Add permission_gate smoke tests: per-tier capability sets + monotonicity + severity + sink + permissive + unknown-cap diagnostic

Update vault smoke tests: T2 default for inserts, T1 denied test, audit log severity verification

Wire vault_adapter to capability-based PermissionGate: VAULT_APPEND for inserts, VAULT_SCHEMA for migrations (T6 only)

Add PermissionGate — capability-tier model (T0-T6) per Sovereign Hive spec, audit log with severity flagging, permissive() for test code

Add Vault adapter smoke tests (7 assertions: bootstrap, migration idempotency, insert, dedup, fetch, hit/miss, gate rejection)

Add Vault adapter — SQLite-backed with PermissionGate interface, idempotent INSERT OR IGNORE, audit chain on writes

Add migration 003 — kv_sensitivity_profile schema with CHECK constraints + lookup index

Add strategy=joint|isolated flag + empirical findings in docstring (joint default, 10x faster, same allocation as isolated per A vs B comparison on OLMo-2-13B)

Add compare_strategies.py

Add smoke_test_v4.py

Add kv_profiler.py

Add KV interception hooks + generalised allocator + smoke tests (3/3: smoke_test_v3.py)

Add KV interception hooks + generalised allocator + smoke tests (2/3: assignment_v2.py)

Add KV interception hooks + generalised allocator + smoke tests (1/3: kv_intercept.py)

Revise candidates: swap Phi-4 (GQA, not MHA) for OLMo-2-13B (MHA), swap Mistral-3.2 (multimodal) for Mistral-Small-2409 (text). Add chat-template-aware smoke test.
