attempts/successes/failures summed over the range. failures is
broken down by the closed failure_reason enum negotiation.Negotiate
actually produces (version_unsupported,
capabilities_incompatible); each carries
missing_capability_counts when the failure reason is itself a
capability-set delta (capabilities_incompatible only —
version_unsupported fails on the version field, not a capability
delta, so that map is absent there). payment_handler_mismatch is
its own dedicated breakdown, computed observationally from every
negotiation attempt (succeeded or failed) whose offered
payment-handler set had no overlap with the merchant's declared
set — an empty payment-handler intersection does not fail
negotiation on its own, so this condition would otherwise be
invisible in `failures`. Breakdown entries below the small-count
suppression threshold (default 5) are omitted; attempts/successes
totals are never suppressed. Max range 92 days.
