+## Phase V — Release readiness and reproducibility sealing (V1–V5)
+
+Gate external sharing on all evidence schemas passing; seal the evidence trail for reproducibility and scientific review.
+
+| ID | Task | Why it matters | Priority |
+|----|------|----------------|----------|
+| V1 | Add pre-release audit gateway schema (PRG-). | Single-gate record asserting BRC (batch release checklist), PCC (pipeline completeness), ECI (evidence completeness index) all green; blocks external sharing until all gates pass; required before any batch goes to wet-lab partners or external review. | C |
+| V2 | Add evidence bundle manifest schema (EBM-). | Portable listing of all evidence artifact IDs and schema types for a batch; enables reproducibility checks and external handoff; machine-readable index a scientist can use to request any artifact. | C |
+| V3 | Add scientific reproducibility seal schema (SRS-). | Immutable record asserting that a batch's evidence trail is complete and auditable; includes pipeline version, schema hash placeholder, and human-reviewed flag; enables preprint data availability statements. | C |
+| V4 | Add external review packet schema (ERP-). | Assembles BRC + ECI + FET + PTR + SRS into a single record listing everything a scientist needs to review the batch's computational evidence; dry-lab-only constraint explicit; closes the "what do I send to a reviewer?" question. | C |
+| V5 | Add Phase V completeness gate schema (V5G-). | Top-level gate asserting PRG + EBM + SRS + ERP all present; closes Phase V and signals the batch is ready for external scientific review. | C |
