Introduces reference models and policy_semantics integration tests to catch eviction drift, wires TTL tests through LruOccupancyModel, and extends CI/docs for the new layer. Co-authored-by: Cursor <cursoragent@cursor.com>
Clarify dual-run vs invariant-only tiers, fix strategy tables, and DRY residency probes so documentation matches how policy_semantics tests run. Co-authored-by: Cursor <cursoragent@cursor.com>
Gate exact/bounded modules and op strategies by policy-* features, remove unwired helpers, and keep a documented allow(dead_code) on the shared harness root for multi-crate partial usage (policy_semantics vs ttl). Co-authored-by: Cursor <cursoragent@cursor.com>
…TLA+ pilots. Introduce operational policy specs, independent reference oracles for all exact-tier policies, shared driver helpers, and cross-model proptests so specs drift is caught before impl dual-run. Add FIFO and LRU TLA+ modules with manual TLC runbooks. Co-authored-by: Cursor <cursoragent@cursor.com>
Split the flat specs directory so operational docs, TLA+ artifacts, and shared fragments are easier to extend; update matrix links, TLC scripts, and harness doc paths. Co-authored-by: Cursor <cursoragent@cursor.com>
