Reversible Vast.ai Client and Template Upgrade

Overview

Treat the provider client and workload template as separate compatibility boundaries. Pin and test the managed CLI or PyPI package, preserve the vastai_sdk compatibility shim during migration, and canary template changes before a rolling update.

Prerequisites

• Current CLI/SDK version, install channel, import usage, commands, templates, and dependent automation
• Target version and release evidence plus contract tests for critical commands and response adapters
• Rollback client version, prior template hash, and an acceptance deadline

Instructions

Step 1: Freeze the current contract

Record versions, install location, key precedence, imports, command help, structured outputs, and immutable template/model identities.

Step 2: Upgrade in isolation
