Description of Change

This revives @jonathanpeppers' #18318 and enables the deterministic MemoryAnalyzers Roslyn analyzer for Controls.Core at error severity.

The analyzer is already used by Microsoft.Maui.Core. It detects unsafe ownership patterns in Apple NSObject subclasses:

• MEM0001 — public events can retain subscribers.
• MEM0002 — strong-reference members can participate in native/managed retain cycles.
• MEM0003 — instance event subscriptions require deterministic teardown.

The large legacy compatibility surface needs a fix-first, suppression-second approach. This PR therefore combines specific justified suppressions with targeted lifecycle fixes.

Root Cause and Key Fixes

• ShellSectionRenderer's UIKit navigation and gesture delegates strongly referenced their owning renderer, creating a real retain cycle. They now use WeakReference<ShellSectionRenderer> and ignore callbacks after disposal.
• ShellRenderer cleanup now runs through the normal IElementHandler.DisconnectHandler() path as well as Dispose(bool), clears the Shell-to-handler reference, prevents in-flight current-item transitions from recreating or retaining renderers after teardown, cancels active native transition animations before disposal, observes late faults from custom transitions after cancellation, and detaches item-renderer views/controllers before disposing them.
• ShellFlyoutRenderer makes both native and managed disposal paths idempotent, can be disposed safely before AttachFlyout, and tears down native views and gesture recognizers before base.Dispose(disposing).
• ShellFlyoutContentRenderer preserves the shipped public WillAppear/WillDisappear events, clears subscribers during disposal, ignores late UIKit lifecycle callbacks after disposal, and owns/disposes asynchronous background-image service results when loads are replaced, become stale, or complete after teardown, and detaches its child table-controller view before disposing the controller.
• ShellSectionRootRenderer ignores late UIKit layout callbacks after disposal instead of dereferencing its released container view, and now calls base.Dispose(disposing) so its native controller resources are released deterministically.
• TableViewModelRenderer uses a named ModelChanged handler and unsubscribes it during disposal. TableViewRenderer disposes replaced and final sources deterministically.
• TableViewModelRenderer tracks the tap and long-press recognizers it owns, then removes and disposes them when a source is replaced.
• ContextActionsCell removes managed subscriptions during disposal while retaining its native content cell for late UIKit layout and reuse callbacks.
• Secondary toolbar items retain the originally-created native content control so its TouchUpInside handler is always removed even if CustomView is replaced before disposal.
• Owned UIKit views and recognizers are removed and disposed where teardown was incomplete.
• The internal NativeViewPropertyListener implements INotifyPropertyChanged.PropertyChanged explicitly instead of suppressing a public event.

There is no breaking public API change. PublicAPI.Unshipped.txt intentionally records three new protected Dispose(bool) overrides on public compatibility types; these are non-breaking API additions required for deterministic cleanup. Label.~Label() already exists in the merge base and is only reordered. Existing shipped compatibility events remain public.

Analyzer Findings

The analyzer surfaces roughly 226 findings across legacy compatibility renderers and modern handlers. Each is handled individually:

• Real fixes are used where ownership or teardown can be corrected safely.
• Suppressions are retained only where the reference is intentionally owned for the renderer lifetime or the public member is shipped compatibility API.
• Every suppression names the concrete ownership or teardown behavior it relies on.

Regression Coverage

• ShellSectionDelegatesDoNotRetainRenderer directly roots the native delegates and proves they no longer retain ShellSectionRenderer.
• DisconnectShellDuringCurrentItemChangeDoesNotRecreateRenderer forces a current-item continuation to resume after disconnect and proves no renderer is recreated or retained.
• DisconnectShellDetachesCurrentItemRendererBeforeDisposal proves the current item renderer has neither a parent controller nor a superview when disposal begins.
• DisconnectShellCancelsActiveItemTransitionBeforeDisposal proves teardown removes live native animations, releases the transition await, and disposes both renderers exactly once.
• DisconnectShellDisposesAllPendingItemRenderers proves every superseded renderer awaiting a transition is disconnected and disposed exactly once.
• StaleShellFlyoutBackgroundImageIsDisposed blocks an image load, invalidates its source, resumes it, and proves the stale image-service result is disposed.
• DisposedShellSectionRootIgnoresLateLayout disposes the native root renderer and proves a subsequent UIKit layout callback is harmless.
• DisposedShellFlyoutContentIgnoresLateLifecycleCallbacks proves UIKit appearance and layout callbacks no longer touch released native state after disposal.
• DisposedShellFlyoutContentDisconnectsHeaderAndFooterHandlers proves final flyout teardown clears both hosted MAUI handlers and detaches their native views, including the child table-controller view; it fails without the fix and passes on iOS and MacCatalyst.
• DisconnectingReparentedUIContainerPreservesSharedHandler proves disposing an old Shell title container does not disconnect the shared handler after UIKit reparents its platform view; it fails without the fix and passes on iOS and MacCatalyst.
• DisposedShellTableSourceClearsScrolledSubscribers proves final flyout teardown releases every public ScrolledEvent subscriber; it fails without the fix and passes on iOS and MacCatalyst.
• ShellFlyoutRendererDisposalIsIdempotentAfterNativeTeardown proves native-side teardown prevents later explicit disposal from rerunning managed cleanup.
• UnattachedShellFlyoutRendererCanBeDisposed proves direct repeated Dispose(true) is safe before AttachFlyout; it fails with NullReferenceException without the guard.
• TableViewSourceReplacementUnsubscribesPreviousSource proves source replacement swaps the ModelChanged subscriber and does not accumulate source-owned recognizers.
• ContextActionsCellDisposalUnsubscribesCell proves disposed native context-action cells detach managed subscriptions while remaining safe for late UIKit size and reuse callbacks.
• SecondaryToolbarItemDisposalUnsubscribesAfterCustomViewReplacement proves property updates no longer target a replacement custom view and both managed PropertyChanged and the original native TouchUpInside subscription are removed during disposal.

The broader Shell renderer graph has a separate pre-existing lifetime issue: full-tree collection fails on both the base branch and this PR. This PR intentionally does not claim to fix that unrelated ownership chain.

What NOT to Do

• Do not hide shipped public compatibility events behind explicit interface implementations.
• Do not put Shell cleanup only in Dispose(bool); normal MAUI teardown uses DisconnectHandler().
• Do not use full Shell-tree collection as a proxy for the focused UIKit delegate cycle.
• Do not suppress event subscriptions that can instead be unsubscribed deterministically.

Verification

Controls.Core builds cleanly with zero warnings and zero errors:

dotnet build src/Controls/src/Core/Controls.Core.csproj -c Release -f net10.0-ios26.0
dotnet build src/Controls/src/Core/Controls.Core.csproj -c Release -f net10.0-maccatalyst26.0

Empirical device-test results:

• iOS Shell: 218 passed, 0 failed
• MacCatalyst Shell: 52 passed, 0 failed
• Android Shell regression: 69 passed, 0 failed
• iOS Memory: 58 passed, 0 failed, 1 ignored
• MacCatalyst Memory: 57 passed, 0 failed, 1 ignored

Exact UI-test reproductions from the failed CI run:

• iOS: 12 passed, 0 failed — TitleViewSetOnShellWorksAfterNavigation, ShellItemItemsClearTests, Issue3276Test, GitHub1567Test, and eight ListView/context-action crash repros.
• MacCatalyst: 1 passed, 0 failed — Issue3276Test.

Focused delegate-retention comparison over 50 iterations:

• Base branch: 0/50 passed
• This PR: 50/50 passed on both iOS and MacCatalyst

Android has no direct analyzer or runtime behavior change; its run validates regression safety.

Current-head CI and Merge Recommendation

Fresh current-head builds target merge SHA 7085aea from head a6a6559:

• maui-pr 1523478 succeeded.
• Device 1523482 succeeded; all seven Helix jobs and 53/53 work items passed.
• UI 1523481 is mechanically red only for the recurring macOS Issue20855.GroupedCollectionViewItems screenshot delta (0.54-0.55%) and the wrapper's full-suite retry exceeding the 180-minute job limit.

The exact macOS visual signature recurs on unrelated builds 1505713, 1511724, 1511860, 1514713, and 1517676. The latest actual image differs from the unrelated PR #36552 failure image in only 0.2175% of pixels, with a maximum channel delta of 3. No further product change or retry is warranted; clearing the required check needs a separate baseline/test-infrastructure fix or maintainer override.

MauiBot found no actionable issue on the current head, Copilot reviewed all 57 files without current-head comments, and all review threads are resolved. Engineering verdict: ready to merge after human approval.

Note

🤖 AI-generated comment (GitHub Copilot CLI, on behalf of @kubaflo). Please verify before relying on it.

@jonathanpeppers — thanks, you were exactly right: the Compatibility/.editorconfig downgrade just silenced the analyzer on the legacy renderers instead of enforcing it. That is now removed and the analyzer is enforced at error across all of Controls.Core.

Every finding is handled individually per the README rules, fix-first:

• MEM0003 → static handler where the body is stateless (e.g. ShellTableViewSource.OnViewMeasureInvalidated).
• MEM0002 → WeakReference<T> for nested NSObject delegates holding a strong back-ref to their renderer (ShellSectionRenderer.GestureDelegate / NavDelegate — the retain cycle from the wiki).
• MEM0001 → non-public / explicit-interface events (ShellFlyoutContentRenderer.WillAppear/WillDisappear).
• Added real Dispose/-= teardown where it was missing.
• Everything else is a specific justified [UnconditionalSuppressMessage(...)] naming the concrete teardown method — no blanket severity change.

226 findings resolved (~195 legacy + 31 modern); Controls.Core builds clean of MEM/CS/RS on both net10.0-ios26.0 and net10.0-maccatalyst26.0.

Given the volume, most legacy findings are conservative justified suppressions rather than behavioral changes — happy to convert more into real fixes wherever you'd prefer. Ready for another look when you have a moment.

Adversarial code review — PR #36312

Methodology: this change was independently reviewed by 3 models, and single-reviewer findings were re-tested in a dispute round. Only findings that survived cross-validation are reported. This is a code-only assessment — CI status is out of scope.

This PR clears ~226 MemoryAnalyzers diagnostics on Controls.Core, mostly via [UnconditionalSuppressMessage] with a handful of behavioral fixes (WeakReference conversions, static-method conversions, added Dispose teardown). The bulk holds up well: the WeakReference self-cycle conversions in ShellSectionRenderer, the new ShellFlyoutContentRenderer.Dispose that fixes a real pre-existing Shell.PropertyChanged leak, and the "proven safe in HandlerDoesNotLeak" suppressions all check out. The items below are the exceptions.

❌ Public API break + build break — ShellFlyoutContentRenderer (already flagged inline at :47)

ShellFlyoutContentRenderer is a public class, and its WillAppear / WillDisappear events are shipped public API — both are present in PublicAPI.Shipped.txt for net-ios and net-maccatalyst. Demoting them to private + explicit-interface events removes shipped API. Beyond the source-compat break the existing review already notes, this should also fail the build with RS0017 (the PublicAPI analyzer), because no matching removal entries were added to PublicAPI.Unshipped.txt. And internally these events have zero subscribers, so the demotion buys nothing. Recommend keeping them public and suppressing MEM0001 — consistent with how every other legacy renderer event in this PR was handled.

⚠️ ContextScrollViewDelegate.Dispose — dispose without remove (inline at :228)

⚠️ TableViewModelRenderer — MEM0003 justification addresses the wrong leak vector (inline at :49)

See the inline comments for details.

💡 Minor

• CellTableViewCell.PropertyChanged (already flagged inline at :19): worth adding that this field is effectively dead — nothing ever assigns it (the .PropertyChanged += sites are on the ViewCell model, not this field). The inaccurate "cleared in Dispose" justification is therefore harmless in practice; the cleanest resolution may be to just remove the unused field rather than justify it.
• ShellFlyoutContentRenderer.Dispose async-callback window: the new Dispose nulls _shellContext / _bgImage before base.Dispose, while the pre-existing UpdateFlyoutBgImageAsync LoadImage callback dereferences them. Both dispute-round reviewers agreed the View is null guard plus synchronous Dispose ordering make an actual NRE unlikely, so this is defensive only — but a _shellContext is null check alongside the existing View is null guard would close the window cheaply.

Tests

No tests were added. These suppression justifications are lifetime claims that only device/memory tests (e.g. MemoryTests.HandlerDoesNotLeak) can truly validate; findings at ContextScrollViewDelegate and TableViewModelRenderer describe leak paths that wouldn't be caught without such coverage.

3 independent reviewers · adversarial consensus · comment-only (approval is a human decision).

[PureWeen]

Adversarial re-review (fresh pass) — methodology: 3 independent reviewers + a dispute round on split findings.

This was a second, independent pass over the unchanged head. It re-confirmed the previously posted event-demotion / public-API concern in ShellFlyoutContentRenderer (already flagged — not re-posting), and surfaced one new finding, added inline:

• ⚠️ ShellFlyoutRenderer.Dispose calls base.Dispose(disposing) before the new native-teardown block, so View?.RemoveGestureRecognizer(...) runs against an already-disposed controller and no-ops. Fix is to move base.Dispose to the end, matching the sibling ShellFlyoutContentRenderer.Dispose in this same PR.

All other new candidates raised during this pass were investigated and discarded as pre-existing/out-of-scope, mitigated by base.Dispose tearing down the view tree, or style-only. CI status is out of scope for this review.

[kubaflo]

AI-assisted review follow-up for review 4761788649: its NEEDS_CHANGES finding is already fixed in the current head.

Commit c49b7e8614a implements authoritative UIContainerView.Disconnect() teardown (detach the captured native view, clear ownership, and call DisconnectHandler()), and Dispose(bool) invokes it. ShellFlyoutContentRenderer.Dispose(bool) disposes both header and footer containers. DisposedShellFlyoutContentDisconnectsHeaderAndFooterHandlers verifies both MAUI handlers become null and both native views detach.

The deterministic gate failed without this fix (214/215; retained LabelHandler) and passed with it (215/215). Current-head validation is iOS Shell 216/216 and MacCatalyst Shell 50/50. There is no unresolved review thread for this already-addressed finding.

Tests Failure Analysis

@github-actions[bot] — new AI test-failure analysis results are available based on this last commit: a6a6559.

Test Failure Review: Not ready - click to expand

Overall verdict: Not ready

No known PR-caused failure remains on a6a6559. The latest MauiBot review identified four lifecycle/test-reliability gaps; all four are fixed in a6a6559, all threads are resolved, and focused Apple validation is green. Merge readiness is pending only the replacement automated review and current-head CI.

Coverage: Fresh builds maui-pr 1523478, device 1523482, and UI 1523481 target merge SHA 7085aea from head a6a6559.

Failure	Verdict	On base?	Evidence
Reparented Shell title handler	PR-caused, fixed	no	Commit d54ad27 fixed the obsolete-head iOS regression. The exact CI Issue12888.TitleViewSetOnShellWorksAfterNavigation passed on the replacement head, and the ownership gate fails without the fix and passes with it.
Flyout table-controller view remains attached	PR-caused, fixed	no	The expanded teardown regression fails without the fix; combined no-fix iOS gate was 216/218. a6a6559 removes the loaded child view before controller teardown.
Unattached ShellFlyoutRenderer.Dispose(true)	PR-caused, fixed	no	New regression fails without the fix with NullReferenceException; a6a6559 guards observer cleanup before AttachFlyout.
Late custom transition fault	PR-caused risk, fixed	—	If cancellation wins, the original transition task is now observed asynchronously and late non-cancellation faults are logged without blocking teardown.
Delayed image test wait	Test reliability, fixed	—	The test intentionally ignores cancellation to produce a stale result, but its wait is now bounded to 30 seconds with a clear timeout failure.
Apple Shell regression suites	No failures found	—	Clean iOS run: 218/218. MacCatalyst run: 52/52. Controls.Core iOS and MacCatalyst builds: 0 warnings, 0 errors.

Recommended action

Wait for the fresh automated review and builds 1523478, 1523482, and 1523481. If they remain green or contain only failures verified against main, the PR is merge-ready.

Evidence details

Deterministic review gate:

• Without the table-view detachment and null guard: iOS Shell 216/218.
• Exact failures: DisposedShellFlyoutContentDisconnectsHeaderAndFooterHandlers and UnattachedShellFlyoutRendererCanBeDisposed.
• With a6a6559: iOS Shell 218/218 and MacCatalyst Shell 52/52.

Prior current-head evidence retained:

• maui-pr 1523119 succeeded after an external JDK-download retry.
• Device 1523131 succeeded; all seven Helix jobs and 53/53 work items passed.
• Exact iOS Issue12888.TitleViewSetOnShellWorksAfterNavigation passed in CI.
• Prior UI failures were classified separately against latest main and historical unrelated runs; the replacement UI build will provide the final current-head verdict.

This may cause bugs by forcing views inside the table view to load and perform layout without accurate information (e.g. table view bounds, trait collection, layout margins, safe area insets, etc), and will also cause unnecessary performance overhead due to extra layout passes. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window.

📋 Pre-Flight — Context & Validation

Issue: #18318 - [ios] update MemoryAnalyzers package, add to Controls
PR: #36312 - [iOS/MacCatalyst] Controls.Core: Enable MemoryAnalyzers
Platforms Affected: iOS, MacCatalyst
Files Changed: 55 implementation, 2 test

Key Findings

• PR enables MemoryAnalyzers for Controls.Core and handles roughly 226 analyzer findings with targeted lifecycle fixes and justified suppressions.
• The active change set is broad iOS/MacCatalyst NSObject ownership cleanup across Shell, ListView, TableView, CollectionView/CarouselView, toolbar, gesture, modal, and compatibility renderer paths.
• Prior inline review errors about public API breakage, Shell disconnect cleanup, attached renderer disposal, stale callbacks, UIContainer ownership, TableView recognizer cleanup, and ContextActionsCell unsubscription appear addressed in current head.
• Regression coverage is device-test focused under src/Controls/tests/DeviceTests, especially Shell lifecycle and Memory tests; the supplied gate already passed, so the gate was not re-run.
• Candidate testing platform is ios; focused validation should use the device-test runner against src/Controls/tests/DeviceTests/Controls.DeviceTests.csproj with filters for the new Shell/Memory regression tests.

Code Review Summary

Verdict: NEEDS_DISCUSSION
Confidence: low
Errors: 0 | Warnings: 0 | Suggestions: 0

Key code review findings:

• ℹ No actionable code findings were found on current head.
• ℹ Required CI could not be fully verified from this unauthenticated environment; public checks were pending/undetermined with one likely infrastructure failure, so confidence is capped low.
• ℹ Blast radius is broad for iOS/MacCatalyst Shell/Flyout/ListView/TableView/CollectionView lifecycle paths, including startup/page initialization paths when those controls are used.

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
PR	PR #36312	Enable MemoryAnalyzers for Controls.Core, fix real iOS/MacCatalyst retain cycles and deterministic teardown gaps, and suppress only intentional ownership patterns.	✅ PASSED (Gate)	57 files	Original PR; gate result supplied by caller and not re-run.

🔬 Code Review — Deep Analysis

Code Review — PR #36312

Independent Assessment

What this changes: Enables MemoryAnalyzers for Controls.Core and adds iOS/MacCatalyst lifecycle/disposal fixes across Shell, ListView, TableView, CollectionView, toolbar, and compatibility renderers.
Inferred motivation: Reduce native/managed retain cycles and make analyzer suppressions match deterministic teardown behavior.

Reconciliation with PR Narrative

Author claims: Fix-first/suppression-second memory-analyzer enablement with targeted tests and no public API break.
Agreement/disagreement: Matches current code. Previously flagged lifecycle/API issues appear addressed in current head.

Prior Review Reconciliation

Prior ❌ Error Finding	Source	Status	Evidence
ShellFlyoutContentRenderer.WillAppear/WillDisappear hidden public API	MauiBot	✅ Fixed	Events are public at ShellFlyoutContentRenderer.cs:37,40.
Shell cleanup only ran from Dispose	MauiBot	✅ Fixed	IElementHandler.DisconnectHandler() delegates to shared cleanup at ShellRenderer.cs:569-572.
Shell item renderer disposed while attached	MauiBot	✅ Fixed	DetachRenderer removes view/controller before dispose at ShellRenderer.cs:270-287.
ContextActionsCell keeps _cell.PropertyChanged	MauiBot	✅ Fixed	Unsubscribed in dispose at ContextActionCell.cs:306.
TableView source recognizers remain attached	MauiBot	✅ Fixed	Recognizers removed/disposed at TableViewModelRenderer.cs:214-221.
Flyout late lifecycle callbacks after dispose	MauiBot	✅ Fixed	Disposed guards in lifecycle methods, e.g. ShellFlyoutContentRenderer.cs:365.
UIContainerView handler leak	MauiBot	✅ Fixed	Disconnect() detaches platform view and conditionally disconnects owned handler at UIContainerView.cs:150-163.
Shell active-transition teardown risk	MauiBot	✅ Fixed	Transition cancellation plus regression test DisconnectShellCancelsActiveItemTransitionBeforeDisposal.

Blast Radius Assessment

• Runs for all instances: Yes, for affected iOS/MacCatalyst compatibility renderers/handlers when used.
• Startup impact: Possible for Shell/Flyout setup paths.
• Static/shared state: No new broad static state; mostly instance lifecycle cleanup.

CI Status

• Required-check result: gh pr checks --required unavailable due missing auth.
• Fallback public check-runs: pending/in progress plus one failed maui-pr (Build .NET MAUI Build Windows (Debug)).
• Classification: failure appears infra/transient (microsoft-jdk-17.0.12-windows-x64.msi download response ended prematurely); overall CI still undetermined.
• Action taken: invoked azdo-build-investigator; ci-analysis skill unavailable; confidence capped low.

Findings

No actionable code findings found on current head.

External Output Contract

Consumer token/pattern	Producer location	Producer emission condition	Consumer assumption	Ordinary negative case	Downstream effect
N/A	N/A	No changed code classifies external tool output via regex/string literal	N/A	N/A	N/A

Failure-Mode Probing

• Disconnect during Shell item transition: cancellation removes active animations and disposes old/new renderers once.
• Late UIKit callback after dispose: affected flyout/root renderer paths now guard _isDisposed.
• Reparented shared title view: default UIContainerView no longer disconnects shared handler; flyout-owned containers opt in.

Verdict: NEEDS_DISCUSSION

Confidence: low
Summary: Code changes look sound and prior error-level findings appear fixed. I cannot return LGTM because required CI is not complete/verified and one current public check is failing with likely infrastructure failure.

🛠️ Fix — Analysis & Comparison

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix-1	Replace ShellRenderer's split DisconnectAndDispose / DetachAndDispose helpers with one teardown path backed by explicit disconnected-renderer tracking.	⚠️ Blocked	1 file	iOS/MacCatalyst/device-test builds passed, but iOS simulator deployment timed out. Structurally clearer than the PR but not empirically validated.
2	try-fix-2	Delay _currentShellItemRenderer promotion until after Shell item transition completion, keeping "current" as the committed renderer during animation.	❌ Fail	1 file	Regressed CanClearShellContent: delaying old-renderer disconnect temporarily double-registers Shell appearance observers.
3	try-fix-3	Infer UIContainerView handler ownership at disconnect time from captured view/handler/platform-view relationships instead of using the PR's explicit ownership flag.	❌ Fail	3 files	Missed legitimate flyout header/footer teardown; Disposed Shell Flyout Content Disconnects Header And Footer Handlers failed.
4	try-fix-4	Centralize ContextActionsCell teardown through a SetCell(...) path and have Dispose(bool) call SetCell(null, false) while preserving the content cell for late UIKit callbacks.	❌ Fail	1 file	Build passed, but iOS MemoryTests timed out after 3600s with XHarness exit code 80 (APP_CRASH) and no test counts.
PR	PR #36312	Current PR fix: explicit lifecycle cleanup, focused weak references, explicit ownership flags, early Shell old-renderer disconnect with outgoing tracking, and targeted suppressions/tests.	✅ PASSED (Gate)	57 files	Gate result supplied by caller; not re-run.

Iterative Learning

Candidate	Lesson fed into next iteration
try-fix-1	A unified Shell teardown helper can make the invariant clearer, but without device-test completion it cannot be selected over the PR's already-gated fix.
try-fix-2	Delayed promotion is not safe: Shell observer unregistration must happen synchronously at transition start, so the PR's early disconnect is load-bearing.
try-fix-3	Reparentable vs owned UIContainerView teardown cannot be reliably inferred from runtime identity alone; the PR's explicit ownership signal is necessary for flyout header/footer cleanup.
try-fix-4	Centralized ListView context-action cleanup is plausible statically, but the available iOS run ended in an app-crash timeout, so it cannot displace the current focused fix.

Candidate Details

try-fix-1 — Explicit ShellRenderer disconnect-state tracking

This candidate kept the PR's Shell transition state machine shape but replaced the two teardown helpers with one TeardownRenderer method that consults _disconnectedRenderers. When an old renderer is disconnected at transition start, it is recorded; later teardown removes it from the set and skips a second Disconnect().

Diff: recorded in ../try-fix-1/content.md as an excerpt.
Result: Blocked. Relevant builds succeeded, but the iOS Shell device-test deployment exceeded the environment timeout, so no passing test result was available.

try-fix-2 — Delayed current-renderer promotion

This candidate changed the Shell transition model: _currentShellItemRenderer stayed on the old renderer during animation; the new renderer stayed _incomingRenderer until the transition completed.

Diff: recorded in ../try-fix-2/candidate.diff and summarized in ../try-fix-2/content.md.
Result: Failed. The candidate regressed CanClearShellContent because old appearance observers remained registered until transition completion. The PR's current early-disconnect model is required to maintain the observer-count invariant.

try-fix-3 — Inferred UIContainerView ownership

This candidate removed the PR's explicit ownsHandler constructor signal and attempted to disconnect only when the captured handler/platform view relationship proved ownership at teardown time.

Diff: recorded in ../try-fix-3/content.md.
Result: Failed. The heuristic skipped required flyout header/footer handler teardown and failed Shell lifecycle tests, showing explicit ownership is safer and clearer.

try-fix-4 — Centralized ContextActionsCell teardown

This candidate routed ContextActionsCell disposal through a centralized SetCell(...) helper instead of duplicating _cell.PropertyChanged -= OnCellPropertyChanged in Dispose(bool).

Diff: recorded in ../try-fix-4/fix.diff and summarized in ../try-fix-4/content.md.
Result: Failed. The code built and self-review found no issues, but the iOS MemoryTests run timed out with XHarness APP_CRASH, so it did not produce a successful regression result.

Cross-Pollination

Model	Round	New Ideas?	Details
claude-opus-4.6	1	Yes	Proposed explicit ShellRenderer disconnected-state tracking.
claude-opus-4.7	1	Yes	Proposed delayed current-renderer promotion; test failure proved early disconnect is required.
gpt-5.3-codex	1	Yes	Proposed inferred UIContainerView ownership; test failure proved explicit ownership flag is required.
gpt-5.5	1	Yes	Proposed centralized ContextActionsCell teardown; build passed but iOS app-crash timeout prevented validation.
all	Exhaustion	No	Further variants would either reintroduce the failed delayed-promotion/inferred-ownership assumptions or become trivial reshuffles of the PR's current fix.

Exhausted: Yes
Selected Fix: PR #36312 — It is the only candidate with a completed passing gate. The failed alternatives also support key design choices in the PR: early Shell old-renderer disconnect, explicit UIContainer ownership, and direct deterministic teardown for analyzer-owned subscriptions.

🏁 Report — Final Recommendation

Comparative Analysis — PR #36312

Candidates Compared

Candidate	Result	Rank	Rationale
pr	Passed supplied gate	1	The submitted PR is the only fully validated candidate. It enables MemoryAnalyzers, fixes concrete iOS/MacCatalyst ownership problems, preserves public compatibility surface, and includes targeted device-test coverage.
pr-plus-reviewer	Equivalent to pr	2	The expert-review pass produced no actionable source changes to apply, so this candidate is functionally identical to pr. It is ranked just below pr because there is no actual improvement over the already-gated PR fix.
try-fix-1	Blocked	3	Structurally attractive ShellRenderer teardown centralization, but its device-test run did not complete. Because candidates without completed regression validation must rank below candidates with a passing gate, it cannot beat pr.
try-fix-2	Failed	4	Delaying _currentShellItemRenderer promotion regressed CanClearShellContent by allowing old and new Shell appearance observers to coexist during transition. This proves the PR's early old-renderer disconnect is load-bearing.
try-fix-3	Failed	5	Inferring UIContainerView handler ownership missed required flyout header/footer handler teardown and failed Shell lifecycle tests. This proves the PR's explicit ownership flag is necessary.
try-fix-4	Failed	6	Centralized ContextActionsCell teardown built cleanly and self-reviewed cleanly, but the iOS MemoryTests run timed out with XHarness exit code 80 (APP_CRASH) and produced no passing test counts. It must rank below passing candidates.

Winning Candidate

Winner: pr

The raw PR fix wins because it is the only candidate with a completed passing gate. The expert-review pass found no actionable change to apply, so pr-plus-reviewer collapses to the same implementation rather than becoming a distinct improvement. The try-fix failures also strengthen confidence in the PR's design: early Shell old-renderer disconnect, explicit UIContainerView ownership, and direct deterministic teardown are not incidental complexity; they preserve tested lifecycle invariants.

Candidate-Specific Notes

try-fix-1 remains a plausible future cleanup idea because explicit disconnected-renderer tracking would make Shell teardown state easier to audit, but it did not complete the iOS simulator validation. It should not displace a passing PR fix.

try-fix-2 should not be revived as-is. Its delayed-promotion model makes _currentShellItemRenderer semantically cleaner, but it delays observer unregistration and regresses existing Shell behavior.

try-fix-3 should not be revived. Runtime inference of handler ownership is too fragile for flyout header/footer lifetimes.

try-fix-4 should not be selected without a clean device-test pass. Its refactor may be reasonable in isolation, but the available run ended in app-crash timeout and therefore fails the required ranking rule.
