Production readiness · v2.0.0
v2.0.0 is not ready until chaos and rollback evidence close
The 2026-10-28 review protects the planned 2026-11-02 cutover from checkbox readiness.
Evidence matrix
| Area | State | Evidence or gap |
|---|---|---|
| Ownership and support | Ready | Platform and Reliability agreed |
| Contract compatibility | Ready | Payload and authentication unchanged |
| Observability | Conditional | Blast-radius proof required |
| Failure isolation | Blocking | Chaos cases not executed |
| Rollback | Conditional | Production-like rehearsal required |
| Producer validation | Conditional | Fixtures due 2026-10-16 |
A blocking criterion moves 2026-11-02. Any waiver needs an owner and expiry.
