Describe the final shipped behavior.
Line 3 describes an internal parity expectation and “POD-copy coverage.” Replace that development detail with the observable native-value-profile behavior so the assembled changelog remains one coherent release-note entry.
Based on learnings: Perry changelog fragments in changelog.d/ must describe the final shipped behavior as one coherent release-note entry and must not include separate development-slice narratives.
Suggested wording
-- Kept non-callable value-call errors catchable across the checked-unbox runtime boundary and refreshed the native-value-profile parity expectation for its intentional POD-copy coverage.
+- Non-callable value-call errors now remain catchable across the checked-unbox runtime boundary; native value profiles now include the intentional POD-copy result.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Describe the shipped stdin behavior instead of the warnings-gate failure.
The phrase “removed a duplicate stdin listener match arm that made current main fail the warnings gate” exposes internal implementation and CI details. State the observable behavior instead, such as end listeners firing after stdin data is consumed.
Proposed wording
-- Kept non-callable value-call errors catchable across the checked-unbox runtime boundary, refreshed the native-value-profile parity expectation for its intentional POD-copy coverage, and removed a duplicate stdin listener match arm that made current `main` fail the warnings gate.

…8881) `echo hi | claude -p "…"` never completes on main. #8861 fixed this by teaching three layers about `end` listeners; the batch landing kept the GC rooting of STDIN_END_CALLBACKS and STDIN_PULL_MODE, but dropped the `"end" | "close"` arm in stdin_on_op — the one that made it work. stdin_on_op is the provider the stdin object's native on/once/addListener delegate to: every registration that is NOT codegen's literal process.stdin.x(…) shape, i.e. an alias or stdin passed as a parameter. Claude Code's print-mode reader is the parameter form — X71(process.stdin, 3000) then stream.once("end", …) inside — so those registrations hit `_ => return` and were discarded, and the end half of its race(once("end"), timeout(3000)) could never win. stdin_off_op gets the mirror arm: #8864 removed the end/close clause from the removal path, so a provider-registered listener could be added but never removed. The two tests that guarded this were dropped with the arm, which is why CI stayed green. Restored, asserting the provider entry points directly rather than through js_readline_stdin_on — the extern path kept working, so it cannot catch this. Sabotage-checked.
