+### Layer 2.5: API docs contract
+
+```bash
+make rustdoc-check
+```
+
+Purpose:
+- Keep public docs buildable and warning-free.
+- Catch broken intra-doc links and rustdoc lint regressions early.
+
+### Layer 2.6: Python integration compatibility gate
+
+```bash
+make py-integration-gate
+```
+
+Purpose:
+- Validate package-level compatibility helpers (`version`, `version_tuple`, `has_feature`, `available_features`).
+- Reject false-green all-skipped/no-tests-ran outcomes.
+
+### Layer 2.7: Ignored subprocess integration stability
+
+```bash
+make ignored-repl-gate
+```
+
+Purpose:
+- Ensure ignored REPL/Lean subprocess integration tests complete deterministically in unattended runs.
+- Catch orphan-process cleanup regressions early.
+
+### Layer 2.8: Property-based invariant gate
+
+```bash
+make proptest-gate
+```
+
+Purpose:
+- Enforce invariant-level proptest coverage across epistemic math, signature validation, fallback behavior, and router/accounting logic.
+- Run with deterministic proptest configuration (`PROPTEST_CASES=96`, `PROPTEST_RNG_SEED=424242`, `PROPTEST_RNG_ALGORITHM=cc`) so CI/local results are reproducible.
+- Fail fast if any scoped property-test suite accidentally runs zero tests (false-green guardrail).
+
+### Layer 2.9: Claude adapter end-to-end efficacy gate
+
+```bash
+make claude-adapter-gate
+```
+
+Purpose:
+- Validate realistic Claude adapter observe/orient/decide/act scenarios, not just activation plumbing.
+- Enforce scenario-level quality assertions (context observation, signal-driven mode choice, execution/accounting outputs).
+- Guard against false green from test-filter drift by requiring at least two scenario tests to execute.
