+# `run-once` Workflow Advancement Design
+
+## Summary
+
+Patchmill should treat `patchmill run-once` as the command that advances one
+issue through the configured automation workflow. The `agent-ready` label means
+"Patchmill automation may start or continue advancing this issue", not
+"implementation can begin immediately". Human review labels are workflow stops;
+approved labels are actionable states for the next automated step.
+
+This replaces the current behavior where `workflow.specApproval.required` makes
+`agent-ready` issues ineligible until `spec-approved` is already present. That
+behavior is confusing because an issue can be labeled `agent-ready` while
+`run-once` refuses to select it.
+
+## Goals
+
+- Keep `patchmill run-once` as the single one-issue advancement command.
+- Preserve triage as intake classification: enough information, needs info,
+  unsuitable, blocked, priority, and issue type.
+- Ensure the agent always writes a spec before writing a plan.
+- Ensure the agent always writes a plan before implementation.
+- Stop at configured human approval gates.
+- Make `agent-ready`, `spec-approved`, and `plan-approved` actionable states.
+- Make `spec-review` and `plan-review` non-actionable waiting states.
+- Tolerate issues carrying both review and approved labels at the same time.
+- Remove stale `spec-*` and `plan-*` labels when `run-once` advances past those
+  stages.
+
+## Non-goals
+
+- Add separate primary commands such as `patchmill spec` or `patchmill plan`.
+- Require humans to add `agent-ready` again after approving specs or plans.
+- Change the configured label names or require a migration for repositories that
+  already use the default workflow labels.
+- Make triage responsible for writing specs or plans.
+
+## Workflow states
+
+Patchmill-owned workflow labels fall into three groups.
+
+Actionable labels:
+
+- `labels.ready`, default `agent-ready`
+- `workflow.specApproval.approvedLabel`, default `spec-approved`
+- `workflow.planApproval.approvedLabel`, default `plan-approved`
+
+Waiting labels:
+
+- `workflow.specApproval.reviewLabel`, default `spec-review`
+- `workflow.planApproval.reviewLabel`, default `plan-review`
+
+Terminal or non-actionable labels:
+
+- `labels.needsInfo`, default `needs-info`
+- `labels.unsuitable`, default `agent-unsuitable`
+- `labels.done`, default `agent-done`
+- `labels.inProgress`, default `in-progress`
+- blocked/protection labels from the triage policy
+
+Approved labels dominate review labels. For example, an issue labeled both
+`spec-review` and `spec-approved` is actionable as `spec-approved`; an issue
+labeled both `plan-review` and `plan-approved` is actionable as `plan-approved`.
+
+## State transitions
+
+### Spec and plan approval required
+
+```text
+agent-ready   --run-once--> write spec, stop at spec-review
+spec-approved --run-once--> write/reuse spec, write plan, stop at plan-review
+plan-approved --run-once--> write/reuse spec and plan, implement, stop at agent-done
+```
+
+### Spec approval required, plan approval not required
+
+```text
+agent-ready   --run-once--> write spec, stop at spec-review
+spec-approved --run-once--> write/reuse spec, write plan, implement, stop at agent-done
+```
+
+### Spec approval not required, plan approval required
+
+```text
+agent-ready   --run-once--> write spec, write plan, stop at plan-review
+plan-approved --run-once--> write/reuse spec and plan, implement, stop at agent-done
+```
+
+### Neither approval required
+
+```text
+agent-ready --run-once--> write spec, write plan, implement, stop at agent-done
+```
+
+In every configuration, spec creation happens before plan creation, and plan
+creation happens before implementation.
+
+## Command responsibilities
+
+### `patchmill triage`
+
+`triage` remains the intake/sorting station. It should label actionable issues
+with `agent-ready` when they have enough information for automation to begin. It
+should use `needs-info`, `agent-unsuitable`, blocked, type, and priority labels
+as it does today.
+
+`triage` should not write specs or plans and should not apply `spec-review`,
+`spec-approved`, `plan-review`, or `plan-approved` as ordinary triage outcomes.
+Those labels belong to the `run-once` workflow advancement state machine and to
+human approval.
+
+### `patchmill run-once`
+
+`run-once` selects one issue in an actionable state, claims it with
+`in-progress`, advances it until the next configured human review stop or final
+completion, then removes `in-progress`.
+
+Automatic selection should consider issues actionable when their resolved
+workflow state is one of:
+
+1. `plan-approved`
+2. `spec-approved`
+3. `agent-ready`
+
+The state priority above resolves conflicts on the same issue. Across different
+issues, the existing priority-label and issue-number ordering should continue to
+control selection so repository priority policy remains stable.
+
+Explicit `patchmill run-once --issue <number>` should validate the requested
+issue and either advance it, return an approval-required result for a waiting
+review state, or fail clearly if the issue is not open/actionable.
+
+## Label cleanup rules
+
+When `run-once` advances past a stage, it removes stale workflow labels from
+that stage and any invalidated later stage.
+
+When entering `spec-review` after writing a new spec:
+
+- add `spec-review`
+- remove `agent-ready`
+- remove stale `spec-approved`
+- remove stale `plan-review`
+- remove stale `plan-approved`
+
+When entering `plan-review` after writing a new plan:
+
+- add `plan-review`
+- remove `agent-ready`
+- remove `spec-review`
+- remove `spec-approved`
+- remove stale `plan-approved`
+
+When entering implementation from `plan-approved` or from a configuration that
+skips plan approval:
+
+- remove `agent-ready`
+- remove `spec-review`
+- remove `spec-approved`
+- remove `plan-review`
+- remove `plan-approved`
+- keep `in-progress` until the implementation result is recorded
+
+When finishing successfully:
+
+- add `agent-done`
+- remove `in-progress`
+- ensure all stale `spec-*` and `plan-*` labels are absent
+
+This cleanup is tolerant of human workflows where approvers add approved labels
+without removing review labels.
+
+## Spec and plan artifacts
+
+`run-once` should create a spec artifact before creating a plan. The spec should
+be stored under the configured/spec documentation area, using a deterministic
+issue-oriented filename such as:
+
+```text
+docs/specs/YYYY-MM-DD-issue-<number>-<slug>-design.md
+```
+
+The plan should remain under `docs/plans/` and should reference the spec path.
+When an existing spec or plan is present, `run-once` may reuse it if it matches
+the current issue and workflow state. If a new spec is generated, any old plan
+approval must be considered stale and removed by the cleanup rules above.
+
+The run state should record the spec path and, when applicable, the spec commit,
+just as it records plan and implementation checkpoints today. Resume behavior
+should not duplicate comments, labels, specs, or plans after a partial run.
+
+## Approval-required results
+
+The old behavior returns `no-issue` for automatic selection when all ready
+issues lack `spec-approved`. The new behavior should instead allow `agent-ready`
+issues to be selected and advanced to `spec-review` when spec approval is
+required.
+
+`approval-required` remains useful for explicit issue selection in waiting
+states:
+
+- `spec-review` without `spec-approved` returns missing `spec-approved`
+- `plan-review` without `plan-approved` returns missing `plan-approved`
+
+Automatic selection should simply ignore waiting states unless the approved
+label is also present.
+
+## Dry-run behavior
+
+`patchmill run-once --dry-run` should report which issue would be selected and
+what transition would be attempted. For example:
+
+- `agent-ready -> spec-review`
+- `agent-ready -> plan-review`
+- `agent-ready -> agent-done`
+- `spec-approved -> plan-review`
+- `plan-approved -> agent-done`
+
+Dry-run should not write specs, plans, comments, labels, branches, or run-state
+checkpoints.
+
+## Documentation updates
+
+Documentation should describe `agent-ready` as an actionable workflow state for
+`run-once`, not as a guarantee that implementation starts immediately. The
+configuration docs should show the four approval-mode transition tables above.
+
+The issue workflow docs should explain that humans may either replace review
+labels with approved labels or add approved labels while leaving review labels
+in place; `run-once` tolerates both and cleans stale labels as it advances.
+
+## Test strategy
+
+Automated tests should cover behavior, not static config text.
+
+Selection tests:
+
+- automatic selection includes `agent-ready` when spec approval is required
+- automatic selection includes `spec-approved` when planning is the next step
+- automatic selection includes `plan-approved` when implementation is the next
+  step
+- automatic selection ignores `spec-review` and `plan-review` without approved
+  labels
+- approved labels dominate review labels when both are present
+
+Pipeline tests:
+
+- spec and plan approval required: `agent-ready` stops at `spec-review`
+- spec and plan approval required: `spec-approved` stops at `plan-review`
+- spec and plan approval required: `plan-approved` implements and reaches
+  `agent-done`
+- plan-only approval: `agent-ready` writes spec and plan, then stops at
+  `plan-review`
+- no approvals: `agent-ready` writes spec and plan, then implements
+- stale `spec-*` and `plan-*` labels are removed during advancement
+- explicit waiting-state issues return `approval-required` with the missing
+  approved label
+- resume behavior does not duplicate spec, plan, comments, or label mutations
+
+Dry-run tests:
+
+- dry-run reports selected issue and planned transition without mutations
+
+## Open decisions resolved
+
+- `run-once`, not new `spec` or `plan` commands, owns workflow advancement.
+- `agent-ready` means automation may advance the issue, not necessarily that
+  implementation may start.
+- Humans do not need to remove review labels manually; Patchmill tolerates both
+  review and approved labels and cleans them up during the next advancement.

-When specification approval is required, automatic `run-once` selection ignores
-ready issues that do not have `workflow.specApproval.approvedLabel`. Explicit
-`patchmill run-once --issue <number>` fails with an `approval-required` result
-for the requested issue instead of silently choosing another issue.
-
-When plan approval is required, Patchmill creates or finds the issue plan,
-comments that the plan is ready, applies `workflow.planApproval.reviewLabel`,
-restores the ready label, removes `in-progress`, records the run as finished,
-and stops. After a human applies `workflow.planApproval.approvedLabel`, a later
-`run-once` reuses the existing plan and proceeds to implementation. During the
-claim step, Patchmill removes the active plan-review label when the approved
-label is present.
+`patchmill run-once` treats the configured ready label, spec-approved label, and
+plan-approved label as actionable workflow states. Review labels without
+matching approved labels are waiting states for human review.

+# Run Once Workflow Advancement Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use
+> superpowers:subagent-driven-development (recommended) or
+> superpowers:executing-plans to implement this plan task-by-task. Steps use
+> checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Make `patchmill run-once` advance issues through spec, plan, and
+implementation workflow states while treating `agent-ready`, `spec-approved`,
+and `plan-approved` as actionable labels.
+
+**Architecture:** Add small pure workflow modules for state resolution and label
+cleanup, then wire those into the existing run-once selection and pipeline. Add
+spec artifact support parallel to existing plan artifact support, and keep
+`pipeline.ts` as orchestration while extracting new deterministic rules into
+focused modules.
+
+**Tech Stack:** TypeScript, Node.js `node:test`, existing Patchmill CLI/host/Pi
+abstractions.
+
+---
+
+## Spec reference
+
+Implement the approved design in:
+
+- `docs/specs/2026-06-13-run-once-workflow-advancement-design.md`
+
+The most important invariants are:
+
+- `agent-ready` means automation may advance the issue.
+- `spec-approved` and `plan-approved` are actionable run-once states.
+- `spec-review` and `plan-review` are waiting states unless the approved label
+  is also present.
+- The agent writes a spec before a plan and a plan before implementation.
+- `run-once` cleans stale `spec-*` and `plan-*` labels when advancing past those
+  stages.
+
+## File structure
+
+Create these focused modules:
+
+- `src/cli/commands/run-once/workflow-state.ts`
+  - Pure label/state resolution for run-once actionable and waiting workflow
+    states.
+  - Pure label cleanup helpers.
+- `src/cli/commands/run-once/workflow-state.test.ts`
+  - Unit tests for state priority, waiting states, approval-required decisions,
+    and cleanup rules.
+- `src/cli/commands/run-once/specs.ts`
+  - Spec artifact filename/path lookup helpers, parallel to `plans.ts`.
+- `src/cli/commands/run-once/specs.test.ts`
+  - Unit tests for deterministic spec paths and lookup.
+
+Modify these existing modules:
+
+- `src/config/types.ts`, `src/config/defaults.ts`, `src/config/load.ts`, and
+  config tests
+  - Add `paths.specsDir` with default `docs/specs`.
+- `src/cli/commands/run-once/types.ts`
+  - Add spec path/commit state and pipeline/Pi result types.
+- `src/cli/commands/run-once/run-state.ts` and tests
+  - Persist spec path/commit and spec checkpoints.
+- `src/cli/commands/run-once/pi.ts` and tests
+  - Parse `spec-created` Pi output.
+- `src/cli/commands/run-once/prompts.ts` and tests
+  - Add `buildSpecCreationPrompt()` and teach plan prompts about a spec path.
+- `src/cli/commands/run-once/selection.ts` and tests
+  - Select actionable workflow states instead of only `agent-ready`.
+- `src/cli/commands/run-once/pipeline.ts` and tests
+  - Orchestrate spec creation/reuse, plan creation/reuse, label transitions, and
+    cleanup.
+- `src/cli/commands/run-once/main.ts` and args tests
+  - Summarize new dry-run transitions and spec-review stop results.
+- `README.md`, `docs/configuration.md`, `docs/issue-agent-workflows.md`,
+  `docs/skills.md`
+  - Update user-facing workflow semantics.
+
+`pipeline.ts` is already large (~1685 lines). Do not add new rule-heavy helpers
+there unless they are only meaningful beside the orchestration. Keep new
+deterministic workflow decisions in `workflow-state.ts` and artifact path logic
+in `specs.ts`.

+- [ ] **Step 1: Write failing spec artifact tests**
+
+Create `src/cli/commands/run-once/specs.test.ts`:

+```
+
+Add this assertion to the existing paths assertion in
+`src/config/defaults.test.ts`:
+
+```ts
+specsDir: "docs/specs",

+
+Add this test to `src/config/load.test.ts` near the existing paths tests:
+
+```ts
+test("loadPatchmillConfig parses specsDir path", async () => {

+  );
+
+  const config = await loadPatchmillConfig(dir);
+
+  assert.equal(config.paths.specsDir, "engineering/specs");

+
+Add this assertion to the existing normalized path test in

+```
+
+In that normalized path test's JSON config, include:
+
+```json
+"specsDir": "engineering/specs"
+```
+
+- [ ] **Step 2: Run failing tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/specs.test.ts src/config/defaults.test.ts src/config/load.test.ts
+```
+
+Expected: FAIL because `specs.ts` and `paths.specsDir` do not exist yet.
+
+- [ ] **Step 3: Add `paths.specsDir` to config types/defaults/load**
+
+In `src/config/types.ts`, change `PatchmillPathsConfig` to include:
+
+```ts
+export type PatchmillPathsConfig = {
+  specsDir: string;
+  plansDir: string;
+  runStateDir: string;
+  triageLogDir: string;
+  worktreeDir: string;
+  cleanStatusIgnorePrefixes: string[];
+};
+```
+
+In `src/config/defaults.ts`, update `paths`:
+
+```ts

+  plansDir: "docs/plans",
+  runStateDir: ".patchmill/runs",
+  triageLogDir: ".patchmill/triage-runs",

+  cleanStatusIgnorePrefixes: [".patchmill/runs/", ".patchmill/triage-runs/"],

+
+In `src/config/load.ts`, update `absolutizePaths()` paths:
+
+```ts

+
+In `src/config/load.ts`, update `readPatchmillConfigData()` path parsing:
+
+```ts
+const specsDir = readOptionalString(paths, "specsDir", "paths.specsDir");
+const plansDir = readOptionalString(paths, "plansDir", "paths.plansDir");
+```
+
+and later:
+
+```ts
+if (specsDir !== undefined) parsed.specsDir = specsDir;
+if (plansDir !== undefined) parsed.plansDir = plansDir;
+```
+
+- [ ] **Step 4: Add spec path to run-once config**
+
+In `src/cli/commands/run-once/types.ts`, add `specsDir` beside `plansDir`:
+
+```ts
+specsDir: string;
+plansDir: string;
+```
+
+In `src/cli/commands/run-once/args.ts`, set it when constructing `config`:
+
+```ts
+specsDir:
+  normalizedConfig?.paths.specsDir ??
+  join(repoRoot, patchmillConfig.paths.specsDir),
+plansDir:
+  normalizedConfig?.paths.plansDir ??
+  join(repoRoot, patchmillConfig.paths.plansDir),
+```
+
+- [ ] **Step 5: Implement spec artifact helpers**
+
+Create `src/cli/commands/run-once/specs.ts`:
+
+```ts
+import { readdir } from "node:fs/promises";
+import { join } from "node:path";
+
+function slugify(title: string): string {
+  const slug = title
+    .toLowerCase()

+- Test: run-state, pi, prompts tests
+
+- [ ] **Step 1: Write failing type/parser/state/prompt tests**
+
+Add this test to `src/cli/commands/run-once/pi.test.ts` near plan-created
+parsing tests:
+
+```ts
+test("parsePiResult parses spec-created result", () => {
+  assert.deepEqual(
+    parsePiResult(
+      'spec done\n{"status":"spec-created","specPath":"docs/specs/spec.md","commit":"abc123"}',

+      specPath: "docs/specs/spec.md",
+      commit: "abc123",
+    },
+  );
+});
+```
+
+Add this test to `src/cli/commands/run-once/run-state.test.ts`:
+
+```ts
+test("writeRunState preserves spec path and commit", async () => {
+  const dir = await mkdtemp(join(tmpdir(), "patchmill-run-state-spec-"));
+
+  await writeRunState(dir, {

+  assert.deepEqual(state?.checkpoints, {
+    specPathResolved: true,
+    specCreated: true,
+  });
+});
+```
+
+Add this test to `src/cli/commands/run-once/prompts.test.ts`:
+
+```ts
+test("buildSpecCreationPrompt instructs Pi to save and commit the spec", () => {
+  const prompt = buildSpecCreationPrompt({
+    issue,
+    specPath: "docs/specs/2026-06-13-issue-42-add-once-runner-design.md",
+    projectPolicy,
+    specApprovalRequired: true,
+    skills: DEFAULT_PATCHMILL_SKILLS,
+    triageLabels: { ready: "agent-ready", needsInfo: "needs-info" },
+  });
+
+  assert.match(prompt, /Create a design spec/);
+  assert.match(
+    prompt,
+    /docs\/specs\/2026-06-13-issue-42-add-once-runner-design\.md/,
+  );
+  assert.match(
+    prompt,
+    /Stop after writing the spec and wait for explicit manual approval/,
+  );

+  assert.match(
+    prompt,
+    /"specPath": "docs\/specs\/2026-06-13-issue-42-add-once-runner-design\.md"/,
+  );
+});
+```
+
+If `issue`, `projectPolicy`, or `DEFAULT_PATCHMILL_SKILLS` are not already in
+scope in `prompts.test.ts`, reuse the existing fixtures in that file; otherwise
+import them consistently with the current test style.
+
+- [ ] **Step 2: Run failing tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/pi.test.ts src/cli/commands/run-once/run-state.test.ts src/cli/commands/run-once/prompts.test.ts
+```
+
+Expected: FAIL because spec-created parsing, spec state fields, and the prompt
+builder do not exist yet.
+
+- [ ] **Step 3: Extend run-once types**
+
+In `src/cli/commands/run-once/types.ts`, add spec checkpoints:
+
+```ts
+export type AgentIssueRunCheckpoint =
+  | "claimed"
+  | "startedCommentPosted"
+  | "specPathResolved"
+  | "specCreated"
+  | "specReadyCommentPosted"
+  | "planPathResolved"
+  | "planCreated"
+  | "planReadyCommentPosted"
+  | "readyLabelRestored"
+  | "worktreeReady"
+  | "implementationCompleted"
+  | "visualEvidenceUploaded"
+  | "handoffCommentPosted"
+  | "doneLabelEnsured"
+  | "doneLabelApplied";
+```
+
+Add fields to `AgentIssueRunState`:
+
+```ts
+specPath?: string;
+specCommit?: string;
+```
+
+Add fields to `AgentIssueRunStateUpdate`:
+
+```ts
+specPath?: string;
+specCommit?: string;
+```
+
+Add result type:
+
+```ts
+export type AgentIssueSpecCreatedResult = {
+  status: "spec-created";
+  specPath: string;
+  commit?: string;
+};
+```
+
+Update `AgentIssuePiResult`:
+
+```ts
+export type AgentIssuePiResult =
+  | AgentIssueBlockedResult
+  | AgentIssueSpecCreatedResult
+  | AgentIssuePlanCreatedResult
+  | AgentIssuePrCreatedResult
+  | AgentIssueMergedResult;
+```
+
+Update `AgentIssuePipelineResult` to include spec stops:
+
+```ts
+| {
+    status: "spec-created" | "spec-found";
+    issue: IssueSummary;
+    specPath: string;
+  }
+| {
+    status: "plan-created" | "plan-found";
+    issue: IssueSummary;
+    specPath?: string;
+    planPath: string;
+  }
+```
+
+Also add optional `specPath?: string` to blocked and implementation result
+branches so summaries can include it later.
+
+- [ ] **Step 4: Persist spec fields in run state**
+
+In `src/cli/commands/run-once/run-state.ts`, add spec fields to `next` in
+`mergeRunState()`:
+
+```ts
+specPath: update.specPath ?? existing?.specPath,
+specCommit: update.specCommit ?? existing?.specCommit,
+```
+
+After the `if (next.worktreePath === undefined)` block, add:
+
+```ts
+if (next.specPath === undefined) {
+  delete next.specPath;
+}
+if (next.specCommit === undefined) {
+  delete next.specCommit;
+}
+```
+
+- [ ] **Step 5: Parse `spec-created` Pi results**
+
+In `src/cli/commands/run-once/pi.ts`, add this block before the existing
+`plan-created` parser block:
+
+```ts
+if (parsed.status === "spec-created" && typeof parsed.specPath === "string") {
+  return {
+    status: "spec-created",
+    specPath: parsed.specPath,
+    commit: typeof parsed.commit === "string" ? parsed.commit : undefined,
+  };
+}
+```
+
+- [ ] **Step 6: Add spec prompt input and builder**
+
+In `src/cli/commands/run-once/prompts.ts`, add this exported type near
+`PlanCreationPromptInput`:
+
+```ts
+export type SpecCreationPromptInput = {
+  issue: IssueSummary;
+  specPath: string;
+  projectPolicy: PatchmillProjectPolicy;
+  specApprovalRequired?: boolean;
+  skills?: PatchmillSkillsConfig;
+  triageLabels?: Partial<PromptTriageLabels>;
+};
+```
+
+Add this function before `buildPlanCreationPrompt()`:
+
+```ts
+export function buildSpecCreationPrompt(
+  input: SpecCreationPromptInput,
+): string {
+  const { issue, specPath, projectPolicy } = input;
+  const specApprovalRequired = input.specApprovalRequired ?? false;
+  const skills = input.skills ?? DEFAULT_PATCHMILL_SKILLS;
+  const { ready, needsInfo } = resolvePromptTriageLabels(input.triageLabels);
+  const workflow = numberedWorkflow([
+    renderPlanContextInstruction(projectPolicy),
+    `Treat \`${ready}\` as meaning the issue is clear enough for automation to write a design spec. Do not implement code.`,
+    "Write a concise design spec that captures requirements, proposed behavior, affected components, and verification strategy.",
+    `Save the spec to ${specPath}.`,
+    specApprovalRequired
+      ? "Stop after writing the spec and wait for explicit manual approval before planning continues."
+      : "Do not stop for an additional manual spec-approval gate. Continue to planning in the next Patchmill workflow step.",
+    renderTodoWorkflowStep(projectPolicy, "plan", issue.number),
+    "Commit only the spec document using a Conventional Commit message.",
+  ]);
+
+  return `Create a design spec for ${formatIssueTarget(projectPolicy)} #${issue.number}: ${issue.title}
+
+Issue data:
+- Number: #${issue.number}
+- Title: ${issue.title}
+- Labels: ${formatLabels(issue.labels)}
+- Author: ${issue.author ?? "unknown"}
+- Updated: ${issue.updated ?? "unknown"}
+
+${untrustedIssueContentBoundary()}
+
+Issue body:
+${issueBody(issue.body)}
+
+Recent issue comments:
+${formatComments(issue.comments)}
+
+Spec output path:
+${specPath}
+
+Required workflow:
+${workflow}
+
+Blocker contract:
+If the issue is not actually clear enough to write a safe spec, do not invent requirements. Instead, write no spec, make no code changes, keep the reason and questions concise enough to post directly as a \`${needsInfo}\` comment, and return this exact JSON object as the final response:
+{
+  "status": "blocked",
+  "reason": "short reason",
+  "questions": [
+    {
+      "question": "question a human must answer",
+      "recommendedAnswer": "recommended answer and reasoning"
+    }
+  ]
+}
+
+Successful final response:
+Return this exact JSON object after the spec commit succeeds:
+{
+  "status": "spec-created",
+  "specPath": "${specPath}",
+  "commit": "<commit sha>"
+}
+`;
+}
+```
+
+- [ ] **Step 7: Teach plan prompt about spec path**
+
+Update `PlanCreationPromptInput` in `prompts.ts`:
+
+```ts
+export type PlanCreationPromptInput = {
+  issue: IssueSummary;
+  specPath?: string;
+  planPath: string;
+  projectPolicy: PatchmillProjectPolicy;
+  planApprovalRequired?: boolean;
+  skills?: PatchmillSkillsConfig;
+  triageLabels?: Partial<PromptTriageLabels>;
+};
+```
+
+In `buildPlanCreationPrompt()`, destructure `specPath`:
+
+```ts
+const { issue, specPath, planPath, projectPolicy } = input;
+```
+
+Add this workflow step after `renderPlanContextInstruction(projectPolicy)`:
+
+```ts
+specPath
+  ? `Read and base the implementation plan on the approved spec at ${specPath}.`
+  : "No separate spec artifact was found; write the minimum design context needed in the implementation plan before task steps.",
+```
+
+Add this line to the issue data block after labels:
+
+```ts
+${specPath ? `- Spec path: ${specPath}\n` : ""}- Author: ${issue.author ?? "unknown"}
+```
+
+- [ ] **Step 8: Run focused tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/pi.test.ts src/cli/commands/run-once/run-state.test.ts src/cli/commands/run-once/prompts.test.ts

+
+Expected: PASS.

+- [ ] **Step 9: Commit**
+
+```bash

+- [ ] **Step 1: Replace obsolete selection tests**
+
+In `src/cli/commands/run-once/selection.test.ts`, replace the old test named

+  const selected = selectIssue([issue(5, ["spec-approved"])], {
+    readyLabel: ready,
+    issueNumber: 5,
+    approvalPolicy: specApprovalPolicy(),
+  });
+
+  assert.equal(selected?.number, 5);
+});
+```
+
+- [ ] **Step 2: Run failing selection tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/selection.test.ts
+```
+
+Expected: FAIL because selection still only accepts `agent-ready` and still
+filters by required spec approval.
+
+- [ ] **Step 3: Update `selection.ts`**
+
+In `src/cli/commands/run-once/selection.ts`, remove imports of
+`assertExplicitIssueApprovals` and `issueMeetsAutomaticApprovals` from
+`approval-gates.ts`. Import workflow helpers instead:
+
+```ts
+import {
+  assertExplicitWorkflowState,
+  isActionableWorkflowState,
+  resolveWorkflowState,
+} from "./workflow-state.ts";
+```
+
+In `isEligible()`, replace the body with:
+
+```ts
+function isEligible(
+  issue: IssueSummary,
+  options: ResolvedIssueSelectionOptions,
+): boolean {
+  if (issue.state !== "open") return false;
+  if (blockingLabels(issue.labels, options.excludedLabels).length > 0) {
+    return false;
+  }
+
+  return isActionableWorkflowState(
+    resolveWorkflowState(issue.labels, {
+      readyLabel: options.readyLabel,
+      policy:
+        options.approvalPolicy ??
+        createWorkflowApprovalPolicy(DEFAULT_PATCHMILL_CONFIG.workflow),
+    }),
+  );
+}
+```
+
+Add the missing import at the top:
+
+```ts
+import { createWorkflowApprovalPolicy } from "../../../workflow/approval-policy.ts";
+```
+
+In the explicit issue branch, replace the ready-label check and
+`assertExplicitIssueApprovals()` call with:
+
+```ts
+assertExplicitWorkflowState(issue.labels, {
+  readyLabel: resolved.readyLabel,
+  policy:
+    resolved.approvalPolicy ??
+    createWorkflowApprovalPolicy(DEFAULT_PATCHMILL_CONFIG.workflow),
+  issue,
+});
+```
+
+Keep the existing blocking-label check before `assertExplicitWorkflowState()` so
+in-progress/done/protection labels still fail before workflow-state validation.
+
+- [ ] **Step 4: Run selection tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/selection.test.ts
+```
+
+Expected: PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/cli/commands/run-once/selection.ts src/cli/commands/run-once/selection.test.ts
+git commit -m "feat(run-once): select actionable workflow states"
+```
+
+---
+
+## Task 5: Wire spec stage and workflow transitions into the pipeline
+
+**Files:**
+
+- Modify: `src/cli/commands/run-once/pipeline.ts`
+- Modify: `src/cli/commands/run-once/pipeline.test.ts`
+- Test: `src/cli/commands/run-once/pipeline.test.ts`
+
+- [ ] **Step 1: Add focused pipeline tests for the new transitions**
+
+Add a new section near the existing plan-approval tests in
+`src/cli/commands/run-once/pipeline.test.ts`.
+
+Add this helper near existing local helpers if it does not already exist:
+
+```ts
+function specAndPlanApprovalPolicy() {
+  return approvalPolicy({ specRequired: true, planRequired: true });
+}
+```
+
+Add these concrete transition tests. Each mock runner handles the same host
+commands used by adjacent plan-approval tests: issue listing, clean git status,
+label listing, issue edits, comments, and Pi calls.
+
+```ts
+test("runOneIssue writes spec and stops at spec-review when spec approval is required", async () => {
+  const config = await makeConfig({
+    execute: true,
+    dryRun: false,
+    approvalPolicy: specAndPlanApprovalPolicy(),
+  });
+  const selected = issue(31, ["agent-ready", "enhancement"], "Needs spec");
+  const expectedSpecPath = "docs/specs/2026-05-09-issue-31-needs-spec-design.md";
+  const runner = createMockRunner(async (call) => {

+  const finalEdit = editCalls.at(-1);
+  assert.ok(finalEdit);
+  assert.equal(finalEdit.args[finalEdit.args.indexOf("--add-labels") + 1], "spec-review");
+  assert.equal(finalEdit.args.includes("agent-ready"), false);
+});
+
+test("runOneIssue writes plan from spec-approved and cleans spec labels at plan-review", async () => {

+      return { code: 0, stdout: "", stderr: "" };
+    }
+    if (call.command === "pi") {
+      const prompt = await readFile(promptPath(call.args), "utf8");
+      assert.match(prompt, /Create an implementation plan/);
+      assert.match(prompt, new RegExp(specPath.replace(/[.*+?^${}()|[\]\]/g, "\\$&")));
+      return {
+        code: 0,
+        stdout: `plan done
+{"status":"plan-created","planPath":"${expectedPlanPath}","commit":"def456"}`,
+        stderr: "",
+      };
+    }
+    throw new Error(`unexpected command: ${call.command} ${call.args.join(" ")}`);
+  });
+
+  const result = await runOneIssue(runner, config, { now: NOW });
+
+  assert.equal(result.status, "plan-created");
+  assert.equal(result.planPath, expectedPlanPath);
+  const editCalls = runner.calls.filter((call) => call.command === "tea" && call.args[0] === "issues" && call.args[1] === "edit");
+  const finalEdit = editCalls.at(-1);
+  assert.ok(finalEdit);
+  assert.equal(finalEdit.args[finalEdit.args.indexOf("--add-labels") + 1], "plan-review");
+  assert.equal(finalEdit.args.includes("spec-review"), false);
+  assert.equal(finalEdit.args.includes("spec-approved"), false);
+});
+```
+
+Update the existing test
+`runOneIssue proceeds when plan approval label is present and clears plan-review`
+so the selected issue includes all stale workflow labels:
+
+```ts
+const selected = issue(
+  49,
+  [
+    "agent-ready",
+    "spec-review",
+    "spec-approved",
+    "plan-review",
+    "plan-approved",
+    "bug",
+  ],
+  "Approved plan",
+);
+```
+
+In the same test, extend `labelListPayload()` to include `spec-review` and
+`spec-approved`, and replace the claim-call cleanup assertions with final
+cleanup assertions:
+
+```ts
+const editCalls = runner.calls.filter(
+  (call) =>
+    call.command === "tea" &&
+    call.args[0] === "issues" &&
+    call.args[1] === "edit",
+);
+const finalEdit = editCalls.at(-1);
+assert.ok(finalEdit);
+assert.equal(finalEdit.args.includes("spec-review"), false);
+assert.equal(finalEdit.args.includes("spec-approved"), false);
+assert.equal(finalEdit.args.includes("plan-review"), false);
+assert.equal(finalEdit.args.includes("plan-approved"), false);
+```
+
+Add one compact skipped-gate pipeline test for the plan-only approval path. This
+exercises `agent-ready -> plan-review` and proves the first Pi call is spec
+creation and the second Pi call is plan creation:
+
+```ts
+test("runOneIssue writes spec then plan and stops at plan-review when only plan approval is required", async () => {
+  const config = await makeConfig({
+    execute: true,
+    dryRun: false,

+    "Needs spec and plan",
+  );
+  const expectedSpecPath =
+    "docs/specs/2026-05-09-issue-33-needs-spec-and-plan-design.md";
+  const expectedPlanPath =
+    "docs/plans/2026-05-09-issue-33-needs-spec-and-plan.md";
+  let piCalls = 0;
+  const runner = createMockRunner(async (call) => {
+    if (
+      call.command === "tea" &&
+      call.args[0] === "issues" &&
+      call.args[1] === "list"
+    ) {
+      const page = call.args[call.args.indexOf("--page") + 1];
+      return {
+        code: 0,

+
+  assert.equal(result.status, "plan-created");
+  assert.equal(result.specPath, expectedSpecPath);
+  assert.equal(result.planPath, expectedPlanPath);
+  assert.equal(piCalls, 2);
+});
+```
+
+- [ ] **Step 2: Run the failing pipeline tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/pipeline.test.ts
+```
+
+Expected: FAIL because the pipeline does not create specs or use workflow-state
+transitions yet.
+
+- [ ] **Step 3: Import new helpers in `pipeline.ts`**
+
+In `src/cli/commands/run-once/pipeline.ts`, add imports:
+
+```ts
+import { buildSpecPath, findIssueSpec } from "./specs.ts";
+import {
+  cleanupLabelsForImplementation,
+  cleanupLabelsForPlanReview,
+  cleanupLabelsForSpecReview,
+  resolveWorkflowState,
+} from "./workflow-state.ts";
+import {
+  buildImplementationPrompt,
+  buildPlanCreationPrompt,
+  buildSpecCreationPrompt,
+} from "./prompts.ts";
+```
+
+Remove `approvedWorkflowReviewLabelsToRemove` from the approval-gates import
+after the new cleanup helpers replace it.
+
+- [ ] **Step 4: Add comments for spec review**
+
+Near `planComment()` in `pipeline.ts`, add:
+
+```ts
+function specComment(specPath: string, created: boolean): string {
+  return `${created ? "Spec ready" : "Existing spec ready"}: \`${specPath}\``;
+}
+```
+
+- [ ] **Step 5: Resolve workflow state before claiming**
+
+After lifecycle labels are loaded in `runOneIssue()`, add:
+
+```ts
+const workflowState = resolveWorkflowState(issue.labels, {
+  readyLabel: ready,
+  policy: config.approvalPolicy,
+});
+```
+
+Replace the current `workflowReviewLabelsToRemove`/`labels` initialization with:
+
+```ts
+let labels = resumed
+  ? issue.labels.includes(inProgress)
+    ? issue.labels
+    : nextLabels(issue.labels, [ready], [inProgress])
+  : nextLabels(issue.labels, [ready], [inProgress]);
+```
+
+Do not remove `spec-approved` or `plan-approved` at claim time. Later gates need
+the original labels and `workflowState` to decide what stage is being advanced.
+
+- [ ] **Step 6: Add spec path resolution and creation before plan lookup**
+
+Before the existing `let planPath` block in `pipeline.ts`, add:
+
+```ts
+let specPath: string | undefined;
+let specCommit: string | undefined;
+let specCreated = false;
+let specCreatedThisRun = false;
+```
+
+Inside the `try` block, before existing plan lookup, insert a spec-resolution
+section:
+
+```ts
+await progress(options, "info", "spec", "finding spec", {
+  issueNumber: issue.number,
+});
+let savedSpecExists = false;
+if (existingState?.specPath) {
+  const savedSpecPath = repoPath(config.repoRoot, existingState.specPath);
+  try {
+    await access(savedSpecPath.absolute);
+    specPath = savedSpecPath.relative;
+    savedSpecExists = true;
+    specCreated = existingState.checkpoints?.specCreated === true;
+  } catch {
+    specPath = undefined;
+  }
+}
+
+const foundSpec = specPath
+  ? undefined
+  : await findIssueSpec(config.specsDir, issue.number);
+specPath ??= foundSpec
+  ? repoPath(config.repoRoot, foundSpec).relative
+  : promptBodyPath(
+      config.repoRoot,
+      buildSpecPath(
+        config.specsDir,
+        issue.number,
+        issue.title,
+        options.now ?? new Date(),
+      ),
+    );
+const hasExistingSpec = savedSpecExists || foundSpec !== undefined;
+await writeRunState(
+  config.runStateDir,
+  {
+    issueNumber: issue.number,
+    status: "planning",
+    specPath,
+    checkpoints: {
+      specPathResolved: true,
+      ...(specCreated ? { specCreated: true } : {}),
+    },
+  },
+  timestamp,
+);
+checkpoints.specPathResolved = true;
+if (specCreated) checkpoints.specCreated = true;
+```
+
+- [ ] **Step 7: Create the spec when needed**
+
+Immediately after spec path resolution, add:
+
+```ts
+const shouldCreateSpec = !hasExistingSpec;
+if (shouldCreateSpec) {
+  const specResult = await runStep("create spec", async () => {
+    await progress(options, "info", "pi-spec", "creating spec with pi", {
+      issueNumber: issue.number,
+    });
+    return await runPiPrompt(
+      runner,
+      config.repoRoot,
+      buildSpecCreationPrompt({
+        issue,
+        specPath,
+        projectPolicy: config.projectPolicy,
+        specApprovalRequired: config.approvalPolicy.specApproval.required,
+        skills: config.skills,
+        triageLabels: { ready, needsInfo },
+      }),
+      {
+        progress: options.progress,
+        stage: "pi-plan",
+        skillPaths: skillInvocationPaths(
+          [config.skills.planning],
+          config.repoRoot,
+        ),
+        streamOutput: options.streamPiOutput,
+        issueNumber: issue.number,
+        repoRoot: config.repoRoot,
+        heartbeatMs: options.heartbeatMs,
+        tokenUsageState,
+        observeSession: true,
+        verbosePiOutput: options.verbosePiOutput,
+        onObservation: observePi("pi-plan"),
+        taskContract: config.projectPolicy.pi.taskContract,
+        piAgentDir,
+      },
+    );
+  });
+  if (specResult.status === "blocked") {
+    return blockIssue(
+      host,
+      config,
+      issue,
+      labels,
+      specResult,
+      { specPath },
+      timestamp,
+      options,
+    );
+  }
+  if (specResult.status !== "spec-created") {
+    throw new Error(
+      `Expected spec-created from Pi but received ${specResult.status}`,
+    );
+  }
+
+  specPath = repoPath(config.repoRoot, specResult.specPath).relative;
+  specCommit = specResult.commit;
+  specCreated = true;
+  specCreatedThisRun = true;
+  await writeRunState(
+    config.runStateDir,
+    {
+      issueNumber: issue.number,
+      status: "planning",
+      specPath,
+      specCommit,
+      checkpoints: { specCreated: true },
+    },
+    timestamp,
+  );
+  checkpoints.specCreated = true;
+  if (specCommit) await emitSimpleStep(options, issue.number, "commit spec");
+}
+```
+
+If TypeScript complains about `blockIssue()` details not accepting `specPath`,
+update `blockIssue()` details type in the same file to include
+`specPath?: string` and pass it through to run state where appropriate.
+
+- [ ] **Step 8: Stop at spec-review when required**
+
+After spec creation/reuse and before plan lookup, add:
+
+```ts
+const mustStopForSpecReview =
+  config.approvalPolicy.specApproval.required &&
+  workflowState.kind === "agent-ready" &&
+  specCreatedThisRun;
+
+if (mustStopForSpecReview) {
+  const finalLabels = cleanupLabelsForSpecReview(labels, {
+    readyLabel: ready,
+    policy: config.approvalPolicy,
+  });
+  if (!checkpoints.specReadyCommentPosted) {
+    await host.commentIssue(issue.number, specComment(specPath, specCreated));
+    await writeRunState(
+      config.runStateDir,
+      {
+        issueNumber: issue.number,
+        status: "planning",
+        specPath,
+        specCommit,
+        checkpoints: { specReadyCommentPosted: true },
+      },
+      timestamp,
+    );
+    checkpoints.specReadyCommentPosted = true;
+  }
+  await ensureAutomationLabel(
+    host,
+    config,
+    config.approvalPolicy.specApproval.reviewLabel,
+  );
+  await host.applyLabels(planLabelChange(issue.number, labels, finalLabels));
+  labels = finalLabels;
+  await writeRunState(
+    config.runStateDir,
+    {
+      issueNumber: issue.number,
+      status: "finished",
+      specPath,
+      specCommit,
+      checkpoints: { readyLabelRestored: true },
+    },
+    timestamp,
+  );
+  await emitSimpleStep(options, issue.number, "final result spec-created");
+  return withLogPath(
+    {
+      status: specCreated ? "spec-created" : "spec-found",
+      issue,
+      specPath,
+    },
+    options,
+  );
+}
+```
+
+The name `readyLabelRestored` is no longer perfect, but keep it for
+compatibility in this task. Rename checkpoints in a later cleanup only if
+needed.
+
+- [ ] **Step 9: Pass spec path into plan prompt and result objects**
+
+In the existing `buildPlanCreationPrompt()` call, add:
+
+```ts
+specPath,
+```
+
+In every `writeRunState()` call after spec resolution where plan fields are
+written, include `specPath` and `specCommit` when available.
+
+In plan stop returns, change:
+
+```ts
+{
+  status: planCreated ? "plan-created" : "plan-found",
+  issue,
+  specPath,
+  planPath,
+}
+```
+
+- [ ] **Step 10: Use cleanup helpers at plan-review and implementation**
+
+In the plan gate block, replace `labelsToAdd`, `labelsToRemove`, and
+`finalLabels` with:
+
+```ts
+const finalLabels =
+  planGate.action === "stop-for-plan-review"
+    ? cleanupLabelsForPlanReview(labels, {
+        readyLabel: ready,
+        policy: config.approvalPolicy,
+      })
+    : nextLabels(labels, [inProgress], [ready]);
+```
+
+For `stop-for-plan-review`, ensure the final labels also remove `inProgress`:
+
+```ts
+const finalLabels =
+  planGate.action === "stop-for-plan-review"
+    ? nextLabels(
+        cleanupLabelsForPlanReview(labels, {
+          readyLabel: ready,
+          policy: config.approvalPolicy,
+        }),
+        [inProgress],
+        [],
+      )
+    : nextLabels(labels, [inProgress], [ready]);
+```
+
+Before implementation starts, after the plan gate proceeds, update `labels`:
+
+```ts
+const implementationLabels = nextLabels(
+  cleanupLabelsForImplementation(labels, {
+    readyLabel: ready,
+    policy: config.approvalPolicy,

+## Task 6: Update CLI summaries, help, and documentation
+
+**Files:**
+
+- Modify: `src/cli/commands/run-once/main.ts`
+- Modify: `src/cli/commands/run-once/args.test.ts`
+- Modify: `src/cli/commands/run-once/pipeline.test.ts`
+- Modify: `README.md`
+- Modify: `docs/configuration.md`
+- Modify: `docs/issue-agent-workflows.md`
+- Modify: `docs/skills.md`
+- Test: `src/cli/commands/run-once/args.test.ts`, markdown lint
+
+- [ ] **Step 1: Write failing summary/help tests**
+
+In `src/cli/commands/run-once/args.test.ts`, add or update the summary test for
+spec-created:
+
+```ts
+test("summarizeResult includes spec-created details", () => {
+  assert.deepEqual(
+    summarizeResult({
+      status: "spec-created",
+      issue: { number: 42, title: "Spec", body: "", labels: [], state: "open" },
+      specPath: "docs/specs/spec.md",
+      logPath: ".patchmill/runs/run.jsonl",
+    }),
+    {
+      status: "spec-created",
+      issueNumber: 42,
+      specPath: "docs/specs/spec.md",
+      logPath: ".patchmill/runs/run.jsonl",
+    },
+  );
+});
+```
+
+Add an assertion to the existing help text test:
+
+```ts
+assert.match(
+  HELP_TEXT,
+  /Advance one actionable issue through spec, plan, or implementation/,
+);
+```
+
+- [ ] **Step 2: Run failing summary tests**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/args.test.ts
+```
+
+Expected: FAIL because `summarizeResult()` and `HELP_TEXT` do not include
+spec-created semantics yet.
+
+- [ ] **Step 3: Update CLI JSON summary**
+
+In `src/cli/commands/run-once/main.ts`, update `HELP_TEXT` first paragraph:
+
+```ts
+Advance one actionable issue through spec, plan, or implementation workflow states.
+Claims and processes one eligible issue by default.
+```
+
+Update `JsonResult` union with:
+
+```ts
+| {
+    status: "spec-created" | "spec-found";
+    issueNumber: number;
+    specPath: string;
+  }
+```
+
+Update plan-created/plan-found JSON result to optionally include spec path:
+
+```ts
+| {
+    status: "plan-created" | "plan-found";
+    issueNumber: number;
+    specPath?: string;
+    planPath: string;
+  }
+```
+
+Add cases in `summarizeResult()` before plan cases:
+
+```ts
+case "spec-created":
+case "spec-found":
+  return {
+    status: result.status,
+    issueNumber: result.issue.number,
+    specPath: result.specPath,
+    ...withLogPath,
+  };
+```
+
+In the plan cases, include:
+
+```ts
+specPath: result.specPath,
+```
+
+- [ ] **Step 4: Update documentation text**
+
+In `README.md`, replace the current `run-once` bullet with:
+
+```md
+- `patchmill run-once` is the one-issue production run. It advances one
+  actionable issue through spec writing, plan writing, implementation, and any
+  configured human approval stops.
+```
+
+In `docs/configuration.md`, replace the current workflow approval behavior
+section with the four transition tables from
+`docs/specs/2026-06-13-run-once-workflow-advancement-design.md`.
+
+In `docs/issue-agent-workflows.md`, update the selection section to state:
+
+```md
+`patchmill run-once` processes one actionable issue. Actionable labels are the
+configured ready label, the configured spec-approved label, and the configured
+plan-approved label. Review labels without their approved counterparts are
+waiting states and are ignored by automatic selection.
+```
+
+In `docs/skills.md`, update the run-once eligibility sentence so it no longer
+says an issue is eligible only when it has the ready label. Use:
+
+```md
+For `patchmill run-once`, an issue is eligible when it is open, has no
+protection/exclusion label, and carries an actionable workflow label:
+`agent-ready`, `spec-approved`, or `plan-approved` by default.
+```
+
+- [ ] **Step 5: Run summary tests and markdown lint**
+
+Run:
+
+```bash
+node --test src/cli/commands/run-once/args.test.ts
+npm run lint:md
+```
+
+Expected: PASS.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/cli/commands/run-once/main.ts src/cli/commands/run-once/args.test.ts README.md docs/configuration.md docs/issue-agent-workflows.md docs/skills.md
+git commit -m "docs(run-once): describe workflow advancement states"
+```
+
+---
+
+## Task 7: Full verification and cleanup
+
+**Files:**
+
+- Modify only files needed to fix failures found by verification.
+- Test: full run-once suite, full test suite, lint, build.
+
+- [ ] **Step 1: Run the full run-once suite**
+
+Run:
+
+```bash
+npm run test:run-once
+```
+
+Expected: PASS.
+
+- [ ] **Step 2: Run the full test suite**
+
+Run:

+- [ ] **Step 4: Run build**
+
+Run:
+
+```bash

+
+Expected: PASS.
+
+- [ ] **Step 5: Inspect final diff**
+
+Run:
+
+```bash
+git status --short
+git diff --stat
+git diff --check
+```
+
+Expected:
+
+- `git diff --check` prints nothing.
+- Only intentional source, test, and documentation files are changed.
+
+- [ ] **Step 6: Commit final fixes if needed**
+
+If Step 1-5 required any fixes, commit them:
+
+```bash
+git add <fixed-files>
+git commit -m "fix(run-once): complete workflow advancement integration"
+```
+
+If no fixes were needed and the previous task commits already contain all
+changes, skip this commit.
+
+---
+
+## Self-review checklist
+
+Spec coverage:
+
+- `agent-ready`, `spec-approved`, and `plan-approved` are actionable: Task 1 and
+  Task 4.
+- `spec-review` and `plan-review` are waiting states: Task 1 and Task 4.
+- Spec before plan before implementation: Task 3 and Task 5.
+- Approval-gate transition tables: Task 5.
+- Tolerate both review and approved labels: Task 1 and Task 4.
+- Cleanup stale `spec-*` and `plan-*` labels: Task 1 and Task 5.
+- Dry-run/summary/docs reflect state-machine semantics: Task 6.
+- Tests cover selection, pipeline transitions, cleanup, and docs-adjacent
+  behavior: Tasks 1-7.
+
+Placeholder scan:
+
+- The two Task 5 skipped-gate tests contain explicit instructions to replace
+  setup comments with concrete mock code before committing. Do not commit those
+  comments in test code.
+- No production code step uses deferred-work markers or undefined function
+  names.
+
+Type consistency:
+
+- `specPath` and `specCommit` are used consistently across Pi results, run
+  state, prompts, pipeline results, and CLI summaries.
+- `spec-created` mirrors existing `plan-created` naming.
+- `workflow-state.ts` owns label-state decisions; `pipeline.ts` orchestrates
+  side effects.

 # Run Once Workflow Advancement Implementation Plan
 
-> **For agentic workers:** REQUIRED SUB-SKILL: Use
-> superpowers:subagent-driven-development (recommended) or
-> superpowers:executing-plans to implement this plan task-by-task. Steps use
-> checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Make `patchmill run-once` advance issues through spec, plan, and
-implementation workflow states while treating `agent-ready`, `spec-approved`,
-and `plan-approved` as actionable labels.
-
-**Architecture:** Add small pure workflow modules for state resolution and label
-cleanup, then wire those into the existing run-once selection and pipeline. Add
-spec artifact support parallel to existing plan artifact support, and keep
-`pipeline.ts` as orchestration while extracting new deterministic rules into
-focused modules.
-
-**Tech Stack:** TypeScript, Node.js `node:test`, existing Patchmill CLI/host/Pi
-abstractions.

 ## Spec reference
 
-Implement the approved design in:
-
-- `docs/specs/2026-06-13-run-once-workflow-advancement-design.md`
-
-The most important invariants are:
-
-- `agent-ready` means automation may advance the issue.
-- `spec-approved` and `plan-approved` are actionable run-once states.
-- `spec-review` and `plan-review` are waiting states unless the approved label
-  is also present.
-- The agent writes a spec before a plan and a plan before implementation.
-- `run-once` cleans stale `spec-*` and `plan-*` labels when advancing past those
-  stages.
-
-## File structure
-
-Create these focused modules:
-
-- `src/cli/commands/run-once/workflow-state.ts`
-  - Pure label/state resolution for run-once actionable and waiting workflow
-    states.
-  - Pure label cleanup helpers.
-- `src/cli/commands/run-once/workflow-state.test.ts`
-  - Unit tests for state priority, waiting states, approval-required decisions,
-    and cleanup rules.
-- `src/cli/commands/run-once/specs.ts`
-  - Spec artifact filename/path lookup helpers, parallel to `plans.ts`.
-- `src/cli/commands/run-once/specs.test.ts`
-  - Unit tests for deterministic spec paths and lookup.
-
-Modify these existing modules:
-
-- `src/config/types.ts`, `src/config/defaults.ts`, `src/config/load.ts`, and
-  config tests
-  - Add `paths.specsDir` with default `docs/specs`.
-- `src/cli/commands/run-once/types.ts`
-  - Add spec path/commit state and pipeline/Pi result types.
-- `src/cli/commands/run-once/run-state.ts` and tests
-  - Persist spec path/commit and spec checkpoints.
-- `src/cli/commands/run-once/pi.ts` and tests
-  - Parse `spec-created` Pi output.
-- `src/cli/commands/run-once/prompts.ts` and tests
-  - Add `buildSpecCreationPrompt()` and teach plan prompts about a spec path.
-- `src/cli/commands/run-once/selection.ts` and tests
-  - Select actionable workflow states instead of only `agent-ready`.
-- `src/cli/commands/run-once/pipeline.ts` and tests
-  - Orchestrate spec creation/reuse, plan creation/reuse, label transitions, and
-    cleanup.
-- `src/cli/commands/run-once/main.ts` and args tests
-  - Summarize new dry-run transitions and spec-review stop results.
-- `README.md`, `docs/configuration.md`, `docs/issue-agent-workflows.md`,
-  `docs/skills.md`
-  - Update user-facing workflow semantics.
-
-`pipeline.ts` is already large (~1685 lines). Do not add new rule-heavy helpers
-there unless they are only meaningful beside the orchestration. Keep new
-deterministic workflow decisions in `workflow-state.ts` and artifact path logic
-in `specs.ts`.

-- Modify: `src/config/load.ts`
-- Modify: `src/config/defaults.test.ts`

-- Test: `src/config/defaults.test.ts`, `src/config/load.test.ts`,
-  `src/cli/commands/run-once/specs.test.ts`
-
-- [ ] **Step 1: Write failing spec artifact tests**
-
-Create `src/cli/commands/run-once/specs.test.ts`:
-
-```ts
-import test from "node:test";
-import assert from "node:assert/strict";
-import { mkdtemp, writeFile } from "node:fs/promises";
-import { tmpdir } from "node:os";
-import { join } from "node:path";
-import { buildSpecFilename, buildSpecPath, findIssueSpec } from "./specs.ts";
-
-test("buildSpecFilename creates deterministic issue spec filenames", () => {
-  assert.equal(
-    buildSpecFilename(
-      42,
-      "Add reusable pagination widget!",
-      new Date("2026-06-13T10:00:00Z"),
-    ),
-    "2026-06-13-issue-42-add-reusable-pagination-widget-design.md",
-  );
-});
-
-test("buildSpecPath joins configured specs directory and filename", () => {
-  assert.equal(
-    buildSpecPath("docs/specs", 7, "Empty issue", "2026-06-13T12:00:00Z"),
-    join("docs/specs", "2026-06-13-issue-7-empty-issue-design.md"),
-  );
-});
-
-test("findIssueSpec returns the first matching issue spec", async () => {
-  const dir = await mkdtemp(join(tmpdir(), "patchmill-specs-"));
-  await writeFile(join(dir, "2026-06-12-issue-4-other-design.md"), "# Other\n");
-  await writeFile(join(dir, "2026-06-13-issue-5-widget-design.md"), "# Spec\n");
-  await writeFile(
-    join(dir, "2026-06-14-issue-5-widget-v2-design.md"),
-    "# Spec 2\n",
-  );
-
-  assert.equal(
-    await findIssueSpec(dir, 5),
-    join(dir, "2026-06-13-issue-5-widget-design.md"),
-  );
-});
-
-test("findIssueSpec returns undefined when specs directory is missing", async () => {
-  assert.equal(
-    await findIssueSpec(join(tmpdir(), "missing-specs-dir"), 99),
-    undefined,
-  );
-});
-```
-
-Add this assertion to the existing paths assertion in
-`src/config/defaults.test.ts`:
-
-```ts
-specsDir: "docs/specs",
-```
-
-Add this test to `src/config/load.test.ts` near the existing paths tests:
-
-```ts
-test("loadPatchmillConfig parses specsDir path", async () => {
-  const dir = await mkdtemp(join(tmpdir(), "patchmill-config-specs-dir-"));
-  await writeFile(
-    join(dir, "patchmill.config.json"),
-    JSON.stringify({ paths: { specsDir: "engineering/specs" } }),
-    "utf8",
-  );
-
-  const config = await loadPatchmillConfig(dir);
-
-  assert.equal(config.paths.specsDir, "engineering/specs");
-});
-```
-
-Add this assertion to the existing normalized path test in
-`src/config/load.test.ts`:
-
-```ts
-assert.equal(config.paths.specsDir, join(dir, "engineering/specs"));
-```
-
-In that normalized path test's JSON config, include:
-
-```json
-"specsDir": "engineering/specs"
-```
-
-- [ ] **Step 2: Run failing tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/specs.test.ts src/config/defaults.test.ts src/config/load.test.ts
-```
-
-Expected: FAIL because `specs.ts` and `paths.specsDir` do not exist yet.
-
-- [ ] **Step 3: Add `paths.specsDir` to config types/defaults/load**
-
-In `src/config/types.ts`, change `PatchmillPathsConfig` to include:
-
-```ts
-export type PatchmillPathsConfig = {
-  specsDir: string;
-  plansDir: string;
-  runStateDir: string;
-  triageLogDir: string;
-  worktreeDir: string;
-  cleanStatusIgnorePrefixes: string[];
-};
-```
-
-In `src/config/defaults.ts`, update `paths`:
-
-```ts
-paths: {
-  specsDir: "docs/specs",
-  plansDir: "docs/plans",
-  runStateDir: ".patchmill/runs",
-  triageLogDir: ".patchmill/triage-runs",
-  worktreeDir: DEFAULT_GIT_WORKTREE_STRATEGY_CONFIG.worktreeDir,
-  cleanStatusIgnorePrefixes: [".patchmill/runs/", ".patchmill/triage-runs/"],
-},
-```
-
-In `src/config/load.ts`, update `absolutizePaths()` paths:
-
-```ts
-paths: {
-  specsDir: absolutize(root, config.paths.specsDir),
-  plansDir: absolutize(root, config.paths.plansDir),
-  runStateDir: absolutize(root, config.paths.runStateDir),
-  triageLogDir: absolutize(root, config.paths.triageLogDir),
-  worktreeDir: absolutize(root, config.paths.worktreeDir),
-  cleanStatusIgnorePrefixes: cloneStringArray(
-    config.paths.cleanStatusIgnorePrefixes,
-  ),
-},
-```
-
-In `src/config/load.ts`, update `readPatchmillConfigData()` path parsing:
-
-```ts
-const specsDir = readOptionalString(paths, "specsDir", "paths.specsDir");
-const plansDir = readOptionalString(paths, "plansDir", "paths.plansDir");
-```
-
-and later:
-
-```ts
-if (specsDir !== undefined) parsed.specsDir = specsDir;
-if (plansDir !== undefined) parsed.plansDir = plansDir;
-```
-
-- [ ] **Step 4: Add spec path to run-once config**
-
-In `src/cli/commands/run-once/types.ts`, add `specsDir` beside `plansDir`:
-
-```ts
-specsDir: string;
-plansDir: string;
-```
-
-In `src/cli/commands/run-once/args.ts`, set it when constructing `config`:
-
-```ts
-specsDir:
-  normalizedConfig?.paths.specsDir ??
-  join(repoRoot, patchmillConfig.paths.specsDir),
-plansDir:
-  normalizedConfig?.paths.plansDir ??
-  join(repoRoot, patchmillConfig.paths.plansDir),
-```
-
-- [ ] **Step 5: Implement spec artifact helpers**
-
-Create `src/cli/commands/run-once/specs.ts`:
-
-```ts
-import { readdir } from "node:fs/promises";
-import { join } from "node:path";
-
-function slugify(title: string): string {
-  const slug = title
-    .toLowerCase()
-    .replace(/[^a-z0-9]+/g, "-")
-    .replace(/^-+|-+$/g, "");
-
-  return slug || "untitled";
-}
-
-function datePrefix(value: string | Date): string {
-  if (value instanceof Date) {
-    return value.toISOString().slice(0, 10);
-  }
-
-  return value.slice(0, 10);
-}
-
-export function buildSpecFilename(
-  issueNumber: number,
-  title: string,
-  date: string | Date,
-): string {
-  return `${datePrefix(date)}-issue-${issueNumber}-${slugify(title)}-design.md`;
-}
-
-export function buildSpecPath(
-  specsDir: string,
-  issueNumber: number,
-  title: string,
-  date: string | Date,
-): string {
-  return join(specsDir, buildSpecFilename(issueNumber, title, date));
-}
-
-export async function findIssueSpec(
-  specsDir: string,
-  issueNumber: number,
-): Promise<string | undefined> {
-  let entries;
-  try {
-    entries = await readdir(specsDir, { withFileTypes: true });
-  } catch (error) {
-    if ((error as NodeJS.ErrnoException).code === "ENOENT") {
-      return undefined;
-    }
-    throw error;
-  }
-
-  const marker = `-issue-${issueNumber}-`;
-  const match = entries
-    .filter((entry) => entry.isFile() && entry.name.includes(marker))
-    .map((entry) => entry.name)
-    .sort((left, right) => left.localeCompare(right))[0];
-
-  return match ? join(specsDir, match) : undefined;
-}
-```
-
-- [ ] **Step 6: Run focused config/spec tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/specs.test.ts src/config/defaults.test.ts src/config/load.test.ts src/cli/commands/run-once/args.test.ts
-```
-
-Expected: PASS.
-
-- [ ] **Step 7: Commit**
-
-```bash
-git add src/config/types.ts src/config/defaults.ts src/config/load.ts src/config/defaults.test.ts src/config/load.test.ts src/cli/commands/run-once/types.ts src/cli/commands/run-once/args.ts src/cli/commands/run-once/specs.ts src/cli/commands/run-once/specs.test.ts

-## Task 3: Add spec run-state, Pi parsing, and spec prompt
-
-**Files:**
-
-- Modify: `src/cli/commands/run-once/types.ts`
-- Modify: `src/cli/commands/run-once/run-state.ts`
-- Modify: `src/cli/commands/run-once/run-state.test.ts`

-- Modify: `src/cli/commands/run-once/prompts.ts`
-- Modify: `src/cli/commands/run-once/prompts.test.ts`
-- Test: run-state, pi, prompts tests
-
-- [ ] **Step 1: Write failing type/parser/state/prompt tests**
-
-Add this test to `src/cli/commands/run-once/pi.test.ts` near plan-created
-parsing tests:
-
-```ts
-test("parsePiResult parses spec-created result", () => {
-  assert.deepEqual(
-    parsePiResult(
-      'spec done\n{"status":"spec-created","specPath":"docs/specs/spec.md","commit":"abc123"}',
-    ),
-    {
-      status: "spec-created",
-      specPath: "docs/specs/spec.md",
-      commit: "abc123",
-    },
-  );
-});
-```
-
-Add this test to `src/cli/commands/run-once/run-state.test.ts`:
-
-```ts
-test("writeRunState preserves spec path and commit", async () => {
-  const dir = await mkdtemp(join(tmpdir(), "patchmill-run-state-spec-"));
-
-  await writeRunState(dir, {
-    issueNumber: 42,
-    title: "Spec issue",
-    status: "planning",
-    specPath: "docs/specs/spec.md",
-    specCommit: "abc123",
-    checkpoints: { specPathResolved: true, specCreated: true },
-  });
-
-  const state = await readRunState(dir, 42);
-
-  assert.equal(state?.specPath, "docs/specs/spec.md");
-  assert.equal(state?.specCommit, "abc123");
-  assert.deepEqual(state?.checkpoints, {
-    specPathResolved: true,
-    specCreated: true,
-  });
-});
-```
-
-Add this test to `src/cli/commands/run-once/prompts.test.ts`:
-
-```ts
-test("buildSpecCreationPrompt instructs Pi to save and commit the spec", () => {
-  const prompt = buildSpecCreationPrompt({
-    issue,
-    specPath: "docs/specs/2026-06-13-issue-42-add-once-runner-design.md",
-    projectPolicy,
-    specApprovalRequired: true,
-    skills: DEFAULT_PATCHMILL_SKILLS,
-    triageLabels: { ready: "agent-ready", needsInfo: "needs-info" },
-  });
-
-  assert.match(prompt, /Create a design spec/);
-  assert.match(
-    prompt,
-    /docs\/specs\/2026-06-13-issue-42-add-once-runner-design\.md/,
-  );
-  assert.match(
-    prompt,
-    /Stop after writing the spec and wait for explicit manual approval/,
-  );
-  assert.match(prompt, /"status": "spec-created"/);
-  assert.match(
-    prompt,
-    /"specPath": "docs\/specs\/2026-06-13-issue-42-add-once-runner-design\.md"/,
-  );
-});
-```
-
-If `issue`, `projectPolicy`, or `DEFAULT_PATCHMILL_SKILLS` are not already in
-scope in `prompts.test.ts`, reuse the existing fixtures in that file; otherwise
-import them consistently with the current test style.
-
-- [ ] **Step 2: Run failing tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/pi.test.ts src/cli/commands/run-once/run-state.test.ts src/cli/commands/run-once/prompts.test.ts
-```
-
-Expected: FAIL because spec-created parsing, spec state fields, and the prompt
-builder do not exist yet.
-
-- [ ] **Step 3: Extend run-once types**
-
-In `src/cli/commands/run-once/types.ts`, add spec checkpoints:
-
-```ts
-export type AgentIssueRunCheckpoint =
-  | "claimed"
-  | "startedCommentPosted"
-  | "specPathResolved"
-  | "specCreated"
-  | "specReadyCommentPosted"
-  | "planPathResolved"
-  | "planCreated"
-  | "planReadyCommentPosted"
-  | "readyLabelRestored"
-  | "worktreeReady"
-  | "implementationCompleted"
-  | "visualEvidenceUploaded"
-  | "handoffCommentPosted"
-  | "doneLabelEnsured"
-  | "doneLabelApplied";
-```
-
-Add fields to `AgentIssueRunState`:
-
-```ts
-specPath?: string;
-specCommit?: string;
-```
-
-Add fields to `AgentIssueRunStateUpdate`:
-
-```ts
-specPath?: string;
-specCommit?: string;
-```
-
-Add result type:
-
-```ts
-export type AgentIssueSpecCreatedResult = {
-  status: "spec-created";
-  specPath: string;
-  commit?: string;
-};
-```
-
-Update `AgentIssuePiResult`:
-
-```ts
-export type AgentIssuePiResult =
-  | AgentIssueBlockedResult
-  | AgentIssueSpecCreatedResult
-  | AgentIssuePlanCreatedResult
-  | AgentIssuePrCreatedResult
-  | AgentIssueMergedResult;
-```
-
-Update `AgentIssuePipelineResult` to include spec stops:
-
-```ts
-| {
-    status: "spec-created" | "spec-found";
-    issue: IssueSummary;
-    specPath: string;
-  }
-| {
-    status: "plan-created" | "plan-found";
-    issue: IssueSummary;
-    specPath?: string;
-    planPath: string;
-  }
-```
-
-Also add optional `specPath?: string` to blocked and implementation result
-branches so summaries can include it later.
-
-- [ ] **Step 4: Persist spec fields in run state**
-
-In `src/cli/commands/run-once/run-state.ts`, add spec fields to `next` in
-`mergeRunState()`:
-
-```ts
-specPath: update.specPath ?? existing?.specPath,
-specCommit: update.specCommit ?? existing?.specCommit,
-```
-
-After the `if (next.worktreePath === undefined)` block, add:
-
-```ts
-if (next.specPath === undefined) {
-  delete next.specPath;
-}
-if (next.specCommit === undefined) {
-  delete next.specCommit;
-}
-```
-
-- [ ] **Step 5: Parse `spec-created` Pi results**
-
-In `src/cli/commands/run-once/pi.ts`, add this block before the existing
-`plan-created` parser block:
-
-```ts
-if (parsed.status === "spec-created" && typeof parsed.specPath === "string") {
-  return {
-    status: "spec-created",
-    specPath: parsed.specPath,
-    commit: typeof parsed.commit === "string" ? parsed.commit : undefined,
-  };
-}
-```
-
-- [ ] **Step 6: Add spec prompt input and builder**
-
-In `src/cli/commands/run-once/prompts.ts`, add this exported type near
-`PlanCreationPromptInput`:
-
-```ts
-export type SpecCreationPromptInput = {
-  issue: IssueSummary;
-  specPath: string;
-  projectPolicy: PatchmillProjectPolicy;
-  specApprovalRequired?: boolean;
-  skills?: PatchmillSkillsConfig;
-  triageLabels?: Partial<PromptTriageLabels>;
-};
-```
-
-Add this function before `buildPlanCreationPrompt()`:
-
-```ts
-export function buildSpecCreationPrompt(
-  input: SpecCreationPromptInput,
-): string {
-  const { issue, specPath, projectPolicy } = input;
-  const specApprovalRequired = input.specApprovalRequired ?? false;
-  const skills = input.skills ?? DEFAULT_PATCHMILL_SKILLS;
-  const { ready, needsInfo } = resolvePromptTriageLabels(input.triageLabels);
-  const workflow = numberedWorkflow([
-    renderPlanContextInstruction(projectPolicy),
-    `Treat \`${ready}\` as meaning the issue is clear enough for automation to write a design spec. Do not implement code.`,
-    "Write a concise design spec that captures requirements, proposed behavior, affected components, and verification strategy.",
-    `Save the spec to ${specPath}.`,
-    specApprovalRequired
-      ? "Stop after writing the spec and wait for explicit manual approval before planning continues."
-      : "Do not stop for an additional manual spec-approval gate. Continue to planning in the next Patchmill workflow step.",
-    renderTodoWorkflowStep(projectPolicy, "plan", issue.number),
-    "Commit only the spec document using a Conventional Commit message.",
-  ]);
-
-  return `Create a design spec for ${formatIssueTarget(projectPolicy)} #${issue.number}: ${issue.title}
-
-Issue data:
-- Number: #${issue.number}
-- Title: ${issue.title}
-- Labels: ${formatLabels(issue.labels)}
-- Author: ${issue.author ?? "unknown"}
-- Updated: ${issue.updated ?? "unknown"}
-
-${untrustedIssueContentBoundary()}
-
-Issue body:
-${issueBody(issue.body)}
-
-Recent issue comments:
-${formatComments(issue.comments)}
-
-Spec output path:
-${specPath}
-
-Required workflow:
-${workflow}
-
-Blocker contract:
-If the issue is not actually clear enough to write a safe spec, do not invent requirements. Instead, write no spec, make no code changes, keep the reason and questions concise enough to post directly as a \`${needsInfo}\` comment, and return this exact JSON object as the final response:
-{
-  "status": "blocked",
-  "reason": "short reason",
-  "questions": [
-    {
-      "question": "question a human must answer",
-      "recommendedAnswer": "recommended answer and reasoning"
-    }
-  ]
-}
-
-Successful final response:
-Return this exact JSON object after the spec commit succeeds:
-{
-  "status": "spec-created",
-  "specPath": "${specPath}",
-  "commit": "<commit sha>"
-}
-`;
-}
-```
-
-- [ ] **Step 7: Teach plan prompt about spec path**
-
-Update `PlanCreationPromptInput` in `prompts.ts`:
-
-```ts
-export type PlanCreationPromptInput = {
-  issue: IssueSummary;
-  specPath?: string;
-  planPath: string;
-  projectPolicy: PatchmillProjectPolicy;
-  planApprovalRequired?: boolean;
-  skills?: PatchmillSkillsConfig;
-  triageLabels?: Partial<PromptTriageLabels>;
-};
-```
-
-In `buildPlanCreationPrompt()`, destructure `specPath`:
-
-```ts
-const { issue, specPath, planPath, projectPolicy } = input;
-```
-
-Add this workflow step after `renderPlanContextInstruction(projectPolicy)`:
-
-```ts
-specPath
-  ? `Read and base the implementation plan on the approved spec at ${specPath}.`
-  : "No separate spec artifact was found; write the minimum design context needed in the implementation plan before task steps.",
-```
-
-Add this line to the issue data block after labels:
-
-```ts
-${specPath ? `- Spec path: ${specPath}\n` : ""}- Author: ${issue.author ?? "unknown"}
-```
-
-- [ ] **Step 8: Run focused tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/pi.test.ts src/cli/commands/run-once/run-state.test.ts src/cli/commands/run-once/prompts.test.ts
-```
-
-Expected: PASS.
-
-- [ ] **Step 9: Commit**

-## Task 4: Update issue selection to use actionable workflow states
-
-**Files:**
-
-- Modify: `src/cli/commands/run-once/selection.ts`
-- Modify: `src/cli/commands/run-once/selection.test.ts`
-- Test: `src/cli/commands/run-once/selection.test.ts`
-
-- [ ] **Step 1: Replace obsolete selection tests**
-
-In `src/cli/commands/run-once/selection.test.ts`, replace the old test named
-`selectIssue skips spec-unapproved automatic candidates and can choose lower priority approved work`
-with:
-
-```ts
-test("selectIssue automatic selection includes agent-ready when spec approval is required", () => {
-  const selected = selectIssue(
-    [issue(1, [ready, critical]), issue(2, [ready, high, "spec-approved"])],
-    { readyLabel: ready, approvalPolicy: specApprovalPolicy() },
-  );
-
-  assert.equal(selected?.number, 1);
-});
-```
-
-Add these tests after it:
-
-```ts
-test("selectIssue automatic selection includes spec-approved without agent-ready", () => {
-  const selected = selectIssue(
-    [issue(1, ["spec-approved", high]), issue(2, [ready, low])],
-    { readyLabel: ready, approvalPolicy: specApprovalPolicy() },
-  );
-
-  assert.equal(selected?.number, 1);
-});
-
-test("selectIssue automatic selection includes plan-approved without agent-ready", () => {
-  const policyWithPlan = createWorkflowApprovalPolicy({
-    ...DEFAULT_PATCHMILL_CONFIG.workflow,
-    planApproval: {
-      ...DEFAULT_PATCHMILL_CONFIG.workflow.planApproval,
-      required: true,
-    },
-  });
-
-  const selected = selectIssue(
-    [issue(1, ["plan-approved", high]), issue(2, [ready, low])],
-    { readyLabel: ready, approvalPolicy: policyWithPlan },
-  );
-
-  assert.equal(selected?.number, 1);
-});
-
-test("selectIssue automatic selection ignores review-only workflow states", () => {
-  const policyWithBoth = createWorkflowApprovalPolicy({
-    specApproval: {
-      ...DEFAULT_PATCHMILL_CONFIG.workflow.specApproval,
-      required: true,
-    },
-    planApproval: {
-      ...DEFAULT_PATCHMILL_CONFIG.workflow.planApproval,
-      required: true,
-    },
-  });
-
-  const selected = selectIssue(
-    [issue(1, ["spec-review", critical]), issue(2, ["plan-review", high])],
-    { readyLabel: ready, approvalPolicy: policyWithBoth },
-  );
-
-  assert.equal(selected, undefined);
-});
-```
-
-Replace `selectIssue rejects explicit issue missing required spec approval`
-with:
-
-```ts
-test("selectIssue rejects explicit issue waiting for spec approval", () => {
-  assert.throws(
-    () =>
-      selectIssue([issue(5, ["spec-review"])], {
-        readyLabel: ready,
-        issueNumber: 5,
-        approvalPolicy: specApprovalPolicy("spec-ok"),
-      }),
-    (error: unknown) => {
-      assert(error instanceof ApprovalRequiredError);
-      assert.equal(error.missingLabel, "spec-ok");
-      return true;
-    },
-  );
-});
-```
-
-Add:
-
-```ts
-test("selectIssue accepts explicit spec-approved issue without agent-ready", () => {
-  const selected = selectIssue([issue(5, ["spec-approved"])], {
-    readyLabel: ready,
-    issueNumber: 5,
-    approvalPolicy: specApprovalPolicy(),
-  });
-
-  assert.equal(selected?.number, 5);
-});
-```
-
-- [ ] **Step 2: Run failing selection tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/selection.test.ts
-```
-
-Expected: FAIL because selection still only accepts `agent-ready` and still
-filters by required spec approval.
-
-- [ ] **Step 3: Update `selection.ts`**
-
-In `src/cli/commands/run-once/selection.ts`, remove imports of
-`assertExplicitIssueApprovals` and `issueMeetsAutomaticApprovals` from
-`approval-gates.ts`. Import workflow helpers instead:
-
-```ts
-import {
-  assertExplicitWorkflowState,
-  isActionableWorkflowState,
-  resolveWorkflowState,
-} from "./workflow-state.ts";
-```
-
-In `isEligible()`, replace the body with:
-
-```ts
-function isEligible(
-  issue: IssueSummary,
-  options: ResolvedIssueSelectionOptions,
-): boolean {
-  if (issue.state !== "open") return false;
-  if (blockingLabels(issue.labels, options.excludedLabels).length > 0) {
-    return false;
-  }
-
-  return isActionableWorkflowState(
-    resolveWorkflowState(issue.labels, {
-      readyLabel: options.readyLabel,
-      policy:
-        options.approvalPolicy ??
-        createWorkflowApprovalPolicy(DEFAULT_PATCHMILL_CONFIG.workflow),
-    }),
-  );
-}
-```
-
-Add the missing import at the top:
-
-```ts
-import { createWorkflowApprovalPolicy } from "../../../workflow/approval-policy.ts";
-```
-
-In the explicit issue branch, replace the ready-label check and
-`assertExplicitIssueApprovals()` call with:
-
-```ts
-assertExplicitWorkflowState(issue.labels, {
-  readyLabel: resolved.readyLabel,
-  policy:
-    resolved.approvalPolicy ??
-    createWorkflowApprovalPolicy(DEFAULT_PATCHMILL_CONFIG.workflow),
-  issue,
-});
-```
-
-Keep the existing blocking-label check before `assertExplicitWorkflowState()` so
-in-progress/done/protection labels still fail before workflow-state validation.
-
-- [ ] **Step 4: Run selection tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/selection.test.ts
-```
-
-Expected: PASS.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add src/cli/commands/run-once/selection.ts src/cli/commands/run-once/selection.test.ts
-git commit -m "feat(run-once): select actionable workflow states"
-```

-## Task 5: Wire spec stage and workflow transitions into the pipeline
-
-**Files:**
-
-- Modify: `src/cli/commands/run-once/pipeline.ts`
-- Modify: `src/cli/commands/run-once/pipeline.test.ts`
-- Test: `src/cli/commands/run-once/pipeline.test.ts`
-
-- [ ] **Step 1: Add focused pipeline tests for the new transitions**
-
-Add a new section near the existing plan-approval tests in
-`src/cli/commands/run-once/pipeline.test.ts`.
-
-Add this helper near existing local helpers if it does not already exist:
-
-```ts
-function specAndPlanApprovalPolicy() {
-  return approvalPolicy({ specRequired: true, planRequired: true });
-}
-```
-
-Add these concrete transition tests. Each mock runner handles the same host
-commands used by adjacent plan-approval tests: issue listing, clean git status,
-label listing, issue edits, comments, and Pi calls.
-
-```ts
-test("runOneIssue writes spec and stops at spec-review when spec approval is required", async () => {
-  const config = await makeConfig({
-    execute: true,
-    dryRun: false,

-  assert.equal(finalEdit.args[finalEdit.args.indexOf("--add-labels") + 1], "spec-review");
-  assert.equal(finalEdit.args.includes("agent-ready"), false);
-});
-
-test("runOneIssue writes plan from spec-approved and cleans spec labels at plan-review", async () => {
-  const config = await makeConfig({
-    execute: true,

-    if (call.command === "pi") {
-      const prompt = await readFile(promptPath(call.args), "utf8");
-      assert.match(prompt, /Create an implementation plan/);

-  assert.equal(finalEdit.args.includes("spec-review"), false);
-  assert.equal(finalEdit.args.includes("spec-approved"), false);
-});
-```
-
-Update the existing test
-`runOneIssue proceeds when plan approval label is present and clears plan-review`
-so the selected issue includes all stale workflow labels:
-
-```ts
-const selected = issue(
-  49,
-  [
-    "agent-ready",
-    "spec-review",
-    "spec-approved",
-    "plan-review",
-    "plan-approved",
-    "bug",
-  ],
-  "Approved plan",
-);
-```
-
-In the same test, extend `labelListPayload()` to include `spec-review` and
-`spec-approved`, and replace the claim-call cleanup assertions with final
-cleanup assertions:
-
-```ts
-const editCalls = runner.calls.filter(
-  (call) =>
-    call.command === "tea" &&
-    call.args[0] === "issues" &&
-    call.args[1] === "edit",
-);
-const finalEdit = editCalls.at(-1);
-assert.ok(finalEdit);
-assert.equal(finalEdit.args.includes("spec-review"), false);
-assert.equal(finalEdit.args.includes("spec-approved"), false);
-assert.equal(finalEdit.args.includes("plan-review"), false);
-assert.equal(finalEdit.args.includes("plan-approved"), false);
-```
-
-Add one compact skipped-gate pipeline test for the plan-only approval path. This
-exercises `agent-ready -> plan-review` and proves the first Pi call is spec
-creation and the second Pi call is plan creation:
-
-```ts
-test("runOneIssue writes spec then plan and stops at plan-review when only plan approval is required", async () => {
-  const config = await makeConfig({
-    execute: true,
-    dryRun: false,

-  });
-  const selected = issue(
-    33,
-    ["agent-ready", "enhancement"],
-    "Needs spec and plan",
-  );
-  const expectedSpecPath =
-    "docs/specs/2026-05-09-issue-33-needs-spec-and-plan-design.md";
-  const expectedPlanPath =
-    "docs/plans/2026-05-09-issue-33-needs-spec-and-plan.md";
-  let piCalls = 0;
-  const runner = createMockRunner(async (call) => {
-    if (
-      call.command === "tea" &&
-      call.args[0] === "issues" &&
-      call.args[1] === "list"
-    ) {
-      const page = call.args[call.args.indexOf("--page") + 1];
-      return {
-        code: 0,
-        stdout: page === "1" ? issueListPayload([selected]) : "[]",

-          stderr: "",
-        };
-      }
-      return {
-        code: 0,
-        stdout: `{"status":"plan-created","planPath":"${expectedPlanPath}","commit":"def456"}`,
-        stderr: "",
-      };
-    }
-    throw new Error(
-      `unexpected command: ${call.command} ${call.args.join(" ")}`,
-    );
-  });
-
-  const result = await runOneIssue(runner, config, { now: NOW });
-
-  assert.equal(result.status, "plan-created");
-  assert.equal(result.specPath, expectedSpecPath);
-  assert.equal(result.planPath, expectedPlanPath);
-  assert.equal(piCalls, 2);
-});
-```
-
-- [ ] **Step 2: Run the failing pipeline tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/pipeline.test.ts
-```
-
-Expected: FAIL because the pipeline does not create specs or use workflow-state
-transitions yet.
-
-- [ ] **Step 3: Import new helpers in `pipeline.ts`**
-
-In `src/cli/commands/run-once/pipeline.ts`, add imports:
-
-```ts
-import { buildSpecPath, findIssueSpec } from "./specs.ts";
-import {
-  cleanupLabelsForImplementation,
-  cleanupLabelsForPlanReview,
-  cleanupLabelsForSpecReview,
-  resolveWorkflowState,
-} from "./workflow-state.ts";
-import {
-  buildImplementationPrompt,
-  buildPlanCreationPrompt,
-  buildSpecCreationPrompt,
-} from "./prompts.ts";
-```
-
-Remove `approvedWorkflowReviewLabelsToRemove` from the approval-gates import
-after the new cleanup helpers replace it.
-
-- [ ] **Step 4: Add comments for spec review**
-
-Near `planComment()` in `pipeline.ts`, add:
-
-```ts
-function specComment(specPath: string, created: boolean): string {
-  return `${created ? "Spec ready" : "Existing spec ready"}: \`${specPath}\``;
-}
-```
-
-- [ ] **Step 5: Resolve workflow state before claiming**
-
-After lifecycle labels are loaded in `runOneIssue()`, add:
-
-```ts
-const workflowState = resolveWorkflowState(issue.labels, {
-  readyLabel: ready,
-  policy: config.approvalPolicy,
-});
-```
-
-Replace the current `workflowReviewLabelsToRemove`/`labels` initialization with:
-
-```ts
-let labels = resumed
-  ? issue.labels.includes(inProgress)
-    ? issue.labels
-    : nextLabels(issue.labels, [ready], [inProgress])
-  : nextLabels(issue.labels, [ready], [inProgress]);
-```
-
-Do not remove `spec-approved` or `plan-approved` at claim time. Later gates need
-the original labels and `workflowState` to decide what stage is being advanced.
-
-- [ ] **Step 6: Add spec path resolution and creation before plan lookup**
-
-Before the existing `let planPath` block in `pipeline.ts`, add:
-
-```ts
-let specPath: string | undefined;
-let specCommit: string | undefined;
-let specCreated = false;
-let specCreatedThisRun = false;
-```
-
-Inside the `try` block, before existing plan lookup, insert a spec-resolution
-section:
-
-```ts
-await progress(options, "info", "spec", "finding spec", {
-  issueNumber: issue.number,
-});
-let savedSpecExists = false;
-if (existingState?.specPath) {
-  const savedSpecPath = repoPath(config.repoRoot, existingState.specPath);
-  try {
-    await access(savedSpecPath.absolute);
-    specPath = savedSpecPath.relative;
-    savedSpecExists = true;
-    specCreated = existingState.checkpoints?.specCreated === true;
-  } catch {
-    specPath = undefined;
-  }
-}
-
-const foundSpec = specPath
-  ? undefined
-  : await findIssueSpec(config.specsDir, issue.number);
-specPath ??= foundSpec
-  ? repoPath(config.repoRoot, foundSpec).relative
-  : promptBodyPath(
-      config.repoRoot,
-      buildSpecPath(
-        config.specsDir,
-        issue.number,
-        issue.title,
-        options.now ?? new Date(),
-      ),
-    );
-const hasExistingSpec = savedSpecExists || foundSpec !== undefined;
-await writeRunState(
-  config.runStateDir,
-  {
-    issueNumber: issue.number,
-    status: "planning",
-    specPath,
-    checkpoints: {
-      specPathResolved: true,
-      ...(specCreated ? { specCreated: true } : {}),
-    },
-  },
-  timestamp,
-);
-checkpoints.specPathResolved = true;
-if (specCreated) checkpoints.specCreated = true;
-```
-
-- [ ] **Step 7: Create the spec when needed**
-
-Immediately after spec path resolution, add:
-
-```ts
-const shouldCreateSpec = !hasExistingSpec;
-if (shouldCreateSpec) {
-  const specResult = await runStep("create spec", async () => {
-    await progress(options, "info", "pi-spec", "creating spec with pi", {
-      issueNumber: issue.number,
-    });
-    return await runPiPrompt(
-      runner,
-      config.repoRoot,
-      buildSpecCreationPrompt({
-        issue,
-        specPath,
-        projectPolicy: config.projectPolicy,
-        specApprovalRequired: config.approvalPolicy.specApproval.required,
-        skills: config.skills,
-        triageLabels: { ready, needsInfo },
-      }),
-      {
-        progress: options.progress,
-        stage: "pi-plan",
-        skillPaths: skillInvocationPaths(
-          [config.skills.planning],
-          config.repoRoot,
-        ),
-        streamOutput: options.streamPiOutput,
-        issueNumber: issue.number,
-        repoRoot: config.repoRoot,
-        heartbeatMs: options.heartbeatMs,
-        tokenUsageState,
-        observeSession: true,
-        verbosePiOutput: options.verbosePiOutput,
-        onObservation: observePi("pi-plan"),
-        taskContract: config.projectPolicy.pi.taskContract,
-        piAgentDir,
-      },
-    );
-  });
-  if (specResult.status === "blocked") {
-    return blockIssue(
-      host,
-      config,
-      issue,
-      labels,
-      specResult,
-      { specPath },
-      timestamp,
-      options,
-    );
-  }
-  if (specResult.status !== "spec-created") {
-    throw new Error(
-      `Expected spec-created from Pi but received ${specResult.status}`,
-    );
-  }
-
-  specPath = repoPath(config.repoRoot, specResult.specPath).relative;
-  specCommit = specResult.commit;
-  specCreated = true;
-  specCreatedThisRun = true;
-  await writeRunState(
-    config.runStateDir,
-    {
-      issueNumber: issue.number,
-      status: "planning",
-      specPath,
-      specCommit,
-      checkpoints: { specCreated: true },
-    },
-    timestamp,
-  );
-  checkpoints.specCreated = true;
-  if (specCommit) await emitSimpleStep(options, issue.number, "commit spec");
-}
-```
-
-If TypeScript complains about `blockIssue()` details not accepting `specPath`,
-update `blockIssue()` details type in the same file to include
-`specPath?: string` and pass it through to run state where appropriate.
-
-- [ ] **Step 8: Stop at spec-review when required**
-
-After spec creation/reuse and before plan lookup, add:
-
-```ts
-const mustStopForSpecReview =
-  config.approvalPolicy.specApproval.required &&
-  workflowState.kind === "agent-ready" &&

-  if (!checkpoints.specReadyCommentPosted) {
-    await host.commentIssue(issue.number, specComment(specPath, specCreated));

-        issueNumber: issue.number,
-        status: "planning",
-        specPath,
-        specCommit,
-        checkpoints: { specReadyCommentPosted: true },

-    options,
-  );
-}
-```
-
-The name `readyLabelRestored` is no longer perfect, but keep it for
-compatibility in this task. Rename checkpoints in a later cleanup only if
-needed.
-
-- [ ] **Step 9: Pass spec path into plan prompt and result objects**
-
-In the existing `buildPlanCreationPrompt()` call, add:
-
-```ts
-specPath,
-```
-
-In every `writeRunState()` call after spec resolution where plan fields are
-written, include `specPath` and `specCommit` when available.
-
-In plan stop returns, change:
-
-```ts
-{
-  status: planCreated ? "plan-created" : "plan-found",
-  issue,
-  specPath,
-  planPath,
-}
-```
-
-- [ ] **Step 10: Use cleanup helpers at plan-review and implementation**
-
-In the plan gate block, replace `labelsToAdd`, `labelsToRemove`, and
-`finalLabels` with:
-
-```ts
-const finalLabels =
-  planGate.action === "stop-for-plan-review"
-    ? cleanupLabelsForPlanReview(labels, {
-        readyLabel: ready,
-        policy: config.approvalPolicy,
-      })
-    : nextLabels(labels, [inProgress], [ready]);
-```
-
-For `stop-for-plan-review`, ensure the final labels also remove `inProgress`:
-
-```ts
-const finalLabels =
-  planGate.action === "stop-for-plan-review"
-    ? nextLabels(
-        cleanupLabelsForPlanReview(labels, {
-          readyLabel: ready,
-          policy: config.approvalPolicy,
-        }),
-        [inProgress],
-        [],
-      )
-    : nextLabels(labels, [inProgress], [ready]);
-```
-
-Before implementation starts, after the plan gate proceeds, update `labels`:
-
-```ts
-const implementationLabels = nextLabels(
-  cleanupLabelsForImplementation(labels, {
-    readyLabel: ready,
-    policy: config.approvalPolicy,
-  }),
-  [],
-  [inProgress],
-);
-if (implementationLabels.join("\0") !== labels.join("\0")) {
-  await host.applyLabels(
-    planLabelChange(issue.number, labels, implementationLabels),
-  );
-  labels = implementationLabels;
-}
-```
-
-At final done label application, replace:
-
-```ts
-const doneLabels = nextLabels(labels, [inProgress], [done]);
-```
-
-with:
-
-```ts
-const doneLabels = nextLabels(
-  cleanupLabelsForImplementation(labels, {
-    readyLabel: ready,
-    policy: config.approvalPolicy,
-  }),
-  [inProgress],
-  [done],
-);
-```
-
-- [ ] **Step 11: Run pipeline tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/pipeline.test.ts
-```
-
-Expected: PASS.
-
-- [ ] **Step 12: Commit**
-
-```bash
-git add src/cli/commands/run-once/pipeline.ts src/cli/commands/run-once/pipeline.test.ts
-git commit -m "feat(run-once): advance spec and plan workflow states"
-```

-## Task 6: Update CLI summaries, help, and documentation
-
-**Files:**
-
-- Modify: `src/cli/commands/run-once/main.ts`
-- Modify: `src/cli/commands/run-once/args.test.ts`
-- Modify: `src/cli/commands/run-once/pipeline.test.ts`
-- Modify: `README.md`
-- Modify: `docs/configuration.md`
-- Modify: `docs/issue-agent-workflows.md`
-- Modify: `docs/skills.md`
-- Test: `src/cli/commands/run-once/args.test.ts`, markdown lint
-
-- [ ] **Step 1: Write failing summary/help tests**
-
-In `src/cli/commands/run-once/args.test.ts`, add or update the summary test for
-spec-created:
-
-```ts
-test("summarizeResult includes spec-created details", () => {
-  assert.deepEqual(
-    summarizeResult({
-      status: "spec-created",
-      issue: { number: 42, title: "Spec", body: "", labels: [], state: "open" },
-      specPath: "docs/specs/spec.md",
-      logPath: ".patchmill/runs/run.jsonl",
-    }),
-    {
-      status: "spec-created",
-      issueNumber: 42,
-      specPath: "docs/specs/spec.md",
-      logPath: ".patchmill/runs/run.jsonl",
-    },
-  );
-});
-```
-
-Add an assertion to the existing help text test:
-
-```ts
-assert.match(
-  HELP_TEXT,
-  /Advance one actionable issue through spec, plan, or implementation/,
-);
-```
-
-- [ ] **Step 2: Run failing summary tests**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/args.test.ts
-```
-
-Expected: FAIL because `summarizeResult()` and `HELP_TEXT` do not include
-spec-created semantics yet.
-
-- [ ] **Step 3: Update CLI JSON summary**
-
-In `src/cli/commands/run-once/main.ts`, update `HELP_TEXT` first paragraph:
-
-```ts
-Advance one actionable issue through spec, plan, or implementation workflow states.
-Claims and processes one eligible issue by default.
-```
-
-Update `JsonResult` union with:
-
-```ts
-| {
-    status: "spec-created" | "spec-found";
-    issueNumber: number;
-    specPath: string;
-  }
-```
-
-Update plan-created/plan-found JSON result to optionally include spec path:
-
-```ts
-| {
-    status: "plan-created" | "plan-found";
-    issueNumber: number;
-    specPath?: string;
-    planPath: string;
-  }
-```
-
-Add cases in `summarizeResult()` before plan cases:
-
-```ts
-case "spec-created":
-case "spec-found":
-  return {
-    status: result.status,
-    issueNumber: result.issue.number,
-    specPath: result.specPath,
-    ...withLogPath,
-  };
-```
-
-In the plan cases, include:
-
-```ts
-specPath: result.specPath,
-```
-
-- [ ] **Step 4: Update documentation text**
-
-In `README.md`, replace the current `run-once` bullet with:
-
-```md
-- `patchmill run-once` is the one-issue production run. It advances one
-  actionable issue through spec writing, plan writing, implementation, and any
-  configured human approval stops.
-```
-
-In `docs/configuration.md`, replace the current workflow approval behavior
-section with the four transition tables from
-`docs/specs/2026-06-13-run-once-workflow-advancement-design.md`.
-
-In `docs/issue-agent-workflows.md`, update the selection section to state:
-
-```md
-`patchmill run-once` processes one actionable issue. Actionable labels are the
-configured ready label, the configured spec-approved label, and the configured
-plan-approved label. Review labels without their approved counterparts are
-waiting states and are ignored by automatic selection.
-```
-
-In `docs/skills.md`, update the run-once eligibility sentence so it no longer
-says an issue is eligible only when it has the ready label. Use:
-
-```md
-For `patchmill run-once`, an issue is eligible when it is open, has no
-protection/exclusion label, and carries an actionable workflow label:
-`agent-ready`, `spec-approved`, or `plan-approved` by default.
-```
-
-- [ ] **Step 5: Run summary tests and markdown lint**
-
-Run:
-
-```bash
-node --test src/cli/commands/run-once/args.test.ts
-npm run lint:md
-```
-
-Expected: PASS.
-
-- [ ] **Step 6: Commit**
-
-```bash
-git add src/cli/commands/run-once/main.ts src/cli/commands/run-once/args.test.ts README.md docs/configuration.md docs/issue-agent-workflows.md docs/skills.md
-git commit -m "docs(run-once): describe workflow advancement states"
-```

-## Task 7: Full verification and cleanup
-
-**Files:**
-
-- Modify only files needed to fix failures found by verification.
-- Test: full run-once suite, full test suite, lint, build.
-
-- [ ] **Step 1: Run the full run-once suite**
-
-Run:
+- Design: `docs/specs/2026-06-13-run-once-workflow-advancement-design.md`
+- Scope: advance `patchmill run-once` through spec, plan, and implementation
+  workflow states.
+- Actionable labels: `agent-ready`, `spec-approved`, `plan-approved`.
+- Waiting labels: `spec-review`, `plan-review`.
+
+## Durable decisions
+
+1. `patchmill run-once` remains the single automation entrypoint.
+2. Spec creation precedes plan creation when no plan already exists.
+3. A pre-existing plan means the issue can skip spec creation and continue with
+   plan/implementation behavior.
+4. Required spec approval gates any current spec unless the issue currently
+   carries a non-stale `spec-approved` label.
+5. Required plan approval gates any current plan unless the issue currently
+   carries a non-stale `plan-approved` label.
+6. Creating a new spec or plan makes any already-present approval label stale
+   for that artifact.
+7. Review labels are waiting states and should not be selected automatically.
+8. Stage prompts must stay stage-specific: spec prompts write specs, plan
+   prompts manage plan task todos, implementation prompts execute plans.
+9. Filesystem state checks should only translate `ENOENT` to “missing”; all
+   other IO failures must fail loudly with path context.
+
+## Implementation structure
+
+### Workflow state
+
+- Add a canonical workflow-state module for:
+  - resolving actionable vs waiting labels,
+  - explicit issue approval errors,
+  - review-label cleanup rules,
+  - plan approval gate decisions.
+- Remove stale duplicate approval helpers so approval ownership is in one
+  module.
+
+### Workflow artifacts
+
+- Use shared artifact helpers for date prefixes, slugged filenames, issue
+  artifact lookup, and path construction.
+- Keep spec/plan modules as narrow wrappers:
+  - plan filenames: `<date>-issue-<number>-<slug>.md`
+  - spec filenames: `<date>-issue-<number>-<slug>-design.md`
+
+### Planning stage orchestration
+
+- Keep `runOneIssue` focused on selection, claim, implementation, and top-level
+  failure handling.
+- Delegate spec/plan advancement to a shared stage orchestrator that performs:
+  1. resolve saved/found/generated artifact path,
+  2. create artifact with Pi when needed,
+  3. persist run-state checkpoints,
+  4. post ready comments,
+  5. apply review/approval labels,
+  6. return either a final spec/plan result or normalized data for
+     implementation.
+
+### Prompts
+
+- Spec prompt:
+  - writes and commits the spec only,
+  - returns `spec-created`,
+  - does not create/update implementation task todos.
+- Plan prompt:
+  - writes and commits the plan,
+  - creates/updates plan task todos according to the task contract,
+  - returns `plan-created`.
+- Implementation prompt:
+  - consumes the approved plan and task todos,
+  - reports PR/merge/blocker outcomes.
+
+### Selection and summaries
+
+- Automatic selection accepts actionable labels and ignores waiting review
+  labels.
+- Explicit issue selection returns `approval-required` for waiting review
+  labels.
+- Dry-run and CLI summaries report the workflow transition that would be
+  attempted.
+
+## Test plan
+
+Focused behavior tests:
+
+- workflow-state resolution and cleanup rules,
+- spec and plan artifact filename/path/find behavior,
+- prompt contracts for spec, plan, and implementation stages,
+- automatic and explicit issue selection by workflow state,
+- pipeline paths for:
+  - spec creation then spec review,
+  - existing spec then spec review,
+  - stale spec approval after replacement spec creation,
+  - plan creation then plan review,
+  - approved plan advancing to implementation,
+  - saved artifact access failures that are not `ENOENT`.
+
+Verification commands:
 
 ```bash
 npm run test:run-once
-```
-
-Expected: PASS.
-
-- [ ] **Step 2: Run the full test suite**
-
-Run:
-
-```bash
 npm test
-```
-
-Expected: PASS.
-
-- [ ] **Step 3: Run lint**
-
-Run:
-
-```bash
 npm run lint
-```
-
-Expected: PASS.
-
-- [ ] **Step 4: Run build**
-
-Run:
-
-```bash
 npm run build
-```
-
-Expected: PASS.
-
-- [ ] **Step 5: Inspect final diff**
-
-Run:
-
-```bash
-git status --short
-git diff --stat
 git diff --check
 ```
 
-Expected:
-
-- `git diff --check` prints nothing.
-- Only intentional source, test, and documentation files are changed.
-
-- [ ] **Step 6: Commit final fixes if needed**
-
-If Step 1-5 required any fixes, commit them:
-
-```bash
-git add <fixed-files>
-git commit -m "fix(run-once): complete workflow advancement integration"
-```
-
-If no fixes were needed and the previous task commits already contain all
-changes, skip this commit.

-## Self-review checklist
-
-Spec coverage:
-
-- `agent-ready`, `spec-approved`, and `plan-approved` are actionable: Task 1 and
-  Task 4.
-- `spec-review` and `plan-review` are waiting states: Task 1 and Task 4.
-- Spec before plan before implementation: Task 3 and Task 5.
-- Approval-gate transition tables: Task 5.
-- Tolerate both review and approved labels: Task 1 and Task 4.
-- Cleanup stale `spec-*` and `plan-*` labels: Task 1 and Task 5.
-- Dry-run/summary/docs reflect state-machine semantics: Task 6.
-- Tests cover selection, pipeline transitions, cleanup, and docs-adjacent
-  behavior: Tasks 1-7.
-
-Placeholder scan:
-
-- The two Task 5 skipped-gate tests contain explicit instructions to replace
-  setup comments with concrete mock code before committing. Do not commit those
-  comments in test code.
-- No production code step uses deferred-work markers or undefined function
-  names.
-
-Type consistency:
+## Completion checklist
 
-- `specPath` and `specCommit` are used consistently across Pi results, run
-  state, prompts, pipeline results, and CLI summaries.
-- `spec-created` mirrors existing `plan-created` naming.
-- `workflow-state.ts` owns label-state decisions; `pipeline.ts` orchestrates
-  side effects.
+- [x] Workflow state labels modeled centrally.
+- [x] Spec artifact helpers and configuration added.
+- [x] Spec creation result contract added.
+- [x] Selection recognizes actionable approval labels.
+- [x] Pipeline advances through spec, plan, and implementation stages.
+- [x] Spec approval gates existing and newly-created specs.
+- [x] Spec prompt no longer leaks plan-task todo mechanics.
+- [x] Saved artifact access fails fast for non-`ENOENT` errors.
+- [x] Shared artifact helpers eliminate spec/plan copy-paste.
+- [x] Approval ownership consolidated into workflow-state.
+- [x] Oversized implementation plan compressed to durable decisions.
