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:

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

# 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.
