Asim Aslam db4401d306 client/service: rename the in-process fast-path to Local + service knob (#4855)
goreleaser / goreleaser (push) Waiting to run
Renames the fast-path option to the cleaner Local across the stack (it's
still unreleased) and adds a service-level knob:

- client.Local() (was client.LocalDispatch) enables the in-process
  fast-path; Options.Local is the field. The internal/network package it
  dispatches through is the "local network".
- service.Local() (aliased micro.Local()) turns it on for a whole
  service's client in one place — every co-located unary call (agent tool
  calls, flow dispatch, gateway -> service) takes the fast-path, no
  per-call wiring. Same o.Client.Init(...) pattern the Broker option uses.

Off by default; a no-op for distributed deployments since the fast-path
falls back to the network for anything not co-located.

Asim Aslam 08a3edcff4 client/server: in-process dispatch fast-path (opt-in) (#4854)
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.

Asim Aslam 1250d33f86 deploy/kubernetes: dependency-light reconcile core (alpha) (#4853)
Adds Reconcile(desired, observed) — the pure decision an operator's
reconcile loop runs: given a desired Agent/Service/Flow resource and the
observed cluster state, it returns the one action to converge (create /
update / noop) plus Ready/Error status conditions.

No controller-runtime, no client-go: the decision is a pure function of
desired + observed, so it's fully unit-testable without a cluster. A
future operator binary supplies Observed from the live cluster and applies
the Action; only that adapter needs the Kubernetes client — keeping the
heavy dependency out of the core module.

Covers #4842 (Option B). Tests: create-when-absent, noop-when-matched-and-
ready, update-on-drift, progressing-when-under-replicated, error-on-invalid
-spec.

Asim Aslam 7e2346b8c8 flow: human-in-the-loop pause/resume (durable workflow, stage A) (#4852)
Adds a waiting run state so a flow step can suspend for external input
and resume durably — stage A of the durable-agentic-workflow design in
#4816.

- flow.Await(key, prompt) / flow.AwaitStep(...): a StepFunc that suspends
  the run. runFrom recognizes the signal, checkpoints the run with status
  "waiting" (recording what it awaits), and returns cleanly — a suspend is
  not a failure, and it is not retried or graded.
- Flow.ResumeWith(ctx, runID, input): completes the awaited step with the
  injected input (which becomes that step's output state) and continues
  from the next step.
- Flow.Waiting(ctx): lists suspended runs with their Await metadata.
- ResumePending/Pending skip waiting runs — they need input, not a
  restart. Existing crash-resume (Resume) is unchanged.

Additive: no signature or default-behavior changes. Await ergonomics
(sentinel-return) are the default proposed in #4816; open to AwaitStep-kind
instead if preferred.

Asim Aslam 6733d0c7c4 a2a: verify inbound AP2 mandates into the paid path (opt-in) (#4851)
The AP2 primitives (checkout/payment mandates, Ed25519 sign/verify, the
x402 rail reference, attach-to-message) already existed, but the gateway
only *carried* mandates on the resulting task — it never verified them, so
ap2Verifications was never populated and a downstream paid path had no
trust signal.

Wire opt-in verification: set Options.AP2PublicKey (gateway) or
a2a.WithAP2PublicKey (embedded handler) and each mandate carried on a task
is verified (signature + task/context binding) with the result recorded in
task.AP2Verifications; the x402 settlement rail rides along for the paid
path. Off by default — mandates stay carried-but-unverified — so no payment
trust decision enters the default flow.

Adds a gateway integration test driving a real message/send that carries a
signed x402 payment mandate (verified, rail carried; tampered → surfaced as
unverified) plus a default-path test proving carry-only is unchanged.

Asim Aslam bbeb3ac920 a2a: guard push-notification callbacks against SSRF (#4849)
The A2A gateway's push-notification flow (tasks/pushNotificationConfig/set
→ deliverPush) POSTed task state to a caller-supplied URL via the default
HTTP client, so an untrusted A2A caller could aim the gateway at internal
addresses (loopback, link-local cloud metadata, RFC1918) it would
otherwise never reach — a server-side request forgery vector (#4129).

Add a default SSRF-safe policy: only http/https callbacks whose host does
not resolve to a loopback, private, link-local, multicast, or unspecified
address. It's enforced when the config is set (caller gets a clear
rejection, nothing stored) and again at delivery, and the delivery client
re-checks the resolved IP at dial time so a name that passes validation
can't be rebound to an internal address before connect.

Operators that need a trusted in-cluster receiver set Options.AllowPushURL
(gateway) or a2a.WithPushURLPolicy (embedded handlers) to own the policy;
that path skips the built-in private-IP dial guard by design.

Tests cover blocked/allowed URLs, the dial-time guard, set-time rejection,
default-deny delivery, and the operator override.

Asim Aslam aaa03f89e3 deploy/kubernetes: embed CRDs instead of duplicating them (#4845)
goreleaser / goreleaser (push) Waiting to run
The CRD manifests were kept in two places — real YAML under config/crd/
(for kubectl apply) and byte-identical const strings in manifests.go
(for the Go CRDManifests map) — which will silently drift.

Make config/crd/*.yaml the single source of truth and go:embed it;
CRDManifests now reads the embedded bytes. Drops ~120 lines of
duplicated YAML, no behavior change (still stdlib-only, tests unchanged).

Asim Aslam 1f5ae1f39a loop: pause automatic runs while we do focused fixes (#4843)
Comment out the automatic triggers on every loop workflow so the
autonomous engine stops firing on its own while we land the current
round of fixes 1:1:

- planner / builder / coherence / security / release: drop the cron
  schedules (no more hourly/daily/weekly runs, no nightly auto-release).
- triage: drop the workflow_run trigger so CI failures no longer
  auto-dispatch agent tasks.

Each keeps workflow_dispatch, so any loop can still be run on demand,
and re-enabling is just uncommenting the trigger. No prompts, tokens, or
logic changed — only when the workflows fire.

Asim Aslam 6950870dd9 a2a: conform to external A2A clients — well-known path + spec SSE events (#4832)
* a2a: conform to external A2A clients — well-known path + spec SSE events

The A2A gateway interoperated go-micro-to-go-micro but a real external
client (ADK, LangGraph, a2a-SDK) would not:

- Discovery: served the Agent Card at /.well-known/agent.json, but A2A
  0.3.0 discovers it at /.well-known/agent-card.json. Serve both, with
  agent-card.json canonical and agent.json a legacy alias — per-agent,
  per-skill, and at the single-agent top level.

- message/stream emitted repeated full Task snapshots. External SSE
  clients parse by `kind` and stop on `final:true`; a Task snapshot has
  neither, so they never terminate. Emit spec-shaped TaskArtifactUpdate
  (append) chunks and close with a TaskStatusUpdate final:true. The
  non-streaming and resubscribe paths also close with a terminal marker.

- A streaming error set both `result` and `error` in one JSON-RPC
  response (strict clients reject it). Emit a failed status-update
  instead — never result and error together.

Tests assert the canonical card path, the status-update/artifact-update
event shapes ending in final:true, and that no response carries both
result and error.

* harness: update a2a-streaming to the spec-shaped stream events

The A2A gateway now emits artifact-update deltas and a terminal
status-update (final:true) instead of repeated full Task snapshots, so
the conformance harness must reassemble the answer from the append
artifact-update chunks and assert the final:true marker. This makes the
harness a stronger spec check rather than a snapshot-shape check.

* agent: update a2a stream test to spec-shaped events

TestA2AStreamUsesAgentChatPathWithTools decoded the last SSE event as a
completed Task snapshot with artifacts. The gateway now closes the stream
with a status-update (final:true) and carries the answer as append
artifact-update deltas, so reassemble the answer from those deltas and
assert the terminal completed status-update instead.

Asim Aslam 7e3d2d3b13 x402: harden spend cap — reject invalid amounts, require settler option (#4831)
Two spend-safety fixes from the gap audit (#4814):

- Client.Do refused a 402 only on the budget check, but parsed
  maxAmountRequired with a swallowed error, so a non-decimal, overflowing
  or negative amount became 0 and passed the cap trivially while Payer.Pay
  still signed against the string. Now reject any amount that is not a
  positive integer before signing.

- Require settled only when the facilitator implemented Settler; a
  verify-only facilitator served the resource while no funds moved. Add
  Config.RequireSettlement to fail closed in that case.

Tests cover invalid/negative/overflow amounts and the verify-only
fail-closed path.

Asim Aslam 1b83cdff9c mcp: stdio/ws tool results are JSON + isError (fixes garbage to Claude Desktop) (#4825)
Closes #4813. The stdio transport is the path an external MCP host (Claude
Desktop) uses, and it emitted broken output:
- tool results were `fmt.Sprintf("%v", decodedJSON)` → Go map-syntax
  (`map[id:1 name:bob]`), not JSON. Now returned as JSON text.
- tool-execution failures were returned as JSON-RPC protocol errors; per the
  MCP spec they must be a result with `isError:true` so the agent can read the
  failure. Now they are (span/audit still record the error).

Both fixes are shared between stdio and websocket via a new `mcpToolResult`/
`mcpToolError` (dedupes the two transports). Added the missing stdio round-trip
tests (the package had zero) proving JSON output and the isError contract, using
an injected fake client; updated the websocket auth tests that asserted the old
protocol-error-on-tool-failure behavior.

Also fixes a pre-existing golangci-lint failure on master (unnecessary
`string(...)` conversion in grpcreflect.go from #4821) so the mcp package lints
clean — another one the required-checks gap let through.

Asim Aslam db31341b30 roadmap: restock with capability bets; repoint the loop queue (#4790)
The last-100-commit assessment found the loop producing busy-work — but the root
cause was the roadmap: every forward item was hardening/conformance/docs-polish,
no net-new capability. The loop was faithfully executing a maintenance backlog.

Restock the roadmap with real capability bets and demote maintenance to explicit
background:
- Now: agents that pay (wire the existing x402 buyer into the agent runtime);
  AP2 mandate foundation over A2A+x402 (#3552).
- Next: gRPC-reflection MCP; Kubernetes operator + CRDs.
- Later: the runtime-fitness loop (live Mu + operator/canary); HTTP/3; A2A
  reconnection; memory/RAG.
- Ongoing: hardening/conformance/DX, capped so it never crowds out capability.

Repoint .github/loop/PRIORITIES.md to rank the capability bets at the top, with
the flagship decomposed into buildable issues (#4786 buyer wiring, #4787 spend
observability, #4788 example), so the loop pulls real work instead of grooming
itself.

Asim Aslam 85374c6401 loop: cut planner bookkeeping churn + cap diminishing-returns conformance work (#4731)
An assessment of the last 100 commits found ~45% were pure "refresh planner
priorities" bookkeeping and much of the rest was thrashing on one weak provider
(AtlasCloud text-tool-call repair) and guarding docs the loop already wrote —
motion, not progress. Two prompt-policy fixes:

PLANNER (planner.md):
- Default to NOT committing. Post the assessment and close the issue; open a
  PRIORITIES.md PR ONLY when the change is MATERIAL (top item changes, an item
  is added/removed, or a top item's issue closed). No PRs for reorders below
  the top, reword, or "keep it current" — that churn was the loop's #1 waste.
- Add a diminishing-returns guard: don't queue the Nth doc-guard or the Nth
  robustness workaround for an already-tolerated class; mark exhausted areas
  needs-human and rank real-headroom capability instead.

TRIAGE (triage.md):
- Cap the AtlasCloud/plan-delegate tail-chase: another instance of a class the
  agent already tolerates is NOT filed as a routine patch — comment "recurred —
  capped" and, if worth more, needs-human. Real regressions (lint/tests/
  govulncheck on master) and genuinely new defects still get filed.

Prompt-only; reversible. Steers the loop toward outcomes over busy-work.

Asim Aslam 50fc743b6d ai: remove the ai/flow backward-compat shim (#4653)
`ai/flow` was an alias-only package re-exporting go-micro.dev/v6/flow (the
canonical location). It had no callers anywhere in the repo. Remove it; users
should import `go-micro.dev/v6/flow` directly (identical types/functions).

Classified as a Removed (breaking) change in the CHANGELOG since it deletes a
public import path — see the PR for the versioning note.

Asim Aslam 98cbafd11a docs(loop): formalize the agent-agnostic mention model (#4559)
The loop's dispatch is agent-agnostic already — `--agent` just sets the
@mention it posts, so any coding agent that responds to an issue @mention and
opens a PR works. Make that explicit instead of implying Codex-only:

- micro-loop guide: add a "Choosing an agent" section — Codex (default), Claude
  Code (via anthropics/claude-code-action responding to @claude), any other
  mention-driven agent, and an honest note that assignment-triggered agents
  (e.g. Copilot's coding agent) aren't supported by the mention dispatch yet.
- Clarify the `--agent` help text and the CLI README bullet.

No behavior change — the mention model already covers Codex and Claude; this
documents it and scopes the one real gap (an "assign" adapter) honestly.

Asim Aslam bba3b8ba98 ci: add govulncheck vulnerability gate (+ wire into loop triage) (#4558)
Adds a deterministic reachable-CVE gate: `govulncheck ./...` on every push/PR,
failing on any reachable vulnerability EXCEPT an explicit allow-list of
known-unfixable ones. Today the allow-list holds exactly the two pgx/v4 CVEs
(GO-2026-5004, GO-2026-4518) with no upstream fix (tracked in #4556), so the
gate is green now and turns red the moment a NEW vulnerability appears.

This is the deterministic layer under the `security` loop role: the role
audits with judgment, this blocks known CVEs mechanically. Also adds
`govulncheck` to the loop-triage watch list, so a newly-disclosed CVE that
reddens the gate on master auto-files a fix issue for the loop to bump the dep.

Make `govulncheck` a required status check on master to enforce it.
Verified locally: exit 3 with only the two allow-listed IDs -> gate PASS.

Asim Aslam 2cf95b27c8 security: patch reachable CVEs (28 of 30) via toolchain + dependency bumps (#4555)
govulncheck reported 30 reachable vulnerabilities. Remediation:
- Pin `toolchain go1.25.12` and build CI on Go 1.25 (lint/tests workflows):
  clears ~24 Go standard-library CVEs (crypto/tls, crypto/x509, net/http,
  html/template, net/url, os, …) that were present under go1.24.7.
- Bump `golang.org/x/net` v0.38.0 -> v0.55.0 and `google.golang.org/grpc`
  v1.71.1 -> v1.79.3 (grpc raises the module's Go directive to 1.25).

Result: govulncheck drops from 30 -> 2. The remaining two
(github.com/jackc/pgx/v4, github.com/jackc/pgproto3/v2) have no upstream fix
and require a pgx v5 migration — tracked separately; the govulncheck gate will
follow with those explicitly allow-listed until migrated.

Note: this raises go-micro's minimum Go to 1.25 (forced by the grpc security
bump). Verified: build, go vet, and the ai/agent/flow/store/registry/broker/
wrapper/cmd + grpc/net-dependent packages pass on 1.25.12.

# Priorities
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.
The ranked work queue for the autonomous improvement loop. The **planner** owns
this file: each run it turns the [roadmap](../../ROADMAP.md) plus an internal scan
into a single ordered list — highest-value first — each item linked to a tracking
issue. The **builder** works the top item whose issue is still open. So the
planner decides *what*, the builder *builds* it.
**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.
**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.
**Off-limits to the loop** (the architect proposes these as notes, never as queue
items the loop can auto-merge): brand/positioning copy, breaking public-API
changes, architectural rewrites. Those go to the human.

## Work queue (ranked)
1. **Handle AtlasCloud plan-delegate partial tool calls** ([#4431](https://github.com/micro/go-micro/issues/4431)) — A current live conformance failure can let AtlasCloud/minimax stop at a partial XML-style tool call, so delegation never produces the required task/notify side effects. This is the highest Now-phase risk because plan/delegate is the core services → agents → workflows seam and must fail or recover deterministically across providers.
2. **Verify first-agent docs wayfinding stays in lockstep** ([#4441](https://github.com/micro/go-micro/issues/4441)) — Developer adoption remains the current goal after the 0→1/0→hero harness landed. Keep README, website guides, examples, and CLI breadcrumbs aligned so the no-secret first-agent path stays discoverable instead of becoming a stale documentation promise.
3. **Fix AtlasCloud tool streaming capability mismatch** ([#4438](https://github.com/micro/go-micro/issues/4438)) — The provider matrix currently advertises AtlasCloud streaming capability beyond its tool-streaming implementation, causing the live agent streaming conformance path to run an unsupported assertion. Fixing the capability/implementation seam keeps streaming honest without blocking no-secret adoption work.
4. **Broaden provider streaming conformance** ([#4386](https://github.com/micro/go-micro/issues/4386)) — Once the provider-specific AtlasCloud mismatch is resolved, expand the broader streaming matrix so chat, agent RPC, and A2A streaming regressions are caught across keyed providers while local CI continues to skip cleanly without secrets.
### 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._

CURRENT GOAL — developer adoption: weight the on-ramp (walkable first-agent tutorial, discoverable examples, docs wayfinding, install friction, debugging, 0→1 and 0→hero) at least as highly as internal hardening; do not let the queue fill entirely with internal depth work.

(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>"`.
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.
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`. If the queue is already accurate, just close this issue (`gh issue close __ISSUE__`).
(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). For any prioritized gap with no issue, file one: `gh issue create --label codex --label enhancement --title "<scoped task>" --body "<goal, scope, acceptance criteria>"`.
Do NOT make breaking public-API or architectural changes yourself — surface those in the assessment as notes for the human, never as auto-merged changes. Open the PR yourself from the shell with `gh`; do not use the make_pr tool (it is a no-op stub).
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. When a PR IS warranted: `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`.

Read the logs and root-cause each distinct failure. DEDUPE hard against open AND recently-closed issues — if a failure matches an existing or recurring one, comment "recurred" on that issue rather than filing a new one.
For each genuine, self-contained defect, file a scoped issue (`gh issue create --label codex --label enhancement --title "<scoped fix>" --body "<root cause, where, acceptance criteria>"`) so the increment loop builds it and the next CI/harness run verifies it. A lint or test failure on master is a real regression — file it so it is fixed promptly; do NOT ignore it.
WHAT TO FILE:
- **Lint, Run Tests, or govulncheck failing on master** — a real regression. File a scoped issue (`gh issue create --label codex --label enhancement --title "<scoped fix>" --body "<root cause, where, acceptance>"`) so it is fixed promptly.
- **A genuinely NEW, distinct provider-conformance defect** — file it.
IGNORE only genuine transient flakes — live-model latency, provider outages, rate limits, network timeouts with no code cause (mostly relevant to the harness). Anything needing a breaking or architectural change: file it as `needs-human` and describe it, rather than auto-queuing it as a routine fix.
WHAT NOT TO FILE (this cap matters):
- **Another instance of a class the agent already tolerates** — a weak provider (e.g. AtlasCloud) emitting malformed / text-rendered / partial tool calls, or another plan/delegate notify/side-effect edge case. These have been hardened repeatedly with diminishing returns. Do NOT auto-file yet another routine robustness patch. Comment "recurred — repeated class, capped" on the nearest existing issue and, if it seems genuinely worth more investment, label it `needs-human` for a human to decide. The loop should not keep chasing one weak provider's output shape.

## [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 "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/`)

## [6.7.0] - July 2026
### Added
- **A2A streaming conformance harness** — A2A streaming behavior is now covered by focused conformance checks. (`gateway/a2a/`, `internal/harness/`)
- **Agent x402 spend budget guardrail** — agents now have spend budget guardrails for x402-paid tool calls. (`agent/`, `gateway/`)
- **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/`)
### Changed
- **Agent stream run context propagation** — agent streams now preserve run context through streaming paths for more complete tracing and inspection. (`agent/`)
- **Postgres store pgx v5 migration** — the Postgres store now uses pgx v5. (`store/postgres/`, `go.mod`)
- **Plan-delegate plan persistence** — plan/delegate runs now persist plan state more defensively across harness scenarios. (`agent/`, `internal/harness/`)
### Fixed
- **Nested tool-call markup rejection** — agent argument parsing now rejects nested tool-call markup instead of accepting ambiguous tool input. (`agent/`)
- **Retry cancellation during backoff** — retry backoff now respects cancellation more reliably. (`agent/`, `ai/`)
- **Plan-delegate mock recovery regression gate** — the harness now catches plan/delegate mock recovery regressions before they ship. (`internal/harness/`, `agent/`)

- **Function-style text tool calls** — agent fallback parsing now recognizes provider replies that render tools as function-style calls, including nested JSON arguments. (`agent/`)
- **Plan/delegate notify recovery** — plan-delegate recovery now waits for recovered notify side effects and routes retries through the communications agent that owns the notification. (`internal/harness/`)

Go Micro is an **agent harness** and service framework for Go.
**Community:** questions, ideas, or just want to build alongside us? [Join the Discord](https://discord.gg/G8Gk5j3uXr).
## Overview
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.

5. Battle-tested: works across every provider, fails safely, observable.
## 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
## Shipped agent 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** — opt-in `Checkpoint` support lets agent `Ask` and
streaming runs persist, list pending work, and resume without replaying completed
tool calls. Human-input pauses resume through explicit input helpers.
- **Agent observability** — agent `RunInfo` now feeds OpenTelemetry spans/events
across runs, model turns, tool calls, retries, delegation lineage, and resume
checkpoints.
## Next — reach & deployment
## Next — agentic depth
- **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.
- **Streaming** — broaden provider-backed `ai.Stream` coverage and keep chat/A2A streaming end to end.
- **Resume operations polish** — keep improving CLI/docs breadcrumbs for finding
pending agent runs and deciding whether to call resume, resume-input, or stream
resume in production.
- **Observability hardening** — keep span attributes and run inspection coherent
across agents, flows, and gateways as more providers and workflow paths are
exercised.
## Later — exploratory
## Later
- **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.
- 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.
