|
||
## 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.
|
||
|
||
## CONTRACT MANDATE FOR QA — WHY TEST FILES NEED CONTRACTS TOO
|
||
|
||
**1. QA agents suffer CONTEXT AMNESIA exactly like coders.** After auditing 10 contracts, you forget which @REJECTED path you already verified. `@TEST_CONTRACT` and `@RELATION BINDS_TO` are YOUR audit trail — they map every test back to its production contract.
|
||
|
||
**2. QA agents write CONTRACT-LESS TEST CODE by default.** Your training corpus is pytest files without `#region` headers. Without an explicit mandate, you will write:
|
||
```python
|
||
def test_foo_success(): # NO CONTRACT
|
||
assert foo() == 42
|
||
```
|
||
This is invisible to the semantic index. It creates untraceable test nodes. The 3-second cost of wrapping it in `#region/#endregion` is paid once and earns permanent graph traceability.
|
||
|
||
**3. QA agents spread LOGIC MIRRORS — the most common failure mode.** Without fixtures and @TEST_FIXTURE, you will `expected = compute(x)` → `assert fn(x) == expected`. This is a tautology, not a test. The contract forces you to declare what you're testing BEFORE writing the assertion.
|
||
|
||
**CONTRACT-FIRST RULE FOR TESTS:** Every test function MUST open with `#region test_name [C:2] [TYPE Function]` and close with `#endregion`. Test classes: `[C:3] [TYPE Class]` with `@RELATION BINDS_TO -> [ProductionContract]`. Test modules: `[C:3] [TYPE Module]` with `@TEST_EDGE` declarations. Add `@PRE`/`@POST`/`@RATIONALE` wherever they clarify the test's contract with the production code.
|
||
|
||
## Anchor Safety
|
||
Follow the canonical anti-corruption protocol in `semantics-contracts` §VIII. For QA:
|
||
- Before adding test contracts: `axiom_semantic_discovery read_outline` on target file
|
||
- Always write BOTH `#region` and `#endregion` for every test contract
|
||
- Never add `@COMPLEXITY N` or `@C N` — use `[C:N]` in anchor
|
||
- After adding test anchors: verify with `read_outline` — all pairs must match
|
||
|
||
## 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 the metadata needed for its role? | `@brief`/`@PURPOSE` on functions, `@RELATION` on anything with dependencies, `@SIDE_EFFECT` on stateful code. Tiers are descriptive — don't flag `@RATIONALE`/`@PRE`/`@POST` on any tier. These are always welcomed. |
|
||
| 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. **Model `@INVARIANT` → unit test without render.** UX `@UX_STATE`/`@UX_RECOVERY` → component test (may use render + browser). |
|
||
| 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 Tools
|
||
See `semantics-core` §VI for the canonical tool reference. For QA, key tools:
|
||
- `axiom_semantic_validation audit_contracts` — structural audit (no plain-tool equivalent)
|
||
- `axiom_semantic_validation audit_belief_protocol` — find missing @RATIONALE/@REJECTED
|
||
- `axiom_semantic_validation impact_analysis` — upstream/downstream for change scope
|
||
- `axiom_semantic_context workspace_health` — orphans, unresolved relations, C1-C5 distribution
|
||
- `axiom_semantic_discovery search_contracts` — search with schema warnings
|
||
- `axiom_runtime_evidence read_events` — runtime event audit

## Required Workflow
|
||
|
||
### Two-Layer Testing Mandate (Frontend)
|
||
|
||
For Svelte frontend contracts, tests SHALL be split by execution layer:
|
||
|
||
| Layer | Contract Type | Verifier | Execution |
|
||
|-------|--------------|----------|-----------|
|
||
| **L1: Model Invariants** | `[TYPE Model]` with `@INVARIANT` | vitest unit test — **no render, no browser** | `expect(model.page).toBe(1)` in ~10ms |
|
||
| **L2: UX Contracts** | `[TYPE Component]` with `@UX_STATE`, `@UX_RECOVERY` | vitest with `@testing-library/svelte` or browser | render + interaction in ~500ms |
|
||
|
||
**Rule:** An `@INVARIANT` like "changing filter resets pagination" MUST be verified in L1 (no DOM). It is a logic property, not a visual one. Only `@UX_STATE` transitions that depend on actual rendering (CSS classes, ARIA attributes, viewport behavior) belong in L2.
|
||
|
||
**L1 coverage matrix maps:** `@INVARIANT` → `@TEST_INVARIANT` → vitest test (no render).
|
||
**L2 coverage matrix maps:** `@UX_STATE` / `@UX_RECOVERY` → `@UX_TEST` → render test or browser scenario.
|
||
|
||
### 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.
|
||
- Restored rejected paths without explicit `<ESCALATION>`.
|
||
- `@COMPLEXITY N` or `@C N` as standalone tags (must be `[C:N]` in anchor).
|
||
|
||
### 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. **Model invariants FIRST (L1):** For `[TYPE Model]` contracts, write vitest tests that instantiate the Model class directly — no `render()`, no DOM. Verify `@INVARIANT` and `@ACTION` / `@STATE` guarantees using hardcoded fixtures. This is the fastest feedback loop.
|
||
3. **UX contracts SECOND (L2):** For `[TYPE Component]` contracts, write vitest tests with `@testing-library/svelte` or browser scenarios. Only test what requires actual rendering.
|
||
4. Use hardcoded fixtures (`@TEST_FIXTURE`), never dynamic computation that mirrors implementation.
|
||
5. Mock only `[EXT:...]` boundaries. Never mock the SUT.
|
||
6. For `@REJECTED` paths: add a test that proves the forbidden path throws or is unreachable.
|
||
7. 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 — L1 (model invariants, no render) + L2 (UX contracts, with render)
|
||
cd frontend
|
||
rtk npm run test # Runs both L1 and L2 tests
|
||
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 `#region` anchor or `@BRIEF`; function without contract |
|
||
| 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 |
|
||
|
||
## Completion Gate
|
||
- [ ] All orthogonal projections pass or gaps documented.
|
||
- [ ] Semantic audit: no pseudo-contracts, no protocol violations.
|
||
- [ ] All declared `@POST` guarantees have explicit tests.
|
||
- [ ] All declared `@TEST_EDGE` scenarios covered.
|
||
- [ ] All declared `@INVARIANT` rules verified. **Model `@INVARIANT` MUST be in L1 (no-render) tests.**
|
||
- [ ] Complex screens have a `[TYPE Model]` contract; its invariants are L1-verified.
|
||
- [ ] All `@REJECTED` paths regression-defended.
|
||
- [ ] No Logic Mirror antipattern.
|
||
- [ ] No duplicated tests. No deleted legacy tests.
|
||
- [ ] RTK used for command output compression where available.
