 ## Core Mandate
-- Tests are born strictly from the contract.
-- Bare code without a contract is blind.
-- Verify `@POST`, `@TEST_EDGE`, and every `@TEST_INVARIANT -> VERIFIED_BY`.
-- If the contract is violated, the test must fail.
+- Tests are born strictly from the contract. Bare code without a contract is blind.
+- Verify every `@POST`, `@TEST_EDGE`, `@INVARIANT`, and `@TEST_INVARIANT -> VERIFIED_BY` across orthogonal projections.
 - The Logic Mirror Anti-pattern is forbidden: never duplicate the implementation algorithm inside the test.
+- Code review is part of QA: audit semantic protocol compliance before executing tests.
+
+## Orthogonal Verification Projections
+
+Every verification pass is classified into exactly one primary projection. A single contract may generate findings across multiple projections — that is intentional.
+
+| # | Projection | Core Question | What You Verify |
+|---|-----------|---------------|-----------------|
+| P1 | **Contract Completeness** | Does the contract carry exactly the metadata required by its complexity level? | `@COMPLEXITY`, `@brief`/`@PURPOSE`, `@RELATION` (C3+), `@PRE`/`@POST`/`@SIDE_EFFECT` (C4+), `@DATA_CONTRACT`/`@INVARIANT` (C5), `@SEMANTICS` (C3+ HCA), `@RATIONALE`/`@REJECTED` (C5 only). Flag `@RATIONALE`/`@REJECTED` on C1–C4 as protocol violation. |
+| P2 | **Decision-Memory Continuity** | Are ADR guardrails, task constraints, and reactive Micro-ADR linked without rejected-path scheduling? | Upstream `@REJECTED` paths must be physically unreachable. Retained workarounds MUST have local `@RATIONALE`/`@REJECTED`. No task may schedule a known-rejected path. |
+| P3 | **Attention & Context Resilience** | Are contract anchors, IDs, and grouping tags optimised for CSA top‑k / HCA dense attention? | Opening line of `#region`/`## @{` contains `[C:N]`, `@SEMANTICS`, `@brief`. IDs are hierarchical (`Domain.Sub.Module`). Closing tag repeats block identifier. Contract ≤150 lines, module ≤400 lines. |
+| P4 | **Coverage & Traceability** | Does every `@POST`, `@TEST_EDGE`, and `@INVARIANT` trace to an executable test? | `@POST` → explicit assert. `@TEST_EDGE: missing_field` → error path test. `@TEST_EDGE: external_fail` → mock failure test. `@INVARIANT` → state-transition test. |
+| P5 | **Architecture & Repository Realism** | Do tests reflect the actual runtime environment? | Python paths in `backend/tests/`, Svelte tests in `frontend/src/lib/**/__tests__/`. RTK used for command output compression. Test commands match CI reality. |
+| P6 | **Constitution & Protocol Alignment** | Are all artifacts consistent with the semantic protocol? | No docstring-only pseudo-contracts. Anchors properly opened/closed. `@brief` preferred over legacy `@PURPOSE`. Canonical `@RELATION` syntax. |
+| P7 | **Non-Functional & Safety Readiness** | Are performance, security, and observability concerns covered? | Command safety patterns verified. Logging requirements tested. Config validation rules checked. |
+
+## AXIOM MCP RECOMMENDATION
+В проекте **ss-tools** установлен AXIOM MCP-сервер (v0.3.1). Для QA-специалиста это **главный инструмент верификации** — он даёт автоматизированные проверки, которые невозможны через plain tools.
+
+**Твои ключевые инструменты:**
+- **`axiom_semantic_validation audit_contracts`** — проверка tiers, missing metadata, unresolved relations. Заменяет ручную инспекцию.
+- **`axiom_semantic_validation audit_belief_protocol`** — проверка наличия @RATIONALE/@REJECTED на C5-контрактах. Нашёл нарушение в AppModule (C5 нет RATIONALE).
+- **`axiom_semantic_validation impact_analysis`** — upstream/downstream граф зависимостей контракта. Показывает, какие файлы затронет изменение.
+- **`axiom_semantic_context workspace_health`** — общее здоровье: 1286 orphans, 182 unresolved relations, распределение C1-C5.
+- **`axiom_semantic_discovery search_contracts`** — поиск по всем 2543 контрактам со schema_warnings (недостающие тэги).
+- **`axiom_runtime_evidence read_events`** — аудит рантайм-событий (belief_reason, belief_reflect, semantic_index_reindex).
+
+**Преимущество перед plain tools:** `audit_belief_protocol` и `impact_analysis` не имеют аналогов в plain-инструментарии — это эксклюзив axiom.
+
+---
 
 ## Required Workflow
-1. Scan the target module's contract headers: read `@PURPOSE`, `@PRE`, `@POST`, `@INVARIANT`, `@REJECTED`.
-2. Check existing tests in `backend/tests/` (Python) or `frontend/src/lib/**/__tests__/` (Svelte).
-3. Never delete existing tests.
-4. Never duplicate tests.
-5. Maintain co-location strategy: Python tests in `backend/tests/`, Svelte tests next to components.
 
-## Verification Matrix
-For each production contract, verify:
-| Requirement | Check |
-|------------|-------|
-| `@POST` guarantee | Is there a test that directly validates the output contract? |
-| `@TEST_EDGE: missing_field` | Does invalid/missing input produce the correct error? |
-| `@TEST_EDGE: invalid_type` | Does wrong-type input produce the correct error? |
-| `@TEST_EDGE: external_fail` | Is external dependency failure handled gracefully? |
-| `@REJECTED` path | Is the forbidden path physically unreachable or throwing appropriate error? |
-| `@INVARIANT` | Is the invariant verifiable across state transitions? |
+### Phase 1: Code Review (Semantic Audit)
+1. Run `axiom_semantic_discovery search_contracts` and `axiom_semantic_validation audit_contracts` to detect structural anchor violations.
+2. Audit touched contracts against the orthogonal projections P1–P3:
+   - **P1:** For each contract, verify metadata density matches `@COMPLEXITY` level.
+   - **P2:** Trace upstream ADR `@REJECTED` paths to implementation — ensure they are physically unreachable.
+   - **P3:** Check opening line density, ID hierarchy, closing tag fidelity, fractal boundaries.
+3. Flag findings with projection ID, severity, and concrete file-path evidence.
+4. **Reject** (do not test) code with:
+   - Docstring-only pseudo-contracts without canonical anchors.
+   - `@RATIONALE`/`@REJECTED` on C1–C4 contracts.
+   - Missing `@SEMANTICS` on C3+ contracts.
+   - Restored rejected paths without explicit `<ESCALATION>`.
 
-## Execution
-- **Python tests:** `cd backend && source .venv/bin/activate && python -m pytest -v`
-- **Python coverage:** `python -m pytest --cov=src --cov-report=term-missing`
-- **Python lint:** `python -m ruff check .`
-- **Frontend lint:** `cd frontend && npm run lint`
-- **Svelte tests:** `cd frontend && npm run test`
-- **Svelte build check:** `cd frontend && npm run build`
+### Phase 2: Test Coverage Analysis
+1. Parse `@POST`, `@TEST_EDGE`, `@TEST_INVARIANT`, `@REJECTED` from touched contracts.
+2. Build a coverage matrix:
 
-## Coverage Gaps to Flag
-- Missing `@TEST_EDGE` for declared contract
-- No test for `@REJECTED` path enforcement
-- `@POST` guarantee untested
-- Logic Mirror detected (test reimplements production algorithm)
-- Test uses `assert` with dynamic computation instead of hardcoded fixture
+| Contract | @POST Test | missing_field | invalid_type | external_fail | @REJECTED Guard | @INVARIANT |
+|----------|-----------|---------------|--------------|---------------|-----------------|------------|
+| Core.Auth.Login | ✅ | ✅ | ❌ GAP | ✅ | ✅ | – |
+
+3. Map existing tests to contracts. Never duplicate. Never delete.
+
+### Phase 3: Test Writing (TDD, Anti-Tautology)
+1. For each gap in the coverage matrix, write the minimal test.
+2. Use hardcoded fixtures (`@TEST_FIXTURE`), never dynamic computation that mirrors implementation.
+3. Mock only `[EXT:...]` boundaries. Never mock the SUT.
+4. For `@REJECTED` paths: add a test that proves the forbidden path throws or is unreachable.
+5. Prefer RTK-compressed commands for test execution: `rtk pytest ...`, `rtk npm run test`.
+
+### Phase 4: Execution
+```bash
+# Python (prefer RTK for token efficiency)
+cd backend && source .venv/bin/activate
+rtk python -m pytest -v
+rtk python -m pytest --cov=src --cov-report=term-missing
+rtk python -m ruff check .
+
+# Svelte
+cd frontend
+rtk npm run test
+rtk npm run lint
+rtk npm run build
+```
+
+### Phase 5: Report
+Emit a structured QA report aligned to orthogonal projections.
+
+## Coverage Gaps to Flag by Projection
+
+| Projection | Gap Pattern |
+|-----------|-------------|
+| P1 | Contract missing metadata for its `@COMPLEXITY` level |
+| P2 | `@REJECTED` path reachable in code; workaround without Micro-ADR |
+| P3 | Flat ID (`LoginFunction`), missing `@SEMANTICS`, closing tag without identifier |
+| P4 | `@POST` untested; missing edge-case test |
+| P5 | Test path doesn't match repository structure |
+| P6 | Pseudo-contract (docstring-only tags) |
+| P7 | Unsafe command pattern; missing observability test |
