Expand TestPrimaryRoutesProperty (5 -> 9 ops). New ops mirror the production shapes the failure cases hit: BatchProbeResults via UpdateNodes, SimultaneousDisconnect via UpdateNodes, SetApprovedRoutes that leaves announced RoutableIPs intact, OfflineExpiry that keeps Unhealthy set. The model now tracks announced and approved separately and recomputes the intersection. Strengthen the per-op assertions to cover invariants the model alone cannot prove: every primary must be online, every primary must currently advertise its prefix, no flap onto an unhealthy candidate when a healthy one was available, no flap off a previous primary that remains a healthy candidate. The check now takes a pre-op snapshot so the anti-flap rule has a stable reference. Add TestHAProberProperty in servertest. It drives a real TestServer with three HA-route-advertising clients through rapid-drawn sequences of ClientDisconnect / ClientReconnect / ProberTick / WaitForSnapshot ops and re-checks the same shape invariants after every step. Document the system in hscontrol/state/HA_INVARIANTS.md: a state machine over (Healthy+Online, Unhealthy+Online, Offline, OfflineExpired), fifteen numbered invariants with predicates and violation paths, and a coverage matrix mapping each invariant to its unit, servertest, and integration tests. Three rows pin the recent fixes to the invariants they enforce. |
