Phase 3c: report handlers, the core report proxy, and the requestData confirmation.

Stacked on #7 (feat/phase-3b-secure-rects, itself stacked on #6, #5, #4, #3). This PR's base must be retargeted to nextgen after #3-#7 merge.

Summary

• Native pipeline, both platforms (ReportHandlerPipeline.java, BGSFlutterReportHandlerPipeline.m): the SDK's completion runs exactly once on every path (Dart reply, deadline, engine detach, unreachable Dart, error in the pipeline), never throws, never leaves the SDK waiting. isTerminating never reaches Dart and the report is not even read. No Dart handler registered / Dart not attached: completes at once.
• Report proxy (Dart, internal lib/src/report, Phase 4 exposes it): opaque handle plus operations, not a copy. id, type, summary, description, email, severity, labels (atomic replace), attributes (String/bool/int/finite double: what both SDKs carry). A late edit throws ReportClosedError (a StateError) and native ignores it. onAfter is at-least-once: each delivery has a stable deliveryId (before|after:<reportId>), Dart skips a repeat within the isolate. Attachments/screenshots: Phase 6 (documented TODO seam).
• Enums by value (7.4): the bridge declares no Pigeon enum (Pigeon sends ordinals); severity crosses as the SDK integer. Dart ReportSeverity.veryLow=1 ... blocker=5 (Android's name; low is iOS's alias for 1). test/fixtures/report_enums.json is extracted from BOTH SDKs' source by scripts/extract_report_enums.dart (--check) and compared with Dart/Java/ObjC; JUnit and XCTest compare it with the real SDK enums.
• requestData: answers null/nil for every type including vh, also on the replaced wrapper, containing a throwing or null callback (tests on both platforms).
• Pigeon: handler-phase flags, resetReportHandlers, per-field report operations keyed by handle, onReportHandlerRequest; codegen --check green.

SDK deadlines and threads, per platform and path

	Android 7.4.2	iOS (nextgen = beta7 headers)
live (isTerminating=false)	handler posted to thread BugseeReportHandlerThread (never main); SDK waits for the completion, ReportHandlerCallbackTimeout per handler (default 30 s, 0 disables), chain max(60 s, timeout). Source: ReportHandler.java, ReportHandlerChain.java (Step.arm, HANDLER_CHAIN_CAP_MILLIS), BugseeIssueReportingCoordinator.java ~L720-1120, OptionsDescriptors.java:34	handlers called on the MAIN thread, one after another, each completion waited for: 30 s per handler (kBGSReportHandlerCallbackTimeoutSeconds), 60 s chain. BGSIssueReportingCoordinator.m (timedCallbackWithContinuation, BGSReportHandlerDispatchLive), BGSContracts.h
terminating (true)	borrowed background thread (inline if none); crashing thread waits <= 3 s (TERMINATING_HANDLER_CAP_MILLIS) for both handlers; completion ignored	no producer today
recovered on next launch (false)	spawned daemon thread bugsee-report-handler-bounded (inline on the launching thread, possibly main, only if no thread can start); launching thread waits <= 3 s for the handler to RETURN; completion is Callback.NOOP, never awaited	GCD worker, NEVER main; caller waits <= 3 s (kBGSBoundedReportHandlerCapSeconds) for the handler to return; completion not waited for, but a late one re-persists the report until the bundle is assembled

The path is told apart by thread (Android: name, iOS: main or not) for the time budget only; it is never passed to Dart and never read as "recovered crash" (7.2.3). Android completes at once on every non-live path (nothing can be waited for, Dart is rarely attached yet); iOS recovery still asks Dart with a 2 s window. The SDKs' numbers above are extracted from source into the fixture (iOS: nextgen@0581aa02c; the iOS SDK repo has no beta7 tag, the shipped headers equal nextgen's).

Deadlock analysis

iOS calls the handler on the main thread and Dart's reply is delivered by the main thread; Android's inline fallbacks can too. A native wait for Dart's reply deadlocks on the very thread that must deliver it, and stalls the SDK's dispatch thread otherwise. So dispatch only registers the handle, arms the deadline, posts the request to the platform thread and returns; the SDK is already waiting on its own timer. Tests: a Java dispatch ON the single platform thread with Dart's reply queued behind it, a blocked platform thread, a worker dispatch while main is blocked (XCTest), and timing assertions (a timed wait still returns, so dispatch is timed < 500 ms). A static guard greps every file of the report path for blocking primitives (Semaphore/latch/.await/.take/Thread.sleep/.join/.wait/Future.get/dispatch_semaphore_wait/dispatch_sync/usleep/DispatchSemaphore/...) and allow-lists each synchronized with its reason.

The window: adaptive budget and its honest limits

• Dart's window is the SDK's budget less a margin of a third (at most 10 s): 20 s live (of 30), iOS recovery 2 s (of 3). Android follows the ReportHandlerCallbackTimeout option the same way.
• Limit: the SDK's per-handler timer starts when it QUEUES the handler (Android Step.arm(), iOS timedCallbackWithContinuation, before the hop to main); ours starts at handler entry. That wait (another report's slow app handler holding the shared Android dispatch thread, a busy iOS main thread) is not observable, there is no timestamp, so the margin absorbs it; a handler queued behind more than the margin can still overrun the SDK's deadline and an edit then is accepted although the SDK has moved on. This is documented in code, CLAUDE.md and PLAN.md ("inside" is not claimed unconditionally).
• What is observable is used: the hop to the platform thread after entry is measured and logged (delivery gap=... remaining=...) and deducted; Dart is told what is LEFT (deadlineMs at send time, so its timer closes no later than native); a window already over is completed, not offered to Dart.
• Check-and-apply is one step: an edit holds a per-handle lock across "is it live" + the change, and done flips under it; the SDK completion, Dart and the scheduler run outside any lock. An edit reported as applied therefore landed before the completion ran. Race tests (Java, XCTest: deadline vs edit, 1500 rounds, widened window) fail without the lock.
• Hot restart: resetReportHandlers (called first by start()) completes a previous isolate's outstanding deliveries instead of letting each wait for its deadline.
• Overrun: a Dart handler that runs past its budget is reported through FlutterError.reportError even if it makes no further edit.

Verification

Local (floor Flutter 3.41.0, JDK 21): dart format --set-exit-if-changed (lib test example/lib scripts pigeons), flutter analyze (also from a fresh clone), flutter test 200, Gradle JUnit, xcodebuild test -collect-test-diagnostics never 125, generate_pigeon.dart --check, extract_report_enums.dart --check, debug APK and iOS builds.

• Mutation checks (apply, see a test fail, restore): Dart (late-edit guard, dedupe, no-handler completion, ordinal severity, clear+add labels, native refusal ignored, never complete, phases/reset omitted, Dart deadline timer, overrun warning, enum/value/type drift, pigeon enum added, attribute validation); Java and ObjC (terminating reaches Dart, both completion guards removed, deadline values, isLive negated, severity range, clear+add labels, unique deliveryId, detach/reset do not finish, gap not deducted, expired still delivered, edit without lock, dispatch blocks, wrapper completes directly or always says main, attribute check removed); drift guards (circular-free SDK timings, blocking primitives in each file, monitors, completion called inside the lock). Redundant guards (the SDK completion has several) survive when removed one at a time by design and are killed together.
• Android emulator (API 33), real reports: the SDK launched with a throwaway token and produced real reports (Bugsee.upload, logException). Handlers ran on the SDK report thread; Dart edited and read the report back; completion by Dart; a late edit was refused with ReportClosedError; a handler that never answered was completed by the native deadline at exactly 20.000 s; resetReportHandlers completed an in-flight delivery (completed by=reset); the overrun was reported (ran past its 19999 ms budget); delivery gap/remaining logged. Temporary code reverted.
• iOS simulator: a dummy token is rejected by the SDK ("AppToken not found", SDK is not launched), so no real iOS report is possible. Verified through a synthetic report object and the registered wrapper (temporary harness, reverted): main-thread live dispatch returned in 1 ms and Dart completed it on main; off-main used the 2 s recovery window; terminating completed with no Dart round trip; a repeated after: was completed without running the handler.

NOT verified

• CI: GitHub Actions cannot start jobs (billing); nothing here ran in CI (gh pr checks below). The stable-Flutter leg, pub publish --dry-run and actionlint were not run (workflows untouched).
• Relaunch-after-crash on either platform (Phase 7); Android early-crash recovery never reaches Dart by design.
• A real iOS report (impossible with a dummy token); terminating on real devices; hot restart in a running flutter run (the sweep is unit-tested and exercised via a direct resetReportHandlers call on the emulator).
• The SDK-queue wait is not observable (see above); the margin is a judgement, not a measurement.

Corrected workbook row (Part 7.1.3 table, for the specs repo; Android column)

The workbook's Android recovery row says thread "main" and "completion waited for: yes". bugsee-android 7.4.2 source (ReportHandler.java Javadoc, BugseeIssueReportingCoordinator.notifyReportHandlersBounded / buildLiveBoundedDispatcher / dispatchBounded) says:

	Android	iOS
isTerminating	false	false (was YES before 7.0.0)
thread	a spawned daemon thread bugsee-report-handler-bounded (inline on the launching thread, which can be main, only if no thread can be started)	not main
completion waited for	no: the launching thread waits at most 3 s for the handler to RETURN, and the completion handed to the handler is a no-op (Callback.NOOP)	no, past the cap, but a late completion re-persists the report

📝 Summary

Summary by CodeRabbit

• New Features

  • Added Flutter report handlers for before and after report processing on Android and iOS.
  • Handlers can read and update report details, severity, labels, and attributes.
  • Added report snapshots, report type and severity enums, and input validation.
  • Added delivery deadlines, duplicate suppression, and reliable completion when handlers are unavailable or time out.
  • Terminating reports complete natively, while late edits are rejected.

• Documentation

  • Expanded guidance for report-handler behavior and validation checks.

This change adds report-handler delivery across Android, iOS, and Dart. Native pipelines manage before and after phases, deadlines, engine ownership, live report handles, and exactly-once SDK completion. Dart handlers can read and update report fields, labels, severity, and supported attributes while a handle remains live. The change also adds enum extraction and parity checks, pipeline tests, and source-level drift guards. Attachments and screenshots remain deferred.

Priority: ➖ Normal

Change: Feature

Merge Risk: ⚪ Minimal · up to 32d2b

The previously tight test timing limit has been relaxed, and no blocking issue remains. The change is mergeable after normal checks.

Security architecture risk: 🟡 Moderate · up to 32d2b

Report handling now crosses an asynchronous native/Dart boundary. Normal completion and late-edit controls are coordinated, but live report operations are not restricted to the engine receiving the report. This matters if engines have different trust levels. The timing window also cannot guarantee that accepted edits precede the SDK’s own deadline.

Retained concerns

• Medium · security · inferred: Live report authority is process-wide rather than engine-bound. Both platforms generate sequential rh-N handles and accept read, edit and completion calls without checking the engine owner stored on the handle. A caller able to send host messages from another attached engine could enumerate live handles, read report contents, change fields, or complete another engine’s report before its handler finishes. This is an isolation concern if engines have different trust levels; such a deployment was not established.

Security review details

Security Blast Radius

• inferred — The identified access path is confined to a host application process and requires native-channel access from an attached Dart engine. Its potential scope is any live report in that process, including email, description, labels and supported attributes. No cross-application, tenant, infrastructure or remote attack path was established.

Security Findings and Attack Paths

• inferred — If a secondary engine is less trusted, it can supply another live rh-N handle to report operations without receiving that report’s delivery. Besides disclosure and mutation, premature completion could close the rightful handler’s editing window. This is a newly introduced authority path, but a hostile-engine deployment and a verified exploit were not established.

Trust Boundaries and Controls

• observed — Native state remains the final control for report liveness: unknown or completed handles are rejected, completion is idempotent, and Dart marks its proxy closed before requesting completion. Owner identity controls cleanup, but is not checked by live report operations.

Resilience and Maintainability Implications

• observed — Dart catches handler failures and attempts completion in a finally block. Duplicate delivery suppression uses a bounded remembered-ID collection, so it is not a durable exactly-once guarantee. The proxy contract accordingly requires repeat-safe after-handler behavior.

Hardening Proposals

• proposed — Define whether all engines share report authority. If engine separation is required, bind every read, edit and completion to the calling engine’s native owner token. Unguessable handles can provide defense in depth but should not replace that authorization check.
• proposed — Preserve the distinction between best-effort handler edits and mandatory privacy filtering when exposing the proxy publicly. A stronger pre-submission guarantee would need authoritative SDK expiry or an SDK-level submission gate, rather than relying only on a wrapper-local timer.

Review of PR #8: report handlers, report proxy core, requestData

I reviewed the native pipelines, the Dart proxy and bridge, the Pigeon wiring, and the drift guards, with the Java, Dart and ObjC sources read in full. I ran no tests or builds. The review is static, against HEAD 61345b8. I did not modify any files.

Earlier findings: CodeRabbit's iOS ordering-guard finding is fixed by 61345b8. Both guards now slice dispatchOnce up to the isTerminating branch and assert no protected use appears before it, and each use must still exist after the branch.

Findings

#	Severity	Location	Summary
1	P3 Low	lib/src/bridge/bridge.dart:161 (inline)	setReportHandlers sets _phasesSent = true, so start() skips resetReportHandlers when handlers are registered before start(). After a hot restart, in-flight deliveries from the old isolate then wait out their deadline instead of being swept. This is debug-only and bounded by the deadline.

I found no P0–P2 issues. These are the checks I tried to break:

• Exactly-once completion: finish flips done under the per-handle lock, and the once-guard sits around the SDK completion. Both Android and iOS call the completion, Dart and the scheduler outside the locks. iOS lock order (editLock, then the pipeline lock) is consistent in finish, editHandle and reportForHandle.
• Detach race: attach and detach close the lookup/put/sweep gap by re-checking registrations.contains(target) after the handle is in the table. This holds on both platforms.
• Terminating path: The report is never read and Dart is never contacted. The guard now covers every protected use.
• Deadlock: Dispatch only registers, arms the deadline, posts and returns. It does not wait for Dart on either platform.
• Wire and type handling: Severity crosses as the SDK integer, with a 1..5 range check on both platforms and a 0 read mapped to null on iOS. Booleans are told apart from numbers on iOS with CFBooleanGetTypeID. Labels are replaced atomically.

Notes, not findings

• Dart timer vs native deadline: Dart's timer starts on receipt, so it closes slightly later than native by the channel transit time. The doc says "no later than native". This has no effect, because native refuses the late edit anyway and Dart then raises ReportClosedError.
• Delivery-id dedupe: _remember records the id before the handler runs. If a handler throws or overruns, a later same-isolate redelivery of that report and phase is completed without running the handler. This matches the stated design. Revisit it when Phase 4 documents retry semantics.
• Handle ownership: Handles are sequential rh-N and looked up by handle alone, with no owner check. This is fine under the same-app trust model that CodeRabbit's security review also assumes. Write that assumption down before the API becomes public, as CodeRabbit also suggested.
• FlutterError.reportError in finally: If a custom FlutterError.onError throws inside the overran branch of _deliverReport, _complete is skipped and native completes on its own deadline. This is an unlikely edge, so I did not file it.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted and CI can actually run. The PR states that nothing has run in CI because of the billing block, so the Gradle, XCTest and flutter test results rest on the author's local runs only.
3. Most important item: Finding 1 is optional and low priority. The CI gap is the real merge gate.
4. Positives:
   • The invariants are well documented, and the unobservable SDK queue wait is stated openly.
   • The drift guards read SDK timings from SDK source instead of comparing the wrapper to itself.
   • The tests are strong: race tests with a widened window, a dispatch on the platform thread itself, and timing assertions.
   • The enums cross by value rather than by Pigeon ordinal.

[claude]

Severity: P3 Low

Problem: setReportHandlers sets _phasesSent = true (line 161). start() only calls resetReportHandlers under if (!_phasesSent) (line 93). If a caller registers handlers before start(), the hot-restart sweep is skipped.

Impact: The PR description and start() doc say resetReportHandlers is called first by start() so a previous isolate's in-flight deliveries are completed. That only holds if start() runs first. In the other order, native keeps those handles, and each waits for its deadline (up to 20 s) instead of being completed. This is debug-only and bounded by the deadline, so it is not a correctness break.

Scenario: Hot restart. The new main() calls bridge.setReportHandlers(...), then bridge.start(). A report handed to the old isolate just before the restart is not completed by the sweep, so the SDK waits out the full deadline.

Fix: Track the reset separately, for example _resetSent. Have both setReportHandlers and start() send resetReportHandlers once, before the first setReportHandlerPhases. Alternatively, drop the _phasesSent guard around the reset in _start. The existing test only covers the start()-first order (test/report_handlers_test.dart:35,69), so add a case for the other order.

Review of PR #8 (re-review after push, HEAD e0d99f1)

I reviewed the changes since the last reviewed commit 61345b8, which are 4 commits (43eafe7, bcf0077, b6f8732, e0d99f1). I read the diffs of bridge.dart and secure_region.dart in full and read the surrounding code. The native non-test diffs are comment-only. I did not run tests or builds. I did not modify any files.

Earlier finding: fixed. My P3 finding was that setReportHandlers set _phasesSent, so start() then skipped resetReportHandlers. bcf0077 adds _sweepPreviousIsolate(). It runs once per isolate, is shared by start() and setReportHandlers, always runs before the first setReportHandlerPhases, and is not cached on failure. I traced these paths:

• setReportHandlers before start(): the sweep runs first and the registration is not wiped.
• start() before setReportHandlers: the sweep is a no-op the second time.
• Concurrent calls: both await the same sweep future. Each reads _onBefore/_onAfter after the await, so both send the same latest flags.
• Sweep failure: _swept is reset, and start() retries on the next call.

The test-fake fix for calls with no payload (e0d99f1) is correct.

Other changes checked, no issues found:

• _reportSafely wraps FlutterError.reportError in both the handler-threw and overran branches. A throwing app onError can no longer skip _complete. The new test covers the throw case. This also resolves the edge I listed as a note last time.
• Secure-rectangle retry, secure_region.dart:
  • Only the newest sequence decides success or failure, so a stale failure cannot mark native's state unknown.
  • _retryDue is set only by the timer and cleared by _send, so it cannot get stuck.
  • Past maxRetries, a changed state waits for the timer, so there is no per-frame flood.
  • The backoff is capped at maxRetryDelay, and the shift is capped at 20 doublings, so there is no overflow.
  • dispose() stops new timers.
• The native Java and ObjC diffs for the secure stores are comment edits only.

Findings

None new. No P0–P3 issues found in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can actually run. The PR states that nothing has run in CI because of the billing block, so the Gradle, XCTest and flutter test results rest on the author's local runs.
3. Remaining items, none blocking:
   • Before the API goes public, write down the same-app trust model for the rh-N handles. CLAUDE.md now records this.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4. The new CLAUDE.md text documents it as decided.
4. Positives: The sweep ordering is handled in both call orders with a test for each. The retry logic documents its invariants and covers the stale-sequence and no-timer paths. The docs and drift guards were updated together with the behaviour.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Raise the 500 ms wall-clock threshold to the 5 s ceiling used by the other tests.

This test measures the full sdk.submit(...).get(...) round trip. That includes executor thread creation and first-time class loading. On a loaded CI runner, these steps can take more than 500 ms. The assertion then fails even when dispatch never blocks on main.

The file states its own rule: "The timeouts are ceilings, not assertions about speed." dispatchingOnThePlatformThreadItselfNeverWaitsForDart follows this rule with a 5 000 ms ceiling. A blocking implementation still fails at 5 s, because main stays blocked until release.countDown(). The done.getCount() == 1 check at Line 746 already proves that the SDK thread returned while main was blocked.

Re-review of PR #8 (after push, HEAD f2d4486)

I reviewed the changes since the last reviewed commit e0d99f1: 151a6a8, d59d003 and the merge f2d4486. The merge adds nothing beyond those two commits. The diff covers four files:

• lib/src/secure/secure_region.dart
• test/secure_region_test.dart
• ReportHandlerPipelineTest.java
• .claude/CLAUDE.md

This is a static review. I did not run tests or builds, and I did not modify any files.

Earlier findings: fixed.

• CodeRabbit's 500 ms ceiling: d59d003 raises it to 5 s in aBlockedPlatformThreadDoesNotBlockTheSdkThread. This matches the other dispatch tests. The done.getCount() == 1 assertion still proves the SDK thread came back while main was blocked.
• iOS ordering guard and _phasesSent sweep: both were already closed in the previous round.

New secure-rectangle retry throttle (151a6a8). When the transport is known bad (_failures > maxRetries), a changed state now goes out once retryDelay has passed since the last attempt. Before, it waited for the whole backoff timer. I traced these cases:

• Throttle: _lastSend is set in _send and the wait is retryDelay - (now - lastSend). If the wait is zero or negative, the state is sent at once. Otherwise _expedite re-arms the single retry timer for the remaining wait.
• Single timer: _expedited is set once per wait, so frames in between cannot keep moving the timer. _send clears it, and every path that ends the wait goes through _send (timer fires → _retryDue → flush → _send).
• Stale replies: a stale success or failure is ignored by the sequence != _sequence check. So an old reply cannot re-arm the backoff or reset _failures after a newer send.
• Rate bound: each failed send re-arms the backoff timer. A moving region is therefore limited to about one send per retryDelay, and a dead transport is never hit per frame. The new test caps this at 11 sends in ~1 s.
• Null safety: retryDelay! is safe because _retry != null implies a non-null retryDelay.
• Dispose: _expedite and _armRetry respect _disposed.
• Oscillating states: if a state reverts to the failed one before the expedited timer fires, the timer still sends it, at most retryDelay after the last send. That matches the documented rule, so I don't count it as a defect.
• Clock: it is a monotonic Stopwatch, injectable for tests. The tests advance it together with the fake frame time.

The updated tests cover the recovery case (transport back, send within retryDelay), the rate cap, and that the latest state wins.

Findings

None new. No P0–P3 issues in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can run. Nothing has run in CI because of the billing block. The Gradle, XCTest and flutter test results rest on the author's local runs.
3. Remaining items, none blocking:
   • Document the same-app trust model for the rh-N handles before the API goes public.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4.
4. Positives: The throttle fix keeps the "never abandon a failed publish" invariant and removes a long window where a new region could sit unprotected. The CLAUDE.md rule and the tests were updated together with the behaviour.

Re-review of PR #8 (after push, HEAD bbf0289)

I reviewed the one commit since the last reviewed commit f2d4486: bbf0289. It changes one line in .claude/CLAUDE.md and no code. This is a static review. I ran no tests or builds and modified no files.

Earlier finding: fixed. CodeRabbit's last finding said the extract_report_enums.dart --check ... line in the Checks block was not a runnable command. bbf0289 replaces it with a comment line that says the script needs the SDK source files named in its header and is not a CI step, because the private SDKs are not vendored. I read the script header (scripts/extract_report_enums.dart:1-40) and it matches. The header names the required --android-*, --ios-* and --ios-source-ref inputs, and --check compares against the committed fixture instead of writing it. The fixture is still guarded in CI by test/report_enum_parity_test.dart, which compares it with the Dart, Java and ObjC copies and with the pins in native-versions.json.

Findings

None. I found no P0–P3 issues in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can run. Nothing has run in CI because of the billing block. The Gradle, XCTest and flutter test results rest on the author's local runs.
3. Remaining items, none blocking:
   • Write down the same-app trust model for the rh-N handles before the API becomes public.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4.
4. Positives: The docs now describe a workflow that can actually be followed. The only change this round is a documentation fix, and it matches the script's header.

Re-review of PR #8 (after push, HEAD 0cd1ce9)

I reviewed the four commits since the last reviewed commit bbf0289: f115db4, 703a859, a52371a and the merge 0cd1ce9. They bring the 3a/3b base-branch fixes into this branch. None of them touches the report-handler code (pipelines, Dart proxy, bridge, enums). This is a static review. I ran no tests or builds and modified no files.

What changed

• Docs: the lifecycle delivery-limit wording (PLAN.md, LifecycleHub.java, BGSFlutterLifecycleHub.h) and one phrase in secure_region.dart. Comment-only.
• Stuck-refresh cover (a52371a): SecureRectangleStore.java, BugseeFlutterPlugin.refreshPlacements and SecureRectangleStoreTest.java.

Stuck-refresh cover: traced, no defect found

• Oldest request counts: pull() sets refreshPendingSince with a compare-and-set before the throttled hook runs. A throttled pull therefore cannot hide an unanswered request. The first pull after a quiet period serves at elapsed 0, so ordinary running never trips the 1 s limit.
• Always cleared: refreshCompleted() is in a finally, so it also runs when no placements are attached. A pending mark cannot stick on an empty PLACEMENTS list. If placement.refresh() throws, the exception still reaches the main looper, as before.
• Race with an in-flight refresh: a pull that arrives during a running refresh fails the compare-and-set and is served from that refresh's read. That matches the documented "up to about one pull" staleness.
• Scope: only views placed on the pulled display are covered. Views with an absent placement are still skipped, and views with an unknown placement were already covered. A store with no pull hook never enters the stuck state.
• Clock: both clocks are monotonic (nanoTime), and the tests inject one.
• Tests: they cover the boundary (exactly REFRESH_STALE_MS serves normally, +1 covers), recovery on refreshCompleted, and refreshes that complete at 100 ms, 400 ms and 5 s pull intervals. A test for the no-hook case is also present.

Earlier findings: all remain fixed. I re-read the CodeRabbit items on the ReportHandlerPipelineTest.java timing ceiling (now 5 s) and the iOS/Android ordering guards in test/report_handlers_drift_test.dart. Both guards slice dispatchOnce up to the isTerminating branch.

Note, not a finding: the CI checkout has a locally modified .claude/CLAUDE.md that lacks the report-handler bullets and the extractor comment. That is a workspace artifact. HEAD:.claude/CLAUDE.md still contains them, and the PR diff for that file is one line.

Findings

None. I found no P0–P3 issues in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can run. Nothing has run in CI because of the billing block. The Gradle, XCTest and flutter test results rest on the author's local runs.
3. Remaining items, none blocking:
   • Write down the same-app trust model for the rh-N handles before the API goes public. CLAUDE.md now records it.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4.
4. Positives: The stuck-refresh fix tracks the oldest unanswered request, so pull rate and throttling cannot hide a blocked main thread. It fails closed, and a test pins each boundary.

Re-review of PR #8 (after push, HEAD 32d2b0b)

I reviewed the changes since the last reviewed commit 0cd1ce9. There is one new commit, the merge 32d2b0b. It brings in a38ef60, 977f0d4 and 080d30b from the 3a/3b base branches. None of them touches the report-handler code (pipelines, Dart proxy, bridge, enums, drift guards). This is a static review. I ran no tests or builds and modified no files.

What changed

• Docs: the lifecycle wording in PLAN.md and LifecycleHub.java (in-flight events return to the buffer only when the last receiver detaches), plus the matching BGSFlutterLifecycleHub.h comment. Comment-only.
• Secure-rectangle refresh tracking (977f0d4): SecureRectangleStore.pull() no longer marks a refresh as pending itself. The new refreshRequested() is called from the PullThrottle executor in BugseeFlutterPlugin, right before MAIN.post. Because the executor runs only for a request the throttle let through, a pull the throttle dropped no longer starts the stale clock.

Refresh tracking: traced, no defect found

• Problem it fixes: under the old code, a pull dropped by the throttle set refreshPendingSince with nothing in flight. If the SDK then went quiet for more than 1 s and pulled again, the next pull saw a "stale" request and covered the whole display on a healthy main thread. aPullTheThrottleDroppedLeavesNothingPending pins this case.
• Ordering: refreshRequested() runs before MAIN.post, so the task cannot complete and clear the mark before it is set. refreshCompleted() stays in the finally of refreshPlacements.
• Oldest request still counts: the compare-and-set keeps the first unanswered timestamp, so repeated requests behind a stuck main thread cannot hide it.
• Edge, not a finding: if a second request is posted while the first refresh is still running, the first one's refreshCompleted() clears the mark while the second is queued. Stuck-thread detection for that request then waits until the next posted request, about one pull later. This matches the documented "up to about one pull" staleness, and the stuck case still fails closed afterwards.
• Tests: the updated tests stub the hook with refreshRequested, and the rate test now calls both refreshRequested and refreshCompleted. The fake hook mirrors what the plugin's executor does.

Earlier findings: all remain fixed, and nothing in this push reopens them. These were the _phasesSent sweep, the iOS and Android ordering guards, the 5 s timing ceiling in ReportHandlerPipelineTest, and the extract_report_enums.dart line in CLAUDE.md. I re-read the ordering guards in test/report_handlers_drift_test.dart and the dispatch timing tests in ReportHandlerPipelineTest.java. Both guards slice dispatchOnce up to the isTerminating branch. The dispatch timing tests use 5 s ceilings.

Note, not a finding: the CI checkout has a locally modified .claude/CLAUDE.md. That is a workspace artifact and not part of the PR diff.

Findings

None. I found no P0–P3 issues in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can run. Nothing has run in CI because of the billing block. The Gradle, XCTest and flutter test results rest on the author's local runs.

   • Write down the same-app trust model for the rh-N handles before the API goes public. CLAUDE.md now records it.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4.
4. Positives: The refresh fix puts the "request in flight" bookkeeping where the post happens, and it adds a regression test for the dropped-pull case. The base-branch merge leaves the report-handler code untouched.

Re-review of PR #8 (after push, HEAD 9ea7362)

I reviewed the changes since the last reviewed commit 32d2b0b. They are b55d549, 7115800 and the merge 9ea7362. The whole diff is one line in PLAN.md: it removes a doubled word ("and and") in the lifecycle delivery-limit note. The two merges bring in nothing else. No code, tests, native sources, bridge or drift guards changed. This is a static review. I ran no tests or builds and modified no files.

Earlier findings: all still fixed.

• The _phasesSent / hot-restart sweep.
• The iOS and Android ordering guards, both now slicing dispatchOnce up to the isTerminating branch.
• The 5 s ceiling in aBlockedPlatformThreadDoesNotBlockTheSdkThread.
• The extract_report_enums.dart line in CLAUDE.md.
• The secure-rectangle retry and refresh tracking.

Note, not a finding: the CI checkout has a locally modified .claude/CLAUDE.md. That is a workspace artifact and not part of the PR diff.

Findings

None. No P0–P3 issues in this push.

Summary

1. Overall risk: Low.
2. Merge recommendation: Approve once the stacked base is retargeted to nextgen and CI can run. Nothing has run in CI because of the billing block, so the Gradle, XCTest and flutter test results rest on the author's local runs.
3. Remaining items, none blocking:
   • The same-app trust model for the rh-N handles is recorded in CLAUDE.md. Keep it there until the API goes public.
   • Revisit the "id recorded before the handler runs" dedupe semantics in Phase 4.
4. Positives: The push is a one-word documentation fix. The report-handler code is unchanged from the version already reviewed.
