"""Tests for system-prompt model-identity sync across provider failover.
|
|
|
|
The system prompt is session-stable and embeds ``Model:``/``Provider:``
|
|
identity lines. When ``try_activate_fallback`` swaps the runtime, the
|
|
prompt must be rewritten in place (and synced into the in-flight
|
|
``api_messages``) or the agent reports the primary model's name while a
|
|
fallback model is answering — e.g. a local gemma fallback claiming to be
|
|
gpt-5.4-mini after a Codex usage-limit 429.
