+# Verification & Test Suite Specification: Store capacity bounds checking and persistence invariants
+
+## Summary
+Test coverage plan and regression harness specification addressing #24 on **EcoTask-app**.
+
+## Invariants & Test Boundaries
+1. **Happy Path**: Verifies nominal execution flow with deterministic inputs.
+2. **Boundary & Edge Cases**: Validates bounds checking, input sanitization, and state invariants.
+3. **Negative Paths**: Confirms unauthorized callers and adverse states revert cleanly without partial mutation.
+
+## Test Execution
+- Regression suites are structured to execute hermetically without external network dependencies.
+- Fixtures and mocks ensure deterministic execution across all CI runner environments.
