Judge every priority against the mission: does it make the services → agents → workflows lifecycle simpler, more cohesive, and more operable?

Weight the developer on-ramp and DX — a walkable first-agent tutorial, discoverable examples, docs wayfinding/nav, install friction, debugging, the 0→1 and 0→hero experience — AT LEAST as highly as internal hardening. A developer succeeding on their first agent matters more right now than another conformance/observability/interop increment; do NOT let the queue fill entirely with internal depth work — keep open adoption/on-ramp items near the top. Look at coherence and seams across the core packages (agent, ai, flow, gateway/mcp, gateway/a2a, model, server, store, registry), the dev inner loop (scaffold → run → chat → inspect → deploy), missing pieces, duplication/drift, and realignment.

-
-          CHANGELOG UPKEEP (this is a SAFE factual task — it goes in the auto-merged PR). Keep CHANGELOG.md living, in [Keep a Changelog](https://keepachangelog.com/) format with the newest content at the top under \`## [Unreleased]\`. (a) Enumerate PRs merged to master since the last CHANGELOG update — \`gh pr list --repo $REPO --state merged --base master --limit 60 --json number,title,mergedAt,labels\` — and compare against what CHANGELOG.md already lists. (b) For each genuinely user-facing change not yet recorded (new capability, behavior/API change, notable fix — SKIP purely internal loop/CI/priorities-refresh churn), add a concise entry under the right \`### Added\` / \`### Changed\` / \`### Fixed\` / \`### Documentation\` subheading of \`## [Unreleased]\`, phrased for a user (what it does, which package), not a commit subject. (c) If a new \`v6.MINOR.PATCH\` tag has been cut since the last run (\`git fetch --tags --force\`; compare the newest \`v6.*\` tag to the versions already in CHANGELOG.md), RENAME the current \`## [Unreleased]\` heading to \`## [MINOR.PATCH] - <Month YYYY>\` for that tag and open a fresh empty \`## [Unreleased]\` above it. Keep it accurate — do not invent entries; if nothing user-facing merged, leave [Unreleased] as-is.
-
-          CHANGELOG BLOG POST (blog voice — open a PR but do NOT auto-merge; leave it for the human). If — and only if — enough user-facing work has accumulated since the last changelog post to be worth reading (a meaningful batch, roughly a week's worth; do NOT post an almost-empty update every day), draft a short 'What's new in Go Micro' post that narrates what shipped in plain language (grouped by theme, linking the docs/examples, closing with install/upgrade). Create it as the next-numbered file in \`internal/website/blog/\` (find the highest N, use N+1), mirroring the frontmatter (layout/title/permalink/description) and the post-nav 'previous post' link of the latest existing post, and add an entry at the TOP of \`internal/website/blog/index.html\`. Base it strictly on the CHANGELOG — no speculation.
-
-          THEN do all of these: (A) post a concise findings report as a comment on this issue (#$ISSUE_NUM) — what is aligned, what drifted, what you fixed, the CHANGELOG entries you added, whether you drafted a changelog post (and why / why not), and any other blog ideas. (B) Open ONE auto-merging PR for the SAFE factual work only — coherence/crispness fixes AND the CHANGELOG.md update (NOT brand/marketing/positioning rewrites, NOT the blog post): \`git switch -c codex/devrel-$ISSUE_NUM\`, \`git push -u origin codex/devrel-$ISSUE_NUM\`, \`gh pr create --base master --label codex --title \"<title>\" --body \"<summary, including 'Closes #$ISSUE_NUM'>\"\`, then \`gh pr merge --squash --auto --delete-branch\`. (C) If you drafted a changelog blog post, open it as a SEPARATE PR on its own branch (\`codex/devrel-blog-$ISSUE_NUM\`) with a title prefixed 'blog:' and do NOT enable auto-merge — leave it open for the human to review and merge. Do the same (separate, non-auto-merged PR or just a report note) for any brand/positioning copy. Do not use the make_pr tool (it is a no-op stub). If you touch code, verify go build/test/golangci-lint. Stay out of breaking public-API changes."

 All notable changes to Go Micro are documented here.
 
-Format follows [Keep a Changelog](https://keepachangelog.com/) and versions
-follow [Semantic Versioning](https://semver.org/), matching the git tags and
-[GitHub releases](https://github.com/micro/go-micro/releases) (`v6.MINOR.PATCH`).
-Patch releases are cut automatically as the loop merges improvements; the
-`[Unreleased]` section below is kept current between tags and rolled into the
-next version when it ships.
-
-> Earlier `2026.0x` headings are historical calendar-style markers from before
-> v6 tagging; they are kept for continuity and not reused.
-
----
-
-## [Unreleased]
-
-### Added
-- **`micro loop`** — scaffold an autonomous improvement loop into any repository: GitHub Actions workflows for a planner (keeps a ranked queue), builder (builds the top item as a single-concern PR, auto-merged on green CI), and triage (turns CI failures into fix issues), dispatched to an @mention-driven coding agent. `micro loop init` writes the workflows + `NORTH_STAR`/`PRIORITIES`; `micro loop verify` checks the wiring. This is the loop that maintains go-micro itself, generalized. (`cmd/micro/loop/`)
-
----
-
-## [6.3.12] - July 2026
-
-### Added
-- **Ollama provider** — run agents against open-weight models locally (`/api/chat`, NDJSON streaming) or via Ollama Cloud (OpenAI-compatible `/v1/chat/completions`, SSE), auto-detected from the base URL, with tool calling in both modes. Point any agent at a non-default endpoint with the new `agent.BaseURL` / `micro.AgentBaseURL` option. (`ai/ollama/`, `examples/agent-ollama/`)
-- **Retrieval-backed agent memory** — agents can recall relevant prior turns by similarity, not just the recent window, with a summarizer hook that compacts older history so long conversations stay in budget. (`agent/`)
-- **Scheduled flows** — a flow can run an agent (or any step) on a cron-style schedule, with the dispatch traced end to end. (`flow/`)
-- **Flow verification/grader loop** — a workflow can grade its own step output against a rubric and retry until it passes, plus run-trace analysis to surface where a flow spends its time. (`flow/`)
-- **A2A streaming & continuity** — outbound agent streaming flows through the A2A binding (`message/stream`), with `tasks/resubscribe` and `input-required` handoffs for multi-turn interop. (`gateway/a2a/`)
-
-### Changed
-- **Agent tool-call resilience** — opt-in retries around agent tool calls, and a fallback that executes tool calls emitted as text by weaker models so they still make progress. (`agent/`)
-- **Hardened agent durability** — terminal failure statuses are classified and surfaced, and durable resume-after-restart is covered by tests. (`agent/`)
-
-### Documentation
-- **"Your first agent" walkthrough** and a canonical 0-to-hero reference path, lowering the on-ramp from install to a running agent. (`internal/website/docs/`)
-- **Discord** linked prominently across the README, website nav/footer, and docs. (`https://discord.gg/G8Gk5j3uXr`)

-## How Go Micro is built
-
-Go Micro is developed by an **autonomous improvement loop** — a planner, a
-generator, and a separate evaluator, running as scheduled GitHub Actions with a
-human setting direction. It's the framework's own thesis (an agent operating a
-system) pointed at itself: an agent harness, built by agents. The full process —
-the planner → generator → evaluator pipeline, the correctness-only merge gate, and
-the guardrails — is documented in
-[`internal/docs/CONTINUOUS_IMPROVEMENT.md`](internal/docs/CONTINUOUS_IMPROVEMENT.md).
-Human contributions follow the same gate: green CI, one concern per PR.

 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.

 The gateway's scope system uses `auth.Account` from the go-micro framework. Scopes on accounts are the same `[]string` field used by the framework's `auth.Rules` and `wrapper/auth` package. The gateway stores scope requirements in the default store under `endpoint-scopes/<service>.<endpoint>` keys and checks them on every HTTP request.
 
 For service-level (RPC) auth within the go-micro mesh, use the `wrapper/auth` package which provides `auth.Rules` with priority-based access control. See the [auth wrapper documentation](../../wrapper/auth/README.md) for details.

-## Self-improving loop (`micro loop`)
-
-Turn a repository into a self-improving one: GitHub Actions workflows that
-dispatch a coding agent to plan, build, and triage — gated by CI. This is the
-same loop that maintains go-micro itself, generalized so any repo (and any
-@mention-driven agent) can use it.
-
-```bash
-micro loop init      # scaffold the loop into the current repo
-micro loop verify    # check a repo is wired correctly
-```
-
-`micro loop init` writes three workflows and a queue:
-
-| Role | File | What it does |
-|------|------|--------------|
-| Planner | `.github/workflows/loop-planner.yml` | Keeps a ranked queue in `.github/loop/PRIORITIES.md` |
-| Builder | `.github/workflows/loop-builder.yml` | Builds the top open item as a single-concern PR, auto-merged on green CI |
-| Triage | `.github/workflows/loop-triage.yml` | Turns CI failures into scoped fix issues, back into the queue |
-
-Direction lives in `.github/loop/NORTH_STAR.md` — edit it to steer the loop.
-
-Common flags:
-
-```bash
-micro loop init \
-  --agent @codex \
-  --token-secret LOOP_TOKEN \
-  --branch main \
-  --ci-workflow CI
-```
-
-- `--agent`: how the workflows summon the agent (an `@mention`)
-- `--token-secret`: repo secret holding the driving user PAT
-- `--branch`: base branch for the loop's PRs
-- `--ci-workflow`: `name:` of the CI workflow triage watches
-
-Two things the CLI can't do for you (and `micro loop verify` reminds you of):
-
-1. **Add the token secret.** The agent ignores `@mentions` from the
-   `github-actions` bot, so dispatch posts as a real user via a PAT stored in
-   the `--token-secret` repo secret. The workflows no-op until it's set.
-2. **Set branch protection.** Require the CI checks with **0 approving reviews**
-   so the builder's native auto-merge lands PRs the moment CI is green — that
-   green-CI gate is the loop's only safety mechanism, so keep the suite strong.

-Seed this with a few real items to give the loop a running start, e.g.:

-- **run/chat** with a support agent that uses those services as tools
-- **inspect** the event-driven `intake` flow and approval gate
-- **CI** keeps the deterministic mock-model journey runnable with `go test ./examples/support`
+A real-world support desk — the "zero to hero" shape in one runnable file:
+- **services** (`customers`, `tickets`, `notify`) become the agent's tools automatically
+- **flow** turns a `ticket.created` event into work for the agent (the event is the prompt)
+- **guardrail** — the agent triages freely but can't email a customer without passing the approval gate

-# Durable agent run resume
-
-This example shows the agent-side counterpart to `examples/flow-durable`: an
-agent run is checkpointed with the same `Checkpoint` interface used by flows,
-then resumed after an interruption without repeating a completed side effect.
-The sample uses an in-memory store to keep repeated local runs deterministic;
-use your service store for process-restart recovery.
-
-Run it with:
-
-```sh
-go run ./examples/agent-durable
-```
-
-The demo model calls `inventory.reserve`, then fails to mimic a process dying
-after the tool call was checkpointed. `micro.AgentPending` finds the unfinished
-run and `micro.AgentResume` continues it from the saved checkpoint. The final
-`tool executions: 1` line is the important bit: the reservation tool was not
-called a second time during resume.
-
-## When to use this instead of a durable flow
-
-Use a durable flow when the path is known ahead of time: ordered service calls,
-retries, timers, compensation, and a precise resume stage such as `reserve` or
-`charge`. Use a checkpointed agent run when the path is open-ended and the model
-may choose tools dynamically, but completed tool side effects still must not be
-replayed after a crash or provider failure.
-
-They compose: keep deterministic business process in `flow-durable`, then hand
-off the judgment-heavy step to a checkpointed agent when the workflow needs
-model-directed tool use. Both use the same `Checkpoint` backend, so inspection
-and recovery can share one run-history store.
-
-In a service, use the same pattern at startup:
-
-```go
-pending, _ := micro.AgentPending(ctx, agent)
-for _, run := range pending {
-    _, _ = micro.AgentResume(ctx, agent, run.ID)
-}
-```
-
-`context.Context` cancellation and deadlines are still honored by checkpoint
-loads/saves, model calls, and tool calls. Runs with terminal statuses such as
-`done`, `canceled`, and `expired` are not returned by `AgentPending`.

-A maintained 0-to-hero reference for the Go Micro lifecycle: scaffold a few
-typed services, run them in one process, let an agent chat with those services
-as tools, then inspect the durable flow that triggered the work. It is one
-runnable file and one CI smoke test, so the reference path stays honest as the
-framework evolves.
-
-## The path
-
-1. **Scaffold services** — `customers`, `tickets`, and `notify` are ordinary
-   typed Go Micro services. Their request/response structs and method comments
-   become the tool contract the agent sees.
-2. **Run the harness** — the example starts an in-memory registry, broker,
-   client, store, services, agent, and flow in one process; no external
-   dependencies or API key are required for the default run.
-3. **Chat through an agent** — the `support` agent receives the ticket event as
-   a prompt and calls service tools to look up the customer, triage the ticket,
-   and draft a reply.
-4. **Inspect the workflow** — the `intake` flow records the event-driven run and
-   prints the agent result, showing the service → agent → workflow lifecycle as
-   one runtime.
+A real-world agent built the Go Micro way: a few services, an agent that

 ## Built-in Capabilities
 
 Beyond its scoped service tools, every agent gets two built-in tools. They are not service endpoints — they are capabilities the agent has over itself and over other agents. They are plain tools wired into the agent's tool handler; there is no separate harness, loop engine, or graph. The LLM calls them exactly like any other tool.

-harness pattern ([Anthropic on harness design](https://www.anthropic.com/engineering/harness-design-long-running-apps)) —
-a planner, a generator, and a *separate* evaluator — distributed across GitHub
-Actions instead of subagents. Each role is a workflow:
-
-| Role | Workflow (action name) | What it does |
-|------|------------------------|--------------|
-| **Planner** | `loop-architect.yml` — *Loop: Architect (Planner)* | Tracks live state, prioritizes the roadmap + an internal scan, and maintains the ranked queue in [`PRIORITIES.md`](PRIORITIES.md). Decides *what*. |
-| **Generator** | `loop-builder.yml` — *Loop: Builder (Generator)* | Builds the top open queue item as a single-concern PR (via Codex) and self-merges on green CI. Does the work. |
-| **Evaluator** | `harness.yml` — *Harness (E2E)*, plus the CI gate (`tests.yaml`, `lint.yaml`) | Grades every change: the mock harness + unit/lint on each push/PR, and real-model conformance hourly. A *separate* grader — never the generator judging itself. |
-| **Evaluator → feedback** | `loop-triage.yml` — *Loop: Triage (Evaluator feedback)* | On harness failure, root-causes, dedupes, and files scoped fix issues back into the planner's queue. The hill-climbing feedback path. |
-| **Coherence** | `loop-devrel.yml` — *Loop: DevRel* | Keeps README/website/docs/blog aligned with the North Star, keeps `CHANGELOG.md` living (reconciling `[Unreleased]` against merged PRs and rolling it into version headings as tags cut), and drafts the changelog blog post. |
-| **Release** | `loop-release.yml` — *Loop: Release (daily patch)* | Cuts a daily patch tag when master has new commits, so the *installable* framework tracks the loop's improvements (triggers `release.yml`/goreleaser). Minor/major bumps stay with the human. |
