-- **TODO:** reword the comment in `AddressBarButtonsViewController` to say the handler is held until the animation ends, rather than "never called". The wording will match the fix in `fix-ask-ai-chat-button-animation-leak`.
+- The comment in `AddressBarButtonsViewController` was reworded on 2026-10-15 to say the completion is held until the animation ends. The handler change is now identical to the one in `fix-ask-ai-chat-button-animation-leak`.
 
 ## fix-ask-ai-chat-button-animation-leak
 
-Branch `alex/fix-ask-ai-chat-button-animation-leak`. In progress. Separate production fix for the Ask AI Chat button animation in `AddressBarButtonsViewController` (`[weak self]`), plus a regression test.
+Branch `alex/fix-ask-ai-chat-button-animation-leak`, based on origin/main `e698211924`. **Done, not committed.** 2 files, +63/−3.
 
-- **Revised requirement after the audit:** the test must fail on main deterministically regardless of whether the display is asleep or awake. It asserts deallocation right after teardown, before the 0.2 s animation ends.
+- **Fix** in `AddressBarButtonsViewController.animateAskAIChatButtonContraction()`: `[weak self]` plus `guard let self`.
+  - The comment explains why: the completion is deferred until the animation ends, indefinitely while the display link is paused.
+  - `isAskAIChatButtonExpanded` changed from `private` to `private(set)` so the test can read it.
+  - The rest of the file was checked: the expansion animation has no completion handler, and the `asyncAfter` and `sink` closures already use `[weak self]`.
+- **Regression test:** `AddressBarTests.testWhenWindowIsClosedWhileAskAIChatButtonContracts_windowObjectsAreDeallocated`.
+  - It sets text in the address bar so the button expands, then calls `makeFirstResponder(nil)` to start the contraction.
+  - In the same autorelease pool, it closes and releases the window.
+  - It immediately asserts that `AddressBarButtonsViewController` and `TabCollectionViewModel` are released. There are no sleeps or waits, so the result doesn't depend on display state.
+- **Results:**
+  - main: 10/10 FAIL (5 with the display awake, 5 asleep).
+  - fix: 15/15 pass (asleep, awake, and `-test-iterations 5`).
+  - Full `AddressBarTests`: 0 failures. `test_WhenControlTextDidChange…` sometimes crashes with SIGINT; that is the `TestRunHelper` autorelease problem fixed in `fix-address-bar-tests-flakiness`.
+  - Lint: 0.
+- **Overlap:** `fix-address-bar-tests-flakiness` contains the same handler fix (the comment was aligned on 2026-10-15; the change is identical). Whichever lands first, the other must drop or rebase this hunk.
