Bug Fixes
- Fixed an issue where the app's ready state was not properly reset when components unmount.

Walkthrough

A helper function resetReady is introduced to manage the app element's data-ready attribute during the cleanup phase of an effect, resetting it to "false" on unmount. The function has a parameter mismatch between its declaration and usage.

Changes

Cohort / File(s)	Summary
Cleanup helper for app-ready lifecycle `frontend/src/app/components/app-ready.tsx`	Introduces `resetReady` helper that sets the `data-ready` attribute to `"false"` and invokes it in the effect cleanup phase on unmount. ⚠️ Note: Function declaration lacks parameters but is called with `appElement` as argument.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

The scope is minimal (single file, straightforward logic), but the parameter mismatch between the function declaration and its call site warrants careful verification.

Mark app container ready after initial render #79: Implements setting and resetting the same data-ready flag with cleanup logic on unmount, following a related pattern.

Poem

🐰 A ready flag that had its day,
Now reset when components fade away,
Though parameters play a tricky game,
The cleanup phase calls out its name! 🔄

Check name	Status	Explanation
Title Check	✅ Passed	The PR title "Ensure app ready effect cleans up state" directly and clearly summarizes the main change introduced in this pull request. The summary indicates that a resetReady helper function was added and called during the effect's cleanup phase to reset the data-ready flag on unmount, which aligns perfectly with the title's message. The title is concise, readable, and avoids vague or generic language, making it clear to teammates scanning the history that this PR addresses cleanup behavior in the app-ready effect.
Description Check	✅ Passed	The pull request description provides substantive information about the changes, including a summary section that explains the resetReady helper and cleanup behavior, and a testing section that explicitly states "not run." However, the description does not follow the repository's template structure exactly: it omits the required "PR Type" field at the beginning and uses different section headings ("Summary" and "Testing" instead of "Short Description" and "Tests Added"). Despite these formatting differences, the description is mostly complete with clear, specific information about what was changed and the testing status, rather than being vague or off-topic.

frontend/src/app/components/app-ready.tsx

        cancelAnimationFrame(frame2)
      }
+
+      resetReady(appElement)


Fix resetReady invocation argument mismatch

resetReady is defined without parameters but the cleanup calls it as resetReady(appElement). With TypeScript's strict function arity checking this yields “Expected 0 arguments, but got 1” and the component fails to compile, preventing the build. Call the helper with no arguments or accept the element parameter.

Useful? React with 👍 / 👎.

27-36: LGTM! Cleanup logic is well-structured.

The cleanup function correctly:

Cancels scheduled animation frames before resetting state

Handles all timing scenarios (cleanup before/during/after frame execution)

Ensures clean state on unmount by resetting the data-ready attribute

This approach prevents the markReady callback from executing after unmount and properly resets the ready state.

frontend/src/app/components/app-ready.tsx

+    const resetReady = () => {
+      appElement.setAttribute('data-ready', 'false')
+    }


⚠️ Potential issue | 🔴 Critical

Function signature inconsistent with usage.

The resetReady function is declared without parameters but is called with appElement as an argument on line 35. While JavaScript ignores extra arguments, this creates confusion and inconsistency.

Apply one of these fixes:

Option 1 (Recommended): Remove the unnecessary argument from the call

- resetReady(appElement) + resetReady()

Option 2: Add parameter to function and remove closure dependency

- const resetReady = () => { + const resetReady = (element: HTMLElement) => { - appElement.setAttribute('data-ready', 'false') + element.setAttribute('data-ready', 'false') }

Option 1 is preferred since the closure already provides access to appElement.

Committable suggestion skipped: line range outside the PR's diff.

🤖 Prompt for AI Agents

In frontend/src/app/components/app-ready.tsx around lines 19 to 21, the resetReady function is declared with no parameters but is called with appElement on line 35, creating an inconsistent signature; fix by removing the unnecessary argument from the call site so resetReady() is invoked without parameters (preferred), or alternatively change the function to accept a parameter (e.g., element) and use that instead of the closure—apply one of these fixes and ensure the call and function signature match.
