#get_span_tree(external_span_id) ⇒ Object

Fetch the span tree rooted at an external span. Blocking GET request. Used by replay when a mock strategy is active so child spans can be matched against their historical outputs.

Returns a hash shaped { “root” => SpanTreeNode } where each node has sourceSpanId, traceFunctionKey, spanName, type, output, optional outputMeta, and children.

#release_db_branch_lease(neon_branch_id) ⇒ Object

Release a previously-resolved DB branch by deleting its Neon branch. Blocking call. Idempotent server-side (a missing branch is treated as already released).

Start a replay session by fetching historical traces. Blocking call. Returns hash with testRunId, testRunUrl, and items array.

Parameters:

  • code_change_description (String, nil) (defaults to: nil)

    optional rationale for the code change being tested in this replay

  • code_change_files (Array<Hash>, nil) (defaults to: nil)

    optional list of edited files, each as { path:, before:, after: } (use “” for new/deleted files)

  • experiment_group_id (String, nil) (defaults to: nil)

    optional UUID grouping multiple replay runs into a single experiment batch

  • name (String, nil) (defaults to: nil)

    optional display name for the resulting experiment/test run

  • dataset_id (String, nil) (defaults to: nil)

    optional UUID of the dataset this replay runs against, stored on the resulting experiment for durable attribution
