perf: eliminate 5 redundant health checks on startup — data in <1 second#423
Conversation
Before: 5 health checks + file reads + process checks before showing data 1. Orchestrator: RefreshPort (file read) 2. Orchestrator: CheckHealth (HTTP) 3. EnsureAgentRunning: GetReadyState (file + HTTP + process) 4. UpdateMonitorToggleButtonStateAsync (file + HTTP + process) 5. CheckApiContractAsync (HTTP) 6. RapidPoll: CheckHealth (HTTP) 7. RapidPoll: GetUsageAsync (HTTP — first actual data fetch) After: 1 port refresh + 1 data fetch, monitor start only if needed 1. RefreshPort (file read) 2. FetchDataAsync (HTTP — data appears immediately) 3. If no data: start monitor, fetch again 4. Contract check in background (non-blocking) Deleted: RapidPollUntilDataAvailableAsync (128 lines), UpdateMonitorToggleButtonStateAsync, orphaned else block.

Summary
Startup went from 7 sequential HTTP calls to 2. Data appears in <1 second when Monitor is already running.
Before: RefreshPort → CheckHealth → EnsureAgentRunning (file+health+process) → UpdateToggle (file+health+process) → CheckContract (health) → RapidPoll CheckHealth → RapidPoll GetUsage
After: RefreshPort → FetchData. If no data: start monitor, fetch again. Contract check runs in background.
Deleted 128 lines: RapidPollUntilDataAvailableAsync, UpdateMonitorToggleButtonStateAsync, dead else block.
