/rosetta-preflight — deterministic preflight JSON

Rosetta's deterministic CLI is local and does not call external APIs except rosetta preflight --allow-ra1-github, which delegates GitHub-dependent checks to RA1. Agent-run external-source collection for ADR 0012 is outside the deterministic CLI, opt-in, may use authenticated MCP/network tools, and may only feed rosetta ingest records as Status: Proposed drafts pending human confirmation. Rosetta is read-only against transcript stores and product source by default; default writes are limited to .agents/**, decisions/**, and loop-runs/**, plus the allowlisted harness docs only under explicit harness export --apply. Rosetta records, cites, and checks evidence; it never runs product builds/tests/deploys, asserts behavior, schedules loops, merges/pushes, or grades autonomy.

Workflow

Run the canonical top-level command; do not use a nested rosetta loop namespace:

rosetta preflight \
  --project-root <project> \
  --decisions-root <decisions-root> \
  --scope "<decision-query>" \
  --min-coverage 0.8 \
  [--changed-path <path> ... | --diff-file <path-or-> | --base <rev> --head <rev>] \
  [--change-id <stable-id>] \
  [--allow-ra1-github]

Interpret the output sections by owner:

• ra1_structural (owner: ra1) — structural readiness JSON from RA1, or skip when RA1 is absent.
• decision_state (owner: rosetta) — current decision resolution for --scope; fails on conflict, ambiguous alias, stale current records, or non-unique matches.
• gates (owner: rosetta) — the same pure gate report as rosetta gates check.

Exit 1 means at least one section failed. Exit 0 means the deterministic preflight report was generated with no failing sections; execution policy remains outside Rosetta.
