/// @brief Orthogonal verification, contract validation, code review, and regression defense.
/// @pre Implementation exists with declared contracts (C1–C5) and test infrastructure (pytest, vitest, ruff, eslint).
/// @post All orthogonal projections verified; contract gaps documented; rejected paths regression-defended; code review issues flagged.
/// @sideEffect Writes tests, runs linters, executes pytest/vitest, emits structured QA report.
/// @rationale Single-axis testing misses cross-projection conflicts. Orthogonal decomposition ensures that a pass in contract validation doesn't mask a decision-memory drift or an attention-format regression.
/// @rejected Testing only functional correctness without semantic audit — leaves protocol violations undetected.

## Core Mandate
- 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

### 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>`.

### Phase 2: Test Coverage Analysis
1. Parse `@POST`, `@TEST_EDGE`, `@TEST_INVARIANT`, `@REJECTED` from touched contracts.
2. Build a coverage matrix:

| 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 |
