The scheduled canary runs the full matrix on all versions and is by far the most expensive run type. AMD ran 4x/day and ARM 8x/day; halving AMD alone saves ~1,900 compute-h / 2 weeks (~6% of AMD CI), and cutting ARM 8->2/day removes 75% of the ARM canary schedule. The two crons are interleaved (AMD 01:58 & 13:58, ARM 07:28 & 19:28) so a full-matrix canary still runs roughly every ~6h, alternating architecture - so the 'trust earned on main' backstop keeps a ~6h effective cadence for arch-agnostic regressions (12h for arch-specific ones) while the scheduled compute drops substantially. It also relieves runner-pool queuing, since each canary is the heaviest job-flood. check_ci_workflows_in_sync.py expected blocks updated to match.
