+# Endpoints publishes its own seeds on its own rotation, independent of the

+# every two cohorts, each set adoptable for four. A submission binds to one set
+# and keeps it for its full Pareto-update window. Values are transcribed

+# The cohort ID and set ID are both carried in the version string: `seed_sets`
+# is a list keyed by `id`, so a cohort may publish more than one set, and the

+# cohort — adds a sibling round rather than editing this one. Endpoints
+# characterizes a Pareto curve rather than gating per-model TTFT/TPOT, so there
+# are no per-model rulesets to declare: this round exists to pin seeds, and the
+# legacy per-model `apply_user_config` path correctly refuses it.

+# only in seedset.yaml, which gives no definition. Submission rules §4.6 says
+# the set drives "request-issue / sample order, and the per-query salt"; this
+# round maps the first two, leaving the salt RNG unaccounted for. Pinning the
