- gateway-metrics: collectors now run per scrape so Prometheus sees real data (process memory/uptime + live AI-analysis pipeline gauges) instead of an always-empty stub. bootstrap registers the pipeline collectors. - systemd: MemoryMax 512M -> 1G (live RSS ~500MiB, peak 508MiB; 512M left ~2% headroom and risked an OOM-kill restart; host has 8GB free). - config: POSTGRES_POOL_MIN 2 -> 0 so main + 4 Piscina worker threads don't hold ~10 permanently-open idle pg connections against PgBouncer. - docs: rewrite stale ARCHITECTURE.md / MODULE_STRUCTURE.md (winston -> pino, removed mock-crc/indonesianTextNormalizer, renamed aiAnalysisWorker/llmModerationClient). Verified: tsc clean, 129 vitest pass, biome clean on changed files. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
