POST /v1/telemetry/query (a structured, server-validated QuerySpec
scoped to a run and an optional fork-path subtree) — see the quickstart for a
worked example and the API reference for the full schema.Tree-native observability
Telemetry keyed by fork-tree node — observability with the shape of your experiments.
Observability is a first-class citizen in hiloop, not a side channel. Because every piece of
telemetry is tagged with its fork-tree node, observability data has the same
branching shape as your experiments. That lets you ask questions no flat observability stack can
answer — e.g. “show me how the LLM calls diverged between branch A and branch B since their common
ancestor.”
