| 1 | # Reasonix v5 Stable Production Checklist |
| 2 | |
| 3 | Reasonix v5.9.9 is frozen as a stable release candidate. This checklist is the |
| 4 | release gate for PR #5217 and future v5-stable maintenance work. |
| 5 | |
| 6 | ## Release Gate |
| 7 | |
| 8 | All checks below must pass before the v5 stable release candidate is merged. |
| 9 | |
| 10 | ## 1. Runtime Safety |
| 11 | |
| 12 | - Sandbox isolation is verified. |
| 13 | - Resource budgets use ledger-based two-phase reservation and commit. |
| 14 | - No shared execution context can leak across sandboxed executions. |
| 15 | |
| 16 | ## 2. Control System Stability |
| 17 | |
| 18 | - Distributed control plane is active and deterministic. |
| 19 | - Global equilibrium layer is deterministic. |
| 20 | - No single meta-controller is reintroduced. |
| 21 | |
| 22 | ## 3. Memory System Safety |
| 23 | |
| 24 | - Causal compression is stable. |
| 25 | - Long-tail predictive and causal signal retention is validated. |
| 26 | - Truth-lock decay changes influence weight only, not correctness. |
| 27 | |
| 28 | ## 4. Predictive System Isolation |
| 29 | |
| 30 | - Shadow observer remains read-only. |
| 31 | - Prediction-action bridge is advisory-only. |
| 32 | - Predictive warnings do not feed back into execution automatically. |
| 33 | |
| 34 | ## 5. Temporal System |
| 35 | |
| 36 | - Dual logical and physical time reporting is visible. |
| 37 | - Lag and damping windows remain separated. |
| 38 | - Physical latency variance is not hidden by logical time normalization. |
| 39 | |
| 40 | ## 6. Architecture Freeze |
| 41 | |
| 42 | - `system.StableSystemContract()` validates the v5.9.9 release boundary. |
| 43 | - `system.ArchitectureLocked` is enabled. |
| 44 | - v6-pre diagnostics remain observation-only. |
| 45 | |
| 46 | ## 7. Observability |
| 47 | |
| 48 | - Trace and diagnostic systems remain non-invasive. |
| 49 | - Layer-collapse diagnostics do not affect runtime, prompts, provider requests, |
| 50 | or tool schemas. |
| 51 | |
| 52 | ## Final Release Flow |
| 53 | |
| 54 | 1. Validate the stable system contract. |
| 55 | 2. Confirm the architecture lock is enabled. |
| 56 | 3. Confirm v6-pre diagnostics are isolated. |
| 57 | 4. Pass the production checklist. |
| 58 | 5. Pass `system.ReleaseGuard()`. |
| 59 | 6. Merge as the v5.9.9 stable release candidate. |
