client/server: in-process dispatch fast-path (opt-in)

When caller and callee run in the same process, a unary Call pays the
full network tax — pool.Get, dial, codec-over-socket, and the transport
pump — even though the handler table is right there. This adds an opt-in
fast-path that dispatches directly.

- internal/network: a neutral registry (transport.Message in/out) so
  client and server wire up without importing each other. A running server
  registers a dispatcher under its name on Start, deregisters on Stop.
- server: localDispatch serves a request in-process through the same
  router (identical wrappers/codecs/error mapping) over an in-memory
  socket — no dial, no pipe, no gob.
- client: LocalDispatch() opt-in. In call(), a unary request whose body and
  response are raw frames (codec/bytes.Frame — the agent/MCP/flow shape)
  dispatches locally; everything else falls back to the network path
  unchanged.

Correctness test proves the fast-path returns byte-identical replies to
the network path; benchmark shows ~545µs -> ~28µs (~20x) and ~3.6x fewer
allocations. Off by default. Covers #4817 (path b); the zero-copy typed
path remains a follow-up.

-The ranked work queue for the autonomous improvement loop. The

-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.

+capability. If an area has had several increments with no user-visible gain, it is done
+for now; rank real-headroom capability instead.

 ## Work queue (ranked)
 
-1. **Fix race in GenerateWithRetry timeout test** ([#4415](https://github.com/micro/go-micro/issues/4415)) — #4411 closed the provider-timeout hardening slice, but the follow-up CI signal shows the new per-attempt timeout coverage has an unsafe test-local counter under `go test -race`. Restore the green evaluator first so the loop can safely continue shipping adoption and harness work.
-2. **Broaden provider streaming conformance** ([#4386](https://github.com/micro/go-micro/issues/4386)) — The blog says Anthropic streaming shipped, but the roadmap still calls for provider-backed streaming across chat and A2A. Add a focused, provider-gated conformance slice so streaming stays end-to-end rather than becoming a one-provider success story.
+### 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._

 ## [Unreleased]
 
+### Added
+- **Gemini streaming support** — the Gemini provider now supports streaming model responses. (`ai/gemini/`)
+- **Model retry jitter controls** — model retry behavior can now use jitter controls to reduce synchronized retry bursts. (`ai/`, `agent/`)
+- **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/`)
+- **A2A inbound AP2 mandate verification (opt-in)** — set `Options.AP2PublicKey` (or `a2a.WithPushURLPolicy`'s sibling `a2a.WithAP2PublicKey` for embedded handlers) and the gateway verifies AP2 payment/checkout mandates carried on incoming messages — signature and task/context binding — recording the outcome in each task's `ap2Verifications`, with the x402 settlement rail carried through for the paid path. Off by default; mandates are otherwise carried unverified. (`gateway/a2a/`)
+- **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 dispatch fast-path (opt-in)** — `client.LocalDispatch()` 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/`)
+
+### 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/`)
+

+## [6.7.0] - July 2026

+- **First-agent chat/inspect fixture** — the maintained first-agent CLI fixture now covers chat and inspect boundaries together. (`internal/harness/`, `cmd/micro/`)
+- **Zero-to-hero inspect transcript check** — the 0→hero harness now verifies the inspect transcript path stays visible in the lifecycle walkthrough. (`internal/harness/zero-to-hero-ci/`, `internal/website/docs/`)

+- **First-agent wayfinding breadcrumbs** — first-agent docs and examples now have locked breadcrumb coverage from the README through the runnable examples. (`README.md`, `internal/website/docs/`, `examples/`)
+- **Offline `micro new` contract** — project scaffolding now has an offline contract so the first service path stays runnable without network access. (`cmd/micro/`, `internal/harness/`)
+
+### Changed

+- **First-agent harness diagnostics** — getting-started harness logs now make first-run and 0→hero failures easier to locate. (`internal/harness/`)
+- **MiniMax streaming conformance** — MiniMax streaming coverage now exercises broader provider conformance behavior. (`ai/minimax/`, `internal/harness/`)

-## Now — hardening
+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.
 
-- **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.
+## Now — capability
 
-## Next — agentic depth
+- **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.
 
-- **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.
+## Next — reach & deployment
 
-## Later
+- **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.
 
-- Memory management (summarization, retrieval/RAG); human-in-the-loop pause/resume;
-  richer A2A live-stream reconnection (`tasks/resubscribe`) and `input-required`
-  handoffs.
+## Later — exploratory
 
-## Developer experience (ongoing)
+- **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).
 
-- 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.
+## 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.

+# 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.

+# 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.
