The temporary [sio-in] / [sio-out] / [ws-rx-text] / [ws-rx-bin] /
[ws-recv-exit] / [ws-loop-exit] logs added during the hand-ack
investigation are useful enough to keep around (PvP testing, future WS
debugging) but too chatty to leave on by default. Promote them from
"strip before merge" to a permanent opt-in.
New BattleNodeOptions.DiagnosticLogging (bool, default false). Wired
through BattleNodeWebSocketHandler to RealParticipant via a new optional
ctor parameter (default false — existing test sites pick up the silent
default with no changes). Every Information/Warning log added during the
investigation is now if-gated; non-diagnostic logs (the decode-failure
warnings, the dispatch-drop debug) stay as-is.
Toggle via appsettings*.json:
"BattleNode": { "DiagnosticLogging": true }
Or live via the singleton:
factory.Services.GetRequiredService<BattleNodeOptions>().DiagnosticLogging = true
175 battle-node tests still passing — existing tests use the constructor
default and emit nothing, so no test changes were required.
