Fix memory failures in large multipart uploads

Runtime changes often expose assumptions hidden in ordinary request paths.

A narrow fix can restore reliability while broader compatibility expectations remain intact.

Our UI says the upload worked, then the request just disappears.

What pulls against what

  • fast mitigation vs. root-cause repair
  • streaming efficiency vs. compatibility
  • upload completion vs. resource limits

What is at stake

A focused runtime regression is interrupting real customer submissions. A verified fix quickly restores a visible workflow

Why Vercel

At Vercel, this can matter because application delivery often depends on request handling that remains predictable under varied traffic.

This is the setup. The work is inside.

Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
