Hongming Wang 199630908d fix(publish-runtime): smoke test asserts stable invariants, not feature flags (#2112) ... The original smoke step had `assert a2a_client._A2A_QUEUED_PREFIX` which is a feature-flag-style check — it fires false-positive every time staging is mid-release of that specific feature. Caught when the dry-run publish (run 24965411618) failed because _A2A_QUEUED_PREFIX hadn't landed on staging yet (it lives in PR #2061's series, separate from the PR #2103 chain that shipped this workflow). Replaced with checks for stable invariants of the package contract: - a2a_client._A2A_ERROR_PREFIX exists (always has, since the [A2A_ERROR] sentinel is the foundational error-tagging primitive) - adapters.get_adapter is callable - BaseAdapter has the .name() static method (interface anchor) - AdapterConfig has __init__ (dataclass present) These four cover the cases the smoke test actually needs to catch: import-path rewrites broken by build_runtime_package.py, missing modules, dataclass shape regressions. They don't fire when a specific feature is mid-merge. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Hongming Wang <hongmingwangalt@gmail.com>		2026-04-26 13:14:15 -07:00
