Two entries in the span contract could fail on healthy behaviour. `ledger.serve` is emitted when this node answers another node's request for ledger data, and was mandatory. A node only answers if a peer asks, and a `TMGetLedger` request is constructed in exactly two places -- src/xrpld/app/ledger/detail/InboundLedger.cpp and src/xrpld/app/ledger/detail/TransactionAcquire.cpp -- whose `ledger.acquire` and `txset.acquire` spans are both already marked optional. A mandatory check therefore rested on an optional cause. Marked optional, with the dependency named in the note so it is promoted together with them rather than alone. `peer.dial` covers one outbound connect attempt and required `outcome` and `duration_ms`. Both are set only in `reportOutcome()` (ConnectAttempt.cpp:158-199). The teardown path sets neither on purpose: an attempt destroyed during overlay shutdown, or one whose connect was aborted, ends its span in `~ConnectAttempt` (ConnectAttempt.cpp:89-102), whose own comment states that a span ending with no `outcome` is the honest record of a dial that never concluded. Since `peer.dial` is a freshRoot, each dial is its own trace with exactly one instance of the span, and the validator inspects only the most recent trace -- so one newly-aborted dial fails CI while the node is behaving correctly. `remote_endpoint` stays required; it is set at construction on every path. Verified: both call sites read in current code; `TMGetLedger` construction confined to those two files; the counters recomputed -- 48 span types (matches len(spans)) and 74 unique attributes, unchanged, because `outcome` and `duration_ms` are still required by `txset.acquire` and the `ledger.acquire` family. Not verified: that a run with these entries relaxed still exercises both spans, which only a CI dispatch can show. Neither entry can now fail on healthy behaviour, so a green run proves less than before by design.
