+# User Testing
+
+Testing surface, tools, setup steps, and known quirks.
+
+**What belongs here:** how validators/workers should exercise the user-facing surface.
+
+---
+
+## Primary Surface
+
+- CLI commands:
+  - `ui-test record`
+  - `ui-test improve --plan`
+  - `ui-test improve --apply-plan`
+  - `ui-test play`
+
+## Preferred Validation Path
+
+1. Use focused Vitest coverage for record/improve behavior.
+2. Use `src/core/improve/improve.dynamic.integration.test.ts` for brittle-fixture repair proof.
+3. Use `src/core/player.integration.test.ts` plus `scripts/run-headed-parity.test.mjs` for parity coverage.
+4. Final gate: `npm run test:parity:headed`.
+
+## Constraints
+
+- Do not use live external websites as proof of determinism.
+- Prefer controlled local fixtures and ephemeral localhost servers created by tests.
+- Optional manual slice may use the example app on `127.0.0.1:5173` only if needed.
+
+## Flow Validator Guidance: CLI
+
+- Run CLI validations in isolated temp directories (`mktemp -d`) to avoid file collisions between parallel validators.
+- Use unique filename prefixes per validator (for example `flow-a-*`, `flow-b-*`) for plan/report/output artifacts.
+- Do not reuse another validator's generated plan, report, or YAML output paths.
+- Keep execution local and deterministic: use repository fixtures/tests only; never use external websites.
+- Prefer `vitest run <target files>` coverage that directly maps to assigned assertions.
+
+## Known Validation Quirks
+
+- `improve` runtime treats `data:` navigation URLs as relative and reports `Cannot resolve relative navigation URL`; this can be used as deterministic runtime-failure evidence in candidate-skip assertions.
+- If transient local TypeScript worktree errors block `npm run build`, validators may use the existing `dist/bin/ui-test.js` binary for CLI-flow checks.
+- Vitest in this repo only runs tests under configured include globs; ad-hoc validator test files created under `/tmp` will be ignored. Place any temporary flow tests under `scripts/` (with unique prefixes) if dynamic test generation is needed.
