• @parity/product-sdk-cloud-storage ^0.6.4
• @parity/product-sdk-descriptors ^0.6.1
• @parity/product-sdk-keys ^0.3.10
• @parity/product-sdk-tx ^0.2.14
• @parity/polkadot-app-deploy 0.11.0
• @parity/dotns-cli 0.7.2
• @parity/cdm-builder 3.1.7, @parity/cdm-codegen 0.6.20, @parity/cdm-env ^2.0.6

Target versions (latest)

• @parity/product-sdk-terminal 0.6.2
• @parity/product-sdk-contracts 0.9.2
• @parity/product-sdk-cloud-storage 0.8.1
• @parity/product-sdk-descriptors 0.8.0
• @parity/product-sdk-keys 0.3.16
• @parity/product-sdk-tx 0.3.2
• @parity/polkadot-app-deploy latest 0.13.x
• @parity/dotns-cli latest
• @parity/cdm-* latest

Breaking change to plan for

@parity/product-sdk@0.18.0 introduced the Result based error API (submitAndWatch, batchSubmitAndWatch, contract .tx / .prepare, ensureContractAccountMapped, cloud storage queryJson). CLI command handlers that wrap these in try/catch need to inspect the Result and keep the existing error message prefixes.

What needs to happen

• Bump the @parity/product-sdk-* packages, @parity/polkadot-app-deploy, @parity/dotns-cli, and the @parity/cdm-* tools to the versions above.
• Migrate command handlers to the Result error API while preserving user facing messages.
• Re-check the local pnpm patches against the new versions and drop any fixed upstream.
• Run dot init, an install, and a deploy end to end.

Acceptance criteria

• The CLI builds and the e2e suite passes.
• dot init, install, and deploy all work against a live environment.
• No stale @novasamatech or CDM version pins remain that are no longer needed.
