLoop() calls initFingerprints(), reportDeletion() finds no fingerprint and drops the removal. The baseline then excludes the absent file, so onBatch does not receive the removal. Initialize fingerprints before starting observers, then let the first poll reconcile startup races. ChangedFiles.Known.removed must remain distinct from modified files for downstream compilation.

Recreate rawEvents when restarting the watcher.
start() documents restart support, but stop() closes the private val rawEvents channel. A new collector then completes immediately, and report() calls trySend on the closed channel. Post-restart changes cannot reach onBatch. Recreate the channel for each start, or remove the restart guarantee. Extend the restart test with a post-restart change assertion.

at line 128, Update the AndroidProjectWatcher start/stop lifecycle so restarting
creates a fresh rawEvents channel before collecting events, rather than reusing
the channel closed by stop(). Preserve report() delivery to onBatch after
restart, and extend the restart coverage to assert that a change made after
restarting is observed.

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.

:quickbuild:core:test— only this slice's files exist yet, so the module suite is exactly the slice suite: 17 test files (16 suites; RoomAppFixture is a fixture), 221 tests per variant across all 6 variants, 0 failures, 0 errors. Coverage 97.4% line / 94.9% branch.Coverage (JaCoCo at the stack tip, single run):
…quickbuild.dataWatchServiceoverflow paths need a real watcher…quickbuild.domain…quickbuild.domain.annotations…quickbuild.domain.classify…quickbuild.domain.watch14 source files in the diff, all 14 measured.
Slice 1 of 4 — next: deploy and reload (PR 6).
