// StatusReport is the ALLOWLISTED subset of `tmctl status --json` (pipeline.StatusReport) that the
// platform materializes. Everything absent here is absent on purpose: snapshot ids, drift, rebill,
// routing, content labels and the operator's flag taxonomy are engine vocabulary that must not
// cross the seam (contract §2.12), and unknown JSON fields are simply ignored by encoding/json.
//
// ⚠ Limit worth knowing: status has no PHASE split (engine backlog row 99). A resync can therefore
// restore the aggregate counter but not "draft N/M ∥ edit N/M"; the phase split lives only in the
// stream until row 99 lands. A reconciled run shows the aggregate until its next progress event.

// projected into an API response or an INFO log (D39.84).
// A POINTER: absent, null and empty must not read as "the attempt cost nothing". A settlement
// computed from a missing figure would release the whole hold and charge zero.
