Reasonix v5 Stable Production Checklist

Reasonix v5.9.9 is frozen as a stable release candidate. This checklist is the release gate for PR #5217 and future v5-stable maintenance work.

Release Gate

All checks below must pass before the v5 stable release candidate is merged.

1. Runtime Safety

• Sandbox isolation is verified.
• Resource budgets use ledger-based two-phase reservation and commit.
• No shared execution context can leak across sandboxed executions.

2. Control System Stability

• Distributed control plane is active and deterministic.
• Global equilibrium layer is deterministic.
• No single meta-controller is reintroduced.

3. Memory System Safety

• Causal compression is stable.
• Long-tail predictive and causal signal retention is validated.
• Truth-lock decay changes influence weight only, not correctness.

4. Predictive System Isolation

• Shadow observer remains read-only.
• Prediction-action bridge is advisory-only.
• Predictive warnings do not feed back into execution automatically.

5. Temporal System

• Dual logical and physical time reporting is visible.
• Lag and damping windows remain separated.
• Physical latency variance is not hidden by logical time normalization.

6. Architecture Freeze

• system.StableSystemContract() validates the v5.9.9 release boundary.
• system.ArchitectureLocked is enabled.
• v6-pre diagnostics remain observation-only.

7. Observability

• Trace and diagnostic systems remain non-invasive.
• Layer-collapse diagnostics do not affect runtime, prompts, provider requests, or tool schemas.

Final Release Flow

1. Validate the stable system contract.
2. Confirm the architecture lock is enabled.
3. Confirm v6-pre diagnostics are isolated.
4. Pass the production checklist.
5. Pass system.ReleaseGuard().
6. Merge as the v5.9.9 stable release candidate.
