test: mutation testing (security libs) + SSE load harness, on-demand
Two on-demand depth tools, neither a merge gate: - Stryker mutation testing scoped to the security-critical backend libs (access.ts, downloadTokens.ts, safeError.ts, chat/citations.ts). Measured 74.0-76.4% mutation score across runs; thresholds.break=69 fails only on real regressions. `npm run test:mutation` locally (~3 min), .github/workflows/mutation.yml on demand + monthly cron, HTML report uploaded as artifact. - k6 load harness for the SSE chat stream (loadtest/sse-stream.js): ramps to N concurrent POST /chat streams, checks TTFB and that every stream delivers events through to the [DONE] sentinel - the past incident class (streams timing out on long tool calls). Lenient, documented thresholds. .github/workflows/loadtest.yml is workflow_dispatch-only and boots nothing: point it at a staging stack (PR #210). docs/test-depth.md explains how to read the mutation report, how to run the k6 harness against the local stack, and why neither gates merges.
