+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

-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

+redirect the loop; direction always wins.

 ## Work queue (ranked)
 
-### Capability — the headline (roadmap: Now / Next)
+1. **Make AtlasCloud plan-delegate complete the required notify side effect** ([#4255](https://github.com/micro/go-micro/issues/4255)) — Now-phase getting-started contract and cross-provider conformance overlap here: the live AtlasCloud 0→hero plan/delegate harness can now parse the initial plan call, but still exits before the required task and notify side effects, so a provider-backed services → agents → workflows path is not yet reliable.
+2. **Link examples wayfinding from website getting-started path** ([#4241](https://github.com/micro/go-micro/issues/4241)) — keep adoption weighted with hardening after the examples index shipped: the repo README and CLI now point at the first-agent/0→hero map, but go-micro.dev getting-started and quickstart pages still skip the examples index/support reference links that make the no-secret on-ramp discoverable.
+3. **Make AtlasCloud guarded delegation pass reliably** ([#4244](https://github.com/micro/go-micro/issues/4244)) — Now-phase cross-provider conformance remains important after the Minimax request-shape fallback, duplicate delegated-notification replay fixes, and OpenAI-compatible text tool-call parsing shipped; keep it in queue until the live agent harness consistently observes the guarded delegate within the retry budget.
 
-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.

-- **Compacted memory summaries** — agent memory now exposes compacted run summaries for easier inspection and recovery. (`agent/`)
-- **CLI input resume for agent runs** — the CLI can resume agent runs that require additional user input. (`cmd/micro/`, `agent/`)

-
-### Security

 5. Battle-tested: works across every provider, fails safely, observable.
 
-The forward work is **net-new capability**, not more hardening. Maintenance
-(conformance, resilience, DX polish) continues in the background (see *Ongoing*
-below) — but it is not the roadmap. This capability work is.
+## Now — hardening
 
-## Now — capability
+- **Cross-provider conformance** — the same agent scenario across all seven
+  providers, gated on keys, on a schedule.
+- **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.
-- Unit tests that validate the structural CRD fragments and dry-run the
-  Agent-to-Deployment mapping.
-
-## 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.

-# 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.
