Phase 0 (miroir-qon): Verification complete - foundation confirmed

Verified all Phase 0 definition of done criteria:
- cargo build --all: PASS
- cargo test --all: PASS (103 tests)
- cargo fmt --all --check: PASS
- cargo clippy -p miroir-core --lib: PASS
- Config round-trip YAML: PASS
- Workspace structure: Complete with 3 crates
- Dependencies: All wired per plan §4
- Tooling: rust-toolchain.toml, rustfmt.toml, clippy.toml, .editorconfig
- Project artifacts: Cargo.lock, CHANGELOG.md, LICENSE, .gitignore

Note: musl build requires cross-compilation toolchain (environment limitation),
but project is correctly configured with musl targets in rust-toolchain.toml.

+# Miroir Helm Chart Tests
+
+This directory contains test cases and validation scripts for the Miroir Helm chart.
+
+## Schema Validation Tests
+
+The `test_schema.py` script validates that the `values.schema.json` constraints are working correctly.
+
+### Test Cases
+
+| Test File | Description | Expected Result |
+|-----------|-------------|-----------------|
+| `replicas-1-sqlite.yaml` | Single replica with SQLite | PASS |
+| `replicas-2-sqlite.yaml` | Multiple replicas with SQLite | FAIL (error: backend must be redis) |
+| `replicas-2-redis.yaml` | Multiple replicas with Redis | PASS |
+
+### Running Tests
+
+```bash
+# Using Python (works without helm installed)
+python3 tests/test_schema.py
+
+# Using helm lint (requires helm)
+helm lint --strict -f tests/replicas-1-sqlite.yaml .
+helm lint --strict -f tests/replicas-2-sqlite.yaml .  # Should fail
+helm lint --strict -f tests/replicas-2-redis.yaml .
+```
+
+### Constraint Details
+
+The values.schema.json enforces that when `miroir.replicas > 1`, the `taskStore.backend` must be `"redis"`. SQLite is a single-writer database and cannot be shared across multiple pods.
+
+See values.schema.json lines 142-161 for the constraint implementation.
