+
+**Issue 1** commercial MSI path for clean-VM **C** (printer CA parity). Narrative: [DUAL-SHIP.md](DUAL-SHIP.md). Printable A/B/C ticks: [VM-DUAL-SHIP-CHECKLIST.md](VM-DUAL-SHIP-CHECKLIST.md).

+**From repo root on Windows** (Go + WiX v3 `candle`/`light` on PATH). HelperVersion **0.3.6** unless `VERSION=` override.

+| Step | Script | Does | Does **not** |
+|------|--------|------|----------------|
+| 1 | `enable-printer-cas.ps1` | Unwrap `DEFERRED_PRINTER_CAS` body | Build, install, dual-ship pass |
+| 2 | `build-full-msi.ps1` | StageFull + MSI under `wix/out/` | Authenticode; exit 1 if WiX missing |
+| 3 | `dual-ship-smoke.ps1 -VerifyArtifacts` | Print A/B/C; hash local MSI/NSIS | Drive a VM; replace clean-VM C sign-off |
+| 4 | `sign-dry-run.ps1` | `signtool verify` + print sign templates | Live sign / org secrets |
+| 5 | `fill-manifest-sha256.ps1` | Print SHA256SUMS / MD rows | Upload or edit site files |
+
+**Then on clean VM C** (checklist § VM C): default elevated MSI (or `VERAE_SKIP_PRINTERS=0`) → files + IPP/`127.0.0.1:8631` + **Verae Print Helper** task + one-page PDF stamp (receipt/CID ≠ jobId) → uninstall clean. Parity with VM A required.
+
+**Rules**
+
+- Enabling CAs + rebuilding is **not** dual-ship complete — [DUAL-SHIP.md](DUAL-SHIP.md) thin-NSIS exit **A–D** still open.
+- NSIS stays **primary** until live Authenticode + VM C sign-off + site cutover.
+- Hold / jobId is never evidence.
+- Re-disable CAs for files-only tree: `enable-printer-cas.ps1 -Disable`.
+
+**Still left (Issue 1):** org secrets for live CI sign; live notary (macOS); clean-VM **C** sign-off; paste real digests after upload — see [OPEN-ISSUES](../../../../verae-2026-screens/OPEN-ISSUES.md) row 1 · [PUBLISH-DIGESTS.md](../../../docs/PUBLISH-DIGESTS.md) · [CI-SIGN-NOTARY.md](CI-SIGN-NOTARY.md).

 **Prerequisites:** enable deferred CAs in `Product-Full.wxs` via [`../scripts/enable-printer-cas.ps1`](../scripts/enable-printer-cas.ps1) (or manually unwrap `DEFERRED_PRINTER_CAS:OFF` markers); rebuild MSI. `dual-ship-smoke.ps1` prints **VM C BLOCKED** while markers are disabled — enabling is not a dual-ship pass.
