CORRECTED 2026-08-23 — A §3 STALE-CITATION REPAIR, AND THE CLASS IS A REFUSAL REASON THAT OUTLIVED ITS CAUSE. What stood here said the operator had supplied the router table but never stated the assignment, so authoring `srv5-host-lan` at one of those addresses would be a 50/50 guess about which physical machine a fleet subject names and therefore a §5 fabrication. THAT REASON IS FALSE, AND IT IS FALSIFIED TWICE OVER. First by its own cited authority: gunbc.spark.dgx_procurement `dgx_spark_router_binding_operator_allocation` records the assignment as decided 2026-08-07 under explicit operator delegation ('the 5, 6 decision is arbitrary - just make it yourself'), and both `srv5_router_binding` and `srv6_router_binding` are SlotAssigned — so the reservations are no longer unassigned router facts, which is what the sentence above assumed when it wrote them off as such. Second, and more decisively, BY A DERIVATION THAT HAS EXISTED FOR MONTHS: gunbc.fleet_reach_endpoint `spark_endpoint_for_binding` already projects an assigned binding to its reservation address, and `fleet_probe_endpoint_for` already resolves srv5/srv6 to .222/.223 through it — so the guess this annotation forbids was never the only option, and the fleet has been addressing both Sparks by their modeled reservation the whole time this text claimed it could not safely be done. The lesson is the one the correction itself teaches: a reason that outlives its cause is worse than no reason, because the next reader takes it as a live constraint and declines work that is unblocked — which is exactly what it cost before this repair. WHAT IS STILL TRUE, STATED SO THIS DOES NOT BECOME THE NEXT DEAD REASON: srv5/srv6 STILL DO NOT APPEAR IN `endpoints` BELOW, and the reason is now enrollment rather than addressing. Reach addressing and fleet membership are different fact classes — gunbc.spark.dgx_procurement's SPARK-0 annotation already says a reserved identity is explicitly not enrollment. Addressability is a property of the router reservation and is true today; MEMBERSHIP FOLLOWS PROVISIONING AND NEVER PRECEDES IT, and the two units are 0/2 provisioned BY DELIBERATE OPERATOR ACTION. An endpoint row here would assert fleet membership for two machines the operator has deliberately not stood up — a fabricated-state claim of the same family as a fabricated address, one level up. So this row is blocked on the operator, not on the model, and it dissolves when the units are provisioned rather than when some fact is recovered. data operator_host_srv5: HostIdentity = "srv5" data operator_host_srv6: HostIdentity = "srv6" diff --git a/dag/gunbc/fleet_reach_endpoint.dag b/dag/gunbc/fleet_reach_endpoint.dag index e09e8366da4..5992315adad 100644 --- a/dag/gunbc/fleet_reach_endpoint.dag +++ b/dag/gunbc/fleet_reach_endpoint.dag @@ -6,6 +6,7 @@ import gunbc.spark.dgx_procurement { DgxSparkRouterBinding, SlotAssigned, SlotUnassigned, + router_binding_identity, dgx_spark_router_bindings, } import extdeps.network.ipv4 { render_ipv4_address } @@ -31,16 +32,28 @@ fn spark_endpoint_for_binding(binding: DgxSparkRouterBinding) -> String? { // Fleet-wide: a host with a modeled endpoint probes AT that endpoint; every other host // probes by name (srv1-srv4 resolve via the LAN today).
