   drop from the base Job now fails in omninode_infra's own CI, rather than at a production admission
   controller ten minutes into a promotion, which is exactly where it failed on 2026-09-18 when Job
   seed-keycloak-clients reached DeadlineExceeded with zero pods.

+  BOUND TO THE PRODUCT PR, omninode_infra#1580, whose branch this suite was run on. The OCC
+  merge-eligibility gate binds a ticket's evidence to the PR UNDER REVIEW, which for a product-repo PR
+  is that repo's number rather than the OCC companion's. occ-autobind did mint pr-1580 receipts, in
+  OCC#10439, but merged them to this repository's DEV lane, while a hotfix targeting omninode_infra
+  main pins its evidence at OCC MAIN -- the eligibility run on #1580 recorded occ_commit_sha 48414607,
+  main's head. Same ticket, two lanes, two contracts, and the dev-side binding is invisible from the
+  lane being read. This field puts the binding on the lane that is actually pinned.
