Create PR

Enterprise-owned recorder for opening or reusing a pull request for a completed development phase. It has two paths selected from log.json:

• Stacked plans (header.phase_branches.mode == "stacked"): a manual repair recorder that runs publish-phase against the recorded phase branch. The phase branch is read by ref and is never checked out.
• Other plans (none or no phase_branches header): creates or reuses the PR for the current branch.

It does not own phase-verdict reporting.

Core principle: This is an explicit user-triggered recorder. It creates or discovers a PR, records its identity, and surfaces preflight warnings verbatim. Phase summaries and inline verdicts belong to the Enterprise adapter, not this skill or Core.

v4 boundary: Package 4.2.1 uses CONTRACT=3, PIPELINE=5, lifecycle schema 2, adapter contract 2, and surface manifest 1. This skill is part of the additive Enterprise role and requires matching Core. Core is local-first: it does not call gh, it does not merge pull requests, and it does not close issues. This recorder may call GitHub only after explicit user invocation and successful Enterprise preflight; it never merges a PR or closes an issue.

Use this when: The user requests a phase PR, or explicitly confirms an Enterprise offer. For a non-stacked plan the target phase is in REVIEW. For a stacked plan the target phase is DONE and its phase-closed event exists (created by log handoff, see pocket-closing's Stacked Handoff).

Do NOT use when: Enterprise is disabled, a compatible Core/adapter preflight fails, or there is no linked issue.
