 ## Work queue (ranked)
 
-1. **Add end-to-end streaming chat conformance** ([#4738](https://github.com/micro/go-micro/issues/4738)) — #4736 closed the pgx/v5 security-upkeep item, and there are no open codex PRs in flight. The next highest-value user-visible gap is streaming chat that works coherently across the agent/CLI/A2A path, starting with a no-secret harness and extending to keyed provider checks without another provider-specific malformed-output workaround.
+1. **Fix atlascloud A2A stream fallback marker validation** ([#3832](https://github.com/micro/go-micro/issues/3832)) — #3834 closed the plan/delegate timeout by classifying the provider timeout, and the latest live-provider red is now a narrower atlascloud A2A streaming fallback case: the task completes but the artifact text omits the marker the harness expects. Keep this first because the getting-started contract depends on dependable interop diagnostics across chat, tools, and A2A; the fix should make the validator assert a stable protocol-level invariant or make the marker deterministic without relying on brittle free-form model text.
+2. **Propagate agent run cancellation and deadlines through model and tool calls** ([#3544](https://github.com/micro/go-micro/issues/3544)) — once the remaining live-provider harness drift is stabilized, the highest-value Now-phase resilience gap is predictable failure semantics across agent runs, model calls, tool calls, plan/delegate, and flow handoffs. Tool retries, live-provider timeout classification, delegated-plan completion, side-effect enforcement, and file-store isolation are in place; the lifecycle still needs cancellation/deadline propagation so work fails safely instead of becoming opaque loops.
+3. **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, fixed provider-emitted text tool calls, and narrowed the latest provider failures to diagnosability/contract gaps. 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.
+4. **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.

-AVOID DIMINISHING-RETURNS CHURN — this is the most important judgment you make. Before ranking anything, ask: *would a real user notice this, or is it the loop grooming itself?* Do NOT queue: another regression-guard/breadcrumb/"verify the docs stay linked" test around docs the loop already wrote; the Nth robustness workaround for a weak provider's malformed output (e.g. AtlasCloud text-tool-call repair) once the agent already tolerates that class; another variation of a subsystem that has been hardened several times recently (e.g. plan/delegate notify/side-effect edge cases). If an area has had several increments with no user-visible gain, it is DONE for now — mark further work there `needs-human` and rank something with real headroom instead (new capability in gateway/flow/model/store, interop depth, observability). A full queue is not the goal; a queue of things that matter is.
+(3) MAINTAIN THE QUEUE in `.github/loop/PRIORITIES.md` — a SINGLE ordered list, highest-value first, each item linking a scoped, CI-verifiable issue (#N); roadmap phase is the primary ordering, internal findings (cohesion gaps, DX friction, missing pieces) interleaved by value. For any prioritized gap with no issue, file one: `gh issue create --label codex --label enhancement --title "<scoped task>" --body "<goal, scope, acceptance criteria>"`.

-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.

-Act as the security reviewer for go-micro. Audit for real, exploitable vulnerabilities — skip theoretical or lint-style noise.
-
-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.
-
-DEDUPE against open issues first.
-
-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.
-
-Post a summary as a comment on this issue (#__ISSUE__) — findings by severity, what you filed, what needs a human — then close it (`gh issue close __ISSUE__`). If you open a dependency-bump PR: `git switch -c loop/security-__ISSUE__`, `git push -u origin loop/security-__ISSUE__`, `gh pr create --base master --label codex --label security --title "<title>" --body "<summary, Closes #__ISSUE__>"` — then STOP, do NOT run `gh pr merge --auto`.

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.
-- **Transient flakes** — live-model latency, provider outages, rate limits, network timeouts with no code cause. Ignore.
-- **Anything needing a breaking or architectural change** — label `needs-human` and describe it.
+IGNORE only genuine transient flakes — live-model latency, provider outages, rate limits, network timeouts with no code cause (mostly relevant to the harness).

-
-### 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/`)

-repository? `micro loop` scaffolds the autonomous improvement loop used by Go
-Micro itself: a North Star, ranked issue queue, role prompts, GitHub Actions

-```bash
-micro loop init --roles all
-micro loop verify

-Before turning on the schedule, configure a dispatch token such as
-`CODEX_TRIGGER_TOKEN`, protect the default branch with required CI checks
-(`go build ./...`, `go test ./...`, and `golangci-lint run ./...` for this
-repository), and seed `.github/loop/PRIORITIES.md` with one scoped issue per
-increment. See the [`micro loop` quickstart](internal/website/docs/guides/micro-loop.md)

-- **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

 ## Next — agentic depth
 
+- **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.
-- **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.

-<!--
-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.

-## Recommended adoption path

-1. **First service:** run [`hello-world`](./hello-world/) to learn service
-   registration, handlers, client calls, and health checks.
-2. **First agent:** run [`first-agent`](./first-agent/) with
-   `go run ./examples/first-agent`; it uses a deterministic mock model and needs
-   no provider key.
-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
-   external AI clients.
-5. **Workflow depth:** use [`flow-durable`](./flow-durable/) once the agent path
-   needs checkpointed, resumable deterministic work.

-# 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.
