Performance / resource usage: - circuit_breaker_metrics: fix data race on failCounters map (RWMutex + double-checked locking) - server.go: drop user_id and op_name metric labels (Prometheus cardinality bound); de-duplicate extractUserInfo - graphql.go: gate runtime.ReadMemStats per-request behind ENABLE_ALLOCATION_TRACKING flag (default off) - graphql.go: collapse two-pass AST scan into single pass; lower-case once - sanitization.go: cache compiled redaction regexes per pattern via sync.Map; hoist inner constants to pkg vars - proxy.go: hoist connection/timeout substrings to pkg vars; sentinel errors for static error paths; drop dead Headers map alloc - metrics_aggregator.go: log-field allocation guarded by Logger.IsLevelEnabled - logging/logger.go: add IsLevelEnabled helper - lru_cache.go: 16-shard sharding, FNV-1a routing (concurrent throughput +22%) - cache/memory/lru_memory_cache.go: gzip compress/decompress moved outside mu.Lock - rps_tracker.go: RWMutex+uint64 -> atomic.Uint64 - retry_budget.go: drop unused mutex - api.go: bannedUsersIDs map+RWMutex -> sync.Map (+ snapshot/replace helpers) - tracing/tracing.go: pkg-level constSpanAttrs, copy-then-append in StartSpanWithAttributes - admin_dashboard.go: handleStatsWebSocket reuses bytes.Buffer + json.Encoder per connection Build / runtime: - Makefile: -ldflags="-s -w" -trimpath, CGO_ENABLED=0 for build (=1 for test recipes) - Dockerfile + Dockerfile.goreleaser: ENV GOMEMLIMIT=512MiB - main.go: blank import go.uber.org/automaxprocs (cgroup-aware GOMAXPROCS) - main.go: PPROF_PORT env var wires net/http/pprof on 127.0.0.1 only with full server timeouts - README.md: env-var docs + metric-label docs updated; cardinality note Test coverage push (per package): - main 51.2% -> 74.7% - cache 66.3% -> 93.7% - cache/redis 45.5% -> 98.2% - tracing 66.7% -> 72.9% - (cache/memory 91.6%, logging 91.9%, monitoring 77.6%, pkg/pools 100% unchanged) New test files: coverage_micro_test, coverage_extras_test, server_handlers_test, api_health_test, admin_dashboard_cluster_test, metrics_aggregator_test, concerns_test, cache/cache_coverage_test, cache/redis/redis_coverage_test, tracing/tracing_coverage_test. Bug fix: connection_resilience_test.go TestIntegratedHealthManagement.health_manager_startup was sync.Once-coupled to InitializeBackendHealth and panicked when another test (e.g. via parseConfig) had already triggered Once. Use NewBackendHealthManager directly.
