syntaqxA workspace runs up to 12 jobs at once on g1t's machines while the pool has room, not 4. Every workspace was held to 4 hosted jobs at once (RUNNING_PER_WORKSPACE), so flagon-io's own CI and Deploy, about 13 jobs between them, waited their turn: 108 to 518 seconds after their runs were made, for 29aba25d, 58def404 and 0a5d1f6d, though the pool of 40 sandboxes (20 standard, 10 g1t-2core, 10 g1t-4core) was mostly idle. A workspace still always has its 4; past them, start_queued starts more, up to 12 (BURST_PER_WORKSPACE), while every workspace's hosted jobs together leave 8 sandboxes free (POOL_HEADROOM), so another workspace's first jobs still start at once (has_room). Deploy's own concurrency group still lands one deploy at a time. The architecture's Compute limits say so. Checked: cargo test -p g1t-actions-service (115 passing), npm run test:deploy (92).36c7309History
