Server after b0a5ce6: load 9.8 (was 12.4), no slow API requests after 16:42, but copy detection still 111 s (BSC) / 64 s (Robinhood) median and three long statements in pg_stat_activity. - Copy engine: the launchpad adapter refresh read every token of every launchpad (15 s) every 60 s inside the watch loop. Now a full read on start and hourly, otherwise only tokens created or traded since the last refresh (both columns indexed). - Migration 0043: index evm_tokens (chain, safety_at) for data-evm's entry pass (49 s), CONCURRENTLY. - ml: the missed-winner query (108 s) runs every 6 hours instead of every 30-minute cycle; its rows are written once each. - db_health: age of the newest stored EVM trade and each scan cursor, to tell feed lag from copy-engine lag. - Audit report section X.

…ce view The 2 GB / 2 vCPU droplet (16 GB database) ran at load 8-12 with 345 MB free and 1.3 GB swap. Keep the trading core reliable on it; nothing is deleted and Solana execution is unchanged. - SYSTEM_RESOURCE_MODE (NORMAL / LOW_RESOURCE / EMERGENCY, default LOW_RESOURCE) and COPY_TRADING_STATUS (ACTIVE / THROTTLED / SUSPENDED, default SUSPENDED), changeable from the dashboard (yonixalpha_core.operating_mode). - Resource level NORMAL / WARNING / CRITICAL from /proc with configurable thresholds (yonixalpha_core.resources); CRITICAL pauses priority-3 work only. - Copy engine: SUSPENDED stops target watching, copy entries, outcomes, wallet profiles and enrichment, and keeps managing open copy positions; THROTTLED watches less often. Step timers start due on the first pass. - ml: training once a day in LOW_RESOURCE and never while CRITICAL (recorded as SKIPPED with the reason); wallet ML pauses with copy trading. Inference is unaffected. - ML Review: review_status CURRENT / STALE / RUNNING / PENDING / FAILED, 202 with no result, automatic refreshes deferred while CRITICAL, explicit Refresh button. - API: GET /system/resources, PUT /system/resource-mode, GET/POST /copy/trading-status (resume refused unless the COPY_* thresholds hold; audited). - UI: Server resources panel on System Health, copy-trading status banner with the resume check, review status lines. - Heartbeats carry CPU seconds; worker DB pools 5 + 10 (API 10 + 10). - Postgres (prod): explicit defaults, effective_cache_size 512MB, no parallel workers, jit off. - db_health: mode, per-service memory / CPU, Redis, Solana pipeline latency. - docs/LOW_RESOURCE_MODE.md: pre-deploy report, changes, PR #56, staged rollout, after-deploy table, 8 GB values.

Changes
refresh_adaptersused to read every token of every launchpad every 60 s, inside the watch loop, so target trades waited behind it. It now does a full read on start and once an hour. In between it reads only tokens created or traded since the last refresh (restore_adapter(since=...), both columns indexed).evm_tokens (chain, safety_at), built CONCURRENTLY.build_missedruns every 6 hours instead of every 30-minute cycle. MISSED rows are written once each, so no row is lost.Tests
