Refresh planner queue for 4710

.github/loop/PRIORITIES.md

@@ -21,7 +21,10 @@ changes, architectural rewrites. Those go to the human.
 
 ## Work queue (ranked)
 
-1. **Add CLI continuation for input-required agent runs** ([#4755](https://github.com/micro/go-micro/issues/4755)) — #4750 closed the cancellation/deadline propagation gap and there are no open codex PRs in flight. Do not re-queue more docs-link checks, AtlasCloud-specific text repair, or plan/delegate edge hardening for now; those areas have had several recent increments. The next highest-value user-facing gap is making human-in-the-loop pauses operable from the scaffold → run → chat → inspect path: list an `input-required` run, provide the missing input from the CLI, and inspect the completed run without requiring a developer to write a Go resume helper.
+1. **Verify 0-to-hero lifecycle transcript in CI** ([#4711](https://github.com/micro/go-micro/issues/4711)) — #4707 closed the first-agent wayfinding contract, so the highest-value Now-roadmap adoption gap moves to the full 0→hero services → agents → workflows lifecycle. The README, website, and v6.6.0 story now promise scaffold → run → chat → inspect → flow history → deploy dry-run as one walkable path; make that transcript a no-secret CI contract so the on-ramp cannot drift while internals keep hardening.
+2. **Add first-agent debugging golden transcript coverage** ([#4712](https://github.com/micro/go-micro/issues/4712)) — Developer adoption still depends on recovery, not just happy-path setup. The CLI now points users through `micro agent demo`, quickcheck/debug, examples, chat, and inspect; verify those outputs against the maintained first-agent example so a new user who stalls can recover without learning package internals. Keep this scoped to docs/CLI contract coverage, not command redesign.
+3. **Gate mock provider plan-delegate resume scenarios** ([#4713](https://github.com/micro/go-micro/issues/4713)) — #4709 closed the live AtlasCloud nested tool-call rejection gap, but the underlying agent-loop risk remains valuable enough to keep near the top: completed plan steps, notifications, unsafe fallback parsing, and resume semantics must stay deterministic without provider keys. Capture the recent provider failures in mock-based regression coverage before broadening into live-provider conformance.
+4. **Migrate store/postgres from pgx/v4 to pgx/v5** ([#4556](https://github.com/micro/go-micro/issues/4556)) — Security upkeep matters to the service-framework half of the harness, and #4556 is the remaining open enhancement/security item. Keep it below the adoption and agent-loop contracts because it is narrower than the current developer-adoption goal, but do not let reachable dependency risk drift indefinitely.

-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: 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`.

-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`.

+4. `micro zero-to-hero` - print the maintained one-command no-secret lifecycle harness and runnable examples.
+5. **[Examples wayfinding index](https://github.com/micro/go-micro/blob/master/examples/INDEX.md)** - choose the smallest no-secret first-agent, maintained **[0→hero support reference](https://github.com/micro/go-micro/tree/master/examples/support)**, and next interop examples from one map.
+6. **[Smallest first-agent example](https://github.com/micro/go-micro/tree/master/examples/first-agent)** - run a mock-model, no-secret agent before adding provider keys.
+7. **[No-secret first-agent transcript](guides/no-secret-first-agent.html)** - run a useful support agent with a mock model before setting up a provider key.
+8. **[Your First Agent](guides/your-first-agent.html)** - turn this service into an agent-callable tool, chat with it, and learn the `micro agent preflight` → `micro run` → `micro chat` loop.
+9. **[Debugging your agent](guides/debugging-agents.html)** - use `micro inspect agent <name>` to inspect service registration, tool calls, run history, memory, provider failures, and flow handoffs when the agent does something surprising.
+10. **[0→hero Reference](guides/zero-to-hero.html)** - walk the maintained scaffold → run → chat → inspect → deploy dry-run path that proves services, agents, and workflows together.
