Phase 5 — external-review workflows #11

Scope (ROADMAP.md, Phase 5) — FUTURE WORK (not in the Phases 1–4 milestone)

• Human L4 gates.
• Reproduction bundles.
• Prediction tracking and demotion on contradicting evidence.

Acceptance checklist (draft, to be refined when scheduled)

• Human-gated L4 promotion workflow (explicit human identity + rationale recorded in the ledger).
• Reproduction bundles: one-command replay of a candidate's full evidence trail from the ledger.
• Prediction registry: candidates make trackable predictions; contradicting evidence triggers demotion with reason.
• Tests green; docs updated.

Dependencies

Blocked by #9 — Phase 3 epic (L3 panels precede external review) and #10 — Phase 4 epic (real adapters supply realistic review workloads).
