### Prepare the title (Step 18)

Prepare the title in a private file; Step 19 posts that file, never a shell string:

{{FREE_TEXT_FILE:TITLE_FILE=pr-title}}

1. For an existing open PR/MR (not Step 6.5's early PR, which takes item 2), fill the file from the platform, substituting the
   printed name, the matched number and `NEW_VERSION`; no title text passes through you:
   ```bash
   TITLE_FILE="$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.gstack/tmp/<title-file-name>"
   gh pr view <pr-number> --json title -q .title | ~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh <new-version> --stdin > "$TITLE_FILE" || exit 1
   ```
   GitLab reads `glab mr view <pr-number> --output json | jq -r .title` into the same pipe.
2. For a new PR/MR, write `v<NEW_VERSION> <type>: <summary>` into the file with your file-write tool.
3. Every created or updated title MUST start with `v$NEW_VERSION `; check the file with
   `grep -Eq '^v<new-version>( |$)' "$TITLE_FILE"` and never publish an unprefixed title.
4. **NO_VERSION:** replaces items 1-3: keep an existing title (the platform title
   piped straight into the file), or write `<type>: <summary>`; no version prefix.

Save the title file name for Step 19.

## Step 19: Create PR/MR

Recheck Step 18's PR/MR lookup and record it. Errors or ambiguous matches STOP publication.
If the open PR/MR or title changed, repeat Step 18's identity/title preparation,
then return here for a new lookup and a fresh body before publishing.

### Resolve Linked Spec before composing the body

1. Resolve the archive directory and branch:
   ```bash
   GSTACK_STATE_ROOT=$(~/.claude/skills/gstack/bin/gstack-paths --get GSTACK_STATE_ROOT); : "${GSTACK_STATE_ROOT:?gstack-paths failed; reinstall with ./setup or /gstack-upgrade}"
   SLUG=$(~/.claude/skills/gstack/bin/gstack-slug --get SLUG)
   CURRENT_BRANCH=$(git branch --show-current)
   SPEC_ARCHIVES="$GSTACK_STATE_ROOT/projects/$SLUG/specs"
   ```
2. Read archive frontmatter as data, never shell source. Select an exact
   `spec_branch` match to `CURRENT_BRANCH`; among matches use the newest
   `spec_filed_at`. Never infer an issue number from a branch name. If no readable
   match or positive integer `spec_issue_number`, omit only `## Linked Spec` and
   continue composing the PR. Resolve ambiguous matches before linking an issue.
3. Compare that spec's acceptance criteria with Step 8's results. Only fully
   completed Step 8 plan scope permits `Closes #N`, with every spec criterion
   verified. Partial, deferred, failed, dropped or unverified scope uses `Linked to #N`
   and names the remaining work; never auto-close it. Include the archive filename
   and `spec_filed_at`, not a private absolute path; `gstack-post` scans them with the body.

The PR/MR body should contain these sections (never reuse a prior run's body):

```
## Summary
<Read `git log origin/<base>..HEAD --oneline`. Group every substantive commit by
theme, excluding VERSION/CHANGELOG bookkeeping. Do not paste the commit list.>

## Test Coverage
<coverage diagram from Step 7, or "All new code paths have test coverage.">
<If Step 7 ran: "Tests: {before} → {after} (+{delta} new)">
<If Step 7 ran: "Coverage: {X}% value-weighted ({Y}% including {W} weakly covered paths)">
<If Step 7 ran: "Test value: {K} tests written, {R} rejected by the authoring gate, {E} existing tests extended, {W} paths weakly covered (weak = ★, gate-failing or unrated)." Use the singular noun for a count of 1 ("1 test written", "1 existing test extended", "1 path weakly covered").>
<Weak paths and leftover gaps as proposed tests with value cards; each regression test's
"Regression proof — fails at HEAD · passes at base · passes after fix" line; Test value
details for cards whose file type has no known comment syntax.>

## Pre-Landing Review
<findings from Step 9 code review, or "No issues found.">
<Outside review: its verdict; `unverified` or `unavailable` is listed as missing coverage with its reason, never as passed.>

## Exploratory QA
<Step 9's current surfaces/charters, reproducers, approved regressions and red/green
proof, fixes and blocked/inconclusive/not-run coverage. Never present stale or
unavailable results as passing.>

## Design Review
<If design review ran: "Design Review (lite): N findings — M auto-fixed, K skipped. AI Slop: clean/N issues.">
<Detector: "clean" | "N findings (rule-id, rule-id)" | "not installed" | "not cached" | "off" — the state the probe printed; rule ids and counts only, finding text and snippets never reach the PR body.>
<If no frontend files changed: "No frontend files changed — design review skipped.">

## Eval Results
<If evals ran: suite names, pass/fail counts, cost dashboard summary. If skipped: "No prompt-related files changed — evals skipped.">

## Greptile Review
<Step 10 complete: list comments with [FIXED] / [FALSE POSITIVE] / [ALREADY FIXED], or "No Greptile comments." for a successful empty fetch.>
<Step 10 unavailable: include `Greptile triage: UNAVAILABLE (dispatch failed)` and the actual reason.>
<Step 10 no_pr: omit this section.>

## Scope Drift
<If scope drift ran: "Scope Check: CLEAN" or list of drift/creep findings>
<If no scope drift: omit this section>

## Plan Completion
<If plan file found: completion checklist summary from Step 8>
<If Step 8 printed the not-run line: that line verbatim.>
<If plan items deferred: list deferred items>

## Linked Spec
<Closes #N only when the Linked Spec check above permits it; otherwise
"Linked to #N (partial delivery — not auto-closing)" with remaining work and
"Close #N manually after follow-up lands." Include archive filename and filed date.
Without a valid match, omit this entire section.>

## Verification Results
<Step 8.1 obligations executed at Step 9: N PASS, M FAIL, K BLOCKED, J NOT RUN,
not-applicable reasons, unresolved obligations and accepted deferrals.
Unavailable/inconclusive is never PASS.>

## TODOS
<If items marked complete: bullet list of completed items with version>
<If no items completed: "No TODO items completed in this PR.">
<If TODOS.md created or reorganized: note that>
<If TODOS.md doesn't exist and user skipped: omit this section>

## Documentation
<Embed Step 14.5's vetted nonempty `documentation_section` for this invocation:
its saved section file, inserted unchanged by the compose block's `DOCS_SECTION_FILE` lines.
A blocked audit shipped under a user exception has no section file: state its
blocked status, scope and exception here and drop the block's `DOCS_SECTION_FILE` guard
and its `cat -- "$DOCS_SECTION_FILE" && echo &&` step.>
<Always include the status and reviewed scope: updated, current, or blocked with the actual user's named risk exception. Never omit this section or reuse another invocation's audit.>

## Test plan

#### Compose the body, then publish through gstack-post

The PR body is world-readable on a public repo. `gstack-post` scans the exact title
and body bytes it sends and passes them to `gh`/`glab` as arguments, so there is no
separate scan here. Wrap any Codex / Greptile / eval output sections in
tool-attributed fences (` ```codex-review ` / ` ```greptile `) so the scanner
WARN-degrades the example credentials those tools quote instead of blocking the PR
(a live-format credential inside the fence still blocks).

Write the body from above into two private files: the first through the
`## Documentation` heading line, the second from `## Test plan` on.

{{FREE_TEXT_FILE:BODY_TOP_FILE=pr-body-top:BODY_REST_FILE=pr-body-rest}}

In a new shell, restore Step 14.5's saved section file path as `DOCS_SECTION_FILE`
and substitute the printed names. The block deletes both drafts; to change the body,
write fresh ones.

```bash
: "${DOCS_SECTION_FILE:?Restore the saved Step 14.5 section file path before composing}"
PR_BODY_FILE=$(mktemp "${TMPDIR:-/tmp}/gstack-pr-body.XXXXXX") || { echo "ERROR: mktemp failed — cannot compose the PR body; refusing to publish." >&2; exit 1; }
BODY_TOP_FILE="$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.gstack/tmp/<body-top-file-name>"
BODY_REST_FILE="$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.gstack/tmp/<body-rest-file-name>"
[ -s "$BODY_TOP_FILE" ] && [ -s "$BODY_REST_FILE" ] || { echo "Not composed: $BODY_TOP_FILE or $BODY_REST_FILE is empty, so the body was never written. Write both, then rerun." >&2; exit 1; }
{ awk 1 "$BODY_TOP_FILE" && cat -- "$DOCS_SECTION_FILE" && echo && awk 1 "$BODY_REST_FILE"; } > "$PR_BODY_FILE" || exit 1
rm -f "$BODY_TOP_FILE" "$BODY_REST_FILE"
echo "PR_BODY_FILE: $PR_BODY_FILE"
```

In each block below, restore the literal `PR_BODY_FILE` path and substitute Step 18's
title file name; `gstack-post` detects GitHub or GitLab from the remote and the repo's
visibility (an unavailable lookup, including on GitLab, uses the scanner's
public-strict policy). Never re-render the body: every retry sends the same files.

**Existing open PR/MR** (`<pr-number>` from the recheck):

```bash
TITLE_FILE="$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.gstack/tmp/<title-file-name>"
~/.claude/skills/gstack/bin/gstack-post pr-body <pr-number> --body-file "${PR_BODY_FILE:?restore the composed body path}" && \
~/.claude/skills/gstack/bin/gstack-post pr-title <pr-number> --title-file "$TITLE_FILE"
```

It updates the body, then the title, retries a retired-GraphQL edit through REST and
reads the title back. If Step 6.5 opened this PR as an early draft and the user did not
ask for a draft, mark it ready now: `gh pr ready <pr-number>`. Print the existing URL
and continue to Step 20; do not run the create command below.

**No open PR/MR:**

```bash
TITLE_FILE="$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.gstack/tmp/<title-file-name>"
~/.claude/skills/gstack/bin/gstack-post pr-create --base <base> --title-file "$TITLE_FILE" --body-file "${PR_BODY_FILE:?restore the composed body path}"
```

Branch on the exit code of either block:
- **0** posted. Remove `$PR_BODY_FILE` and the title file.
- **1** HIGH finding: BLOCKED — do not publish. Rotate and redact at the source, then
  compose fresh files.
- **2** MEDIUM findings, printed as `RULE:` lines with a `TOKEN:`. AskUserQuestion per
  finding (sterner on public repos, no batch acknowledge). PII offers auto-redact:
  write `~/.claude/skills/gstack/bin/gstack-redact --from-file "$PR_BODY_FILE" --auto-redact <ids>`
  output back into the body file and rerun the block, which scans again. Only when the
  user accepts the findings as they are, rerun the same block with
  `--confirm <confirm-token>` added to the command that printed it; any edit needs a new token.
- **3** `gh`/`glab` failed, or **64** no usable remote or CLI: print the error, the
  branch name, the remote URL and the block for posting by hand. Do not stop — the code
  is pushed — but never report a PR that was not created.
- Any other exit is an error that blocks publication until its cause is fixed.

**Output the PR/MR URL** — then proceed to Step 20.
