- Drop xrpl.node.amendment_blocked / xrpl.node.server_state from telemetry surface (constants in SpanNames.h, two filters in tempo.yaml). Operators read the same data via server_info / server_state RPC; OTel SDK 1.18.0 cannot refresh resource attrs at runtime so resource-level emission was not viable either. - Namespace all pathfind span attributes under pathfind_* (underscore form per Phase 1c rule 5). Renames in PathFindSpanNames.h and call sites in PathRequest.cpp, PathRequestManager.cpp, plus the rule-5 retention xrpl.pathfind.ledger_index -> pathfind_ledger_index. - Wire pathfind_source_account / pathfind_dest_account on pathfind.request in doPathFind / doRipplePathFind handlers (only when present + string). - Collapse per-asset pathfind.discover / pathfind.rank spans into one pathfind.discover hoisted around the per-source-asset loop in PathRequest::findPaths. Span count goes from 2N to 1 per RPC call; per-asset breakdown traded for bounded storage and cardinality. Trade-off documented inline. - Fix pathfind_num_paths semantics: now sums getBestPaths().size() across the loop (paths actually returned) instead of the maxPaths input cap. - PathRequestManager::updateAll: move span creation after the locked requests_ snapshot, early-return when no active subscriptions exist (avoids empty span on every ledger close), set pathfind_num_requests = requests.size(). - Update Phase2_taskList.md and 02-design-decisions.md to match.
