Function-form `manualChunks` is called but its assignments are silently discarded (Vite 8 / rolldown) — lazy chunk pulled onto the boot path

Important limitations

• This may be one public report, not widespread demand.
• Current independent report count: 1.
• This is currently a single independent report. It has not passed clustering or human review as a verified signal.
• No market size, willingness to pay, competition, or trend claims are inferred here.

What was reported

Who is affected

Application developer using the reported software

Job to be done

Maintain runtime module identity while bundling

Workflow

Concrete failure: a shared CJS module that the function assigns to a static chunk is instead colocated into the chunk of its dynamic-only CJS requirer.

Desired outcome

The [v8 migration guide](https://vite.dev/guide/migration) says the object form is removed and the function form is *deprecated* — deprecated, however, should mean "works with a warning", not "accepted and ignored with no warning".

Severity

Not enough evidence yet.

Urgency

Not enough evidence yet.

Evidence indicators

What would upgrade this

• Additional independent reports from distinct communities or authors.
• Human clustering into a review signal, then explicit publication approval.
• Counter-evidence review and durable original-source verification.
