The GetCustomerSummary pipeline collected per-order totals via \$addToSet into order_totals subdocuments, then type-asserted each element as bson.M to extract the 'cents' field. Because the assertion always failed silently, lifetime_value_cents stayed at zero even when orders_count was non-zero. Switch from decoding into bson.M and manually type-asserting to decoding into a concrete anonymous struct. The BSON decoder maps field names directly, eliminating the bson.D/bson.M ambiguity entirely. Apply the same pattern to category_spend to fix the favourite-category calculation for the same reason.

After the VU phase Keploy holds all accumulated mocks in memory and needs time to flush them and let GC reclaim enough to drop below the 60 % resume threshold. The previous sleep(5) was too short when a second memory-pressure burst coincided with the start of teardown, leaving the analytics and order-search MySQL mocks uncaptured. Increasing to sleep(20) gives the GC sufficient margin. The teardown order-search loop previously queried per bootstrap customer (customer_id=${customer.id}). Those IDs are derived from emails containing Date.now() + Math.random(); if any customer-creation HTTP mock was dropped during a pressure window (before the syncMock multi-window fix), the mock responses replayed by Keploy could carry different IDs than the recording, making the SQL args non-deterministic across runs. Replacing with five offset-based paginated queries (LIMIT 10 OFFSET 0/10/20/30/40) gives each a fixed, parameter-free SQL text that is identical across every record and replay session.

With the previous 2-minute idle timeout, those connections remained alive through the 20-second teardown sleep and were reused for the analytics and order-search queries. At replay, the keploy replayer serves all accumulated VU-phase SQL commands on the reused connection before reaching the teardown query's SQL, which has no matching mock — causing 6 TCs to fail every run. Reducing SetConnMaxIdleTime to 5s ensures all VU-phase connections time out and are closed within the 20-second teardown window. Teardown queries then open fresh connections with a clean, minimal SQL history that the replayer can match exactly.

Both sides now use the same load profile: go-memory-load (gin-mongo): MIXED_API_VU_STAGE_TARGETS default: [20,40,80,30] → [2,3,4,2] LARGE_PAYLOAD_STAGE_TARGETS default: unchanged (1,2,1) go-memory-load-mysql: MIXED_API_VU_STAGE_TARGETS default: [20,40,80,30] → [2,3,4,2] LARGE_PAYLOAD_STAGE_TARGETS default: unchanged (1,2,1) go-memory-load-mongo: MIXED_API_VU_STAGE_TARGETS default: [20,40,80,30] → [2,3,4,2] LARGE_PAYLOAD_STAGE_TARGETS default: unchanged (1,2,1) go-memory-load-grpc: K6_VUS default: 20 → 3 (constant-vus model) K6_DURATION default: unchanged (120s) Why: keploy/keploy CI's rate-mismatch investigation (PR #4107) proved that the recorder's mock-emit rate at the previous load (~14k mocks/sec peak under 12+ concurrent VUs) exceeded the host CLI's YAML-write disk throughput (~2k/sec) by ~7x. With unbuffered host channels the resulting backlog overflowed kernel TCP buffers on SIGINT (proven: 64% silent loss between agent encode and host decode); with buffered channels the same backlog back-pressured into the application and deadlocked docker compose (proven: 30+ min lane hangs). These memory-load samples are designed to validate that keploy's memory-pressure feature fires across the mysql/mongo/grpc parsers. At 4 peak VUs + 2 concurrent 1 MB large-payload uploads, the agent still spikes memory enough to trigger 2-3 pressure events per run — the load profile the lane was meant to exercise — without overrunning the pipeline's sustainable throughput. The 1 MB LARGE_PAYLOAD ramp is the actual pressure trigger and is deliberately preserved. Local runs (no env overrides) now match the CI defaults. CI env overrides in keploy/keploy track the same values for clarity.
