# Pull Request

## Success

I := PR created ∧ pushed ∧ rebased on base
V := `gh pr view {N}` ∧ `git log origin/${BASE}..HEAD` non-empty

Let:
  β := `staging` (∃ origin/staging) ∨ `main`
  Β := current branch
  N := issue# (first number after `/` in Β)

**Stack:** Read `.dev/stack.yml` first — every `{field}` placeholder below resolves from it. ¬∃ → output: "`.dev/stack.yml` not found — run `/R-env-setup` to generate it." and stop.

Β → PR: Conventional Commits title, issue linking, guard rails.

**Flow: single continuous pipeline. ¬stop between steps. Stop only on: REFUSE, explicit Cancel, or Step 6 completion.**

## Pipeline

| Step | ID | Required | Verifies via | Notes |
|------|----|----------|---------------|-------|
| 1 | gather-state | ✓ | state JSON emitted | — |
| 2 | guard-rails | ✓ | ¬REFUSE | — |
| 3 | generate | ✓ | title + body ready | — |
| 4 | create | ✓ | `gh pr create` success | — |
| 5 | rebase | ✓ | `git push` success | — |
| 6 | watch | — | — | inform only |

## Pre-flight

Success: PR created ∧ pushed ∧ rebased on base
Evidence: `gh pr view {N}` returns valid PR
Steps: gather-state → guard-rails → generate → create → rebase
¬clear → STOP + ask: "Which branch are you PR-ing from?"

## Step 1 — Gather State

```bash
bash ${CLAUDE_SKILL_DIR}/gather-state.sh
```

Emits: `branch`, `base`, commit log, diff stat, existing PR, issue number, lifecycle artifacts (analysis, spec), test file count, `falsify_required`, `oracle_ok`, `oracle_reason`, `priced_ok`.

`oracle_ok` / `priced_ok` come from `run-falsify.sh --verify` on `artifacts/reviews/{N}-falsify.json` + spec SC priced scan (`parse-falsify.sh` / `pf_emit_gates`) — markdown alone is ¬the oracle (ADR-019). Missing JSON when τ≠S → `oracle_ok=false` (fail-closed).

## Step 2 — Guard Rails

| Check | Condition | Action |
|-------|-----------|--------|
| Protected branch | Β ∈ {staging, main, master} | **REFUSE.** Create feature branch first. Stop. |
| No commits | `git log origin/${β}..HEAD` empty | **REFUSE.** Nothing to PR. Stop. |
| PR exists | gh pr list → result | → present choice **Update** (`gh pr edit`) \| **Cancel** |
| Branch not pushed | `git ls-remote --heads origin $BRANCH` empty | `git push -u origin $BRANCH` |
| Quality gates | `{commands.lint} && {commands.typecheck}` | Warn on failure, ¬block. Note in PR body if proceeding. |
| Falsify incomplete (τ≠S) | `falsify_required=true` ∧ `oracle_ok=false` | **REFUSE.** Re-run `/R-dev-implement` Step 6b (`run-falsify` → persist `artifacts/reviews/{N}-falsify.json`). Stop. |
| Priced quantity missing (τ≠S) | `priced_ok=false` | **REFUSE.** Re-run `/R-spec` to add `priced`/`not`/`oracles` blocks on fail-closed SCs. Stop. |

(Note: "behind base" is no longer a guard rail — Step 5 rebases post-create automatically. τ=S: skip both rails — `falsify_required=false`.)

## Step 3 — Generate Content

**3a. Commits + diff:**
```bash
git log origin/${BASE}..HEAD --format="%h %s%n%b"
git diff origin/${BASE}...HEAD --stat
```

**3b. Lifecycle artifacts:** already emitted by Step 1 (`issue`, `analysis`, `spec`, `issue_data`, `test_files`, `falsify_*`, `priced_ok`).

N detection: first number after `/` in Β (e.g. `feat/42-slug` → `#42`). ¬found → ask user "Which issue number does this PR close, if any?"

**3c. Title:** `<type>(<scope>): <desc>` (≤70 chars). Type from primary commit purpose. Scope from files: `web | api | ui | config` ∨ omit if cross-cutting.

**3d. Body:** template below.

## Step 4 — Create + Update Issue

Show generated title + body → create immediately (¬ask how). `--draft` → draft.
Failure ∨ explicit edit request → present choice **Edit title/body** | **Cancel**

```bash
gh pr create --title "<title>" --body "<body>" --base ${BASE} [--draft]
# --base <branch> if flag specified (overrides BASE)
```

Display PR URL.

Updating existing PR → `gh pr edit <number> --title "<title>" --body "<body>"`.

## Step 5 — Rebase on Base (post-create)

After PR creation, rebase Β on latest β → force-push with lease → PR updates with current base.

```bash
git fetch origin ${BASE}
BEHIND=$(git rev-list HEAD..origin/${BASE} --count)
```

`BEHIND == 0` → skip rebase, skip push. Log: "Already up to date with origin/${BASE}."

`BEHIND > 0`:
```bash
git rebase origin/${BASE}
# On conflict: → present choice **Resolve manually then re-run /R-pr** | **Abort rebase** (`git rebase --abort`)
git push --force-with-lease origin ${BRANCH}
```

**Safety:** only `--force-with-lease` (not `--force`) — refuses push if remote moved unexpectedly. Only on the feature branch (Β ∉ {staging, main, master} is already enforced in Step 2).

**Why post-create:** ensures the PR reflects the latest base from the moment it lands, so reviewers see a minimal diff and CI runs against current base. Staging can move between branch creation and PR create — this step closes that gap.

## Step 6 — Watch CI

Inform: "CI is running on the PR — use `/R-ci-watch` to monitor it live."

Merge path = gate-driven: `reviewed` label + auto-merge (`gh pr merge --auto --merge`). ¬manual `gh pr merge` while any check is IN_PROGRESS/QUEUED — the gate decides, not the operator.

## PR Body Template

```markdown
## Summary
- {what changed and why}
- {secondary change if applicable}

## Lifecycle

| Phase | Artifact | Status |
|-------|----------|--------|
| Intent | #{N}: {title} | {state} |
| Analysis | [{filename}](artifacts/analyses/{filename}) | Present/Absent |
| Spec | [{filename}](artifacts/specs/{filename}) | Present/Absent |
| Implementation | {N} commits on `{branch}` | Complete |
| Verification | Lint {✅/❌} Typecheck {✅/❌} Tests {✅/❌} ({N} new) | Passed/Failed |

## Test Plan
- [ ] {how to verify}
- [ ] {edge case}

## SC → Test Matrix

Insert persisted `artifacts/reviews/{N}-falsify.md` (optional render of JSON) — do not invent rows. (Step 2 already refused unless `oracle_ok=true`.) Tier S: omit this section entirely — see the Lifecycle note below.

## Falsification Evidence

Insert persisted `artifacts/reviews/{N}-falsify.md` (optional JSON render) — do not invent rows.

Lifecycle notes: S-tier → Intent + Implementation + Verification only. ¬issue → omit Lifecycle + Closes. S-tier → also omit SC → Test Matrix and Falsification Evidence sections.

## Options

| Flag | Description |
|------|-------------|
| (none) | Target auto-detected base branch |
| `--draft` | Create as draft |
| `--base <branch>` | Override base branch |

## Edge Cases

| Scenario | Behavior |
|----------|----------|
| Β ∈ {staging, main, master} | REFUSE: "Create a feature branch first" |
| ¬commits ahead | REFUSE: "Nothing to create a PR for" |
| PR already exists | Offer `gh pr edit` to update |
| ¬N in branch | → ask user link issue or skip |
| Multiple commit types | Use primary type only |
| Lint/typecheck fail | Warn + present choice: **Proceed anyway** \| **Fix first** |
| τ≠S ∧ (`oracle_ok=false` ∨ `priced_ok=false`) | REFUSE — falsify → `/R-dev-implement` Step 6b (`run-falsify`); priced → `/R-spec` |

## Safety Rules

1. ¬PR from `staging`, `main`, `master`
2. ¬`git push --force` — only `--force-with-lease`, and only during Step 5 rebase on feature branches
3. Always show PR content before creation
4. → present choice for all decisions (proceed despite warnings, edit)
5. Always display PR URL after creation
6. Rebase conflicts → abort + defer to user — ¬auto-resolve
7. ¬manual `gh pr merge` while any check is IN_PROGRESS/QUEUED — manual merge mid-CI cancels in-flight runs (`concurrency.cancel-in-progress`) and skips gates. Nominal path: `reviewed` label → auto-merge (`--merge`) on green.
8. τ≠S: ¬create PR while `oracle_ok=false` or `priced_ok=false` — markdown / `falsify_ok` is ¬the oracle. Re-run `/R-dev-implement` Step 6b (`run-falsify`) or `/R-spec` (priced blocks).

## Chain Position

- **Phase:** Build
- **Predecessor:** `/R-dev-implement` (worktree with commits) · or `/R-ship` commit step
- **Successor:** `/R-ci-watch` (via `/R-dev`) · or `/R-dev-review` (via `/R-ship`)
- **Class:** adv (continuous flow, no gate)

## Task Integration

- `/R-dev` owns the dev-pipeline task lifecycle externally
- This skill does NOT update its own dev-pipeline task
- Sub-tasks created: none

## Exit

- **Success via `/R-dev`:** PR created + rebased + pushed → return control silently. ¬write summary. ¬ask user. ¬announce `/R-ci-watch`. `/R-dev` re-scans and advances.
- **Success standalone:** print PR URL + `Next: /R-ci-watch --pr {PR#}`. Stop.
- **Failure (REFUSE, rebase conflict, gh error):** return error. `/R-dev` presents Retry | Skip | Abort.
