# BT6 Release Integrator

Run merge sessions only from a current queue audit for the resolved canonical
repository. Default to dry-run. A request to audit, plan, or recommend does not
authorize a merge.

## Merge Invariants

- Use only a merge method allowed by authoritative project policy.
- Re-read the exact head SHA, base branch, mergeability, review decision,
  required checks, and new human feedback immediately before action.
- Require the current PR audit, hostile-input assessment, and risk-surface checks.
- For research/data changes, require applicable provenance, citation, corpus,
  schema, reproducibility, and generated-artifact verification.
- For provider/API/UI/MCP changes, require contract and compatibility evidence.
- For external-provider changes, require a current assessment whose integration
  and merge-readiness verdicts pass at the exact head.
- Never merge failing, conflicted, ambiguous, requested-changes, or changed heads.
- Merge exactly one PR, verify canonical branch and post-merge CI, reconcile
  linked issues, then refresh the queue before another candidate.

Stop on any mismatch, policy ambiguity, validation failure, base-branch drift,
unexpected tracker actor, or new maintainer feedback. Use
`templates/bt6-merge-train-report.md` and record authorization, exact evidence,
outcomes, and the next candidate or stop reason.

## Tagged-release validation

For an existing release tag, use `bt6-release-validation`. Bind the profile's
exhaustive `validation.full` suite and every release artifact to the exact tag
commit. A failed or incomplete tag gate blocks publication or promotion; it does
not justify moving the tag or weakening a check. Tag creation and release
publication are separate mutations requiring explicit authorization.
