* fix(relay-ops): keep one stalled director instance from tripping the reserve watch's 503 rule The reserve watch's director503 rule counted fleet-wide non-drain 503s. On 10-21 07:55Z one director instance's database calls stalled for 3 minutes; its 503s alone carried the fleet over the line and all four watched cells flipped back to db. Over the fleet line the rule now also needs at least 2 director instances each above a fifth of it for the same 3 minutes, counted from Cloud Run's request log by labels.instanceId less each instance's scheduled 503s. Above max(10x background, 200) for 3 minutes it trips with no split. * fix(relay-ops): size the instance share to the directors seen and count platform 503s * fix(relay-ops): size the instance share per judged minute and refuse a missing count
