Every node the harness starts is a validator, and validators disable pathfinding: Config.cpp:725-726 zeroes pathSearchMax whenever a [validation_seed] or [validator_token] section is present, and run-full-validation.sh writes [validation_seed] into every generated node cfg (:308) with no [path_search] section to put the default back. So doRipplePathFind refused every call at RipplePathFind.cpp:48-49 and the 3% ripple_path_find weight bought no coverage at all. It was not free either. The pathfind.request guard is constructed at RipplePathFind.cpp:35, above that refusal, so each refused call still exported a span, and the enclosing rpc.command.ripple_path_find span carried rpc_status=error. That put a steady 3% error floor into span_calls_total for STATUS_CODE_ERROR: any error-rate threshold derived from harness data before this change was measuring the harness rather than xrpld, and needs re-deriving. Removing the load makes pathfind.request unreachable, so it moves from required to optional in expected_spans.json; without that the span check would fail on every run. Three notes in that file and three in expected_metrics.json made claims that are now false, two of them citing line numbers this commit deletes; all six are corrected. The runbook required/optional count moves 26/15 to 25/16. Two facts a future reader needs. First, the weights previously summed to 103, not 100, so every percentage the docstring stated was wrong: health checks were really 38.8%, not 40%. Dropping the 3 makes the sum exactly 100 and every stated percentage correct for the first time. expected_spans.json also carried live arithmetic off the old total, "25/103 ... roughly 43%", now 25/100 and 42%. Second, baselines/baseline-timings.json was captured WITH this load. Only span.rpc.ws_message p50/p95/p99 of the 25 gated keys sees the RPC mix, and their trip points sit 3.1x to 5.9x above baseline, so the gate will not fire. But a timing baseline is workload-specific and its profile field still reads full-validation, so nothing will flag the drift: refresh it from the next CI run's timings artifact. Pathfinding now has no coverage in this harness at all. The workload README section "Pathfinding is not exercised" records that cost, the manual verification route, and a four-step restore recipe in which steps 1 and 2 alone only reinstate the error floor.
