INFINITO_ARCHITECTURE means two different things. In CI it is the runner's hardware, delivered by `runs-on`. Locally it is the platform app containers are created for, delivered by qemu. The check asserted the first everywhere, so a local run that honoured the assignment by emulation was reported as a mismatch, with an error blaming RUNNERS where nothing was wrong. Each context is now checked against its own promise. On a real runner the uname must match, unchanged. Anywhere else the host must be able to execute the assigned platform, which is verified by running a container of it rather than by reading /proc/sys/fs/binfmt_misc, since that directory reads as empty from a sandboxed shell whether or not a handler is registered. Nothing is skipped and nothing passes quietly. A host that cannot deliver the assigned architecture fails here, in the first second of the job, and names the two commands that fix it. Five arm64 deploys died instead at `exec /bin/sh: exec format error` deep inside an Ansible role, each after fifteen to twenty minutes of setup. This replaces the `exit 0` under act that an earlier version of this change introduced. That version swallowed exactly what this check exists to catch: a row assigned arm64 ran entirely on amd64 and would have reported green. Verified, all four branches: amd64 native passes; arm64 with emulation present passes as emulated; arm64 without it exits 1 with the remedy; a real-CI mismatch exits 1 with the RUNNERS hint. shellcheck clean.
