loopd's self-test caught the change (context per slot 131072 -> 262144, slots 2 -> 4). The device tests keep the expectation in one constant, and the M3a script matches it; verify-device passes 6 of 6 and the M3a device check passes. The inference contract notes which M0 findings rest on the old layout and need re-measuring. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
