v0.5.1

0.5.1 - 2026-07-28

A patch for the scheduled-jobs surface that shipped in 0.5.0: an unset snowflake WorkerId no longer crashes every scheduler tick, and job PUT on PostgreSQL no longer returns a broken body.

Fixed

• Scheduler node heartbeat no longer throws when TenonAdmin:Id:WorkerId is unset (#24). SqlSugar evaluates expression-tree members when building SetColumns; the previous idOptions.WorkerId ?? 0 ran against a null options object and flooded the tick loop with exceptions. Locals (workerId, pid, hostName, startTime) are hoisted before the expression so the tree only sees constants and locals.
• Job update (PUT) on PostgreSQL no longer returns a non-JSON body. JobService.UpdateAsync switched to the same Updateable(entity).IgnoreColumns(...) pattern used elsewhere (Dict/User), and the nullable NextRunTime CAS is split into two branches so a ternary does not land in the expression tree.
• Multi-replica smoke is less flaky after failover. Caddy upstreams gain health checks and lb_try_duration; the multi-smoke script polls until the 5s job has three runs instead of a fixed 25s wait. Both frontend OpenAPI clients pick up the missing nodeInstanceId field that had drifted from the contract.

Changed

• Runtime architecture diagrams and README previews refreshed for in-kernel jobs, optional WorkerHost, and the SignalR hub path.
• Documented the MLPS assessment boundary (ADR-0005) and matching domain terms in CONTEXT.md.
