There was a problem hiding this comment.
Proto and RFC look good: the wire change is additive, the zero value is a sentinel, and the RFC matches the proto fields. I have one suggestion about a test.

Summary: Queue enablement needs a dedicated lookup: validation results and the current queue row do not identify the state covering an arbitrary commit. Define GetQueueStatus with an optional change URI and one selected state, commit generated bindings, and document inclusive boundaries, intermediate commits and error semantics in the indexed RFC. The RPC remains unimplemented until the final layer. Part 1 of 4: API and RFC → storage → transitions and materialization → lookup. Test Plan: Build the published bindings and run the Stovepipe server tests. The final stack also passes all 27 Stovepipe unit, MySQL integration, service integration and end-to-end targets.

## Why? Queue enablement needs durable internal state and separate read models so orchestration updates do not alter enablement history. ## What? Extend the existing queue snapshot, add immutable QueueLog and derived QueueSummary records, and implement key-oriented stores with conditional writes. Add queue and read-model schemas, with backend tests for byte-exact queue identity and independent projection versions. ## Test Plan Run the Stovepipe storage unit and MySQL integration tests. ## Revert Plan Revert this layer together with any dependent layers in the stack. ## Issue Links None — this is a standalone queue-status proposal. ## Stack Review in this order; each PR targets the preceding branch. 1. [API and RFC](uber#854) 2. [Storage](uber#855) (this PR) 3. [Transitions and materialization](uber#856) 4. [Lookup](uber#857)

…r#856) ## Why? Queue enablement changes must preserve coordination fields and remain recoverable when history or summary writes fail. ## What? Add an internal TransitionController with Initialize, Prepare and Apply, plus queuelog.Materializer.PersistLog. Retain the previous occurrence before replacing internal enablement and materialize the committed winner afterward. Prepared retries preserve the accepted boundary; optimistic locking handles operational races. Startup registers configured queues as disabled without overwriting registered enablement. ## Test Plan Unit, service integration and end-to-end tests cover competing decisions, operational races, projection races and failed writes. Run make local-stovepipe-start for local startup with schemas applied before registration. Changing enablement uses the internal transition controller; this layer adds no mutation RPC or CLI. ## Revert Plan Revert this layer together with any dependent layers in the stack. ## Issue Links None — this is a standalone queue-status proposal. ## Stack Review in this order; each PR targets the preceding branch. 1.
