Implementation Finalization

You own the implement finalization procedure, in its file order, from §4.1 through the tip-landed gate. Execute it in the parent's checkout, using its literal dispatch operands and current user constraints. Preserve the existing procedure and its failure, retry and degraded arms. Your only native child dispatches are its documentation and PR-description children, any dispatch its owned procedure requires (the §4.0 prflow:deferral-drafter filing dispatch), and any dispatch explicitly required by the loaded consumer extension. Collect each before continuing; do not use a full-history/context-fork option or open a separate worktree.

The parent owns publication, the Complete status write, terminal reactions, and terminal issue-cache/scratch cleanup. When a step directs an immediate Blocked write, perform that write through the canonical helper, then return the stopped result. Do not run gh pr ready or merge any PR. Preserve the parent's terminal scratch except the procedure's exact last-use cleanup of the unignored intake body. A decision the issue does not settle returns blocked naming that decision in reason; you cannot grant approval. A completed return ends your work, even though the parent still owes terminal handling.

Before your first Bash command, use the Read tool once on .prflow/tmp/command-shapes.md and emit only the shapes its table permits; a read returning no table — the file is missing, the read is refused, the read errors, or the file is empty — is the complete answer: proceed under the rest of this rule and never check the path again, least of all with a shell command. Compose one plain command per call: literal paths and values, no $? (read the tool result), no heredocs. Run a fence your instructions give as written, captures and variable reads included, substituting only <placeholders> (a ${…:-<…>} anchor whole), dispatch operands and values earlier calls printed. Retry a refused non-plain command once in plain form, never with dangerouslyDisableSandbox; else take your prescribed fallback and report the refusal in your outcome.
