+### Component: `Blackbox Tests` (cross-cutting)
+
+- **Epic**: AZ-455
+- **Directories**: `tests/` (fast-profile shared helpers, MSW, fixtures, setup), `e2e/` (Playwright config, suite-e2e docker-compose, stubs, runner, e2e specs, e2e fixtures), plus colocated `*.test.{ts,tsx}` and `*.spec.{ts,tsx}` files under any production component directory.
+- **Public API**: none (tests are not consumed by production code).
+- **Internal**: every file under owned paths.
+- **Owns** (exclusive write):
+  - `tests/**`
+  - `e2e/**`
+  - `**/*.test.{ts,tsx}` and `**/*.spec.{ts,tsx}` — colocated test files (Vitest convention) override every production component's `Owns` glob for that filename pattern only.
+  - `vitest.config.ts`, `tsconfig.test.json`
+  - `scripts/run-tests.sh`, `scripts/run-performance-tests.sh` (extension only — the files were created in autodev Step 4 as Step 6 placeholders).
+  - `package.json` test-scoped sections only: `scripts.test*`, `scripts.lint:tests`, `devDependencies` for runners (`vitest`, `@vitest/*`, `@playwright/test`, `msw`, `@testing-library/*`), and any test-only `peerDependencies` overrides.
+  - ESLint test-override blocks (`overrides` entries scoped to `tests/**`, `e2e/**`, `**/*.test.{ts,tsx}`).
+- **Imports from**: `00_foundation` only (and only `src/types/index.ts` — typed wire-contract enums per `_docs/02_document/tests/environment.md` § Black-box discipline / `P9`). NEVER any other production component's internal files. The static profile enforces this via ripgrep.
+- **Consumed by**: (none — tests are not part of production runtime).
+- **Notes**:
+  - Every test task spec under epic AZ-455 carries `**Component**: Blackbox Tests` and resolves its file ownership through this entry.
+  - Colocated test files are OWNED by the test task that creates them, even when the parent directory belongs to a production component. The production files in that same directory remain READ-ONLY for the test task (compile-time imports of the production module under test are permitted; modifications are not).
+  - Test-related `package.json` edits (devDependencies, test scripts) are OWNED here. Production `dependencies` and non-test `scripts` are FORBIDDEN — those remain owned by the production component whose runtime they affect (typically `10_app-shell`).
+  - `mission-planner/` test files (e.g., `mission-planner/src/test/jsonImport.test.ts`) are OWNED here for the same reason; the `mission-planner/**` production glob remains owned by `05_flights`.

 ## Shared / Cross-Cutting

 Violations of this table are **Architecture** findings in code-review Phase 7 and are High severity.
 
+The `Blackbox Tests` cross-cutting component sits **outside** this table. It imports from `00_foundation` only (specifically `src/types/index.ts` for typed wire-contract enums) and is consumed by no production component. The static-profile ripgrep checks enforce that no test imports from any other production component's internal files.

 ## Verification Needed
 
 The following inferences could not be made cleanly from code alone. They are surfaced for the user to confirm or override at the Step 2.5 BLOCKING gate.
