+The ranked work queue for the autonomous improvement loop. The
+**architecture-review** pass (the *architect*) owns this file: each run it turns
+the [roadmap](../../ROADMAP.md) plus an internal scan (gaps in the
+services → agents → workflows lifecycle, API coherence, drift, tech debt, test and
+DX friction) into a single ordered list — highest-value first — and links each
+item to a tracking issue. The hourly **continuous-improvement** pass works the
+**top item whose issue is still open**. So the architect decides *what*, and the
+increment loop *builds* it.
 
-**Bias to capability, not busy-work.** The top of this queue is net-new capability
-from the roadmap's *Now/Next* items. Hardening/conformance/DX polish is background
-work (roadmap *Ongoing*) — kept low here and capped, never allowed to crowd out
-capability. If an area has had several increments with no user-visible gain, it is done
-for now; rank real-headroom capability instead.
+**Reading / editing.** An item is done when its linked issue closes (the increment
+that builds it adds `Closes #<issue>`). Roadmap phase (Now → Next → Later) is the
+primary ordering; internal findings are interleaved by value, not kept in a
+separate list. The human can reorder this list — or the issues — at any time to
+redirect the loop; direction always wins.

 ## Work queue (ranked)
 
-### Capability — the headline (roadmap: Now / Next)
+1. **Emit OpenTelemetry spans from agent run history** ([#4218](https://github.com/micro/go-micro/issues/4218)) — streaming coverage shipped via #4226, so close the next agentic-depth operability seam called out by the roadmap and blog: `RunInfo`/history and production traces should tell the same story for model steps, tool calls, retries, delegation, and failures, making `micro inspect` and deployed traces feel like one debugging path.
+2. **Add examples wayfinding index for first-agent adoption** ([#4223](https://github.com/micro/go-micro/issues/4223)) — keep developer adoption weighted with internal hardening: the README and getting-started guide now have a stronger first-agent path, but examples remain spread across docs, CLI output, and directories. A single CI-guarded examples map should make the smallest no-secret agent, the 0→hero support app, and next interop examples discoverable from one place.
 
-1. **A2A external-client conformance** ([#4815](https://github.com/micro/go-micro/issues/4815)) — make the gateway easier for non-go-micro agents to discover and stream from by serving the well-known agent card path and spec SSE events.
-2. **AP2 mandate foundation for agent payments** ([#4841](https://github.com/micro/go-micro/issues/4841)) — add opt-in checkout/payment mandate signing and verification so A2A-carried payment authority can settle over x402 without changing defaults.
-3. **Kubernetes CRD reconciler foundation** ([#4842](https://github.com/micro/go-micro/issues/4842)) — turn the shipped alpha `Agent`, `Service`, and `Flow` CRDs into a minimally runnable native deployment path with workload reconciliation and status conditions.
-
-### In flight — do not re-queue
-
-_None right now._
-
-### Background — hardening & DX (roadmap: Ongoing; capped)
-
-_Background hardening is intentionally empty right now. Recent work covered first-agent
-wayfinding, plan/delegate recovery, provider fallback repair, streaming, memory
-compaction, retry controls, provider-failure inspection, x402 buyer safety, gRPC-reflection MCP,
-MCP result conformance, and the alpha Kubernetes CRD surface. Further churn in those
-areas should be marked `needs-human` unless it unlocks a clear user-visible capability._

-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: post a concise assessment as a comment on this issue (#__ISSUE__) — what shipped, what's in flight, the top risks/gaps, and the reasoning behind the ranking. If the ranking actually changed, open ONE PR for `.github/loop/PRIORITIES.md`: `git switch -c codex/planner-__ISSUE__`, `git push -u origin codex/planner-__ISSUE__`, `gh pr create --base master --label codex --title "<title>" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`.

-OUTPUT — default to NOT committing. Post a concise assessment as a comment on this issue (#__ISSUE__): what shipped, what's in flight, the top real gaps, and — honestly — whether the recent increments have been high-value or busy-work. Then, in almost all cases, just close this issue (`gh issue close __ISSUE__`) with NO PR.
-
-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.

-- **Flow human-in-the-loop pause/resume** — a flow step can suspend a run for external input with `flow.Await(key, prompt)` (or `flow.AwaitStep`): the run checkpoints with status `waiting` and `Execute` returns cleanly. `Flow.Waiting` lists suspended runs with what they await, and `Flow.ResumeWith(ctx, runID, input)` injects the input and continues from the next step. Recovery (`ResumePending`) skips waiting runs since they need input, not a restart. (`flow/`)
-- **Kubernetes reconcile core (alpha)** — `kubernetes.Reconcile(desired, observed)` decides the single action needed to converge an `Agent`/`Service`/`Flow` resource toward its Deployment (create / update / noop) and returns `Ready`/`Error` status conditions. Dependency-free (no controller-runtime / client-go) and fully unit-testable; a future operator binary supplies observed state and applies the action. (`deploy/kubernetes/`)
-- **In-process "local network" fast-path (opt-in)** — `client.Local()` lets a unary `Call` to a service running in the same process skip the network transport and dispatch straight to that server's handlers (for raw `codec/bytes.Frame` bodies — the shape agent/MCP/flow tool calls use), running the same router, wrappers, and codecs. In a benchmark this cut an in-process call from ~545µs to ~28µs (≈20×) with ~3.6× fewer allocations. Off by default; falls back to the network path for anything it doesn't cover. (`client/`, `server/`, `internal/network/`)
-- **`micro.Local()` service option** — turn on the in-process fast-path for a whole service in one place: every co-located unary call its client makes (agent tool calls, flow dispatch, gateway → service) takes the fast-path, with no per-call wiring. Off by default; a no-op for distributed deployments. (`service/`, root `options.go`)
-
-### Changed
-- **Remote agent chat streaming** — `micro chat` now streams replies from remote agents instead of waiting for the full response. (`cmd/micro/`, `agent/`)
-- **A2A external-client conformance** — the A2A gateway now serves the Agent Card at the spec 0.3.0 `/.well-known/agent-card.json` (keeping `/.well-known/agent.json` as a legacy alias), and `message/stream` emits spec-shaped `status-update`/`artifact-update` events ending in a `final:true` status-update instead of repeated full `Task` snapshots — and never sends `result` and `error` together. Standard A2A clients (ADK, LangGraph, a2a-SDK) can now discover and stream from go-micro agents. (`gateway/a2a/`)
-
-### Fixed
-- **Provider failure inspection metadata** — provider failures recorded during agent runs now retain classification metadata for inspection. (`agent/`, `ai/`)
-
-### Security
-- **x402 spend-cap hardening** — the paying `Client` now refuses a 402 whose `maxAmountRequired` is not a positive integer (a swallowed parse error or negative amount previously bypassed the budget cap), and a new `Config.RequireSettlement` fails closed when a paid request is served by a verify-only facilitator that never captures funds. (`wrapper/x402/`)
-- **A2A push-notification SSRF guard** — the A2A gateway no longer delivers task push notifications to caller-supplied URLs that resolve to loopback, private, link-local (incl. cloud metadata), or unspecified addresses. Callbacks are validated when set and re-checked at dial time on the resolved IP (DNS-rebinding safe); non-http(s) schemes are rejected. `Options.AllowPushURL` (and `a2a.WithPushURLPolicy` for embedded handlers) lets operators authorize trusted in-cluster receivers. (`gateway/a2a/`)

 Go Micro is an **agent harness** and service framework for Go.

+
 A harness is the runtime around an agent: the tools it can call, the memory it keeps, the guardrails that bound it, the workflows that trigger it, the services it depends on, and the protocols other agents use to reach it. 
 
 Go Micro gives you the harness as Go code. Build an agent and it gets a model, memory, tools, planning, delegation, guardrails, and service discovery; it is reachable over [MCP](https://modelcontextprotocol.io/) and [A2A](https://a2a-protocol.org). Write services and every endpoint becomes an AI-callable tool. Orchestrate the deterministic parts with durable flows. Agents, services, and flows share one runtime because an agent is a distributed system, and building one is building a service.

+- **Failure & resilience** — timeouts, rate limits, cancellation, deadline/context
+  propagation, retry/backoff.
+- **Getting-started contract** — define and CI-verify the 0→1 and 0→hero flows.
 
-- **Agents that pay (x402 buyer in the runtime).** The seller side ships (paid
-  tools via the `wrapper/x402` middleware) and the buyer `x402.Client` (a
-  budget-capped `Payer` that turns a `402` into pay-and-retry) exists — but an
-  agent can't yet *autonomously* pay for a paid tool. Wire the buyer into the
-  agent tool loop: a budget-capped `AgentPayer` so an agent that hits a
-  payment-required tool settles it within budget and retries, with the spend
-  gated (like `ApproveTool`) and observable in `RunInfo`/traces. This makes
-  go-micro a runtime for **autonomous agent commerce**. *(flagship — decomposed
-  into issues in the loop queue)*
-- **AP2 mandate foundation** ([#3552](https://github.com/micro/go-micro/issues/3552))
-  — verifiable payment **mandates** (a Checkout Mandate and a Payment Mandate),
-  signed and attached over A2A, with the Payment Mandate naming an x402 rail. The
-  authorization/audit layer above A2A + x402 that positions go-micro early in the
-  emerging agent-payments standard (Google's AP2, standardized via FIDO).
-  Additive and opt-in.
+## Next — agentic depth
 
-## Next — reach & deployment
+- **Durable agent loop** — resume a long run via `Checkpoint` (flows already do).
+- **Streaming** — broaden provider-backed `ai.Stream` coverage and keep chat/A2A streaming end to end.
+- **Agent observability** — `RunInfo` → OpenTelemetry spans.
 
-- **gRPC-reflection MCP** — derive MCP tools from *any* gRPC service via server
-  reflection, not just go-micro-native handlers. Point the gateway at an external
-  gRPC service and its methods become agent tools — a large jump in what an agent
-  can operate.
-- **Kubernetes operator + CRDs** — `Agent`, `Service`, and `Flow` as first-class
-  Kubernetes resources; an operator reconciles them into Deployments wired to the
-  registry. The production deployment story for teams already on K8s.
+## Later
 
-## Later — exploratory
+- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
+  richer A2A live-stream reconnection (`tasks/resubscribe`) and `input-required`
+  handoffs.
 
-- **Runtime-fitness loop** — a persistently-running dogfood app (Mu) plus an
-  operator/canary loop role, so the autonomous loop evolves go-micro against
-  **real runtime signal** (latency, errors, cost) with canary + rollback — not
-  just green CI. The demand signal the loop is missing today.
-- **HTTP/3 transport**; richer A2A live-stream reconnection (`tasks/resubscribe`,
-  `input-required` handoffs); memory management (summarization, retrieval/RAG).
+## Developer experience (ongoing)
 
-## Ongoing — hardening & DX (background, not the headline)
-
-Continuous but **capped** so it never crowds out capability: cross-provider
-conformance, failure/resilience (timeouts, cancellation, retry/backoff), the
-0→1 and 0→hero getting-started contract, streaming/observability coherence, and a
-seamless CLI inner loop (scaffold → run → chat → inspect → deploy). Real, but
-maintenance — the loop should spend the majority of its cycles on the capability above,
-not here.
+- A seamless CLI inner loop (scaffold → run → chat → inspect → deploy); UI
+  discipline (trim what isn't great); a maintained real-world example that doubles
+  as the 0→hero reference; docs kept in lockstep with the code.

-# Kubernetes deployment foundation (alpha)
-
-This package is the first opt-in Kubernetes foundation for the Go Micro lifecycle:
-`Service`, `Agent`, and `Flow` resources. It is intentionally experimental and
-additive. Nothing in the Go Micro runtime installs these resources or changes
-production defaults.
-
-## What is included
-
-- Alpha CRD manifests in `config/crd/` for `agents.micro.dev`,
-  `services.micro.dev`, and `flows.micro.dev`.
-- A small dependency-free mapper that turns a desired Go Micro resource into the
-  Kubernetes `Deployment` shape an operator reconciliation loop will own.
-- A dependency-free `Reconcile(desired, observed)` core that decides the one
-  action needed to converge (create / update / noop) and the `Ready`/`Error`
-  status conditions — no controller-runtime, no client-go, fully unit-testable.
-  A future operator binary supplies the observed state and applies the action;
-  only that adapter needs the Kubernetes client.
-- Unit tests that validate the structural CRD fragments, the Agent-to-Deployment
-  mapping, and the reconcile decision/conditions.
-
-## Local validation
-
-```sh
-go test ./deploy/kubernetes
-```
-
-If you have a Kubernetes cluster and `kubectl` available, you can also perform a
-server-side dry run of the CRDs:
-
-```sh
-kubectl apply --dry-run=server -f deploy/kubernetes/config/crd/
-```
-
-The manifests are `v1alpha1`; expect the API shape to evolve before this becomes
-a production operator.

-## 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. **Paid tools:** run [`agent-x402-buyer`](./agent-x402-buyer/) to see an
-   agent pay a local x402-protected tool with a mock facilitator and budget.
-6. **Workflow depth:** use [`flow-durable`](./flow-durable/) once the agent path
-   needs checkpointed, resumable deterministic work.

-# Agent x402 buyer
-
-This example shows an agent paying for a paid HTTP tool with x402 without using
-live funds or a live chain.
-
-It starts a local paid endpoint guarded by `wrapper/x402` seller middleware and a
-mock facilitator. A deterministic mock-model agent calls that endpoint as a tool,
-receives the HTTP 402 challenge, pays with `AgentPayer`, stays inside
-`AgentBudget`, retries the request, and prints the spend recorded for the run.
-
-```bash
-go run ./examples/agent-x402-buyer
-```
-
-Expected output includes:
-
-- the paid tool response,
-- one facilitator verify and settle call, and
-- `run spend: 7 smallest units (budget 10)`.
-
-The payment token and facilitator are intentionally local development fakes. To
-settle real x402 payments, keep the same `AgentPayer` / `AgentBudget` shape but
-replace the payer with a wallet-backed implementation and configure the seller
-middleware with a hosted or self-run x402 facilitator.
