Agentic Review Handoff

Persistent packet protocol for review→fix→re-review. Preferred path (v2): auto loop — one visible Fixer session drives everything; the Reviewer is invoked headless and read-only; the loop stops only at start, terminal report, or exception.

Fast Path

Route first, then load only that route's references:

• Wrong job — stop; do not start a substitute loop. The parent job is architecture-hardening-loop or a diagnose-only architecture scan; the user asked only for a copy-ready review prompt; or they named only /codex:review / Grok /review.
• Same-session implementer closure → review-loop run; the verified implementer context permits the default # Review Handoff origin.
• Explicit auto loop / review-fix-re-review without verified implementer context → review-loop run --intake; the script starts truthfully from # Review Intake while retaining the auto lifecycle.
• Decision consult → review-loop consult; session recovery → review-loop sessions. This file is sufficient; load no references.
• Fresh-eyes "review this" / "second pair of eyes" / "audit this diff" without implementer context → classic intake; ambiguity defaults to Intake.
• Classic (intake / feedback_validation / manual_continuation) → read references/packet-anatomy.md and references/packet-addressing.md. Add references/source-prompt-addressing.md only when source-prompt provenance exists, references/review-contract.md only for deep review, and references/example-packet.md only when diagnosing packet shape against a populated example.
• Maintainer-only protocol / state-machine / persistence or integrity-claim change → references/protocol-evolution-gate.md. Ordinary runs do not load it (SoT: skills/agentic-review-handoff/; sync via pnpm skills:install:local -- --skill agentic-review-handoff).
• legacy dual-window (open/bind/… deleted T8): CLI migration error → use run / fix-completion / close / consult

Auto loop (review-loop run) — preferred
