Transport-level failures from httpClient.Do (connection refused/reset,
DNS, TLS, timeouts) were wrapped as plain errors, so they fell through
userFriendlyActivationError's LicenseServerError branch to the generic
contact-support fallback instead of the retryable temporarily-unavailable
message. Users behind flaky networks got a dead-end message, and the
2026-08-01 rc.6 paid-runtime gate failure was misdiagnosed the same way.
Classify Do failures at the client layer as a retryable LicenseServerError
(code license_server_unreachable, StatusCode 0 so revocation/suspension/
migration status gates never match) with the cause reachable via Unwrap so
the status poller's context.Canceled check keeps working. The cloud-paid
transport boundary contract now names this classification. Tests pin the
classification, the cancellation chain, and the end-to-end user-facing
retryable message.
