docs(priorities): refresh planner queue for 3829

.github/loop/PRIORITIES.md

@@ -21,8 +21,10 @@ changes, architectural rewrites. Those go to the human.
 
 ## Work queue (ranked)
 
-1. **Trace agent `RunInfo` into OpenTelemetry spans** ([#3867](https://github.com/micro/go-micro/issues/3867)) — #3857/#3865 closed the streaming queue item, there are no open `codex` PRs in flight, and the remaining Next-phase gap with the strongest mission fit is operability of the services → agents → workflows lifecycle. The README, website, roadmap, and recent blog all promise that agents are services you can run, chat with, inspect, and trust under the same runtime; projecting run steps, tool calls, delegation, streaming, cancellation, and errors into OTel spans makes that lived path debuggable without a public-API rewrite. Keep this additive/no-op when tracing is disabled, with tests proving representative `RunInfo` events become trace data.
-2. **Add an AP2 mandate layer over A2A and x402** ([#3552](https://github.com/micro/go-micro/issues/3552)) — this remains a forward interop investment, not a Now/Next blocker: Go Micro already has A2A agents and x402 paid tools, so a small signed-mandate foundation can keep agent payments aligned with the open-protocol story without pulling the queue ahead of adoption, resilience, streaming, or durable agent operation. Keep it additive and opt-in while the AP2/FIDO work settles.
+1. **Stabilize atlascloud plan-delegate harness timeout** ([#3826](https://github.com/micro/go-micro/issues/3826)) — #3828 closed the file-store expiry blocker, so the remaining red evaluator risk is the live-provider plan/delegate timeout where atlascloud returned an opaque RPC 408 before delegated task or notification side effects were observed. Keep this first because the loop's adoption contract depends on the same services → agents → workflows harness proving the first-agent and 0→hero paths are reliable, and failures must be classified well enough for developers and triage to act.
+2. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — once the remaining harness timeout is classified or stabilized, the highest-value Now-phase resilience gap is predictable failure semantics across agent runs, model calls, tool calls, plan/delegate, and flow handoffs. Tool retries, live-provider deadline tuning, delegated-plan completion, side-effect enforcement, and file-store isolation are in place; the lifecycle still needs cancellation/deadline propagation so work fails safely instead of becoming opaque loops.
+3. **Emit OpenTelemetry spans for agent run timelines** ([#3525](https://github.com/micro/go-micro/issues/3525)) — recent work made runs inspectable, correlated trace metadata through scheduled dispatch, verified restart resume, added opt-in tool retries, hardened provider conformance, fixed provider-emitted text tool calls, and narrowed the latest provider timeout to a diagnosability gap. The next Next-phase step is to turn that RunInfo foundation into standard OTel spans for agent runs, model calls, tool calls, checkpoint/resume, cancellation/deadlines, and failures.
+4. **Add an AP2 mandate layer over A2A and x402** ([#3552](https://github.com/micro/go-micro/issues/3552)) — this is a forward interop investment, not a Now-phase blocker: Go Micro already has A2A agents and x402 paid tools, so a small signed-mandate foundation can keep agent payments aligned with the open-protocol story without pulling the queue away from adoption, resilience, or observability. Keep it additive and opt-in while the AP2/FIDO work settles.
