roadmap: drop the word "bets" (development, not bets) (#4792 )
Per standing preference — this is planned development/capability, not "bets". Reword ROADMAP.md and .github/loop/PRIORITIES.md accordingly; no change to what the loop builds. Claude-Session: https://claude.ai/code/session_01CmdEY7pYmV5zzwCjNJ4ykL Co-authored-by: Claude <noreply@anthropic.com>

 # 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.

+**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.

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

 ## Work queue (ranked)

-1. **Surface AtlasCloud tool results when the follow-up reply is empty** ([#3735](https://github.com/micro/go-micro/issues/3735)) — PR #3738 closed the prior A2A streaming fallback blocker (#3560), and the latest live provider run exposed the next adoption-critical Now-phase conformance seam: AtlasCloud can execute the tool but return an empty assistant follow-up, leaving first-agent/provider conformance with a blank reply instead of the deterministic tool result. Fixing this keeps the service-as-tool story dependable before chasing deeper harness parser work.
-2. **Require AtlasCloud notification side effects in multi-step harnesses** ([#3736](https://github.com/micro/go-micro/issues/3736)) — after the basic tool-result path is reliable, the multi-step universe and plan/delegate harnesses must not accept provider replies that claim completion while skipping the required notify/delegate side effect. This protects the services → agents → workflows lifecycle promised by the first-agent and 0→hero paths: an agent should operate the system, not only narrate success.
-3. **Parse multi-event A2A SSE fallback responses in the harness** ([#3662](https://github.com/micro/go-micro/issues/3662)) — once the current AtlasCloud tool/side-effect failures are resolved, the harness must accept legitimate multi-event `message/stream` responses instead of concatenating valid SSE events into invalid JSON. This remains a small CI-verifiable harness fix that keeps cross-provider streaming conformance focused on real gateway failures rather than parser brittleness.
-4. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — the highest-value remaining resilience gap is predictable failure semantics across agent runs, model calls, tool calls, plan/delegate, and flow handoffs. Tool retries, live-provider deadline tuning, and delegated-plan completion are in place; the lifecycle still needs cancellation/deadline propagation so work fails safely instead of becoming opaque loops.
-5. **Emit OpenTelemetry spans for agent run timelines** ([#3525](https://github.com/micro/go-micro/issues/3525)) — recent work made runs inspectable, correlated trace metadata through scheduled dispatch, verified restart resume, added opt-in tool retries, hardened provider conformance, and fixed provider-emitted text tool calls. The next Next-phase step is to turn that RunInfo foundation into standard OTel spans for agent runs, model calls, tool calls, checkpoint/resume, cancellation/deadlines, and failures.
-6. **Add an AP2 mandate layer over A2A and x402** ([#3552](https://github.com/micro/go-micro/issues/3552)) — this is a forward interop investment, not a Now-phase blocker: Go Micro already has A2A agents and x402 paid tools, so a small signed-mandate foundation can keep agent payments aligned with the open-protocol story without pulling the queue away from adoption, resilience, or observability. Keep it additive and opt-in while the AP2/FIDO work settles.
+### Capability — the headline (roadmap: Now / Next)

-_Seeded by Claude Code from the roadmap + open issues; thereafter maintained by the
-architecture-review pass._
+1. **Agents that pay — wire the x402 buyer into the agent runtime** ([#4786](https://github.com/micro/go-micro/issues/4786)) — the flagship. The buyer `x402.Client`/`Payer`/budget already exists; wire it so an agent autonomously settles a payment-required tool within budget and retries, opt-in and observable. Makes go-micro a runtime for autonomous agent commerce.
+2. **Agent spend observability** ([#4787](https://github.com/micro/go-micro/issues/4787)) — surface x402 spend in `RunInfo` and OpenTelemetry so payments are inspectable like every other agent action. (Follows #4786.)
+3. **Example: an agent that pays for a paid tool** ([#4788](https://github.com/micro/go-micro/issues/4788)) — the runnable artifact that makes it real for a developer, against a mock facilitator (no live funds). (Follows #4786/#4787.)
+4. **gRPC-reflection MCP** ([#4796](https://github.com/micro/go-micro/issues/4796)) — expose external reflected gRPC services as MCP tools, not only go-micro-native handlers. A large jump in what agents can operate without requiring teams to rewrite existing services.
+5. **Kubernetes operator + CRDs foundation** ([#4797](https://github.com/micro/go-micro/issues/4797)) — add the first opt-in `Agent`, `Service`, and `Flow` resource foundation so the services → agents → workflows lifecycle has a native deployment path for Kubernetes users.
+
+### 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, and provider-failure inspection. 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.

+GO-MICRO ATTACK SURFACE — weight these:
+- **MCP gateway** (`gateway/mcp`) and **A2A gateway** (`gateway/a2a`) — untrusted input from agents/tools: auth/scope enforcement, injection into downstream RPC, SSRF via tool/agent URLs, rate-limit/circuit-breaker bypass, info leak in errors.
+- **x402 payments** (`wrapper/x402`) — payment verification and settlement: signature/mandate validation, replay, budget-reservation races, facilitator auth (CDP bearer) handling, amount/network confusion.
+- **Auth** (`auth/jwt`, `wrapper/auth`) — token validation, algorithm confusion, scope/priority rule bypass, missing checks on endpoints.
+- **AI providers** (`ai/*`) — base-URL and endpoint handling: SSRF via config-controlled `BaseURL`, API keys leaking into logs/errors, TLS verification.
+- **Agent tool loop** (`agent/`) — prompt injection reaching real tool calls, guardrail (`MaxSteps`/`LoopLimit`/`ApproveTool`) bypass, delegate/plan side effects.
+- **Trust boundaries** — `server` RPC handlers, `broker` consumers, `store`/`registry` inputs, `transport` TLS defaults (v6 verifies by default — confirm nothing regressed).
+- **The loop itself** — `.github/workflows/loop-*.yml`: the `CODEX_TRIGGER_TOKEN` PAT must never be echoed/leaked; workflow inputs must not enable script injection.
+- **Dependencies** — run `govulncheck ./...` (install if needed) and inspect `go.mod` for known CVEs.

+HOW TO REPORT:
+- **Known/public dependency CVEs**: file a `security` issue referencing the CVE + module; you MAY open a PR bumping to the patched version. Do NOT enable auto-merge.
+- **Novel, exploitable vulnerabilities in this code** (not yet public): do NOT post an exploit or PoC in a public issue. File a CONCISE `security` + `needs-human` issue naming the class, location (file/function), and impact only — and note it should go through GitHub private vulnerability reporting. Do NOT open a public fix PR that reveals it.
+- **Low-risk hardening**: a normal `security` issue is fine.
+
+NEVER auto-merge a security change. Never weaken a control to make a test pass. Architectural/breaking fixes → `needs-human` with the tradeoff.

+
+### Changed
+- **First-agent CLI next steps** — CLI output now points new users toward the maintained first-agent path after scaffold/run milestones. (`cmd/micro/`)
+
+### Fixed
+- **Plan/delegate completion** — plan-delegate runs now preserve completed steps, guard ordering, require notify-before-completion, and stabilize checkpoint continuation paths. (`agent/`, `internal/harness/`)

+## [6.3.14] - July 2026
+
+### Added
+- **MiniMax provider** — run agents against MiniMax's `MiniMax-M3` model via its OpenAI-compatible endpoint, with tool calling and streaming; auto-detected from the base URL. (`ai/minimax/`)
+- **`micro loop` security role** — a new opt-in loop role (`--roles …,security`) that periodically audits a repo for vulnerabilities and files `security` issues. It is deliberately conservative: it never auto-merges fixes and never publishes exploit detail in public issues (responsible disclosure), and risky fixes are marked `needs-human`. go-micro now runs it against its own attack surface (MCP/A2A gateways, x402, auth, provider URLs, agent tool loop, deps). (`cmd/micro/loop/`)
+- **Agent run tracing** — agent model streaming and run-event kinds now emit richer trace detail for debugging agent execution. (`agent/`)
+
+### Changed
+- **Agent memory** — streamed agent replies are persisted in conversation memory so later turns can reference streamed responses. (`agent/`)
+
+### Fixed
+- **Plan/delegate completion** — agents now continue unfinished plan steps more reliably, fail checkpointed runs that leave delegated plans unfinished, recover from unknown plan-delegate tool calls, avoid duplicate side effects, and complete timeout paths deterministically. (`agent/`)
+- **AtlasCloud tool calls** — streaming and request fallback handling now recovers tool-call results from provider responses that omit the expected structured fields. (`ai/atlascloud/`)
+- **Agent preflight diagnostics** — provider setup failures now surface more actionable errors before an agent run starts. (`agent/`)
+- **A2A fallback streams** — fallback stream validation is stricter for malformed or incomplete A2A streaming responses. (`gateway/a2a/`)
+- **File-store test isolation** — file-store expiry and table tests are less timing-sensitive and isolate their state more reliably. (`store/file/`)
+
+### Documentation
+- **First-agent debugging path** — docs now include no-secret transcript checkpoints, durable resume examples, and clearer CLI/website wayfinding for first-agent debugging. (`README.md`, `internal/website/docs/`, `examples/agent-durable/`)
+
+---
+
+## [6.3.13] - July 2026
+
 ### Added
 - **`micro loop`** — scaffold an autonomous improvement loop into any repository: GitHub Actions workflows dispatched to an @mention-driven coding agent, across up to five roles — `planner` (ranked queue), `builder` (top item as a single-concern PR, auto-merged on green CI), `triage` (CI failures → fix issues), and opt-in `coherence` (docs/CHANGELOG alignment) and `release` (daily patch tag). Each dispatch role's instruction lives in an editable `.github/loop/prompts/<role>.md` file — the workflow is the mechanism, the prompt is the policy — so a repo customizes behavior without forking the CLI. `micro loop init --roles …` writes it all; `micro loop verify` checks the wiring. This is the loop that maintains go-micro itself, generalized. (`cmd/micro/loop/`)

+### Changed
+- **x402 payments** — settlement now covers CDP facilitator authentication and conformance edge cases. (`wrapper/x402/`)
+
+### Fixed
+- **Plan/delegate harnessing** — side effects and notifications are now idempotent and deterministic across duplicate, alias, order-scoped, and reachability scenarios. (`agent/`, `internal/harness/`)
+
+### Documentation
+- **First-agent on-ramp** — quickstart docs now connect the no-secret first-agent transcript, example map, and 0→hero path. (`README.md`, `internal/website/docs/`)
+- **Ollama provider docs** — the provider surface, capability matrix, and examples now document local and cloud behavior. (`internal/website/docs/`, `examples/agent-ollama/`)

-## 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.

+Use this when scaffold -> run -> chat -> inspect stalls and you want the
+smallest provider-free recovery loop before reading the full docs.
+
+1. Confirm prerequisites before starting the gateway:
+   micro agent preflight
+
+2. Start the project and keep it running in a separate terminal:
+   micro run
+
+3. Check the agent is registered and the chat gateway is reachable:
+   micro agent doctor
+
+4. If chat returns an answer or an error, inspect the latest run state:
+   micro inspect agent <name>
+   micro runs <name>
+
+5. If provider chat is not configured yet, prove the no-secret path still works:
+   micro agent demo
+   go test ./internal/harness/zero-to-hero-ci -run TestNoSecretFirstAgentTranscript -count=1
+   go test ./internal/harness/zero-to-hero-ci -run TestNoSecretFirstAgentDebuggingSmoke -count=1
+
+Recovery docs:
+  https://go-micro.dev/docs/guides/debugging-agents.html
+  https://go-micro.dev/docs/guides/no-secret-first-agent.html`
+
+const noSecretDemoHelp = `No-secret first-agent demo
+
+Use this when you want the fastest provider-free agent success path before
+configuring API keys. It runs the maintained support/first-agent transcript with
+the deterministic mock model used by CI:
+
+  go test ./internal/harness/zero-to-hero-ci -run TestNoSecretFirstAgentTranscript -count=1
+
+What this proves:
+  - service tools can be called by an agent
+  - chat behavior is exercised without contacting a live provider
+  - run history can be inspected after the prompt
+  - the debug smoke seeds a stalled-first-agent recovery transcript
+
+After it passes:
+  - Build your own service-backed agent: https://go-micro.dev/docs/guides/your-first-agent.html
+  - Diagnose provider-backed chat:     https://go-micro.dev/docs/guides/debugging-agents.html
+  - Walk the full 0→hero lifecycle:    https://go-micro.dev/docs/guides/zero-to-hero.html
+
+Use live-provider chat when you are ready for real model behavior:
+  micro agent preflight  # before micro run: prerequisites
+  micro run
+  micro chat
+  micro agent doctor     # after micro run: chat/gateway/inspect recovery
+  micro inspect agent <name>
+
+Debug transcript smoke:
+  go test ./internal/harness/zero-to-hero-ci -run TestNoSecretFirstAgentDebuggingSmoke -count=1`

+The SECURITY prompt — the editable policy for the security role. The workflow
+prepends the agent @mention and substitutes __ISSUE__ before posting. Keep
+__ISSUE__ literal.
+
+Security is deliberately more conservative than the other roles: it does NOT
+auto-merge fixes, and it does NOT publish exploit details in public issues.
+-->
+Act as the security reviewer for this repository. Audit for real, exploitable vulnerabilities — do not pad the report with theoretical or low-value lint-style noise.
+
+WHAT TO LOOK FOR: injection (SQL/command/template), authentication and authorization bypass, credential/secret/token exposure (in code, logs, or error messages), SSRF and unsafe outbound requests (especially user- or config-controlled URLs), path traversal, unsafe deserialization, missing or incorrect input validation on trust boundaries (HTTP handlers, RPC endpoints, message consumers), insecure defaults (TLS, auth, permissions), unsafe use of `crypto`/randomness, and known-vulnerable dependencies (run `govulncheck ./...` if available, or inspect `go.mod`).
+
+DEDUPE against open issues before filing anything.
+
+HOW TO REPORT — this matters:
+- **Known/public dependency CVEs** (already disclosed): file an issue labeled `security` referencing the CVE and the affected module, and you MAY open a PR that bumps the dependency to the patched version. Do **NOT** enable auto-merge — leave it for human review.
+- **Novel, exploitable vulnerabilities in this codebase** (not yet public): do **NOT** post a working exploit, proof-of-concept, or step-by-step reproduction in a public issue — that is irresponsible disclosure. File a CONCISE issue labeled `security` and `needs-human` that names the vulnerability *class*, the *location* (file/function), and the *impact*, with only enough detail for a maintainer to find it — and note it should be handled via the repository's private vulnerability reporting if the repo is public. Do NOT open a public fix PR that reveals the vulnerability; leave the fix to a human.
+- **Low-risk hardening** (defense-in-depth, missing validation with no proven exploit): a normal `security` issue is fine.
+
+NEVER auto-merge a security change. Never weaken a control to make a test pass. Anything requiring an architectural or breaking change: label it `needs-human` and describe the tradeoff.
+
+Post a summary as a comment on this issue (#__ISSUE__) — how many findings by severity, what you filed, and what needs a human — then close it (`gh issue close __ISSUE__`). If you open a dependency-bump PR, do it yourself from the shell: `git switch -c loop/security-__ISSUE__`, `git push -u origin loop/security-__ISSUE__`, `gh pr create --base << .DefaultBranch >> --title "<title>" --body "<summary, Closes #__ISSUE__>"` — then STOP; do NOT run `gh pr merge --auto`. Do not use a make_pr tool.

+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

+# First Agent
+
+This is the smallest runnable service-backed agent in the repository. It sits
+between `micro new helloworld` and the full [`examples/support`](../support/)
+0→hero reference.
+
+It runs with a deterministic mock model, so you do not need `ANTHROPIC_API_KEY`,
+`OPENAI_API_KEY`, or any other provider secret.
+
+```bash
+go run ./examples/first-agent
+```
+
+Expected transcript:
+
+```text
+First agent (provider: mock, no API key)
+> Summarize my next steps
+  [notes] listed starter notes
+assistant: Your first agent read the notes service and found three steps: install the CLI, run a service, then chat with an agent.
+✓ service-backed agent completed without provider secrets
+```
+
+## What it demonstrates
+
+- `notes` is a normal Go Micro service with one RPC method.
+- `assistant` is an agent scoped to that service via `agent.Services("notes")`.
+- The mock model requests the service tool through the normal agent tool handler.
+- The final answer proves the service → agent path without a live model key.
+
+CI keeps this path runnable with:
+
+```bash
+go test ./examples/first-agent
+```
+
+## Next chat, inspect, and debug breadcrumbs
+
+This example exits after one in-process `assistant.Ask` call so it stays tiny and
+provider-free. When you move from this transcript to a long-running agent, keep
+these commands nearby:
+
+```bash
+micro run
+micro chat assistant --prompt "Summarize my next steps"
+micro inspect agent assistant
+micro agent doctor assistant
+```
+
+Use the [no-secret first-agent guide](../../internal/website/docs/guides/no-secret-first-agent.md)
+to compare this transcript with the CLI demo, then keep the
+[debugging guide](../../internal/website/docs/guides/debugging-agents.md) open for
+preflight, doctor, inspect, and history checks. After that, continue to
+[`examples/support`](../support/) for the full services → agents → workflows
+lifecycle with a flow trigger and an approval gate.
