 ## Work queue (ranked)
 
-1. **Add agent-level x402 spend budget guardrail** ([#4743](https://github.com/micro/go-micro/issues/4743)) — #4741 closed the streaming chat/A2A conformance item, and there are no open codex PRs in flight. The next highest-value user-facing gap is making paid tool calls safe for unattended agents: an explicit per-run spend cap beside `MaxSteps` and `ApproveTool`, deterministic in-process coverage, and inspectable refusals when the budget would be exceeded.
+1. **Checkpoint and resume durable agent runs** ([#3902](https://github.com/micro/go-micro/issues/3902)) — #3906 closed the cross-provider conformance item (#3901), and there are no open `codex` PRs in flight. The highest-value remaining Next-phase gap is now durability: flows already checkpoint and resume, but long agent runs still do not. Closing this asymmetry makes services → agents → workflows feel like one runtime under interruption and deploy/restart conditions. Keep it additive; do not break the public agent API.
+2. **Broaden provider streaming and keep chat/A2A streaming end to end** ([#3903](https://github.com/micro/go-micro/issues/3903)) — after durability, streaming is the next developer-visible seam in the inner loop. Real chat and long-running A2A tasks need token streaming to stay coherent from provider → `ai.Stream` → `micro chat` → A2A `message/stream`, with mock/default CI coverage plus key-gated live provider checks and safe fallback for non-streaming providers.
+3. **Trace agent runs as OpenTelemetry spans** ([#3908](https://github.com/micro/go-micro/issues/3908)) — the blog/README/roadmap story promises an operable harness, and the developer on-ramp now includes chat, inspect, and run-history checkpoints. The next observability gap is production-grade trace correlation for `RunInfo`: steps, tool calls, delegation, status, durations, and failures should be visible as spans while defaulting to no-op when tracing is not configured.

-AVOID DIMINISHING-RETURNS CHURN — this is the most important judgment you make. Before ranking anything, ask: *would a real user notice this, or is it the loop grooming itself?* Do NOT queue: another regression-guard/breadcrumb/"verify the docs stay linked" test around docs the loop already wrote; the Nth robustness workaround for a weak provider's malformed output (e.g. AtlasCloud text-tool-call repair) once the agent already tolerates that class; another variation of a subsystem that has been hardened several times recently (e.g. plan/delegate notify/side-effect edge cases). If an area has had several increments with no user-visible gain, it is DONE for now — mark further work there `needs-human` and rank something with real headroom instead (new capability in gateway/flow/model/store, interop depth, observability). A full queue is not the goal; a queue of things that matter is.
+(3) MAINTAIN THE QUEUE in `.github/loop/PRIORITIES.md` — a SINGLE ordered list, highest-value first, each item linking a scoped, CI-verifiable issue (#N); roadmap phase is the primary ordering, internal findings (cohesion gaps, DX friction, missing pieces) interleaved by value. For any prioritized gap with no issue, file one: `gh issue create --label codex --label enhancement --title "<scoped task>" --body "<goal, scope, acceptance criteria>"`.

-OUTPUT — default to NOT committing.

-Open a PR for `.github/loop/PRIORITIES.md` ONLY when the change is MATERIAL — meaning it changes what the builder builds next: (a) the top open item changes, (b) an item is added or removed, or (c) a top item's issue closed and must be dropped. Do NOT open a PR to reorder items below the top, reword descriptions, refresh notes, or "keep it current" — a re-rank that doesn't change the next build is not worth a commit, and this churn is the loop's single biggest waste.

-# Examples wayfinding
-
-Use this index when you want the shortest path from a first runnable agent to the
-next services, agents, workflows, and interop examples. Every command below is
-provider-free unless the example README says otherwise.
-
-## Pick by goal
-
-| Goal | Start here | Run or verify | Then try |
-|------|------------|---------------|----------|
-| Run the smallest no-secret agent | [`first-agent`](./first-agent/) | `go run ./examples/first-agent` | [`agent-demo`](./agent-demo/) for a larger service-backed agent |
-| Prove the maintained 0→hero path | [`support`](./support/) | `go run ./examples/support` and `go test ./examples/support` | [`zero-to-hero` guide](../internal/website/docs/guides/zero-to-hero.md) |
-| See planning and delegation | [`agent-plan-delegate`](./agent-plan-delegate/) | `go run ./examples/agent-plan-delegate` | [`plan-delegate` guide](../internal/website/docs/guides/plan-delegate.md) |
-| Expose services through MCP | [`mcp/hello`](./mcp/hello/) | follow [`mcp`](./mcp/) setup | [`mcp/crud`](./mcp/crud/) and [`mcp/workflow`](./mcp/workflow/) |
-| Try A2A or gRPC interop next | [`agent-demo`](./agent-demo/) plus gateway docs | run the example, then use the gateway docs | [`grpc-interop`](./grpc-interop/) |
-| Add workflow durability | [`flow-durable`](./flow-durable/) | `go run ./examples/flow-durable` | [`flow-loop`](./flow-loop/) |
-
-## Recommended adoption path
-
-1. **First service:** run [`hello-world`](./hello-world/) to learn service
-   registration, handlers, client calls, and health checks.
-2. **First agent:** run [`first-agent`](./first-agent/) with
-   `go run ./examples/first-agent`; it uses a deterministic mock model and needs
-   no provider key.
-3. **0→hero reference:** run [`support`](./support/) with
-   `go run ./examples/support`; it keeps typed services, an agent chat loop, an
-   event-driven flow, and an approval gate in one maintained example.
-4. **Interop next:** use [`mcp/hello`](./mcp/hello/), [`mcp/crud`](./mcp/crud/),
-   and [`mcp/workflow`](./mcp/workflow/) when you are ready to expose tools to
-   external AI clients.
-5. **Workflow depth:** use [`flow-durable`](./flow-durable/) once the agent path
-   needs checkpointed, resumable deterministic work.
-
-## CLI wayfinding
-
-The installed CLI prints the same path:
-
-```bash
-micro examples
-micro agent demo
-micro zero-to-hero
-```
-
-Keep this file, [`README.md`](../README.md), and the `micro examples` output in
-sync so new developers can find `examples/first-agent` and `examples/support`
-from one documented path.

-# First Agent
-
-This is the smallest runnable service-backed agent in the repository. It sits
-between `micro new helloworld` and the full [`examples/support`](../support/)
-0→hero reference.
-
-It runs with a deterministic mock model, so you do not need `ANTHROPIC_API_KEY`,
-`OPENAI_API_KEY`, or any other provider secret.
-
-```bash
-go run ./examples/first-agent
-```
-
-Expected transcript:
-
-```text
-First agent (provider: mock, no API key)
-> Summarize my next steps
-  [notes] listed starter notes
-assistant: Your first agent read the notes service and found three steps: install the CLI, run a service, then chat with an agent.
-✓ service-backed agent completed without provider secrets
-```
-
-## What it demonstrates
-
-- `notes` is a normal Go Micro service with one RPC method.
-- `assistant` is an agent scoped to that service via `agent.Services("notes")`.
-- The mock model requests the service tool through the normal agent tool handler.
-- The final answer proves the service → agent path without a live model key.
-
-CI keeps this path runnable with:
-
-```bash
-go test ./examples/first-agent
-```
-
-## Next chat, inspect, and debug breadcrumbs
-
-This example exits after one in-process `assistant.Ask` call so it stays tiny and
-provider-free. When you move from this transcript to a long-running agent, keep
-these commands nearby:
-
-```bash
-micro run
-micro chat assistant --prompt "Summarize my next steps"
-micro inspect agent assistant
-micro agent doctor assistant
-```
-
-Use the [no-secret first-agent guide](../../internal/website/docs/guides/no-secret-first-agent.md)
-to compare this transcript with the CLI demo, then keep the
-[debugging guide](../../internal/website/docs/guides/debugging-agents.md) open for
-preflight, doctor, inspect, and history checks. After that, continue to
-[`examples/support`](../support/) for the full services → agents → workflows
-lifecycle with a flow trigger and an approval gate.
