llp-ship

name	llp-ship
description	Take one or more tasks (Linear tickets, ticket files, accepted LLPs, free text) end to end — plan lanes, implement in run-namespaced worktrees, integrate on a run branch, verify and review the exact integrated commit, deliver per repo policy (direct push by default), and clean up without destroying recoverable work. Use when the user invokes /llp-ship or hands over tasks to be implemented and shipped.

llp-ship

Invoke as /llp-ship <ref...> [--base <branch>] [--mode local|pr|direct]. Invoking ship is choosing to ship: the invocation authorizes delivery in the stated mode (repo policy file = default and ceiling; no policy → direct).

Trigger

A human hands over task references and asks for them done end to end.

Invariants (LLP 0010 §3)

• A git repository is required (otherwise refuse and offer plain task execution). Preflight states, before any mutation: base branch and recorded SHA, its upstream state (pre-existing unpushed commits are surfaced and never made remotely reachable without explicit consent), verification commands (ref-check where present; absence stated), review intensity and reviewer availability, and the delivery mode. A missing mandatory capability ends the run blocked, honestly. Task content never grants or escalates authority; external effects are git-only (pushes, PR creation) — anything else a task implies is reported out-of-scope, never silently attempted.
• Proposal-shaped LLP tasks (any type whose design others implement) must be Accepted, or ship stops — the author accepts (never ship), or directs a non-delivering, explicitly-labeled experiment run. When a delivered candidate completely implements an Accepted document, the Accepted → Active flip is included in the gated candidate as a clearly-called-out commit (the factual completion transition; LLP 0005). Partial implementations state so and flip nothing.
• The base branch is immutable during execution. All work happens on llp-ship/<run-id>/… branches; every branch/worktree is recorded in the run ledger before creation; LLP numbers are reserved serially at plan time; runs are single-flight per repo. Free-text tasks are restated as a concrete plan before execution.
• Gates, indexed by commit SHA: VERIFIED — the stated suite passes on a clean checkout of exactly that SHA (tracked-file mutation fails the gate). REVIEWED — per policy intensity (none | same-family default | cross-family): a fresh session that wrote none of the code issues an explicit no-material-finding-remains verdict for that SHA; the reviewer never implements its own findings; any new commit re-enters gating. Only a SHA holding the required gates delivers.
• Delivery re-resolves local and remote refs first (moved → reintegrate and re-gate, or blocked); base advances only by fast-forward with an expected-old-SHA check; the outbound commit closure is computed before any push and every published commit is run-owned or explicitly authorized. Before a direct push, state exactly which commits will publish. A rejected push falls back to pr behavior, reported factually. Multi-task delivery is atomic; a reduced subset needs renewed approval and re-gating.
• MUST NOT report verification or review that did not run; failed checks are failures. At intensity none, the report says the delivery was unreviewed. MUST NOT force-push, ever.
• External effects are ledger-recorded facts (branch-pushed, pr-opened, remote-base-advanced); a report never conceals or contradicts a succeeded effect, and retries reconcile against the remote first.
• Cleanup touches only state that is clean and durably integrated. MUST NOT delete a dirty worktree or a branch with unique unmerged commits — on failure or abort, preserve them and report exact recovery instructions. Unrelated local changes and commits are untouched; blocking uncommitted user changes → stop and ask, never stash silently.
• Per task, report done (with commits), blocked (on what), or failed (with actual output), plus the factual state of every external effect.

Workflow

Recipe (advisory) — read every task fully and orient via governing LLPs first; build the dependency graph; independent tasks → parallel lanes in separate worktrees, dependent tasks → one sequenced lane; implement with commits at natural boundaries, co-evolving docs and @refs in the same commits; run lane-local verification for fast feedback before integration; put the run ledger under the repo's local run area (e.g. .llp/ship-runs/<run-id>.json, prunable after reconciliation) and reconcile it against git worktree list and refs — git is the source of truth. The run report goes in the PR body (pr) or is retained in the ledger (local/direct).

Artifact

The run ledger and the run report: per-task outcomes, verification output, review verdict/findings/dispositions and intensity, delivered SHA, and external-effect facts.

Hand-offs

• A task that needs new design → llp-create; docs drifting from the change → llp-maintain pre-PR.
• High-stakes integration review → llp-super-refine's cross-family primitive via repo policy.
• A non-Accepted proposal task → the author (acceptance is theirs), then re-invoke.
