This route is canonical at the URL level today. The existing rich replay UI lives at /replay (with Replay + ProvenancePanel + ChainAbstractionAuditTrail + TimelineScrub primitives composed correctly). Cycle 102 adds two new primitives here: EvidenceBundleExport (JSON serializer · download via Blob) and ProofVerifier (paste-or-upload bundle · sha256 chain check · verified chip).
Per user guardrail: JSON is the only format shipped at cycle 102. CBOR + PDF appear as coming-soonchips in the format picker.
