-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.

+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.
 
-**Off-limits to the loop** (the architect proposes these as notes, never as queue

 ## Work queue (ranked)
 
-1. **Add CI-verified first-agent chat/inspect fixture** ([#4644](https://github.com/micro/go-micro/issues/4644)) — With plan/delegate persistence hardened and the first-agent breadcrumbs refreshed, the highest-value remaining adoption gap is proving the real CLI-shaped scaffold → run → chat → inspect loop for the smallest provider-free agent. Keep this focused and separate from the richer support 0→hero reference so a new developer can trust the first-agent path without provider keys.
-2. **Add scheduled cross-provider agent conformance** ([#4649](https://github.com/micro/go-micro/issues/4649)) — The Now roadmap still calls for battle-testing the same agent scenario across providers. After the no-secret first-agent fixture, verify tool-calling, multi-step turns, plan/delegate, and guardrails on the live-provider matrix behind key-gated scheduled CI, without slowing the local harness.
-3. **Harden agent provider failure resilience** ([#4650](https://github.com/micro/go-micro/issues/4650)) — The next reliability seam is making timeouts, cancellation, rate limits, retry/backoff, and inspectable failure metadata predictable through the agent loop. Keep this scoped to existing behavior and tests; surface any breaking API or default changes as human review notes instead of queue work.
+### Capability — the headline (roadmap: Now / Next)
 
-_Seeded by Claude Code from the roadmap + open issues; thereafter maintained by the
-architecture-review pass._
+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._

+- **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).
 
-- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
-  richer A2A live-stream reconnection (`tasks/resubscribe`) and `input-required`
-  handoffs.
+## Ongoing — hardening & DX (background, not the headline)
 
-## Developer experience (ongoing)
-
-- 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.
+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.

+# 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.

+description: "Go Micro v6.6.0 strengthens the first-agent on-ramp, hardens plan/delegate recovery, and adds CI-backed security checks."
+---
+
+# What's New in Go Micro: v6.6.0
+
+*July 11, 2026 • By the Go Micro Team*
+
+Go Micro v6.6.0 is a harness reliability release. The theme is the same services → agents → workflows lifecycle, but with more of the first-agent path covered by local checks and more recovery paths made deterministic when agents resume, retry, delegate, or notify.
+
+## The first-agent path is harder to break
+
+The README, website docs, examples, and 0→hero guide chain now have more harness coverage. The CLI and docs keep the path from install troubleshooting through `micro agent demo`, quickcheck, examples, the smallest first-agent, debugging, and 0→hero in one consistent order.
+
+That matters because the first agent is where framework promises become real: scaffold a service, run it, chat with an agent, inspect what happened, and then graduate to workflows.
+
+## Plan/delegate recovery is steadier
+
+Plan/delegate got another reliability pass across side effects, notification replay, plan-only actions, timeout completion, and completed-plan recovery. These fixes are not flashy, but they are exactly the kind of harness work that keeps an agent from repeating work or losing state when a multi-step run is interrupted.
+
+## Provider fallback keeps improving
+
+AtlasCloud fallback handling now recovers more awkward provider outputs, including workspace repair calls, empty-argument text tool calls, spoken notification replays, and A2A fallback artifact text. The goal is pragmatic interop: when a provider response is close enough to a safe tool call, the harness should repair it; when it is not, the failure should stay visible.
+
+## Security checks joined the loop
+
+CI now includes a govulncheck gate and the autonomous loop can route vulnerability failures into triage. The release also includes toolchain and dependency updates for reachable CVEs, keeping the service framework side of the harness current while agent features continue to land.
+
+## Read the changelog
+
+The full release notes are in the [CHANGELOG](https://github.com/micro/go-micro/blob/master/CHANGELOG.md).

-`Payer` is an interface (`Pay(ctx, Requirements) (payment string, error)`) — the consumer counterpart to `Facilitator`. The budget accumulates across calls, so a long-running agent can be handed a fixed allowance for a task. Budget is reserved before payment is created, which means parallel paid calls cannot race past the cap; if payment creation or verification fails, the reservation is released. (The agent-level `AgentMaxSpend` option, wiring this into the agent loop next to `MaxSteps`/`ApproveTool`, is the next step.)

+For unattended agents, set the same cap at the agent tool-execution layer so paid tools are refused before their handler — and therefore before a payer — can run:
+
+```go
+agent := micro.NewAgent("buyer",

+```
+
+`AgentMaxSpend` is disabled by default (`0`). `AgentToolSpend` records the price discovered from your shoppable MCP/x402 catalog for the tools this agent may call. When a call would exceed the per-run allowance, the result is a normal structured guardrail refusal with `Refused: "spend_budget"` and an explanatory error in the run timeline/inspect output, distinct from provider/model failures.
