Spectre Ship

ship

Own cleanup, rebase, advisory suite, and draft PR.

Inputs

• $ARGUMENTS: optional feature root/artifact, target (default origin/main), feedback focus, or --draft; live branch/tree/remotes/PR state.

Feature root

• Reuse a managed FEATURE_ROOT only when explicit/current-thread evidence ties it to this work (physical directory wins; never branch/recency/lifecycle/scans); distinct work ignores ambient roots. Otherwise, including on collision, standalone MUST first load and follow @skill-spectre:spectre-feature-root through DONE; orchestrated calls escalate. Keep writes beneath it and pass it unchanged.

Proof independence

Proof is optional: do not inspect, infer, invoke, or gate on it. Only authority/publication-safety impasses prevent PR creation.

Outputs + DONE

• Return PR URL, commits, rebase/tested SHA, verification/repairs, CI: pending, measurement, and PR_OPENED status PASS|REPAIRED|PRE_EXISTING_FAILURES|INDETERMINATE|KNOWN_FAILURES_REMAIN.

DONE when: Prune analysts/Test testers finish their gates, then Sweep, rebase, one full suite, repair/routing, measurement relay/degradation, and PR URL. Non-green verification never prevents DONE.

Method / guardrails

1. Resolve once. Confirm branch/target/set; reject main/master. Read the exact branch; never derive work identity from branch, recency, or ambient roots — selection binds to the frozen post-rebase candidate. FEATURE_ROOT is artifact-only. Reuse unambiguous ancestral CLEANED_THROUGH_SHA. Invoke spectre-workflow measure start --label Ship; below, measure means spectre-workflow measure.
2. Parallel cleanup boundary. Classify P0-P3; invoke measure start for Prune/Test. Load ${CLAUDE_PLUGIN_ROOT}/skills/spectre-ship/references/prune.md and ${CLAUDE_PLUGIN_ROOT}/skills/spectre-ship/references/test.md with the set/risk/FEATURE_ROOT/--orchestrated. Skill loading imports instructions, not phase delegation: the primary owns both contracts and makes one parallel dispatch of leaf @spectre:analyst/@spectre:tester batches; no phase child spawns agents. Neither stages/commits. Invoke measure finish after all batches, attaching a child identity only when singular; relay compact paths/checks and repair/route cross-boundary needs unless NEEDS_AUTHORITY.
3. Sweep. Start measure start --label "Sweep"; load ${CLAUDE_PLUGIN_ROOT}/skills/spectre-ship/references/sweep.md with --orchestrated, unchanged set, and both results. It alone integrates stale/uncovered checks, repairs attributable failures, and commits; invoke measure finish for the Sweep snapshot.
4. Rebase. Start measure start --label "Rebase"; load ${CLAUDE_PLUGIN_ROOT}/skills/spectre-ship/references/rebase.md with target, --orchestrated --verification-owner parent; retain backup summary. No checks; invoke measure finish for the Rebase snapshot.
5. Observe one full suite after rebase. At FULL_SUITE_SHA, derive and freeze candidate {repository, base, head, diff} as EXPECTED_BASE_SHA/EXPECTED_HEAD_SHA/EXPECTED_DIFF_SHA256. Before the first PR side effect, select against that frozen tuple with knowledge-cli.mjs work membership --branch <exact-branch> --candidate <tuple-json>; freeze its selected work-ID set and report excluded/ambiguous without substituting recency. Still before Create PR, invoke Skill(spectre-work-record) per selected record: finalize a complete one with execution.state finalized and remainingWork exactly None.; refresh a blocked/incomplete one truthfully and never finalize it. No PR, CI, review, or readiness value enters remainingWork. Then invoke measure start --label "Full suite" and measure start --label "Create PR". In parallel run the full-suite lane and Skill(spectre-create_pr) pending with target, --orchestrated --pr-phase pending, the frozen set, and the tuple; it returns a draft with local verification RUNNING. At each end invoke measure finish with child identity when available. No duplicate suites or raw child output.
   • Attribute failures branch-caused|unrelated|indeterminate, preferring target-SHA CI and otherwise reproducing only the failing check at target.
   • Repair branch-caused families; rerun only failing/affected checks, never the full suite. Route unrelated/indeterminate findings; record repaired HEAD and CI: pending.
   • Verification is evidence, never a stop condition.
6. Create PR and measure. After suite call Skill(spectre-create_pr) with target, --orchestrated --pr-phase final-update, URL/body, the same frozen set, refreshed tuple, and FINAL_VERIFICATION_SUMMARY; change Testing only. Refresh claims after repairs; on PR_CANDIDATE_STALE, refresh and retry. Once PR identity exists, re-run work membership against the final tuple after any repair; a record it no longer proves is reported, not associated. Annotate the still-selected set through one work associate --work-id <id> … --pull-request-id <id> --candidate <final-json> --pull-request <json>, replaying retry.expectedRevisions via --expected-revisions until associated/noop and reporting partial remaining. Association annotates only: it never confers finality, PR state is draft-open, never merged, and a later Execute run on this branch keeps its own record and joins this same PR only when the updated candidate proves membership. Ambiguity or capture failure returns recovery input but does not block PR. Run measure summary --rows … --outer-snapshot … --persist --project-dir … --feature-root "$FEATURE_ROOT" --base-sha "$EXPECTED_BASE_SHA" --head-sha "$EXPECTED_HEAD_SHA" --diff-sha256 "$EXPECTED_DIFF_SHA256"; relay table, persistence status, and history path. Persistence degradation never blocks PR completion; never inspect transcripts, track clocks, or calculate. Unattributed Prune/Test and Full suite/Create PR use one exact parallel-group total; unavailable measurement never blocks Ship.
