It uses the listing for routing slots and capacity, with configured slots or snapshot data as fallbacks. ChangesE2E Runner Routing
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: ⚪ Minimal · up to E2E routing now uses live runner labels when available and retains its fallbacks if listing fails. No new issue warrants blocking this change; the known GUI-demand concern is on a separate, unchanged path. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to Live runner availability can now change where E2E jobs run, but routing remains limited to enabled, Xcode-matched owned pools. Listing failures retain configured routing. No introduced security bypass was established; runner-label governance and production behavior remain unverified.

Calculate root demand for each candidate pool.
gui_runners is computed from all routing labels before choose() selects a pool. If only the light pool has a GUI label, root_peak(plan, gui, gui_runners) can exclude GUI-token jobs from the standard pool’s root demand. place() then checks the selected pool’s own GUI label. For a standard-pool pick without that label, those jobs can exceed the pool’s root budget and route to Blacksmith.
Calculate root demand with GUI availability for each candidate pool before selecting the pool.

…D_POOL_SLOTS e2e_runner_pool.py read the runners live for capacity but still let the variable decide whether an owned pool and its root label route. main() now lists the runners once and passes pr_runner_pool.routing_slots() when the listing succeeds; the variable stays the fallback without it.

Stacked on #15572 (uses its
pr_runner_pool.routing_slots()); merge that first, this PR's diff then shrinks to the E2E picker.Change
e2e_runner_pool.pyalready took owned capacity from the runners API, butCI_OWNED_POOL_SLOTSstill decided whether an owned pool and its root label route (ui_owned_runner(), the named-pool root rewrite,auto_runner()'s slots).main()now lists the runners once (read_live_runners(), reused bymeasure()so there is no extra API call) and passesrouting_slots(), the online runners per pool/root label, when the listing succeeds. Without a listing (no route token, e.g. a namedrunnerinput, or an API error) the variable decides as before.Routing order is unchanged: minis first, Blacksmith overflow.
