# Alpha 50.9.17 Changeset

## Scope

Fixes the staging-only Telegram delivery failure discovered after `v0.4.0-alpha.50.9.16`. The PNG renderer successfully produced a valid 1000x1000 PNG, but `sendPhoto` failed because structured multipart fields such as `reply_markup` were coerced with `String(value)`, producing `[object Object]`.

## Changes

- Serialize object-valued multipart fields with `JSON.stringify`.
- Keep scalar multipart fields as strings.
- Add a regression test covering structured multipart fields used by Chat Mandala PNG delivery.
- Version: `0.4.0-alpha.50.9.17`.

## QA expectation

`/status` must deliver the rendered Chat Mandala as an inline PNG with its localized caption and inline keyboard. The same path is used for final Chat Mandala delivery.
