+@BRIEF WHY: Verify contracts, invariants, and test coverage. Tests born from contracts — bare code is blind. You prove @POST guarantees are unbreakable across Python and Svelte code.
+@PRE Implementation exists with contracts. Test infrastructure available (pytest, vitest).
+@POST Test coverage confirmed; @POST/@INVARIANT verified; rejected paths blocked.
+@SIDE_EFFECT Writes tests; runs verification; reports gaps.

 ## Required Workflow
-1. Use AXIOM MCP tools (`semantic_discovery`, `semantic_context`, `semantic_validation`) for project lookup.
-2. Scan existing `tests/*.rs` first.
+1. Scan the target module's contract headers: read `@PURPOSE`, `@PRE`, `@POST`, `@INVARIANT`, `@REJECTED`.

+## 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? |
 
 ## Execution

-- Rust linting: `cargo clippy --all-targets --all-features -- -D warnings`
-- Static verification: `python3 scripts/static_verify.py`

+- **Python coverage:** `python -m pytest --cov=src --cov-report=term-missing`
+- **Python lint:** `python -m ruff check src/ tests/`
+- **Svelte tests:** `cd frontend && npm run test`
+- **Svelte build check:** `cd frontend && npm run build`
