- loadtest/REPORT-R7.md: the final stress-run report — method, the 500-player resource
profile, the agreed tuning, the validation (transport_error 2.49% -> 0.72% at 3 gateway
cores; the burst run showing connection-bound behavior), and the prod-sizing
recommendation for Stage 18.
- loadtest/README.md: per-player transports, --cpus capping, docker_stats (was cAdvisor),
the absolute BACKEND_DICT_DIR for ./loadtest/... , and report links.
- docs/TESTING.md + docs/ARCHITECTURE.md: observability now uses the otelcol docker_stats
receiver (cAdvisor removed); links to both trip reports.
- CLAUDE.md: repo-layout line reflects docker_stats + per-service limits.
- PRERELEASE.md: R7 marked done in the tracker + heading; a Refinements entry recording
the decisions, findings, applied tuning and validation.
This is the final pre-release hardening phase; Stage 18 (prod cutover) is next.
