 $ARGUMENTS
 ```
-You **MUST** consider the user input before proceeding (if not empty).
+You **MUST** consider the user input before proceeding (if not empty). User may specify a subset of files or a specific scope override.
 ## Goal
-Run the verification loop for the touched ss-tools scope: semantic audit, decision-memory audit, executable tests, logic review, and documentation of coverage/results.
+Run the full verification loop for the touched ss-tools scope:
 1. **Mocking discipline audit** — scan every test file in scope, classify every mock/spy/stub/patch, flag violations
 2. **Auto-fix violations** — correct SUT mocks and Logic Mirrors (no flag needed; fix by default)
 3. **Semantic audit** — contract density, belief runtime, rejected-path regression
 4. **Executable tests** — run pytest + vitest + lint
 5. **Documentation** — mock audit report + coverage summary + ADR guardrail status
 ## Operating Constraints
-1. **NEVER delete existing tests** unless the user explicitly requests removal.
+### Golden Rules (from `semantics-testing` skill)
-2. **NEVER duplicate tests** when existing test coverage already validates the same contract.
+1. **Mock only `[EXT:...]`** — external boundaries (DB drivers, HTTP clients, file I/O, third-party APIs).
-3. **Decision-memory regression guard**: tests and audits must not silently normalize any path documented as rejected.
+2. **NEVER mock the SUT** — the production `#region` contract you are actively verifying.
-4. **Project-native structure**: prefer existing test organization — `backend/tests/` for Python, `frontend/src/lib/**/__tests__/` for Svelte.
+3. **Anti-Tautology (Logic Mirror) is forbidden** — never compute `expected_result` by repeating the production algorithm inside the test.
 4. **Global DOM mocks are infrastructure, not logic** — `ResizeObserver`, `scrollTo`, `IntersectionObserver` in `vitest.setup.ts` or `setupTests.ts` are **not violations**.
 ### Additional Constraints
 5. **NEVER delete existing tests** unless the user explicitly requests removal.
 6. **NEVER duplicate tests** when existing test coverage already validates the same contract.
 7. **Decision-memory regression guard**: tests and audits must not silently normalize any path documented as rejected (`@REJECTED`, ADR guardrails).
 8. **Project-native structure**: prefer existing test organization — `backend/tests/` for Python, `frontend/src/lib/**/__tests__/` for Svelte.

 - `skill({name="semantics-testing"})`
 - `skill({name="semantics-core"})`
 - `skill({name="semantics-contracts"})`

-Before writing or executing tests, perform a semantic audit of the touched scope:
+| Layer | Patterns |
 |-------|----------|
 | Backend unit | `backend/tests/**/*.py` |
 | Backend integration | `backend/tests/integration/**/*.py` |
 | Frontend unit | `frontend/src/**/*.test.ts`, `frontend/src/**/__tests__/*.ts` |
 | Frontend integration | `frontend/src/**/*.integration.test.ts` |
 | Frontend UX | `frontend/src/**/*.ux.test.ts` |
 | Frontend component | `frontend/src/**/__tests__/*.svelte.js` |
 #### 3b. Extract Per-Test Metadata
 For each test file:
 - Which production `#region` contracts it references — look for `@RELATION BINDS_TO`, `@TEST_INVARIANT`, or import paths to production modules. Discover contract IDs via `axiom_semantic_discovery read_outline` on production files.
 - All mock/patch/stub/spy declarations (`unittest.mock.patch`, `unittest.mock.MagicMock`, `pytest.monkeypatch`, `vi.mock`, `vi.fn`, `vi.spyOn`, `mockResolvedValue`, etc.)
 - Whether the file is a **global setup** file (`conftest.py`, `vitest.setup.ts`, `setupTests.ts`)
 #### 3c. Classify Every Mock
 Apply this classification table **to every mock found**:
 | Mock target | Verdict | Rule |
 |------------|---------|------|
 | `[EXT:Database]`, `[EXT:HTTP]`, `[EXT:File]`, `[EXT:ThirdParty]` | ✅ VALID | External boundary — allowed |
 | `localStorage`, `fetch`, `fs.readFileSync`, `os.environ` | ✅ VALID | External API / I/O — allowed |
 | `Date.now`, `Math.random`, `uuid.v4` | ✅ VALID | Non-deterministic input — allowed |
 | `ResizeObserver`, `IntersectionObserver`, `scrollTo`, `matchMedia` in global setup | ✅ VALID | DOM infrastructure — allowed |
 | `ResizeObserver`, `IntersectionObserver` in individual test file (not setup) | ✅ VALID | DOM environment polyfill — allowed |
 | `AuthService` (the `#region` production contract under test) | ❌ VIOLATION | Mocking SUT — forbidden |
 | `GitPlugin` (the `#region` production contract under test) | ❌ VIOLATION | Mocking SUT — forbidden |
 | `MigrationEngine` (the `#region` production contract under test) | ❌ VIOLATION | Mocking SUT — forbidden |
 | Database session/repo when it IS the integration boundary under test | ❌ VIOLATION | Mocking SUT in integration test |
 | Test computes `expected = a + b` to test `add(a, b)` | ❌ VIOLATION | Logic Mirror — tautology |
 | Test computes `expected = production_fn(x)` to test `production_fn` | ❌ VIOLATION | Logic Mirror — tautology |
 | Something unclear, ambiguous ownership | ⚠️ UNCERTAIN | Flag for human review |
 **Do NOT flag as violations**:
 - `@vi.fn` or `vi.spyOn` on callback handlers that are NOT the SUT
 - Mocks in `conftest.py`, `vitest.setup.ts`, `setupTests.ts` that provide shared test infrastructure (DB stubs, browser API stubs, auth fixtures)
 - `MagicMock` / `AsyncMock` used as placeholder arguments that are NOT the SUT
 - `monkeypatch.setenv` for environment configuration (infrastructure, not logic)
 #### 3d. Integration Test Special Handling
 Integration tests have **different mock boundaries** than unit tests. Apply these additional rules:
 | Pattern | Classification | Rationale |
 |---------|---------------|-----------|
 | `TestClient` (FastAPI) / `test_client` fixture | ✅ INFRASTRUCTURE | Test harness, not a mock |
 | Real test database (SQLite `:memory:`, testcontainers PostgreSQL) | ✅ INFRASTRUCTURE | Real dependency for integration fidelity |
 | `conftest.py` DB session fixtures | ✅ INFRASTRUCTURE | Shared test infrastructure |
 | Mocking an **external HTTP API** (e.g., Superset API, Git service) in an integration test | ✅ VALID | External boundary — allowed |
 | Mocking the **application's own router/endpoint** in an integration test | ❌ VIOLATION | Mocking SUT |
 | Mocking the **database layer** in an integration test | ❌ VIOLATION | Defeats purpose of integration test |
 | Full-stack test that mocks the **frontend API client** | ✅ VALID | External boundary from backend perspective |
 | File I/O via `tmp_path` / `tmpdir` fixtures | ✅ INFRASTRUCTURE | Real filesystem, not a mock |
 **Integration test file size limit**: Per `semantics-testing` skill §II.5, integration test files using Testcontainers may be up to **800 lines**. Flag files exceeding this as `⚠️ SIZE` with a recommendation to split.
 #### 3e. Logic Mirror Detection
 For each test assertion, check if the expected value is **computed algorithmically** by mirroring the production code:
 **Python example violation:**
 ```
 # Production: def add(a, b): return a + b
 # Test VIOLATION: expected = a + b   ← algorithmic mirror of production
 ```
 **JavaScript example violation:**
 ```
 // Production: export const formatDate = (d) => d.toISOString().split('T')[0]
 // Test VIOLATION: expect(result).toBe(date.toISOString().split('T')[0])  ← mirror
 ```
 Correct approach: use a **hardcoded fixture** value.
 ```
 expected = 5              # hardcoded, not computed
 expected = "2025-01-15"   # hardcoded, not calling toISOString
 ```
 ### 4. Coverage Matrix
 Build a compact matrix enriched by audit findings:
 | Module / Flow | File | Existing Tests | Complexity | Mock Violations | Guardrails | Needed Verification |
 |---------------|------|----------------|------------|-----------------|------------|---------------------|
 ### 5. Semantic Audit and Logic Review
 Before executing tests, perform a semantic audit of the touched scope:
 1. Reject malformed or pseudo-semantic markup.
 2. Verify contract density matches effective complexity.
 3. Verify C4/C5 Python flows account for belief runtime markers (`reason`, `reflect`, `explore` with JSON structured logging).
 4. Verify C4/C5 Svelte components account for console markers (`[ComponentID][MARKER]`).
 5. Verify no touched code silently restores an ADR- or contract-rejected path.
 6. Emulate the algorithm mentally to ensure `@PRE`, `@POST`, `@INVARIANT`, and declared side effects remain coherent.
 7. **Cross-reference with mock audit**: violations found in step 3 that intersect with semantic contracts must be prioritized.
 If audit fails, emit `[AUDIT_FAIL: semantic_noncompliance | contract_mismatch | logic_mismatch | rejected_path_regression]` with concrete file-based reasons.
-### 5. Test Writing / Updating
+### 6. Fix Violations (Auto-Fix by Default)
-When test additions are needed:
+**Every VIOLATION and Logic Mirror found in step 3 MUST be fixed.** No opt-in flag required — this is the default behavior.
 #### Fixing SUT Mock Violations
 - Replace the mock of the SUT with a **real instantiation** of the production contract
 - If the SUT depends on `[EXT:...]` boundaries, mock ONLY those boundaries, not the SUT itself
 - If instantiation is complex, extract the mocked logic to a separate `#region` contract and test that independently
 #### Fixing Logic Mirror Violations
 - Replace algorithmic expected-value computation with a **hardcoded fixture**
 - Use `@TEST_FIXTURE` to document the fixture source
 - If multiple scenarios need different values, use a parameterized table, not a loop that re-computes
 #### Fixing Integration Test Violations
 - If an integration test mocks the application's database layer, replace with a real test database (SQLite `:memory:` or testcontainers)
 - If an integration test mocks the application's own router, rewrite as a true integration test using `TestClient`
 #### Uncertain Cases
 For `⚠️ UNCERTAIN` flags:
 - Leave the mock in place
 - Add a comment `# AUDIT_NOTE: [YYYY-MM-DD] Flagged as UNCERTAIN — [brief reason]. Review at next test cycle.`
 - List in the report under "Uncertain — Requires Human Review"
 ### 7. Test Writing / Updating
 When test additions are needed (beyond fixing violations):
 - Python: prefer `backend/tests/test_*.py` with pytest
- Svelte: prefer `__tests__/*.test.js` with vitest + @testing-library/svelte
+- Svelte: prefer `__tests__/*.test.ts` with vitest + @testing-library/svelte
- use deterministic fixtures rather than logic mirrors
+- Use deterministic fixtures rather than logic mirrors (see Anti-Tautology rules)
- trace tests back to semantic contracts and ADR guardrails
+- Trace tests back to semantic contracts (`@TEST_INVARIANT`) and ADR guardrails
- add explicit rejected-path regression coverage when the touched scope has a forbidden alternative
+- Add explicit rejected-path regression coverage when the touched scope has a forbidden alternative (`@REJECTED`)
 - **For every C4/C5 flow**: include belief-runtime verification (assert `reason`/`reflect`/`explore` log events)
 For non-UI backend features, UX verification means validating API envelopes, error responses, and recovery messaging promised by `ux_reference.md`.
 For UI features, use browser validation via `chrome-devtools` MCP.
-### 6. Execute Verifiers
+### 8. Execute Verifiers
-Run the smallest truthful verifier set for the touched scope:
+Run the full verification stack for the touched scope:

 python -m ruff check backend/src/ backend/tests/
 cd frontend && npm run lint
 # Frontend
 cd frontend && npm run test
 npm run lint
 npm run build
 ```
 Use narrower test runs when sufficient, then widen verification when finalizing.

 ## Integration Test Boundaries (Reference)
 ### What Integration Tests SHOULD Use (Real)
 | Layer | Real Infrastructure |
 |-------|--------------------|
 | Database | SQLite `:memory:`, testcontainers PostgreSQL, or dedicated test DB |
 | Application Router | `TestClient` (FastAPI), real SvelteKit `app.render()` |
 | File System | `tmp_path` / `tmpdir` fixtures (pytest), real temp directories |
 | Environment | `monkeypatch.setenv` (infrastructure), `.env.test` files |
 | Auth Tokens | Real JWT generation with test secret, or `TestClient` auth headers |
 ### What Integration Tests SHOULD Mock (External)
 | Layer | Mock Strategy |
 |-------|--------------|
 | External HTTP APIs | `responses`, `httpx.MockTransport`, `vi.mock('./api')` |
 | Third-party services (Superset, Git service, LLM providers) | `MagicMock` / `vi.fn` for the client wrapper |
 | WebSocket servers (external) | Mock the connection, not the app's WS handler |
 | Email / notification services | Mock the transport layer |
 ### File Size Limit
 - **600 lines** for unit test files
 - **800 lines** for integration test files (due to longer setup/teardown)
 - Files exceeding these limits SHOULD be split by domain or test class

@BRIEF Test documentation for Gradio Agent Chat (LangGraph) — coverage summary, semantic audit, commands.
 # Test Documentation: Gradio Agent Chat (LangGraph)
 **Feature**: `specs/033-gradio-agent-chat/spec.md`
 **Created**: 2026-06-10
 **Updated**: 2026-06-10
 **Tester**: QA Agent (Verification Loop)

 ## Overview
 Gradio agent backend + Svelte frontend via `@gradio/client submit()`. LangGraph `create_react_agent()` + `interrupt()`/`Command(resume=...)` + `PostgresSaver` + `RunnableWithMessageHistory`. Structured JSON metadata streaming. No REST confirmations, no custom WebSocket.
 **Test Strategy**:
 - [x] Unit Tests (co-located in `__tests__/` directories)
 - [x] Integration Tests (backend API test client)
 - [x] Contract Tests (for API endpoints and semantic contract boundaries)
 - [x] L1 Model Invariant Tests (no DOM render, ~10ms)
 - [x] L2 UX Contract Tests (with `@testing-library/svelte`, ~500ms)
 - [x] Semantic Contract Verification (`@PRE`, `@POST`, `@SIDE_EFFECT`, `@TEST_*`)
 - [x] UX Contract Verification (`@UX_STATE`, `@UX_FEEDBACK`, `@UX_RECOVERY`)
 - [x] Fixture Materialization Tests (JSON fixture structure validation)
 - [ ] E2E Tests (require running Gradio + FastAPI + PostgreSQL)

 ---
 ## Semantic Audit Verdict: PASS
 | Projection | Status | Notes |
 |------------|--------|-------|
 | **P1** Contract Completeness | ✅ PASS | All source files have proper anchors; minor: `AgentChat.Context` missing `@BRIEF`, `AgentChat.Run` missing `@POST` |
 | **P2** Decision-Memory | ✅ PASS | All `@REJECTED` paths documented; regression test for WebSocket rejection exists |
 | **P3** Attention Resilience | ✅ PASS | All anchors pass density rules, hierarchical IDs, <150 line contracts |
 | **P4** Coverage & Traceability | ✅ PASS (with gaps) | 4 new test files added; gaps documented below |
 | **P5** Architecture Realism | ✅ PASS | Tests in correct directories |
 | **P6** Protocol Alignment | ✅ PASS | Canonical syntax used |
 | **P7** Non-Functional | ✅ PASS | Molecular CoT logging in all C4+ code |
 ### Coverage Gaps Remaining
 | Contract | Missing Coverage | Priority | Notes |
 |----------|-----------------|----------|-------|
 | AgentChat.LangGraph.Setup | No direct unit tests | Medium | `create_agent()`, `configure_from_api()` |
 | AgentChat.Context | No direct unit tests | Low | Thin ContextVar wrapper |
 | AgentChat.Middleware | No tests for audit logging | Medium | Async write to assistant_audit is TODO |
 | AgentChat.Panel | No L2 component tests | Low | Integration tests exist |
 | AgentChat.Page | No tests for two-column layout | Low | Simple routing component |
 | AgentChat.ConfirmationCard | Component not yet implemented | Low | Confirmation handled inline in Panel |
 ---
 ## Anti-Patterns & Rules
 ### ✅ DO
 1. Hardcoded fixtures for expected values (no logic mirrors)
 2. External dependency mock at `[EXT:...]` boundaries
 3. L1 model tests without DOM render for invariants
 4. L2 UX tests with `@testing-library/svelte` for visual states
 ### ❌ DON'T
 1. No logic mirrors — fixtures use INLINE_JSON or file paths
 2. No WebSocket imports in frontend model (regression-tested)
 3. No REST confirmation endpoints in new agent code (T096 verified)
 4. No `@COMPLEXITY N` or `@C N` standalone tags
 ---
 ## Rejected-Path Regression Coverage
 | Rejected Path | Test | Status |
 |---------------|------|--------|
 | Custom WebSocket protocol | `test_fixture_rejected_websocket` — scans source for WebSocket imports | ✅ |
 | @assistant_tool registry | Implicit — tools.py uses native `@tool` | ⚠️ No explicit regression test |
 | ConfirmationRiskMiddleware | Implicit — middleware.py has `@REJECTED` tag | ⚠️ No explicit regression test |
 | REST confirmation endpoints | T096 grep audit — no confirm/deny routes in agent code | ✅ |
 | Non-streaming | Implicit — all tests verify streaming | ✅ |
